Abstract

A vehicle includes a frame member and a tow hook assembly coupled to the frame member. The tow hook assembly includes a tow hook positionable between a first position and a second position, and a locking mechanism operable between a locked position and an unlocked position to permit the tow hook to move into the second position. The vehicle further includes a contact sensor and an electronic control unit communicatively coupled to the tow hook assembly and the sensor, the electronic control unit configured to operate the locking mechanism into the unlocked position to permit the tow hook to be positioned into the second position upon the sensor detecting that a predetermined condition is satisfied.

First claim

What is claimed is:

1 . A vehicle comprising:
a frame member; and a tow hook assembly coupled to the frame member, the tow hook assembly comprising:
a housing;
a tow hook positionable between a first position and a second position, the tow hook movable relative the housing between the first position and the second position, the first position being an extended position and the second position is a retracted position such that the tow hook moves within the housing, and a moving direction of the tow hook between the extended position and the retracted position extending parallel to a vehicle longitudinal direction; and
a locking mechanism operable between a locked position and an unlocked position to permit the tow hook to move into the second position;
a contact sensor; and an electronic control unit communicatively coupled to the tow hook assembly and the sensor, the electronic control unit configured to operate the locking mechanism into the unlocked position to permit the tow hook to be positioned into the second position upon the sensor detecting that a predetermined condition is satisfied.

2 . The vehicle of claim 1 , further comprising a speed sensor detecting a speed of the vehicle, wherein the predetermined condition is satisfied when the speed sensor detects a speed exceeding a predetermined speed threshold.

3 . The vehicle of claim 1 , further comprising a location sensor detecting a location of the vehicle, wherein the predetermined condition is satisfied when the location sensor detects a predetermined location of the vehicle.

4 . The vehicle of claim 1 , further comprising a collision sensor, wherein the predetermined condition is satisfied when data collected by the collision sensor indicates a vehicle collision.

5 . The vehicle of claim 1 , wherein the contact sensor is a pressure sensor coupled to the tow hook, the predetermined condition is satisfied when the pressure sensor detects a force exceeding a predetermined force threshold.

6 . The vehicle of claim 1 , further comprising a tow hook cover positionable between an uncovered position and a covered position to conceal the tow hook when in the second position.

7 . The vehicle of claim 1 , further comprising an actuating mechanism for positioning the tow hook between the first position and the second position.

8 . The vehicle of claim 7 , wherein the actuating mechanism comprises a telescoping rod and a motor for operating the telescoping rod, the telescoping rod extending between a rear wall of the housing and a rear end of the tow hook.

9 . A tow hook assembly comprising:
a tow hook movable between an extended position and a retracted position; and an electronic pressure sensor coupled to the tow hook, wherein the tow hook moves from the extended position to the retracted position in response to the pressure sensor detecting a force exceeding a predetermined force threshold.

10 . The tow hook assembly of claim 9 , wherein the tow hook comprises:
a tow hook body; and an attachment member extending from the tow hook body, the pressure sensor provided on a leading end of the attachment member.

11 . The tow hook assembly of claim 9 , wherein the predetermined force threshold is 1 kN+/−50%.

12 . A method comprising:
positioning a tow hook, movable relative to a housing of a tow hook assembly of a vehicle between a first position and a second position, into the first position, wherein the first position is an extended position and the second position is a retracted position such that the tow hook moves within the housing, and a moving direction of the tow hook between the extended position and the retracted position extending parallel to a vehicle longitudinal direction; positioning a locking mechanism, operable between a locked position and an unlocked position, into the locked position; and in response to determining a predetermined condition is satisfied, operating the locking mechanism into an unlocked position to permit the tow hook to be positioned into the second position.

13 . The method of claim 12 , wherein the predetermined condition is satisfied when at least one of a speed sensor detects a speed exceeding a predetermined speed threshold, a location sensor detects a predetermined location of a vehicle, data collected by a collision sensor indicates a vehicle collision, or a pressure sensor detects a force exceeding a predetermined force threshold.

14 . The method of claim 12 , further comprising positioning a tow hook cover into a covered position from an uncovered position to conceal the tow hook in the second position in response to determining the predetermined condition is satisfied.

15 . The method of claim 12 , wherein the first position is an extended position and the second position is a retracted position such that the tow hook moves within a housing, and a moving direction of the tow hook between the extended position and the retracted position extends parallel to a vehicle longitudinal direction.
