CROSS-REFERENCE TO RELATED APPLICATIONS

The present disclosure claims priority to Japanese Patent Application No. 2018-004303 filed Jan. 15, 2018, which is incorporated herein by reference in its entirety including specification, drawings and claims.

TECHNICAL FIELD

The present disclosure relates to a motor vehicle.

BACKGROUND

A proposed configuration of a motor vehicle causes an output signal from a shift sensor that detects the operating position of a shift lever to be input into a plurality of CPUs (as described in, for example, JP 2017-067255A). When an abnormality occurs in part of the CPUs, the motor vehicle of this configuration causes the remaining CPU to identify the shift position based on the output signal from the shift sensor and performs emergency drive based on the identified shift position.

SUMMARY

The motor vehicle described above can be driven when any CPU among the plurality of CPUs is enabled to recognize the output signal from the shift sensor. When all the CPUs fail to recognize the output signal from the shift sensor, however, the above motor vehicle cannot be driven.

A main object of the present disclosure is to enable a motor vehicle to be driven even when a shift position based on the user's shift operation is unrecognized.

In order to achieve the above primary object, the motor vehicle of the present disclosure employs the following configuration.

The present disclosure is directed to a motor vehicle. The motor vehicle includes a driving system configured to cause the motor vehicle to run and a control device configured to recognize a shift position in response to a user's shift operation of a shift lever and to control the driving system, based on the shift position and the user's accelerator operation, brake operation and steering operation. On occurrence of a predetermined abnormality that causes a failure in recognizing the shift position, the control device sets an abnormality-time shift position based on vehicle peripheral information and notifies the abnormality-time shift position, and when a moving direction is set by a moving direction setting unit that is provided separately from the shift lever and that allows the user to set the moving direction, the control device resets the abnormality-time shift position based on the moving direction, and controls the driving system, based on the abnormality-time shift position, the brake operation and the steering operation.

The motor vehicle according to this aspect of the present disclosure recognizes the shift position in response to the user's shift operation of the shift lever and controls the driving system, based on the shift position and the user's accelerator operation, brake operation and steering operation. On occurrence of the predetermined abnormality that causes a failure in recognizing the shift position, the motor vehicle sets the abnormality-time shift position based on the vehicle peripheral information and notifies the abnormality-time shift position. When the moving direction is set by the moving direction setting unit that is provided separately from the shift lever and that allows the user to set the moving direction, the motor vehicle resets the abnormality-time shift position based on the set moving direction, and controls the driving system, based on the abnormality-time shift position, the brake operation and the steering operation. Accordingly, when the predetermined abnormality occurs (i.e., when the shift position is unrecognized), the motor vehicle sets and notifies the abnormality-time shift position, based on the vehicle peripheral information. When the user determines that the abnormality-time shift position is inadequate and sets the moving direction, the abnormality-time shift position is reset, based on the set moving direction. Even when the predetermined abnormality occurs, this configuration enables the motor vehicle to be driven at the user's desired abnormality-time shift position.

“Notification of the abnormality-time shift position” is implemented by display of the abnormality-time shift position on an in-vehicle display or on a display of a mobile terminal or by audio output the abnormality-time shift position from an in-vehicle speaker or a speaker of a mobile terminal. The “moving direction setting unit” may be, for example, an in-vehicle touch panel display, an in-vehicle button, an in-vehicle voice recognition system or a touch panel display, a button or a voice recognition system of a mobile terminal. The mobile terminal may be, for example, a smartphone or a tablet that is communicable with the vehicle and that is taken into the vehicle interior.
