Regarding the system.

2. Description of the Related Art Electric vehicles such as electric wheelchairs and electric carts are sometimes provided with an operating device having a pair of handles spaced apart from each other in the vehicle width direction in order to control a drive device used for traveling operation. A user of an electric vehicle typically operates the steering wheel while holding the handle with both hands, and the electric vehicle is capable of various running operations by controlling the drive device in response to this operation. .

Furthermore, the operating device may include ancillary operating means, for example, a switch, in addition to the handle, so that more types of travel operations are possible. Preferably, the switch is operable by a user's hand holding the handle. Therefore, the switch is often located around the handle.

An example of an operating device having such a handle and a switch is an operation assisting device provided on the handle grip along the grip collar of the handle grip, which is a rod-shaped member. Such an operation assisting device has a device main body formed in the shape of a brim along the grip brim, and an operating switch that can be operated with a fingertip is arranged on an operating surface that is a circumferential curved surface of the device main body. Such operation switches are push switches, tactile switches, or directional switches. (For example, see Patent Document 1.)

Japanese Patent Application Publication No. 2015-184870

However, as in the example of the operating device described above, a switch that is a push switch, tactile switch, or directional switch can be turned on even when operated with a small force. Therefore, even if the user's hand, especially the user's hand holding the handle, accidentally slightly contacts the switch, the switch may turn on against the user's intention. That is, the switch is more likely to be erroneously operated, and furthermore, the operating device is more likely to be erroneously operated.

In order to prevent erroneous operation of the switch, it is conceivable to set the force required to turn the switch on to a larger value. However, when the electric vehicle is an electric wheelchair, an electric cart, etc., the users who use such an electric vehicle are mainly elderly people with weak physical strength. It is often difficult for such users to operate the switch with great force. In this case, there is a possibility that the operating device cannot be operated efficiently.

In view of these circumstances, it is desired that an operating system for an electric vehicle enable efficient operation and efficiently prevent erroneous operations.
