The invention discloses a high-voltage relay control system and method and an automobile. The system comprises a main control device, a driving device and a high-voltage relay. The main control device comprises an MCU controller, a cache unit and a self-locking unit, and is used for receiving feedback signals input by other modules in the control system and a high-voltage control instruction of a whole automobile system and sending the feedback signals to the driving device; the high-voltage relay is controlled through the cache unit, the main control device can lock a power supply access of the cache unit through the self-locking unit during the abnormal reset period of the MCU controller, the control over the high-voltage relay is kept through the cache unit, and the driving device is used for driving the high-voltage relay to be closed or opened so as to connect or disconnect a power supply path of a high-voltage battery system to a load. According to the control method, under the condition that the system is abnormally reset, the high-voltage relay is kept to be closed, the situation that the automobile loses power due to sudden high-voltage cut-off is avoided, and the driving safety of the automobile is improved.
