Description

ABS detection device for a motor vehicle

Technical Field

The utility model relates to an ABS detection device for a motor vehicle.

Background

In automobile manufacturing, after the automobile is manufactured in a manufacturing workshop and before the automobile is delivered out of a factory, a series of tests are finally carried out in the workshop, wherein the tests comprise ABS anti-lock tests of the automobile. However, the vehicle is prone to yaw or deflection before or during ABS detection, which requires the vehicle occupant (or driver) to constantly steer the vehicle and its four wheels, i.e., to perform a centering operation, in order to acquire the required ABS detection data.

At present, the centering of the vehicle is basically completely performed by the experience and feel of the inspector, but this is difficult especially for inexperienced new employees, since the new employees often find the correct centering position incorrectly, resulting in slow progress of the ABS detection procedure. This lengthens the tact time of the vehicle and is therefore particularly disadvantageous for mass production of vehicles.

To the extent that a term or phrase is intended to have a special meaning, i.e., a meaning other than that understood by skilled artisans, such a special definition will be expressly set forth in the specification in a definitional manner that directly and unequivocally provides the special definition for the term or phrase.

Throughout the following description, unless the context requires otherwise, the words "comprise", "comprising", and variations thereof, such as "comprises", "comprising", and "having", will be interpreted in an open, inclusive sense, i.e., as "including but not limited to".

The ABS detection apparatus for a motor vehicle 1 of the present invention may be arranged in a manufacturing shop of the motor vehicle 1 for performing qualification detection of an ABS anti-lock system (hereinafter, abbreviated as ABS) of the motor vehicle 1 before shipment. The motor vehicle 1 may be any vehicle equipped with an ABS, such as a car or a sedan.

Referring to fig. 3, the ABS detection apparatus may include an ABS detection station 2, and the ABS detection station 2 may be driven by the vehicle 1 and may perform ABS acceptability detection on the vehicle 1 thereon. The ABS test station 2 may comprise two ABS test zones 3 assigned to the front and rear wheels, respectively, and the ABS test zones 3 may have a rectangular shape and be able to be driven in by the wheels and support and drive them. The ABS detection region 3 may comprise a drivable wheel (not shown), for example a steel wheel, assigned to a wheel of the motor vehicle 1. Two such rollers can be associated with each wheel, which rollers have longitudinal axes parallel to one another and are arranged in front of and behind the wheel. During the ABS detection, the roller may be electrically driven, and the rotating roller may rotate the wheel to simulate the driving state of the vehicle 1.

The ABS detection apparatus may include an ABS detection control device (not shown) which may control the entire ABS detection process including the start and end of ABS detection and the collection and analysis of ABS detection data, etc.

The ABS detection device may comprise a centering system which may assist an in-vehicle inspector in centering the vehicle 1 during or before ABS detection of the vehicle 1. In this context, "centering" of the motor vehicle 1 is to be understood to mean that the motor vehicle 1, which is about to deflect or yaw, is aligned by rotating the steering wheel 4, i.e., the wheels and the body are adjusted in the direction of the simulated driving direction of the motor vehicle 1, such that the longitudinal axis of the wheels can be oriented substantially parallel to the longitudinal axis of the wheels of the ABS test station 2, and the longitudinal axis of the motor vehicle 1 can be oriented substantially perpendicular to the longitudinal axis of the wheels. The purpose of "centering" is, for example, to bring the motor vehicle 1 into a predetermined position range at or near the centering position for as much time as possible, since the ABS detection data required for ABS detection can be better acquired in this position range.

The centering system may comprise a laser emitting device 5 (see fig. 1), and the laser emitting device 5 may assist in centering the motor vehicle 1, in particular by: the laser emitting device 5 can emit a laser section 27 to the interior of the motor vehicle 1 through the windshield 6 of the motor vehicle 1, and an inspector in the vehicle can use the laser section 27 as a reference to conveniently center the deflected motor vehicle 1. In some embodiments, the inspector may also be a human, but a robot or other suitable automated device that can perform automated centering of the motor vehicle in place of a human, which can read the information of the laser segment 27.

The laser emitter device 5 can be designed as a line laser emitter device 5 which can emit a line laser 8, for example a line laser 8 or a cross-line laser 8, the line laser 8 emitted by which can penetrate at least in sections through the windshield 6 of the motor vehicle 1 into the interior of the motor vehicle 1 and thus impinge, for example, on an instrument panel 19 of the motor vehicle 1, for example in the center of the instrument panel 19 of the motor vehicle 1 (see fig. 4 and 5).

Fig. 1 schematically shows an embodiment of a laser emitting device 5. In this embodiment, the laser transmitter 5 may have a laser 9 for emitting a linear laser 8, a collar 10 fitted over the laser 9 and fixing the laser 9, a support 11 supporting the collar 10, and a pallet 12 supporting the support 11. In this embodiment, the laser 9 is not pivotable. The laser emitter device 5 can be fastened with its support plate 12 to a stationary object outside the motor vehicle 1, for example to an existing workshop fence 13, to a ceiling or to a specially associated support.

