Verification of smart guiding system to search for parking space via DSRC communication

摘要

A traditional parking field is managed by manpower, and perhaps there are also plenty of advanced areas which are auxiliary installed or embedded with IR equipment or marked lines. However, this kind of state is constrained with limit service and bounded. This paper presents an innovative concept of services for parking guidance. Driver can make a reservation by smart phone or tablet pc in thirty minutes before, and furthermore the service platform will book a parking lot using vehicle ID. When vehicle pass through the entrance of parking area, the location of reserved parking lot will be marked in a customized map and transmitted to in-vehicle device using DSRC. After driver parks his vehicle to scheduled parking lot, parking server will send a message to driver or in-vehicle device in order to log the final vehicle location and heading. The developed system, which is named as SmartValet, is also available in underground parking area or interior of the building. The autonomous ability is integrated different sensors to offer robots or remotely operated systems a reliable navigation means. It addresses a global and all weather navigation design based on GPS, gear-box speed, odometry and inertial measurement in dead reckoning and data fusion. Positioning uncertainty will grow with time as a result of integration error so the performance will lose accuracy. To solve this shortcoming with error bounded, this paper uses a creative idea which driver clicks and drags touch panel to give a new position and heading. The proposed system which utilizes DSRC devices, inertial sensors and vehicle network information is implemented with theoretical application and hardware integration, and furthermore the result shows navigation ability and approach applicability.
