Abstract

The invention discloses a P-gear control device and method for a gearbox OBD fault simulation test. The device comprises a tool body which can be detachably connected with a gearbox controller, and the tool body is slidingly provided with a deflector rod part for switching the gears of the gearbox controller and a limiting part for limiting the deflector rod part. The locking memory of the gearboxcontroller for the P-gear physical position is met, a vehicle can successfully release P-gear locking and smoothly pass P-gear position signal check after the equipment is installed, and a test can be normally carried out.

Description

technical field [0001] The invention belongs to the technical field of gearbox testing in automobile vehicle tests, and specifically discloses a P gear control device and method for OBD failure simulation tests of gearboxes. Background technique [0002] According to the requirements of GB18352.6-2016 "Light Vehicle Pollutant Emission Limits and Measurement Methods" (Phase 6), all automobile manufacturers need to complete a new OBD system monitoring test, which is the mass production vehicle evaluation test. In the mass production vehicle evaluation monitoring requirements verification J2 test, it is necessary to conduct OBD fault code simulation tests for all controllers involved in the OBD system. Among them are the fault simulation test requirements in the transmission controller. [0003] Referring to the same type of test situation, in the OBD-demo demonstration test, in order to complete the typical fault simulation in the engine controller, the engine controller is r...
