Problems solved by technology

[0004] However, the existing communication scheme of the front windshield head-up display is to increase the definition of CAN bus information, add the defined information to the CAN bus and send it to the head-up display separately, which will increase the load rate of the CAN bus , not only increases the communication burden of the CAN bus, but also increases the probability of delay, slows down the response time of displayed information, delays or false alarms for driving safety warnings that are highly concerned, resulting in the driver's inability to respond immediately. Unable to respond to changes in driving conditions in a timely manner

Embodiment Construction

[0044] figure 1 It is a flow chart of the steps of a method embodiment of the present invention, such as figure 1 As shown, an embodiment of the present invention provides a method for information interaction of a head-up display, including:

[0045] Step 101, establishing a direct information channel between the instrument cluster and the head-up display through an independent asynchronous serial communication protocol; the independent asynchronous serial communication protocol includes communication protocol structure, communication timing definition and information transmission format;

[0046] Step 102, the combination instrument obtains the current vehicle driving information, and directly sends it to the head-up display through the independent asynchronous serial communication protocol;

[0047] Step 103, the head-up display displays the current vehicle driving information.

[0048] As can be seen from the above, in the embodiment of the present invention, an independe...

Abstract

The invention provides a method and system for HUD (Head Up Display) information interaction, the method comprises: setting up a direct information channel between a combination meter and an HUD through an independent asynchronous serial port communication protocol; the independent asynchronous serial port communication protocol comprises a communication protocol structure, a communication timing sequence definition and an information transmission format; the combination meter obtains current vehicle running information, and directly sends the information to the HUD through the independent asynchronous serial port communication protocol; the HUD displays the current vehicle running information. The method and system can shorten the response time of display information, reduce the time delay probability, and enable a driver to cope with the change of a running condition.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method and system for information interaction of a head-up display. Background technique [0002] HUD is the abbreviation of Head Up Display, and the Chinese translation is head-up display or head-up display. [0003] HUD was originally a technology applied to fighter jets. Head-up means that the pilot can see the important information he needs without looking down, reducing the frequency of the pilot needing to look down at the instruments, avoiding interruption of attention and loss of state awareness. Because of the convenience of HUD and its ability to improve flight safety, civil aviation aircraft have also followed up with the installation, and now it is gradually becoming popular in the automotive industry. HUD projects the important information of the vehicle, such as speed (Speed), steering (Direction), navigation (TbT Navi), mid-range cruise radar (ACC), lane departure wa...
