Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, an apparatus 100 for automatically identifying different configurations of a reverse image according to an embodiment of the present invention includes: an in-vehicle entertainment system module 30, a body control module 10, and a reverse image module 20.
The vehicle body control module 10 can send first message information when the vehicle is unlocked; when the image module 20 for backing a car is a panoramic image module, second message information can be generated according to the first message information and sent to the vehicle-mounted entertainment system module 30;
the vehicle-mounted entertainment system module 30 determines whether the reverse image module 20 is a panoramic image module or a rear-view image module according to whether the second message information can be received or not, and performs corresponding configuration and setting.
Therefore, according to the device 100 for automatically identifying different configurations of the reverse image in the embodiment of the present invention, since the vehicle body control module 10 can send the first message information when the vehicle is unlocked, and when the reverse image module 20 is a panoramic image module, the second message information can be generated according to the first message information and sent to the in-vehicle entertainment system module 30. Therefore, the vehicle-mounted entertainment system module 30 can determine whether the reverse image module 20 is a panoramic image module or a rearview image module according to whether the second message information can be received, thereby realizing automatic identification of image display with different configurations, effectively avoiding manual configuration errors, avoiding functional check after the whole vehicle is off-line, reducing the control difficulty of parts, and improving the control capability of the whole vehicle module and the production efficiency of the whole vehicle.
According to some embodiments of the present invention, the step of the in-vehicle entertainment system module 30 determining whether the reverse image module 20 is a panoramic image module or a rear-view image module and performing corresponding configuration setting according to whether the second message information can be received includes: when the vehicle-mounted entertainment system module 30 receives the second message information within a preset time (e.g., 2 seconds), it is determined that the car-backing image module 20 is a panoramic image module and a panoramic image configuration setting is performed; and when the vehicle-mounted entertainment system module 30 does not receive the message information within the preset time, judging that the reversing image module 20 is a rearview image module and setting the rearview image configuration.
Specifically, the vehicle-mounted entertainment system module 30 and the reverse image module 20 may be connected to the vehicle body control module 10 through a CAN bus, and the first message information and the second message information are both CAN messages. That is, the in-vehicle entertainment system module 30 may determine whether the back-up image module 20 is a panoramic image module or a rear-view image module according to whether the CAN message from the back-up image module 20 CAN be received.
According to still other embodiments of the present invention, the apparatus 100 for automatically identifying different configurations of reverse images further comprises an image display request module, which sends a request message to the in-vehicle entertainment system module 30 to display the reverse images.
According to some embodiments of the invention, the image display request module is connected to a reverse gear.
According to some embodiments of the present invention, the reverse image module 20 and the in-vehicle entertainment system module 30 are connected through a CVBS transmission line.
As shown in fig. 2, the method for automatically identifying different configurations of a reverse image according to an embodiment of the present invention includes the following steps:
step S10, the vehicle body control module sends first message information when the vehicle is unlocked, and when the backing image module is a panoramic image module, second message information is generated according to the first message information and sent to the vehicle-mounted entertainment system module;
and step S20, the vehicle-mounted entertainment system module judges whether the backing image module is a panoramic image module or a rearview image module according to the fact whether the second message information can be received or not and carries out corresponding configuration and setting.
Further, in step S20, when the vehicle-mounted entertainment system module receives the second message information within a preset time (e.g., within 2 seconds), it is determined that the vehicle-mounted entertainment system module is a panoramic image module and performs a panoramic image configuration setting, and when the vehicle-mounted entertainment system module does not receive the second message information within the preset time, it is determined that the vehicle-mounted entertainment system module is a rear-view image module and performs a rear-view image configuration setting.
According to some embodiments of the invention, the method for automatically identifying different configurations of the reverse image further comprises step S30, where the image display request module sends a request message to the in-vehicle entertainment system module to display the reverse image.
For example, as shown in fig. 3, the in-vehicle entertainment system module and the panoramic image module have a CAN network wake-up function, when the user unlocks the vehicle, the vehicle body control module wakes up the in-vehicle entertainment system module and the panoramic image module in a CAN message manner, the entertainment system control Module (MCU) detects whether the CAN message of the panoramic image module is received within 2s (the preset time CAN be adjusted as needed) after the initialization is completed (the initialization time is generally within 300 ms), if the CAN message of the panoramic image module is received, the entertainment system module performs configuration setting of the panoramic image module, and if the CAN message of the panoramic image module is not received within 2s, the entertainment system performs configuration setting of the rear view image. When the entertainment system receives a request for displaying images (such as reverse gear), the entertainment system module calls a corresponding human-computer interaction interface according to the set state information and displays the corresponding human-computer interaction interface on a display screen of the entertainment system.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
