Detailed Description
As shown in fig. 1, which is an embodiment of a switching control system of a two-way vehicle-mounted camera according to the present invention, the switching control system mainly includes a lens unit, a video control unit 2, and a gear signal obtaining unit 4, in addition to a conventional display module, where the display module further includes a display unit 31 and a power supply unit 32 for supplying power to the display unit 31.
The gear signal acquiring unit 4 is mainly used for acquiring vehicle gear signal information, and is connected to the display unit 31 and the video control unit 2 at the same time.
As shown in the figure, the lens unit in turn comprises a first lens unit 11 and a rear view mirror unit 12, the first lens unit 11 being primarily intended to be mounted towards the front of the vehicle, and the rear view mirror unit 12 being primarily intended to be mounted towards the rear of the vehicle. Meanwhile, the first lens unit 11 and the rearview mirror head unit 12 are both connected to the video control unit 2 to transmit the captured image to the video control unit 2.
Preferably, the first lens unit 11 may further include a camera that is changed to another position, and the camera is installed at a different position to acquire a picture required by a vehicle owner, such as a side-view camera; similarly, the rearview mirror head unit 12 may also include a camera that is changed to another position, and the camera is installed at a different position to capture the image required by the vehicle owner. The camera can be flexibly changed, and automatic or manual switching between the lenses is realized.
The video control unit 2 in the system is configured to receive an image frame acquired by the first lens unit 11 or the rearview mirror unit 12, and send a control signal for displaying the image frame acquired by the corresponding lens unit (i.e., the first lens unit 11 or the rearview mirror unit 12) according to the gear signal information provided by the gear signal acquiring unit 4.
As shown in the figure, the video control unit 2 is simultaneously connected to the display unit 31 to send the control signal to the display unit 31, so that the display unit 31 can switch the display picture to display the image picture collected by the corresponding lens unit after receiving the instruction. In addition, the video control unit 2 in this embodiment further includes a timer, which is used to automatically switch back to the normal display picture after the display picture is maintained for a certain preset time after the automatic switching to the display of the image picture collected by the corresponding lens unit is realized.
In this embodiment, a manual switch unit is further provided, and the manual switch unit is connected to the video control unit 2, so that when the front and rear vehicle conditions need to be checked in a non-reversing state, the video control unit 2 can be manually controlled, and the display frame of the display module is further controlled. As shown, the manual switch unit may include an f.view switch 51 and an r.view switch 52, the f.view switch 51 being used to switch the display unit 31 between a normal display screen and an image screen captured by the first lens unit 11, and the r.view switch 52 being used to switch the display unit 31 between a normal display screen and an image screen captured by the rear view lens unit 12.
By using the system structure shown in the above embodiment, the automatic control of the switching of the two-way vehicle-mounted camera can be realized by combining the control method of the present invention, as shown in fig. 2, the specific flow of the automatic control is as follows.
When the display module normally displays the interface, the information of the vehicle gear signal is obtained, whether the gear signal is a high-level reverse signal or not is judged (if the level of a reverse gear R gear is 12V, and other gears are 0V), if the gear signal is not the reverse signal, the normal display interface is maintained, and subsequent steps are not needed.
If the signal is a reversing signal, switching the display picture to an image picture acquired by the rearview mirror head unit; and whether the level of the reversing signal changes or not is continuously monitored, and if the level of the reversing signal does not change, the image picture collected by the rearview mirror head unit is continuously displayed.
If the level of the reverse signal is monitored to be changed, the display picture is switched to the image picture collected by the first lens unit, and after the display picture is kept for the duration time T1 (8 seconds as shown in FIG. 2), the display picture is switched back to the normal display interface.
In addition, when a user needs to check the front and rear vehicle conditions in a non-reversing state, the switching of the display screen can be realized by simple manual switch triggering, as shown in fig. 3-4, and the specific flow of manual control is as follows.
When the display module normally displays the interface, the f.view switch is manually triggered to switch the display interface to the image frame acquired by the first lens unit, and after the display frame is maintained for a duration T2 (120 seconds as shown in fig. 3), the display frame is automatically switched back to the normal display interface.
When the display module displays the interface normally, the r.view switch is triggered manually, the display interface is switched to the image frame collected by the rearview mirror head unit, and after the display frame is maintained for a duration T3 (120 seconds as shown in fig. 4), the display frame is automatically switched back to the normal display interface.
It should be noted that, in the above embodiments, the time periods of T1, T2, and T3 may be set based on the driving experience value of the public or the actual demand of the user, so as to improve the degree of automation control of the vehicle and the driving experience of the user.
