Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 角速度センサのドリフトによってサスペンシ ョンや四輪操舵装置の制御が不安定になるのを防ぐ。 【構成】 車速センサ1で車速を検出し、ヨ−角速度セ ンサ2で車両のヨ−軸回りの角速度を検出する。ドリフ ト推定手段6ではヨー角速度センサ2の出力信号からド リフト量および零点を算出し、これを基に角速度補正手 段7でヨー角速度センサ2の出力信号を補正する。旋回 状態推定手段8では、車速センサ1からの出力信号とヨ ー角速度の補正値とによって旋回時に発生するローリン グの程度を推定し、これを抑制するように制御信号を出 力する。旋回状態推定手段8からの制御信号によって駆 動回路9はアクチュエータ4を駆動し、ショックアブソ ーバ3の減衰力を制御をする。 (57) [Abstract] [Purpose] It prevents the control of the suspension and four-wheel steering system from becoming unstable due to the drift of the angular velocity sensor. [Construction] A vehicle speed sensor 1 detects a vehicle speed, and a yaw angular velocity sensor 2 detects an angular velocity around a yaw axis of the vehicle. The drift estimation unit 6 calculates the drift amount and the zero point from the output signal of the yaw angular velocity sensor 2, and the angular velocity correction unit 7 corrects the output signal of the yaw angular velocity sensor 2 based on this. The turning state estimation means 8 estimates the degree of rolling that occurs during turning based on the output signal from the vehicle speed sensor 1 and the yaw angular velocity correction value, and outputs a control signal to suppress this. The drive circuit 9 drives the actuator 4 by the control signal from the turning state estimating means 8 to control the damping force of the shock absorber 3.
