Space Limitation

This paper presents an active safety device for skid control of small electric vehicles with in-wheel motors. Due to the space limitation on the driving tire, a mechanical brake system was installed rather than hydraulic brake system. For the same reason, anti-lock brake system (ABS) that is a basic skid control method cannot be installed on the driving tire. During braking on icy road or emergency braking, the tire will be locked and the vehicle is skidding. To prevent tire lock-up and vehicle from skidding, we proposed the combination of ABS and regenerative brake timing control. The hydraulic unit of ABS is installed on the non-driving tire while the in-wheel motors on the driving tire will be an actuator of ABS to control the regenerative braking force. The performance of the ABS and regenerative brake timing control on the emergency braking situation is measured by the simulation. The simulation result shows that the combination of ABS and regenerative brake timing control can prevent tire lock-up and vehicle from skidding.

Braking Control

The introduction of driving motors brings in the function of regenerative braking for Hybrid Electric Vehicles (HEV). In order to study the further information of regenerative braking, the relation between the degree of mixing in HEV and the recovery rate of regenerative braking was analyzed. The study object was the front-wheel driving HEV with the wire-control composite regenerative braking control strategy. Conclusions were deduced through the theoretical derivation. The braking model was established on the platform in MATLAB/SIMULINK and it was simulated within a HEV. The results indicate that the recovery rate would increase if the degree of mixing rises.

Braking Control

A brake pedal stroke simulator is a key component of realizing a Regenerative Braking System. It provides a good pedal feeling to a driver, improves energy recovery and ensures braking security. This paper presents the hardware solution of the braking control system, the structure and key design parameters of a brake pedal stroke simulator. Through simulation, the energy recover rate and brake pedal feeling of drivers can be improved. The simulator can be used to realize the regenerative braking system in hybrid or electric vehicles.

Braking Energy Recovery

The battery ability of recovering electricity plays a significant role in improving the regenerative braking performance. In this paper, a control for recovery of braking energy in Electric Vehicles (EVs) with electro hydraulic brake (EHB) is proposed, which makes the recovery transfer to the electric hydraulic pump of EHB directly, rather than being stored statically in the battery. An energy flow strategy was designed for the maximum braking energy recovery based on this control. The simulation results show higher energy recovery rate in comparison to the general recycling control.

Braking Energy Recovery

In order to improve the recovery of braking energy in electric vehicles, a braking force distribution control strategy is proposed which the braking force proportion of the front and rear wheels are distributed according to the brake strength, by analyzing the vehicle braking mechanics and related braking regulation, and combining with the motor output characteristics. A simulation is carried out with SIMULINK/ADVISOR, the results show that, comparing with ADVISOR braking force distribution control strategy, the control strategy not only meets braking stability well，but also there are obvious advantages in energy consumption per 100 kilometers，the rate of braking energy recovery and utilization.
