An in-vehicle device for implementing the control method for an in-vehicle camera according to any one of claims 1 to 9, the improvement is that the in-vehicle device comprises: Vehicle-mounted camera, used to provide driving surround image; a memory, which stores a computer program and a high-precision map module, and the high-precision map module obtains road information; Sensors to detect the distance between the vehicle and nearby objects; a processor for executing computer programs in the memory: Acquiring road information and judging whether the road information meets the preset conditions for opening; When the road information meets the opening preset condition, turn on the vehicle camera; When the road information does not meet the opening preset conditions, detect the distance between the vehicle and the adjacent object and determine the distance between the vehicle and the adjacent object, and determine whether the distance between the vehicle and the adjacent object satisfies the opening preset conditions; When the distance between the vehicle and the nearby object meets the opening preset condition, turn on the vehicle-mounted camera; After turning on the on-board camera, detect the distance between the vehicle and the adjacent object and determine whether the distance between the vehicle and the adjacent object meets the preset condition for closing; When the distance between the vehicle and an adjacent object satisfies the shutdown preset condition, the vehicle-mounted camera is turned off.
