A vehicle cruise control system includes an ECO-cruise mode such that a rate of acceleration of the vehicle during cruise control is less than or equal to a maximum that is a function of vehicle speed and road grade. Further, the rate is a function of the vehicle speed and a difference between the vehicle and target cruise control speeds. 1. A vehicle cruise control system comprising:at least one controller programmed to, in response to a decrease in vehicle speed relative to a target cruise speed in an absence of driver acceleration demands, cause the vehicle to accelerate at a rate (i) less than or equal to a maximum that depends on road grade and the vehicle speed and (ii) that depends on the vehicle speed and a difference between the vehicle and target cruise speeds.2. The system of claim 1 , wherein the rate decreases as the road grade increases.3. The system of claim 1 , wherein the rate increases as the vehicle speed increases.4. The system of claim 1 , wherein the maximum increases as the vehicle speed increases.5. The system of claim 1 , wherein the maximum increases as the road grade increases.6. A method of controlling vehicle speed comprising:receiving a target cruise control speed and a cruise control operating mode;selecting a speed control gain based on the cruise control operating mode and a difference between vehicle speed and the target cruise control speed;generating a weighted speed error from the difference based on the speed control gain;generating a road gradient compensation ratio based on the cruise control operating mode and a road gradient force representing a road grade; andaccelerating the vehicle at a rate based on the road gradient compensation ratio, the weighted speed error, and the vehicle speed such that the rate increases as the vehicle speed increases when the road grade is generally constant in an absence of driver acceleration demands and the rate decreases as the road grade increases in the absence of driver acceleration ...

VEHICLE POWERTRAIN LASH CROSSING CONTROL STRATEGY

Номер: US20190329785A1
Автор: FARMER Mary Catherine, Feldpausch Terry Gene, FINK Mitchell Thomas, Kuechler Peter Douglas, Reed Dennis Craig
Принадлежит:

A vehicle includes a powertrain and a controller. The powertrain includes a powerplant. The controller is programmed to, responsive to a tip-in resulting in a powertrain torque direction reversal and upon obtaining a base value of a desired powertrain lash angle, adjust a powerplant torque schedule. The controller is then subsequently programmed to adjust the desired powertrain lash angle from the base to an adjusted value based on an observed powertrain lash angle that corresponds to a maximum powertrain acceleration during the tip-in.

A system and method for controlling backlash in a vehicle powertrain includes the step of controlling a torque request of the powertrain with a first control strategy after an occurrence of a backlash predictor and before an occurrence of a backlash. Another step may be employed whereby the torque request is controlled with a second control strategy after the first control strategy and before the occurrence of the backlash such that a torque request level is below a highest torque request level obtained during the first control-strategy. 1. A method for controlling backlash in a vehicle powertrain , comprising:controlling a torque request of the powertrain with a first control strategy after occurrence of a backlash predictor and before occurrence of a backlash; andcontrolling the torque request with a second control strategy after the first control strategy and before the occurrence of the backlash such that a torque request level is below a highest torque request level obtained during the first control strategy.2. The method of claim 1 , wherein the first control strategy includes increasing the torque request to a first predetermined level and holding the torque request constant until the torque request is controlled according to the second control strategy.3. The method of claim 1 , wherein the first control strategy includes increasing the torque request at a first rate to a first predetermined level claim 1 , and claim 1 , after reaching the first predetermined level claim 1 , increasing the torque request at a second rate different from the first rate until the torque request is controlled according to the second control strategy.4. The method of claim 1 , wherein the second control strategy includes increasing the torque request to a second predetermined level and holding the torque request constant until the occurrence of the backlash.5. The method of claim 1 , wherein the second control strategy includes increasing the torque request at a third rate to a ...

A system and method for controlling backlash in a vehicle powertrain includes the step of controlling a torque request of the powertrain with a first control strategy after an occurrence of a backlash predictor and prior to an occurrence of backlash. The first control strategy is modified when backlash occurs during the first control strategy. The torque request is controlled with the modified first control strategy after another occurrence of a backlash predictor and before another occurrence of backlash. 1. A method for controlling backlash in a vehicle powertrain , comprising:controlling a torque request of the powertrain with a first control strategy after an occurrence of a backlash predictor and prior to an occurrence of backlash;modifying the first control strategy when backlash occurs during the first control strategy; andcontrolling the torque request with the modified first control strategy after another occurrence of a backlash predictor and before another occurrence of backlash.2. The method of claim 1 , wherein modifying the first control strategy includes reducing a duration of the first control strategy.3. The method of claim 2 , wherein the first control strategy includes increasing the torque request to a first predetermined level claim 2 , and modifying the first control strategy further includes reducing the first predetermined level when the duration of the first control strategy is reduced to a first predetermined duration.4. The method of claim 1 , further comprising controlling the torque request with a second control strategy after the first control strategy and before the occurrence of backlash such that a torque request level is below a highest torque request level obtained during the first control strategy;modifying the second control strategy when backlash occurs during the second control strategy; andcontrolling the torque request with the modified second control strategy after another controlling of the torque request with the first ...

Ein Verfahren zum Steuern eines Drehmomentrichtungsübergangs in einem Doppel kupplungsgetriebe beinhaltet das Senken einer Drehmomentkapazität einer Getriebeingangskupplung, wenn der Kupplungsschlupf während einer Power-Off-Bedingung einen Zielschlupf erreicht, Erzeugen einer nachfolgenden Power-On-Bedingung und Erhöhen der Drehmomentkapazität der Kupplung, wenn der Kupplungsschlupf einen zweiten Zielschlupf erreicht. One method of controlling a torque direction transition in a dual clutch transmission involves lowering a torque capacity of a transmission input clutch when clutch slip reaches a target slip during a power-off condition, generating a subsequent power-on condition, and increasing the clutch's torque capacity when clutch slip achieved a second target slip.
