摘要: A cooling device is employed in a vehicle including an internal combustion engine provided with a forced-induction device and an intercooler. The cooling device includes a circulation circuit configured to circulate coolant supplied to the intercooler, an electric pump configured to operate to circulate the coolant in the circulation circuit, and processing circuitry configured to control a discharge amount of the coolant of the pump. The processing circuitry is configured to execute a control amount deriving process of deriving a control amount of the pump based on a requested flow rate and a coolant temperature, and an operation process of causing the pump to operate based on the control amount when the requested flow rate is larger than 0.

摘要: Models that employ both measurable engine parameters as well as predictable engine parameters may be used to determine when a thermostat is malfunctioning before the thermostat malfunction results in an engine breakdown. Particular models may be used to provide an estimated coolant temperature and an estimated thermostat position. The estimated coolant temperature can be compared to an actual measured engine coolant temperature. The estimated thermostat position can be evaluated with respect to what the thermostat position should be given a particular engine coolant temperature. In some cases, comparison between a healthy model and a faulty model may be used to ascertain thermostat health.

摘要: A cooling device includes a first cooling medium circuit for circulating a cooling medium that passes through a main body of an engine to a first heat exchanger, a second cooling medium circuit for circulating a cooling medium that passes through the main body to a second heat exchanger, a control valve that is commonly used in the first and second cooling medium circuits, and a control device. The control valve includes a rotatable rotor, and is configured such that a rotation range of the rotor includes a water stop section in which the circuits are both closed. The control device restricts output power of the engine in a period in which the rotation angle is in the water stop section, when the rotor rotates via the water stop section at an operating time of the control valve.

摘要: A drive device comprising at least one control unit (10) for operating a first drive unit (16) with a first operating frequency (fb1) from a first operating frequency interval and a second drive unit (18) with a second operating frequency (fb2) from a second operating frequency interval, which at least partly overlaps the first operating frequency interval. The control unit (10), in at least one operating state, operates the drive units at least occasionally simultaneously with different operating frequencies (fb1, fb2) and varies the first operating frequency (fb1) and/or the second operating frequency (fb2) within the respective operating frequency interval.

摘要: Methods and systems are provided for controlling coolant flow through parallel branches of a coolant circuit including an AC condenser and a charge air cooler. Flow is apportioned responsive to an AC head pressure and a CAC temperature to reduce parasitic losses and improve fuel economy. The flow is apportioned via adjustments to a coolant pump output and a proportioning valve.

摘要: An ECU includes a motor control unit that controls energization to a motor, and a fixation determination unit that makes a determination on fixation of a valve body. The motor drives the valve body housed in a housing of a control valve. When the fixation determination unit has determined that the valve body is fixed, the motor control unit performs fixation-time control that energizes the motor so as to drive the valve body.

摘要: A method and a system for controlling a vehicle cooling system includes: a velocity prediction unit makes a prediction of at least one future velocity profile vpred for the vehicle; a temperature prediction unit predicts at least one future temperature profile Tpred for at least one component in the vehicle, based on at least tonnage for the vehicle; information related to a section of road ahead of the vehicle and on the at least one future velocity profile vpred. A cooling system control unit controls the cooling system based on the at least one future temperature profile Tpred and on a limit value temperature Tcomp_lim for the respective at least one component in the vehicle so that a number of fluctuations of an inlet temperature Tcomp_fluid_in_radiator for the cooling fluid flow into the radiator is reduced and/or so that a magnitude of the flow into the radiator is reduced when a temperature derivative dT/dt for the inlet temperature Tcomp_fluid_in_radiator exceeds a limit value dT/dtlim for the temperature derivative.

摘要: The present disclosure relates to a system for controlling an air flow rate into a vehicle engine room. The system includes: an air intake port receiving an exterior air at a front portion of the vehicle and supplying the air into the engine room; air ducts formed at both sides of the air intake port and introduce the exterior air into a wheel side in order to improve aerodynamic characteristic; a control valve configured to selectively convey the air flowed in the air intake port into the air ducts; a radiator disposed between the air intake port and the engine room; and a control portion configured to control the control valve based on an operating state of vehicle. The air ducts are selectively communicated with the air intake port and disposed at upstream of the radiator.

摘要: The invention relates to a coolant pump having an impeller which is arranged on a pump impeller shaft and having a drive device for the impeller, which drive device has a mechanical drive and an electric-motor drive. The impeller shaft is divided into a driving section and a driven section, and an openable and closable clutch is arranged between the driving section and the driven section. Operation of the coolant pump by either the mechanical drive or the electric-motor drive can be dependent upon a predetermined speed of threshold of rotation of the impeller, and/or upon a predetermined power usage threshold.
