Abstract:
A vehicle in which propulsion can be distributed between first and second axles includes: a first electric motor coupled to the first axle and a second electric motor coupled to the second axle. An electric control unit (ECU) coupled to the motors causes electrical energy to be generated by the first motor in response to the ECU determining that a wheel speed of at least one wheel associated with the first axle exceeds the vehicle speed and causing electrical energy to be supplied to the second motor in response to electrical energy being generated in the first motor.
Abstract:
A fuel-efficient auxiliary power generation, conversion, and supply system configured within the periphery of a vehicular conveyance, and typically including a plurality of batteries, a power generator, an internal combustion engine, and an instrument control assembly including an inverter portion and a rectifier portion. The system generally comprises a portion of an electrical circuit substantially independent from a primary operative electrical circuit of the vehicular conveyance, and the combustion engine operates independently from a primary operative engine of the vehicular conveyance.
Abstract:
The system is directed to preserve the starter/alternator in an IC engine installation from potential overload and failure in response to electrical load increases. The system controller monitors starter/alternator output and phase current and regulates output voltage when monitored currents reach predetermined thresholds. Output voltage is stepped down incrementally to check output currents at threshold non-failure creating levels. When current demand, i.e., load, decreases, output voltage is stepped up incrementally to return to an original set point for voltage.
Abstract:
A limousine type vehicle includes a standard electrical system, a coach section with an auxiliary electrical system, and an electric power generation system which has first and second batteries isolated from each other during normal operation of the vehicle's engine. The first battery is electrically connected to the engine to supply electric power for the operation of the engine and the standard electrical system, and the second battery is electrically connected to the auxiliary electrical system to supply electric power for the operation of said auxiliary electrical system. A first alternator is electrically connected to the first battery to recharge said first battery during operation of the engine, and a second alternator is electrically connected to the second battery to recharge said second battery during operation of the engine. These alternators are electrically isolated from each other during normal operation of the engine, and they are mechanically coupled together and to the engine, so that the operation of the engine drives both the first and second alternators simultaneously.
Abstract:
A solar collector includes a roller rotatably attached to a vehicle. A carrier fabric panel is attached on one end to the roller. Side guides are attached the sides of the carrier fabric panel. Solar cells are connected in series and are attached to the carrier fabric panel. The solar cells are connected to an electrical power storage system. Electrical leads are attached to the carrier fabric and electrically coupled to the solar cells. Electrical conductors are attached to the carrier fabric between the solar cells and the right and left guides or are provided with retainer strips. A slip ring connector is disposed on the roller for electrically coupling the electrical conductors to an electrical power storage system. The solar energy collected may be used to power actuatable accessories or passive systems that may draw power when the vehicle is not being operated.
