A redundant electromechanical braking control system and control method

Abstract

This invention provides a redundant electromechanical braking control system and method. Through multiple redundancy designs, the safety and reliability of the braking system are significantly improved: by setting up dual control links using both electrical communication and hard-wired signals, dual protection of control signals is achieved, effectively avoiding system failure caused by single-point faults. Intelligent arbitration and seamless switching: The motor control unit can monitor control commands from the EMB system main controller and the second vehicle control unit in real time, and under normal circumstances, prioritizes executing the main controller's commands; when a CAN communication anomaly or timeout is detected, it can quickly switch to the hard-wired signal control mode to ensure uninterrupted braking function and improve the system's fault tolerance. Dual-mode hard-wired signal scheme: Two level signal schemes are provided, which can be flexibly configured according to different vehicle models and safety requirements. It also has a signal validity verification function to identify fault states such as signal loss and continuous abnormalities, enhancing the system's environmental adaptability.
