Steering assist system and vehicle mounted with the same

摘要

The invention relates to a steering assist system and a vehicle mounted with 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. A recommended steering direction determination unit 102 determines a recommended steering direction using measurements of a lateral position taken by an obstacle position measurement unit 101. After a collision determination unit 103 determines 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 105. 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 106, the second assist torque command value being smaller than the first assist torque command value.
