Abstract

A drifting training assistance system is provided for a motor vehicle for learning drifting techniques required in high-performance driving training. The steering and the gas pedal movement, or the combined action thereof, is taken on and/or supported by a drifting assistance system.

First claim

What is claimed is:

1. A training system for a motor vehicle for learning a drifting technique required during high-performance driver training, the system comprising:
a drifting assistance system comprising:
sensors for sensing a steering angle, a yaw rate and a lateral acceleration of the motor vehicle; and
a controller configured to control respective positions of a steering wheel and an accelerator pedal of the motor vehicle so as to thereby cause the motor vehicle to automatically execute the drifting technique along a course curvature that is estimated by the controller based on the sensed steering angle, yaw rate and lateral acceleration of the motor vehicle,

wherein the at least one of the steering wheel and accelerator pedal is controlled by the controller to provide resistance feedback to a driver for learning the drifting technique, and
wherein the course curvature is adaptable via a manually applied torque.

2. The training system according to claim 1 , wherein the automatic execution of the drifting technique is continued even if a rear of the motor vehicle breaks out as a result of an acceleration dosed by the driver or by the drifting assistance system.

3. The training system according to claim 1 , wherein the controller determine a side slip angle of a vehicle-fixed reference point as estimated during activation of the drifting assistance system, and controls the estimate side slip angle to a driver-adjustable required value by way of acceleration or deceleration of the motor vehicle.

4. The training system according to claim 1 , wherein actuating variables of a controller of the drifting assistance system are acoustically and/or optically representable to the driver.

5. The training system according to claim 1 , wherein the drifting assistance system is activatable by carrying out a kick down of the accelerator pedal.

6. The training system according to claim 1 , wherein the drifting assistance system is configured to record driving data parameters and to allow an analysis of driven maneuvers based on the recorded driving data parameters.

7. The training system according to claim 6 , wherein the driving data parameters comprise speed, yaw rate, and side slip angle.

8. The training system according to claim 1 , wherein the drifting assistance system is configured to enable, by way of the manually applied torque, a driver to correct the automatic steering movements.

9. A training method for a driving maneuver of a motor vehicle, the method comprising:
activating a drifting assistance system, comprising sensors for sensing a steering angle, a yaw rate and a lateral acceleration of the motor vehicle, and a controller configured to control respective positions of a steering wheel and an accelerator pedal of the motor vehicle;
determining a course curvature, via the controller, based on the sensed steering angle, yaw rate and lateral acceleration of the motor vehicle;
controlling the steering wheel and accelerator pedal positions, via the controller, so as to thereby cause the motor vehicle to automatically execute the drifting technique along a course curvature such that resistance feedback for learning the drifting technique is provided to the driver by at least one of the steering wheel and the accelerator pedal; and
adapting the course curvature via a manually applied torque.

10. The method according to claim 9 , wherein the automatic execution of the drifting technique is continued even if the rear of the motor vehicle breaks out as a result of an acceleration burst by the driver or by the drifting assistance system.

11. The method according to claim 9 , wherein activating the drifting assistance systems further includes the acts of:
determining a side slip angle of a vehicle-fixed reference point as estimated during the activation; and
controlling the estimated side slip angle to a driver-adjustable required value by way of acceleration or deceleration of the vehicle.

12. The method according to claim 9 , further comprising the act of:
outputting acoustically and/or optically actuating variables of the drifting assistance system.

13. The method according to claim 9 , correcting, by way of the manually applied torque, the automatic steering movements.
