A control apparatus for hybrid electric vehicle includes a shift operation detector and an electric motor controller. The shift operation detector detects an input of a shift operation. The electric motor controller controls an electric motor of the hybrid electric vehicle to generate motor torque directed to decreasing of torque difference, on a condition that: the input of the shift operation from a first stage into a second stage is detected by the shift operation detector; and first torque and second torque are different in magnitude from each other by the torque difference. The first torque is torque that is to be transmitted to a drive wheel during shifting of the automatic transmission. The second torque is torque that is to be transmitted to the drive wheel after the shifting of the automatic transmission is completed.

A vehicle control method includes: acquiring information on acceleration, information on rotational speed of a drive wheel, and information on driving force; after a dropping state where a calculated speed indicative of a vehicle body speed calculated from the rotational speed is less than an estimated speed indicative of a vehicle body speed in a front-rear direction estimated from the acceleration has transitioned to a non-dropping state and a holding period in which the non-dropping state is held has passed, determining whether or not a reset condition to reset the estimated speed is satisfied; when the reset condition is satisfied, determining whether or not the driving force is less than a threshold value; and when the driving force is less than the threshold value, resetting the estimated speed and setting a current value of the calculated speed to a vehicle body initial speed used for estimating the estimated speed.

Drive mechanism (1) for a motor vehicle (6), comprising a dual clutch transmission (10) that includes a first powertrain (13), which can be connected to a first drive unit (2) via a first clutch (21), and a second powertrain (14), which can be connected to the first drive unit (2) via a second clutch (22), the first powertrain (13) being securely coupled to a second drive unit (3); when shifting gears in the dual clutch transmission (10), the second drive unit (3) supplies a predefined drive torque.

A vehicle includes an engine and an electric machine coupled to a gearbox. A controller is programmed to predict, at an onset of a shift, a supplemental torque profile to fill a torque hole expected during the shift and an available electric machine torque during the shift. The controller is further programmed to, in response to the supplemental torque profile exceeding the available electric machine torque during the shift, operate the engine from the onset to achieve a torque reserve in anticipation of increasing the engine torque.

A method for managing a drive mode of a tracked vehicle, comprising the step of reading an output of a sensor and in response to the output of the sensor performing a control action to manage the drive mode of the vehicle.

An agricultural vehicle and method of controlling the same are provided, the vehicle having a motive power unit providing a driving torque to at least one driven wheel and having at least one tire or track frictionally coupled with the periphery of the driven wheel. A vehicle operating parameter is controlled in dependence on the driving torque and a slippage characteristic relating the respective driving torque at which the frictional coupling between driven wheel and tire or track begins to slip for a range of vehicle operating parameter values. The operating parameter is suitably a tire pressure or track tension, and the control may involve reducing driving torque or increasing pressure/tension to prevent slipping.

A transmission includes an input shaft and an output shaft, the input shaft selectively accepting a torque input from a prime mover, and the output shaft selectively providing torque output to a driveline. A controller determines a shaft displacement angle representing an angle value of rotational displacement difference between at least two shafts of the transmission, and performs a transmission operation responsive to the shaft displacement angle.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.
