Abstract

A vehicle includes a vehicle body having a pillar, a vehicle door movably coupled to the vehicle body, and an assembly for at least partially opening the vehicle door. The assembly is coupled to the vehicle door and includes an actuator having an actuator body and an actuator shaft movable relative to the actuator body between a retracted position and an extended position. Further, the assembly includes a lever pivotally coupled to the vehicle door and a spring coupled between the lever and the actuator shaft. The spring biases the lever toward the pillar. When the vehicle door is unlatched, the lever exerts a force on the pillar and, consequently, pushes the vehicle door away from the pillar to a partially open position. The present disclosure also relates to the assembly for at least partially opening the vehicle door as described above.

Claims

1. A vehicle, comprising:

a vehicle body including a pillar;

a vehicle door movably coupled to the vehicle body;

an assembly coupled to the vehicle door for at least partially opening the vehicle door, wherein the assembly includes;

an actuator including an actuator body and an actuator shaft movable relative to the actuator body between a retracted position and an extended position;

a lever pivotally coupled to the vehicle door; and

a spring coupled between the lever and the actuator shaft such that the spring biases the lever toward the pillar.

2. The vehicle of claim 1, further comprising a control module in communication with the actuator, wherein the control module is specifically programmed to command the actuator to move the actuator shaft relative to the actuator body between the retracted position and the extended position.

3. The vehicle of claim 2, further comprising a door latch coupled to the vehicle door and a striker coupled to the vehicle body, wherein the door latch is selectively coupled to the striker to lock the vehicle door to the vehicle body.

4. The vehicle of claim 3, further comprising a door sensor in communication with the control module and the door latch, wherein the door sensor is configured to detect whether the door latch is latched to the striker or unlatched from the striker.

5. The vehicle of claim 4, wherein the control module is programmed to command the actuator to maintain the actuator shaft in the extended position such that the spring biases the lever toward the pillar in order to maintain the lever pressed against the pillar while the vehicle door is in a closed position.

6. The vehicle of claim 5, wherein the control module is programmed to command the door latch to unlatch from the striker upon receipt of an unlatch signal, thereby allowing the lever to rotate in order to push the vehicle door away from the pillar to a partially open position.

7. The vehicle of claim 6, wherein the control module is programmed to command the actuator to move the actuator shaft from the extended position to the retracted position upon receipt of an input signal from the door sensor indicating that the vehicle door is in a fully unlatched position.

8. The vehicle of claim 7, wherein the control module is programmed to command the actuator to move the actuator shaft from the retracted position to the extended position after the control module receives an input signal from the door sensor indicating that the vehicle door is in the closed position relative to the vehicle body.

9. The vehicle of claim 4, wherein the control module is programmed to command the actuator to maintain the actuator shaft in the retracted position while the vehicle door is in the closed position in order to maintain the lever spaced apart from the pillar while the vehicle door is in the closed position relative to the vehicle body.

10. The vehicle of claim 9, wherein the control module is programmed to command the actuator to move the actuator shaft from the retracted position to the extended position upon receipt of an input signal from the door sensor indicating that the door latch is unlatched from the striker, thereby allowing the lever to exert a force against the pillar in order to move the vehicle door to a partially open position.

11. The vehicle of claim 10, wherein the control module is programmed to command the actuator to move the actuator shaft from the extended position to the refracted position upon receipt of an input signal from the door sensor indicating that the vehicle door is in a fully unlatched position.

12. The vehicle of claim 9, wherein the control module is programmed to command the actuator to move the actuator shaft from the retracted position to the extended position upon receipt of an input signal from the control module to unlatch simultaneously while the door latch is unlatching from the striker.

13. The vehicle of claim 9, wherein the control module is programmed to command the door latch to unlatch from the striker and to move the actuator shaft from the retracted position to the extended position, wherein the unlatching of the door latch and moving the actuator shaft to the extended position do not occur simultaneously.

14. The vehicle of claim 13, wherein the control module is programmed to command the actuator to move the actuator shaft from the extended position to the retracted position after a predetermined amount of time has passed since the control module received the input signal from the door sensor indicating that the vehicle door is unlatched.

15. The vehicle of claim 3, wherein the lever is pivotally coupled to the vehicle door such that the lever directly contacts the pillar in order to exert a force on the pillar when the door latch unlatches from the striker.

16. The vehicle of claim 2, further comprising a check link assembly coupled between the vehicle body and the vehicle door, wherein the lever is configured to contact the check link assembly such that the lever is configured to exert a force on the check link assembly in order to move the vehicle door to a partially open position.

17. The vehicle of claim 16, wherein the check link assembly includes a housing and a link movably coupled to the housing, and the lever is in direct contact with the link.

18. The vehicle of claim 17, further comprising a yoke interconnecting the lever and the link when the vehicle door is in the closed position.

19. A assembly for opening a vehicle door relative to a pillar of a vehicle body, the assembly comprising:

an actuator including an actuator body and an actuator shaft movable relative to the actuator body between a retracted position and an extended position;

a lever pivotally couplable between the vehicle door and the vehicle body; and

a spring coupled between the lever and the actuator shaft such that the spring biases the lever toward the pillar.

20. The assembly of claim 19, further comprising a frame and a pivot pin pivotally coupling the lever to the frame, wherein the pivot pin defines an axis of rotation, and the spring is a torsion spring and is configured to urge the lever to rotate about the axis of rotation defined by the pivot pin.
