Abstract

A vehicle steering apparatus includes a steering wheel, a steering angle sensor, a turning drive mechanism for changing the direction of front wheels, and an ECU for driving the turning drive mechanism in correspondence with a steering signal. The ECU has a phase advance factor part for adding a phase advance component to the steering signal and a subtracting part for applying a behavior quantity signal outputted from a vehicle behavior sensor as a feedback signal to the output signal of the phase advance factor part.

Claims

1. A vehicle steering apparatus, comprising:

an operating device steer-operated by a driver;

operation state level detecting means for detecting an operation state level of the operating device;

a turning actuator for changing the direction of steered wheels;

control means for driving the turning actuator in correspondence with a steering signal pertaining to the operation state level outputted from the operation state level detecting means;

phase component adjusting means for applying a phase advance component to the steering signal outputted by the operation state level detecting means;

behavior quantity detecting means for detecting a behavior quantity of the vehicle; and

signal applying means for applying a behavior quantity signal outputted by the behavior quantity detecting means to an output signal of the phase component adjusting means as a feedback signal.

2. A vehicle steering apparatus according to claim 1, wherein said behavior quantity of the vehicle is a yaw rate or a sideways acceleration.
