Vehicle Having Retractable Rear Gate

1 . A vehicle comprising:

a vehicle body comprising a rear bumper; and

a rear end module coupled to the rear of the vehicle body, the rear end module comprising:

a rear window, and

a rear gate,

wherein the rear window is configured to move from a closed position to an open position within a cavity of the rear gate, and the rear gate is configured to move from a closed position to an open position within a rear bumper cavity formed by the rear bumper.

2 . The vehicle of claim 1 , wherein the rear end module further comprises:

a rear end frame;

at least one rear gate rail; and

at least one rear gate actuator,

wherein the at least one rear gate actuator is configured to move the rear gate between the closed position and the open position along the rear gate rail.

3 . The vehicle of claim 2 , wherein the rear gate rail is configured such that, when the rear gate is moved from the closed position to open position, the rear gate moves horizontally away from the rear end frame as the rear gate moves vertically down into the rear bumper cavity.

4 . The vehicle of claim 2 , wherein the rear gate actuator comprises:

a motor; and

at least one a cable, belt, chain, or spindle coupled to the motor and the rear gate.

5 . The vehicle of claim 2 , further comprising a control unit configured to control the rear gate actuator to move the rear gate between the closed and open positions.

6 . The vehicle of claim 5 , wherein the control unit is further configured to prevent the rear gate from opening when the rear window is in the closed position.

7 . The vehicle of claim 5 , wherein the control unit is further configured to prevent the rear window from closing when the rear gate is in the open position.

8 . The vehicle of claim 1 , wherein the rear end module further comprises a latch configured to prevent the rear gate from opening or closing.

9 . The vehicle of claim 1 , further comprising: a closure flap configured to cover the rear bumper cavity when the rear gate is in the open position.

10 . A method of manufacturing a vehicle, comprising:

assembling a rear end module on an assembly fixture, the rear end module comprising a rear end frame, rear window, and rear gate, wherein the rear gate is configured to move along the rear end frame from a closed position to an open position; and

affixing the rear end module to a body of the vehicle.

11 . The method of manufacturing a vehicle of claim 10 , wherein assembling the rear end module comprises:

mounting the rear end frame to the assembly fixture;

assembling the rear window within the rear gate; and

mounting the rear gate on to the rear end frame, wherein affixing the rear end module to the body comprises:

positioning the assembly fixture in proximity to the body;

mounting the rear end module on the body; and

removing the assembly fixture from the rear end module.

12 . A method for controlling a vehicle, the method comprising:

receiving a signal to open a rear gate of the vehicle;

in response to the signal:

sending a gate signal to a gate actuator of the rear gate instructing the gate actuator to move the rear gate to a gate-open position within a rear bumper cavity formed by the rear bumper; and

sending a window signal to a window actuator of a rear window instructing the window actuator to move the rear window from a window-closed position to a window-open position within a cavity of the rear gate.

13 . The method of claim 12 , comprising:

receiving a second signal to close the rear gate; and

in response to the second signal, sending a second gate signal to the gate actuator instructing the gate actuator to move the rear gate to a closed position.

14 . The method of claim 13 , comprising:

sending a second window signal to the window actuator instructing the window actuator to move to the window-closed position.

15 . The method of claim 12 , comprising:

sending a flap signal to a closure actuator instructing the closure actuator to close a flap over an opening of the rear bumper cavity when the rear gate is in the rear bumper cavity.

16 . The method of claim 12 , comprising:

before sending the gate signal, sending a signal to a latch actuator instructing the latch actuator to release a latch holding the rear gate in the gate-open position.

17 . The method of claim 12 , wherein the gate actuator moves the rear gate simultaneously with the window actuator moving the rear window.

18 . The method of claim 12 , wherein the gate actuator moves the rear gate in response to the rear window reaching the window-open position.

19 . The method of claim 12 , wherein the signal is received from a button or a motion sensor.

20 . The method of claim 12 , wherein the signal is received over a wireless link.
