<p>PROBLEM TO BE SOLVED: To induce a user to pay attention to grip a steering wheel 18 if the user separates user's hands from the steering wheel 18 for a vehicle 10 steered according to a user's operation of the steering wheel 18.SOLUTION: If a tactile sensor 42 detects user's separation of hands from a steering wheel 18 while a vehicle 10 is traveling on a narrow road, a controller 30 outputs an appropriate steering angle (recommended steering angleθ*) for preventing the vehicle 10 from colliding against an obstacle to a steering control unit 16. By doing so, a steering wheel steering angleθc that is the steering angle of the steering wheel 18 in addition to a steering wheel steering angleθthat is an actual steering angle is recognized as the recommended steering angleθ*. However, a user is caused to pay attention to grip the steering wheel 18 by reducing a command torque Trq* to a main machine unit 20 before the vehicle 10 arrives at a terminal end of the narrow road.</p> |
