Title:
CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JPH0648141
Kind Code:
A
Abstract:
PURPOSE: To reduce the number of sensors used in the case of performing various control on a vehicle so as to attain the cost reduction of a device and the rationalization of sensor fitting space.
CONSTITUTION: The output signal (acceleration signal) of an acceleration sensor 17 is divided into two signals, and one signal V1 is inputted into a control circuit 20 through a first LPF(low-pass filter) 13a and an A/D 26. The other output signal V2 is inputted into the control circuit 20 through an LPF 13b and an A/D 23. The control circuit 20 performs specified arithmetic processing and performs active suspension control on the basis of the signal V1 and active noise eliminating control on the basis of the signal V2.
