Detection of and counter-measures for jackknife enabling conditions during trailer backup assist
First Claim
1. A method for preventing a jackknife condition between a vehicle having a data processing device and a trailer towed by the vehicle, comprising the steps of:
- assessing jackknife information and a jackknife condition threshold during backing of the trailer to detect an imminent jackknife condition; and
implementing a jackknife counter-measure in response to detecting the imminent jackknife condition during backing of the trailer by the vehicle, implementing the jackknife counter-measure includes at least one of reducing a speed of the vehicle, increasing a radius of a curvature of a path of the trailer, and inhibiting a decrease in the radius of the curvature of the path of the trailer.

Abstract
A vehicle comprises a trailer angle detection apparatus and a trailer backup control system coupled to the trailer angle detection apparatus. The trailer angle detection apparatus is configured for outputting a signal generated as a function of an angle between the vehicle and a trailer towably attached to the vehicle. The trailer backup control system includes a jackknife enabling condition detector and a jackknife counter-measures controller. The jackknife counter-measures controller alters a setting of at least one vehicle operating parameter for alleviating an adverse jackknife condition during backing of the trailer by the vehicle when the jackknife enabling condition detector determines that a jackknife enabling condition has been attained at a particular point in time during backing of the trailer by the vehicle.

6. A trailer backup control system for a vehicle capable of towing a trailer, comprising:
-
a trailer angle detection apparatus configured for generating a signal as a function of an angle between the vehicle and the trailer; a jackknife condition detector; and a jackknife counter-measure controller configured for altering at least one vehicle operating parameter when a jackknife condition is imminent during backing of the trailer by the vehicle, altering at least one vehicle operating parameters includes at least one of reducing a speed of the vehicle, increasing a radius of a curvature of a path of the trailer, and inhibiting a decrease in the radius of the curvature of the path of the trailer. - View Dependent Claims (7, 8, 9)
