A work management system includes a generator attached to a structure body that is provided to a transmission case of a working machine, configured to be driven by power transmitted from a PTO shaft, and configured to transmit power to a working device provided in the working machine, an information obtaining portion configured to obtain operation information representing operation of the working device that is activated by the power from the generator, a work management portion configured to manage working of the working device based on the operation information obtained by the information obtaining portion, and a controller portion configured to control the working device based on the operation information obtained by the information obtaining portion.

A fire fighting vehicle includes a chassis, tractive elements coupled to the chassis, a pump coupled to the chassis, a discharge fluidly coupled to the pump, an accessory module coupled to the chassis, and an electric motor coupled to the chassis, the pump, and the accessory module. The accessory module is configured to receive a mechanical energy input and provide at least one of electrical energy or fluid energy. The electric motor is configured to provide mechanical energy to drive (a) the pump to provide fluid to the discharge such that the fluid is expelled from the discharge and (b) the accessory module to provide the at least one of electrical energy or fluid energy.

A working vehicle includes a prime mover, a driver's seat selectively set in either a first posture where a driver can sit thereon or a second posture where the driver cannot sit thereon, a speed controller to receive power from the prime mover and perform a speed-changing of the power, a PTO shaft to receive the speed-changed power from the speed controller, a posture switch to detect whether the driver's seat is set in the first or second posture, a parking switch to detect parking of a vehicle body, and a first actuator. During driving of the prime mover, the first actuator maintains the driving of the prime mover when both the parking and the driver's seat set in the second posture are detected, and stops the driving of the prime mover when neither the parking nor the driver's seat set in the second posture is detected.

A hybrid multi-mode power take off system (PTO) installed on a vehicle includes an internal combustion engine, a first electric reversible electric machine, a second electric reversible electric machine and one epicyclical gear train connectable with the engine and the first and second reversible electrical machines by means of a number of clutches. An electronic control unit controls the closure/opening of clutches to implement different operating modes. The electronic control unit is configured to control the transfer of energy between the first and the second reversible electric machines when one reversible electric machine is operating as a motor and the other is operating as a generator.

A vehicle system for a vehicle includes a controller. The controller is configured to transmit a first control signal to a transmission of the vehicle to engage a first gear of the transmission, acquire information regarding a pressure of an inlet flow of water received by a pumping system of the vehicle, and transmit a second control signal to the transmission to engage a second gear of the transmission based on the information.

A hybrid vehicle drive system for a vehicle includes a first prime mover, a first prime mover driven transmission, and a rechargeable power source. The hybrid vehicle drive system further includes an interface between the transmission and the prime mover for coupling to an electric motor. The electric motor can be in direct or indirect mechanical communication with a hydraulic pump. The electric motor can receive power from the prime mover driven transmission through the interface.

Systems and methods are provided for an electrically driven power take-off (PTO). A motor generator is coupled to a PTO output shaft. The motor generator is capable of varying rotation speeds and direction. By extension, the PTO output shaft may also have varying speeds and directions. A control system is also provided to control the motor generator and, therefore, the PTO output shaft in accordance with a plurality of operating mode.

A power takeoff control system and method sense proximity of an operator to a power takeoff and control operation of the power takeoff based upon the sensed proximity.

A system includes a planetary gear assembly having a ring gear, a plurality of planet gears coupled to a carrier, and a sun gear coupled to a main shaft. The system further includes a driven gear coupled to the carrier, a countershaft gear coupled to the driven gear, a motor/generator coupled to the main shaft, and an actuator structured to change a coupling of the ring gear based on a position of the actuator.

A fire fighting vehicle includes a chassis, a front axle, a rear axle, an engine, an energy storage device, an electromechanical transmission, a vehicle subsystem, and a power divider. The electromechanical transmission is (i) coupled to at least one of the front axle or the rear axle and (ii) electrically coupled to the energy storage device. The power divider is positioned between the engine, the vehicle subsystem, and the electromechanical transmission. The power divider includes a first interface coupled to the engine, a second interface coupled to the vehicle subsystem, and a third interface coupled to the electromechanical transmission. The power divider is configured to facilitate (i) selectively coupling the engine to the vehicle subsystem and (ii) selectively coupling the engine to the electromechanical transmission.
