Abstract
A driver assistance system for a vehicle includes a steering assistance system for autonomously generating steering commands, a first actuating drive for adjusting a steering angle on a steerable wheel of the vehicle corresponding to the steering commands and a steering wheel that is rotatable coupled to the steering angle by a second actuating drive. The steering assistance system actuates the second actuating drive in order to favor a low-frequency component of a frequency spectrum of changes of the steering angle in the rotation of the steering wheel than a high-frequency component of the frequency spectrum.
Claims16
A driver assistance system for a vehicle having a steerable wheel comprising:
- a steering assistance system configured to calculate a set point value of a steering angle for the steerable wheel and to generate a steering command based on the set point value, wherein the steering command includes a low-frequency component associated with a path of the vehicle and a high-frequency component associated with a lane position of the vehicle;
- a first actuating drive configured to receive a first control signal from the steering assistance system and to adjust the steering angle on the steerable wheel of the vehicle corresponding to the low-frequency component and the high-frequency component of the steering command;
- a steering wheel rotatably coupled to the steerable wheel;
- and
- a second actuating drive configured to receive a second control signal from the steering assistance system and to rotate the steering wheel based the second control signal for reproducing the low-frequency component of the steering command and reducing the high-frequency component of the steering command to eliminate a shaking movement of the steering wheel.
