Vehicle-mounted information display screen driving auxiliary video display system and method

Abstract

The invention provides a vehicle-mounted information display screen driving auxiliary video display system and method. The system is characterized in that a reversing image connector and a video connector in the system are both connected with a driving auxiliary display screen, and an environment image controller and a right blind area controller are correspondingly connected with the video connector. The method comprises the following steps: after a driving auxiliary display screen ACC is powered on and if the environment image messages sent by the environment image controller are received for 1s continuously, displaying according to the environment image video display logic; if the right blind area message sent by the right blind area controller is received for 1s continuously, displaying according to right blind area video display logic; if the right blind area message and the ring scene image message are not received, displaying according to the common video display logic; and if the reversing image camera is detected, performing reversing image video display and entering a reversing image video display interface. According to the system and the method, two driving auxiliary videos are displayed simultaneously, including, the environment image + the reversing image, the right dead zone + the reversing image, and the common video + the reversing image, and thus the driving safety and convenience are improved.

Description

technical field [0001] The invention relates to a driving assistance video display system, more specifically to a driving assistance video display system and method of a vehicle-mounted information display screen, and belongs to the field of electronic and electrical technologies. Background technique [0002] The driving assistance system includes reversing image, surround view image, right blind spot, etc., which play a role in assisting driving during driving, enabling the driver to easily and intuitively see the environment outside the car, improving driving safety and convenience. At present, the driving assistance video is mostly integrated on the vehicle information display screen. Due to the differences in the display logic of different functions, the current display screen only supports one driving assistance video signal access display, so it cannot meet the driver's needs.

Problems solved by technology

At present, the driving assistance video is mostly integrated on the vehicle information display screen. Due to the differences in the display logic of different functions, the current display screen only supports one kind of driving assistance video signal access display, so it cannot meet the needs of drivers.

[0003] Different display functions have different logics for entering the video display screen during driving. Therefore, it is necessary to match the display screen. In order to enable a variety of driving assistance videos to be connected and displayed, it is mainly realized through the following two methods: 1. Through parts Separate part numbers for display screens that display different driving assistance video functions; however, it increases the difficulty in the management and control of OEMs and spare parts, and lacks modular design

2. The user manually enters the interface and clicks to select, but this kind of off-line debugging personnel needs to enter the display screen interface to select and operate to debug the function, which increases the complexity of debugging; and the driver is prone to misunderstand during use, thinking that There are multiple functions, if the click is wrong, the matching function will not work

However, the display screen HUD in this patent only receives a video signal output after processing for display, which cannot meet the needs of the driver.
