Definitions
- the invention relates to a steering angle sensor, as is required, for example, for yaw angle control of a motor vehicle.
- a value describing the angular position of the steering wheels is supplied to them.
- sensors have been developed, for example, which work with a so-called coding disk, which is non-positively coupled to the steering wheel.
- coding disk which is non-positively coupled to the steering wheel.
- the absolute angular position of the steering wheel can be specified, but not how many revolutions of the steering wheel have already been covered, starting from a neutral position of the vehicle wheels.
- the invention is therefore based on a steering angle sensor of the type resulting from the preamble of claim 1.
- the object of the invention is to provide the possibility in such a steering angle sensor to be able to precisely specify the number of revolutions of the steering wheel just when the steering wheel adjusts when the supply voltage is switched off and thus also when the vehicle is started ⁇ re number of revolutions is present than when the supply voltage is switched off.
- the invention is achieved by the combination of features resulting from the characterizing part of claim 1. Which he- In principle, the invention therefore consists in introducing an additional counter which provides information describing the actual number of revolutions of the steering wheel.
- the information can be given by electrical means, since it is only required when the vehicle's power supply is switched on, because a yaw angle determination to eliminate the risk of skidding is only useful in such cases.
- the mechanical coupling between the code disk and the counter ensures, however, that this is also preparatively set to the correct value when the power supply is still switched off.
- the counter thus follows the change in the steering angle of the wheels even when the supply voltage is switched off, but only provides information when the power supply is switched on again.
- the direction of rotation of the steering wheel determines whether the next number of revolutions are to be added to or deducted from the calculated value. If the steering wheel has therefore made three revolutions clockwise starting from a zero position, the number of revolutions 3 has been reached. If the steering wheel is subsequently turned counterclockwise, then one revolution is not added, but one revolution is subtracted and the number of revolutions is then only 2. The same applies to one revolution of the steering wheel starting from the zero position counter clockwise.
- a particularly simple embodiment for the rotary switch results from the combination of features according to claim 5. Thereafter, a voltage applied to the contact ring designed as a slip ring is applied to one of the circularly arranged contact pieces depending on the number of revolutions. With regard to the evaluation of the number of revolutions Describing electrical signals can also be carried out in such a way that a different resistor is connected to each contact piece and these resistors are connected in parallel with one another. If the internal resistance of the current source is large enough or if a voltage divider is used instead of the individual resistors, the voltage applied to the resistors can be evaluated as the applicable revolution value.
- the combination of features according to claim 7 is recommended as a particularly simple stepping mechanism. According to this, the code disk is connected to at least one switching cam, which switches the switching wheel forward by a corresponding number of teeth of the switching wheel.
- the combination of features according to claim 8 is recommended in a further development of the invention. This involves turning the ratchet wheel around thereby preventing two switching teeth having a height a from lying on a circle with their end faces, which overlaps with the outer circumference of the code disk. Since the teeth cannot be moved due to their great depth, otherwise they will hit the circumference of the code disk, the ratchet wheel is blocked. Between the two drive teeth there is a drive tooth with a lower depth, which ends above the top surface of the code disk. The code disc can therefore rotate under this switching tooth.
- a first switching cam on the code disk takes the flat switching tooth with it, the switching cam on the code disk being followed by a recess, so that the adjacent deep switching tooth can also be rotated.
- the subsequent flat switching tooth is carried along by a second switching cam and, when the deep switching tooth is unscrewed, the following flat switching tooth is moved over the contour of the code disk.
- both the indexing wheel and the code disk are mounted directly in the housing, so that the housing is ⁇ lances specify the distance between the two mutually parallel axes of rotation of the switching wheel and code disk.
- a particularly safe and simple storage for the ratchet wheel is obtained by the combination of features according to claim 10. It is also advantageous that the contact pieces are applied to a circuit board in a manner similar to conductor tracks.
- FIG. 1 shows the housing base 1 of a housing cassette, the housing cover closing the housing not being shown.
- a code disk is rotatably mounted in the housing cover 1.
- the method of operation of the code disk has already been described in the applicant's patent application 195 32 903.1.
- the code disc 2 has an inner ring wall 3 and an outer ring wall 7.
- Spring arms 4 are incorporated into the inner ring wall 3, which with not shown locking hooks on the Attack the underside of the housing base 1 facing away from the viewer and thus secure the code disk 2 against movement out of the viewer level.
- Transport lugs 5, 6 are also formed on the inner ring wall 3 and are indirectly driven by the steering wheel via the code disk, so that the angle of rotation of the code disk with the angle of rotation of the steering wheel (not shown) relative to the vehicle-fixed housing base 1 changes.
- Coding on a sod track in the form of rectangular teeth extending parallel to the axis of rotation of the code disk, which are scanned by detectors (not shown), is used to determine the absolute value of the angle of rotation independently of the previous revolutions of the steering wheel. It is therefore possible to determine the angular position of the code disk within a 360 ° revolution as an absolute value. However, it is not known how many revolutions the code disk had already covered in relation to a central position before the power supply was switched on.
- a switching wheel 8 with switching teeth 9, which are driven by two switching cams 10, 11, is used.
- one of the two switching cams 10, 11 switches the switching tooth 13 located above the cover surface 12 of the code disk 2, which projects into the contour of the code disk 2, by one step.
- the ratchet wheel 8 Since the ratchet wheel 8 has a total of 12 teeth and two teeth are shifted in one step, the ratchet wheel can assume a total of six positions which are assigned to the different numbers of revolutions of the code disc 2.
- the ratchet wheel itself drives a rotary switch.
- a switching ring can be located below the gear wheel, around the edge of which six insulated circular sector-shaped contact pieces are grouped.
- a bow-shaped contact piece is then mounted on the switching wheel itself, which connects the inner contact ring to one of the outer contact pieces, the contact piece which is contacted in each case depending on the angular position of the switching wheel. Since the contact pieces and the contact ring are incorporated into a circuit board, the structure of the rotary switch is very simple. The individual contact pieces merge into output lines on the printed circuit board, while the inner contact ring is supplied with a voltage.
- the voltage at one of the contacts is information about the rotational position of the ratchet wheel and thus the number of revolutions of the code disk.
- the evaluation of the rotary information of the ratchet wheel can take place in such a way that the individual outputs of the contact pieces are guided via resistors, so that the voltage at the outputs connected in parallel can make a statement about the number of revolutions of the code disk.
- other possibilities are also conceivable within the scope of the invention for determining the number of revolutions of the code disk. It is particularly important that the transmission of the rotary movement of the code disk to the shift wheel takes place mechanically, so that even when the power supply is switched off when the front wheels are pivoted, the code disk and thus the shift wheel are also driven. Even in this case, when the vehicle's power supply is switched on, the angular position of the front wheels can be recognized immediately, so that the yaw moment control can immediately react correctly.
