Setting change assist apparatus

1. A setting change assist apparatus for a vehicle, comprising:

a controller configured to perform driving support control for the vehicle in accordance with a setting state of the driving support control;

an operating device, including a plurality of operating switches, configured to be operable by a driver of the vehicle, and used for an operation changing the setting state of the driving support control; and a notification device configured to notify the driver of information,

wherein the controller is further configured to:

execute voice recognition processing for recognizing an utterance of the driver,

determine whether a setting change request is issued by the utterance, the setting change request being a request for changing the setting state of the driving support control, and including a plurality of types of requests,

when determining through the voice recognition processing that the setting change request is issued by the utterance, determine a type of the issued setting change request, determine an approval operation that defines what and how one of the operating switches is to be operated in order for the driver to perform the approval operation based on the type of the issue setting change request, and cause the notification device to notify the driver of confirmation information including both information on a content of the setting change request issued by the utterance, and information on the determined approval operation, and

when the driver performs an operation corresponding to the information on the determined approval operation notified by the notification device by using the operating device, change the setting state of the driving support control in accordance with the setting change request

wherein the controller is configured to perform the driving support control when an operating state as the setting state is an on state, and stop the driving support control when the operating state is an off state,

the operating device comprises a first operating part to be operated for changing the operating state from the off state to the on state, and a second operating part to be operated for changing the operating state from the on state to the off state,

the setting change request comprises an on request which is a request for changing the operating state from the off state to the on state, and an off request which is a request for changing the operating state from the on state to the off state,

the controller is configured to:

when determining through the voice recognition processing that the on request is issued, determine an operation on the first operating part as the approval operation, and

when the operation on the first operating part is performed, change the operating state from the off state to the on state, and

the controller is configured to:

when determining through the voice recognition processing that the off request is issued, determine an operation on the second operating part as the approval operation, and

when the operation on the second operating part is performed, change the operating state from the on state to the off state

wherein the controller is configured to set, as the setting state, a value of a control parameter for support provided by the driving support control, and perform the driving support control in accordance with the value of the control parameter,

the operating device comprises a third operating part to be operated for increasing the value of the control parameter, and a fourth operating part to be operated for decreasing the value of the control parameter,

the setting change request comprises an increasing request which is a request for increasing the value of the control parameter, and a decreasing request which is a request for decreasing the value of the control parameter,

the controller is configured to:

when determining through the voice recognition processing that the increasing request is issued, determine an operation on the third operating part as the approval operation, and

when the operation on the third operating part is performed, increase the value of the control parameter in accordance with the increasing request, and

the controller is configured to:

when determining through the voice recognition processing that the decreasing request is issued, determine an operation on the fourth operating part as the approval operation, and

when the operation on the fourth operating part is performed, decrease the value of the control parameter in accordance with the decreasing request;

and wherein,

the driving support control is a cruise control including a constant speed travel control,

the value of the control parameter is a target speed used in the cruise control, and

the controller is further configured to:

determine that a speed increasing request as the increasing request is issued, at least when the recognized utterance of the driver includes a word related to the target speed and a numerical value related to the vehicle speed, the constant speed travel control is being performed, and the numerical value related to the vehicle speed included in the recognized utterance of the driver is higher than a speed of the vehicle at the present time, and

determine that a speed decreasing request as the decreasing request is issued, at least when the recognized utterance of the driver includes a word related to the target speed and a numerical value related to the vehicle speed, the constant speed travel control is being performed, and the numerical value related to the vehicle speed included in the recognized utterance of the driver is lower than the speed of the vehicle at the present time;

wherein the controller is further configured to,

when determining through the voice recognition processing that the setting change request is issued by the utterance, the operating switches other than the operating switches that is determined to be operated in order for the driver to perform the approval operation are disabled except the second operating part, and

in a case where the controller determines through the voice recognition processing that a request other than the off request is issued, when the driver performs the operation on the second operating part before performing the approval operation corresponding to the issued request, change the operating state from the on state to the off state.

2. The setting change assist apparatus according to claim 1 , wherein the controller is configured to, when determining through the voice recognition processing that two or more request are issued as the setting change request, determine an operation on one of the plurality of operating parts as the approval operation.

3. The setting change assist apparatus according to claim 1 , wherein the controller is configured to perform the driving support control when an operating state as the setting state is an on state, and stop the driving support control when the operating state is an off state,

the operating device comprises a first operating part to be operated for changing the operating state from the off state to the on state, and a second operating part to be operated for changing the operating state from the on state to the off state,

the setting change request comprises an on request which is a request for changing the operating state from the off state to the on state, and an off request which is a request for changing the operating state from the on state to the off state,

the controller is configured to:

when determining through the voice recognition processing that the on request is issued, determine an operation on the first operating part as the approval operation, and

when the operation on to the first operating part is performed, change the operating state from the off state to the on state, and

the controller is configured to:

when determining through the voice recognition processing that the off request is issued, change the operating state from the on state to the off state without requesting the driver to perform the approval operation.
