Definitions

  • the present invention relates to a mechanism for controlling movement of a door, primarily for automotive applications.
  • the present invention relates to a door control system that incorporates a damping mechanism.
  • the conventional door check system used to control movement of the pivoting side door of a passenger vehicle includes a hinge disposed between the door pillar and one side of the door, and a mechanical stop or check for controlling the pivoting movement of the door.
  • the stop mechanism typically includes a cam secured to the pivoting side of the door, and a pawl that extends from the door pillar.
  • the pawl consists of an arm fitted with a roller bearing at one end, and the cam has a number of detents for receiving the roller therein.
  • the roller becomes momentarily trapped within each detent, thereby temporarily preventing further movement of the door.
  • the detents are sufficiently shallow so as to allow the door to be moved from one stop position to the next stop position by exerting minimal additional force against the door.
  • the conventional door control system is widely used in most passenger vehicles, more often than not the stop mechanism provides the passenger with a pair of stop positions, an inner and outer position. Also, to allow the passenger to move the vehicle door easily between the opene and closed positions, the pawl must be resiliently received within the detents. As a result, the latch side of the vehicle door tends to oscillate when the door reaches a stop position, thereby increasingly the likelihood of the door striking the adjacent vehicle. Accordingly there remains a need for a door control system that allows the door to stop at any desired position and reduces oscillating movement in the door.
  • the disadvantages of the prior art may be overcome by providing a door control system that is capable of holding a door in any open position up to and including a full open position.
  • the invention accomplishes this by providing a reciprocating member pivotally mounted to a door hinge.
  • the reciprocating member such as a piston, is slidingly mounted in a fluid-filled cylinder in which the viscosity of the fluid can by varied by a control mechanism.
  • a door control system can be provided that prevents a door from contacting objects as the door is being opened.
  • a door control system that includes a door check assembly, a hinge assembly, and a controller.
  • the door check assembly includes a housing having a cylinder, a piston and magnetorheological fluid disposed within the cylinder, and at least one fluid passageway disposed within the housing. The fluid passageway receives the magnetorheological fluid therein for damping movement of the piston within the cylinder.
  • the door check assembly also includes a magnetic flux generator configured for generating magnetic flux within the fluid passageway and a position sensor providing feedback signals corresponding to position and velocity of the door to the flux controller.
  • the hinge assembly includes a pivoting member coupled to the piston, and is configured for attachment to a door.
  • the controller includes an obstacle sensor configured for attachment to the door, and magnetic flux controller coupled to the flux generator. The magnetic flux controller is configured to effect changes in the magnetic flux, and is in communication with the proximity sensor for controlling movement of the door in accordance with sensor data received from the sensor.
  • a hinge having a first hinge member and a second hinge member pivotally coupled to the first hinge member.
  • a door check assembly is pivotally coupled between the first hinge member and the second hinge member.
  • the door check assembly includes a piston slidably mounted for reciprocating movement in a fluid-filled cylinder, and means are provided for controlling the viscosity of the fluid within a portion of the cylinder.
  • a hinge that includes a first hinge member, a second hinge member pivotally coupled to the first hinge member, and a door check assembly coupled to the first hinge member.
  • the door check assembly includes a housing having a position sensor, a cylinder, a piston and magnetorheological fluid disposed within the cylinder, and at least one fluid passageway disposed within the housing.
  • the piston is pivotally coupled to the second hinge member, and the fluid passageway receives magnetorheological fluid therein for damping movement of the piston within the cylinder.
  • the hinge also includes a magnetic flux generator configured for generating magnetic flux within the fluid passageway.
  • the door control system is used as an infinite door check to hold the door in any open position between closed and fully open positions.
  • the door control system is used to control the movement of the pivoting side door of passenger vehicle.
  • the hinge assembly includes a base member secured to the housing and the door pillar, and the pivoting member is pivotally coupled at one end to the base member, and at the opposite end to the side door.
  • the cylinder comprises an axial bore that extends axially through the housing, and the piston comprises a piston axially moveable within the cylinder.
  • the fluid passageway communicates between opposite sides of the piston and may be disposed within the piston, or between the piston and the housing.
  • the sensor comprises a capacitive proximity sensor that senses the proximity of obstacles to the door, and the controller is configured to restrict movement of the door when in proximity to the sensed obstacles.
  • the controller is configured to progressively reduce the flow rate of the magnetorheological fluid through the passageway to thereby progressively reduce the speed of movement of the door. In this manner, the controller reduces the likelihood of the door striking an obstacle, such as the side door of an adjacent passenger vehicle, as the passenger door is opened.
  • the door control system has a door position feedback sensor to enable the controller to determine door velocity, absolute position, and dead band position and responsively control the movement of the door as it is closed, preventing the door from slamming into and damaging the striker.

