摘要： Methods and systems are provided for diagnosing a stuck Active Transmission Warmup (ATWU) valve. In one example, a method for an ATWU valve monitoring routine of a vehicle comprises determining a temperature difference between an engine coolant temperature (ECT) and a transmission fluid temperature (TFT) over a duration before the ATWU valve is commanded from a closed position to an open position or from the open position to the closed position comparing a rate of change of the TFT before and after the ATWU valve is commanded to the open position or the closed position; and indicating a stuck ATWU valve based on at least one of the temperature difference, the TFT rate of change comparison, or a combination thereof, based on a calibration parameter.

摘要： The invention relates to a method (100) for determining the flow direction (R) of a coolant (M). The coolant (M) flows past at least two adjacent components (K1, K2) one after the other in order to cool the components (K1, K2). The method has the following steps: ascertaining a first temperature (110) which is paired with the first component (K1) of the at least two adjacent components; ascertaining a second temperature (115) which is paired with the second component (K2) of the at least two adjacent components; ascertaining the difference (120) between the ascertained temperatures; and determining the flow direction (190) of the coolant on the basis of the ascertained difference.

摘要： To estimate an engine cooling water temperature, four learned neural networks (150A, 150B, 150C, and 150D) are stored, in which weights are learned for the four states of whether the grille shutter (50) is opened and whether air blown by the blower (63) circulates through the air-conditioning use heater (65). The engine cooling water temperature is estimated using any one of the learned neural networks selected from among the four learned neural networks (150A, 150B, 150C, and 150D). An abnormality of the engine cooling water recirculation system is detected based on the estimated value of the engine cooling water temperature.

摘要： A waste heat recovery system in thermal communication with an exhaust conduit of an internal combustion engine of a vehicle includes a condenser. The condenser includes a working fluid conduit configured to connect to a working fluid loop of the waste heat recovery system and a coolant fluid conduit configured to connect to a coolant fluid loop used to cool the internal combustion engine of the vehicle. The coolant fluid conduit includes a coolant fluid inlet and a coolant fluid outlet. The waste heat recovery system also includes a coolant fluid bypass fluidly connected between the coolant fluid inlet and the coolant fluid outlet. The coolant fluid bypass includes a coolant fluid control valve configured to vary a portion of the volume of coolant fluid that flows through the coolant fluid bypass based on a temperature of a working fluid in the working fluid loop.

摘要： Methods and systems are provided for a cooling system valve comprising a fusible insert and a heating element coupled to the insert. In one example, in response to an increase in coolant temperature to above a first threshold temperature, a movable element of the cooling system valve may be actuated to a fully open position and in response to an increase in coolant temperature to above a second threshold temperature with the movable element in a fully open position, electric current may be routed through the heating element to heat and melt the fusible insert. By melting the fusible portion, coolant may flow through an opening created in the movable element.

摘要： A cooling apparatus includes: a cooling circuit that includes three flow passages intersecting at an intersection point and allows a cooling liquid to circulate therethrough; a three-way valve that is disposed at the intersection point and is switchable such that any two of the three flow passages communicate with each other; and a controller that controls switching of the three-way valve. The controller includes an intermediate fixation determination unit. The intermediate fixation determination unit determines that the three-way valve is in an intermediate fixation state in which the three flow passages simultaneously communicate with one another, when a cooling liquid temperature difference between one of the two flow passages that are controlled to communicate with each other, and a remaining flow passage of the three flow passages that is not controlled to communicate, is smaller than a predetermined value.

摘要： A valve is configured to control a flow amount of cooling water flowing in a main passage. A detour passage connects an engine to the main passage through the valve. A failsafe valve includes a valve body, which operates independently from the valve and enables the detour passage to open or close, and a temperature detection medium which manipulates the valve body based on a temperature of cooling water and enables the detour passage to open or close. A branch point is point at which an inlet point in which cooling water from the engine flows is branched to a bypass passage and the detour passage. The temperature detection medium does not protrude to the branch portion and is housed in the detour passage.
