Abstract
The present invention relates to a system and a method for measuring an inclination of a vehicle using an acceleration sensor, which may improve response performance of inclination measurement by adjusting to a driving state of the vehicle. The system includes: a high pass filter configured to high pass filter an output signal of the acceleration sensor that senses a driving acceleration of a vehicle; and a controller configured to deduct the output signal of the acceleration sensor filtered by the high pass filter from an original output signal of the acceleration sensor, calculate a deducted output signal of the acceleration sensor of a predetermined cutoff frequency or lower; and calculate an inclination based on the deducted output signal of the cutoff frequency or lower of the acceleration sensor.
