| Summary: | 碩士 === 國立成功大學 === 工程科學系 === 87 === The Autonomous Vehicle''s power source is battery. The battery''s voltage is 12V and if paiallel can become 24V. The Autonomous Vehicle uses voltage source not only 12V or 24V but also uses 5V or 15V. This paper is used DC-DC Converter way to get 5V or 15V.
The battery has certain capacity. When the battery is used, the voltage and capacity also is changed. If certain is expended or voltage lowers to much, the Autonomous Vehicle''s component can not use normal and error signal. Result the Autonomous Vehicle can not control. If the battery''s voltage and capacity is given to understand at any time, then the output ways have differ when the battery output voltage has imparity. This paper is design observation-system for the battery''s voltage and capacity. If the voltage or capacity lowers over set values, the output voltage can lower and use stage. When the voltage or capacity lowers over to be incapable of values, the output voltage can be closed.
