Definitions
- the invention relates to a sensor device for determining a steering angle in a motor vehicle.
- the invention also relates to a corresponding method.
- optical or magnetoresistive steering angle sensors are used, which serve to detect the driving direction desired by the driver.
- sensors are usually based on an optical or magnetoresistive measuring principle.
- the information about the steering angle derived from the output signal of the steering angle sensor is used below as an input variable of different vehicle systems, for example an ABS / ESP system or an electric power steering system.
- DE 100 64 630 A1 discloses a kingpin bearing is disclosed in which in a storage cassette, a rotation angle sensor is integrated, which detects a relative rotation between an inner pot and an outer pot.
- the vehicle sensor is designed as a potentiometer wherein the potentiometer is arranged on a support or on tie rods of a forklift.
- multiturn steering angle sensors can be used. Due to the high cost of multiturn sensor systems, however, steering angle sensors are usually used which can not clearly represent the total possible steering angle range of up to three steering wheel revolutions.
- single-turn steering angle sensors can clearly map only one full revolution, 360 ° or a part thereof, for example 180 °.
- the determination of the absolute steering angle over the total possible steering angle range can be carried out with further physical variables present from the vehicle, such as e.g. the wheel speeds of the individual wheels of the vehicle take place.
- This method has the disadvantage that a certain distance traveled or driving speed is necessary to enable a clear determination of the steering angle.
- the invention is based on the problem of disclosing a device and a method for determining an absolute steering angle information in a motor vehicle.
- the invention is based on the idea to provide additional means for detecting elastokinematischer angle on a steering joint 10 of the steering for determining an absolute steering angle information in a motor vehicle with a arranged in the effective range of a rotatable steering element of a steering 8 steering angle sensor 7.
- an integrated angle sensor for the detection of elastokinematic angle, an integrated angle sensor known from the prior art can be used.
- the integrated angle sensor is arranged in a suitable steering joint of the wheel link of a steerable front or rear axle. It goes without saying that the deflection of the corresponding steering joint must correlate with the deflection of the wheel.
- FIG. 1 shows by way of example the embodiment of an integrated angle sensor 4, 5 as it can be arranged in a ball joint:
- a ball stud 3 consists of a joint ball 1, a pin 2 and the magnetic field transmitter 4 suitably arranged therein.
- a magnetic field detector 5 In magnetic operative connection thereto is a magnetic field detector 5.
- the arrangement shown is capable of relative angular movements of the magnetic field generator 4 and the magnetic field detector 5 to detect the longitudinal axis of the ball stud 3.
- the integrated angle sensor 4,5 instead of a magnetic measuring principle, consisting of magnetic field sensors and magnetoresistive receiver elements and an optical measuring principle, consisting of a corresponding pair of optical sensors and detectors, pursue.
- FIG. 2 shows schematically the structure of a front wheel steering in a vehicle, with steering wheel 6, steering angle sensor 7 and power steering 8.
- the integrated angle sensor on the steering joint 10 which is the head-side angle joint of a tie rod 9, arranged or integrated.
- the method according to the invention provides for the signal of a steering angle sensor 7 to be made plausible with a unique signal range of the integrated angle sensor 4, 5 in order to determine therefrom an unambiguous steering angle information 4, 5.
- FIG. 3 shows an exemplary embodiment of the method according to the invention.
- FIG 3 shows an angle information normalized to the value 1 of a corresponding signal of a steering angle sensor. It can be seen that the angle information of the steering angle sensor is ambiguous over the total possible steering angle range, for example three full steering wheel revolutions.
- the relationship shown in the graph 2b of FIG. 3 shows an angle information normalized to the value 1 of a corresponding signal of an integrated angle sensor system 4, 5. It can be seen that the angle information of the integrated angle sensor 4, 5 is unambiguous over the possible deflection range of the steering joint.
- An exemplary embodiment of the method according to the invention provides to plausibilize a signal that is ambiguous over the total possible steering angle range or an ambiguous angle information of a steering angle sensor 7 with the unambiguous angle information derived from a unique signal of the integrated angle sensor 4.5 in order to obtain clear steering angle information therefrom to determine.
- a further exemplary embodiment, for which no figure is provided provides for a plausibility check of a signal which is unambiguous over the entire possible steering angle range or a unique angle information derived therefrom of a steering angle sensor with the unambiguous angle information derived from a unique signal of the integrated angle sensor system 4, 5 to determine or verify a unique steering angle information.
- the method can also be used in superimposed steering systems, whereby the feed-in angle, which is introduced additively by means of an overlay gearbox, must be taken into account accordingly.
- Another advantage of the invention is that the determination of the absolute steering angle information at vehicle standstill, i. immediately after the start-up phase of an electronic control unit, and without the need for vehicle movement that requires differential measurement of wheel rotation or speed information.
- the problem with regard to the evaluation of such information when driving on ground with low coefficient of friction or spinning wheels thus also eliminated.
- An absolute steering angle information determined by the method according to the invention can be supplied to further electronic vehicle systems in the following.
