Condensation management for internal combustion engines

A system, comprising:

• an internal combustion engine including an intake system with an intake manifold, a compressor, and a charge air cooler upstream of the intake manifold and downstream of the compressor;
• a coolant circuit connected to the charge air cooler for supplying a coolant to the charge air cooler, the coolant circuit including a coolant control valve for controlling a flow of the coolant in the coolant circuit;
• an electronic controller connected to the internal combustion engine and the coolant control valve, wherein the electronic controller is configured to:
• determine a condensation condition for the charge air cooler in response to a humidity condition in the intake system upstream of the compressor and a pressure in the intake system downstream of the compressor;
• determine a lower limit for a target temperature of the coolant in response to the condensation condition and an upper limit for the target temperature in response to one or more engine protection conditions;
• and
• adjust the coolant control valve in response to the condensation condition to maintain a temperature of the coolant between the lower limit and the upper limit.