Fig. 2 schematically shows the main components of the laser 9, including a laser diode 14 that emits laser light, a collimating lens 15 that can collimate the laser light, and a cylindrical lens 16 that emits the collimated laser light 8 in a line shape or a cross-hair shape.

Fig. 3 shows a top view of a motor vehicle 1 located directly above the ABS detection area 3 of the ABS detection station 2. A line or cross laser 8, which is irradiated by the laser 9 onto the motor vehicle 1, may include three laser segments 7, 17, 27, namely, a first laser segment 7 (see fig. 3) of a line shape located on the engine cover of the motor vehicle 1 and a second laser segment 17 (see fig. 3) of a line shape located on the ceiling of the motor vehicle 1, and a third laser segment 27 (see fig. 4) of a line shape or a third laser segment 27 (see fig. 5) of a cross shape irradiated onto the dashboard 19 through the windshield 6 of the motor vehicle 1.

The laser 9 may be connected to the electrical grid in the shop to ensure that the emitted laser light 8 is sufficient to penetrate the camouflage film on the windscreen 6 into the car and that the third laser segment 27 entering the car has sufficient brightness or clarity to enable an inspector to easily view the third laser segment 27 in the car.

The laser emitting device 5 may be arranged above or in front of the motor vehicle 1, for example in the longitudinal center plane of the motor vehicle 1. The laser 9 can be directed with its front end towards the vehicle 1, for example towards the windscreen 6 of the vehicle 1. The laser light 8 emitted by the laser 9 can be focused so that the focus can be adjusted at the motor vehicle 1, so that the third laser section 27 entering the motor vehicle 1 maintains a sufficient brightness.

In some embodiments, the laser 9 may be pivotable, for example pivotable relative to the strut 11 by means of a pivot or cardan shaft. The angle of the laser 9 can thus be adjusted to better aim the motor vehicle 1.

In some embodiments, the laser emitting device 5 may have a position adjustment mechanism (not shown) by means of which the position of the laser 9 can be adjusted in the transverse direction of the motor vehicle 1, so that the laser 9 is movable in the transverse direction of the motor vehicle 1. By moving the laser 9 laterally, the third laser section 27 in the vehicle can be moved in the lateral direction of the motor vehicle 1 to a position which is convenient for the inspector to observe, for example, the lateral center of the instrument panel 19. This is advantageous because, when driving different motor vehicles 1 onto the ABS test stand 2, the test person can experience a more or less lateral offset, so that the third laser section 27 in the motor vehicle 1 cannot always be located in the optimum viewing position, for example the lateral center of the dashboard 19. The laser emitting device 5 can compensate for this lateral offset of the motor vehicle 1 by means of its position adjustment.

The position adjustment of the laser transmitter 5 can be performed automatically. For this purpose, the centering system may comprise a motor vehicle position detection device (not shown) which can detect the position, for example the transverse position, of a motor vehicle 1 which is moving into an ABS detection region 3 of the ABS detection station 2. The motor vehicle position detection means can be connected in communication with the position control means of the laser emission device 5, so that the position signal of the motor vehicle 1 detected by the motor vehicle position detection means can be transmitted to the position control means of the laser emission device 5, and the position control means can automatically adjust the position of the laser emission device 5 on the basis of the position signal, so that the position of the third laser section 27 in the vehicle is always at the optimal observation position in the motor vehicle 1.

For a line laser 8, the plane in which the three laser sections 7, 17, 27 extending in the longitudinal direction of the motor vehicle 1 impinge on the motor vehicle 1 can be the longitudinal center plane of the motor vehicle 1 or parallel thereto. A third laser segment 27 (see fig. 4) in the shape of a wordline can be considered by the detector as a laser reference for the motor vehicle 1. In addition, the inspector can use the interior trim portion of the vehicle 1 near the third laser segment 27 as a vehicle reference against which the third laser segment 27 is compared.

The vehicle reference may be a dot, such as a dual flashing light 18. The third laser section 27 extends past the point without the motor vehicle 1 deflecting, and when the motor vehicle 1 deflects the point moves away from the third laser section 27, in which case the inspector can move the motor vehicle 1 by rotating the steering wheel 4 so that the point is again located on the third laser section 27 to achieve centering.

The automotive reference object may also be a thread, for example an interior thread or a thread edge of an interior thread. The third laser section 27 runs parallel to or coincides with the thread without the motor vehicle 1 deflecting, whereas when the motor vehicle 1 deflects, the thread runs obliquely and no longer parallel to or coincides with the third laser section 27, at which point the inspector can move the motor vehicle 1 by rotating the steering wheel 4 so that the thread runs parallel to or coincides with the third laser section 27 again to achieve centering.

