Abstract

A vehicle controller which can perform appropriate control even when an acceleration sensor is mounted in a movable portion of a vehicle. The vehicle controller includes an acceleration sensor attached to a cabin movable around a shaft, an open/closed state detection section which detects the open/closed state of the cabin, and a correction section which corrects the output value of the acceleration sensor. When the open/closed state detection section detects that the cabin is opened and then closed, the correction section performs correction. When the acceleration sensor is provided in the cabin serving as a movable portion, the inclination of the acceleration sensor may differ slightly before and after the cabin is opened.

Claims

1. A vehicle, comprising:

a cabin movable around a shaft;

a vehicle controller, the vehicle controller, further comprising;

a vehicle motion state quantity sensor which is attached to the cabin; and

an electronic control unit, the electronic control unit, further comprising;

an open/closed state detection unit which detects the open/closed state of the cabin;

a correction unit programmed to correct the output value of the vehicle motion state quantity sensor, and

an operating unit programmed to perform an operation on the basis of the output value of the vehicle motion state quantity sensor,

wherein, when the open/closed state detection unit detects that the cabin is opened and then closed, the correction unit performs correction, and

wherein, when the open/closed state detection unit detects that the cabin is open while the vehicle is stopped, the operating unit is programmed to hold an operational sensor output value before the cabin is opened as the operational sensor output value of the vehicle motion state quantity sensor.

2. A vehicle, comprising:

a cabin movable around a shaft;

a vehicle controller, the vehicle controller, further comprising;

a vehicle motion state quantity sensor which is attached to the cabin; and

an electronic control unit, the electronic control unit, further comprising;

an open/closed state detection unit which detects the open/closed state of the cabin;

an abnormality detection unit programmed to detect abnormality in the vehicle motion state quantity sensor, and

an operating unit programmed to perform an operation on the basis of the output value of the vehicle motion state quantity sensor,

wherein, when the open/closed state detection unit detects that the cabin is open, abnormality detection of the abnormality detection unit is inhibited, and

wherein, when the open/closed state detection unit detects that the cabin is open while the vehicle is stopped, the operating unit is programmed to hold an operational sensor output value before the cabin is opened as the operational sensor output value of the vehicle motion state quantity sensor.

3. A vehicle, comprising:

a cabin movable around a shaft;

a vehicle controller, the vehicle controller, further comprising;

a vehicle motion state quantity sensor which is attached to the cabin; and

an electronic control unit, the electronic control unit, further comprising;

an open/closed state detection unit which detects the open/closed state of the cabin; and

an operating unit programmed to perform an operation on the basis of the output value of the vehicle motion state quantity sensor,

wherein, when the open/closed state detection unit detects that the cabin is open while the vehicle is stopped, the operating unit is programmed to hold an operational sensor output value before the cabin is opened as the operational sensor output value of the vehicle motion state quantity sensor.
