Inclination angle detecting device for a vehicle and by means of impact assessment in front of the direction of the inclination angle detecting device for a vehicle

摘要

A tilt angle detecting apparatus removes an unnecessary component included in an angular velocity detecting signal (an input ω) inputted from an angular velocity sensor 1 with the deadband (−ωo to +ωo) of an unnecessary component removing means 2, performs integration processing on the angular velocity detecting signal (an output ω) which is allowed to pass through the passband (input ωωo or input ω−ωo) of the unnecessary component removing means 2 and which is outputted from the unnecessary component removing means by using an arithmetic processing means 3, 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 means 4 after the integration processing, and outputs a signal showing the roll angle &thetas;v of a vehicle.
