Test Bench Emulation of Slip Ratio during Anti-Lock Braking of Electric Vehicle

Abstract:

Regenerative brakes offer the opportunity to improve a vehicle’s braking performance in emergency situation. This study investigates slip ratio emulation on a test bench to enable these issues to be studied in a lab. Compared with vehicle drive cycle emulation on a test bench, the slip ratio emulation on a test bench requires higher bandwidth because of the higher dynamic requirement of slip control than that of vehicle energy management. Toward this end, a feedforward compensation method that could also prevent the amplification of the noise from the sensor is designed for this based on a linearized wheel slip equation. The results of simulations and tests indicate that the proposed slip-ratio emulation method can emulate the dynamic variation of the slip rate effectively.
