Embodiment

[0022] Example: such as figure 1 As shown, there are MODE key 1, left key 2 and right key 3 arranged on the right side of the steering wheel. There are two ways to connect these three keys to the instrument panel (IP), one is to connect through the multimedia interactive system (MMI) (for high and high-end models), and the other is to connect through the radio (for low-end models).

[0023] When connecting via MMI, press and hold the MODE button for more than 2 seconds and release it, MMI judges the duration of the button, and outputs a CAN message to notify the meter to enter the "instrument working mode";

[0024] Enter the "instrument working mode" to generate a prompt sound, and then the instrument HMI displays the content of "trip computer", press the left and right keys to switch the trip computer screen, short press the MODE button to enter the "main menu", long press the MODE button to "reset".

[0025] In the instrument menu interface, short press the left button and...

Abstract

The invention discloses a reusing control method for keys on a steering wheel. The method comprises the following steps that A, a controller detects key conditions, and enters step B when the MODE key is pressed and the time length T between the pressing and the releasing of the MODE key exceeds 2 seconds; B, a system enters an instrument working mode, and when all of the MODE key, the left key and the right key are not operated for 10 seconds, quits the instrument working mode, and returns to step A; in the instrument working mode, the controller transmits a corresponding signal to an instrument according to the pressing time length of the MODE key, the left or the right key. According to the scheme, the keys on the steering wheel can be reused, and the same keys can be used for making judgments in double operating modes, so that the number of the keys on the steering wheel is reduced, the cost is lowered, control experiences are improved, and safety is improved; the scheme is applied to all automobile steering wheels.

Description

technical field [0001] The invention relates to the field of automobile instrument control, in particular to a steering wheel button multiplexing control method which can save buttons. Background technique [0002] With the development of control technology and the increase of vehicle-mounted auxiliary electronic systems, more and more functions need to be operated and controlled by the buttons on the steering wheel in order to operate these vehicle-mounted systems more conveniently during driving. Existing technologies all solve the problem of insufficient number of buttons by adding buttons or transferring the buttons that cannot be placed on the steering wheel to the instrument panel or combination switch of the car. Adding switches in this way will not only increase the cost of the product, but also increase the number of buttons will make the man-machine operation experience not good, and it is difficult to find a more comfortable and convenient position to arrange. Th...
