碩士 === 國立彰化師範大學 === 車輛科技研究所 === 95 === In this thesis, the research integrates the embedded development platform, residual capacity for Leas-Acid Batteries, 3.5G, GPS and CAN Bus to implement a driving mileage estimation for electric scooter. The systematic structure can be divided into two subsystems, calculation of driving mileage estimation for electric scooter and Road-Side emergency Service. The implementation of driving mileage estimation for electric scooter utilizes embedded developing platform to fetch outside signals and combined Coulometric measurement method to estimate the remaining driving distance according to present speed. When the remaining driving distance is not enough, the road-side emergency service will transmit message through CAN Bus to warning system. If the electric scooter can not drive any more, the embedded development platform will transmit message through 3.5G wireless communication to service server. The transmit message include electric scooter ID, longitude and latitude. The service serve utilizes electronic map to find out the electronic driver's position. It will notice the closest service station to support emergency service.
