Engine exhaust braking control method and device and storage medium

The invention provides an engine exhaust braking control method and device and a storage medium, and relates to the technical field of commercial trucks. According to the method, vehicle state information collected by a sensor is obtained through an engine controller, the vehicle state information comprises a brake pedal signal, the accelerator opening degree and the engine rotating speed, and whether braking control information is generated or not is determined according to the vehicle state information; the brake control information comprises exhaust brake linkage activation information and/or engine protection activation information, and after the brake control information is generated, the brake control information is sent to an engine controller, so that the engine controller controls an exhaust brake execution mechanism to act according to the brake control information to reduce the rotating speed of an engine, and the engine is protected. Therefore, the engine exhaust braking control method can meet th
