Turning control apparatus for vehicle
First Claim
1. A turning control apparatus for a vehicle comprising:
- a driving torque controller for adjusting driving torque between a left wheel and a right wheel;
means for detecting turning direction of the vehicle;
means for determining which of the left wheel and the right wheel is an inside-wheel or an outside-wheel according to the turning direction detected by said turning direction detecting means;
means for sensing rotation speed of an inside-wheel which is opposite to the outside-wheel;
means for sensing rotation speed of the outside-wheel;
means for calculating a necessary yaw momentum value indicating degree of necessary yaw momentum for the turning of the vehicle; and
means for clipping the necessary yaw momentum value as a target yaw momentum at a maximum yaw momentum value, which is defined according to difference between the inside-wheel rotation speed sensed by said inside-wheel rotation speed sensing means and the outside-wheel rotation speed sensed by said outside-wheel rotation speed sensing means, if the necessary yaw momentum value is over the maximum yaw momentum value;
said driving torque controller adjusting between driving torque of the left wheel and the right wheel so as to generate target yaw momentum at the vehicle corresponding to the target yaw momentum value obtained by said necessary yaw momentum value clipping means.

Abstract
The present invention provides a turning control apparatus for a vehicle to improve turning ability and to avoid degradation of acceleration ability.
The turning control apparatus comprises: a driving torque controller (31) for adjusting driving torque between a left and right wheels (14L and 14R); means (62) for calculating a necessary yaw momentum value indicating degree of necessary yaw momentum for the turning of the vehicle; and means (63) for clipping the necessary yaw momentum value as a target yaw momentum at a maximum yaw momentum value, which is defined according to difference between the inside-wheel rotation speed and the outside-wheel rotation speed (−), if the necessary yaw momentum value is over the maximum yaw momentum value.
The driving torque controller (31) adjusts between driving torque of the left and right wheels (14L and 14R) so as to generate target yaw momentum at the vehicle corresponding to the target yaw momentum value obtained by the necessary yaw momentum value clipping means (63).
