Abstract
The present invention relates to a device for detecting the center of a steering angle in a vehicle. This device comprises a steering angle sensor provided on a vehicle steering mechanism for electrically detecting a steering angle, a temporary storing portion for temporarily storing a center value calculated in response to an output from the sensor through a first switch, a comparison circuit for comparing the center value stored in the temporary storage portion with an output from the steering angle sensor to ON-OFF operate the first switch, a center storage portion for taking out the center value in the temporary storage portion through a second switch to store the same, and a distance measuring portion controlled by the comparison circuit, for ON-OFF operating the second switch after a lapse of a predetermined running distance upon ON-operation of the first switch, the aforesaid center storage portion including an integration circuit having a resistor and a capacitor. The device can reliably, electrically take out only the substantially effective change in the steering angle in a vehicle, so that various vehicle controls can be effectively performed.
