Abstract:
The purpose of the present invention is to improve the operation efficiency of an internal combustion engine while supplying a required drive force for an electric motor. A power generation control device determines the appropriateness of power generation by a power generator in accordance with the state of a storage battery, and when allowing power generation, sets the amount of power generation equivalent to an output required for cruising in accordance with a travelling state, while setting an additional amount of power generation in accordance with the amount of power required depending on a vehicle state and the traveling state.
Abstract:
A warm-up apparatus for a vehicle including a system which charges a battery by using an external power supply is provided. The warm-up apparatus includes a heater for warming up, a current detector, a voltage detector and a resistance changer. The heater is mounted in the vehicle and produces heat by receiving electric power from the external power supply. The current detector detects an allowable current value of the external power supply. The voltage detector detects an output voltage value of the external power supply. The resistance changer changes an electric resistance value of the heater based on the allowable current value detected by the current detector and the output voltage value detected by the voltage detector.

Abstract:
Methods and systems are provided for processing information associated with vehicles via one or more servers of a cloud system. One example method includes establishing a communication link between a computing device associated with a vehicle and a server. The communication link is over a wireless network and the communication link is established in association with a user account. The communication link is established for one or more sessions The method further includes receiving, at the server, a plurality of actions associated with inputs to the vehicle. The plurality of actions are received during the one or more sessions, and generating, by the server, a recommendation to program a setting at the vehicle. One or more of the plurality of actions at the vehicle during the one or more sessions are processed to determine a confidence score associated with generating the recommendation to program the setting. Generation of the recommendation occurs upon reaching or exceeding a predefined threshold. The server then sends to the user account the recommendation to enable programming of the setting for the vehicle.
Abstract:
The present disclosure is related to a method for regenerative braking of a machine. The machine includes an electric drive assembly. The electric drive assembly includes a generator, a motor and a direct current bus and a regenerative brake assembly disposed between them. The regenerative braking assembly includes an inverter. The method includes connecting a phase leg between the direct current bus and the inverter. The phase leg includes an inductor and an electric switch. The phase leg boosts the regenerative voltage. The boosted regenerative voltage is then fed back to control a braking torque from the motor and directed back to the generator.
Abstract:
A temperature adjustment apparatus has a Peltier element supplied with electric power to allow heat exchange between an electronic device mounted on a vehicle and a heat exchange portion of the vehicle, and a Peltier element control section that controls electric power supplied to the Peltier element. When the temperature difference between a first surface of the Peltier element serving as an exothermic surface and a second surface of the Peltier element serving as an endothermic surface becomes larger than a first predetermined value as a result of supply of electric power to the Peltier element, the Peltier element control section stops supply of electric power to the Peltier element.
Abstract:
A system and method for operating a fuel-cell system, which is attached to at least one further component via a cooling and/or lubricating circuit. A water-based, oil-free coolant and lubricant is used, and a flushing procedure for the fuel cell is initiated when a contamination of the fuel cell by the water-based, oil-free coolant and lubricant is detected.
Abstract:
According to one embodiment, a battery pack includes a battery module that houses unit cells, a heat storage portion including a heat storage container that houses a heat storage member, cooling passages through which heat of the heat storage portion is spread and discharged, and a cooling source that cools the heat storage portion. The heat storage member absorbs heat when changing from solid to liquid and dissipates heat when changing from liquid to solid. The heat storage container is thermally connected to the battery module. The cooling source is driven to circulate cooling medium to the cooling passages, and heat of the heat storage portion discharged through the passages are discharged to the outside.
Abstract:
A vehicle having a vehicle system is provided with a motor having a housing and a stator. The motor is configured to provide motor torque for vehicle propulsion. The vehicle system is also provided with at least one controller that is configured to receive input indicative of at least one of the housing temperature and the stator temperature, and control the motor torque based on a comparison of the input to predetermined thermal data.
