  • Ramp assembly with tilt sensor
    Patent number: 8869333
    Abstract: A ramp assembly for providing a transition surface between a vehicle floor and an alighting surface is disclosed. The ramp assembly includes a ramp portion that is rotatable between a stowed position and a deployed position. A sensor senses an angle of the ramp portion relative to a horizontal plane and provides a sensor output that corresponds to the angle of the ramp portion relative to the horizontal plane. The ramp assembly further includes a controller that receives the sensor output and an alert device. The controller controls the alert device to provide an alert when the angle of the ramp portion relative to the horizontal plane reaches a predetermined value.
