    摘要： A crank permission system includes first and second permission modules and a crank module. The first permission module selectively generates a first permission signal, based on a first gear range engaged within a transmission, when an ignition system transitions to crank. The second permission module selectively generates a second permission signal, based on (i) the first gear range stored when the ignition system last transitioned to off and (ii) a second gear range of the transmission requested by a driver using a transmission range selector, when the ignition system transitions to crank. The crank module begins cranking an engine via a starter, in response to the generation of at least one of the first and second permission signals, when the ignition system of the vehicle transitions to crank.

    摘要： A method is provided for controlling the engine torque delivered during engine operation. The method includes, but is not limited to setting a brake torque request value during the engine operation, deriving a request fuel quantity value on the basis of the brake torque request value. The comparison of the value of the brake torque requested with a measured and/or estimated brake torque value allows calculating a brake torque error value, which directly or indirectly modifies the request fuel quantity injected in the engine.

    摘要： A transmission system of a vehicle includes a starting clutch, a change clutch, a stepped transmission, a single spindle, a gear position sensor, an actuator, and a transmission controller. The change clutch and the stepped transmission are operated via the single spindle. The gear position sensor is to detect a shift stage of the stepped transmission. The actuator is to rotate the single spindle. The transmission controller, in a case where an engine is started in a state in which the shift stage of the stepped transmission is set in second gear or higher, is configured to control the actuator to carry out shift-down operation and configured to limit output of the engine so that an engine rotation speed becomes a value smaller than a predetermined value until the shift stage of the stepped transmission is set in neutral or first gear.

    摘要： A system and method for minimizing torque disturbances during a shift event for an automatic transmission control actual transmission input shaft torque using a transmission input shaft signal produced by an input shaft torque sensor. The torque sensor provides a signal to a controller that monitors the measured transmission input torque. The torque sensor may be implemented by a strain gauge, a piezoelectric load cell, or a magneto-elastic torque sensor. The system may include a vehicle powertrain having an engine, a transmission coupled to the engine via a torque converter, an input torque sensor coupled to the input shaft of the transmission and a controller configured to control engine torque to cause the measured transmission input shaft torque to achieve a target transmission input shaft torque during the shift event.

    摘要： Described herein is a control system for a vehicle with an infinitely variable transmission (IVT) having a ball planetary variator (CVP), providing a smooth and controlled operation. In some embodiments, the vehicle is a fork lift truck. An operator commands a brake pedal, an accelerator pedal, a direction switch (or gear selector), and a hydraulic lever, which are evaluated by the control system to determine a current operating state of the vehicle. Some operating states include, forward drive, reverse drive, vehicle braking, automatic deceleration, inching, power reversal, vehicle hold, and park, among others. The control system is configured to determine a commanded engine speed based at least in part on the hydraulic lever signal.
