摘要
An ideal braking force distribution strategy based on curve I is designed for a two-axle two motor 4WD electric vehicle. With the strategy, the braking forces of front and rear axles are distributed as per I-curve during braking, and both front and rear motors recover braking energy, taking its potential of braking energy recovery while assuring braking stability. The results of simulation show that the strategy can recover more energy with a braking force distribution pattern well agreeing with I-curve, and ensure braking stability, demonstrating its good effectiveness.
