Description

Control mode switching device for vehicle Technical Field The present invention relates to a control mode switching device for a vehicle such as an automobile. Background A control mode switching device is known that switches a control mode of a vehicle by operating an operation element in the vehicle such as an automobile. For example, patent document 1 below describes a control mode switching device that switches a running mode of a vehicle between an electric mode and a hybrid mode and switches a gear stage of an automatic transmission by operating a lever of a shift lever. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2022-72666 Disclosure of Invention [ Problem to be solved by the invention ] In the control of a vehicle such as an automobile, there are cases where the control mode is switched to a non-control mode in which the control amount does not automatically change, an automatic mode in which the control amount automatically changes, and a manual mode in which the control amount manually changes. In the conventional control mode switching device such as the device described in patent document 1, when the control mode is switched between the three modes by operating one or one of the operating devices such as the lever of the shift knob, the operation of the operating device is inevitably complicated. Therefore, when the control mode is switched, a malfunction of the operation device is liable to occur. The invention provides a control mode switching device for a vehicle, which is improved to be more difficult to cause misoperation of an operating device when switching control modes among three modes compared with a conventional control mode switching device. [ Effects of the invention and the solution to the problems ] According to the present invention, a control mode switching device (100) for a vehicle is provided that switches a control mode between a non-control mode in which a control amount does not automatically change, an automatic mode in which the control amount automatically changes, and a manual mode in which the control amount manually changes. The control mode switching device includes first and second operation devices (24, 18) operated by a driver, and a control unit (10) configured to switch a control mode based on the operation of the first and second operation devices, the control unit being configured to switch the control mode between two of the three modes to set a basic mode (80, 82) based on the operation of the first operation device (24), and to switch the control mode between the remaining modes other than the two of the three modes and the basic mode based on the operation of the second operation device (18). According to the above configuration, two modes out of the three modes are set as the basic mode, and the control mode is switched between the two modes based on the operation of the first operation device. Thereby, the driver can switch the control mode between the two modes as the basic mode by operating the first operating device. In addition, according to the above configuration, the control mode is switched between the remaining mode other than the two modes and the basic mode based on the operation of the second operation device. Thereby, the driver can switch the control mode between the remaining mode and the basic mode by operating the second operating device. Thus, according to the above configuration, the possibility of erroneous operation of the operation device when the control mode is switched between the three modes can be reduced as compared with the conventional device in which the control mode is switched between the three modes by operating one or one of the operation devices. [ Technical solution of the invention ] In one aspect of the present invention, the second operating device (18) is provided at a position that is easily contacted by the driver during driving of the vehicle as compared with the first operating device (24). According to the above-described aspect, the driver can easily operate the second operating device during driving of the vehicle, as compared with the first operating device. This makes it possible to easily switch the control mode between the remaining mode and the basic mode, as compared with the switching of the control mode between the two modes set as the basic mode. In another aspect of the invention, the operation of the second operating means (18) for switching the control mode between the remaining mode and the base mode is the same, regardless of which of the two modes the base mode is. According to the above-described aspect, the switching of the control mode between the remaining mode and the basic mode can be easily performed, as compared with the case where the operation of the second operation device is different depending on which of the two modes the basic mode is. In still another aspect of the present invention, the control unit (10) is configured
