摘要： A method for controlling operation of a motor vehicle includes an electronic controller receiving, e.g., from a vehicle-mounted sensor array, sensor data with dynamics information for a target vehicle and, using the received sensor data, predicting a lane assignment for the target vehicle on a road segment proximate the host vehicle. The electronic controller also receives map data with roadway information for the road segment; the controller fuses the sensor and map data to construct a polynomial overlay for a host lane of the road segment across which travels the host vehicle. A piecewise linearized road map of the host lane is constructed and combined with the predicted lane assignment and polynomial overlay to calculate a lane assignment for the target vehicle. The controller then transmits one or more command signals to a resident vehicle system to execute one or more control operations using the target vehicle's calculated lane assignment.

摘要： A map matching method, an apparatus and an electronic device related to the technical field of artificial intelligence such as high-precision map, autonomous driving, internet of vehicles, and smart cockpit, where a specific implementation is: when matching a high-precision map with a standard-precision map, firstly acquire road network data corresponding to the high-precision map and the standard-precision map to be matched; and construct a first graph network based on the road network data corresponding to the high-precision map, and construct a second graph network based on the road network data corresponding to the standard-precision map, then determine a matching result between the high-precision map and the standard-precision map based on the first graph network and the second graph network. By the method using the graph network, the matching of the high-precision map with the standard-precision map can be accurately realized, thereby effectively improving accuracy of the matching result.
