Systems and methods for operating a power take off of a vehicle are described. In one example, operation of the power take off may be maintained even when slip of a power take off clutch is detected. In particular, the power take off may be operated at a lower output until the power take off may handle larger loads.

The present disclosure describes methods, systems, apparatuses, and devices for facilitating actuating robots and automatic machines. Specifically, the present invention provides a capstan actuator with composite control coil. Further, the disclosed system may allow for multi-jointed robots, or other multiple degrees of freedom machines, to be constructed in a novel manner that allows for a single prime mover to supply motive power to many other degrees of freedom with very good control fidelity.

A power transmission device includes a friction clutch, an actuator, and a controller configured to determine an approximated temperature change of the friction clutch. The controller is configured to determine a current power state of the friction clutch, determine a desired power state change based on the current power state and a previous power state, determine a plurality of thermal coefficients based on a thermal coefficient model, the desired power state change, and a set of operation variables, determine an approximated temperature change of the friction clutch based on the thermal coefficients and a friction clutch temperature model, determine an approximated clutch temperature based on the approximated temperature change and a contemporaneous value of an device ambient temperature, and control operation of the actuator based at least on the approximated clutch temperature.

An apparatus for controlling a hybrid vehicle and a method thereof are provided. The apparatus includes a hybrid starter & generator (HSG) controller that determines whether an HSG has failed, and a hybrid vehicle controller that controls reverse drive by controlling locking up an engine clutch and maintaining a main relay of a battery to be continuously turned on, based on whether a request for the reverse drive is input from a user. The hybrid vehicle controller changes and applies a vehicle torque control calculation method based on a state of charge (SoC) of the battery, when the HSG has failed.

A clutch control device includes a clutch apparatus configured to connect and disconnect power transmission between an engine and a gearbox, a clutch actuator configured to output a driving force to actuate the clutch apparatus, and an ECU configured to drive the clutch actuator, and the ECU performs engine stalling avoiding control which decreases a clutch capacity when a reduction speed of an engine rotational speed becomes a predetermined threshold or more and the engine rotational speed becomes a predetermined engine stalling determination value or less.

A method of controlling a clutch for vehicle may include determining, by a controller, raised offset engine torque, when engine torque is raised to a reference torque or more in an engine idle state, and controlling, by the controller, the clutch based on the determined offset engine torque.

A creep control method for a vehicle is disclosed. The creep control method includes a limit-setting step and a limit release step. In the limit-setting step, a controller compares a speed of an input shaft of a transmission with a predetermined creep reference speed, and, if it is determined that the speed of the input shaft is lower than the creep reference speed, a creep minimum torque of a clutch for controlling creep driving of the vehicle is set to be a predetermined lower limit torque, which is larger than 0. In the limit release step, if the controller determines that the speed of the input shaft is increased above the creep reference speed while the creep minimum torque is limited to the lower limit torque, the creep minimum torque is set to 0.

A transmission for a vehicle having a prime mover with an output shaft. The transmission includes an offgoing clutch that is selectively connected to the output shaft, and a controller in communication with the prime mover. The controller includes an offgoing clutch control module that determines an offgoing clutch torque profile at the start of a torque phase in a power downshift that does not exceed a predetermined offgoing clutch energy threshold and a torque request module that limits a rate of input torque into the transmission from the prime mover based upon the determined offgoing clutch torque profile.

A control apparatus of a vehicle obtains information indicating a relationship between an instruction value to be provided to an actuator in accordance with a driving condition of a vehicle and a torque capacity of a clutch. The control apparatus includes a table holding unit that stores a correction table to be applied under a condition when an output torque from the engine is increasing and a correction table to be applied under a condition when an output torque from the engine is decreasing, a gear change condition determining unit that determines under which condition a gear change is executed, and a correction table update unit that updates the correction table to be applied under the determined condition based on the information indicating a relationship between a target value and an actual value of the torque capacity generated at the inertia phase.
