Abstract

The invention discloses a rain wiper control system, which comprises a rain wiper combination switch, a rain wiper motor, a rain wiper low-speed relay and a rain wiper high-speed relay, wherein the rain wiper combination switch is provided with a zero gear terminal, an intermittent gear terminal, a low-speed gear terminal and a high-speed gear terminal; and the rain wiper motor is provided with a high-speed terminal and a low-speed terminal. The rain wiper control system is characterized by also comprising an automobile body controller, wherein the automobile body controller is connected with the rain wiper combination switch; the rain wiper low-speed relay and the rain wiper high-speed relay are connected with the automobile body controller; the high-speed terminal and the low-speed terminal on the rain wiper motor are connected with a power supply after passing through normally open contacts of the rain wiper low-speed relay and the rain wiper high-speed relay. According to the rain wiper control system and a rain wiper control method, control signals are isolated from a driving circuit; a rain wiper rubs glass for consumption to stop an automobile, instantaneous large current cannot be generated, and a phenomenon that contacts of the combination switch are burnt is stopped; and the rain wiper control system meets requirements for practicability and a low fault rate, reflects a humanized design concept, and has a wide market prospect.

Description

technical field [0001] The present invention relates to a wiper control system and a motor control method, more specifically, to a wiper control system and a motor control method in which the control signal is separated from the driving signal and the wiper uses frictional consumption to stop the vehicle. Background technique [0002] The wiper motors of domestic heavy-duty vehicles are mostly directly controlled by the wiper combination switch. bit. The large current generated when the wiper motor "brakes" can easily generate arcs between the contacts of the combination switch and ablate the contacts, so the failure rate of the wiper combination switch remains high. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, the present invention provides a wiper control system and a motor control method in which the control signal is separated from the drive signal and the wiper uses frictional consumption to sto...
