Abstract

Provided is a system for generating a recommended driving lane based on a general-purpose map with improved real-time property for updating. A vehicle control system 1 for controlling a vehicle 2 during autonomous driving thereof, comprises a vehicle control unit 3 and a mobile terminal 5. The vehicle control unit 3 acquires travel control map data from a first map server 4 and transmits position data of the vehicle 2 to the mobile terminal 5. The mobile terminal 5 acquires navigation map data containing lane information on lanes forming each road section from a second map server 6, generates, based on the lane information and the position data of the vehicle 2, driving route information including a recommended driving lane which should be selected on a priority basis as a driving lane for the vehicle, and transmits the driving route information to the vehicle control unit 3.

First claim

1 . A vehicle control method for controlling a vehicle based on map information during autonomous driving of the vehicle, the method being performed by a vehicle control system, wherein the vehicle control system comprises:
a vehicle control unit mounted in the vehicle, wherein the vehicle control unit is configured to acquire travel control map data from a first map server, the travel control map data being data of a travel control map used for travel control, and perform the travel control of the vehicle based on the travel control map; and a mobile terminal communicatively connected to the vehicle control unit, wherein the mobile terminal is configured to acquire navigation map data from a second map server, the navigation map data being data of a navigation map for route navigation, and provide the vehicle control unit with driving route information on a driving route in the navigation map, wherein the navigation map contains lane information on a lane(s) forming each road section, wherein the vehicle control unit is configured to transmit position data of the vehicle to the mobile terminal, and wherein the mobile terminal is configured to: based on the lane information and the position data of the vehicle received from the vehicle control unit, generate the driving route information including recommended lane information about a recommended driving lane which should be selected on a priority basis as a driving lane for the vehicle; and transmit the driving route information including the recommended lane information to vehicle control unit.

2 . The method according to claim 1 , wherein the mobile terminal is configured to:
sequentially receive the multiple position data of the traveling vehicle from the vehicle control unit; update the driving route information including the recommended lane information based on the latest position data of the vehicle; and transmit the updated driving route information to the vehicle control unit.

3 . The method according to claim 1 , wherein the travel control map data includes dynamically changeable information which is not included in the navigation map data and can change with time in a more dynamic manner than that included in the navigation map data, and
wherein the dynamically changeable information includes at least one type of information selected from signal information, nearby vehicle information, and pedestrian information.

4 . The method according to claim 1 , wherein the vehicle control unit is configured to request the first map server to transmit the travel control map data based on the driving route information including the recommended lane information.

5 . The method according to claim 1 , wherein the mobile terminal is configured to calculate an estimated arrival time when the vehicle will arrive at an end point of the driving route based on the driving route information including the recommended lane information, and transmit the estimated arrival time to the vehicle control unit.

6 . The method according to claim 1 , wherein the mobile terminal is configured to acquire sensor measurement data from the vehicle control unit, the sensor measurement data being acquired by a sensor for measuring a remaining amount of battery or fuel used for driving of the vehicle, and
determine the driving route based on the sensor measurement data.

7 . A vehicle control system for controlling a vehicle based on map information during autonomous driving of the vehicle, the system comprising:
a vehicle control unit mounted in the vehicle, wherein the vehicle control unit is configured to acquire travel control map data from a first map server, the travel control map data being data of a travel control map used for travel control, and perform the travel control of the vehicle based on the travel control map; and a mobile terminal communicatively connected to the vehicle control unit, wherein the mobile terminal is configured to acquire navigation map data from a second map server, the navigation map data being data of a navigation map for route navigation, and provide the vehicle control unit with driving route information on a driving route in the navigation map, wherein the navigation map contains lane information on a lane(s) forming each road section, wherein the vehicle control unit is configured to transmit position data of the vehicle to the mobile terminal, and wherein the mobile terminal is configured to: based on the road information and the position data of the vehicle received from the vehicle control unit, generate the driving route information including recommended lane information about a recommended driving lane which should be selected on a priority basis as a driving lane for the vehicle; and transmit the driving route information including the recommended lane information to vehicle control unit.