  • the door control system 100 is not limited for use with the pivoting side door 108 of a vehicle, but may also be used for other applications, such as to control the rear hatch of a hatch-back vehicle, a sliding door of a van or the sliding rear window of truck. In the case of the sliding truck window, the door control system 100 could be used as a window lock, that is released when a proximity sensor disposed adjacent the window is activated.
  • Fig. 2 shows the door check assembly 102 and the hinge assembly 104 disposed between the door pillar 110 and the pivoting end of the side door 108 of the passenger vehicle.

  • a magnetic flux generator 126 generates magnetic flux within the fluid passageways.
  • the fluid passageways may be provided as apertures extending axially through the piston 118, or as apertures disposed between the piston 118 and the housing 114.
  • the fluid passageway allows the magnetorheological fluid therein to flow between opposite sides of the piston 118 and thereby allow the piston to move axially within the cylinder 116.
  • the flux generator comprises a bobbin disposed within the piston 118, a wire coil wound around the bobbin, and a plastic layer encapsulating the wire coil.
  • the wire coil is connected to wire leads that extend through the tubular rod portion 122 of the connecting rod.
  • the wire leads terminate in a suitable electrical connector 128 that allows the controller 106 to interface with the flux generator.
  • the hinge assembly 104 comprises a base or first member 132, and a pivoting or second member 130 pivotally coupled to the base member 132.
  • the pivoting member 130 is secured to the door of the passenger vehicle, and is pivotally coupled to the housing 114 via apair of pins 131 that allow the housing 114 to pivot as the side door 108 of the passenger vehicle moves between the opened and closed positions.
  • the pivoting member 130 has a generally U-shape, incorporating a pair of substantially parallel arms 134a, 134b that define an elongate channel therebetween.
  • the control rod portion 124 of the control rod of the door check assembly 102 extends through the channel, and is pivotally connected to the base member 132 via a pin 133.
  • the base member 132 also has a generally U-shape, incorporating a pair of substantially parallel arms 136a, 136b that are pivotally coupled to the parallel arms 134 of the base member 132 via a pin 137.
  • the base member 132 includes an attachment plate 138 for securing the base member 132 to the door pillar 110 of the passenger vehicle. Accordingly, the base member 132 and the pivoting member 130 of the hinge assembly 104 pivotally connect the side door 108 to the passenger vehicle.
  • the controller 106 includes a proximity sensor 140, inner and outer door latch sensors 142a, 142b, and a magnetic flux controller 144 in communication with the proximity sensor 140 and the door latch sensors 142.
  • the proximity sensor 140 senses the proximity of the side door 108 of the vehicle to obstacles, such as posts or adjacent vehicles, which may be encountered as the door moves from the closed to the fully open positions.
  • the obstacle or proximity sensor 140 comprises a capacitive sensor that is secured to the outer surface of the door panel.

  • the proximity sensor 140 may take the form of other contact or non-contact sensor technologies, including touch pads, infrared sensors and microwave sensors.
  • other sensors may be provided on different locations on the door to sense other events. For example, sensors can be packaged beneath the exterior window trim or belt molding to sense a "push close" feature.

  • the magnetic flux controller 144 is electrically connected to the speed/position sensor 119, proximity sensor 140, the door latch sensors 142 and the flux generator 126 through suitable electrical cabling.
  • the controller 106 is manufactured using dedicated electronics hardware. Alternately, however, the controller 106 may be manufactured as a software-based controller, having a central processing unit (CPU) and a non- volatile memory (ROM) in communication with the CPU, with the ROM having software routines that allow the controller 106 to perform, the functions of the dedicated magnetic flux controller 144.
  • CPU central processing unit
  • ROM non- volatile memory
  • the magnetic flux controller 144 is configured to monitor the proximity data received from the proximity sensor 140, and to apply a voltage to the wire coil 126 when the proximity data indicates that the side door 108 of the vehicle is in proximity to an obstacle.
  • the applied voltage will increase the strength of the magnetic field induced in the fluid passageways, thereby causing the viscosity of the magnetorheological fluid disposed in the fluid passageways to increase.
  • the flow rate of the magnetorheological fluid through the fluid passageways will be reduced, thereby restricting axial movement of the piston within the cylinder 116 of the door check assembly 102.

