Résumé :

According to the characteristics of the vehicle active chassis system, multi-model system including Electric Power Steering System (EPS), Anti-lock Braking System (ABS) and Semi-active Suspension system (SAS) is established. Then, using the strategy of intelligent hierarchical control, the coordinated controller of active chassis system is designed. The bottom layer controller includes 3 separate controllers, i.e., suspension, steering and braking system controllers. They are used to carry out different control tasks and achieve performance indexes of subsystems. The upper layer coordinated controller is used to judge the vehicle states. At the same time, combined with the vehicle chassis coordinated control logic and the characteristics of feed-back information coming from the bottom controllers, the upper coordinated controller make whole coordination and control decision-making to vehicle active chassis subsystems. The simulation results show that the intelligent hierarchical control can improve the vehicle operational performances effectively.

Résumé :

In control system of vehicle chassis, two integrated control sub-systems of chassis have achieved some better results than a single sub-system control. However the two integrated sub-system control can not improve some dynamic performance on vehicle when other sub-system of chassis is disturbed. In order to improve vehicle dynamic performance of some sub-system, an integrated control method based on multi-system with suspension, steering system and brake system is designed. In the model, a 14-DOF vehicle model is used, and an integrated control method based on multi-system of chassis is designed in software of Matlab/Simulink with an integrated controller of PID. Simulation results show that the overall vehicle performance based on the three integrated control systems of chassis is better than those of two integrated control system.

Résumé :

To improve the stability of forestry chassis on the slope, a chassis-installed barycenter adjustable mechanism (BAM) is designed, and the control method of the counterweight is proposed to make the chassis barycenter move suitably to achieve the design purpose. The kinematic analysis of BAM is carried out, and the relationship between the translation, rotation, and vertical displacement of counterweight and the chassis barycenter is calculated. Furthermore, the variation curves obtained in Matlab show the barycenter can translate 100 mm, rotate from 0 to 360 degrees, and lower about 180 mm in the vertical direction. Adams is adopted to complete the kinematics simulation of the chassis, indicating that the control method can effectively adjust the barycenter position. Finally, experiments are carried out under slope conditions to analyze chassis stability by testing plantar pressure. The results show that forest chassis using the barycenter control method helps keep stable on the slope of 15 degrees, much better than standard normal chassis.

Résumé :

In order to solve the straight line drive coordinated control problem of the four-wheel independent drive sprayer chassis, the dynamic model of sprayer chassis and electromagnetic proportional valve controlled hydraulic motor model are established. The additional yaw moment is designed to rectify the deviation with sliding mode variable structure control. PID control strategy is used to calculate the control voltage adjustment of the electromagnetic proportional valve. The simulation results show that the accumulative deviation of the chassis is 0.2 m out of 100 m when the coordinated control strategy is adopted on different adhesive coefficient pavement, which is much smaller than the value without control. The test results of test prototype show that the yaw acceleration of the chassis can be as low as −0.0132 m/s2 on different adhesive coefficient pavement with coordinated control, which is smaller than the value without control, and the straight line drive requirements are met. It is feasible to combine sliding mode variable structure with PID control and use the electromagnetic proportional control technology in the straight line drive coordinated control of sprayer chassis by adding the yaw moment to rectify the deviation of chassis based on the yaw acceleration detection.

Résumé :

Aiming at the differences of vehicle chassis key subsystems influence on vehicle handling stability and effective acting regions, comprehensive considering of the nonlinear characteristic of the tires and the dynamic coupling among suspension, steering, and braking subsystems in vehicle chassis, the 14-DOF full vehicle model is built. Based on the control characteristic local optimum of each subsystem, multilevel hierarchical control theory is adopted and the vehicle stability coordinated control system including organization, coordination, and execution level is established. Using sliding mode control theory and the inverse tire model, the generalized target forces and moments from organization level are translated into the tire sideslip angle and slip ratio. And then, based on the principle of functional allocation, the control functions of each subsystem are coordinated and the function decoupling of vehicle chassis complex system is realized. The Matlab/Simulink platform is used and the full vehicle stability coordinated control system is simulated. The results show that the full vehicle coordinated control system based on multilevel hierarchical control theory can improve the vehicle stability preferably than the subsystem combined control and uncontrolled system.

