A vehicle-mounted device for realizing the control method of the vehicle-mounted camera described in any one of Claims 1 to 9, the improvement is that the vehicle-mounted device includes: Vehicle-mounted camera, used to provide driving environment images; The memory stores computer programs and a high-precision map module, and the high-precision map module obtains road information; Sensors for detecting the distance between the vehicle and nearby objects; A processor, the processor is used to execute the computer program in the memory: Obtaining road information and judging whether the road information satisfies a preset condition for opening; When the road information satisfies the preset opening condition, the on-board camera is turned on; When the road information does not satisfy the opening preset condition, 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 condition preset conditions; When the distance between the vehicle and the adjacent object satisfies the preset condition for opening, the on-board camera is turned on; After the on-board camera is turned on, detect the distance between the vehicle and the adjacent object and judge whether the distance between the vehicle and the adjacent object meets the preset condition for closing; When the distance between the vehicle and the adjacent object satisfies the preset shutdown condition, the vehicle camera is turned off.
