Abstract: A control device that controls an automatic transmission is provided, in which device the automatic transmission includes a variator disposed in a power transmission path between a driving source and a driving wheel of a vehicle, and a friction engaging element disposed between the variator and the driving wheel, in a manner capable of transmitting a power disconnectably via the power transmission path. The control device increases a speed ratio of the variator toward a predetermined target speed ratio with disengaging the friction engaging element during a vehicle stop of the vehicle, and executes a learning regarding a hydraulic control of the friction engaging element when the friction engaging element is disengaged during the vehicle stop. The control device decreases the target speed ratio at a time of learning when the learning is executed during the vehicle stop, compared to a time of vehicle stop other than the time of learning.

Abstract: The object of the invention is to impart a suitable target slip amount depending on a state of change in an output from a driving power source (engine 2) to a torque converter 1, while simplifying control. A controller has an input torque change rate detection means (step S1 of Fig. 2 ) for detecting an engine torque change rate ΔTe that is the output, and a target slip addition amount calculation means (step S2 of Fig. 2 ) for calculating a negative value as an addition amount Δslip, when the engine torque change rate ΔTe is less than or equal to a predetermined value that is a positive value, and for calculating a positive value as the addition amount Δslip, when the engine torque change rate is greater than the predetermined value. The controller 10 is configured to set the target slip amount TSLIP of a lockup clutch 8 by arithmetic processing that integrates the addition amount Δslip, determined based on the detected engine torque change rate ΔTe, every control period (step S3 of Fig. 2 ).

Abstract: A maximum flow calculating unit (166) calculates a maximum amount (Qmax) of hydraulic fluid that can flow into or out of an input-side hydraulic cylinder (42c) when a shift control command signal (S T ) is set to a reference DUTY value, based on an estimated valve pressure difference (ΔP) calculated by an estimated pressure difference calculating unit (156), and a post-guard target sheave position setting unit (170) performs a guard process for restricting the amount of change of the sheave position, using a guard value (ΔXg) calculated by a guard value calculating unit (168) based on the maximum flow amount (Qmax), so as to set a post-guard target sheave position (Xtg). Since the thus set target sheave position (Xtg) does not undergo excessive large changes nor excessively small changes during shifting, a target value for shifting is set so that a feedforward controlled variable determined based on the amount of change of the target sheave position (Xtg) becomes an appropriate value.

Abstract: The method involves determining a first distance (TA) from the vehicle (F) to a target object (Z), a vehicle range (deltaskupplaus) assuming no interaction between engine and drive wheels, a second distance (sziel) depending on the first distance and a definable tolerance range (DSZIEL) so the second distance and tolerance sum to less than the first distance, determining a gear ratio so the engine is operated in shut-off mode if the gear is engaged with the drive wheels and engine and ensuring engagement if the range exceeds the sum of the second range and tolerance. Independent claims are also included for the following: (a) a controller for a vehicle; (b) a vehicle; and (c) a computer program for running on a controller for implementing the inventive method.
