The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.
As shown in fig. 1, the method for implementing a full-automatic windscreen wiper is based on control and data transmission functions of a CPU (Central Processing Unit central processing unit) and a BCM (body control module body control module) of the automobile, and the two components are conventional components on the automobile, so that the specific structure, the working principle and the installation position of the components are not repeated, a calculation module and a storage module which are connected are conventionally integrated on the CPU and used for calculating and storing data, the method for implementing the full-automatic windscreen wiper comprises arranging a windage sensor, a timing module, a rainfall sensor, a sensitivity adjusting module and a windscreen wiper motor, wherein the windage sensor is used for detecting the wind resistance of the automobile, the rainfall sensor is used for adjusting the sensitivity of the rainfall sensor, the sensitivity adjusting module is used for driving the windscreen wiper to move, the sensitivity adjusting module can be integrated on the rainfall sensor to implement light weight of the module, the windscreen wiper motor can be a controllable reversing motor, the windage sensor and the timing module are connected with the CPU, the sensitivity adjusting module is simultaneously connected with the CPU and the BCM, and the rainfall sensor and the BCM sensor is connected with the sensor through communication with the sensor LIN (Local interconnect Network).
In the above module, the storage module stores an actual wind speed threshold, the actual wind speed threshold can be set by itself and is led into the storage module, and the value detected by the wind resistance sensor can obtain an actual environment wind speed through the calculation module, specifically, the actual environment wind speed can be calculated by adopting the following formula based on the computer program:
v＝V-v 0
in the formula, F is the apparent vehicle speed v of the automobile measured by a wind resistance sensor 0 The actual wind resistance, C is the air resistance coefficient, ρ is the air density, S is the windward area of the automobile, V is the relative motion speed of the automobile and the air, V 0 For the purpose of displaying the vehicle speed, v is the actual ambient wind speed, wherein F, C, ρ and S can be measured by instruments or obtained from known contents.
Based on the above method, the actual environmental wind speed can be obtained, and based on common knowledge, when the environmental wind speed is higher than a certain value and lasts for a period of time, the actual wind speed threshold value can be judged to be larger in next weather, so that when the calculation module obtains the real-time actual environmental wind speed, the CPU can call the threshold value data in the storage module to be compared with the calculated actual environmental wind speed, when the absolute value of the actual environmental wind speed is higher than the actual wind speed threshold value, the CPU can start the timing module to count time, when the absolute value of the actual environmental wind speed is not higher than the actual wind speed threshold value, the CPU can control the timing module to pause timing, when the absolute value of the actual environmental wind speed is not higher than the actual wind speed threshold value, the timing module pauses the timing (the specific value of the set value can be set by itself, such as 5 min), the timing module pauses the timing time to be cleared for a long time to avoid misjudgment, when the accumulated time is not longer than the set value (the set value is 10 min), the specific value of the accumulation time exceeds the set value, the accumulation time is counted up, the BCM sends a feedback signal to the response module is reset to the sensor when the sensor is started, and the sensor window is reset to the sensor window is started, and the sensor window is turned on after the sensor window is turned off, and the sensor window is turned off. In the above steps, the external environment is sensed based on the wind resistance sensor, and whether the weather is changed or not is judged in an auxiliary way through the timing module, so that whether the rainfall is large or not is judged, and the sensitivity of the sensitivity adjusting module is adjusted to be high in advance, so that the sensitivity of the rainfall induction of the wiper system can be adjusted automatically in advance along with the change of weather, and the automation and the intelligent degree of the wiper system are improved obviously.
It should be noted that, in the above steps, the degree of sensitivity is relatively high, and the degree of sensitivity is low, so that a person skilled in the art can set the degree of sensitivity to be high and the degree of sensitivity to be low according to the requirements of the vehicle.
When the timing time is cleared due to the fact that the timing module pauses overtime, the timing module sends a feedback signal to the CPU, and the CPU keeps the control sensitivity adjusting module in a low sensitivity state after receiving the feedback signal, so that the initialization of the sensitivity adjusting module is realized.
In addition, an automobile acceleration sensor can be arranged on the automobile and connected with the BCM, an acceleration analysis program is arranged in a BCM control program, and the automobile acceleration sensor can also be connected with the BCM through LIN communication;
in the running process of the automobile, when the rainfall sensor senses rainfall and the sensed rainfall reaches a set value, a feedback signal is sent to the BCM, and after the BCM receives the feedback signal, a starting instruction is sent to the wiper motor, so that the automobile wiper starts to move, the rainfall sensor plays a role in activating and starting the wiper motor, and of course, the rainfall sensor can also acquire the rainfall acceleration a in the running process of the automobile 1 And can transmit the rainfall acceleration data to the BCM;
when the automobile is in acceleration running, the automobile acceleration sensor can acquire the running acceleration a of the automobile 2 And can transmit the running acceleration data to the BCM, the rainfall acceleration a can be controlled by the acceleration analysis program in the BCM control program 1 Acceleration a of running 2 And (3) analyzing the change of the rain, so as to judge the rainfall condition at the time, and further accurately adjusting the running speed of the wiper motor according to the rainfall condition.
