Embodiment Construction

[0022] In the following drawings, the same reference numerals are used to designate the same parts. The various terms and values ​​are set forth by way of example and are not meant to be limiting.

[0023] The present invention may be incorporated into a vehicle control system including a yaw stability control (YSC) system, a roll stability control (RSC) system, a lateral stability control (LSC) system, an integrated stability control (ISC) system, or a vehicle control system Use to achieve desired vehicle performance. The invention is also illustrated using an Integrated Sensing System (ISS), which uses centralized motion sensors like an Inertial Measurement Unit (IMU) and other available units, but in addition to decentralized sensors. Although primarily a centralized motion sensor, such as an IMU, is illustrated, the techniques illustrated here can be easily transformed to use other discrete sensors.

[0024] Referring to FIG. 1 , there is shown a block diagram of a contr...

Abstract

A system and method of controlling a vehicle with a trailer comprises determining the presence of a trailer, generating an oscillation signal indicative of trailer swaying relative to the vehicle, generating an initial weighted dynamic control signal for a vehicle dynamic control system in response to the oscillation signal, operating at least one vehicle dynamic system according to the dynamic control signal, and thereafter, iteratively generating a penalty function for the weighted dynamic control signal as a function of the oscillation signal response. A neural network with an associated trainer modifies the dynamic control signal as a function of trailer sway response.

Description

technical field [0001] The present invention relates generally to dynamic control systems for motor vehicles and trailers, and more particularly to systems for reducing trailer-to-vehicle roll through the use of neural network control methods. Background technique [0002] Trailer rocking can create vehicle stability issues. This occurs under certain conditions where the vehicle is towing a trailer, where the trailer's towing point is rearward across the axle, such as when a light vehicle is towing a trailer using a hitch or trailer equipment. Trailer roll is a condition in which the pivot between the trailer and towing vehicle rocks from side to side and / or up and down in an oscillating fashion. This situation occurs when the vehicle is difficult to maneuver, especially under heavy braking and when driving down hills. Trailer rocking can lift the rear end of the vehicle and drag the vehicle side to side, significantly increasing the risk of a rollover accident. [0003] ...
