Claims

[Scope of claim for utility model registration] (1) A deceleration sensor that detects the deceleration of the vehicle, a wiper drive means, and a wiper drive means that receives a signal from the deceleration sensor and automatically adjusts the wiper speed or intermittent time according to the deceleration. A window wiper comprising: a controller for outputting a signal to the wiper drive means to change the signal to the wiper drive means. (2) The wiper driving means includes a Hi terminal for rotating the wiper motor at high speed and a Lo terminal for rotating the wiper motor at low speed, and the controller includes a moving speed determining means for outputting a signal when the deceleration reaches a predetermined value or more;
The window wiper according to claim 1, further comprising a drive circuit for switching the wiper drive means to the Hi terminal in response to a signal from the moving speed determining means. (3) The controller includes an intermittent time determining means that determines an intermittent time according to the deceleration, and a drive circuit that receives a signal from the intermittent time determining means and drives the wiper driving means at the determined intermittent time. The window wiper according to claim (1), characterized in that: (4) a deceleration sensor that detects the deceleration of the vehicle, a vehicle speed sensor that detects the vehicle speed, and a wiper drive means;
a controller; the controller includes first intermittent time determining means for determining the wiper intermittent time according to the deceleration detected by the deceleration sensor;
a second intermittent time determining means for determining the wiper intermittent time according to the vehicle speed detected by the vehicle speed sensor;
Comparing means for comparing the intermittent times determined by the first intermittent time determining means and the second intermittent time determining means and outputting a short intermittent time; and the wiper driving means receiving the output from the comparing means. and a drive circuit that drives the above-mentioned in a short intermittent time.
