Research On ABS Dynamic Performance Test Bed

Through this subject on the current performance of the domestic ABS test-bed system of the status quo; view of the current teaching and scientific test-bed system is flawed, the analysis of their predecessors in the Electrical and Mechanical mixed simulation technology on the basis of the work done, put the car inertia and The Electrical and Mechanical simulation of ground-force theory. On the car of inertia and ground-force of the principle of the Electrical and Mechanical Simulation(1) According to ABS car performance test of the necessary and the ideal test-bed design, four-wheel modules, the single wheel in the structure of the same module, the measurement and control of mutual independence, the modules share the same Control system, can achieve different brake early speed and different road conditions, ABS brake when the simulation process.(2) According to an automotive technology company's specific design requirements, "MARK-â…¡ABS control system" and the company's "Qianpanhougu braking system platform" for the research, design and create a new dynamic performance ABS Test bench.(3) the use of computer monitoring and control technologies, the establishment of a dynamic performance test ABS computer monitoring system, to achieve the three-phase asynchronous motor with incremental PID controller of the closed-loop control and Frequency Control of the magnetic clutch of open-loop control torque transfer . (4) the use of virtual instrument technology and computer programming technology, simulation tests to work under ABS vehicle speed and wheel speed change as the goal, the design of the entire system of monitoring and control software program.(5) developed a new type of ABS dynamic performance test bed for the platform, design a variety of different speed with different terrain vehicle ABS pilot programme, and a large number of experimental verification.After the commissioning of this pilot system was tested, and from the vehicle speed, wheel speed rear axle of the curve, the system basically achieved the goal of the design, compared to the real beginning of the simulation at different speeds and different road conditions (different ? ) system Dynamic, ABS play a role when the vehicle braking process.
