Testing device of vehicle control unit

Abstract

The invention provides a testing device of a vehicle control unit. The testing device comprises a first terminal, a second terminal, a third terminal, a fourth terminal, a fifth terminal, a sixth terminal, a seventh terminal, an eighth terminal, a ninth terminal, a tenth terminal, a power source module, a core control module, a PWM signal generation module, an analogue signal generation module, adigital signal generation module, a PWM signal detection module, an analogue signal detection module, a digital signal detection module and a CAN communication module. The testing device can replacea practical automobile part in the testing work of the vehicle control unit, complex building work of a testing environment is omitted, the rapid and convenient testing environment is provided for thetesting work, the testing work is greatly simplified, the working cost is obviously reduced, the system can further be used in a production line of the vehicle control unit to achieve rapid detectionof a hardware failure state.

Description

technical field [0001] The invention relates to the technical field of electric vehicle controllers, in particular to a testing device for a vehicle controller. Background technique [0002] With the country's vigorous promotion of new energy electric vehicles and electric motorcycles, the field of new energy vehicle vehicle controllers (VCU) is showing a rapid development trend. The vehicle controller (VCU) is the core control component of the entire new energy vehicle. It collects accelerator pedal signals, brake pedal signals and other component signals, and manages, schedules, analyzes and calculates network information. After making corresponding judgments, Control the action of each component controller in the lower layer. The vehicle controller (VCU) implements energy management, such as vehicle drive control, energy optimization control, brake feedback control, and network management. [0003] The vehicle controller (VCU) involves many automotive components and nee...

AI Technical Summary

Problems solved by technology

[0003] The vehicle controller (VCU) involves many automotive components and needs to implement complex control logic. In the prior art, the testing work of the vehicle controller must rely on the vehicle system, which imposes a huge burden on the development process of the vehicle controller. Test work brings a lot of inconvenience
