First Claim
Patent Images
1. A power drift control device for a vehicle comprising:
- cornering detecting means for detecting cornering of the vehicle and producing a signal representative of same;
acceleration detecting means for detecting acceleration of the vehicle and producing a signal representative of same;
yaw moment producing means responsive to said signals from said cornering detecting means and said acceleration detecting means for producing a yaw moment in the direction of causing oversteer and variable at a yaw moment variation rate depending upon variation of acceleration of the vehicle;
steering wheel angle detecting means for detecting a steering wheel angle and producing a signal representative of same; and
yaw moment variation rate altering means responsive to said signal from said steering wheel angle detecting means for altering said yaw moment variation rate in such a manner that said yaw moment variation rate increases as said steering wheel angle increases.

Abstract
A power drift control device produces a yaw moment in the direction of causing oversteer on the basis of acceleration and steering wheel angle during cornering of a vehicle. The yaw moment is variable depending upon variation of acceleration at a rate which increases as a steering wheel angle increases.
