How can EOL (End-of-Line) testing of automobile steering wheels be "fast" and "stable" at the same time? When the production line is at risk of being shut down due to occasional test failures, how can enterprises realize accurate detection and efficient operation and maintenance through technical means?
This case study takes you to the production line testing site of a leading global automotive parts manufacturer to learn aboutHONGKE Baby-LIN SolutionHow to help top automotive safety system suppliers to move steadily forward on the road to quality and efficiency.
The steering wheel is the core component of vehicle control, and its functional reliability directly affects driving safety. Every steering wheel that comes off the production line must pass strict functional and communication verification - from key response to LIN/CAN communication signals, any slight error may affect the safety performance of the whole vehicle.
Therefore, EOL testing is not only a key step in quality control, but also a guarantee of production stability. The efficiency and accuracy of the test directly determine whether the product can be delivered on time and whether it meets the high standard requirements of the vehicle manufacturers.
In real-world steering wheel EOL testing, engineers are often confronted with tricky repetitive problems:
During the testing process, the steering wheel may have delayed key response, communication error alarms, etc., resulting in test interruptions or even misjudgment, affecting the rhythm of the production line.How to ensure that the test process is not interrupted by occasional communication anomalies?
Traditional test equipment is limited in its ability to track problems and analyze logs. It is often difficult for field personnel to quickly pinpoint the root cause from the huge amount of data.Can you quickly find the key clues in the data when a problem occurs?
If the above problems cannot be solved effectively, it will directly affect the production progress and product consistency.
For automotive parts companies that emphasize long-term stability and line efficiency of their test systems, a set of test equipment that can be used to test the system's performance is essential.Adapts to a wide range of test scenarios while maintaining flexibility in development and stability in operation.The program is of paramount importance.
HONGKE Baby-LIN Series SolutionWith stable hardware performance, flexible system integration capability, and comprehensive technical support system, it can effectively support the test standardization and long-term operation needs of enterprises in the context of multiple production lines and vehicle models.
Hi-Tech solutions are based on Baby-LIN-MB Series LIN / CAN FD ModulesIt is integrated into the steering wheel EOL test stand for precise acquisition and real-time processing of communication signals.
In steering wheel EOL testing, the PLC is usually responsible for controlling the overall test stand. However, since PLCs communicate with external devices via Ethernet or RS232, they do not have the ability to connect directly to the DUT via the CAN / LIN interface.
HOSCO Baby-LIN-MB Series In addition to the CAN / LIN interface, the product also integrates a set of RS232 and Ethernet ports, allowing users to access the Baby-LIN device through other host computers (e.g., PLCs) for easy test control.
In addition.Baby-LIN-MB Series With the rich ASCII command set, the host computer can directly control the pre-programmed test program in the Baby-LIN module through these commands for parameter configuration and result reading without additional coding.
In this case, a PLC with a touch screen provides the operator with an HMI interface, and every time the worker operates the DUT, the Baby-LIN-MB module is driven by the preset ASCII commands to realize CAN / LIN communication control between the worker and the DUT.
HOSCO Baby-LIN Series Equipment Through LIN and CAN node or system master-slave simulation and analysis, we can assist customers to complete the quality, function and control testing of automotive parts, and comprehensively improve the stability and consistency of automotive parts production.
The system supports event-based signaling, sequence control, error determination, and triggered actions, and comes with free LINWorks SoftwareThe test system is designed to provide a user-friendly interactive experience between the functional operation of the test device and the software interface.
1️⃣ Letter Direct, Simplified Development
Hongke Baby-LIN-3-MBIt can directly output signal level data without the need for users to parse the original telegrams, greatly simplifying the development process of the master program.
2️⃣ Built-in Logic for Less Burden
Baby-LIN-MB module supports internal programming and can manage some of the bus tasks independently, which reduces the program development and resource consumption on the main console and allows the team to focus more on the core function design.
3️⃣ Journal Optimization for Efficient Troubleshooting
Supports flexible logging and file configuration to help quickly locate communication abnormalities, significantly improving troubleshooting efficiency and response time in the field.
4️⃣ Stable and Reliable, Continuous Protection
HONGKE's products have demonstrated high stability and reliability in a number of long-term cooperative enterprises, effectively reducing production line interruptions caused by communication errors and ensuring continuous and stable operation of the test.
HOSCO Baby-LIN Series With excellent and stable performance, flexible application adaptability, and a professional technical support team, it has become an indispensable key component in the EOL test system of automotive parts manufacturers.
In the future.HOSCOWe will continue to work with our industry partners to help the automotive industry chain establish a smarter and more reliable testing and verification system, and jointly promote the development of global automotive safety and smart manufacturing.
