Abstract

A vehicle control system for controlling a vehicle is configured to perform automated driving by switching between a plurality of automated driving modes. The plurality of automated driving modes include: a first automated driving mode that does not require a driving operation by a human; and a second automated driving mode that requests an operation or monitoring by a human as necessary. In the first automated driving mode, the vehicle control system determines that there is human intervention when an operation state of an operating member operable by a human satisfies a first condition. In the second automated driving mode, the vehicle control system determines that there is human intervention when the operation state of the operating member satisfies a second condition. The first condition is less likely to be satisfied than the second condition.

First claim

What is claimed is:

1 . A vehicle control system for controlling a vehicle, the vehicle control system comprising:
one or more processors configured to perform automated driving by switching between a plurality of automated driving modes, wherein the plurality of automated driving modes include:
a first automated driving mode that does not require a driving operation by a human; and
a second automated driving mode that requests an operation or monitoring by the human as necessary,
in the first automated driving mode, the one or more processors are configured to determine that there is human intervention in response to an operation state of an operating member operable by a human satisfying a first condition, in the second automated driving mode, the one or more processors are configured to determine that there is human intervention in response to the operation state of the operating member satisfying a second condition, the first condition is less likely to be satisfied than the second condition, in response to determining that there is the human intervention in the first automated driving mode, the one or more processors are configured to start a fail operation as a type of the automated driving without terminating the automated driving, and in response to determining that there is the human intervention in the second automated driving mode, the one or more processors are configured to terminate the automated driving.

2 . The vehicle control system according to claim 1 , wherein
the first condition includes that an operation amount or an operation time of the operating member exceeds a first threshold value, the second condition includes that the operation amount or the operation time of the operating member exceeds a second threshold value, and the first threshold value is greater than the second threshold value.

3 . The vehicle control system according to claim 1 , wherein the operating member is a steering wheel, a brake pedal, or an accelerator pedal.

4 . The vehicle control system according to claim 1 , wherein
the fail operation, when the operating member is a steering wheel, is to evacuate the vehicle to a predetermined position, and the fail operation, when the operating member is a brake pedal, is to stop the vehicle.

5 . A vehicle control system for controlling a vehicle,
the vehicle control system comprising one or more processors configured to perform automated driving by switching between a plurality of automated driving modes, wherein: the plurality of automated driving modes include:
a first automated driving mode that does not require a driving operation by a human; and
a second automated driving mode that requests an operation or monitoring by a human as necessary,
in the first automated driving mode, the one or more processors are configured to determine that there is human intervention when an operation state of an operating member operable by a human satisfies a first condition, in the second automated driving mode, the one or more processors are configured to determine that there is human intervention when the operation state of the operating member satisfies a second condition, and the first condition is less likely to be satisfied than the second condition, when determining that there is the human intervention in the first automated driving mode, the one or more processors start a fail operation, when determining that there is the human intervention in the second automated driving mode, the one or more processors terminate the automated driving, the fail operation, when the operating member is a steering wheel, is to evacuate the vehicle to a predetermined position, and the fail operation, when the operating member is a brake pedal, is to stop the vehicle.
