A method includes obtaining first fluidic pressure information indicative of fluidic pressure in a hydraulic cylinder of a machine as a function of time, and generating a first training set including second fluidic pressure information associated with impeller clutch engagement values. A training system associated with the machine computes a first plurality of test system response values based on the first training set, compares first plurality of test system response values with a plurality of observed response values, and determines a first response error. The training system determines whether the first response error is less than or equal to a threshold error value, generates a time-step predictive analytical model associated with the first training set, and provides the time-step predictive analytical model to an electronic control module of the machine. The time-step predictive analytical model is usable to control machine torque and/or an impeller clutch of the machine.

A hybrid electric vehicle and a method of controlling the same are provided to avoid a collision thereof attributable to erroneous operation of an accelerator pedal. The method includes determining whether an accelerator pedal is erroneously operated in the situation in which an obstacle is detected to be present in the traveling path. In response to determining that the accelerator pedal is erroneously operated, the method includes switching the driving mode to a mode in which an engine is disconnected from a driving shaft and a motor generates driving force. The number of revolutions per minute (RPM) of the engine is then adjusted based on the extent to which the accelerator pedal is operated and the torque of the motor is adjusted based on a first vehicle speed and the distance to the obstacle.

A vehicle drive device includes a first drive unit that drives first wheels; a second drive unit that drives second wheels; and a control device. When the state of charge of an electrical storage device is less than a first threshold value and a vehicle speed is less than a second threshold value, the control device performs control such that when the vehicle speed is greater than or equal to zero and required drive power is greater than or equal to zero, the operating mode of the first drive unit is set to a second mode to output the required drive power from the second drive unit, and when the vehicle speed is greater than zero and the required drive power is less than zero, the operating mode of the first drive unit is set to a first mode so the first drive power source can generate electric power.

A method for operating a dual clutch transmission of a motor vehicle having a first partial transmission, a second partial transmission, and a transmission output shaft common to the partial transmissions and drivable both by the first partial transmission and by the second partial transmission, in which the dual clutch transmission is in a parking lock state in which two gears of one of the partial transmissions are engaged simultaneously. The following steps are carried out to exit the parking lock state: Introducing a torque caused by a drive element of the motor vehicle via the transmission output shaft common to the one partial transmissions into the one and/or other partial transmission while the gears of the partial transmission are engaged; and disengaging at least one of the gears of the one partial transmission engaged simultaneously in step a).

The control unit is configured to permit the second clutch to be closed even when the hybrid drive is being operated purely electrically so that the driveshaft of the internal combustion engine is driven by the electrical machine. A control unit and a method for operation of a hybrid drive are also provided.

A vehicle running mode control method may include detecting, by a mode controller, a mode switching from an electric vehicle mode (EV mode) to a hybrid electric vehicle mode (HEV mode) while a vehicle runs; and performing a continuously variable transmission (CVT) cooperative mode switching control in which a drive motor is connected to an engine by engaging a clutch by operating the CVT.
