碩士 === 國立中興大學 === 電機工程學系所 === 105 === As the science and technology, advanced, electric vehicle technology has been consummate and universal, but the braking system still uses mechanical discs or drum brakes. Although the anti-lock braking system have commonly been used in electric vehicles, however, most vehicles still use traditional hydraulic-based disc brake, and the driving system and braking system are two independent modules in the current vehicle. In this research, an integrated driving and braking control system of the ABS design for electric vehicle with satisfactory braking performance is proposed. When braking, a motor is converted into a generator, which energy can be used to generate reverse magnetic braking torque and to realize an anti-lock braking controller with fast response. Compared with the existing regenerative braking and short circuit braking methods, this research uses the back-EMF to yield reverse magnetic braking torque. It is combined with the capacitor regenerative braking to fulfill an anti-lock braking controller. We use a PID controller to drive the motor. We control the slip ratio to the optimal value by introducing a fuzzy slip ratio controller. For the experimental verification, we have conducted a variety of on-road tests to examine performance of the slip ratio control, compared several tests to verify this method.