In this manner, the magnetic flux controller 144 is able to dampen oscillations in the movement of the door 108 that could otherwise occur if the door 108 was stopped suddenly.
  • the corresponding door latch sensor signals the magnetic flux controller 144, thereby triggering the magnetic flux controller 144 to begin monitoring the proximity sensor data.
  • the proximity sensor 140 provides the magnetic flux controller 144 with proximity data that indicates the proximity of obstacles to the side door 108.
  • the magnetic flux controller 144 does not apply a voltage to the wire coil 126, thereby allowing the magnetorheological fluid to flow freely through the fluid passageways and allowing the piston to move freely within the cylinder 116 of the door check assembly 102. As a result, the vehicle occupant will be able to pivot the side door 108 outwardly in the usual manner.
  • the magnetic flux controller 144 applies a small voltage to the wire coil 126, thereby causing a corresponding small restriction in the movement of the magnetorheological fluid through the fluid passageways.

  • the magnetic flux controller 144 continues to reduce the angular speed of the side door 108 until the distance between the side door 108 and the obstruction is less than a threshold amount, at that time the magnetic flux controller 144 prevents further angular movement of the side door 108, as shown in Fig. 6.
  • a speed arid position sensor 119 may be mounted on the housing 114 to sense movement of the piston 118 relative thereto.
  • the sensor 119 may be mounted on one of the hinges 104, 112 to sense angular speed of the door 108 relative to the vehicle pillar 110.
  • the speed and position sensor 119 consists of a sensor capable of determining rate of change and position and thereafter providing a feedback signal to the controller 106. Such sensors are well known in the art.
  • the controller 106 can be programmed and configured in a manner well known in the art to provide variable dampening based upon position and rate of change of position or door velocity.
  • a change in position relative to a stopped position can allow an external force to provide stimulus to the control system 100 to reduce the magnetic flux and allow a manual positioning of the door 108 without the use of the inside or outside handle sensors 142.
  • a dead band from the fully closed to a partially opened position allows a desirable initial force free acceleration of the door 108 to open.
  • the magnetic flux controller 144 is energized to lock the piston 118 relative to the door check assembly 102 and thereby hold the door 108 in position. Additionally, if the signals from the inner door latch sensor 142a or the outer door latch sensor 142b terminate, the magnetic flux controller 144 is activated to hold the door 108 in position.
  • the vehicle occupant To close the side door 108, the vehicle occupant again momentarily lifts one of the door latch release handles, causing the corresponding door latch sensor to signal the magnetic flux controller 144.
  • a change in position of the door 108 whose predetermined characteristic rate of change assumes that a vehicle occupant may be attempting to open or close the door.
  • the magnetic flux controller 144 removes the voltage from the wire coil 126, thereby allowing the magnetorheological fluid to flow freely through the fluid passageways and the piston to move freely within the cylinder 116 of the door check assembly 102.
  • the vehicle occupant will be able to pivot the side door 108 in the usual manner.
  • control system 100 can detect a hand reaching for a door handle, either interior or exterior.
  • the control system 100 responsively releases the door to allow movement thereof.
  • a further feature of the present invention is the ability to control excessive slamming of the door. If the sensor 119 senses a speed of the door 108 above a predetermined value, the door control systems 100 can be responsively activated to slow the door 108 below the predetermined value. In this manner, the door 108 can be prevented from over-slamming against the striker.
  • Conventional magnetorheological fluid dampers typically employ an electromagnet to provide variable control from zero to maximum viscosity of the fluid medium. Electric current is required to hold the viscosity to a desired value.
  • Another approach to controlling the fluid medium utilizes a magnetic circuit consisting of a permanent magnet for maximum viscosity and an electromagnet to lower the viscosity. This arrangement sees the magnetic poles in a field opposing arrangement where the net effect of the magnetic circuit is dependent upon the controlling current in the electromagnet. The advantage of this arrangement is that no current is required for maximum viscosity of the fluid.
  • Another arrangement sees the permanent magnet provide a bias field to the magnetorheological fluid and the electromagnetic circuit increases or reduces the magnetic bias and therefore the viscosity of the fluid. The advantage in this arrangement is reduction in current required by the electromagnet for a given viscosity of the magnetorheological fluid.
