Abstract:
1. A wiper control device for controlling driving of a wiper device including a wiper blade provided on a surface to be wiped of a vehicle and an electric motor for driving the wiper blade, comprising: a storage section for storing a point value set corresponding to a load state of the electric motor; a point-value calculating section for detecting a current load state of the electric motor to calculate a load point value of the electric motor from the detected load state based on the point value stored in the storage section; a point-value adding section for accumulating the load point values to calculate an accumulated load point value; a point-value comparing section for comparing a difference between the accumulated load point value for forward operations of the wiper blade and the accumulated load point value for return operations of the wiper blade with a predetermined threshold value; a wiping-state determining section for detecting effects of a wind-pressure load due to a wind generated by running on the wiper blade based on results of the comparison in the point-value comparing section to determine whether the vehicle is in a high-speed running state; and a motor-driving command section for issuing an operation command to the electric motor based on results of the determination in the wiping-state determining section.
