With the impact of electrification and intelligentization of automotive chassis, the brake by wire system has gradually become mainstream, and reliable backup braking control has also become an important component in the development of autonomous driving technology. This paper studies the backup braking control method based on the electronic parking brake actuator. Firstly, the structure and working principle of the electronic parking brake system are analyzed, and a system model is established to reveal the correlation between the braking clamping force and motor current and position. Then, a closed-loop control method based on current and position is proposed for backup braking control. Finally, experimental verification of the backup braking control performance is conducted on a physical test bench, and the robustness under voltage disturbances is tested to verify the feasibility of the backup braking solution.
