Vehicle control device and vehicle control system
There are provided a vehicle control device and a vehicle control system capable of improving efficiency and reliability of auto valet parking compared to the related art when a communication failure occurs. A vehicle control device mounted on a vehicle includes a recognition unit, an estimation unit, a communication unit, a determination unit, a trajectory generation unit, a vehicle control unit, and a retreated position decision unit. When the determination unit determines that communication of the communication unit is abnormal, the trajectory generation unit generates a target trajectory along which the vehicle drives to a retreated position decided by the retreated position decision unit.
1. A vehicle control device mounted on a vehicle, the device comprising:
a recognition unit that recognizes a driving environment around the vehicle;
an estimation unit that estimates a position of the vehicle based on the driving environment;
a communication unit that communicates with an external facility of the vehicle;
a determination unit that determines whether or not a failure occurs in the communication;
a trajectory generation unit that generates a target trajectory along which the vehicle autonomously drives;
a vehicle control unit that causes the vehicle to drive along the target trajectory; and
a retreated position decision unit that decides a retreated position of the vehicle based on the communication and the driving environment,
wherein the trajectory generation unit generates the target trajectory along which the vehicle drives to the retreated position when the determination unit determines that the communication is abnormal; and
wherein
the retreated position decision unit transmits the retreated position to the external facility via the communication unit, and
the trajectory generation unit generates the target trajectory along which the vehicle drives to the retreated position transmitted to the external facility immediately before the determination when the determination unit determines that the communication is abnormal.
2. The vehicle control device according to claim 1 , wherein the communication unit reduces a period of the communication at an intersection of paths along which the vehicle drives.
3. The vehicle control device according to claim 1 , wherein the determination unit reduces a period of the determination at an intersection of paths along which the vehicle drives.
4. The vehicle control device according to claim 1 , wherein the vehicle control unit decelerates the vehicle at an intersection of paths along which the vehicle drives.
5. The vehicle control device according to claim 1 , further comprising:
an inter-vehicle communication unit that performs communication between the vehicle and another vehicle,
wherein the inter-vehicle communication unit transmits a position and a speed of the vehicle to the other vehicle when the determination unit determines that the communication of the communication unit is abnormal.
6. A vehicle control system comprising:
the vehicle control device according to claim 1 ; and
a management center that manages the vehicle,
wherein the management center includes a center communication unit that communicates with the communication unit, a storage device that has map information of a parking lot that the vehicle is moved in and out, and a computing device that decides a parking position of the vehicle.
7. The vehicle control system according to claim 6 , wherein
the computing device includes a center determination unit that determines whether or not a failure occurs in the communication with the vehicle,
the center communication unit receives the retreated position transmitted from the vehicle via the communication unit,
the storage device records the retreated position received by the center communication unit, and
the computing device estimates, as a position of the vehicle, the retreated position stored in the storage device immediately before the determination when the center determination unit determines that the communication is abnormal.
