CANBUS network-based whole vehicle quiescent current control method

Abstract

The invention discloses a CANBUS network-based whole vehicle quiescent current control method, comprising the following steps: a vehicle body control module judges the current mode of a vehicle and enters a corresponding mode according to the judgment; the vehicle body control module monitors an input signal, the variation of input quantity and CAN data; the vehicle body control module judges whether the input signal is detected, if the input signal is not detected, the vehicle body control module sends a sleep-entering signal to a combination meter module to lead the combination meter moduleto enter a sleep state; the vehicle body control module judges whether the variation of input quantity and the CAN data are detected, if the variation of input quantity and the CAN data are not detected, the vehicle body control module enters an energy-saving state; and the vehicle body control module sends a signal to an power-operated sliding door module in the condition of vehicle locking and controls the power-operated sliding door module to enter a low power consumption state. The method can effectively control the quiescent current consumption of the power-operated sliding door module, and strengthen the control on the quiescent current during the quiescent current of the vehicle, thus effectively reducing the quiescent current consumption of the whole vehicle.

Description

technical field [0001] The invention relates to the field of vehicle electronic control, in particular to a method for controlling the static current consumption of the whole vehicle and the static current consumption of an electric sliding door module and a system for controlling the static current of the whole vehicle during the long-distance transportation of the vehicle. Background technique [0002] In recent years, with the increasingly stringent emission standards, safety standards and users' pursuit of safety, comfort and luxury of vehicles, there are more and more ECU control units on vehicles. Controller Area Network (CAN) bus technology uses CAN bus technology to connect the entire vehicle control system for unified management, making wiring harness wiring in the car convenient and reliable, and at the same time realizing data sharing and mutual cooperation, in terms of stability, immediacy and The cost performance and other aspects have shown strong advantages in...

Problems solved by technology

However, the network control system provided by this invention still does not solve the static current control of the vehicle well, such as the control of the static current of the vehicle power sliding door module (PSD), and the network control system does not provide the vehicle in the long-distance transportation mode. The quiescent current control method of