Specifically, when the running acceleration a 2 In the increasing process, if the rainfall acceleration a 1 Increasing at the same rate of increase or increasing at a greater rate of increase, then this indicates no change or drop in rainfall at that timeIf rain is aggravated, if the rainfall acceleration a 1 Increasing at a smaller increasing rate indicates that the rainfall is weakening at this time, but due to the running acceleration a 2 The rain amount sensed by the automobile is still increased in the increasing process, so that the running speed of the wiper motor can be automatically adjusted and fast through the BCM under all conditions, and the increase of the rain amount caused by the acceleration of the automobile is dealt with;
when the running acceleration a 2 Incremental but rain acceleration a 1 When the automobile is lowered, the rainfall is gradually reduced, and even if the automobile is accelerated, the rainfall sensed by the automobile is still continuously reduced due to the fact that the speed of the rainfall is faster, and at the moment, the running speed of the wiper motor can be automatically slowed down through the BCM so as to adaptively cope with the reduction of the rainfall;
when the running acceleration a 2 If the rainfall acceleration a is kept unchanged 1 The running speed of the wiper motor can be automatically adjusted by BCM because the rainfall perceived by the automobile is still increased due to the increase of the running speed, if the rainfall acceleration a 1 The decreasing state indicates that the rainfall at the moment is gradually decreasing, at the moment, even if the automobile is accelerating, the rainfall sensed by the automobile is still continuously decreasing due to the fact that the speed of the decrease of the rainfall is faster, at the moment, the running speed of the wiper motor can be automatically adjusted through the BCM to adaptively cope with the decrease of the rainfall, and if the rainfall acceleration a 1 When the number of the rain drops increases, the operation speed of the wiper motor can be automatically adjusted and fast through the BCM.
When the rainfall sensor does not sense rainfall, the wiper motor can be automatically closed through the BCM;
the existing method only controls the running speed of the wiper motor according to the change of the vehicle speed or the change of the rainfall sensed by the rainfall sensor, specifically, the faster the vehicle speed is, the faster the running speed of the wiper motor is, the slower the reverse speed is, or the faster the rainfall sensed by the rainfall sensor is, the faster the running speed of the wiper motor is, the slower the reverse speed is, so that the automatic control of the wiper speed to a certain extent can be realized, but the speed is notAccurately, for example, when the vehicle speed is accelerating but the rainfall is rapidly weakening, the induction rainfall of the vehicle is actually decreasing, and if the running speed of the wiper motor is still accelerating at this time, it is unnecessary, in this case, even if the vehicle is accelerating, the running speed of the wiper motor is reduced, the existing automatic control method of the wiper cannot accurately judge the actual induction rainfall of the vehicle, and only the actual induction rainfall of the vehicle is extremely inaccurate through the change of the vehicle speed or the change of the rainfall sensed by the rainfall sensor, but the embodiment of the application judges the actual induction rainfall of the vehicle through the running acceleration a 2 With the rainfall acceleration a 1 The rainfall condition is judged in real time by the bidirectional comparison of the sensor, the sensing rainfall of the vehicle can be judged more specifically and accurately, the wiper motor is automatically controlled according to the sensing rainfall of the vehicle, and the automatic and accurate wiper control can be realized.
When the automobile runs at a constant speed, the running acceleration a of the automobile 2 Zero, at this time if the rainfall acceleration a 1 At the time of decreasing, the rainfall is reduced, the running speed of the wiper motor can be automatically adjusted and slowed down through the BCM, if the rainfall acceleration a 1 At the increment, the rainfall is enhanced at the moment, the running speed of the wiper motor can be automatically adjusted and fast through the BCM, if the rainfall acceleration a 1 The operation speed of the wiper motor is kept unchanged.
When the automobile runs at a reduced speed, the running acceleration a 2 In the case of decreasing, if the rainfall acceleration a 1 Decreasing at the same decreasing speed or decreasing at a larger decreasing speed, it indicates that there is no change in the rainfall at this time or the rainfall is weakening, and the perceived rainfall of the automobile is decreasing as a whole, so that the running speed of the wiper motor can be automatically slowed down by the BCM at this time, and if the rainfall acceleration a 1 The rainfall is enhanced at the moment when the rainfall is decreased at a smaller decreasing speed, and the running speed of the wiper motor can be automatically adjusted by the BCM;
when the running acceleration a 2 If the rainfall acceleration a is kept unchanged 1 Decreasing, the rainfall is weakened at the moment, the running speed of the wiper motor can be automatically regulated by the BCM, and if the rainfall is reducedAcceleration a 1 Increasing gradually, the rainfall is enhanced, the running speed of the wiper motor can be automatically adjusted and fast by the BCM, and if the rainfall acceleration a is 1 The running speed of the wiper motor can be automatically slowed down by the BCM at the moment because the automobile is in a deceleration state and the rain feeling of the automobile is reduced as a whole.
The present embodiment is only for explanation of the present application and is not to be construed as limiting the present application, and modifications to the present embodiment, which may not creatively contribute to the present application as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present application.
