Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
Vehicle wiper device (hereinafter referred to as wiper is as shown in Figure 1) according to windscreen wiper corner auto-changing length is in fortune
During row, detecting the rotational angle theta of main brush in real time, then according to the corresponding relation of θ and R, this corresponding relation can pass through actually measured,
Control servomotor to turn an angle so that secondary brush stretches out, close to the edge of windshield.Wherein the corresponding relation of θ and R can
Record with the method by experiment and store in controller.So wiper just can be applied to all districts of windshield
Territory.
Elaborating embodiments of the invention below, the present embodiment is carried out under premised on technical solution of the present invention
Implement, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following enforcement
