Abstract
An inter-device communication system for a wiper control apparatus that includes a rain detection device and a wiper driving device includes communication circuits having a transmission line for unidirectionally sending a rain detection signal to the wiper driving device, a transmission circuit arranged in the wiper driving device for short-circuiting a potential of the signal unidirectionally sent through the transmission line, and a recognition circuit arranged in the rain detection device for recognizing transmitting information sent in an opposite direction to a direction of the unidirectional transmission, i.e., from the wiper driving device to the rain detection device based on the short-circuited signal.
