Description

Technical Field

[0001] The present invention belongs to the technical field of automobile electronics, and in particular relates to a vehicle-mounted camera device, a control method thereof, and a vehicle. Background Art

[0002] With the development of the automotive industry, cars are increasingly equipped with panoramic and reverse cameras, and their applications are also expanding. From simple reverse assist systems, a host of new features have gradually emerged, such as pedestrian recognition, blind spot monitoring, and lane departure detection. In-vehicle cameras, typically installed on the front, rear, left, and right sides of a vehicle, can improve driving safety, protect passengers and the vehicle, and enhance traffic safety. Cameras mounted on the front of the vehicle monitor the road ahead and provide features such as forward obstacle warning and adaptive cruise control; cameras mounted on the rear monitor traffic behind and provide reverse imaging; and cameras mounted on the side of the vehicle monitor cross traffic and provide features such as side parking assistance. However, in daily use, car owners often find that the camera lens, due to its design, cannot protrude significantly from the exterior surface, resulting in a limited field of view and an inability to provide a full range of images, leading to false alarms and missed alerts. Summary of the Invention

[0003] The object of the present invention is to provide a vehicle-mounted camera device, a control method thereof, and a vehicle. By applying the control method of the vehicle-mounted camera device, the real-time captured image data is compared with the data in the preset scene image database during the use of the vehicle to determine whether to turn on or off the automatic telescopic rotation function of the camera, and the camera is controlled to automatically extend and rotate in all directions. This solves the problem that the existing car camera cannot protrude too much from the surface due to the limitation of the car body shape and the limited field of view. The camera's shooting range is increased, a panoramic fusion image of the use scene is provided, and a scientific reference basis is provided for the control system's early warning and alarm.

[0004] The specific plan is as follows:

[0005] A vehicle-mounted camera device includes a shell, a camera and a driving mechanism. The driving mechanism is accommodated and connected in the shell, and the front end of the driving mechanism can be rotatably exposed outside the shell, and the front end of the driving mechanism is transmission-connected to the camera. The driving mechanism includes a controller, a motor and a transmission device. The motor is a forward and reverse motor. The transmission device includes a telescopic rotating transmission member and a multi-angle rotating transmission member. The controller is electrically connected to the motor and the multi-angle rotating transmission member. The motor is transmission-connected to the telescopic rotating transmission member. The telescopic rotating transmission member is transmission-connected to the multi-angle rotating transmission member. The multi-angle rotating transmission member is movably connected to the camera. The shell is provided with an opening. The front end of the telescopic rotating transmission member, the multi-angle rotating transmission member and the camera are all exposed outside the opening.

[0006] The vehicle-mounted camera device of the present invention utilizes a worm gear and ball screw transmission structure, coupled with an electric universal joint, to enable a hidden camera mounted on either end of the front or rear bumper or at the front and rear corners of the vehicle body trim panel to freely extend and retract within its mounting holes and rotate in all directions after extending out of the vehicle. This solves the problem of conventional vehicle-mounted cameras, which, due to the vehicle's shape, cannot protrude far beyond the vehicle body, resulting in a narrow field of view, blind spots, missed images, and incorrect images. The control method of the vehicle-mounted camera device of the present invention pre-collects scene image data as samples to form a preset scene image database. The scene image data includes image data for various scenarios, such as high-speed driving, complex road conditions, above-ground parking lots, and underground garages. After the vehicle is started, the camera is activated to capture real-time images. The captured image data is sent to the body control module, which then sends it to the electronic control unit (ECU). The ECU compares the received image data with corresponding scene image data in a preset scene image database. When the comparison result's similarity to the scene for enabling the telescopic rotation function exceeds a threshold (the threshold range is 60%-90%, with a preferred value of 80% in the present invention), the ECU sends a command to the body control module to activate the camera's telescopic rotation function. Upon receiving the command, the body control module sends the telescopic function activation command to the controller of the vehicle-mounted camera device to the motor. The housing of the vehicle-mounted camera device comprises a rectangular accommodating cavity. The drive mechanism is housed and connected within the housing, and the camera is transmission-connected to the drive mechanism. The motor of the drive mechanism is a forward-reversible motor, and the camera's extension and retraction are achieved by changing the motor's rotation direction. The drive mechanism's transmission device includes a telescopic rotation transmission member and a multi-angle rotation transmission member. The drive mechanism's controller is electrically connected to the motor and the multi-angle rotation transmission member. The motor is transmission-connected to the telescopic rotation transmission member, which is transmission-connected to the multi-angle rotation transmission member, which is movably connected to the camera. The housing has an opening, through which the front end of the telescopic transmission, the multi-angle transmission, and the camera are exposed. The worm gear of the telescopic transmission is connected to the motor shaft, and the worm wheel and worm are meshed and connected. The worm wheel is fixed to the rear wall of the housing via two bearing blocks. A rotating shaft is fixedly sleeved within the center hole of the worm wheel. The worm wheel is fixed by the rear end of the rotating shaft being rotatably sleeved within a bearing fixed in a through-hole in the rear wall of the housing. The front end of the rotating shaft has a threaded structure, and the ball screw nut of the connecting assembly is drivenly connected to the threaded structure of the rotating shaft to form a ball screw structure. The ball screw nut moves linearly on the rotating shaft. A displacement stopper is provided at the top of the rotating shaft to prevent the nut from falling out of the rotating shaft. One end of the connecting plate of the connecting assembly is fixedly connected to the ball screw nut, and the two can be integral. The other end of the connecting plate is fixedly connected to the multi-angle transmission, namely the electric universal joint. The other end of the electric universal joint is movably connected to the camera.The controller sends instructions to the motor respectively. The rotation of the motor drives the worm gear assembly to rotate. The connecting shaft rotates along with the worm gear. The ball screw nut drives the connecting plate, the electric universal joint and the camera to make a linear motion along the connecting shaft toward the outside of the vehicle and extend out of the camera's mounting hole. After the camera extends out of the mounting hole, the controller sends a rotation instruction to the electric universal joint. The electric universal joint rotates according to the rotation speed and angle of the instruction and drives the camera to make a full-scale rotation. Compared with the existing telescopic rotating camera, the vehicle-mounted camera of the present invention has a simple structure and is easy to operate. The camera automatically turns on or off the telescopic rotation function when needed. It is convenient and fast, expands the camera's shooting field of view, increases the clarity and accuracy of real-time image data, avoids monitoring blind spots, and can provide a more reliable, comprehensive and scientific image judgment basis for the electronic control unit analysis and alarm.

[0007] When the image data captured by the camera in real time is compared with the scene image data of the preset scene image database with the telescopic and rotation function of the camera turned off, and the similarity is higher than the threshold, the threshold range is 60%-90%, and the preferred value of the present invention is 80%, the electronic control unit sends a shutdown command to the body control module, the body control module sends a command to the controller, the controller sends a command to the electric universal joint to stop rotating, and the controller then sends a command to the motor. The motor of the present invention is a forward and reverse motor. When the motor reverses, the worm gear rotates in the opposite direction and drives the rotating shaft to rotate in the opposite direction. The nut rotates in the opposite direction and makes a linear motion along the rotating shaft in the direction of the worm gear and drives the connecting plate, the electric universal joint and the camera to be retracted into the mounting hole.

[0008] The vehicle-mounted camera control method of the present invention can automatically turn on or off the telescopic and rotating functions to meet shooting needs, which is simple, convenient, accurate, and efficient. Compared with existing vehicle-mounted cameras, the vehicle-mounted camera device and its control method of the present invention have a simple structure, easy operation, and a wider shooting field of view.
