Abstract: A coolant control system of a vehicle includes a target pressure module and a thermostat valve control module. The target pressure module determines a target pressure of coolant in a coolant path between a thermostat valve and at least one of an engine oil heat exchanger and a transmission fluid heat exchanger. The thermostat valve control module closes the thermostat valve and blocks coolant flow out of an engine when a temperature of coolant within the engine is less than a predetermined temperature. When the temperature is greater than the predetermined temperature, the thermostat valve control module controls opening of the thermostat valve to the coolant path based on the target pressure.

Abstract: A system for forming a weld nugget in a metal work piece includes a power supply, actuator, electrodes, and controller. The actuator delivers a variable electrode force to the work piece in response to a force command. The controller executes a method by transmitting a welding current command to the power supply to cause the power supply to output a welding current to the electrodes. The controller transmits the force command to the actuator to apply the variable electrode force, via the electrodes, to the work piece at a first force level. The variable electrode force increases from a second force level immediately upon conclusion of a first duration to minimize weld expulsion. The second force level commences at a point in time in the dynamic resistance profile at which a dynamic resistance value of the work piece decreases at a threshold rate during formation of the weld nugget.
