Capacity Allocation of Driving System and Braking System for Distributed Drive Electric Vehicle

To solve the problem that the mainstream capacity allocation method of driving and braking systems for distributed drive electric vehicles adopts uniform distribution among four wheels, a novel capacity allocation method of driving system and braking system is proposed. Among them, the capacity allocation of driving system for power performance is to improve the maximum acceleration, the maximum gradability, and the 0–100 km/h acceleration time; the capacity allocation method of electro-hydraulic braking system for braking performance is to improve the braking distance and the average braking deceleration. The results of the theoretical analysis indicate that the proposed capacity allocation method effectively improves the power performance and braking performance of the vehicle.
