英文摘要： The key techniques of vehicle dynamics control based on brake-by-wire will be researched. Using bench test and computer simulation, the brake control rules of ABS, TCS and YSC, the algorithms of brake torque increase and decrease, and the associated mechanism of engine, transmission and brake-by-wire will be determined, considering such factors as response velocity, handling and stability, and braking (or accelerating) performance. The development system will be developed to implement real-time data acquisition, memorizing, on-line debugging and multi-ECU communicating, and on-line sensor system. The brake-by-wire motors will be made to meet demands of driver's braking intention and response velocity. The vehicle dynamics simulation software will be upgraded for the research of vehicle dynamics control based on brake-by-wire. After that, the previous test bench will be reconstructed to be the hardware and software-in-the-loop bench, which comprises dynamics simulation software, on-line sensor system, motor braking actuator, and controller (or prototype). Finally, the test matching and evaluation of control system will be done. It is of great significance to master key techniques of the vehicle dynamics control based on new generation of automotive brake system to carry out the project.
