Ramp assembly with tilt sensor |
摘要 |
A ramp assembly provides a transition surface from a vehicle interior to an alighting surface. The ramp assembly includes a ramp portion that rotates between a stowed position and a deployed position. The ramp portion is rotatable about an axis associated with a first end of the ramp portion. A support member supports the first end of the ramp portion, and a sensor is configured to sense a predetermined position of the ramp portion. The ramp assembly further includes an actuator operably coupled to the ramp portion to drive the ramp portion through a first phase and a second phase of a deployment motion. During the first phase, the actuator rotates the ramp portion about the axis while the axis maintains a substantially fixed position. During the second phase, the actuator moves the axis in a downward direction if the ramp portion has deployed to at least the predetermined position. |
