This invention relates to the field of vehicle control, specifically to a windshield wiper supplementary wiping control method, device, and vehicle. This application, upon triggering regular wiping with a valid raindrop, simultaneously opens a supplementary wiping detection window starting from the wiping moment, expanding the detection range from monitoring only valid raindrops to covering all raindrops in the range, providing a detection entry point for tiny raindrops that do not reach the effective threshold but affect visibility. Secondly, by setting graded perturbation thresholds, different intensities of raindrops are distinguished, enabling effective identification of tiny raindrops that do not reach the effective threshold but exceed the tiny raindrop threshold, fundamentally solving the problem of missed detection of tiny raindrops. Finally, differentiated supplementary wiping strategies are matched for different threshold ranges, ensuring visibility clarity in light rain while avoiding false triggers, solving the technical pain point of existing technologies that lack specific control for tiny raindrops, resulting in automatic wiping in light rain scenarios and requiring manual intervention.

This disclosure relates to the field of vehicle technology, specifically to a method, device, and vehicle for controlling windshield wiper mis-wiping. The method includes: acquiring key environmental data related to weather type from environmental data of the vehicle's environment; comparing the key environmental data with a preset numerical range corresponding to a sunny weather type to obtain a first comparison result; if the first comparison result indicates that all key environmental data fall within the preset numerical range, then verifying the validity of the currently detected rainfall signal, and controlling the vehicle's windshield wipers to perform wiping after confirming that the rainfall signal has passed the validity verification. This disclosure uses multi-dimensional key environmental data to determine sunny weather, replacing the traditional single-judgment logic based solely on light intensity. It distinguishes between true sunny weather and strong light interference from non-sunny weather at the source, significantly reducing the probability of mis-wiping on sunny days. Rainfall signal verification is only initiated in true sunny weather scenarios, avoiding the verification logic affecting the response speed in light rain, focusing on mis-wiping scenarios on sunny days, and thus offering better adaptability.

This invention discloses a device and method for testing the water permeability of waterproof textile fabrics, relating to the field of waterproof material testing technology. The water permeability testing device, relying on a reciprocating swing mechanism composed of a power component, levers, counterweights, and torsion springs, can simultaneously achieve pulse spraying, swing spraying, and fabric reciprocating stretching in a synchronized cycle.
