VEHICLE INCLINATION ANGLE DETECTOR, POWER SOURCE CONTROL APPARATUS HAVING THE VEHICLE INCLINATION ANGLE DETECTOR AND VEHICLE COMPRISING THE SAME

摘要

A vehicle inclination angle detector is configured to suppress the difference between an actual vehicle inclination angle and a calculated vehicle inclination angle to allow for stable detection of the same. The detector includes a vertical acceleration sensor, a lateral acceleration sensor, an inclination angle calculating module and a calculation cancelling module. A detection direction of the vertical acceleration sensor with respect to the vehicle is determined such that its acceleration in the gravity direction is detected when the vehicle is in a non-inclined state. Acceleration in the lateral direction is detected when the vehicle is in the non-inclined state. The inclination angle calculating module calculates an inclination angle of the vehicle in the lateral direction based on the detected vertical acceleration and the lateral acceleration. The calculation cancelling module cancels the inclination angle calculation when the detected vertical acceleration and the lateral acceleration satisfy a predetermined error detection condition.
