Embodiment Construction

[0029] The invention proposes a composite braking system applied to electric vehicles. The braking system integrates electric vehicle motor regenerative braking, electromagnetic braking and band braking. By setting the braking control strategy reasonably, it can not only reduce the The wear of the friction block can reduce the braking noise and heat, and it can realize the anti-lock braking function of the conventional automobile hydraulic braking system, so as to improve the driving safety of the electric vehicle. According to the actual operating state of the electric vehicle, it cooperates with the three-stage brake pedal for real-time control, realizing the driver's driving intention and recovering braking energy.

[0030] The drive motor of the electric vehicle in the present invention selects the hub motor 1, and when the motor regeneratively brakes, the hub motor 1 is used as a generator to recover energy, thereby generating electromagnetic braking force. The electromag...

Abstract

The invention discloses a composite anti-lock brake system for an electric automobile and a brake control method. The composite anti-lock brake system integrates the electric automobile motor regeneration brake, electromagnetic brake and belt type brake. The brake system carries out real-time control through being matched with a three-section type brake pedal according to the actual operation state of the electric automobile in the work sequence of the motor regeneration brake, the electromagnetic brake and the belt type brake, the automobile speed and the speed deceleration of the electric automobile are controlled, the running safety of the electric automobile is ensured, the driving intention of a driver is realized, and in addition, the brake energy recovery can be realized. Through the reasonable setting of the brake control method, the abrasion of a brake friction block can be reduced, the brake noise and the heat can be reduced, in addition, the brake anti-lock function of a conventional automobile brake system can be realized, and the running safety of the electric automobile is improved.

Description

technical field [0001] The invention relates to a composite braking system for electric vehicles, in particular to a composite braking system integrating electric vehicle regenerative braking, drum electromagnetic braking and stepping motor band braking. technical background [0002] At present, the low-speed electric vehicles produced in my country mainly use the disc hydraulic braking system to reduce the speed and stop the vehicle. Some models also have a braking energy recovery system, which achieves the purpose of deceleration / stopping through the electric braking of the motor. The hydraulic ABS system can effectively improve the braking safety of vehicles, and has been widely used in conventional energy vehicles. However, in view of the complex structure and lagging response of the hydraulic ABS system, and its hydraulic pipeline has high requirements for sealing, it is not very suitable for electric vehicles. Contents of the invention [0003] In order to solve the...
