Example Embodiment

[0012] The present invention will be described in detail below with reference to the accompanying drawings.

[0013] The invention provides a method for switching the state of a constant power node in a vehicle electronic system. The method includes: in the activated state, the constant power node consumes power, works, and sends its own state to other constant power nodes, and when the pre-sleep condition is met, Enter the pre-sleep state; in the pre-sleep state, the normal power node consumes power, works, sends its own status to other normal power nodes, and continuously monitors the status of other normal power nodes: when judging that other normal power nodes are maintained in the pre-sleep state It enters the waiting dormancy state under the condition of the power supply, and enters the active state when receiving the wake-up signal; in the waiting dormancy state, the normal power node consumes power, does not work, and continuously monitors the status of other normal pow...

Abstract

The invention discloses a vehicle electronic system constant-electric node state switching method, a constant-electric node network and a vehicle. The method comprises the steps of: entering a pre-dormancy state under an activation state when a pre-dormancy condition is met; continuously monitoring states of other constant-electric nodes under the pre-dormancy state; entering a dormancy waiting state when all other constant-electric nodes are judged to maintain the pre-dormancy state, and entering the activation state when a wake-up signal is received; entering the pre-dormancy state when any one of other constant-electric nodes is monitored to be in the activation state under the dormancy waiting state, entering the dormancy state when other constant-electric nodes are monitored not to be in the activation state in a first preset time, and entering the activation state when the wake-up signal is received; and under the dormancy state, one constant-electric node continuously monitoring the states of other constant-electric nodes: entering the activation state when any one of other constant-electric nodes is monitored to be in the activation state, and entering the activation state when the wake-up signal is received.

Description

technical field [0001] The invention relates to a vehicle electronic system, in particular to a method for switching the state of a constant power node of the vehicle electronic system, a network of constant power nodes of the vehicle electronic system and a vehicle. Background technique [0002] With the rapid development of automotive electronics, the number of electrical equipment and controller modules in the vehicle continues to increase. After the car turns off the ignition IG power, the body electronic system composed of the constant power nodes of multiple electrical equipment and their respective controller ECUs continues to work with the power provided by the battery. However, the power supplied by the battery is limited, so how to control the wake-up and sleep of the constant power nodes and their networks when parking becomes a very important issue. [0003] In the traditional way, the general vehicle controller waits for a certain period of time after the ignit...
