20150192947 | STEERING APPARTUS FOR A STEERED VEHICLE - A steering apparatus comprises a rotatable steering shaft and a sensor which senses angular movement of the steering shaft. An electromagnetic actuator actuates a stop mechanism to releasable engage the steering shaft. There is a microcontroller which causes the electromagnetic actuator to actuate the stop mechanism to fully engage the steering shaft and prevent rotation of the steering shaft in a first rotational direction, which corresponds to movement towards the hardstop position, while allowing rotational play between the steering shaft and the stop mechanism in a second direction, which corresponds to rotational movement away from the hardstop position, when the sensor senses that the steering shaft has reached a hardstop position. A driver applies a reserve polarity pulse to the electromagnetic actuator when the stop mechanism is fully engaged and the steering shaft is rotated, as permitted by the rotational play, in the second rotational direction. | 07-09-2015 |
