Tailgate interlocking occupant step
A tailgate interlocking occupant step apparatus and method for a vehicle, includes a powered tailgate, a powered occupant step, a kick sensor mounted to the occupant step, and a controller having processing circuitry. The processing circuitry detects a signal from the kick sensor, operates the powered occupant step to move the occupant step to an extended position, operates the powered tailgate to lower the tailgate to an opened position, and when a pinch force is detected either in the occupant step or the tailgate, stops the operation of both the occupant step and the tailgate.
1. A tailgate interlocking occupant step apparatus for a vehicle, comprising:
a powered tailgate;
a powered occupant step;
a kick sensor mounted to the occupant step; and
a controller having processing circuitry configured to:
detect a signal from the kick sensor,
operate the powered occupant step to move the occupant step to an extended position,
operate the powered tailgate to lower the tailgate to an opened position, and
when a pinch force is detected either in the occupant step or the tailgate, stop the operation of at least one of the occupant step and the tailgate or operate at least one of the occupant step and the tailgate in reverse.
2. The apparatus of claim 1 , wherein the processing circuitry is common processing circuitry for operating both the powered occupant step and the powered tailgate.
3. The apparatus of claim 1 , wherein the kick sensor is a capacitive sensor that detects an approaching object by a change in capacitance to a predetermined capacitance threshold.
4. The apparatus of claim 2 , wherein when the signal from the kick sensor is detected, the common processing circuitry operates the occupant step and the tailgate substantially simultaneously.
5. The apparatus of claim 2 , wherein when the pinch force is detected in the occupant step, the common processing circuitry operates the tailgate to move in reverse.
6. The apparatus of claim 1 , further comprising at least one of a warning buzzer and a hazard lamp,
wherein when the pinch is detected, the processing circuitry activates at least one of the warning buzzer and the hazard lamp.
7. The apparatus of claim 2 , wherein when the pinch force is detected in the occupant step, the common processing circuitry operates both the tailgate and the occupant step in reverse substantially simultaneously.
8. The apparatus of claim 1 , wherein the powered occupant step includes a spindle attached to a respective occupant step motor.
9. The apparatus of claim 8 , wherein the pinch force is detected when the motor for the occupant step receives a force in the opposite direction of operation movement that causes a decrease in motor speed or an increase in load that is greater than a predetermined threshold.
10. The apparatus of claim 1 , wherein the controller is configured to set a setting that prevents the powered occupant step from being operated.
11. The apparatus of claim 1 , wherein the controller is configured to set a setting that prevents both the powered occupant step and the powered tailgate from operating.
12. The apparatus of claim 2 , further comprising a tailgate handle,
wherein the common processing circuitry of the controller is further configured to:
detect a signal indicating operation of the tailgate handle,
operate the powered occupant step to move the occupant step to an extended position,
operate the powered tailgate to lower the tailgate to an opened position, and
when a pinch force is detected either in the occupant step or the tailgate, stop operation of at least one of the occupant step and the tailgate or operate at least one of the occupant step and the tailgate in reverse.
13. A method for a tailgate interlocking occupant step of a vehicle including a powered tailgate, a powered occupant step, a kick sensor mounted to the occupant step, and a controller having common processing circuitry for operating both the powered tailgate and the powered occupant step, the method comprising:
detecting, by the common processing circuitry, a signal from the kick sensor,
operating, by the common processing circuitry, the powered occupant step to move to an extended position,
operating, by the common processing circuitry, the powered tailgate to lower to an opened position, and
when a pinch force is detected either in the occupant step or the tailgate, stopping, by the common processing circuitry, the operation of at least one of the occupant step and the tailgate or operate at least one of the occupant step and the tailgate in reverse.
14. The method of claim 13 , wherein when the signal from the kick sensor is detected, operating, by the common processing circuitry, the occupant step and tailgate substantially simultaneously.
15. The method of claim 13 , wherein when the pinch force is detected in the occupant step, operating, by the common processing circuitry, the tailgate to move in reverse.
16. The method of claim 13 , wherein when the pinch force is detected, activating, by the processing circuitry, a warning buzzer and a hazard lamp.
17. The method of claim 13 , wherein when the pinch force is detected in the occupant step, operating, by the common processing circuitry, both the tailgate and the occupant step in reverse substantially simultaneously.
18. The method of claim 13 , the vehicle further comprising a tailgate handle,
the method further comprising:
detecting, by the common processing circuitry, a signal indicating operation of the tailgate handle,
operating, by the common processing circuitry, the powered occupant step to move to an extended position,
operating, by the common processing circuitry, the powered tailgate to lower to an opened position, and
when a pinch force is detected either in the occupant step or the tailgate, stopping, by the common processing circuitry, operation of at least one of the occupant step and the tailgate or operate at least one of the occupant step and the tailgate in reverse.
