Abstract

An autonomous driving device includes an acquisition unit configured to acquire a value corresponding to a steering operation during an autonomous driving, and a control unit configured to perform the autonomous driving and to control switching of a driving state between the autonomous driving and a manual driving. In a case where a first value corresponding to the steering operation is equal to or greater than a first threshold value and a second value corresponding to the steering operation before the driving state is switched from the autonomous driving in progress to the manual driving is equal to or greater than a second threshold value, the control unit decelerates the vehicle and switches the driving state from the autonomous driving in progress to the manual driving.

First claim

What is claimed is:

1. An autonomous driving device configured to perform autonomous driving of a vehicle, and to switch a driving state from the autonomous driving in progress to manual driving in a case where a first value corresponding to a steering operation by a driver during the autonomous driving is equal to or greater than a first threshold value, the device comprising:
a processor configured to:
acquire a value corresponding to the steering operation during the autonomous driving;
perform the autonomous driving; and
control the switching of the driving state between the autonomous driving and the manual driving,
wherein, in a case where the first value corresponding to the steering operation equal to or greater than the first threshold value and a second value corresponding to the steering operation acquired before the driving state is switched from the autonomous driving in progress to the manual driving is equal to or greater than a second threshold value, the processor is configured to decelerate the vehicle and switch the driving state from the autonomous driving in progress to the manual driving.

2. The autonomous driving device according to claim 1 , wherein the first value corresponding to the steering operation and the second value corresponding to the steering operation are the same values, and the second threshold value is greater than the first threshold value.

3. The autonomous driving device according to claim 1 , wherein the first threshold and the second threshold are different values.

4. The autonomous driving device according to claim 1 , wherein the first value is selected from at least one of a steering torque, a steering angle, and a pressure on a steering device, and the second value is selected from at least one of a steering torque, a steering angle, and a pressure on a steering device.

5. An autonomous driving device configured to perform autonomous driving of a vehicle, comprising:
a processor configured to:
acquire a value corresponding to a steering operation during the autonomous driving;
perform the autonomous driving; and
control a switching of a driving state between the autonomous driving and a manual driving,
wherein, in response to a first value corresponding to the steering operation is equal to or greater than a first threshold, the processor is configured to decelerate the vehicle, and
wherein, in response to a second value corresponding to the steering operation acquired before the driving state is switched from the autonomous driving in progress to the manual driving is equal to or greater than a second threshold value, the processor is configured to switch the driving state from the autonomous driving in progress to the manual driving.

6. The autonomous driving device according to claim 5 , wherein the first threshold and the second threshold are different values.
