Electronic control module communication method and device and vehicle with same

Abstract

The invention discloses an electronic control module communication method and a device and a vehicle with the same. The electronic control module communication method comprises the steps that a wakeup request of at least one function module corresponding to at least one electronic control module of a plurality of electronic control modules is received; network requirement managing message is sent to activate a CAN bus, so that the multiple electronic control modules can acquire corresponding network message from the CAN bus; and after the preset time for sending the network requirement managing message, the electronic control module which operates according to the network message among the multiple electronic control modules releases the CAN bus, so that unoperated electronic control modules enter a dormant state. According to the electronic control module communication method, the CAN bus can be released in time, so that useless power consumption of other electronic control modules can be avoided, useless power consumption of the vehicle is reduced, and energy resources are saved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an electronic control module communication method and device and a vehicle having the same. Background technique [0002] Related technologies, when the nodes in the ECU (Electronic Control Unit, automobile electronic control module) are in the network management mode, if a certain ECU is activated due to local functions, the entire automobile bus network will be awakened, so that All ECUs will be in the wake-up state, even if the awakened local function has nothing to do with other ECUs on the bus, since the ECU running the local function has not released the bus, all ECUs on the bus are still in the active hold state. [0003] To sum up, the ECU whose local function is activated, because the bus network is not released in time, causes all ECUs to be in the active state until the local function of the ECU ends, that is, after the ECU sleeps, other ECUs can sleep. Thereby se...

Problems solved by technology

[0003] To sum up, the ECU whose local function is activated, because the bus network is not released in time, causes all ECUs to be in the active state until the local function of the ECU ends, that is, after the ECU sleeps, other ECUs can sleep. Thereby seriously increasing the power consumption of the whole vehicle, especially increasing the useless power consumption of the whole vehicle, wasting energy
