Abstract


In recent years , due to the rising rate of accidents caused by the heavy-duty vehicles , often causing heavy casualties . Thus , from technology tools to enhance the multiaxial vehicle safety performance is an urgent problem . The main purpose of this thesis is to improve vehicle braking performance and low adhesion coefficient road starting with vehicle performance , improve active safety , reduce the rate of traffic accidents . Through the establishment of multi-axis load vehicles model to study the driving force of the multi-axis vehicle control system , control methods and control strategies to build semi - physical simulation of the ABS / ASR control system development platform in order to improve the safety performance of the vehicle . First of all , through the establishment of the model of the the multiaxial vehicle (6X4) , the application of Newtonian principles of mechanics and multi-body dynamics principle vehicle Matlab / Simulink model and Adams model , the use of ultra-quiet courage of your convictions principle and the principle of energy axle load stress analysis , and the introduction of the deformation coordination theory correct axle load calculation to simulate the longitudinal movement and rotation of the wheels of the vehicle , power , handling and braking of the vehicle dynamics , the ideal vehicle simulation exercise effect . Secondly, the ABS / ASR control system model , focusing on the establishment of threshold logic control model and PID control model to study after parameter optimization and restructuring , connected vehicle model for real-time simulation to verify the control algorithm and control strategies , the research vehicle the driving force control of key technical issues . The simulation results show that the control module controls effect the desired effect . Finally , build the hardware in the loop simulation control system development platform as the core to the DSP high-performance chip design semi - physical simulation of vehicle driving force control system structure , software module design ideas and software processes by the hardware emulator CCS integrated development environment and the actual hardware development platform communicates via Matlab CCS link tool the CCS IDE ABS / ASR control system with real - time communication , to complete the semi- physical simulation system .
