ELECTRIC PARTS CONTROLLER FOR VEHICLE

摘要

PURPOSE:To reduce containing space for electric parts and to enable compensation of defective portion upon occurrence of trouble by forming respective control units such as wiper control section on a single IC board and controlling respective electric parts through a multiplex transmission cable. CONSTITUTION:Control signals for electric parts 4 are fed to a signal processor IC6 corresponding to signals fed from various switches then multiplexed through a multiplex transmitting/receiving section 20 and transmitted through a transmission cable 9 to a multiplex transmitting/receiving section 22 at the side of a driving module 8. The electric parts 4 are driven through a power converting section 24 based on the signals received at the multiplex transmitting/receiving section 22. Output signals from sensors provided for the electric parts 4 are transmitted through the multiplex transmitting/receiving section 22 to the side of IC6. Upon trouble of the electric parts 4, signals are fed from the sensors to a trouble compensating section 16 and optional operation control signals can be outputted in response to the sensor signals.
