Vehicle control device and vehicle control method
A control switching unit inquires of a remote control center via a communication unit as to presence or absence of another vehicle traveling within a predetermined range including a host vehicle and being switchable from remote driving control to follow-up driving control when a communication quality detected by a communication quality detecting unit becomes less than a predetermined communication quality during the control of the driving of the host vehicle by a remote driving control unit. The control switching unit causes the remote driving control unit to continuously control the driving of the host vehicle when there is a response indicating presence of the another vehicle, and causes a follow-up driving control unit to control the driving of the host vehicle when there is a response indicating absence of another vehicle.
1. A vehicle control device, comprising:
processing circuitry configured to
communicate with a remote control center and receive remote control information for remotely controlling a first vehicle from the remote control center;
detect communication quality;
control driving of the first vehicle based on remote driving control using the remote control information;
control the driving of the first vehicle based on follow-up driving control so as to travel following a preceding vehicle traveling ahead of the first vehicle; and
take control of the driving of the first vehicle by switching the remote driving control and the follow-up driving control,
wherein the processing circuitry inquires of the remote control center via the communication as to presence or absence of a second vehicle traveling within a predetermined range including the first vehicle, the second vehicle being switchable from the remote driving control to the follow-up driving control, when the detected communication quality becomes less than a predetermined communication quality during the control of the driving of the first vehicle based on the remote driving control, and
the processing circuitry continuously controls the driving of the first vehicle based on the remote driving control when there is a response indicating absence of the second vehicle, and
the processing circuitry controls the driving of the first vehicle based on the follow-up driving control when there is a response indicating presence of the second vehicle.
2. The vehicle control device according to claim 1 ,
wherein the processing circuitry inquires of the remote control center via the communication as to presence or absence of the second vehicle traveling within the predetermined range and being switchable from the remote driving control to the follow-up driving control when the detected communication quality before controlling the driving of the first vehicle based on the remote driving control is less than the predetermined communication quality, and
the processing circuitry controls the driving of the first vehicle based on the remote driving control when there is a response indicating presence of the corresponding second vehicle, and
the processing circuitry controls the driving of the first vehicle based on the follow-up driving control when there is a response indicating absence of the corresponding second vehicle.
3. The vehicle control device according to claim 1 ,
wherein when the processing circuitry receives an instruction to switch from the remote driving control to the follow-up driving control, the instruction being transmitted from the remote control center during the control of the driving of the first vehicle based on the remote driving control, and the preceding vehicle is present, the processing circuitry controls the driving of the first vehicle based on the follow-up driving control and notifies the remote control center of switching completion, and
when the processing circuitry receives the instruction, and the preceding vehicle is not present, the processing circuitry continuously controls the driving of the first vehicle based on the remote driving control and notifies the remote control center of unswitchability.
4. A vehicle control method of a vehicle control device including: processing circuitry configured to communicate with a remote control center and receive remote control information for remotely controlling a first vehicle from the remote control center; detect communication quality; control driving of the first vehicle based on remote driving control using the remote control information; control the driving of the first vehicle based on follow-up driving control so as to travel following a preceding vehicle traveling ahead of the first vehicle; and take control of the driving of the first vehicle by switching the remote driving control or the follow-up driving control, the vehicle control method comprising:
inquiring of the remote control center via the communication as to presence or absence of a second vehicle traveling within a predetermined range including the first vehicle, the second vehicle being switchable from the remote driving control to the follow-up driving control, when the detected communication quality becomes less than a predetermined communication quality during the control of the driving of the first vehicle based on the remote driving control;
continuously controlling the driving of the first vehicle based on the remote driving control when there is a response indicating presence of the second vehicle; and
controlling the driving of the first vehicle based on the follow-up driving control when there is a response indicating absence of the second vehicle.
