Patent ID: 7260459

Claim:
A turning motion control system for a vehicle, comprising: a target turning motion state determining means for determining a target turning motion state of the vehicle; a turning motion state detecting means for detecting an actual turning motion of the vehicle; an actuator control means for controlling an actuator so that the actual turning motion state of the vehicle detected by the turning motion state detecting means becomes close to the target turning motion state determined by the target turning motion state determining means; and a switching means adapted to switch over a control-permitted state and a control-stopped state of the actuator upon operation by a driver, wherein the system further comprises an air-pressure decreased state detecting means capable of detecting an air-pressure decreased state of any of wheels, and wherein the actuator control means is adapted to carry out the control of the operation of the actuator, irrespective of the switching mode of the switching means, when the air-pressure decreased state detecting means has detected the air-pressure decreased state.
