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.
A vehicle comprising:
A method of controlling a speed of a variable-speed pump configured to provide coolant flow to a gear box cooler, the method comprising:
A non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by a pump controller of a vehicle, cause the pump controller to perform actions to control a speed of a variable-speed pump configured to provide coolant flow to a gear box cooler of the vehicle, the actions comprising:
