Claims

[Scope of utility model registration request]

An operation switch for setting each of multiple operating modes of the wiper including the normal intermittent mode, a vehicle speed sensor that outputs a signal corresponding to the speed of the vehicle, and a signal from the vehicle speed sensor that corresponds to the stopped state of the vehicle. After a predetermined period of time has elapsed from the time when is output, regardless of the setting mode of the operating switch, a low-speed intermittent drive current is applied to the wiper motor to cause the wiper to perform intermittent operation at longer intervals than the normal intermittent mode. 1. A control device for a vehicle wiper, comprising: control means for energizing the wiper motor, and for energizing the wiper motor with a drive current corresponding to a setting mode of the operating switch when the vehicle resumes running.
