Embodiment Construction
[0077] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0078] An electronic map-based vehicle collision warning method is based on the sharing and exchange of vehicle motion state information and location information between the vehicle and neighboring vehicles, and combines the electronic map information to assist collision warning, and finally the human-machine interface HMI informs the driver of the alarm information. Such as figure 1 , figure 2 As shown, the method of the present invention specifically includes the following steps:
[0079] 1) Obtain the GPS data of the vehicle. The GPS data includes motion state information and position information, and use coordinate system conversion to map the vehicle position information (ie the GPS coordinates of the vehicle and the received GPS coordinates of other vehicles) to a two-dimensional rectangular coordinate system , Where the motion status information include...
