Embodiment 1

[0016] like figure 1 As shown, in the backlight processing method of the automobile combination instrument, the body controller is respectively connected with the backlight switch, the backlight regulator, and the relay switch of the automobile position lamp, and the body controller is connected with the backlight through a conversion circuit.

[0017] like figure 2 As shown, the conversion circuit includes a first resistor R1, a second resistor R2, a capacitor C1, and an NPN transistor Q1. The series circuit formed by the first resistor R1 and the second resistor R2 connected in series is connected in parallel with the capacitor C1 to form a parallel circuit. One end of the parallel circuit is connected to the vehicle body controller, the other end is grounded, the junction of the first resistor R1 and the second resistor R2 is connected to the base of the NPN transistor Q1, and the collector of the NPN transistor Q1 passes through the backlight of the combination instrument...

Abstract

The invention provides a backlight processing method of an automobile combination instrument, which aims to solve the problem of backlight mutation of a combination instrument, avoid inadaptation of vision of a driver due to backlight brightness mutation and improve the driving comfortability of a whole automobile. The backlight processing method of the automobile combination instrument comprises the following steps that an automobile body controller is respectively connected with a backlight lamp, a backlight lamp switch and a backlight lamp adjuster of the combination instrument, after a signal of the backlight lamp switch is received by the automobile body controller, a backlight value signal of the backlight lamp adjuster is read first, then the brightness of the backlight lamp is adjusted in accordance with the backlight value signal, and the brightness of the backlight lamp is controlled by the automobile body controller to gradually increase until the brightness of the backlight lamp meets the requirement of the backlight value signal. According to the backlight processing method, after the backlight of the combination instrument is turned on, the backlight brightness of the combination instrument is gradually changed, the problem of the backlight mutation of the combination instrument is solved, the inadaptation of the vision of the driver due to the backlight brightness mutation is avoided, and the driving comfortability and safety of the whole automobile are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to a backlight processing method of an automobile combination meter. Background technique [0002] With the development of automobile technology, people have higher and higher requirements for the safety of the whole vehicle, and at the same time have higher requirements for the driving comfort of the whole vehicle; and the backlight of the instrument cluster is the most intuitive part for the driver. It has also received increasing attention. At present, the brightness of the combination instrument of many models will change suddenly when the backlight is turned on, which will cause temporary discomfort to the driver's vision, affect driving comfort, and even affect driving safety. Contents of the invention [0003] The purpose of the present invention is to propose a backlight processing method for an automobile combination meter to solve the problem...
