Abstract:
In a car-mounted air-conditioner driven by a mechanical power source provided on a car and capable of starting the operation for cooling or warming the air in the car room or cabin at a preset time under the control of a microcomputer, the microcomputer is interrupted at the preset time to be caused to compare the air temperature of the car room with a preset temperature and only when the air temperature is found to be outside a suitable temperature range, the microcomputer actuates the mechanical power source to start the operation of the air-conditioner.
Abstract:
An aircraft hybrid electrical propulsion (HEP) system includes an electrical system configured to deliver power to a plurality of electrical loads, a propulsion system configured to generate thrust in response to an input power, and an HEP controller in signal communication with the electrical system and the propulsion system. The HEP controller is configured to monitor a load demand of at least one electrical load among the plurality of electrical loads and to actively control the input power to actively control the thrust in response to changes in the load demand.
Abstract:
An engine system for an off-highway vehicle includes a diesel engine configured to drive a driveline of the vehicle; an after-treatment arrangement configured to reduce emissions from the engine system; an after-treatment heating element configured to raise an operating temperature of the after-treatment arrangement; an electric energy storage device; and a controller configured to direct energy from the electric energy storage device to the after-treatment heating element in order to raise the operating temperature of the after-treatment arrangement.
Abstract:
An electronic control for engine block heater elements for heating an engine to an engine ready temperature includes a power input, a power output, and a controller. The controller includes a clock for keeping a time and a temperature sensor for sensing a temperature. The controller is configured for controlling the power from the power input to the power output in at least two modes of operation for heating the engine to the engine ready temperature. The second mode of timed ready is where the power from the power input to the power output is connected at a pre-calculated time interval for the purpose of making ready the subject vehicle for starting at the desired start time as set by the user. The third mode of maintain ready is where the power from the electrical outlet to the engine block heater element is regulated to maintain the engine ready temperature.
Abstract:
A hybrid electric vehicle drive apparatus has a setting portion for setting a limit value of a driving torque that a motor outputs when driving a hybrid electric vehicle by the power of the motor only, based on a maximum torque that the motor enables to output and a starting torque used to start an internal combustion engine by the motor. The setting portion sets the limit value to a first value and sets the limit value to a second value which is greater than the first value when a vehicle speed of the vehicle does not increase even though an accelerator pedal position degree increases while the vehicle is being driven only by the motor.
Abstract:
The present patent application relates to a high-voltage motor vehicle electrical system comprising an electrical heating device and at least on further consumer during switching on of which, undesired electromagnetic oscillations may occur in the electrical system. According to the invention, these are suppressed by initially switching on the heating device, before the further consumer is switched on. Switching on the heating device changes the complete impedance of the electrical system such that a resonant enhancement of the interference oscillations is prevented. Preferably, the heating device is switched on only as shortly as possible (only during the switching on process of the further consumer) in order to minimize an undesired heating.
Abstract:
A vehicle temperature control apparatus for controlling temperature of a temperature control object, which is at least one of inside air of a vehicle compartment and a vehicle component, includes a heat capacitive element capable of storing heat, a refrigeration cycle in which heat is absorbed from a low temperature side and is dissipated to a high temperature side, a heat exchanger that causes the heat capacitive element to exchange heat with refrigerant of the refrigeration cycle, and a heat dissipation portion which dissipates heat in the refrigerant of the refrigeration cycle to the temperature control object. Thus, a temperature control by using the heat capacitive element can be effectively performed.

Abstract:
A fuel cell system estimates a characteristic of an electric power generation of a fuel cell before a supply of an electric power is permitted from the fuel cell to an outside load, restricts or prohibits characteristic of the electric power generation of the fuel cell when a temperature of the fuel cell is equal to or lower than a first prescribed temperature.
