Patent Images
1. A heater control apparatus for a vehicle provided with a heater core case, a temperature control lever, a temperature control lever angle sensor, an interior temperature sensor, wherein said vehicle heater control apparatus comprises:
- a cooling water bypass extending between a cooling water inlet conduit and a cooling water outlet conduit in the heater core case, the cooling water inlet conduit being in fluid communication with the cooling water outlet conduit through the cooling water bypass;
an engine control part for outputting a control signal in order to control an opening mode of the conduits comparing a signal generated from the temperature control lever angle sensor and a signal generated from the interior temperature sensing sensor with reference to corresponding set-point values;
a relay controlled in accordance with a control signal generated from the engine control part; and
a cooling water conduit control part for allowing the cooling water to be bypassed via the cooling water bypass in accordance with the control signal generated from the engine control part after the relay is turned on, the cooling water conduit control part being installed in the cooling water bypass.

8. A method for controlling a vehicle heater control apparatus comprising a cooling water bypass extending between a cooling water inlet conduit and a cooling water outlet conduit in the heater core case, an engine control part for outputting a control signal based on comparing a signal generated from the temperature control lever angle sensor and a signal generated from the interior temperature sensing sensor with corresponding set-point values, a relay being turned on in accordance with a control signal generated from the engine control part, and a cooling water conduit control part for allowing the cooling water to be bypassed via the cooling water bypass in accordance with the control signal generated from the engine control, the method comprising:
-
determining whether an interior temperature sensed by the temperature sensor is higher than a first preset standard temperature or not after receiving a control signal, which corresponds to an air conditioning mode, from the temperature control lever angle sensor;
determining whether the interior temperature is higher than a second preset standard temperature or not, in a state that the interior temperature is higher than the first preset standard temperature;
controlling an opening mode of the conduits by turning on the relay and by completely closing the cooling water inlet conduit and the cooling water outlet conduit and by fully opening the cooling water bypass, in a state that the interior temperature is higher than the second preset standard temperature; and
controlling an opening mode of the cooling water bypass by turning on the relay and by opening the cooling water bypass in accordance with the increase of the interior temperature, in a state that the interior temperature is higher than the first preset standard temperature and also is lower than the second preset standard temperature. - View Dependent Claims (9, 10)
