- Abstract
To solve the problems of high power consumption and insufficient driving range of pure electric rear-drive commercial vehicle, a braking energy recovery method for the pure electric rear-drive commercial vehicle was proposed. The original H-type hydraulic pipeline layout of the brake system was kept, and the fixed ratio distribution of the front and rear axle hydraulic braking force was unchanged.Only one brake pedal force sensor was added, and the braking energy recovery strategy was proposed based on ECE R13 and I curves. AVL Cruise and Simulink were used to establish a joint simulation platform for vehicle, and a strategic model and a typical series scheme model with greatly increasing costs were built and compared. Under three typical conditions, the vehicle brake energy recycling simulation test was conducted. The results show that the proposed braking energy recovery control strategy with load identification can approach the upper limit of recovery within the safety limit at low cost, and the driving distance can be increased by more than 21.00% compared with the original design at full load.
