Description

Technical Field

[0001] The utility model relates to the technical field of assisted driving, in particular to a camera applied to assisted driving. Background Art

[0002] Assisted driving refers to providing auxiliary support during the process of a driver driving a vehicle, enabling the driver to drive the vehicle on the road more easily and safely. Lane keeping assist systems, auxiliary driving systems, and automatic parking assist systems are all for assisted driving. In the assisted driving system, driving assistance and lane keeping assist systems are particularly important. Existing assisted driving systems mostly identify pedestrians, obstacles, and road markings through cameras and lidar. The camera is used to obtain the front view of the vehicle. When following a vehicle, the lidar works, emitting laser beams to detect the state of the vehicle in front, the vehicle distance, and the presence of pedestrians and obstacles. When the camera and lidar identify that the vehicle deviates from the lane or there are pedestrians and obstacles ahead, they remind the driver or intervene in the steering system to adjust the driving route in time. The position of the camera in the traditional assisted driving system is fixed, and it can only obtain a partial view in front of the vehicle. When the driving state of the vehicle in front changes or the vehicle turns, there is an A-pillar blind area for the vehicle. The fixed camera cannot timely obtain the side view of the vehicle and issue a warning, posing a safety hazard. For this reason, we propose a camera applied to assisted driving.

The limiting grooves (44) are all arranged in the middle of the rear ends of the moving pieces (42). The limiting grooves (44) are groove bodies deflected outward on the front side. A limiting block (45) is slidably connected between the two limiting grooves (44) through a limiting column, providing a basis for the adjustment of the field of view. The adjusting mechanism (4) further includes an auxiliary camera (46). The auxiliary cameras (46) are all arranged at the upper ends of the rotating shafts (3). The auxiliary cameras (46) are bidirectionally electrically connected to the single-chip microcomputer (7), and can quickly obtain the field of view on the side of the vehicle. The adjusting mechanism (4) further includes a driving component (47). The driving component (47) includes a lead screw (471) and a motor (472). The lead screw (471) is rotatably connected to the middle of the upper end of the bottom plate (2). The outer surface of the lead screw (471) is threadedly connected to the middle of the inside of the limiting block (45). The input end of the motor (472) is electrically connected to the output end of the single-chip microcomputer (7). The front end of the output shaft of the motor (472) is fixedly connected to the rear end of the lead screw (471), providing stable drive for the angle adjustment of the auxiliary camera (46). The adjusting mechanism (4) further includes a lidar (48). The lidar (48) is arranged in the middle of the front side of the upper end of the bottom plate (2). The lidar (48) is bidirectionally electrically connected to the single-chip microcomputer (7), and can quickly detect the distance, state of the vehicle in front and obstacles. The adjusting mechanism (4) further includes a main camera (49). The main camera (49) is arranged at the front end inside the housing (1). The main camera (49) is bidirectionally electrically connected to the single-chip microcomputer (7), and can quickly identify the obstacles and road marking lines on the front side. It also includes a Bluetooth transceiver (5). The Bluetooth transceiver (5) is arranged on the right side of the rear end of the housing (1). The Bluetooth transceiver (5) is bidirectionally electrically connected to the single-chip microcomputer (7), facilitating connection to the vehicle central control and quickly transmitting information. There is an auxiliary camera with a variable angle. When the driving state of the vehicle in front changes or the vehicle turns, the two auxiliary cameras deflect outward at the same time, obtaining a larger field of view area, being able to discover, identify the situation more quickly and issue a warning, reducing the occurrence of potential safety hazards caused by the blind spot of the field of view.

[0024] The working principle of a camera applied to assisted driving provided by the present utility model is as follows: During the driving process of the vehicle, the single-chip microcomputer (7) controls the Bluetooth transceiver (5) to work, so that the Bluetooth transceiver (5) is connected to the vehicle central control. At this time, the single-chip microcomputer (7) controls the main camera (49) and the lidar (48) to work. The main camera (49) continuously obtains the field of view in front of the vehicle and sends it to the single-chip microcomputer (7). The single-chip microcomputer (7) identifies pedestrians, obstacles and road marking lines to keep the vehicle on the correct driving route. At the same time, the lidar (48) works, and detects the distance to the vehicle in front, the driving state, and whether there are obstacles and pedestrians by continuously emitting laser beams to ensure the driving safety of the vehicle. When the single-chip microcomputer (7) identifies that the vehicle is deviated, the distance to the vehicle in front becomes smaller, and there are obstacles or pedestrians, it can quickly send an electrical signal to the vehicle central control through the Bluetooth transceiver (5) to control the driving state of the vehicle and issue a warning to remind the driver. When the driving state of the vehicle in front changes or the vehicle turns, the single-chip microcomputer (7) controls the motor (472) to operate. The output shaft of the motor (472) drives the lead screw (471) to rotate, and the limit block (45) also moves forward accordingly. By continuously squeezing the moving piece (42) through the limit post, the two moving pieces (42) move inward synchronously, and the rack plate (43) also moves inward synchronously. Because the longitudinally adjacent gears (41) are meshed with the rack plate (43), as the rack plate (43) moves, the gears (41) also rotate synchronously, driving the rotating shaft (3) to rotate, and the two auxiliary cameras (46) deflect outward simultaneously, and the obtained field of view becomes larger. At this time, the single-chip microcomputer (7) processes the images obtained by the auxiliary cameras (46) and transmits them to the central control screen through the Bluetooth transceiver (5), so that the driver can quickly see the field of view blocked by the vehicle A-pillar through the central control screen. At the same time, the single-chip microcomputer (7) analyzes the obtained images to identify whether there are pedestrians and obstacles in front. When there is a potential safety hazard, it quickly sends an electrical signal to the vehicle central control through the Bluetooth transceiver (5) to control the driving state of the vehicle and issue a warning to remind the driver, effectively avoiding the occurrence of safety hazards caused by the blind spot of the field of view.

[0025] It should be noted that in the above embodiments, the single-chip microcomputer (7) disclosed is an S7-200 single-chip microcomputer, the motor (472) is a DS-380SH-3270 motor, the lidar (48) is an HPS-3D640 lidar, both the auxiliary camera (46) and the main camera (49) are JD-OV2710-V1 cameras, and the Bluetooth transceiver (5) is a CC2541F256RHAR Bluetooth transceiver. The single-chip microcomputer (7) controls the auxiliary camera (46), the motor (472), the lidar (48), the main camera (49) and the Bluetooth transceiver (5) to work using common methods in the prior art.
