Problems solved by technology

At present, in order to facilitate the inspection of network communication faults, some vehicles lead the CAN, LIN, and K lines of the vehicle to the OBD port for detection. This can solve the quick inspection of network communication faults, but increases the length and cost of the wiring harness.
The current detection methods and methods will reduce the service life of the wiring harness, which is time-consuming and laborious, and the connection is also unstable, which will also lead to high cost of the vehicle wiring harness

Embodiment Construction

[0022] The scheme of the patent of the present invention will be described in detail below in conjunction with specific examples.

[0023] like figure 1 , a fault detection device for automotive wiring harnesses, consisting of male terminals and connectors, female terminals and connectors, wiring boards, signal conversion connectors, and wire harnesses. The docking part of the wiring harness, the female terminal and the connector constitute the docking part connecting different controllers of the vehicle, and the wiring board integrates the one-to-one corresponding pins of the wiring harness end and the controller end, which are respectively arranged in different areas of the wiring board ( Areas A, B, C, D, etc.), the corresponding pins of the wiring harness end and the corresponding pins of the controller are in one-to-one correspondence on the wiring board, and the two are not connected on the wiring board. Connect the pins of the controller and the wire harness, and use c...

Abstract

The invention relates to an automobile fault detection device and method, the automobile fault detection device comprises a male end terminal and a connector assembly, a female end terminal and a connector assembly, a wiring board, a signal conversion joint and a wire harness, the male end terminal and the connector assembly form a butt joint part for connecting the whole automobile wire harness, and the female end terminal and the connector assembly form a butt joint part for connecting different controllers of the whole automobile. On the premise that the wire harness is not damaged, connection and disconnection of the wire harness can be simulated through plugging and unplugging of the signal conversion connector, flexible conversion and expansion can be carried out according to different connectors of a controller, the cost is low, the development period is short, and operability is high.

Description

technical field [0001] The invention relates to a vehicle network troubleshooting wiring harness or a PVE mass-produced vehicle evaluation test, in particular to a fault detection device and method for an automotive wiring harness. Background technique [0002] At present, when ECU-related functions fail in vehicles, vehicle network troubleshooting or PVE mass-produced vehicle evaluation tests, it is generally achieved by inserting corresponding pins, breaking wires and inserting pins, and inserting and unplugging corresponding insurance. At present, in order to facilitate the inspection of network communication faults, some vehicles lead the CAN, LIN, and K lines of the vehicle to the OBD port for detection. This can solve the quick inspection of network communication faults, but increases the length and cost of the wiring harness. The current detection means and methods will reduce the service life of the wiring harness, which is time-consuming and laborious, and the conne...
