Embodiment

[0027] Example: First put all the originals in accordance with the figure 1 The state shown is connected, and the detection can be carried out after the connection is completed. First, the computer software is used to send 1000mA current to the 1st to 10th solenoid valves in the test solenoid valve group 16, and observe whether the solenoid valve corresponding to the solenoid valve group 16 is 1000mA. Work and whether the output current of the regulated DC power supply is up to standard; then send 0, 500, and 1000 frequency current signals to the lightPWM output 8 and RPMPWM output 9 respectively through computer software, and observe whether the display of the oscilloscope 18 is correct; The 1st to 6th relays and the 7th and 8th spare relays in the relay send signals 0 and 1, and observe whether the corresponding indicator lights of the relay measurement indicator group 13 are on or off; respectively adjust the 8th gear switch A4 and the 8th gear switch B5, 8 The gear switch ...

Abstract

The invention discloses a control system detection device and a detection method thereof. The device includes a detected controller, a detected relay and a detected gear selection device; the detected controller is connected with a 8-gear switch A, a 8-gear switch B, a 8-gear switch C, rotation speed input, light PWM output, a relay measurement indicator lamp group, a test battery valve group and a can interface through a 92-core plug, wherein the 8-gear switch A, the 8-gear switch B, the 8-gear switch C, the rotation speed input, the light PWM output, the relay measurement indicator lamp group, the test battery valve group and the can interface are connected in parallel; the detected relay is connected with RPMPWM output and a direct-current power source; the detected relay is connected with the detected controller; and the detected gear selection device is connected with the detected controller. The control system detection device and the detection method thereof of the invention have the advantages of simple and reliable structure, intuitive detection process and the like, and can effectively improve inspection efficiency and reduce detection cost.

Description

technical field [0001] The invention relates to the technical field of circuit detection, in particular to a control system detection device and a detection method thereof. Background technique [0002] With the continuous improvement of automotive electronic technology, more and more electronic controllers are used in vehicles, and the functions of automotive control systems are becoming more and more complex. The electronic control system on the car needs to be tested before leaving the factory. The main test is whether the circuit is connected to ensure that the control system can work normally and eliminate defective or waste products. At present, the common method of detection of electronic control system is to connect the control system and vehicle equipment for detection. The advantage of this method is that it can be combined with the use of equipment, and can fully reflect the functions and faults of the control system. The disadvantage is that the cost is high and ...
