Abstract
In a vehicle steering apparatus, front wheels are controlled to be turned by a computer program processing. A displacement/torque conversion sectionconverts a steering angle θ into a steering torque Td that is in relation of exponential function. A torque/lateral-acceleration conversion sectionconverts into an anticipated lateral acceleration Gd based upon the steering torque Td. A turning angle conversion sectioncalculates target turning angles δd. A turning angle correcting sectionobtains a slip angle β of a slip generated on a vehicle. Then, the turning angle correcting sectioncorrects the target turning angle δd based upon the obtained slip angle β, thereby calculating a corrected target turning angle δda. A drive control sectioncontrols the steered wheels to be turned into the corrected target turning angle δda. According to this, a driver can correctly perceive the generated anticipated lateral acceleration Gd, whereby he/she can easily drive the vehicle.
