Definitions
- the invention relates to a method and a device for stabilizing a trailer combination and a control unit for performing the method according to the preambles of the independent claims.
- a trailer combination consists of a towing vehicle in the form of a conventional two-axle motor vehicle with a towing coupling which is attached to the motor vehicle, a trailer with its coupling being coupled to the towing coupling.
- a ball is provided at the end of the towing coupling and the coupling of the trailer engages around this ball in a rotatable and pivotable manner.
- the towing vehicle and trailer When driving straight ahead, the towing vehicle and trailer have a common longitudinal axis.
- the trailer coupling rotates around the vertical axis of the ball of the towing coupling of the towing vehicle, so that the longitudinal axes of the towing vehicle and trailer are at an angle, also known as the articulation angle, to one another.
- the lateral force initially decreases on the rear axle and increases on the front axle.
- the vehicle tends to turn into the curve. rotate.
- the radius of the orbit becomes smaller and it tries to set a new balance. This is done by increasing the yaw rate and the slip angle. In extreme cases, there is no new equilibrium, the vehicle begins to swing or even skid.
- a method for stabilizing a trailer combination is specified.
- the trailer spann consists of a towing vehicle, that is, the motor vehicle with a towing coupling which is arranged at the rear of the towing vehicle.
- the trailer combination also has a trailer which is articulated to the towing coupling of the towing vehicle via a coupling arranged at the front end of the trailer.
- the towing coupling and the trailer coupling have a common pivot point, which lies in the vertical axis of the ball of the towing coupling.
- the invention is characterized in that when cornering is braked on the wheels of the rear axle, a steering angle that is the same as the wheels of the front axle of the towing vehicle is set in order to stabilize the trailer combination. If the towing vehicle is decelerated, a braking effect occurs. This can be triggered by the driver pressing the brake on the towing vehicle.
- the object is achieved in that with a trailer combination which is braked when cornering, the towing vehicle on the rear axle makes a steering angle in the same direction as the front axle or at least no steering angle in the opposite direction.
- the steering angle in the same direction is thus also carried out, in particular, in a low speed range in which the rear axle steering usually has an opposing steering angle. blow would perform.
- steering is therefore carried out in the opposite direction in order to make the vehicle more agile (vehicle becomes more agile).
- a minimized turning maneuver with rear axle steering can be carried out if the rear wheels are steered in the opposite direction to the maximum. In other words, this minimizes the turning radius of the vehicle.
- the opposite steering angle leads to an increase in the yaw moment of the vehicle. This in turn would lead to a further destabilization of the journey of the trailer combination when cornering with the brakes, in particular with an unbraked or overrun-braked trailer.
- the steering angle on the rear axle is in the same direction, however, the yaw moment of the vehicle is reduced and the trailer combination is stabilized. This is due to the fact that when the steering movement is carried out in the same direction on the rear axle and on the front axle, the instantaneous pole of the towing vehicle is located behind the rear axle. This has the positive consequence that a stabilizing effect is produced or maintained.
- the method can be designed in such a way that when the commercially available unbraked trailer is connected to the control of the rear axle steering, which is preferably designed as steer-by-wire steering, this trailer operation is signaled. In this way, steering in the same direction on the rear axle can be set up independently of the current speed, i.e. even when driving slowly.
- the driver of the towing vehicle can choose between the operating modes of minimal turning radius and braking cornering, for example in the cockpit.
- the rear axle steering of the towing vehicle is preferably designed as steer-by-wire steering.
- the steering handle that is to say the steering wheel of the vehicle which actuates the front axle steering by means of the driver.
- the rear axle steering causes a change in the wheel steering angle on the rear axle. This change will depend on the at the Front axle set wheel steering angles and other parameters, such as the vehicle acceleration, the vehicle speed and the existing yaw rate of the vehicle and other parameters.
- the yaw moment of the towing vehicle is monitored during trailer operation at least at intervals in order to make at least one steering angle on the rear axle in the same direction as the front axle when an instability of the trailer combination is detected.
- Vehicles today are usually equipped with a so-called ESP.
- This is a so-called electronic stability program, which, among other things, records the yaw rate of the vehicle around its vertical axis by means of suitable sensors. The yaw rate or yaw moment on the towing vehicle can thus be determined. If this yaw rate or the yaw moment increases when cornering is braked, it is obvious that destabilization of cornering of the trailer chassis is imminent or already taking place.
- the required wheel steering angle on the rear axle can be set in the sense of a steering angle in the same direction by a suitable control unit.
- Braked cornering is preferably determined by evaluating acceleration sensors present in the vehicle and / or by means for detecting a braking process of at least one wheel of the towing vehicle and / or the trailer.
- Suitable acceleration sensors are available, for example, in control units such as the ESP control unit. Such sensors can also be installed in the chassis of the vehicle.
- the means mentioned for detecting a braking process can, for. B. be sensors on the pedals, so that the will or the actual braking can be sensed by the vehicle driver.
- sensors can be present on the brake actuators.
- the characteristics of the towing vehicle during braking can be stored in a suitable control device. In trailer operation, coupling with the trailer indicates to the control unit that the clamping operation is present.
- the inertia of a trailer causes a change in the braking curve. As mentioned above, this is also dependent on the loading stood the trailer. It is obvious that accelerations differing from the normal state of the towing vehicle are present and can be sensed in trailer operation, ie when the trailer is connected.
- the wheel steering angle on the front axle is advantageously increased by the superimposed steering, so that the turning radius is reduced to a maximum.
