Abstract

The invention relates to an on-board diagnostics (OBD) equipment power supply circuit, a control method of the OBD equipment power supply circuit and an OBD simulator. The OBD equipment power supply circuit comprises a power supply, a voltage converter, a digital potentiometer, a controller and a memory. When the OBD equipment power supply circuit works, the controller can obtain a preset programstored in the memory and control the digital potentiometer to work. When the digital potentiometer works, the voltage converter can be adjusted, so that the voltage of a second electric signal outputby the voltage converter is controlled. According to the OBD equipment power supply circuit, the voltage of the output second electric signal can be automatically adjusted according to a preset program, so that different states of an automobile are simulated to supply power to OBD equipment. According to the OBD equipment power supply circuit, manual control of a user is not required, and the useconvenience of the OBD simulator using the OBD equipment power supply circuit can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle electronics, in particular to an OBD equipment power supply circuit, a control method thereof, and an OBD simulator. Background technique [0002] When the car is in different working states such as stop, run and sleep, the voltage of its power system is also different. OBD (On-Board Diagnostic, on-board diagnostic system) equipment can be used to detect different working states and voltage data of the car. [0003] The OBD simulator is used to simulate the car's OBD port to supply power to the OBD device. In traditional technology, the output voltage of the OBD device is usually manually controlled by the user. [0004] In the process of realizing the traditional technology, the inventor found that: the traditional OBD simulator requires manual control by the user, and the use process is not convenient enough. Contents of the invention [0005] Based on this, it is necessary to provide an OB...
