Driverless electric automobile power supply system based on super capacitance

Abstract

The invention relates to an unmanned electric automobile power system based on super capacitance, and belongs to the unmanned vehicle technology field. The invention consists of a super capacitor bank, an intelligent charger, a super capacitance management system, a first direct-current transferring power module, a second direct-current transferring power module, a vehicle computer control systemand a DSP control system. The supper capacitor bank is connected with the super capacitance management system and the first direct-current transferring power module. The second direct-current transferring power module and a driving motor in the automobile are connected with a steering motor and the intelligent charger. The first direct-current transferring power module is connected with a vehiclecomputing control system. The vehicle computing system is connected with the DSP control system through CAN communication. The second direct-current transferring power module is connected with the vehicle transducer of the automobile, the DSP control system and a vehicle auxiliary device separately. The output end of the DSP control system is connected with the driving system of the automobile. The DSP control system is connected with the super capacitance management system through the CAN communication. The invention has small volume and simple structure. And the zero pollution of vehicles isachieved.

Description

technical field [0001] The invention relates to a system in the technical field of vehicles, in particular to a supercapacitor-based unmanned electric vehicle power supply system. Background technique [0002] The control system of an unmanned electric vehicle is relatively complex, and the vehicle is equipped with a control computer, laser radar, automatic navigation equipment and various sensors. They have relatively large requirements for power supply, and there are many types of voltages. If the battery is used for power supply, when the vehicle starts or accelerates, the driving 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. Work. At present, the existing unmanned electric vehicles are usually powered by batteries, mainly lead-acid batteries and nickel-metal hydride batteries. The disad...
