Abstract:
A vehicle coasting deceleration control system has a motor/generator arranged in a drive-train of a vehicle. A controller is configured to determine a driver demand regarding deceleration of the vehicle at a time of coasting accompanied by an accelerator releasing operation. The controller is further configured to control the motor/generator to decelerate the vehicle according to the determined driver demand regarding deceleration.

Abstract:
Provided is a hybrid construction machine capable of facilitating the hybridization (conversion, redesigning, etc. into a hybrid construction machine) even for construction machines of the minimal tail swing radius type or the minimal swing radius type. A hybrid mini-shovel of the minimal tail swing radius type comprises an engine 11, a hydraulic pump 21 whose input shaft 21a is coaxially connected to the output shaft 11a of the engine 11, a generator/motor 31 whose rotating shaft 31a is connected to the output shaft 11a of the engine 11 and the input shaft 21a of the hydraulic pump 21 via a gear mechanism 6, and a battery 33 which receives and supplies electric power from/to the generator/motor 31. The generator/motor 31 is placed at a vertical position where its lower end is situated above the shaft center of the input shaft 21a of the hydraulic pump 21, and when viewed from above at a horizontal position where it overlaps with the hydraulic pump 21.
Abstract:
A control apparatus of a hybrid vehicle includes an automatic transmission (12), a clutch (16), a motor (8), a battery (6), a driving assist control device (26) performing a driving assist control by driving the motor to generate an assist torque, a gear shift assist control device (26) performing a gear shift assist control by driving the motor in response to a decrease of the engine torque caused by the disengagement state of the clutch, an SOC value detection device (48) detecting an SOC value, and a first mode switch device (24) switching an operation mode of the hybrid vehicle from a normal mode in which the driving assist control and the gear shift assist control are performed to a battery power preserving mode in which the driving assist control is prohibited and the gear shift assist control is permitted in a case where the SOC value is equal to or smaller than a first predetermined value.
Abstract:
A working machine includes a prime mover for supplying torque to the driving wheels of the working machine, and a transmission line arranged between the prime mover and the driving wheels for transmitting torque from the prime mover to the driving wheels. The transmission line includes a gearbox arranged between the prime mover and the wheels, and the working machine further includes at least one hydraulic machine in a hydraulic system for moving an implement arranged on the working machine and/or steering the working machine, and an electric machine for driving or braking the driving wheels and/or for driving or braking the at least one hydraulic machine. The electric machine is arranged in parallel with the prime mover with respect to the transmission line and is mechanically connected to the transmission line between the prime mover and the gearbox. The gearbox is a continuously variable transmission having a variator unit, and the gearbox has an operation mode where the rotation speed of the output shaft of the gearbox is zero or close to zero independently of the rotation speed of the input shaft of the gearbox at the same time as torque can be transmitted from the input shaft to the output shaft.

The present invention relates to a utility vehicle (2), in particular an agricultural tractor, which has at least three driveable vehicle axles, having a front axle (18), a middle axle (20) and a rear axle (22). The utility vehicle (2) has a drive (4), an adjustable transmission arrangement, which has at least one adjustable transmission unit (32, 34), wherein a drive input of the transmission arrangement is connected in respect of the drive to the drive unit (4) and a drive output from the transmission arrangement is connected in respect of the drive to the three vehicle axles (18, 20, 22), in such a way that the three vehicle axles ( 18, 20, 22) can be driven by the minimum of one adjustable transmission unit (32, 34) and a longitudinal and at least partially hollow frame element (12), which runs longitudinally and essentially centrally in the utility vehicle (2). The minimum of one adjustable transmission unit (32, 34) is in this case formed integrally in the frame element (12), and a drive output of the minimum of one adjustable transmission unit (32, 34) leads into the cavity of the frame element (12).
