Abstract

The invention relates to an anti-interference power system of unmanned electric vehicle, wherein the invention comprises kenotron, 220V interver, assist accumulator, main accumulator, sensor power source, control board power source, computer power source, and motor driver. The anode of kenotron is connected to the anode of main accumulator, while its cathode is connected to the anode of assist accumulator and the input anode of inverter; the cathode of main accumulator is connected to the cathode of assist accumulator and the input cathode of inverter; the motor driver is connected to two ends of main accumulator; the inputs of sensor power source, control board power source and the computer power source are connected to the output of inverter. The invention can avoid interfering voltage of main accumulator to save cost and avoid charging assist accumulator lonely.

Description

technical field [0001] The invention relates to a power supply system in the technical field of vehicles, in particular to an anti-jamming power supply system of an unmanned electric vehicle. technical background [0002] The anti-interference power supply system of unmanned electric vehicles is a research in the field of vehicle technology, and it is a key technology for the stable and reliable driving of vehicles. Driverless electric vehicles are generally powered by batteries. When the vehicle starts or accelerates, the motor on the vehicle will cause large fluctuations in the voltage of the battery, which will cause great interference to the control system of the unmanned electric vehicle, and in severe cases, the vehicle will not work normally. At present, the usual way to prevent power fluctuations and anti-interference is to add a DC / DC converter between the battery and the vehicle controller for voltage stabilization and voltage conversion, and at the same time add ...
