Vehicle running control device
First Claim
1. A device for controlling a running condition of a vehicle having a vehicle body and a first apparatus of generating a yaw moment thereon;
- the device comprising a portion of judging a running condition of the vehicle and a portion of executing a running stability control of the vehicle through generating a stabilizing yaw moment to the vehicle by operating the first yaw moment generating apparatus;
wherein the vehicle has a second apparatus of generating a yaw moment on the vehicle body and a detector of detecting an actual yaw rate of the vehicle; and
the device further comprises a portion of calculating a target yaw rate for the vehicle based upon a driver'"'"'s operation and a portion of calculating an integration value of yaw rate deviations between the actual and target yaw rates; and
a portion executing a control of correcting a yaw direction of the vehicle body based upon the integration value of the yaw rates through generating a direction correcting yaw moment by operating the second yaw moment generating apparatus.

Abstract
There is provided a new and novel vehicle running control device for correcting a yaw angle of a vehicle toward the yaw direction intended by a driver, together with vehicle stability control, through generating yaw moments. In order to accomplish the yaw angle correction, the inventive device operates a yaw moment generating apparatus e.g. a steering apparatus, so as to generate a direction correcting yaw moment based upon an integration value of the deviations between an actual yaw rate and its target value. The direction correcting yaw moment may be generated for correcting the yaw angle deviation remaining after the stability control is ended.
