Brake performance is the main vehicle of security, it relates to driving safety. Vehicle braking performance indicators are the most basic brake deceleration, stopping distance, time and directional stability, braking when the car is able to track the direction of travel specified.
If the vehicle's emergency brake of vehicles locked, it is very dangerous, if the front wheel locked, will allow cars to lose steering capabilities; If the rear wheel locked, there will be a drift or sliding, especially in slippery road surface situations, and cause great harm to traffic safety.
Therefore, this paper is to car anti-lock braking system used in YAMAHA YP250A heavy locomotive to achieve with the car's braking effect is the same, in addition to collecting information, this research into the system architecture, component characteristics and dynamic model analysis and design, another focus is the overall system model, write MATLAB/SIMULINK programming, simulation, and verify the accuracy of vehicle ABS as a design analysis tool; Different speed 30km/hr, 60km/hr and 100km/hr, the analog wheel speed brake, body speed brake, body stopping distance, brake slip ratio changes, solenoid valve response and body deceleration value. In this study, another road dynamic test, the time of actuation of about one and a half or so, the speed is about 21km/hr in a DSP hardware architecture, the front and rear wheel brake control system to operate independently and separately from the software implementation, the front wheel speed, rear wheel speed, front wheel chaises, rear wheel chaises and slip ratio data, then use the MATLAB / SIMULINK simulation of the slide than the deployment is over 0.2, compared with more than 0.2 if the slide valve opens once the operation to verify the design of the ABS system in this study than the more than 0.2 in the slip-loop control by the control back to 0.2, the known presented results are in line with the actual desired results.
