Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
To make the objects, technical solutions and advantages of the present application more clear, the following description is made by way of specific embodiments with reference to the accompanying drawings.
Referring to fig. 1, it shows a flowchart of an implementation of a control method for a rearview mirror wiper provided in an embodiment of the present application, and details are as follows:
in step S101, after the switch of the motor of the wiper blade is closed, the position of the wiping mechanism of the wiper blade in the rearview mirror is obtained according to the rotation direction of the motor and the number of pulse signals sent to the motor.
Optionally, the motor of the rearview mirror wiper can be mounted inside the mirror shell.
Optionally, the switch of the motor is controlled to be closed in the following manner: receiving a control signal sent by a user, and closing a switch of a motor according to the control signal; or receiving a sensing signal sent by the raindrop sensor, if the current rainfall of the rearview mirror is judged to be greater than or equal to the preset value according to the sensing signal, closing a switch of the motor, and controlling the rotating speed of the motor according to the current rainfall.
For example, a control switch is provided at the driving position, and the driver can turn on the rearview mirror wiper function through the control switch, that is, close the switch of the motor by receiving a control signal sent by the user, so that the motor starts to rotate according to a preset control strategy.
Or a raindrop sensor is independently arranged at the position of the rearview mirror, or the raindrop sensor is shared with the windscreen wipers of the front windshield and the rear windshield, whether a switch of the motor is closed or not is judged according to a sensing signal of the raindrop sensor, so that the rearview mirror windscreen wiper is automatically opened, and the motor rotates according to a preset control strategy.
The raindrop sensor may also be referred to as a raindrop detection sensor for detecting whether it rains and the magnitude of rainfall. At present, there are capacitance type, resistance type, infrared ray detection type, piezoelectric vibrator type and CCD (Charge-coupled Device) camera raindrop sensor, etc., which can be used to detect the rainfall.
Taking a resistance-type raindrop sensor as an example, the sensor converts different collected rainfalls into voltage signals, obtains corresponding digital signals after analog-to-digital (A/D) conversion, and obtains the current rainfall condition after analyzing and processing the digital signals. According to the current rainfall, the motor is controlled to rotate at different speeds, and a wiping mechanism of the windscreen wiper is driven to wipe rainwater on the mirror surface glass of the rearview mirror at a proper speed, so that the aim of cleaning is fulfilled.
In a possible implementation manner, the rotation angle of the motor in the rotation direction is obtained according to the number of the pulse signals sent to the motor and the step angle with the preset size corresponding to two adjacent pulse signals; obtaining the scraping and brushing angle of the scraping and brushing mechanism in the scraping and brushing direction corresponding to the rotating direction according to the rotating angle of the motor in the rotating direction; and obtaining the position of the scraping and brushing mechanism in the rearview mirror according to the scraping and brushing angle of the scraping and brushing mechanism in the scraping and brushing direction.
The motor currently used for driving the wiper blade to rotate on the vehicle is generally a stepping motor. The middle part of the stepping motor is a rotor which consists of a permanent magnet, and the side of the stepping motor is a stator winding. When a winding of the stator is electrified, an electromagnetic field in one direction is generated, and if the direction of the magnetic field and the direction of the magnetic field of the rotor are not on the same straight line, the magnetic fields of the stator and the rotor generate a torsion force to twist the stator. The magnetic field of the winding is changed in sequence, so that the stepping motor can rotate forwards or backwards, and the speed of the stepping motor can be controlled by changing the time interval of switching the magnetic field.
When the stepping motor receives a pulse signal, the stepping motor is driven to rotate by a fixed angle, namely a stepping angle or a stepping angle, according to a set direction, and the angular displacement is controlled by controlling the number of pulses, so that the aim of accurate positioning is fulfilled. Meanwhile, the pulse frequency can be controlled to control the rotating speed and acceleration of the motor, so that the purpose of speed regulation is achieved.
The stepper motor may be continuously rotated while applying a series of continuous control pulses thereto. When the change of the energization state completes one cycle, the rotor rotates by one pitch.
The positive rotation or the reverse rotation of the motor can be controlled by controlling the rotation phase sequence of the rotor.
When the stepping motor works, 1 pulse is output to the stepping motor every time, the time delay is 1 in the middle of the 1 pulse, the 2 nd pulse is output, each pulse represents a step angle, and when the motor runs, the number of the output pulses is accumulated and calculated, so that the current rotating angle of the motor can be calculated.
