System Outline

Auto Wiper Operation 

* The wiper operates according to the wiper SW information from the windshield wiper SW assembly and wiper operation information from the rain sensor (HI, LO, AUTO, MIST)

* The auto wiper operation has the following functions.

1. Vehicle speed-sensing, adjustable interval INT function

   The intermittent interval is changed automatically according to the vehicle speed.

2. Vehicle speed switching function

   Judging whether the vehicle is driving or at a stop, the function changes the operating condition automatically between LO and INT.

3. Washer-linked wiper with drip-preventive function

The wiper makes three sweeps whenever washer liquid is output. Also, after a brief period has passed since the operation stopped, the wiper will make another sweep to prevent the washer liquid from dripping. The waiting time is adjusted automatically according to the vehicle speed.
