Abstract

The invention discloses a state control method of a vehicle controller, a system and a vehicle thereof. The method comprises the following steps that after being activated in a CAN network, a main node sends a communication request message to the CAN network so as to maintain an activation state of the CAN network; in the CAN network, a slave node is awakened according to the communication request message and then sends response information to the main node, and determines whether the slave node itself has a network communication demand; and if the slave node does not have the network communication demand, the slave node enters into a dormant state, otherwise, the slave node sends the communication request message to the CAN network. By using the state control method of the vehicle controller, the corresponding controller can be activated when a vehicle function is used, and the controller can enter into the dormant state when not being used so that energy is saved and the vehicle function can be ensured to be safe and effective.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a state control method and system of a vehicle controller and a vehicle. Background technique [0002] As the functions of automobiles become more and more abundant, the traditional point-to-point communication method leads to complex wiring harnesses in the car, difficult wiring and increased interference. Therefore, the control area network CAN (Controller Area Network) has become the mainstream of the development of the automotive internal network by virtue of its high real-time and reliability. [0003] Common controllers that use CAN bus for communication mainly include engine control unit, body control unit, ABS control unit, gearbox control unit, reversing radar control unit, keyless start system control unit, instrument and door controller. New energy vehicles also include battery management systems, motor control units, and charger control units. Therefore, when th...
