| 20110231045 | CONTROL SYSTEM FOR EQUIPMENT ON A VEHICLE WITH A HYBRID-ELECTRIC POWERTRAIN - A power take off system for a hybrid-electric vehicle comprises an internal combustion engine, a hybrid-electric motor and generator, a power take off mechanism, a control module, and an engaging mechanism. The motor and generator couples to the internal combustion engine. The power take off mechanism couples to the internal combustion engine and the motor and generator. The power take off mechanism receives torque from at least one of the engine and the motor and generator. The control module is disposed in electrical communication with a system controller. The control module generates output signals for controlling the engine. The engaging mechanism is disposed in electrical communication with the system controller. The engaging mechanism has a first mode and a second mode. The power take off mechanism is decoupled from the engine and the motor and generator in response to an output signal generated by the system controller. | 09-22-2011 |
| 20110224858 | CONTROL SYSTEM FOR EQUIPMENT ON A VEHICLE WITH A HYBRID-ELECTRIC POWERTRAIN - 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. | 09-15-2011 |
| 20110126782 | THERMOSTATIC CONTROL OF VEHICLE HEATER COOLANT CIRCUIT TO MAXIMIZE CABIN HEATER PERFORMANCE - A coolant circulation system for an internal combustion engine includes an exhaust gas recirculation system coolant circuit and a cabin heating circuit. The exhaust gas recirculation system coolant circuit includes a heat exchanger to extract heat from exhaust gases into the engine coolant. The cabin heating circuit includes a heat exchanger for sinking heat into a vehicle cabin. An exhaust gas recirculation flow control valve controls the flow of exhaust gas flowing through the exhaust gas recirculation line and through the line heat exchanger. The exhaust gas recirculation flow control valve is closed when the engine is not warm enough. A heater control valve controls the flow of coolant through the cabin heating circuit. Opening and closing of the heater control valve is made responsive to direct or indirect indication of engine temperature in order to maintain engine temperature by restricting flow to the cabin heating circuit. This keeps the exhaust gas recirculation valve open which maximizes heat input to the coolant, which in turn maximizes heat available to warm a vehicle cabin. | 06-02-2011 |
| 20110031046 | MULTIPLE BATTERY SYSTEM OF A MOTOR VEHICLE - An electrical system for a motor vehicle includes first and second battery sets. The first battery set generally supplies power to vehicle electrical loads while the second battery set is used to energize the engine starter system. The vehicle's engine driven alternator is connected to recharge the first battery set. Recharging of the second battery set is provided by a charger connected to draw power from the first set and to transfer the power to the second set. | 02-10-2011 |
| 20100320826 | Integrated Mounting Flange For School Bus Seats - A modified seat frame incorporates a wall riser having an integrated mounting flange to reduce welding operations and to reduce the number of parts required to build and install a modular school bus seat. | 12-23-2010 |
| 20100181827 | CONTROL SYSTEM FOR A BATTERY POWERED VEHICLE - A control system for a battery powered vehicle of the kind which is provided with an electric power source and at least one switch means, such as a contactor, which is operable to connect the output of the power source to a high power electrical item fitted to the vehicle, such as an electric drive motor, in which the control system is operable to set the vehicle in one of at least 3 different operating modes comprising a first mode in which the vehicle is immobilised and the contactor is held in an open position to isolate the battery from the electrical item, a second mode in which the vehicle is not immobilised and the contactor is held in a closed position to connect the battery to the electrical item, and a third mode in which the vehicle is immobilised but the contactor remains in an closed position to connect the battery to the electrical item. | 07-22-2010 |
| 20090096601 | EXTENDING HAZARD FLASHER DURATION WITH KEY OFF BY MINIMIZING CURRENT DRAW - A vehicle flasher hazard function is implemented on an electrical controller having control over vehicle exterior lights. The flasher hazard function features an optimized duty cycle and operational frequency, consistent with legal requirements for the flasher rate. The point in time that individual bulbs are turned on is staggered in time to avoid all bulbs being simultaneously activated. This distributes the current surges associated with bulb activation being distributed in time. When a vehicle battery can no longer sustain the legally mandated flasher rate an optional path for flasher operation at a reduced rate is provided. | 04-16-2009 |