Résumé :

In the process of vehicle chassis electrification, different active actuators and systems have been developed and commercialized for improved vehicle dynamic performances. For a vehicle system with actuation redundancy, the integration of individual chassis control systems can provide additional benefits compared to a single ABS/ESC system. This paper describes a Unified Chassis Control (UCC) strategy for enhancing vehicle stability and ride comfort by the coordination of four In-Wheel Drive (IWD), 4-Wheel Independent Steering (4WIS), and Active Suspension Systems (ASS). Desired chassis motion is determined by generalized forces/moment calculated through a high-level sliding mode controller. Based on tire force constraints subject to allocated normal forces, the generalized forces/moment are distributed to the slip and slip angle of each tire by a fixed-point control allocation algorithm. Regarding the uneven road, H∞ robust controllers are proposed based on a modified quarter-car model. Evaluation of the overall system was accomplished by simulation testing with a full-vehicle CarSim model under different scenarios. The conclusion shows that the vertical vibration of the four wheels plays a detrimental role in vehicle stability, and the proposed method can effectively realize the tire force distribution to control the vehicle body attitude and driving stability even in high-demanding scenarios.

Résumé :

Abstract The regenerative braking system of the electric vehicle with the linear control chassis plays an important role in improving the mileage of the vehicle, which mainly solves the problem of large electricity demand for the linear control chassis. After analyzing the structural characteristics of the linear control chassis, the constraints of regenerative braking and the existing regenerative braking control strategies, a new regenerative braking control strategy is proposed, and the control strategy is modified. The regenerative braking control strategy model is established by Simulink / Stateflow, and the braking effect and energy recovery efficiency are verified by changing the initial braking speed. The simulation results show that the strategy can well complete the braking task of the vehicle, and the braking energy recovery rate increases with the increase of the initial braking speed. Reasonable control strategy can effectively improve vehicle energy recovery efficiency.

Résumé :

In order to solve the problems of wheel locking and loss of vehicle control due to understeering or oversteering during the braking energy-recovery process of the hydraulic regenerative braking system (HRBS), aiming at the characteristics of chassis domain control that can realize coordinated work among various chassis systems, a cooperative control strategy of HRBS based on chassis domain control was proposed. Firstly, a HRBS test bench was built, and the accuracy of the simulation model was verified by comparing it with the test. Next, the proposed cooperative control strategy was designed, which coordinates the wheel anti-lock actuation system (WAAS) to adjust the wheel cylinder pressure to solve the wheel locking problem of HRBS in the process of braking energy recovery and coordinate the vehicle anti-loss control actuation system (VACAS) to generate a yaw compensation moment to solve the vehicle loss of the control problem of HRBS in the process of braking energy recovery by detecting the wheel slip ratio, yaw rate and sideslip angle. Finally, the established control strategy was verified through the co-simulation of Carsim and Matlab software, and the results showed that the control strategy proposed in this paper could not only avoid wheel locking and loss of vehicle control during turning braking on low-adhesion roads, but also improve the energy-recovery efficiency by 29.64% compared with a vehicle that only controls the slip ratio.

Résumé :

This paper addresses the problems of structure design and trajectory tracking control of a mobile chassis of life support robots. First, a novel omnidirectional mobile chassis structure is proposed, which consists of three pairs of modular wheel sets with independent drive and steering capability. This allows robots to possess omnidirectional mobility and structural reliability. Then, the trajectory tracking control law is established by combining kinematics analysis and Lyapunov theory. Furthermore, considering the requirement of life support robots to be used under network control, this paper proposes an event-triggered trajectory tracking control scheme to improve the utilization efficiency of communication resources. Finally, the effectiveness of the omnidirectional mobile chassis and the event-triggered control law designed in this paper are demonstrated by numerical simulation results.

