Abstract

The embodiment of the invention discloses a detection method and device for a vehicle control unit, which relate to a vehicle detection technology, and can solve the problem that the detection efficiency is low in the detection process of an existing vehicle control unit. The method provided by the embodiment of the invention mainly comprises the steps that a vehicle operation record is acquired, the vehicle operation record is operation data acquired in the operation process of a tested VCU in a vehicle, and the vehicle operation record comprises data in the unexpected shutdown fault process of the tested VCU; according to the vehicle operation record, a simulation test is conducted on the tested VCU, and test data in the simulation test process is obtained, wherein the test data includes VCU signal data obtained during the simulation test of the tested VCU; target data in the vehicle operation record is determined according to the test data and a deviation value between the VCU signal data in the vehicle operation record; and the fault cause of the tested VCU is analyzed according to the target data. The embodiment of the invention is mainly suitable for the detection process of the vehicle control unit.

Description

technical field [0001] Embodiments of the present disclosure relate to vehicle detection technology, in particular to a detection method and device for a vehicle controller. Background technique [0002] With people's consideration of environmental protection and economy, traditional gasoline and diesel vehicles have been difficult to meet people's more economical and more environmentally friendly needs. Therefore, new energy vehicles have gradually become the main development direction of the automotive field. Among them, the new energy vehicle is provided with a VCU, that is, a vehicle controller, through which various functions in the vehicle can be controlled. For the use of new energy vehicles, whether there is a fault in the VCU and whether it can operate normally will directly affect the normal driving of the vehicle. Therefore, it is of great significance for the safe driving of the vehicle to carry out fault detection on the VCU. [0003] Usually, during the opera...
