摘要： An electric motor is subjected to PWM duty control based on a target speed (tgt spd) set according to a position of a wiper blade. After a deceleration start position of wiping operation, the electric motor is driven at a PWM duty value (sld sta duty×Ksd) obtained by multiplying a PWM duty value (sld sta duty) at the deceleration start position by a predetermined deceleration coefficient (Ksd) set according to the blade position. The deceleration coefficient (Ksd) is set according to the position of the wiper blade based on a ratio (tgt spd/pek tgt spd) between the target speed (pek tgt spd) of the wiper blade at the start of deceleration and the target speed (tgt spd) of the wiper blade.

摘要： A wiper system 1 has a wiper blade 5 for performing a reciprocating wiping operation on a windshield glass 6 and a brushless motor 2 for causing the wiper blade 5 to perform the reciprocating wiping operation. The motor used as the brushless motor 2 is provided with a rotary shaft for reciprocating the wiper blade 5, has a degree of operation freedom in three axial directions, and is rotatable about axes of two directions orthogonal to the rotary shaft. The wiper blade 5 operates at error angles θ different in direction between during a forward-path wiping operation and during a return-path wiping operation. When the wiper blade 5 reaches a reversing position, the brushless motor 2 is made to rotate about an axis extending in a extending direction of the wiper blade 5 to change the error angle θ.

摘要： A system has an acceleration region SU and a deceleration region SD between operation start and end positions of a wiper arm. In the acceleration region and the deceleration region, an addition amount and a subtraction amount are calculated, respectively, based on a difference between a maximum rotation speed and a current rotation speed to update a target rotation speed. The addition amount is larger than the subtraction amount, and a constant speed region CV is between the acceleration region SU and the deceleration region SD. When a change amount of an operation angle of the wiper arm does not exceed the constant speed region CV, the operation angle change amount is subtracted from the constant speed region. Further, when the operation angle change amount exceeds the constant speed region CV, the target rotation speed is updated by the same change amount.

摘要： A wiper system according to the present invention includes wiper blades (2a, 2b) that perform a reciprocating wiping operation on a windshield (3), and a raindrop sensor (9) that detects the current amount of rainfall based on water droplets adhering to the windshield (3). If rainfall more than or equal to a predetermined amount is detected by the raindrop sensor (9), a heavy rain mode in which a wiping range of the wiper blades (2a, 2b) is made narrower than in a normal wiping operation is carried out. In the heavy rain mode, the wiper blade (2a) arranged on the driver's side is activated at high speed (Hi) within a heavy rain time wiping area X set near the forward field of view of the driver to ensure the field of view of the driver.
