The embodiment of the invention provides a windscreen wiper switch control device and method.The windscreen wiper switch control device comprises an acquisition circuit, a controller and two drive circuits, and the acquisition circuit obtains windscreen wiper switch signals including a switch closing signal or a switch opening signal; the controller determines a windscreen wiper task type based on a time interval between the received switch closing signal and the switch opening signal, wherein the windscreen wiper task type comprises a windscreen wiper inching task or a windscreen wiper washing task; and then the controller sends a corresponding driving signal to the driving circuit based on the windscreen wiper task type, and the driving circuit executes a corresponding task based on the driving signal. Through the time interval between the switch closing signal and the switch opening signal, the wiper task type can be determined under the condition that only one acquisition circuit exists, the layout of the wiper switch is optimized, and the cost is reduced.

    本申请实施例提供一种雨刮开关控制装置及方法,雨刮开关控制装置包括:一个采集电路、控制器以及两个驱动电路,采集电路获取雨刮开关信号,包括开关闭合信号或开关断开信号;控制器基于接收到开关闭合信号和开关断开信号之间的时间间隔确定雨刮任务类型,雨刮任务类型包括雨刮点动任务或雨刮洗涤任务;之后控制器基于雨刮任务类型向驱动电路发送对应的驱动信号,驱动电路基于驱动信号执行相应的任务。通过开关闭合信号和开关断开信号之间的时间间隔可在仅有一个采集电路的条件下确定雨刮任务类型,优化了雨刮开关的布局,降低了成本。