- the steering angle on the rear axle can be changed in such a way that, although the steering angle is still in the same direction on the front and rear axles, the turning radius is further minimized. The stabilizing effect thus remains.
- the method can also be used with a trailer combination driving downhill.
- This is also possible with unbraked cornering. This is due to the fact that when cornering downhill due to the inclined plane a sliding effect of the trailer is generated due to gravity. This is equivalent to the effect when cornering is braked on a level road and the trailer is unbraked or only up. pushes in the direction of the towing vehicle with running brakes.
- the advantages of the stabilizing effect of the process can also be used when the trailer is cornering downhill.
- the method when a parking process is detected, the method is interrupted until the parking is ended, so that steering angles in opposite directions are permitted on the front and rear axles.
- Maximum agility is beneficial when parking.
- a vehicle can be parked more efficiently by using the maximum possible steering angle on the front and rear axles and the minimum or smallest possible turning circle by steering in opposite directions.
- the invention relates to a control device for a towing vehicle for carrying out the method according to one of the preceding claims.
- a control unit can be present in a motor vehicle separately and exclusively for stabilizing the Gespannbe operation.
- the method can also be carried out on a control device present in the vehicle, preferably on an ESP control device.
- an existing ESP control unit and a separate control unit can share sub-functions or complement one another to execute the method.
- the aforementioned control unit or the aforementioned control units can be connected to sensors so that, depending on the sensor parameters read out by the control unit, braked cornering and / or unbraked or braked downhill travel can be recognized.
- the sensors are preferably connected to the control unit by means of a vehicle bus system. It is preferably a CAN bus system.
- the sensors are preferably designed on the wheels of the towing vehicle to evaluate the wheel steering angle and / or in the towing vehicle to evaluate its speed and / or to evaluate the yawing moment of the towing vehicle and / or to evaluate the braking process on the towing vehicle and / or the trailer.
- sensors can be present on the Switzerlandfahr that detect the pendulum movement of the trailer. This can be made possible, for example, by means of optical sensors at the rear of the towing vehicle will.
- the movement of the clutch with respect to the clutch ball can be sensed, in particular by means of a contactless, preferably inductive sensing.
- the invention relates to a device for stabilizing a trailer combination.
- This device is preferably part of the towing vehicle and can be used with a trailer combination consisting of a towing vehicle and a trailer, at least the towing vehicle being steerable on its front and rear axles and having at least one control unit, as mentioned above.
- the device is characterized in that, when cornering and / or driving downhill, the wheels of the towing vehicle on the rear axle and the wheels on the front axle can be adjusted to a more sensible steering angle in order to stabilize the trailer combination.
- the stabilizing steering angle on the rear axle is carried out as mentioned above as a function of the parameters evaluated by the control unit.
- the invention is intended in particular to enable conventional unbraked or only overrun-braked trailers to be used.
- trailers with active braking devices or steering on the wheels can also be operated with this method.
- Even actively braked or steered trailers can be improperly loaded, which can quickly lead to destabilization when cornering with brakes.
- the active actuators on the trailer, for. B. fail due to an electrical defect, so that the actually actively driven trailer behaves like a conventional unbraked trailer in the event of a failure.
- the stabilizing steering angle in the same direction on the rear axle can be set as a function of the parameters evaluated by the control unit, so that the stabilizing steering angle takes into account the actual driving state of the combination.
- the steering is preferably designed as steer-by-wire steering both on the front axle and on the rear axle.
- Must, as already mentioned, on the front axle If a larger steering angle is set than is intended by the driver of the vehicle, a corresponding control unit on the front axle can set a higher required steering angle.
- Overlay steering can therefore be dispensed with on the front axle, which brings cost advantages. With such a device, the stabilization of a trailer combination can be carried out to advantage.
- Figure 1 shows a plan view of a trailer combination
- the single figure shows a schematic plan view of a towing vehicle 1 and a trailer 20.
- the towing vehicle 1 has a front axle with wheels 2 and 3.
- a rear axle with wheels 4 and 5 is also shown.
- a towing coupling 8 is attached to the rear of the vehicle.
- a coupling ball 9 is arranged at the end of the towing coupling 8.
- the trailer 20 has a trailer axle with wheels 26 and 27. At the front of the trailer, a trailer hitch 28 is arranged.
- Trailer 20 is coupled to the towing vehicle 1 in that the coupling 28 is rotatably fixed on the coupling ball 9 of the towing coupling 8 in the usual manner.
- the aborted angle a shows the combination angle, also called the kink angle.
- the trailer combination 30 is in a braked cornering.
- a wheel steering angle 6 v to the left is set on the front wheels 2 and 3.
- a wheel steering angle 6h is set in the same direction to the left.
- the foot brake is decelerated by means of a force and a braked cornering movement is initiated or carried out. Due to the deceleration of the towing vehicle 1 due to the braking process, the trailer 20 pushes towards the rear of the towing vehicle, the force denoted by Fn-äg acting on the common pivot point on the coupling ball. This changes the yaw moment of the towing vehicle MGier its vertical axis increased.
- the trailer combination 30 is stabilized by the steering angle shown in the same direction on the rear axle on the towing vehicle. The towing vehicle or the trailer does not break away, but the intended trajectory of the left-hand bend can be retained.
- the invention relates not only to passenger vehicles, but is also suitable for trailer combinations in the commercial vehicle sector. Trailers with multiple axles can also be used.
