Abstract

A driving handover control device includes a memory and a processor coupled to the memory. In a case in which driving is handed over from a first state in which a vehicle travels in accordance with instruction from a first remote operator of the vehicle to a second state in which the vehicle travels in accordance with instruction from a second remote operator who is different from the first remote operator, the processor implements a transition from the first state to a third state in which the vehicle travels autonomously without instruction from the first remote operator or the second remote operator, and, after the transition from the first state to the third state, implements a transition from the third state to the second state.

First claim

The invention claimed is:

1. A driving handover control device, comprising:
a memory; and
a processor coupled to the memory, the processor being configured to:
in a case of a driving handover from a first state in which a vehicle travels in accordance with instruction from a first remote operator of the vehicle to a second state in which the vehicle travels in accordance with instruction from a second remote operator who is different from the first remote operator, implement a transition from the first state to a third state, in the third state the vehicle traveling by a fully autonomous driving mode, and
after the transition from the first state to the third state, implement a transition from the third state to the second state.

2. The driving handover control device of claim 1 , wherein the processor is configured to implement a transition from the first state to the third state in a case in which the first remote operator has requested that driving in the first state be ended.

3. The driving handover control device of claim 1 , wherein the processor is configured to implement a transition from the first state to the third state in a case in which a preset condition for ending driving in the first state has been met.

4. The driving handover control device of claim 1 , wherein the processor is configured to implement a transition from the first state to the third state in a case in which an abnormality in driving in the first state has been detected.

5. The driving handover control device of claim 1 , wherein the processor is configured to:
in a case of a driving handover from the first state to the second state, notify the second remote operator of the driving handover during the third state, and
in a case in which the second remote operator has indicated acceptance in response to being notified, implement a transition from the third state to the second state.

6. A driving handover control method, comprising:
by a processor,
in a case of a driving handover from a first state in which a vehicle travels in accordance with instruction from a first remote operator of the vehicle to a second state in which the vehicle travels in accordance with instruction from a second remote operator who is different from the first remote operator, implementing a transition from the first state to a third state, in the third state the vehicle traveling by a fully autonomous driving mode, and
after the transition from the first state to the third state, implementing a transition from the third state to the second state.

7. A non-transitory computer-readable recording medium storing a program executable by a computer to perform driving handover control processing, the driving handover control processing comprising:
in a case of a driving handover from a first state in which a vehicle travels in accordance with instruction from a first remote operator of the vehicle to a second state in which the vehicle travels in accordance with instruction from a second remote operator who is different from the first remote operator, implementing a transition from the first state to a third state, in the third state the vehicle traveling by a fully autonomous driving mode, and
after the transition from the first state to the third state, implementing a transition from the third state to the second state.
