Method for assisting the driver of a motor vehicle with a fishtailing trailer
First Claim
1. A method for assisting a driver of a motor vehicle with a trailer that is fishtailing, comprising:
- detecting a fishtailing of the trailer by analyzing at least one driving state variable;
outputting a warning to the driver upon detection of a critical fishtailing so as to induce the driver to brake;
monitoring a brake actuation implemented by the driver; and
assisting the driver in a braking operation by automatically actuating a vehicle brake, a brake pressure being exerted by which a vehicle deceleration is achieved for the purpose of stabilizing the trailer, wherein the assisting is conditioned upon the driver braking in response to the warning.

Abstract
The present invention relates to a method for assisting the driver of a motor vehicle with a fishtailing trailer. A vehicle with a fishtailing trailer can be stabilized in an especially rapid manner in that, in a first state, the fishtailing of the trailer is analyzed by evaluating at least one vehicle state variable, and when critical fishtailing is detected, a warning is output to the driver in a second state so as to induce the driver to brake, and the driver—provided he initiates braking—is assisted in the braking operation by automatic actuation of the vehicle brakes, a brake pressure being set at which the most optimal vehicle deceleration possible is achieved.

8. A device for assisting a driver of a motor vehicle with a trailer that is fishtailing, comprising:
-
a first sensor system for detecting the trailer fishtailing; a control device for analyzing at least one item of sensor information for the purpose of situation detection; a device for outputting a warning to the driver upon detection of a critical fishtailing so as to induce the driver to brake; a second sensor system for monitoring a brake actuation implemented by the driver; and an electrically triggerable brake system that is automatically actuated by the control device in such a way that a vehicle deceleration is achieved for the purpose of stabilizing the trailer, wherein the actuating by the control device is conditioned upon the driver braking in response to the warning. - View Dependent Claims (9, 10, 11, 12)
