Claims

[Scope of Claim for Utility Model Registration] A fixed position stop switch is provided to detect whether the wiper blade is at a predetermined fixed position as a stop position, and the wiper blade is not at the fixed position due to the fixed position stop switch. is detected, the wiper motor is connected to the power supply via this fixed position stop switch, and when the fixed position stop switch detects that the wiper blade is in the fixed position, the wiper motor is connected to the power supply via the fixed position stop switch. A wiper control device for a vehicle in which the wiper motor is not connected to a power source, and includes a rain sensor that is installed on the surface wiped by the wiper blade and generates an electric signal according to the amount of rain that adheres thereto, and a predetermined a change detecting means for determining a change in the electrical signal from the rain sensor at a period determined by the rain sensor; Judgment means; When the judgment means judges that the change is not on the decreasing side from the reference value, the changes are sequentially integrated, and the judgment means determines that the change is on the reduction side from the reference value. If it is determined, the first step resets the integrated value.
determining whether the integrated value in the integrating means and the first integrating means is on the higher rainfall side than a predetermined first reference value;
A wiper operating means for operating the wiper on the heavy rainfall side; a second integrating means for sequentially integrating the integrated value in the first integrating means for a predetermined period; 2. Determine whether the amount of rainfall is higher than the standard value,
A wiper control device for a vehicle, comprising: speed switching means for increasing the operating speed of the wiper on a high rainfall side;
