Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] refer to figure 1 , figure 1 It is a structural block diagram of the first embodiment of the power drive fault testing system of the present invention. The power drive fault test system includes: a host computer 10, a fault test device 20, a keyless entry and start PEPS controller 30, and the PEPS controller includes a plurality of power output ports 40;

[0047] In this embodiment, the host computer 10 sends a test command to the fault testing device 20, and the host computer 10 is used to start the power drive fault test.

[0048] In this embodiment, the fault testing device 20 receives the test instruction sent by the host computer 10, and after receiving the test instruction, the fault testing device 20 sends to each of the keyless entry and startup PEPS controller 30 The power output port 40 sends prese...

Abstract

The invention belongs to the technical field of automobile power supply test, and discloses a power-driven fault test system and method. The system comprises a keyless entering and starting PEPS controller, fault test equipment and an upper computer, wherein the PEPS controller comprises a plurality of power output ports, the upper computer is used for sending a test instruction to the fault testequipment, the fault test equipment is used for receiving the test instruction and inputting preset fault information to each power output end of the PEPS controller, each power output port is used for receiving preset fault information, outputting a fault voltage value according to the preset fault information and sending the fault voltage value to fault detection equipment, and the fault test equipment is further used for receiving the fault voltage value, comparing the fault voltage value with a preset voltage threshold and reading a diagnosis fault code of each power output port when the fault voltage value conforms to the preset voltage threshold. By the system, the power-driven test accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of automobile power supply testing, in particular to a power supply drive fault testing system and method. Background technique [0002] The keyless entry and start system, referred to as PEPS (Passive Entry Passive start), controls and distributes the power supply status of the vehicle. PEPS controls whether the relay can be normally engaged and the electrical equipment through the 12V effective output of the ACC, IG1 and IG2 circuits. Can the power supply be normal? When the ACC, IG1, and IG2 output terminals are activated and cannot output 12V voltage normally, PEPS will record a fault code (DTC). Through DTC, we can intuitively find the problem and perform maintenance. It is particularly important whether PEPS can accurately record the abnormal DTC of the power supply drive. [0003] In the prior art, the test for power drive is to turn ON the whole vehicle on the real vehicle, short-circuit the output ...
