Abstract

A driving apparatus is controlled by using a driving command that is obtained by applying an accelerator operation amount to a relation between the accelerator operation amount and the driving command for the driving apparatus, and the relation is set by using a distribution of usage of the driving command by a driver such that a gradient that is a change in the driving command with a change in the accelerator operation amount in a high usage range including a value having a longest usage time among values of the driving command is less than the gradient in a range other than the high usage range.

First claim

What is claimed is:

1. A control system comprising:
a control unit configured to control a driving apparatus by using a driving command, the driving command being obtained by applying an accelerator operation amount to a relation between the accelerator operation amount and the driving command for the driving apparatus;
a relation setting unit configured to set the relation by using a usage time map that is a relation between the driving command and a usage time by a driver, such that a gradient that is a change in the driving command with a change in the accelerator operation amount in a high usage range including a value having a longest usage time among values of the driving command is less than the gradient in a range other than the high usage range; and
an authentication unit configured to authenticate a driver, wherein the relation setting unit is configured to set the relation by using a distribution of usage of the driving command by an authenticated person that is the driver authenticated by the authentication unit.

2. The control system according to claim 1 , wherein the relation setting unit is configured to set the high usage range to a range less than or equal to the value having the longest usage time among the values of the driving command or a value obtained by adding a margin to the value having the longest usage time among the values of the driving command.

3. The control system according to claim 1 , wherein the relation setting unit is configured to stabilize the gradient in the high usage range.

4. The control system according to claim 1 , wherein the control unit is configured to change the relation at startup of the control system.

5. The control system according to claim 1 , wherein:
the control system includes a first controller and a second controller that are configured to be capable of communicating with each other;
the control system further comprises a data collection unit configured to send a driver and the driving command to the second controller in association with each other;
the first controller includes the control unit and the data collection unit;
the second controller includes the relation setting unit; and
the relation setting unit is configured to set the distribution of usage and the relation by using the driver and the driving command, associated with each other, from the data collection unit and send the relation to the first controller.

6. A control system comprising:
a processor programmed to control a driving apparatus by using a driving command, the driving command being obtained by applying an accelerator operation amount to a relation between the accelerator operation amount and the driving command for the driving apparatus;
a server configured to set the relation by using a usage time map that is a relation between the driving command and a usage time by a driver, such that a gradient that is a change in the driving command with a change in the accelerator operation amount in a high usage range including a value having a longest usage time among values of the driving command is less than the gradient in a range other than the high usage range; and
a biometric authenticator configured to authenticate a driver, wherein the server is configured to set the relation by using a distribution of usage of the driving command by an authenticated person that is the driver authenticated by the biometric authenticator.
