Abstract:
1. An operation signal generator for generating and outputting an operation signal to operate a wiping system on a window comprising: a detection means for detecting an amount of watery liquid in a form of droplets on the window in a period of a wiping cycle; a calculation means for calculating an increase rate of the amount of the watery liquid in the form of droplets detected in a detection operation by the detection means; a determination means for determining a window condition based on the increase rate calculated by the calculation means, wherein the determination means determines the window condition as condensation when the increase rate in the period of the wiping cycle is greater than a predetermined value; and a mode selection means for selecting an operation mode of the wiping system, wherein a fastest operation mode in the mode selection means is overridden when the determination means determines the window condition as condensation.
