Abstract
An object of the present invention is to provide a steering assist system capable of showing a driver an appropriate direction of steering operation in advance and correctly, and without impairing safety, and shortening an operation time during collision avoidance, in particular, reducing an idle running time. It is another object of the present invention to provide a vehicle mounted with such a steering assist system. A recommended steering direction determination unitdetermines a recommended steering direction using measurements of a lateral position taken by an obstacle position measurement unit. After a collision determination unitdetermines that risk of collision is high, a steering assist torque is generated using a first assist torque command value set by a first torque calculation unit. After a predetermined period of time after the driver starts steering or the steering assist torque using the first assist torque command value is generated, a steering assist torque is generated using a second assist torque command value set by a second torque calculation unit, the second assist torque command value being smaller than the first assist torque command value.
