Definitions
- the invention relates to a tilt control device for a vehicle, with detection means for detecting a roll speed signal representing the roll speed of the vehicle and for detecting a target steering angle signal, with control means for generating a steering signal on the basis of the roll speed signal and the target steering angle signal, and with output means for outputting the steering signal to a steering actuator Steering one or more wheels of at least one axle of the vehicle.
- the invention further relates to a vehicle, in particular a multi-lane vehicle, with such an inclination control device and to a method which functions in the manner of the inclination control device.
- Such an inclination control device is known for example from German published patent application DE 40 32 317 AI.
- the tilt control described there dampens the roll movements of vehicles with four-wheel steering and vehicles with front steering.
- the known inclination control device is based on the roll dynamics of the vehicle body, taking into account signals, which directly or indirectly present the roll angular velocity.
- the driver's desired direction of travel i.e. the target steering angle, is taken into account.
- Improved stability behavior is achieved by additional steering according to German published patent application DE 33 00 640 AI, in which, among other things, the driving speed, the yaw angle speed, the lateral acceleration, the longitudinal acceleration, the steering wheel rotation angle, that is, the desired steering angle, tire conditions or the like are taken into account.
- the rolling behavior of the vehicle is not taken into account.
- control device In the control device according to WO 99/01320 there are two independent partial control devices which intervene in the steering of a vehicle and / or in the chassis actuators of the vehicle.
- the control device is based, for example, on wheel speed signals, yaw rate signals, lateral acceleration signals and steering angle signals.
- a vehicle steering system according to German laid-open specification DE 44 22 031 offers improved emergency running behavior in the event of failure of, for example, a lateral acceleration sensor or a yaw rate sensor. In such a situation of damage, a supporting steering torque is reduced, so that the operability of the steering system remains as optimal as possible even in the event of damage.
- the devices known from the prior art aim to drive a motor vehicle, in specific cases automobiles, in stable driving operation on four wheels. to keep that.
- single-track vehicles for example motorcycles or the like
- multi-lane vehicles can also tip over, so that they can be operated at least temporarily in a single-lane driving mode.
- Such operating states are known, for example, from films and artistic performances.
- This object is achieved in the case of the inclination control device of the type mentioned at the outset in that it controls the steering actuator with the steering signal in such a way that the vehicle is at least temporarily kept in a single-track driving mode.
- the steering signal generated by the inclination control device ensures stable single-track driving operation of the vehicle, which behaves as if a fictitious third wheel were present. Any incorrect steering interventions by the driver are corrected by the inclination control device. Even a multi-lane vehicle that accidentally gets on two wheels can at least temporarily be kept in a single-lane driving mode and thus be stabilized again before it is expediently subsequently operated again in a multi-lane driving mode.
- the inclination control device can be a separate structural unit or, for example, in a driving stability Control of the vehicle can be integrated. It can be implemented in hardware and / or software, for example it can contain program code that can be executed by a control means, for example a microprocessor.
- the control means expediently control the steering actuator in a second direction opposite to the first direction in the event of a change in direction of the vehicle in a first direction predetermined by the target steering angle signal, insofar as this is necessary for control purposes.
- a change in direction is initially initiated by a counter-steering movement.
- the inclination control device then changes the direction of the target steering angle and turns more than specified by the target steering angle.
- the steering signal converges in the direction of the target steering angle signal to a stationary target value.
- Detection means are expediently designed to detect one or more of the signals mentioned below.
- control means advantageously evaluate these signals when the steering signal is formed:
- a yaw rate signal representing the yaw rate of the vehicle
- a lateral acceleration signal representing the lateral acceleration of the vehicle
- transverse speed signal representing the transverse speed of the vehicle, and / or
- a float angle signal representing the float angle of the vehicle.
- a particularly advantageous control concept of the inclination control device according to the invention is based on a model approach in which the behavior of the vehicle can be described with six state variables which are combined to form a state vector z ⁇ .
- ⁇ are the yaw (angle) speed, v the transverse speed,; c the roll angle, k the roll speed, F q v and F q h tire lateral forces on the front wheel and rear wheel of the vehicle, which can be determined from the aforementioned variables.
- ⁇ are the yaw (angle) speed, v the transverse speed,; c the roll angle, k the roll speed, F q v and F q h tire lateral forces on the front wheel and rear wheel of the vehicle, which can be determined from the aforementioned variables.
- ⁇ L is the steering angle set on the vehicle (the index ⁇ L 'always refers to the steering of the vehicle below) and F s is a lateral force acting on the vehicle.
- ⁇ L is the steering angle set on the vehicle (the index ⁇ L 'always refers to the steering of the vehicle below)
- F s is a lateral force acting on the vehicle.
- h w is the height of the kinematic roll pole and lw the center of gravity distance of the kinematic roll pole in the longitudinal direction.
- the feedback parameters in the stabilization vector k must now be determined in such a way that a stable operating state is always reached in a finite time.
- the eigenvalues of the closed control loop (7) are decisive for this. Its system matrix A * results in:
- the non-linearities of the overall system are preferably taken into account in that a suitable stabilization configuration is determined not only for the operating point B, but also for the largest possible environment around B.
- each segment is segmented into 3-6 vehicle speed-specific solutions and, if necessary, into 3-6 longitudinal acceleration-optimized solutions, between which it is possible to switch or interpolate.
- a non-linear controller design can of course also be carried out directly on the basis of the model and synthesis concept presented.
- the control means are expediently designed to generate a steering feedback signal and the output means for outputting this signal to a steering feedback actuator, with which a steering feedback torque for the driver of the vehicle can be generated on a steering handle of the vehicle, for example on a steering wheel or on a steering fork. The driver thus receives feedback on his steering specifications.
