ABSTRACT:
A tilt angle detecting apparatus removes an unnecessary component included in an angular velocity detecting signal (an input ω) inputted from an angular velocity sensor1with the deadband (−ωo to +ωo) of an unnecessary component removing means2, performs integration processing on the angular velocity detecting signal (an output ω) which is allowed to pass through the passband (input ω>ωo or input ω<−ωo) of the unnecessary component removing means2and which is outputted from the unnecessary component removing means by using an arithmetic processing means3, performs a process of resetting the integral value to zero using a fixed integral value resetting value which is determined in such a way as to be suited to the above-mentioned deadband by using an integral value resetting means4after the integration processing, and outputs a signal showing the roll angle θv of a vehicle.
