Abstract

The invention provides a steering wheel key adaption method and device, and the method comprises the steps: configuring a pull-up resistor and a gating circuit; determining the resistance value of an automobile steering wheel control key; calculating and determining the pull-up resistor; and determining the output level of each output end of the gating circuit. The method and device achieve the automatic determining of the pull-up resistance of a control function of the steering wheel of a modified machine, and improves the modification efficiency and user experience.

Description

technical field [0001] The present invention relates to the technical field of vehicle electronics, in particular to a steering wheel button adaptation method and device. Background technique [0002] At present, automobiles are widely popularized as a means of transportation. In order to facilitate the driver to operate the in-vehicle system during driving, some commonly used buttons are configured on the steering wheel of a car with a higher configuration, which can be used to control the in-vehicle system, such as play, pause, up and down song selection, volume adjustment, etc. These buttons Call it the steering wheel buttons. The use of steering wheel buttons greatly improves the driving safety performance. The steering wheel control function of the pre-equipped vehicle system of the car is matched with the steering wheel buttons of the car when it leaves the factory, so the general functions are normal. However, when the user modifies the vehicle system, the steering ...
