Abstract

The invention is suitable for the technical field of communication, provides a method and device for obtaining a vehicle signal value, electronic equipment and an electronic control unit, and can improve the efficiency of obtaining the vehicle signal value. The method comprises the steps of sending a request message to a target ECU, wherein the request message comprises a request message identifier and a preset specified code, and the preset specified code is used for specifying a to-be-monitored signal; receiving a response message, wherein the response message is generated according to the message format and the signal value corresponding to the request message identifier after the target ECU obtains the signal value of the to-be-monitored signal specified by the preset specified code; and analyzing the response message to obtain a signal value of the to-be-monitored signal.

Description

technical field [0001] The present application belongs to the technical field of electric communication, and in particular relates to a method for acquiring vehicle signal values, electronic equipment and an electronic control unit. Background technique [0002] At present, the signal value refers to the data generated by ECU (Electronic Control Unit, Electronic Control Unit) communicating with sensors and actuators, which will change with time and working conditions. When the ECU receives a message, it will count how many signal values ​​are included in the message, and then obtain the latest data of these signal values ​​in turn, and then send a response message through the bus, so that other devices can get the latest data through the message. [0003] At present, a single message of many ECUs contains the values ​​of multiple signals. Before sending a message, it is necessary to obtain the latest values ​​of multiple signals, and then generate and send a response message...
