It doesn't feel as good as a manual wiper. It's ok at high speed. In downtown, you have to shave all the time by hand. Manual gear is not suitable, either too fast or too slow. Automatic wipers are not sensitive at all. Sometimes it's hanging all the time, sometimes it's invisible. It feels worse than a manual wiper. It's ok at high speed. In downtown, you have to shave all the time by hand. Manual gear is not suitable, either too fast or too slow. Automatic wipers are not sensitive at all. Sometimes when I go to the 4S store, it always hangs, and I don't think I know what to do. I don't know what to do when asking questions. These situations are mostly circuit problems. Go back to the local 4s shop and check the wiring of some related sensors, some of which are fuse parts. Once there is a problem in these places, they will not be used in the future, and the parts that affect the whole vehicle in subsequent related parts are within the scope of relevant quality warranty services. After passing the general inspection, if it is really not good, you can go back and deal with it for free. This is a long-standing problem of induction wiper, and there is no good way to apply to all cars. Sometimes I feel sensitive, sometimes I don't. Now there is a patented technology that can perfectly solve the long-standing problem of Hongqi H5 induction wiper (invention patent: an intelligent control method and device for wiper, application number: 201811162162. x)。 The significance of this intelligent solution is that it does not change any hardware (combination switch) of Hongqi H5 induction wiper system. Let users experience the stepless speed regulation and working stability of the wiper. 1) This scheme takes the wiper of Hongqi H5 smart car as an example. Without changing any hardware of the existing Hongqi H5 wiper system, only by modifying the BCM software, the lowest sensitivity gear of the sensitivity adjustment switch of the existing Job Hongqi H5 induction wiper is set as the "lock" function gear (see the figure below). When the sensitivity toggle switch of the red flag H5 induction wiper is set to the lowest position (i.e. the current wiper speed is locked), the wiper control system of BCM locks the PWM signal that drives the wiper motor speed corresponding to the wiper speed at this time, so that the PWM signal does not change with the rainfall until the sensitivity toggle switch leaves the lowest position and is set to other gears (including the wiper system leaving the automatic induction wiper working gear and returning to the manual gear). 1) Through the above automatic sensing wiper "locking" function, the "stepless" speed regulation of the wiper is realized (the real-time wiper speed is locked to be constant). 2) "Lock" the speed of the wiper when the rainfall is very small, which can perfectly replace the INT function and make the wiper move stably. 3) It solves the long-standing problem that the induction wiper sometimes stops scraping and sometimes suddenly scratches several times when the rainfall is unstable or the driving environment is unstable (road bumps and temporary shelter). The core functions of the intelligent wiper solution include: 1) sensing the rainfall through the rainfall sensor, and automatically setting the wiper speed according to the rainfall, that is, the wiper speed automatically changes with the rainfall. 2) "Lock" the wiper speed automatically set according to the rainfall is a fixed wiper speed, that is, the locked wiper speed is fixed and does not change with the rainfall, thus realizing the stepless speed regulation of the manual wiper (making up for the shortage that the manual wiper only has two gears of "fast" and "slow"). 3) Manually correct the wiper speed automatically set by the rainfall sensor according to the rainfall. 4) Manual and manual correction of the fixed wiper speed locked in function (2). Contrast: The core function of the traditional induction wiper is 1) sensing the rainfall through the rainfall sensor, and automatically setting the wiper speed according to the rainfall, that is, the wiper speed automatically changes with the rainfall. 2) The sensitivity of the rainfall sensor can be adjusted. @20 19
