Control method and system for gear lamp in charging mode

Abstract

The invention provides a control method and system for a gear lamp in a charging mode. The control method comprises the steps that a wake-up signal of a VCU is responded, and the VCU is awakened; a whole vehicle signal is received and a target signal is identified from the whole vehicle signal; whether the whole vehicle enters a normal charging mode or not is judged according to the recognized target signal; and if so, an energy-saving signal is sent to a gear lamp so as to control the gear lamp to enter a preset energy-saving mode. After the SCU responds to the awakening signal of the VCU and is awakened, the SCU can receive the whole vehicle signal, recognize the target signal from the whole vehicle signal and judge whether the whole vehicle enters the normal charging mode or not according to the recognized target signal, and if the whole vehicle enters the normal charging mode, the SCU sends an energy-saving signal to the gear lamp. And thus the gear lamp is controlled to enter the energy-saving mode, so that the gear lamp is prevented from entering the working normally-on state in the whole vehicle charging mode, the energy consumption can be effectively reduced, and the service life of the gear lamp is prolonged.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a control method and system for a gear position lamp in a charging mode. Background technique [0002] At present, because the pure electric vehicle is in the charging mode, the whole vehicle will be in a high-voltage state, the control unit VCU of the whole vehicle will be awakened by the high voltage, and the SCU will also wake up accordingly. The SCU will control the gear light to work and keep it on, so it will consume Part of the energy of the vehicle, while reducing the service life of the gear lights. Contents of the invention [0003] The purpose of the present invention is to propose a control method and system for the gear light in the charging mode, so as to solve the problem of the prior art when the vehicle is in the charging mode, the VCU is awakened, and the SCU is also woken up, so that the SCU controls the gear light to work and Keeping the lights on will consume pa...
