Abstract

The invention relates to the technical field of automatic driving vehicles, and discloses a multi-path power supply circuit and device and an automatic driving vehicle. The multi-path power supply circuit comprises a first overload protection module, a voltage stabilization control module, a second overload protection module and an output interface module, wherein the first overload protection module is connected with the power supply and the voltage stabilization control module, the voltage stabilization control module is connected with the second overload protection module, the second overload protection module is connected with the output interface module, and the output interface module is connected with corresponding connecting equipment. The first overload protection module and the second overload protection module guarantee the use safety of connecting equipment and power supply voltage, the voltage stabilization control module outputs different power supply voltage in multiplepaths, the output interface module provides multiple paths of voltage output, different power utilization requirements of the connecting equipment can be met, the power supply equipment is prevented from directly outputting large current to whole vehicle equipment when breaking down, and the safety of the multi-path power supply equipment is improved.

Description

technical field [0001] The invention relates to the technical field of automatic driving vehicles, in particular to a multi-channel power supply circuit, device and automatic driving vehicle. Background technique [0002] With the development of self-driving technology, self-driving vehicles have appeared in the vast market, and the power supply system of self-driving vehicles is an important part of reflecting the performance of self-driving vehicles. At present, the power supply system of self-driving vehicles often adopts the DC-DC method. The main process is to use the power stored in the large battery of the self-driving vehicle to convert the high-voltage direct current of the large battery into low-voltage direct current for step-down processing. Therefore, it becomes a safe voltage in line with the normal use of the equipment, but this method requires a customized controller, and the production is cumbersome, and there is a certain safety risk for current control.
