Title:
Method for correcting the vehicle G sensor output value and for detecting G sensor failure
Abstract:
A method for correction of the G sensor output of a vehicle. The method is for a vehicle equipped with a G sensor, a wheel speed sensor to detect the rotational speed of a wheel of the vehicle, and an electronic control device conducting computations from the signals received from the G sensor and the wheel speed sensor. The method includes steps of determining the acceleration/deceleration at every predetermined time and the G sensor output value, determining the G sensor zero point from the G sensor output value, and determining the current G sensor zero point based on the G sensor zero point which is determined before the predetermined time.
