Document Type and Number:
Japanese Patent JP4078742
Kind Code:
B2
Abstract:
A control apparatus and method for controlling an automotive heater apparatus. The heater apparatus includes a coolant circuit for cooling an engine, a coolant circulating through the circuit, a heat generator for transferring heat to the coolant, and a heater core for transferring heat from the coolant. The heat generator houses a viscous fluid and a rotor selectively connected to and disconnected from the engine by a clutch. The clutch connects the engine with the rotor to shear the viscous fluid and generate heat. When the rotating speed of the rotor exceeds a rotor speed limit, which varies in accordance with the detected coolant temperature, the clutch disconnects the rotor of the heat generator from the engine and de-activates the heat generator.
