摘要:
A vehicle includes a power feeding inverter that converts at least one of power discharged by a storage apparatus and power generated by activating an engine into alternating current power. The vehicle detects the presence of a user within a predetermined range of the vehicle using at least one of a seat occupancy sensor, a camera provided on the exterior or in the interior of the vehicle, and a reception unit that receives ratio waves from a smart key. When a request for power feeding from the vehicle is issued but the user has not been detected within the predetermined range of the vehicle, power generation by activating the engine is prohibited.

System (17) for managing a supply voltage (B+A) of an onboard electrical network of a motor vehicle comprises a device (2, 4, 9, 16) for regulating the supply voltage and a device (10, 11) for protecting the onboard electrical network against overvoltages, the two devices together controlling an excitation of an alternator supplying the onboard electrical network. According to the invention, the protection device is separate from the regulating device. An overvoltage signal (OVD) generated by the protection device (11) and controlling the excitation has priority over an excitation signal (EXC) generated by the regulating device. The regulating device and the protection device can be in the form of two separate electronic blocks on separate substrates.

A power supply system mounted in a vehicle. A rotary machine is connected to an output shaft of an internal-combustion engine of the vehicle, and has a power generation function, an engine start-up function, and an engine output assist function. A first secondary battery and a second secondary battery are each electrically connected in parallel with the rotary machine. A connection switch is provided along a connecting line electrically connecting the first and second secondary batteries, where the connection switch is configured to electrically connect and disconnect the second secondary battery and a parallel connection of the first secondary battery and the rotary machine. A switch controller is configured to disconnect the second secondary battery and the parallel connection by controlling the connection switch to a current cut-off state during the engine start-up and during engine output assist.

An operation mode selection unit selects an efficiency priority mode for minimizing the overall loss in a power supply system based on a load request voltage obtained in accordance with the condition of a load and on the conditions of DC power supplies, and generates a mode selection signal in accordance with the selection result. When SOC and/or output power have/has reached power supply restriction values in any DC power supply, an operation mode modification unit generates a final mode selection instructing signal so as to modify selection of the efficiency priority mode by the mode selection signal to select an operation mode in which power distribution between the DC power supplies can be controlled.

In a vehicle control apparatus, a system controller that overall controls an engine controller and a converter controller is provided. The system controller drives, through the converter controller, a generator with a generator-rotational-speed command value ωc_ref1 smaller than idling maintenance minimum rotational speed ωe_idol_min of an engine, starts, through the engine controller, fuel injection to the engine after elapse of a predetermined time, and, when the rotational speed of the engine reaches a predetermined rotational speed threshold ωe_th that is larger than the generator-rotational-speed command value ωe_ref and smaller than the idling maintenance minimum rotational speed ωe_idol_min, outputs, to a converter, a gate cutoff signal GSTOP for turning off energization to the generator.
摘要:
In a method for starting a motor vehicle having a first vehicle electrical system, to which a battery of the motor vehicle is assigned, a second vehicle electrical system, to which an electric machine of the motor vehicle is assigned, and a DC/DC converter for connecting the two vehicle electrical systems, for starting, electrical energy from the second vehicle electrical system is converted via the DC/DC converter and transferred into the first vehicle electrical system if an actual value of at least one operating parameter of the battery falls below a setpoint value prior to a starting operation to be carried out.
