Claim 9:
10. A route planning method, comprising:
receiving a route planning request from a user, the route planning request comprising a line of interest on a map;
identifying the line of interest in response to the route planning request;
acquiring road and traffic information associated with the line of interest from a road and traffic data source; and
calculating, based on the acquired road and traffic information, a navigation route that matches or corresponds to the line of interest and meets or satisfies predefined road and traffic constraints;
wherein the route planning method is performed in a running autonomous vehicle (AV) and further comprises:
acquiring, from one or more sensors on the running AV, real-time sensor data to be fed into a safety driving model;
calculating the navigation route that matches or corresponds to the line of interest and meets or satisfies both the road and traffic constraints and predefined safety driving constraints;
simulating route changing along the line of interest in response to the route planning request;
determining whether the route changing violates the safety driving constraints;
rejecting the route planning request when it is determined the route changing violates the safety driving constraints; and
accepting the route planning request and calculating the navigation route under the road and traffic constraints when it is determined the route changing does not violate the safety driving constraints.
