| A vehicle operation assist system includes an assist yaw rate calculator which calculates a necessary moving amount to avoid an obstacle based on a detection result of the obstacle by a radar device, and a vehicle movement controller controls lateral movement of the vehicle based on the calculated moving amount. When an avoiding operation detector determines initiation of an obstacle avoiding operation by the driver, the vehicle movement controller operates a braking device to control the lateral movement of the vehicle, so that the obstacle can be reliably avoided. When a restoring operation detector determines initiation of a restoring operation, the vehicle movement controller operates a power steering device to control the lateral movement of the vehicle, so that delay in the steering operation by the driver, and excessive restoring operation of the steering handle to compensate for the delay are suppressed, thus stabilizing vehicle behavior. A vehicle operation assisting system capable of properly assisting in both an obstacle avoiding operation and a restoring operation by a driver is thereby provided. | ||||||

| System for detecting stability/instability of behavior of a motor vehicle upon occurrence of tire slip or lock. State of the motor vehicle is determined on the basis of an alignment torque (Ta) applied from a road and a side slip angle (β). By taking advantage of such torque/slip-angle characteristic that although the alignment torque is proportional to a side slip angle when the latter is small, the alignment torque becomes smaller as the side slip angle increases, a normal value is determined from a straight line slope and the side slip angle in a region where the latter is small. Unstable behavior of the motor vehicle is determined when deviation of actual measured value from the normal value increases. Further, unstable state is determined when the slope of the alignment torque for the slip angle departs significantly from that of approximate straight line slope. | ||||||

| A target resultant force to be applied to a vehicle body is calculated, the magnitude of a critical friction circle of each wheel is estimated, and a critical resultant force is estimated from the estimated magnitude of the critical friction circle. Subsequently, a ratio of the target resultant force to a critical resultant force is set as an effective road friction, and the magnitude of a tire force is set by using the magnitude of the critical friction circle and the effective road friction. The direction of the tire force of each wheel to be controlled is set based on the sum of products, which are calculated for all other wheels, of a distance from the position of the wheel to be controlled to the position of the other wheel in a direction of the resultant force, and the magnitude of the tire force of the other wheel. Cooperative control of steering and braking or steering and driving of each wheel to be controlled is performed based on the magnitude and direction of the tire force which have been set. | ||||||
