Abstract: A system includes a temperature estimation module and a pump control module. The temperature estimation module estimates a temperature of coolant flowing through an engine. The temperature estimation module estimates a temperature of a cylinder wall in the engine based on the estimated coolant temperature and a measured coolant temperature. The pump control module controls a coolant pump to adjust an actual rate of coolant flow through the engine based on the estimated cylinder wall temperature.

Abstract: A coolant control system of a vehicle includes a coolant valve control module and a pump control module. The coolant valve control module determines a position of a coolant valve. The pump control module determines a speed of a coolant pump based on the position of the coolant valve and a desired coolant output temperature, measures a coolant output temperature, determines a difference between the desired coolant output temperature and the measured coolant output temperature, generates a correction factor based on the difference between the desired coolant output temperature and the measured coolant output temperature, and applies the correction factor to the speed of the coolant pump.

Abstract: A system according to the principles of the present disclosure includes a coolant valve, a valve control module, and a fault diagnostic module. The coolant valve includes a first valve chamber, a second valve chamber, and a partition disposed between the first and second valve chambers. The coolant valve further includes a first end stop disposed on a first outer perimeter surface of the first valve chamber and a second end stop disposed on a second outer perimeter surface of the second valve chamber. The valve control module rotates the coolant valve in a first direction and in a second direction that is opposite from the first direction. The fault diagnostic module diagnoses a fault in the coolant valve based on a measured position of the coolant valve as the coolant valve is rotated in the first and second directions.

Abstract: A target speed module determines a target speed of an engine coolant pump of the vehicle. A speed adjustment module determines a speed adjustment based on a position of a valve, wherein a backpressure of the engine coolant pump changes when the position of the valve changes. An adjusted target speed module determines an adjusted target speed for the engine coolant pump based on the target speed and the speed adjustment. A speed control module controls a speed of the engine coolant pump based on the adjusted target speed.

Abstract: A system including a target module determining a target temperature of coolant at an input of an engine for a maximum amount of fuel efficiency. A mode module disables closed loop control based on temperatures of coolant entering the engine and at an output of a radiator. An open loop module determines first and second temperatures of coolant at inputs of a coolant control valve that receive coolant from the radiator and a channel that bypasses the radiator. A ratio module determines a ratio based on the first and second temperatures and the temperatures of the coolant entering the engine and at the radiator output. A closed loop module generates a correction value based on the target temperature and the temperature of the coolant entering the engine. A position module adjusts the coolant control valve based on the ratio, the correction value and whether closed loop control is disabled.

Abstract: A method is disclosed for improving fuel economy in an internal combustion engine. The method may involve sensing a temperature of an engine block and determining a block thermal energy representing an ability of the block to reject heat. An open loop control scheme may be used together with the block thermal energy to predict if a coolant in the block is about to enter a boiling condition and, when this is about to occur, to open a block valve to permit a flow of coolant through the block. A closed loop control scheme may be used together with the sensed temperature of the block to determine if a coolant boiling condition is about to occur, and to control the block valve to permit a flow of coolant through the block which is just sufficient to prevent the onset of coolant boiling in the block.
