First Claim
Patent Images
1. An offset correcting apparatus of a yaw rate sensor, comprising:
- a current status determining unit which determines a status of its own vehicle as one of a driving vehicle and a stopped vehicle;
a first offset correcting unit which if its own vehicle is determined as the driving vehicle, when its own vehicle is being driven in a straight line, corrects an offset of a yaw rate sensor which is installed in its own vehicle; and
a second offset correcting unit which if its own vehicle is determined as the stopped vehicle, when a position of its own vehicle is not changed, corrects the offset of the yaw rate sensor.

10. An offset correcting method of a yaw rate sensor, comprising:
-
determining a status of its own vehicle as one of a driving vehicle and a stopped vehicle; and if its own vehicle is determined as the driving vehicle, correcting an offset of a yaw rate sensor which is installed in its own vehicle when its own vehicle is being driven in a straight line and if its own vehicle is determined as the stopped vehicle, correcting the offset of the yaw rate sensor when a position of its own vehicle is not changed. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A vehicle speed control system, comprising:
-
an offset correcting apparatus which includes; a current status determining unit which determines a status of its own vehicle as one of a driving vehicle and a stopped vehicle; a first offset correcting unit which if its own vehicle is determined as the driving vehicle, when its own vehicle is being driven in a straight line, corrects an offset of a yaw rate sensor which is installed in its own vehicle; and a second offset correcting unit which if its own vehicle is determined as the stopped vehicle, when a position of its own vehicle is not changed, corrects the offset of the yaw rate sensor; a curvature radius estimating device which estimates a radius of curvature of its own vehicle based on the offset of the yaw rate sensor; and a vehicle speed control device which controls a speed of its own vehicle based on sensing information obtained from sensors which are installed in its own vehicle and the radius of curvature of its own vehicle. - View Dependent Claims (20)
