摘要： A thermal management system for use in a vehicle includes a first cooling circuit for cooling a battery; and a second cooling circuit for cooling an electric motor configured to drive the vehicle. The first and second cooling circuits are connected to each other: (a) in series by a multi-way valve in a first mode of the thermal management system and in a first valve position of the multi-way valve, or (b) in parallel in a second mode of the thermal management system and in a second valve position of the multi-way valve. In a third mode of the thermal management system and in a third valve position, the multi-way valve is configured to take up an intermediate position in which coolant flows of the first and second cooling circuits are mixed with each other as needed.

摘要： A vehicular heater includes a heat medium circuit connected to a heater core that heats vent air via heat exchange with a heat medium. The heat medium circuit includes a first flow path connected to the heater core through a power unit, and a second flow path arranged in parallel with the first flow path and connected to the heater core through a heat source different from the power unit. A controller adjusts a first flow rate of the heat medium in the first flow path to be larger than a second flow rate of the heat medium in the second flow path when the power unit is operating.

摘要： Systems and methods for providing an improved strategy for controlling a variable speed water pump in a vehicle. In some embodiments, more than one water pump speed function is calculated based on values obtained from vehicle sensors, and a controller chooses among the water pump speed function results to set a water pump speed. In some embodiments, the water pump speed is increased when driveline torque is greater than a threshold amount for an amount of time that varies based on the driveline torque. In some embodiments, ambient temperature is considered while determining whether the water pump should provide full coolant flow to an auxiliary coolant loop of a trailer.
