Embodiment Construction

[0024] refer to figure 1 , represents a block diagram of a control system 10 for a vehicle 14 according to an embodiment of the present invention. In this example, a vehicle 14 includes a vehicle stability control system 12 . Control system 10 monitors and mitigates roll or sway of vehicle 14 and trailer 15 via stability control system 12 and trailer sway control system 16 to provide operating stability. Stability control system 12 may be or include an RSC system, an ESC system, a YSC system, or some other stability control system known in the art. Stability control system 12 and trailer sway controller 16 may be part of vehicle controller 26 .

[0025] IMU data related to the stability control system 12 may indicate trailer sway or roll. But trailer shake is not always communicated to the vehicle in a way that can be detected by the vehicle's IMU sensor set. Also, not all vehicles have an IMU. However, the vehicle IMU will detect stability events about the vehicle, whic...

Abstract

A system and method of controlling a vehicle 14 with a trailer 15 comprises determining the presence of a trailer 15, generating an oscillation signal indicative of trailer swaying relative to the vehicle 14, 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 104, 106, 108, 110 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. One inventive feature of the system is the use of a neural network 50 with an associated trainer 54 to modify 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]...
