Abstract: A vehicle having a hydraulic hybrid powertrain comprises a power take off unit, a hydraulic pump, a hydraulic accumulator, an accumulator isolation valve, an accumulator solenoid, and a vehicle hydraulic component. The hydraulic pump mechanically connects to the power take off unit and is driven by the power take off unit. The hydraulic accumulator is disposed in fluid communication with the hydraulic pump and receives and stores pressurized hydraulic fluid from the hydraulic pump. The accumulator isolation valve has a first position and second position. The accumulator isolation valve is disposed in fluid communication with the hydraulic accumulator. The accumulator solenoid connects to the accumulator isolation valve and positions the accumulator isolation valve to the first position and the second position. The vehicle hydraulic component is disposed in fluid communication with the accumulator isolation valve and the hydraulic accumulator.

Abstract: An isolation system for traction batteries for a vehicle includes battery contactors having a closed state and an open state. The current drawn from the traction batteries during transitions between the two states is managed by selecting loads for either reduced levels of operation or cutoff to reduce the total current draw. Vehicle operating conditions, such as the direction of the state transition, may control the selection of loads for operation during the transition.

Abstract: A motor vehicle with a system for conditioning power take-off enablement has a powerplant, including an internal combustion engine, for propelling the vehicle. The powerplant is disposed within a compartment. A hood is positionable relative to the compartment to selectively allow and disallow access to the compartment. A power take-off unit comprises an input mechanically coupled to the powerplant and selectively enabled by a controller for coupling an output of the power take-off unit to the input of the power take-off unit when enabled by the controller and uncoupling the output of the power take-off unit from the input of the power take-off unit when not enabled by the controller. A device whose status distinguishes between the hood allowing access to the compartment and the hood disallowing access to the compartment causes the controller not to enable the power take-off unit when the device discloses that the hood is allowing access to the compartment.

Abstract: A parallel hybrid electric vehicle is equipped for power take-off operation in both an electrical and a thermal engine mode. A parallel control enables an operator to restart the vehicle's internal combustion engine using a remote command.

Abstract: A hybrid electric motor vehicle (12) has a combustion engine (14), a high-voltage battery bank (28), a low-voltage battery bank (30), an electric generator (32) driven by engine (14) for recharging battery bank (30), a DC-to-DC converter (46) for recharging battery bank (30) from battery bank (28), a monitor for indicating voltage of battery bank (30), a recharge initiate timer that, while battery bank (28) and not generator (32) is recharging battery bank (30) via converter (46), is started by the monitor indicating that voltage of battery bank (30) is below a recharge initiate threshold and whose rate of timing is a function of voltage indicated by the monitor as the timer times. If the timer times to a recharge initiate limit, the generator begins recharging battery bank (30).

Abstract: A hybrid electric work vehicle having an electric traction motor driven power take off used in conjunction with a control system that monitors the hydraulic system for pressure deltas and trend vectors, and that has learning capabilities, is provided for use with a vehicle for operation on the ground. The system is usable for both open center and closed center hydraulic systems. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Abstract: A control system for a hybrid-vehicle equipped with power takeoff equipment provides control over primary and redundant, relatively low output systems so that the redundant system is not damaged by concurrent operation of the primary system.

Abstract: A control system for a hybrid vehicle equipped with power takeoff equipment provides a multi-bus, network environment, integrating operation of a vehicle electric traction motor, power takeoff equipment including prospectively hydraulic motion control equipment and a vehicle thermal engine. The control system is readily programmable to allow reconfiguration depending upon the character of the equipment installed. Efficient utilization of the vehicle's thermal engine and enhanced system robustness is obtained.

Abstract: A power take off unit for a motor vehicle equipped with a standard transmission is clutched using compressed air available on the vehicle. Available air pressure is monitored and a clutch interlock implemented through the vehicle electrical control system is made responsive thereto to prevent engagement of the clutch if the load is too heavy for the available air pressure.

Abstract: A circuit (26) for configuring a seven-terminal receptacle socket (10) in a towing vehicle to properly accommodate the particular one of several possible electric circuit configurations in a particular trailer that is being towed by the towing vehicle. The particular electric circuit configuration in the trailer—FIGS. 3, 4, 5, 6 are four possible configurations—depends on the particular lamps (52, 54, 56, 58, 72, 74) and brakes (50, 80) in the trailer.
