| description | The invention relates to a driving brake redundancy control method and system for a low-speed functional drive-by-wire vehicle, and the method comprises the steps: C1, obtaining the braking deceleration data information of the vehicle in real time based on a vehicle AD controller when the vehicle runs on a road; c2, real-time vehicle deceleration is obtained based on the vehicle braking deceleration data information, if the real-time vehicle braking deceleration is equal to zero, the vehicle control unit periodically sends an EMB release instruction message to an EMB controller, and an EMB actuator is made to be in a release state; and C3, if the real-time vehicle braking deceleration is larger than zero and smaller than the maximum braking deceleration, the vehicle control unit sends a braking instruction to the MCU through a Lagrange interpolation algorithm, and the MCU controls a driving motor to brake. The safety of vehicle driving can be guaranteed, the braking process is more intelligent and smoother, a |
