Abstract

The embodiment of the invention provides a control method and device of a vehicle controller and an automobile. The control method of the vehicle controller comprises the following steps: after being awakened according to a local awakening event, a first controller sends a wake-up message to at least one second controller in the network; after a wake-up response message fed back by at least one second controller according to the wake-up message is received and the network is activated, a message is sent to the application through the network; and when the application determines that the first controller needs to sleep according to the message, the first controller and at least one second controller are powered off. According to the scheme, the controller can be powered on in time under the condition that the controller is awakened and can also be powered off in time when the controller is in the dormancy state, and the situation that the whole vehicle is insufficient in power is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and device of a vehicle controller and an automobile. Background technique [0002] At present, pure electric vehicles tend to be intelligent, and more and more functional requirements controllers are awakened by CAN bus messages instead of KL15 power; Klemme refers to the pins of ECU. The most commonly used are KL15, KL30, KL31, KL61; KL15 represents the engine ignition signal. It also indicates the signal to turn the car key to start the car. Most ECUs can only work when the car is started. Some will be divided into KL15R, R means Radio, that is, the key is turned to the place where the radio works, but the car has not started yet, such as the instrument panel, doors and windows are connected to this signal. This signal is powered by Zentrale Elektrik (the main electric box in the car), and is connected to the KL15 pin of each ECU through a fuse. KL30 i...
