AI Technical Summary
Technical Problem
Existing electric vehicle braking systems are prone to loss of control when the electronic control unit malfunctions, resulting in insufficient safety, especially at high speeds where there is a high risk of center of gravity shift and rollover.
Method used
It adopts a dual control structure of "electromagnetic actuator + mechanical clutch", and achieves rapid interruption of power transmission through clutch components and anti-runaway mechanism to avoid failure of single control method.
Benefits of technology
In the event of brake failure and electronic controller malfunction, it can quickly cut off power transmission, significantly improving safety in extreme scenarios and preventing vehicle loss of control.
