Abstract

The handhold (1) has a fixing section, with which an operating section is fixed with a fixing panel. The sensors are assigned to the fixing section, where the sensors release signals depending on the adjusted tension or pressure on the operating section at an electronic control unit from the direction of tension or pressure, particularly for locking or unlocking of the door lock or for opening or closing the motor vehicle door or a window. The operating section is provided with the fixing section and is attached with the fixing panel.

Description

The The invention relates to a handle for a motor vehicle door with at least one attachment portion, with which an operating portion is attached with a mounting bracket.

door handles of motor vehicles have different shapes. There are ironing handles, at the two strap ends each have a mounting portion have, with which they are attached to a mounting bracket. The handle is usually present a recessed grip, which is formed by the door skin. The mounting bracket is located on the door skin inside. In addition to the bar handles, there are also folding handles. These are hook-like and with a mounting portion connected to the mounting bracket. Less common are knobs.

at the known door handles is the operating section movable relative to the mounting bracket. At the top described handles, the movement consists of a pivoting movement. Out the pivoting movement of the operating section opposite the mounting bracket becomes a mechanical opening operation derived. In any case, the operating section opposite the mounting bracket by a certain distance be displaced, so over this route a switch can be actuated, or the displacement of a mounting portion acts on a Bowden cable with which a lock can be unlocked can.

These required in the prior art mechanical distancing of Operating section opposite mounting bracket is prone to failure.

The DE 102004034509 A1 shows a motorized operation of a sliding door by means of micro-switches, which are actuated by grip movement. By Actuate supply of the handle in the respective direction, the sliding door can be opened or closed.

The DE 19824427 C1 describes a bow handle, which can be pivoted from its neutral position downwards or upwards to actuate electrical switches. With the operation of the switch an identification or a lock or unlocking can be triggered.

The DE 10300572 A1 describes a door handle for power assisted opening of a vehicle door. The door handle includes a capacitive sensor, for example, which detects a manual deflection, ie relative movement of the door handle relative to the door.

outgoing from the aforementioned prior art and the associated technical Disadvantages of the invention is the object of a generic To further develop the handle in accordance with use.

The object is achieved by the invention specified in the claims, each claim represents an independent solution to the problem and can be combined with any other claim. First and essentially it is proposed that force sensors are assigned to the attachment section. These generate sensor signals which depend on the train or pressure directed onto the actuating section. The sensor signals depend not only on the direction of the train or the pressure, but may also depend on the strength of the train or pressure. An electronic control device generates actuating signals for locking / unlocking a door lock and / or for opening or closing the motor vehicle door from these sensor signals. The locking / unlocking of the door lock takes place in an electromechanical manner. The actuation signal is converted into an electrical signal which unlocks or locks the door lock. The actuating signals can also be used to open or close a motor vehicle door. For this purpose, a motor is driven by the actuating signals. With this engine, for example, a sliding door can be opened or closed. The sensors respond to forces exerted on the operating portion of the handle. The sensors react differentiated in each spatial direction and on the sign of the forces. Thus, for example, a pressure exerted on the actuating portion in the horizontal plane can lead to a locking of the closure or to a closing of a sliding door. In contrast, a train applied in the horizontal direction, ie a force with opposite signs, can initiate the opening of a motor vehicle closure or the sliding out of a sliding door from its closed position. Alternatively or additionally, a force application upwards or downwards can lead to a locking or unlocking of a motor vehicle closure. But it is also possible to use this application of force up or down to drive a window regulator. If the force is introduced upward in the operating portion of the handle, the window is closed. On the other hand, if the force is introduced down into the operating section, the window is opened. In the case of a motor-driven door, application of force in the direction of travel or the direction of travel is preferably converted into actuation signals for the drive motor for the door. For example, a force application of the operating portion to the rear to open the door and a Kraftbeauf slam forward to close the door. This variant is preferred for sliding doors application. In this case, a force-proportional actuating signal can preferably be generated. With the force-proportional signal, it is possible to influence the travel speed of a sliding door. Increased tension in the direction of movement increases the speed and lowers it by pulling in the opposite direction until the movement of the sliding door stops or reverses the movement. The application of the handle according to the invention takes place not only on motor vehicle sides doors, but also on rear doors or tailgates. Here too, a force-proportional actuating signal is preferably generated in order to open or close the tailgate by motor. As sensors strain gauges, force sensors, Hall sensors, pressure sensors, optical sensors, non-contact capacitive sensors, inductive sensors or gyro sensors are considered. In the case of the handle according to the invention, the actuating section is firmly connected to the fastening bracket via the fastening section, since no or only little distancing is required for the operation. So it is not a change in position in the sense of an actuating travel of the operating section relative to the mounting bracket required. It is essential only a slight play of movement of the operating section to trigger the sensors. If the sensors are located in the region of the attachment section, then the latter must be able to shift slightly, so that sensors designed as pressure sensors sense the pressure load or sensors that are designed as strain gauges can perceive an expansion or compression. Other components which can be triggered mechanically with little force are preferably not provided in the handle according to the invention. The electronic control device is able to distinguish the individual sensor signals from each other, depending on the direction in which the handle is moved to deliver other actuation signals, so that other functions are triggered. This evaluation unit formed by the electronic control device can optionally be arranged in a handle bar or in the fastening console. The handle has a fixing device, with which the actuating portion, for example, a handle is held in its zero position. From this zero position of the operating portion or the handlebar can be operated via small ways. These paths are in the range of a few millimeters or preferably even in a range <2 mm, or <1 mm. There are provided elastic elements to return the handle after the application of force back to its zero position. The sensors may optionally be associated with the mounting portion, the operating portion or the mounting bracket. The handle according to the invention can form a fastening section and then have the outer contour of a conventional folding handle. In addition, the handle according to the invention can also have two fastening sections and thus have the shape of a conventional bow-type handle. It is sufficient if one of the two attachment sections, the force sensors are assigned. The sensors are preferably arranged adjustable on the attachment portion, on the actuation portion or on the attachment bracket. It is also possible to arrange the sensor on the inside of a handle bracket. The handle is then part of a mounting portion. The actuating portion is then on the inner surface of the handle bracket. There, then the force sensor is arranged. The power can be absorbed via an elastic zone in the handle.

