Abstract

The invention provides a control method, device and system of an electric vehicle controller, and a gateway controller. The method comprises the following steps: a gateway controller connected with atleast two control area networks(CAN)on an electric vehicle collects dormancy condition data and wake-up condition data of the at least two CANs, performs the dormancy processing on a first network when the first CAN satisfies a preset dormancy condition, controls each controller in the network to enter a dormancy state, and stops forwarding message information of each controller in the network; and the gateway controller performs the wake-up processing on a second network when the second CAN satisfies the preset wake-up condition, forwards the message information of each controller in the network, and forwards the message information to each controller in the network, thereby controlling all controllers in the CAN to enter the dormancy state when all controllers in the CAN are out of work. The energy consumption of the electric vehicle is reduced, the endurance mileage and the energy service efficiency of the electric vehicle are improved, and the use experience of the electric vehicle is improved.

Description

technical field

[0001] The invention relates to the technical field of vehicles, in particular to a control method, device, system and gateway controller of an electric vehicle controller. Background technique

[0002] In the current electric vehicles, not all controllers need to work normally in various working conditions such as power off, fast charging, and slow charging. In each working condition, all the controllers keep working, which leads to high energy consumption of electric vehicles, reduces the cruising range of electric vehicles, and reduces the energy efficiency of electric vehicles, especially for batteries with limited battery capacity. Vehicles affect the experience of using electric vehicles. Contents of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0004] Therefore, the first object of the present invention is to provide a control method for an electric vehicl...
