    摘要: A method for operating a speed control system of a vehicle is provided. The method comprises receiving one or more electrical signals representative of vehicle-related information. The method further comprises determining, based on the signals representative of vehicle-related information, whether one or more predetermined conditions are met. The method still further comprises automatically determining a baseline set-speed for the speed control system when it is determined that at least certain of the one or more predetermined conditions are met. The method yet still further comprises adjusting the baseline set-speed to determine an instantaneous set-speed of the speed control system based on a signal indicative of a desired comfort level. A speed control system comprising an electronic control unit configured to perform the above-described methodology is also provided.

    摘要: A method for operating a speed control system of a vehicle having a plurality of wheels is provided. The method comprises receiving one or more electrical signals representative of vehicle-related information. The method further comprises determining, based on the one or more electrical signals representative of vehicle-related information, that one or more of the wheels of the vehicle have overcome an obstacle or are about to overcome an obstacle and that therefore a reduction in an applied drive torque to one or more of the wheels of the vehicle by a powertrain subsystem (applied drive torque) will be required to maintain the speed of the vehicle at a target set-speed of the speed control system. The method still further comprises automatically commanding the application of a retarding torque to one or more of the wheels of the vehicle to counteract the effect of an overrun condition in the powertrain subsystem from increasing the speed of the vehicle. A system for controlling the speed of a vehicle comprising an electronic control unit configured to perform the above-described methodology is also provided.

    摘要: A method for operating an off-road speed control system of a vehicle is provided. The method comprises identifying a pattern or change in at least one component of vehicle drag. The method further comprises monitoring vehicle speed to predict where a change in the at least one component of vehicle drag may result in a speed overshoot event or a speed undershoot event. The method still further comprises, in response to the predicted speed overshoot event or speed undershoot event, automatically commanding the application of an appropriate opposing torque to one or more wheels of the vehicle to counteract the predicted speed overshoot or undershoot. An off-road speed control system for a vehicle comprising an electronic control unit (ECU) configured to perform the above-described methodology is also provided.