- the following expedient embodiments of the invention relate in particular to a multi-lane vehicle which is temporarily kept in a single-lane driving mode by the inclination control according to the invention.
- Multi-lane vehicles are usually operated as permanently as possible so that all wheels are in contact with the road.
- the inclination control device according to the invention expediently determines a tilting condition required for stabilizing the vehicle, in which the vehicle is in the single-track vehicle driving mode. In this tipping state or in the single-track driving mode, the vehicle is operated until it is stabilized. For example, a change of direction is carried out in the single-lane driving mode. Only after the change of direction is the vehicle brought back into a driving state such that all of its wheels are in contact with the road.
- the control means expediently keep the multi-lane vehicle in the tilted state until after an end of tip signal has been determined.
- the end of tipping signal can by the Tilt control device itself can be determined.
- vehicle dynamics control it is also possible for vehicle dynamics control to send a corresponding end of tilt signal to the inclination control device according to the invention.
- the control means expediently contain a status observer.
- sensors are expediently provided for generating the roll speed signal and for determining the setpoint angle signal and, if appropriate, for further of the aforementioned signals.
- the vehicle also contains a steering actuator that can be controlled by the inclination control device.
- a steering reaction actuator for generating a steering reaction signal is advantageously also present in the vehicle according to the invention.
- a steering handle on which the desired steering angle signal is determined, expediently acts only on the steering wheel or wheels of the vehicle via the steering actuator or actuators. It goes without saying that the inclination control device according to the invention can also be designed for multi-axle steering.
- 1 shows a partially highly schematized vehicle according to the invention with an inclination control device according to the invention
- 2 shows a schematically illustrated single-track vehicle according to the invention
- a vehicle 10 shown in Figures 1 and 2 e.g. a motorcycle or an automobile has one or more steerable wheels 11, for example front wheels, as well as non-steerable wheels 12 driven by a motor 13, which are, for example, the rear wheel or wheels of the vehicle 10.
- the wheels 11 can be steered by means of a steering wheel 14, a steering rod or another steering handle.
- the steering intervention does not take place directly, but rather by means of a steering actuator 15, which is controlled by an inclination control device 16.
- An actuation of the steering wheel 14 of the vehicle 10 detects a steering angle sensor 18.
- the steering angle sensor 18 reports a target steering angle signal ⁇ L S0 L to the device 16.
- An input 19 of detection means 20 of the device 16 detects the target steering angle signal £ S0LL and transmits it to a control module 21.
- Driving state sensors 22 to 26 transmit the detection means 20, which are, for example, NEN or more interface modules for detecting digital and / or analog signals, a (longitudinal) speed signal V, a transverse speed signal Vq, a yaw rate signal ⁇ , a roll angle signal K and a roll speed signal K.
- These signals and a reset torque signal M R detected by a tire reset torque sensor 27, which is present at an input 28 of the detection means 20, are transmitted to a driving condition observer 29.
- the driving state observer 29 determines a stationary operating point g B and a state vector Z, for example in accordance with the formulas (1) and (3) mentioned above.
- the driving position observer 29 transmits the stationary operating point g B to the control module 21.
- the control module 21 determines a stationary state Z B of the state vector Z according to, for example, the formula (3), and transmits this to a control module 30.
- the control module 30 calculates the stabilization component K (Z-Z B ), for example according to the formula (6), using the state vectors Z and Z B.
- This stabilization component is added to the default component ⁇ L S0L , so that overall the steering signal ⁇ L (see formula (6)) is formed.
- the steering signal ⁇ L is output by output means 31, which can output digital and / or analog voltage signals, for example, to the steering actuator 15, which controls the steering wheel (s) 11 according to the steering signal ⁇ L.
- a driver of vehicle 10 receives feedback about his operating actions by means of a steering feedback actuator 32, for example a servo motor, which acts on the steering wheel 14.
- a driver steering torque control 34 controls the steering reaction actuator 32 by means of a steering reaction signal M F.
- the input variables of the steering torque control 34 are the target steering angle ⁇ L SOh , the steering signal ⁇ L and the state vector Z.
- the device 16 is preferably designed as a microprocessor control, in which, for example, the modules 21, 29, 30 and 32 are designed as software, for example in the form of software functions or program modules.
- the program code of the program modules is executed by a microprocessor, not shown in the figure, and is stored, for example, in a storage means, e.g. a flash device.
- a change of direction is initiated on the steering wheel 14, the target steering angle signal ⁇ L S0LL shown in broken lines increasing until it reaches a stationary value at a point in time t2.
- the device 16 generates the dotted steering signal ⁇ L , which, following the time tl, initially has a profile opposite to the target steering angle ⁇ L SOh , then rises faster than the specified profile ⁇ L SOLL and after an overshoot that begins at time t2 swings in the stationary target value, which corresponds to the signal ⁇ , SO ⁇ .
- the on steering between times t1 and t2 results in a positive transverse speed V q from the rolling movement of vehicle 10.
- FIG. 4 contains the signals shown in FIG. 3 and additionally the yaw rate and the roll angle profile of the vehicle 10 when changing direction according to FIG. 3. However, the scaling has been changed in comparison to FIG. 3 so that the relation of the roll angle K (drawn in a solid line) increases the steering angle signals ⁇ 5 L and ⁇ L S0LL is correctly displayed. All angle signals are given in degrees, for example. It can be seen from FIG. 4 that device 16 achieves a target roll angle ⁇ z ⁇ e ⁇ of, for example, 20 degrees within a short time of, for example, half a second. The stabilization model of the device 16 is thus suitable for driving maneuvers up to limit areas.
