- At least one maximum value for the additional assistance torque M ASS (maximum assistance torque M max ) applied to the steering wheel is specified, that the manual torque M H applied by the vehicle driver to the steering wheel is continuously determined, and that the maximum Assistant torque M max is dynamically adapted to the manual torque M H currently applied by the driver to the steering wheel.
- At least one lower limit value (limit torque M H , L o) is specified for the assistance torque additionally applied to the steering wheel, that the manual torque M H applied by the vehicle driver to the steering wheel is continuously determined, and that the Driver torque M H applied to the steering wheel is compensated by an additional compensation steering torque if the determined manual torque M H does not exceed the lower limit value (limit torque M H , LOW ).
- a value in a range from 0.7 Nm to 1.2 Nm is preferably specified as the lower limit value (limit torque M H , LO W) for the additional torque applied to the steering wheel.
- a signal of the hand torque M H applied by the vehicle driver to the steering wheel is filtered, preferably by a low-pass filter of the first (1st) order.
- This filter advantageously has a filter time constant of approximately 10 ms.
- at least one lower limit value (limit torque M H , L ow) is specified for the assistance torque additionally applied to the steering wheel, that the manual torque M H applied by the vehicle driver to the steering wheel is continuously determined, and that a tracking control steering torque , which is necessary for guiding the vehicle in the lane, is at least approximately linearly limited to a maximum value with increasing manual torque M H if the determined manual torque M H exceeds the lower limit value (limit torque M H , L O W).
- At least one upper limit value (limit torque M H , HIGH ) is specified for the assistance torque additionally applied to the steering wheel, that the manual torque M H applied by the vehicle driver to the steering wheel is continuously determined, and that a desired Steering torque, which corresponds to a driver's request for a steering intervention, is set when the determined manual torque.MH exceeds the upper limit value (limit torque M H , HIGH ).
- a value in a range from 1.8 Nm to 2.2 Nm is preferably specified as the upper limit value (limit torque M H , HIGH ) for the assistance torque additionally applied to the steering wheel.
- the manual torque M H applied by the vehicle driver to the steering wheel is continuously determined, that a steering control steering torque, which is necessary for guiding the vehicle in the lane, is adjusted, that at least an upper limit value (limit torque M H , HIGH ) is specified for the additional assistance torque applied to the steering wheel, and that the tracking steering torque is reduced to, preferably, according to a predetermined function, preferably a time-controlled ramp function Value zero.
- a linearly decreasing function with a gradient in a range from 2.5 Nm to 3.0 Nm is preferably specified as the time-controlled ramp function.
- a steering torque control module which is provided in particular for carrying out the method according to the invention and which is characterized in that an additional assistance torque M AS s is applied to a hand steering wheel of the vehicle, by means of which the vehicle driver of the vehicle when driving in a lane is supported.
- the object is also achieved by a vehicle with a vehicle steering system and with a lane guidance system which has a steering torque control module according to the invention.
- FIG. 1 shows a diagram of a hand torque-dependent torque limitation of the additional assistance torque according to the invention.
- a vehicle is equipped with a driver assistance system for "automatic" lane guidance (lane guidance system) equipped of the invention.
- the lane guidance system has a system component for the detection of the driver's request, which recognizes the driver's wish when the "automatic" lane guidance is active and controls the lane guidance system in accordance with this request in such a way that it is complied with in a convenient manner.
- the driver assistance system uses a steering angle setpoint or a steering torque setpoint (assistance torque) to give a steering control system to the driver, depending on the system parameterization, a more or less pronounced steering recommendation.
- a steering angle setpoint or a steering torque setpoint assistant torque
- further steering movements arise due to the feedback of disturbances from the road and from the driver himself.
- the system has to compensate for these disturbances, on the other hand, it must not force the driver against his request because he is driving may have to react to an impending danger or want to change lanes.
- the torque applied by the driver on the steering wheel is observed by a torque sensor. If the driver follows the steering recommendation of the assistance system, the hand torque is approximately zero or at least very small. A deviation of the vehicle driver from the specification of the automatic lane guidance leads to a significant increase in the manual torque, since in this case the vehicle driver works against the assistance system.
- a basic idea of the invention is to detect and interpret the wish of the vehicle driver on the basis of the course of the hand torque and a comfortable mutual To achieve vehicle driver and system takeover by dynamically adapting the maximum specifiable assistance torque M AS s to the manual torque M H applied by the driver.
- FIG. 1 shows a plot of the manual torque curve M H with a lower limit torque M H , O and with an upper limit torque M H , H I G H against the curve of the assist torque M AS s-
- the manual torque remains below a first threshold value (lower limit torque M H , L o) during a journey with active automatic tracking, it is regarded as a malfunction and compensated by the controller of the tracking system (left horizontal straight line I in FIG. 1).
- the assistance torque M ⁇ SS is increased up to an upper limit value M AS s, max.
- at least the upper limit value M ASS , m a ⁇ of the assistance torque M ASS can be dynamically adapted to the manual torque M H currently applied by the driver to the steering wheel. This is shown by the dashed lines IV, V, VI in Fig. 1.
- the signal of the hand torque is processed by suitable filters so that brief peaks in the signal curve, in particular due to the inertia of the steering column and the steering wheel in connection with disturbances from the road (such as potholes), no output signal above M H , OW create.
- Lane guidance system is limited in such a way that the torque required for guiding the vehicle in the lane is linearly limited to a maximum value with increasing manual torque (falling straight line II in FIG. 1).
- the torque that is necessary for guiding the vehicle in the lane is additionally regulated by a time-controlled ramp.
- the compensation value determined and already limited at the time the upper threshold value is reached is adjusted to the value 0 (ZERO).
- ZERO the value 0
- the output value M ASS , max left straight line VII in FIGS. 2 and 3
- the driver again has a "normal" steering feel, so that he, as if by the Known driving without automatic lane guidance, can change lanes or avoid maneuvers. The driver has been taken over.
- the "outer" compensation limitation is opened.
- the initial value for the linear limitation dependent on the manual torque is controlled to a maximum value (horizontal straight line X in FIGS. 2 and 3) via a time-controlled ramp (straight line IX increasing in time in FIGS. 2 and 3).
- Guide variables for a controller of the guidance system are determined beforehand, the initially calculated steering angle corresponding to the steering angle currently set by the vehicle driver. During the time of the system takeover, these command variables are controlled by time ramps to the value 0 (ZERO). If these command variables have become 0 (NULL), the system has been adopted.
- the method can be implemented in parts or combined with known methods. In addition to the described methods, this also includes possible optical or acoustic or other haptic information (such as via the accelerator pedal) for the driver to keep lane.
