Test simulator of automotive electronic controller

Abstract

The invention discloses a test simulator of an automotive electronic controller and aims to solve the problem of resource waste in function and performance when a current general high-performance hardware-in-loop system is applied to the automotive electronic controller. The test simulator of the automotive electronic controller is composed of a server and a CompactRIO real-time control system, wherein the server is connected with the CompactRIO real-time control system through an Ethernet line; the CompactRIO real-time control system is composed of a CompactRIO integration system and a CompactRIO I / O (Input / Output) module; the CompactRIO integration system integrates a real-time processor and a reconfigurable FPGA (Field Programmable Gate Array) cabinet and is connected with the CompactRIO I / O module through a serial interface; the tested electronic controller is connected with the CompactRIO I / O module through a VCU (Vehicle Control Unit) hardware interface; a real-time controller transfers data to the server through TCP / IP (Transmission Control Protocol / Internet Protocol), and the server transfers the data to the real-time controller through a network sharing variable; the real-time controller communicates with the FPGA cabinet through an FPGA interface; communication between the FPGA cabinet and the tested automotive electronic controller is completed through data transmission based on a CAN (Controller Area Network) bus communication protocol and input / output of an analog-to-digital signal.

Description

technical field

[0001] The invention relates to an automobile electronic control device, in particular to a vehicle electronic controller test simulator. Background technique

[0002] With the rapid development of the field of automotive electronic control, the electronic control system is becoming larger and larger. Many electronic controllers are installed on a mid-to-high-end car. In order to ensure the safety of the car, the software and hardware testing of the electronic controller has become the core content of the development of the automotive electronic control system. one.

[0003] At present, the international mainstream electronic controller simulation test is called hardware-in-the-loop, that is, through special high-performance software and hardware, various working conditions of the electronic controller are simulated, so as to effectively test the function and operation process of the electronic controller in real time in the reliability. This kind of hardwa...
