Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts detection equipment, and in particular, to a detection device and method for an automotive controller. Background Art

[0002] The vehicle control unit (VCU), that is, the powertrain controller, is the core control component of the entire vehicle. After it collects the accelerator pedal signal, brake pedal signal and other component signals and makes corresponding judgments, it controls the actions of the lower-level component controllers to drive the vehicle to run normally. The quality of the VCU directly affects the vehicle performance. In particular, the VCU of a pure electric vehicle is the core component of the pure electric vehicle's entire vehicle control system, and it plays a key role in functions such as the normal driving of the vehicle, fault diagnosis and handling, and vehicle status monitoring. Therefore, the role of the VCU detection equipment is also quite important.

[0003] Currently, the VCU includes a controller body and a circuit board connected to the controller body. There is a special detector for detecting the internal system of the VCU, which mainly detects the controller body. However, during the detection process, the controller body is still connected to the circuit board. The top of this detector is provided with detection probes. These detection probes are numerous and relatively dense. During detection, the through holes at the bottom of the VCU to be measured need to be aligned with them to conduct the detection circuit. Manual alignment reduces the detection efficiency and has poor mechanical performance. Moreover, the existing detector lacks a corresponding protection device for the detection probes, and the detection probes are easily damaged, thus affecting the detection results.
