Vehicle traveling speed alert providing method

The invention provides a vehicle traveling speed alert providing method. The method includes that satellite signals received are calculated by the aid of a processing unit of a global positioning satellite navigation device to acquire the speed and position of a vehicle, the processing unit compares the vehicle position with road speed limit information in a data access device to acquire road speed limits of the position where the vehicle is located, the vehicle speed is compared with the road speed limits of the position where the vehicle is located, the processing unit is utilized to send signals to allow a reporting unit to send an alert to notify a driver when the vehicle speed exceeds the road speed limits, the driver is prevented from overspeeding the vehicle by accident, traffic safety during vehicle traveling can be improved, and accident occurrence can be avoided. 本发明提供种车辆行进速度的警讯提供方法，所述警讯提供方法为利用全球卫星定位导航装置的处理单元将所接收到的卫星信号进行计算，从而得到车辆的速度与位置，且处理单元以车辆位置与资料存取装置中的道路限速资料进行比对后得到车辆所在道路限速，再将车速与车辆所在道路限速进行比对，即可在车速
