Problems solved by technology

However, the above-mentioned automatic sensing wiper also has the following deficiencies: due to the complexity and unpredictability of the external environment changes in the driving process, such as: changes in wind direction or wind force, bumpy roads, roadside buildings or trees, etc. Due to the time delay of the mechanical actuator and the individual differences in the driver's preference for the wiper movement state, some drivers often feel that the wiper action of the automatic sensing wiper (for example: suddenly starting to wipe a few times or suddenly stopping) is different from the driver's expectation. It cannot be completely matched, which will cause the driver to experience unstable operation of the automatic sensing wiper, which will affect the user experience
At present, in the working state of the automatic gear of the automobile wiper, although there is a sensitivity adjustment switch for the driver to correct the intermittent time by setting different sensitivities of the rain sensor, the fixed intermittent time cannot be set through the sensitivity adjustment, that is, the intermittent time cannot be set to the size of the rainfall. irrelevant fixed value, which cannot effectively solve the problem of instability in automatic gear work

example 1

[0046] In this example, a virtual 6-position electrical shift switch is set to replace a physical 6-position electrical shift switch, and the physical shift switch is used by the driver to manually set different manual intermittent interval intervals. For the convenience of explanation, it is assumed that the adjustable range of the intermittent time of the manual intermittent gear is 2-12 seconds, and the value is set evenly in 6 intervals. , 2nd gear - 4 seconds, 3rd gear - 6 seconds, 4th gear - 8 seconds, 5th gear - 10 seconds, 6th gear - 12 seconds. The setting switch in the setting module of this embodiment includes three self-resetting button switches: switch 1, switch 2 and switch 3, "lightly press" the self-resetting button switch, and the switch is turned on; after the hand is released, the self-resetting button switch returns to Original position, the switch is disconnected again. Its function is shown as image 3 shown.

[0047] In this embodiment, the microproce...

example 2

[0065] The following example 2 illustrates the control process of the present invention through the one-key operation of the setting module to precisely select and set the fixed interval time.

[0066] In this example, the microprocessor sets a virtual 6-position electrical shift switch to replace a physical 6-position electrical shift switch, and the physical shift switch is used by the driver to manually set different manual intermittent interval intervals. For the convenience of explanation, it is assumed that the adjustable range of the intermittent time of the manual intermittent gear is 2-12 seconds, and the value is set evenly in 6 intervals. , 2nd gear - 4 seconds, 3rd gear - 6 seconds, 4th gear - 8 seconds, 5th gear - 10 seconds, 6th gear - 12 seconds.

[0067] The setting switch in the setting module of this embodiment includes a self-resetting button switch and a self-resetting double-speed toggle switch, such as Figure 4 shown.

example 3

[0085] The application of the function expansion switch in the control of the automatic gear of the automobile wiper proposed by the present invention will be described below through the third implementation.

[0086] In this embodiment, in addition to completing the switching between the "automatic intermittent" working state and the "manual intermittent" working state and setting the fixed gap time in the setting module including the above-mentioned one-key operation setting switch, it further includes a function expansion switch, Figure 5 shown.

[0087] By adding a function expansion switch in the setting module, the driver's ability to control the automatic gear of the wiper can be further strengthened, and more adjustment functions can be realized.

[0088] A 4-speed electrical toggle switch is added to the setting module of this embodiment, and the same electrical toggle switch can be set as a switch with different functions by the microprocessor in different working s...

Abstract

The invention discloses an intelligent control method and device for a car windscreen wiper automatic gearshift. The method includes the following steps: manually triggering a setting module to issuea switching signal to a microprocessor; controlling to realize mutual switching between the "manual intermittent" working state and the "automatic intermittent" working state after the microprocessorreceives the switching signal. According to the invention, the "intermittent gear" function of the manual wiper with the traditional fixed intermittent time and the automatic induction wiper functionwith automatic intermittent time can be realized through one key operation and can be switched by one key; according to the invention, the disadvantage of complicated operation caused by equipment oftwo functions is avoided, the use experience is improved, safe driving is guaranteed, besides, the cost in simultaneously equipping two functions is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic control of automobiles, in particular to an intelligent control method and device for automatic shifting of an automobile wiper. Background technique [0002] The wiper is an indispensable electrical device for the car. The driver can make the wiper wiper perform the corresponding wipe operation by selecting different adjustment gears of the wiper to help the driver get a better observation field of view when driving in the rain, thus effectively Ensure driving safety. [0003] As we all know, car wipers are divided into two categories: manual wipers and automatic induction wipers. The function of the "intermittent gear" in the manual wiper adjustment gear is to maintain a pause time interval between two consecutive wipes of the wiper, that is, intermittent. time. In the "intermittent gear" working state, the wiper moves periodically, and each complete wiper movement cycle includes two parts: ...
