METHOD AND SYSTEM FOR STABILITY CONTROL

摘要

A method for stability control may include receiving vehicle characteristics of a vehicle of a vehicle-trailer system, trailer characteristics of a trailer of the vehicle-trailer system, or steering inputs for the vehicle. The method may include determining a prediction based on yaw rate deviation for the vehicle determined from the vehicle characteristics, trailer characteristics, or steering inputs or hitch rate oscillation of a hitch coupling the vehicle to the trailer determined from the vehicle characteristics, trailer characteristics, or steering inputs, where the prediction may be indicative of a likelihood of instability for the vehicle-trailer system. The method may include generating control actions based on the prediction and hitch rate feedback from the hitch of the vehicle-trailer system or lateral hitch force feedback.

1. A system for stability control, comprising:
a sensor component receiving one or more vehicle characteristics of a vehicle of a vehicle-trailer system, one or more trailer characteristics of a trailer of the vehicle-trailer system, or one or more steering inputs for the vehicle; a predictive component determining a prediction based on:
yaw rate deviation for the vehicle determined from one or more of the vehicle characteristics, one or more of the trailer characteristics, or one or more of the steering inputs; orhitch rate oscillation of a hitch coupling the vehicle to the trailer determined from one or more of the vehicle characteristics, one or more of the trailer characteristics, or one or more of the steering inputs,the prediction indicative of a likelihood of instability for the vehicle-trailer system; and a control component generating one or more control actions based on the prediction and:
hitch rate feedback, wherein the sensor component calculates a hitch rate of the hitch of the vehicle-trailer system; orlateral hitch force feedback from the sensor component, wherein the sensor component, the predictive component, or the control component is implemented via a processing unit.
