Embodiment Construction

[0013] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] Combine below Figure 1-2 This example will be described.

[0015] Such as figure 1 As shown, terminal 1 is the power input port of the device, which is connected to the target working power of the vehicle controller (VCU), mostly 12V or 24V. Terminal 1 inputs power to the power module, which supplies power to the entire device. The power module is connected to terminal six, and terminal six is ​​connected to the power port of the vehicle controller (VCU) to supply power for the vehicle controller (VCU).

[0016] Terminal five is connected to the CAN communication card of the host computer, and terminal five is connected to the CAN co...

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...