Résumé :

An idea of a control system architecture for a new wheeled mobile robot is proposed. The robot construction is characterized by an original drive mechanism and constitutes an extension of the previous research performed in Hochschule Ravensburg-Weingarten. In the new construction, the robot is given the ability to rise or lower its chassis. No complicated additional hardware is required as the level of the chassis can be changed by means of torque differences on the wheels. A modular approach is adopted to develop a hierarchical two-level and layered control system. Low and high levels correspond to local and global vehicle control. The low level is described in more detail, defining the layers and providing appropriate justification.

Résumé :

In order to eliminate the mutual interferences among the differential assist steering system, the active suspension system and the electrical stability control, this paper proposes a sliding mode decoupling control strategy based on the inverse system method for the electric wheel vehicle. The dynamic model of the integrated chassis system is established, and the coupling relationship among the subsystems is analyzed by the correlation analysis. Based on the inverse system method, a compound pseudo linear system is constructed by an inverse system connected in series before the original chassis system, which is linearized and decoupled into three independent linear integral systems. In order to improve the robustness and anti-interference of the decoupled system, a pre-compensation controller based on the sliding mode control is designed for the pseudo linear system. The results of simulation and vehicle test show that the proposed decoupled controller has excellent decoupling performance, which can accomplish the single-channel control of the three decoupled subsystems, and eliminate their influences and interferences. Furthermore, it can effectively track the reference signal and reduce the impact of the external interference, which can obtain an excellent comprehensive performance of the chassis system.

Résumé :

In view of the problems that exist in the working plane of the inspection robot equipped with precision instruments that cannot always maintain a stable state when moving on a complex road surface, a floating mobile chassis was designed based on the Teoriya Resheniya Izobreatatelskikh Zadatch (TRIZ) theory, and the floating suspension device was also optimized based on the substance field. The kinematic model of the floating mobile chassis was established, and the obstacle-surmounting analysis has been carried out on complex road conditions such as the boss and trench. The dynamic model and mobile performance evaluation model of the obstacle crossing wheel are established. The prototype of the non-floating mobile chassis and the prototype of the floating mobile chassis were respectively established in ADAMS, and the motion comparison simulation analysis of boss, trench crossing and complex road conditions were also carried out. The results showed that the floating mobile chassis has strong adaptive performance, and the stability of the working plane can always be maintained when crossing obstacles.

Résumé :

Due to the current unstable travel performance and poor driving maneuverability of rice combine harvester crawler chassis with high load in the rice field, the driver’s standard sitting posture model was developed by analyzing the handling of the crawler chassis driving control panel. Based on this model, the joystick length and cab manipulation space layout were designed. The Finite Element Software was used to develop the loading and restraining model of the chassis frame, and then the structural characteristics and bearing capacity of the crawler chassis were analyzed. The high-bearing running stability and the rationality of operating force of the joystick of rice combine harvester crawler chassis designed in this paper through experiments were verified by experiments. The results showed that when the crawler chassis of rice combine harvester bears a load of 3.5 t, the driving speed is relatively stable in the three speed ranges of 1 m/s, 1.5 m/s, and 2 m/s, and the maximum variance of driving speed variation is 5.022 × 10−4. The actual average operating force of each operating lever on the crawler chassis ranges from 30.36 to 42.71 N, and the operating force of each operating lever is suitable for 95% of Chinese adult male operators. The research results provide a good method and reference for the future development of the crawler chassis structure of rice combine harvester.

Résumé :

In this paper, a supercapacitor control system is designed to improve the motion performance of small unmanned vehicles. The supercapacitor is used as the auxiliary power supply for the chassis of the unmanned vehicle. When working at low power, the lithium battery supplies power to the chassis and charges the supercapacitor. When climbing or accelerating, the supercapacitor is used to assist the power supply to improve the body’s movement ability. The current and voltage values are collected by high-precision sensors and the system charging control is completed by fuzzy PID. It has a good effect on the test, which significantly improves the motion performance of the unmanned vehicle.
