Document Type and Number:
Japanese Patent JP3601886
Kind Code:
B2
Abstract:
An automotive air conditioning system comprises a heater/cooler unit having therein a plurality of control doors by which various air flow modes are provided. A plurality of identical actuators are provided for actuating the control doors. Each actuator includes an electric motor for driving the corresponding control door, a position detector for issuing a current position signal representative of a current angular position assumed by the corresponding control door, and a control circuit for controlling the electric motor based on the current position signal as well as a target position signal applied thereto. A control unit is provided for integrally controlling the actuators by means of a bi-directional serial transmission method. The control unit issues the target position signal to each of the actuators and thereafter judges whether the actuator issues or not a target position accomplishment signal which represents that the corresponding control door has been set to the target position. A display device is further provided for displaying the result of the target position accomplishment judgment carried out by the control unit.
