Patent number: 8788149Abstract: A CPU changes a turning angle corresponding to a steering angle required for a steering device to steer a host vehicle, depending on the amount of operation for moving a steering wheel at a reference position in a tilt direction and a push-pull direction. A tilt reaction force device and a push-pull reaction force device generate a reaction force against a second operation amount for moving the steering wheel from the reference position according to the reference position of the steering wheel relative to the driver which is adjusted by a tilt/expansion mechanism. In this way, even when the reference position of the steering wheel is changed, it is possible to give an appropriate reaction force to the driver since a reaction force against, for example, an operation of pushing or pulling the steering wheel is generated according to the reference position of the steering wheel relative to the driver.Type: GrantFiled: August 5, 2010Date of Patent: July 22, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yukihide Kimura, Ryota Osumi
