Importance of Automotive Parts Testing?

The testing of automotive components is critical in ensuring the safety, functionality and reliability of automobiles. Common LIN/CAN communications are used for vehicle components such as window rollers, wipers, grilles, sunroof motors, as well as for testing equipment such as combination switches, seats and ambient lighting. Customers need to verify the functionality and reliability of these components in automated test systems, so powerful LIN/CAN bus test simulation tools are key.

Solution Features and Application Scenarios

Supports event-driven signal configuration and sequence control, providing error determination and triggering functions to fully simulate and test the quality, function and control of vehicle components.

Function test of steering wheel switch

- Realization of key detection and function tests for backlight function, heating function, HOD function, etc.
• SDF programmable macros can be scripted to assign signals and run.

Control testing of various types of motors

• Controls automotive sunroof motors, air conditioning motors, detectsAutomotive switches, shifter quality, etc.
• Convenient push-button control of the motor for different operations
• Monitoring of motor operation status via PC or PLC.

RGB Ambient Lighting Function Test

- 3C Diagnostic Message for Automatic Address Assignments
• Realization of different RGB light colors and brightness tests

Application Scenario 1: Steering Wheel Switch Function Test

The function test of steering wheel switch mainly includes: key detection and backlight function, heating function, HOD function and other tests, which can be completed by using BabyLIN series products. For example, using Baby-LIN-RM-III to test car switches, the following functions can be realized:

When a key is pressed on the steering wheel, the corresponding LIN signal is converted into a digital output event on the BabyLIN RM-III, which is outputted to the PLC for logical judgment to detect the key function of the steering wheel.

The backlighting and heating functions of the steering wheel switch can be assigned to the signal and run by writing SDF program macro scripts, so as to realize automatic activation of the steering wheel when it is powered on or manual activation.

Application Scenario 2: Control testing of various types of motors

Control testing of motors in automotive subcomponents (e.g. sunroof motors, air-conditioning motors) can be realized with the BabyLIN series. By using different BabyLIN products, individualized testing of motor control functions can be accomplished:

Use Baby-LIN-RC-II to control the sunroof motor. RC-II can control the motor with six buttons to realize different operations, and it can realize the functions of initializing, opening, and closing the glass motor and sunshade motor.

Using Baby-LIN-MB-II to control various motors of automobile air-conditioning system, it sends different serial commands through PC or PLC to control the operation of one or more motors, and monitors the operation status of the motors at the same time.

Application Scenario 3: Functionality Testing of RGB Ambient Lighting

Product testing of RGB scent lamps often requires the connection of multiple identical RGB scent lamps for simultaneous testing. The following is a functional test program for RGB scenters with diagnostic auto address assignment using BabyLIN products in a 4-wire system:

For applications where multiple identical nodes are being tested on the same LIN network, it is necessary to implement an automatic address assignment function. For the implementation of automatic address allocation, 3C diagnostic message can be used for request.

Adopting the function of SDF V3 version, the command of automatic address allocation is unitized and modularized by means of protocol. After assigning the Frame ID, it is possible to realize different RGB lighting colors and brightness tests.
