Various vehicle systems are proposed for accessing and utilizing vehicle cargo spaces on vehicles equipped with a tailgate assembly. The vehicle systems may include deployable and/or rotatable stairgate systems, deployable step systems, etc. designed for the accessing the vehicle cargo spaces. The proposed systems may include various deployment mechanisms that enable the stairgate/step systems to slide, pivot, rotate, swing, and/or otherwise adjust for providing ease of access and increased flexibility when stepping up to access the vehicle cargo space.

Embodiments of a system for controlling a vehicle power tailgate are described. The system includes a motor operably connectible to a tailgate to open and close the tailgate, a processor, and a memory communicably coupled to the processor. The memory stores a tailgate control module including instructions that when executed by the processor cause the processor to, responsive to a value of a motor speed parameter being above a predetermined motor speed threshold and a value of a motor acceleration parameter being above a predetermined motor acceleration threshold during opening of a tailgate, control operation of the motor to apply a braking force to the tailgate.

A method of operating a tonneau cover and a tailgate of a vehicle, including: transmitting one or more signals to a first control module to open or lower the tailgate; determining a position of the tonneau cover with the first control module or a second control module and transmitting by the first control module and/or the second control module one or more signals to a mechanism associated with the tonneau cover to open the tonneau cover if the tonneau cover is determined by the first control module and/or the second control module to be in a closed position; and then lowering the tailgate.

Vehicle tailgate assembly that includes a sill flap and tailgate, where the sill flap has rollers that contact the tailgate while the sill flap and tailgate are opened or closed. The sill flap thus maintains rolling contact with the tailgate during opening and closing operations. In embodiments of the disclosure, the tailgate opens to leave a gap between the edge of the vehicle bed and the edge of the tailgate, and the sill flap is pivoted into this gap. While being pivoted into this open position, the sill flap rollers rotatably contact the tailgate, so that the sill flap maintains rolling contact with the tailgate rather than frictional contact therewith. This prevents damage to the sill flap and tailgate when opened and closed.

A stake post having a locking hinge that enables selective movement of a gate unit between a first position in which the gate unit forms a portion of a retaining wall in cooperation with other gate units, and a second position in which the gate unit is removed from alignment with one or more adjacent gate units to thereby provide an opening through a retaining wall otherwise formed by the stake post when in the first position.

A sensor module for a vehicle includes a housing structured to be mounted along a sidewall of a cargo door, and a pressure-sensitive sensor mounted in the housing so as to be extendible from the housing and retractable into the housing. A sensor deployment mechanism is operatively coupled to the sensor and is structured to be operable to extend the sensor from the housing and to retract the sensor into the housing.
