A co-simulation platform for ICC (Integrated Chassis Control) system was built under the MATLAB and AMEsim environment. A vehicle dynamic model was developed using the MATLAB software, and a dynamic response model for hydraulic brake system was built using the AMESim software. Then, the data exchanged through the AMEsim special interface module and the MATLAB S-function. The co-simulation platform...
System modeling and computer aided simulation have been increasingly used in vehicle engineering to reduce development time, improve and simplify complex systems. A Type C Electronic Power Steering (EPS) modeling and simulation program has been developed based on Matlab. The aim of this simulation is to simulate completed system dynamic behavior regarding optimizing main parameters of system model.
In this paper a method of designing the rule bases of fuzzy controllers for Wheel Slide Protection Systems (WSP) for rail vehicles is presented. In this method results of simulation of two reference controllers are used, both of which use signals which are nor available during normal operation of the systems, i.e. adhesion coefficient and translation velocity of the vehicle. Simulations have performed...
Based on research of the phase plane division control method, according to the structure of wheel loader steer by wire system and its work condition, the fuzzy five states control system specially designed for wheel loader steer by wire system is introduced in this paper. To verify its performance, the controller was simulated in MATLAB/SIMULINK based on the model of wheel loader steer by wire system...
Electric Power Steering (EPS) systems have many merits over traditional hydraulic power steering systems in fuel economy, variable assist capabilities and favorable road feeling by virtue of adjustment assist characteristic with adopting assist motor in replacement of hydraulic pump. This paper aims at modeling the mechanical parts, the assist motor and electronic control unit by bond graph technique...
This paper presents a detailed control system building process for a hardware-in-loop micro-satellite simulator to apply and test system identification or control algorithms. It also designs a new system mechanism to combine the simulator with MATLAB Simulink by DDE, which can enable Simulink to directly control the simulator system and accomplish data sharing and real-time control function. Finally,...
Electric Power Steering (EPS) has important significance in improving the auto's dynamic and static performances. This paper deals with the mathematical model and characteristic curves of EPS System. First, the principle and structure of EPS are discussed. Then the characteristics of EPS system are analyzed, including the typical power curves which deal the relationship of the assist torque and the...
The development of advanced vehicle control systems such as ABS, TCS and ESP, depend upon the information about tire-road force, which can not be measured directly in modern cars. A model-based estimation methodology of the tire-road force using a sliding model observer is proposed in this paper. Hyperbolic tangent function is chosen to cover chattering effects of observer. A simulation platform which...
Based on the analysis of the steering performance, the objective of this paper is to present evidence for the tractor adopted the four-wheel steering (4WS) which can improve the handling and stability of tractor semi-trailer. The simplified single track model with 3 DOF for 4WS tractor semi-trailer has been constructed for dynamic simulation through time-domain response on the two states of small...
This paper presents the ground work prepared for turning a bucket wheel reclaimer (BWR) into a robotic arm for operation automation. BWR has been widely used in dealing with bulk materials by removing them from the conveyor and stack them as well as to load stacked materials onto the in-feed conveyor, such as in mining industry. Generally speaking, current BWRs are manually operated, remotely operated,...