Optionally, when the wiping mechanism of the windscreen wiper stops wiping, the wiping mechanism is controlled to stay at a preset position of the rearview mirror. That is, the mirror wiper provided in the embodiment of the present invention has a function of automatically returning to a closed position, and fig. 2 shows a mirror wiper provided in the embodiment of the present invention, for example, automatically returning to an upper edge position of the mirror as shown in fig. 2 after the mirror wiper is closed.
Through presetting the control strategy, after the switch of motor is closed, the control motor reversal, scrape brush mechanism and scrape the brush by from top to bottom from the upper edge of rear-view mirror, through the size of the step angle of two adjacent pulse of presetting the motor and the frequency of sending pulse signal, the slew velocity of control motor, and then the control is scraped brush speed. When the scraping and brushing mechanism reaches the rightmost side of the rearview mirror, the motor is controlled to rotate positively, the scraping and brushing mechanism scrapes brushes from the rightmost side to the top from the bottom, when the scraping and brushing mechanism reaches the upper edge of the rearview mirror, the motor is controlled to rotate reversely, the scraping and brushing mechanism scrapes the brushes … … from the top to the bottom again, and accordingly the scraping and brushing mechanism reciprocates until the rearview mirror windscreen wiper is closed and automatically resets to a preset position, such as the upper edge position of the rearview mirror.
The motor is rotated reversely, and the wiping mechanism wipes the brush from top to bottom. The motor starts to rotate reversely, the number of the pulses sent to the motor is calculated, the number of the pulses is multiplied by the stepping angle between every two adjacent pulses, the reverse rotation angle of the motor can be obtained, the angle of the scraping and brushing mechanism for scraping and brushing from top to bottom is correspondingly calculated according to the reverse rotation angle of the motor, and the position of the scraping and brushing mechanism on the rearview mirror can be obtained.
In step S102, a target length of the wiping mechanism of the wiper blade is determined according to a position of the wiping mechanism in the rearview mirror, and the wiping mechanism is adjusted to the target length.
The length of the wiping mechanism is adjusted according to the position of the wiping mechanism in the rearview mirror. As shown in fig. 2, when the wiping mechanism wipes the mirror surface downward at the position shown in fig. 2, the left position of the mirror surface cannot be wiped, and at this time, the length of the wiping mechanism is increased so that the wiping mechanism can wipe the left position of the mirror surface.
Optionally, the wiping mechanism comprises a wiper blade and a telescopic rod, the wiper is further provided with a cylinder connected with the telescopic rod, and the wiping mechanism is adjusted to a target length and comprises: and controlling the pressure of the air cylinder to adjust the scraping and brushing mechanism to the target length.
The embodiment of the application adjusts the length of the scraping and brushing mechanism and increases the scraping and brushing area of the rearview mirror by acquiring the position of the scraping and brushing mechanism of the rearview mirror windscreen wiper in real time in the rearview mirror.
Fig. 3 shows a flowchart of another implementation method for controlling a rearview mirror wiper provided in an embodiment of the present application, which is detailed as follows:
in step S301, after the switch of the motor of the wiper blade is closed, the position of the wiping mechanism of the wiper blade in the rearview mirror is obtained according to the rotation direction of the motor and the number of pulse signals sent to the motor.
The specific implementation manner of this step can be seen in step S101 in the embodiment corresponding to fig. 1, and details of the embodiment of the present invention are not described again.
In step 302, a region where the wiping mechanism of the wiper is located in the rearview mirror is obtained according to a position of the wiping mechanism of the wiper in the rearview mirror, wherein the mirror surface of the rearview mirror is pre-divided into a plurality of continuous and non-overlapping regions according to a mirror surface shape and a mirror surface size of the rearview mirror, and a length of the wiping mechanism corresponding to the region is preset for any region.
As shown in fig. 4, the mirror surface of the rear view mirror is divided into two continuous non-overlapping areas.
In step 303, the length of the wiping mechanism corresponding to the area where the wiping mechanism is located on the rearview mirror is obtained, and the target length is obtained.
Optionally, in the first region, the wiping mechanism wipes with the first length as a target length, and in the second region, the wiping mechanism wipes with the second length.
The mirror surface of the rearview mirror is divided into a plurality of continuous non-overlapping areas, and the length of the scraping and brushing mechanism corresponding to each area is preset in each area. The preset length of the scraping and brushing mechanism corresponding to the located area is obtained by judging the mechanism where the scraping and brushing mechanism is located, and the preset length is used as the target length for scraping and brushing.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
