Problems solved by technology
[0004] The technical problem to be solved by the present invention is to realize a new type of fault injection system that overcomes the deficiencies of the existing SCU HIL fault injection test. When the function is abnormal or the fault occurs, the car seat can be effectively controlled to prevent the uncontrollable situation from causing harm or disadvantage to the driver or passengers. It can also prevent problems in advance and save repair time and cost for the follow-up

Embodiment Construction
[0017] Referring to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention include the shape, structure, mutual position and connection relationship of each part, the function and working principle of each part, and the manufacturing process of the various components involved. And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.
[0018] Such as figure 1 As shown, the car seat test system uses the board to simulate various fault injection situations (such as simulated open circuit, simulated short circuit, simulated blockage, simulated HALL sensor abnormality, and simulated resistance value abnormality), and sends the injected fault signal to the information processing Module, the information processing module recognizes that ...

The invention discloses an automobile seat test system based on SCU HIL.The SCU HIL is connected with a relay module and transmits a control signal to the relay module, the relay module is connected with an execution module and transmits a driving signal to the execution module to control a seat to move, and the system is provided with a board card module for storing an analog abnormal signal. Theboard card module is connected with the signal processing module and transmits the analog abnormal signal to the signal processing module, and the signal processing module is connected with the SCU HIL and transmits an abnormal code signal to the SCU HIL. According to the invention, the abnormal condition can be simulated in advance, and corresponding processing can be carried out if the functionof the seat is abnormal, the safety and comfort of the seat module are greatly improved by simulating fault injection, the automobile seat can be prevented from going wrong subsequently, and the repair cost is reduced.
Description
technical field [0001] The invention relates to automobile electronic control technology, in particular to the field of automobile seat control. Background technique [0002] At present, the trend of car seats is developing in the direction of safety and comfort. Under the rapid development of today's society, cars have almost become a necessary travel tool for every household. It is one of the most common existences in this society, and the functions of cars are also changing with each passing day. The changes are taking place, the functions are becoming more and more complete and more novel, but with the increase of functions and the improvement of the complexity of functions, there are more situations and faults that do not conform to the functions. The need for a seat, and the failure of a car seat in the event of an accident, does not affect human movement (such as getting in and out of the car). [0003] In order to realize the function of the seat reliably and stably...
