The invention discloses an automatic driving navigation positioning precision evaluation method based on
map matching. The method comprises the following steps that: a vehicle-mounted sensor transmitsa vehicle real-
time signal to a vehicle real-
time signal collection module, the vehicle real-
time signal collection module transmits a collected
electric signal to a
processing module, map data is transmitted to the
processing module at the same time, the
processing module transmits comparison data to a
central processing unit through a transmission module, the central processing module processesdata comparison information in a centralized mode, takes out effective information and transmits the effective information to an evaluation module, a judgment module judges evaluation information generated by the evaluation module, a secondary judgment module judges information processed by the judgment module, the secondary judgment module transmits and feeds back a judgment
signal to the central processing module, the central processing module integrates and processes information and transmits the information to a misjudgment
signal detection module for final
signal judgment, and finally, final result data is transmitted through a processing result feedback module. According to the invention, the positioning precision and safety of an automatic driving automobile can be improved.
