The invention discloses an automobile electric sliding door system. The automobile electric sliding door system includes a starting switch, a controller, an automobile door motor, a Hall sensor and adoor lock; the controller is connected with the starting switch, the automobile door motor, the Hall sensor and the door lock separately, the starting switch initiates a door opening signal, after thecontroller receives the signal, the signal is transmitted to the Hall sensor, the Hall sensor judges the position state of an automobile electric sliding door and feeds back the signal to the controller, and after receiving the signal fed back by the Hall sensor, the controller controls the automobile door motor to start or not. According to the automobile electric sliding door system, by converting a traditional manual sliding door into the automobile electric sliding door, the automobile electric sliding door is protected; currently, the traditional manual sliding door is opened and closedmanually and thus is easily collided and damaged, and accordingly the service life of an automobile is influenced; the door lock is controlled by a controller, so that an automatic door locking function is achieved; the automobile electric sliding door has a clamping prevention function and thus is safer than the traditional manual sliding door, and a full automation effect is achieved.
