Embodiment Construction
[0016] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.
[0017] The present invention is a road network hacker vehicle positioning method based on a dedicated short-range communication network, comprising the following steps:
[0018] Step 1: Collect the acceleration values of vehicles in the road network when they encounter typical traffic events. Typical traffic events include: encountering traffic lights at intersections, overtaking, following cars, etc., collecting special short-range communication signals in the road network in the two workshops Propagated transmit power and receive power, and record the relative distance between vehicles;
[0019] Step 2. Based on the acceleration value collected in step 1, the transmission power and reception power value of the dedicated short-range communication signal between the two workshops, and the relative distance value, a set of dynamic acceleration values...
