Abstract

The embodiments of the invention provide an automobile electronic and electrical performance test circuit system. The system comprises a power source module, an output control module and a controllable branching device which are connected in sequence; the power source module comprises a pulse control unit, a programmable power source which is controlled by the pulse control unit, and a plurality of variable resistance networks connected with the output end of the programmable power source; and the output ends of the variable resistance networks are electrically connected with the output control module. The automobile electronic and electrical performance test circuit system can meet multi-path pulse parameters required by automobile electronic and electrical performance test equipment, replace professional detection equipment, and reduce the construction cost of a testing process.

Description

technical field [0001] The invention relates to the technical field of electrical test circuit systems, in particular to an automotive electronic and electrical performance test circuit system. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] There are many electronic components and electrical systems in the car. Different electronic components work together in the same car. The voltage fluctuations generated when the components work normally will be transmitted to other electrical equipment through the cables in the car. Especially when the car is started, the voltage fluctuation of the car power supply system caused by the rectification will cause abnormalities in sensitive equipment. Therefore, the anti-interference ability of components to such voltage fluctuations is a crucial item in the car inspection process. The automotive electronic and elec...