The crosshair laser 8 differs from the one-line laser 8 only in that a further laser segment section is provided on the third laser segment 27, which extends in the transverse direction of the motor vehicle 1 on the dashboard 19. The function of this transverse laser segment section is the same as that of the vertical laser segment section of the third laser segment 27, which additionally provides a transverse laser reference. This allows the inspector to additionally select other dots or transverse threads of the interior trim part of the motor vehicle 1 as motor vehicle reference objects. The third laser segment 27 in the shape of a cross makes it easier for the inspector to find a suitable vehicle reference for centering the vehicle 1.

The laser emitting device 5 may have a switch mechanism (not shown) by which the opening and closing of the laser 9 can be controlled. The switching mechanism may be in communicative connection with the ABS detection control device. Provision may be made that, when the ABS detection control device initiates the ABS detection process, the switching means can be opened simultaneously to switch on the laser 9 to emit laser light 8; and the switching mechanism can be simultaneously turned off to turn off the laser 9 when the ABS detection control means turns off the ABS detection process. The laser 9 can thus be kept on only during the ABS detection of the motor vehicle 1, and is switched off at all times, thus saving electrical energy.

It is of course also conceivable to provide sensors (not shown) in the ABS detection region 3, which sensors can detect the entry and exit of the wheels of the motor vehicle 1 into and out of the ABS detection region 3. The sensor may be in communicative connection with the switching mechanism. Provision may be made for the switching mechanism to be opened simultaneously when the sensors detect that the wheels of the motor vehicle 1 are driven into the ABS detection region 3, in order to switch on the laser 9 to emit laser light 8; and the switching mechanism can be switched off simultaneously to switch off the laser 9 when the sensor detects that the wheels of the motor vehicle 1 have moved out of the ABS detection region 3. The laser 9 can thus be kept on only during the time when the wheels of the motor vehicle 1 are in the ABS detection zone 3, and is switched off at all times, thus saving electrical energy. The sensor may be a position sensor that detects the position of the wheel, a pressure sensor that detects the pressure applied by the wheel, or the like.

The following exemplary operation steps of the detection process for a motor vehicle of the ABS detection system for a motor vehicle 1 according to the utility model are described:

the method comprises the following steps: the inspector drives a motor vehicle 1 into the ABS test platform 2 and supports the wheels on the rollers of the ABS test area 3;

step two: the ABS detection control device starts ABS detection and controls the switch mechanism to start the laser 9 at the same time;

step three: in the ABS detection process, the inspector refers to the laser section 27 in the vehicle to adjust the steering wheel 4, so that the vehicle keeps centered until the ABS detection process is finished;

step four: the ABS detection control means turns off the ABS detection and at the same time controls the switching mechanism to turn off the laser 9.

The switching on and off of the laser 9 in steps two and four can alternatively also be controlled by the above-mentioned sensors arranged in the ABS detection zone 3, as described above. This switching of the laser 9 by means of the sensor advantageously enables the inspector to perform a preliminary centering of the motor vehicle 1 with reference to the laser section 27 after the motor vehicle 1 has entered the detection area and before the ABS detection has been initiated.

The technical effects that can be achieved by the ABS detection device for the motor vehicle 1 of the present invention include, but are not limited to: the line-shaped laser section 27 emitted by the laser 9 into the vehicle makes it possible to provide the vehicle 1 with a centering reference in the vehicle for the inspector to see during or before the ABS test. The inspector can quickly find the offset or yaw of the motor vehicle 1 by referring to the laser section 27 in the vehicle and can quickly center the motor vehicle 1 by referring to the laser section 27, thereby avoiding the inspector from judging whether the motor vehicle 1 is centered only by experience, so that the opportunity of effectively sampling data in the same time can be remarkably increased, and the detection process time is reduced, namely the ABS detection time of each vehicle is saved. Practice shows that the ABS detection process of each trolley can be shortened by more than ten seconds, which is considerable for the production beat of only one minute or more for producing one trolley. Furthermore, the advantage of using the laser section 27 as a centering reference is that the first, laser light 8 is an optical signal, which does not interfere with the movement of the motor vehicle 1. Secondly, the laser 9 can be conveniently controlled to be opened and closed, and the opening and closing process can be conveniently cooperated with the ABS detection process to save electric energy. Third, the laser segment 27 may be directed into the cockpit and may be referenced by the subject in direct close proximity. This is far more advantageous than placing an object outside the motor vehicle 1 as a reference, since on the one hand an inspector inside the vehicle cannot easily observe an outside object, and on the other hand an object may scratch the motor vehicle 1.

Finally, it is noted that the above-mentioned embodiments are only for understanding and explaining the present invention, and do not limit the scope of the present invention. It will be apparent to those skilled in the art that modifications may be made in the foregoing embodiments, all without departing from the scope of the utility model.
