Definitions
- the invention relates to a wheel suspension for a vehicle, comprising a wheel carrier, a vehicle wheel, which is rotatably mounted on the wheel carrier, at least one coupling member, by means of which the wheel carrier is pivotally connected to a structure of the vehicle, at least two joints, one of which between the Coupling member and the wheel carrier and another is connected between the coupling member and the structure, and at least one integrated in a first of the joints and at least one angle sensor having measuring means by which the deflection of the first joint is detected or can. Furthermore, the invention relates to the use of an angle sensor and a method for correcting angular errors.
- a vehicle mounted acceleration sensor system is used to generate a signal data base (wheel vertical acceleration, wheel vertical speed, dynamic wheel load change).
- This database is necessary for the state detection for the operation of vertical dynamic relevant chassis control systems, in particular semi-active Dämpfkraft horrier mentioned necessary.
- the orientation of the generally on the wheel carrier, the handlebar or the spring-damper strut stationary arranged sensors is not guaranteed due to the movements within the suspension for typical suspension kinematics. That is, there are significant angular deviations of the sensor plane with respect to a perpendicular of the vehicle coordinate system.
- This measured acceleration error component represents a function of the positional deviation (angle-plane error) and of the effective horizontal acceleration vector.
- the horizon refers to a road-safe coordinate system.
- the problem with this acceleration error component is that the signal drift of a target signal (vertical velocity) obtained by numerical integration from the acceleration signal is difficult to avoid by conventional filter devices, with significant impairment of the signal validity; the measured acceleration quantity may have significant measurement errors (order of magnitude up to 20%); - certain points for attachment, especially on components that perform pronounced pivoting movements (handlebar, inclined spring-strut), exude for sensor integration in the chassis; on an off-road track, on which in addition to the already large changes in position of the sensor in the chassis still correspondingly large inclination or slope angle occur, a numerical integration of the signal is no longer feasible.
- This cross-sensitivity is particularly position-dependent - in the time-invariant sensor orientation in the real driving operation of a motor vehicle, if no corrective measures are taken, problems in the signal processing.
- the object of the invention is to provide a possibility for angular error correction of an acceleration sensor in the wheel suspension of a vehicle.

- the measuring device comprises both an angle sensor and an acceleration sensor, which is integrated together with the angle sensor in the first joint, the angle sensor and the acceleration sensor are arranged in close spatial proximity to each other. Since it is possible to determine the deflection of the first joint with the aid of the angle sensor and from this the position of the joint relative to the structure can be determined, it is also possible to determine the inclination of the acceleration sensor relative to the standard position. The angle error can therefore be corrected by means of the angle sensor.
- the spatial summary of the acceleration sensor with the angle sensor has the additional advantage that only one harness for both sensors must be laid. Furthermore, measures must be taken to integrate the sensors into suspension components and to protect against environmental influences, such as e.g. Splash etc. only once. Finally, the common use of an evaluation device is possible, which is preferably integrated together with the measuring device in the joint.
- the angle sensor is used for compensation or correction of the angular error of the acceleration sensor, in particular of values or signals determined by means of the acceleration sensor.
- the angle sensor can also be used for other purposes.
- the angle sensor can detect a deflection of the joint in two or at least two different planes, which are preferably aligned perpendicular to each other.
- the acceleration sensor may accelerations in three or at least three capture different spatial directions.
- the angle sensor and the acceleration sensor are arranged on the same board.
- the first joint is a ball joint or a rubber-metal joint.
- the wheel carrier is connected by means of the first joint with the coupling member.
- the coupling member may be a tie rod.
- the coupling member is a Rad enclosureslenker, in particular a wishbone or trailing arm.
- the first joint preferably has a housing and an inner joint part arranged in the housing, which is movable relative to the housing, wherein the measuring device (sensor arrangement) is arranged in particular in or on the housing.
- the angle sensor has a magnet attached to the inner part and at least one magnetic field-sensitive sensor mounted in or on the housing.
- the magnetic field-sensitive sensor may be attached to the inner part and the magnet to the housing.
- the inner part is preferably a ball pin, which has a ball joint and is rotatably and / or pivotally mounted in the housing by means of this, so that the first joint forms a ball joint.
- the invention further relates to the use of an angle sensor for correcting the angular error of values or signals determined by means of an acceleration sensor, wherein the sensors are or are integrated together in a joint of a wheel suspension of a vehicle, in particular a motor vehicle.
- the wheel suspension is, in particular, a wheel suspension according to the invention, which can be developed according to all embodiments described in this connection.
- the invention relates to a method for compensating or correcting angular errors of values or signals determined by means of an acceleration sensor, wherein the acceleration sensor is integrated together with an angle sensor in a joint of a wheel suspension, at least one deflection of the joint with the angle sensor is measured, at least one value or signal is measured by means of the acceleration sensor and the measured value or the measured signal taking into account the measured deflection is corrected.
- the wheel suspension is, in particular, a wheel suspension according to the invention, which can be developed according to all embodiments described in this connection.
- the value or signal determined by means of the acceleration sensor or in particular is an acceleration or an acceleration signal.
- a method for signal offset correction (angular error correction) of an environment characterized by significant changes in position is thus implemented
- Acceleration sensor proposed by means of the so-called sensor integration.
- the basis for this is mounted on the ball joint or on the rubber-metal joint of a suspension and an angle sensor comprehensive measuring device, which also includes a t ⁇ axialen acceleration sensor.
- the relative swivel angle of the joint in two axes and the accelerations of the sensor unit along three axes are measured.
- the vertical acceleration is to be measured by the wheel-side ball joint or by the wheel carrier by means of the acceleration sensor.
- the arrangement possibilities of the sensor are no longer restricted by the acceleration sensor, that is to say that, for example, the highly integrated sensor can also be applied to very short arms ( ⁇ 0.2 m).
- the vehicle bus system on which usually the horizontal acceleration variables are sent, is not burdened by other "consumers”.
- ECU electronic control unit.

- Fig. 2 is a sectional view of the ball joint 7 can be seen which has a housing 13 in which a ball pin 14 is rotatably and pivotally mounted.
- the housing 13 is fixed to the lower Wishbone 3 is connected, whereas the ball pin 14 is fixed to the wheel carrier 2, not shown in Fig. 2.
- the ball pin 14 comprises a joint ball 15 in which a permanent magnet 16 is arranged, whose magnetic field 17 interacts with magnetic-field-sensitive sensors 18 which are seated on a board 19 fastened to the housing 13.
- the magnet 16 and the magnetic field-sensitive sensors 18 together form an angle sensor, by means of which a deflection of the ball pin 14 relative to the housing 13 can be detected.
- the deflection is defined, for example, as an angle between the longitudinal axis 20 of the housing 13 and the longitudinal axis 21 of the ball stud 14. In this case fall in the non-deflected state of the ball joint 7, the two longitudinal axes 20 and 21 together.
