車両の操舵装置
Document Type and Number:
Japanese Patent JP4280682
Kind Code:
B2
Abstract:
An object of the present invention is to correctly generate a motion state quantity anticipated by a driver with respect to an operation of a steering handle by a driver, thereby facilitating driving a vehicle. In a vehicle steering apparatus, front wheels are controlled to be turned by a computer program processing. A displacement/torque conversion section 51 converts a steering angle ¸ into a steering torque Td that is in relation of exponential function. A torque/lateral-acceleration conversion section 52 converts into an anticipated lateral acceleration Gd based upon the steering torque Td. A turning angle conversion section 55 calculates target turning angles ´d. A turning angle correcting section 61 obtains a slip angle ² of a slip generated on a vehicle. Then, the turning angle correcting section 61 corrects the target turning angle ´d based upon the obtained slip angle ², thereby calculating a corrected target turning angle ´da. A drive control section 63 controls the steered wheels to be turned into the corrected target turning angle ´da. According to this, a driver can correctly perceive the generated anticipated lateral acceleration Gd, whereby he/she can easily drive the vehicle.
