ELECTRONIC CONTROL DEVICE FOR IN-VEHICLE AIR-CONDITIONER

摘要

PROBLEM TO BE SOLVED: To restrict a delay in response of each of a plurality of actuators for an in-vehicle air-conditioner for controlling them in a time-sharing basis. SOLUTION: There is provided an electronic control device 400 for use in controlling each of actuators in a time-sharing basis for driving each of doors arranged at an air-conditioner unit. This electronic control device 400 has a micro-computer 410 for periodically determining a target position of each of the actuators and a communication circuit 420 for transmitting these target positions to each of the actuators under a specified order and driving each of the actuators up to the target positions. A calculation period T2 where each of the target positions is calculated by the micro-computer 410 coincides with a transmittance period T1 where each of the target positions is transmitted by the communication circuit 420 and an end time of the calculation period coincides with a starting time of the transmittance period. Along with this operation, an offset time between the end time of the calculation period and the end time of the transmittance period is eliminated. COPYRIGHT: (C)2005,JPO&NCIPI
