Simulator and simulation method for ABS (anti-lock brake system)

摘要

The present invention relates to a real-time ABS simulator and a simulation method, including a master cylinder and a brake system including a pneumatic cylinder and a vacuum pump for generating pressure when the driver depresses the brake, a motor pump for circulating the flow, A solenoid valve for reducing the pressure when the solenoid valve is locked, a relay box for driving the motor pump and the solenoid valve, a pressure measuring device for measuring a braking pressure applied to the front and rear wheels, An A / D converter for converting the vehicle speed into a digital value, a control logic for calculating a wheel speed and a vehicle speed using a predetermined initial speed and the pressure value, and calculating a slip ratio according to the calculated slip rate, A driving logic for driving the relay box to output a simulation result, Comprises a logic contains a personal computer, it may determine the validation and characterization of the hydraulic system of the control logic development.