A cross section through the handle 1 is in the 2 shown. The coordinate system drawn there shows a backward X-axis, an upward Z-axis and a Y-axis directed from the left side of the vehicle to the right side of the vehicle.

The handle 1 has an operating section 4 which is designed as a handle. Each of the two ends of the operating section 4 forms an extension, which has a fastening section 3 or a fastening section 2 formed. With the two attachment sections 2 . 3 is the handle (operating section 4 ) with a mounting bracket 5 connected. The mounting bracket 5 is located at the back of a recessed grip 8th on the inside of the door skin. The attachment sections 2 . 3 are essentially immovable with the mounting bracket 5 and the operation section 4 connected. With the reference numbers 6 . 7 Force sensors are indicated. These force sensors are able to absorb forces from the operating section 4 in the mounting bracket 5 be initiated to convert into electrical signals. Here are the force sensors 6 . 7 able to distinguish between the different directions of force. The force sensors 6 . 7 In addition, they are able to deliver force-proportional signals.

In the 1 The three spatial directions are shown in which the force sensors 6 . 7 provide differentially evaluable signals.

The of the force sensors 6 . 7 emitted signals are supplied to an electronic control device, not shown, having an evaluation unit. Thus, the sensor signals are converted into actuation signals, it being possible to distinguish whether the force applied to the actuation section 4 is applied in the plus X direction, in the minus X direction, in the plus Y direction, in the minus Y direction, in the plus Z direction or in the minus Z direction. Depending on the direction of the force, the electronic control unit emits different actuation signals to unlock or lock a door lock, drive an electromotive door drive, stop or change the direction of movement, or raise or lower a window.

When in the 1 shown sliding door, for example, a lifting of the operating section 4 Thus, a force in the Z direction lead to a closing of the rear window or even to unlock the door lock. A lowering of the operating portion 4 in the minus Z direction, however, can lead to a lowering of the window or to a locking of the door lock.

Preferably, the following use of the actuating signals, after which a force application of the actuating portion 4 in minus Y direction, ie in the direction of the motor vehicle has a locking of the door closure result. A train on the operating section 4 , Thus, a force in the positive Y-direction, however, has an unlocking of the closure result.

Will the operating section 4 in the plus-X direction, ie operated in the rearward direction, the sliding door is opened. Will the operating section 4 operated in minus X direction, the movement of the sliding door drive is stopped or the sliding door in the opposite direction, ie driven in the closing direction.

As force sensors 6 . 7 come different sensor elements into consideration, such as strain gages, Hall sensors, pressure sensors, optical sensors, non-contact capacitive sensors, inductive sensors, gyro sensors or piezo elements.

That in the 3 to 8th illustrated first embodiment has a mounting bracket 5 , the inside of the door a recessed grip 8th can be attached. The operating section 4 is here formed by a handle, with a ers th attachment section 2 who is a grip camp 22 forms, and with another attachment section 3 holding a handle dome 10 training, at the mounting bracket 5 is attached.

The Griffdom 10 of the prior art handles relative to the mounting bracket 5 is movable, is with a mounting arm 14 at a landing stage 11 attached. The holding bridge is again on support arms 20 the mounting bracket 5 attached. The one piece from the mounting bracket 5 trained support arms 20 are with the jetty 11 via fastening bolts 19 pinned. The jetty 11 carries a pedestal 15 from which a square mounting arm 14 protrudes. The end face of the attachment arm 14 sits in a pin 13 continuing, the form-fitting in a bore 12 of the Griffdomes 10 intervenes.

In the handle described in the first embodiment, the attachment arm 14 a bending body. The attachment arm 14 owns as well as the Griffdom 10 a square cross section with mutually perpendicular square surfaces. There is a strain gauge on each of the four square surfaces 7 that has a connection cable 16 is connected to an electronic control unit, not shown.

Depending on the direction of force in the handle, so in the operating section 4 becomes the square mounting arm 14 bent around a space axis. This bend is detected by the strain gauges. The associated sensor signals are forwarded to the control device so that it forms actuating signals in the manner described above.

To generate these sensor signals, there is no significant shift of the operating section 4 required. It is only a slight bending of the attachment arm 14 required.

Instead of four strain gauges 7 can also only two strain gauges 7 be provided.

That in the 9 to 12 illustrated second embodiment has substantially the same structure as the first embodiment described above. Also here is the handle camp 22 firmly with the mounting bracket 5 hooked and the Griffdom 10 immovable on the mounting bracket 5 attached.

The Griffdom 10 is formed by a square arm, with which the actuating portion 4 with the mounting bracket 5 connected is. On the four square surfaces of the Griffdomes 10 sit strain gauges 7 to move to the operating section 4 to convert applied forces into sensor signals, which are converted into actuation signals as described above. The attachment arm 14 has only a holding function in this embodiment.
