Design and Analysis of Braking Intensity Control Based on Fuzzy Identification for Electric Vehicle
In order to improve the control accuracy of electric vehicle braking intensity,a fuzzy identification braking intensity control method is designed.Combined with the braking intensity under different road adhesion co-efficients,the switching process of braking mode is realized,and the simulation analysis of braking and turning conditions on the open road is carried out.The simulation results show that the braking time can be kept within the safe interval under this strength.The left and right side wheels maintain the same braking force,but the slip rate is significantly different.According to braking simulation in turning conditions,the front wheel steering angle contin-ues to rise and reaches 15° around 3s,and then maintains a stable 15° steering angle.By reducing the slip rate and braking force of the left rear wheel,the actual yaw velocity of the target is obtained.
