Fig. 1 is a flowchart of a wiper adjustment control method according to an embodiment of the present invention.
Detailed Description
The following description of embodiments refers to the accompanying drawings, which illustrate specific embodiments in which the invention may be practiced.
When the vehicle leaves the factory, the mapping relation between the triggering signal and the control parameter of the vehicle wiper is calibrated and obtained in advance and stored in the vehicle. When a triggering signal of the wiper is detected in the running process of the vehicle, the control of the wiper is triggered, and corresponding control parameters can be obtained based on the mapping relation stored in the vehicle; and then according to a wiper control algorithm, a wiper control output is obtained by the trigger signal and corresponding control parameters, so as to control the movement of the wiper. On the basis, the embodiment of the invention can receive the adjustment instruction of a user on the windscreen wiper, adjust the control parameters of the windscreen wiper of the vehicle according to the adjustment instruction, obtain the control output of the windscreen wiper by combining the adjusted control parameters with the trigger signal, and adjust and control the movement of the windscreen wiper, thereby better meeting the use requirement of the user.
As shown in fig. 1, the method for controlling adjustment of a wiper according to the embodiment of the present invention specifically includes the following steps:
s10, when the control of the windscreen wiper is triggered, acquiring control parameters of the windscreen wiper;
specifically, during the running of the vehicle, a trigger signal of the vehicle wiper is detected, and when the trigger signal of the wiper is detected, the wiper control is triggered. When the wiper control is triggered, the wiper control parameters are acquired. The wiper control parameter is a prestored control parameter corresponding to the trigger signal.
And after the wiper control parameters are obtained, controlling the wiper to move according to the wiper control parameters.
The trigger signal may include at least: the current rainfall of the wiping area, the current speed of the vehicle and the gear. In one embodiment, the trigger signal for the vehicle wiper includes the current amount of rain in the wiping area, the current speed of the vehicle, and the gear. At the beginning of the use of the windscreen wiper (for example, when the vehicle leaves a factory), the mapping relation among different rainfall, vehicle speed, gear and various control parameters is calibrated and obtained in advance and stored in the vehicle. When the triggering signal of the current vehicle windscreen wiper is detected, the control parameters corresponding to the triggering signal can be obtained according to the stored mapping relation, and then the windscreen wiper control output is obtained by combining a windscreen wiper control algorithm, so that the movement of the windscreen wiper is controlled.
In one embodiment, the wiper control algorithm may be expressed as:
FO＝f(r,v,g)＝a*r+b(v,g)
FO is wiper control output, r is rainfall, v is vehicle speed, g is vehicle gear, and a and b are control parameters. When the vehicle leaves the factory, calibrating a plurality of groups of control parameters a and b in advance, and establishing a mapping relation between the control parameters a and b and the rainfall r, the vehicle speed v and the vehicle gear g. For example, 4 sets of control parameters [ a0, b0], [ a1, b1], [ a2, b2], [ a3, b3] may be calibrated in advance, corresponding to the 4 speed intervals v0, v1, v2, v3, respectively, that is, the values of the control parameters a, b may be determined jointly by the vehicle speed and the vehicle gear. This is merely an example, and is used to illustrate the correspondence between the trigger signal and the control parameter in the embodiment of the present invention, and the specific calibration method and mapping relation are not limited thereto.
The wiper control output FO may be mapped to a movement speed of the wiper, for example, for a two-stage wiper having only a high speed and a low speed, the wiper control output FO may be mapped to a stop, a low speed continuous wiper, or a high speed continuous wiper; for infinitely variable speed wipers, the wiper control output FO map may be a stop or a different speed of movement.
In an embodiment, a triggering signal of a vehicle wiper is detected, wherein the current amount of rain of the wiping area may be obtained by a rain sensor or an image recognition technique. Further, when the current rainfall of the scraping area is obtained, a rainfall signal which can accurately and objectively reflect the rainfall can be obtained through vehicle speed compensation and ambient light compensation.
And S11, if an adjustment instruction of a user for the windscreen wiper is received, adjusting the windscreen wiper control parameters according to the adjustment instruction to obtain adjusted control parameters, and controlling the windscreen wiper to move according to the adjusted control parameters.
The adjusting instruction at least comprises a quick adjusting windscreen wiper or a slow adjusting windscreen wiper. When the received adjustment instruction is to adjust the windscreen wiper, adjusting the windscreen wiper control parameters according to a preset adjustment strategy, so that the movement speed of the controlled windscreen wiper can be increased from an initial speed to a higher speed; when the received adjustment command is to slow down the wiper, the wiper control parameter is adjusted according to a preset adjustment strategy, so that the movement speed of the control wiper can be reduced from an initial speed to a lower speed.
According to the embodiment of the invention, the adjustment instruction of the user on the windscreen wiper can be received in a voice recognition mode or in a mode of responding to the operation of the virtual switch of the windscreen wiper by the user. For example, when a user feeds back a "quick point" through voice, the embodiment of the invention obtains an adjustment instruction for adjusting the wiper through voice recognition; when a user feeds back a little slow through voice, the embodiment of the invention obtains an adjustment instruction for slowing down the windscreen wiper through voice recognition.
Further, before receiving an adjustment instruction of a user for the windscreen wiper, the embodiment of the invention may further include: the user is identified by at least one identification mode of a user key, facial identification and voiceprint identification. And acquiring an adjustment instruction from the user on the basis of identifying the user.
Further, in an embodiment, in the set time after the movement of the wiper is controlled according to the adjusted control parameter, if the adjustment instruction of the user for the wiper is continuously received, the step of adjusting the wiper control parameter according to the adjustment instruction to obtain the adjusted control parameter and controlling the movement of the wiper according to the adjusted control parameter is repeatedly executed.
Specifically, when an adjustment instruction from a user is received to speed up the wiper, the wiper control parameter is adjusted with a predetermined adjustment policy, and the movement speed of the wiper can be controlled to be increased from the initial speed to the second speed. If the adjustment instruction from the user is continuously received in the set time after the windscreen wiper is controlled to move at the second speed, the current windscreen wiper control parameter is continuously adjusted on the basis of the adjusted windscreen wiper control parameter, which may include: when receiving an adjustment instruction for adjusting the windscreen wiper from a user, continuing adjusting the windscreen wiper control parameter, and controlling the movement speed of the windscreen wiper to be increased from the second speed to the third speed; and when an adjustment instruction for slowing down the windscreen wiper is received from a user, continuing to adjust the windscreen wiper control parameter, and controlling the movement speed of the windscreen wiper to be reduced from the second speed to a fourth speed, wherein the fourth speed is larger than the initial speed. And so on.
When an adjustment instruction from a user is received to slow down the wiper, the wiper control parameter is adjusted according to a preset adjustment strategy, so that the movement speed of the wiper can be controlled to be reduced from an initial speed to a fifth speed. If the adjustment instruction from the user is continuously received within the set time after the wiper is controlled to move at the fifth speed, the current wiper control parameter is continuously adjusted on the basis of the adjusted wiper control parameter, which may include: when an adjustment instruction for slowing down the windscreen wiper is received from a user, continuing to adjust windscreen wiper control parameters, and controlling the movement speed of the windscreen wiper to be reduced from a fifth speed to a sixth speed; when an adjustment instruction for adjusting the windscreen wiper is received from a user, continuing to adjust the windscreen wiper control parameters, and controlling the movement speed of the windscreen wiper to be increased from a fifth speed to a seventh speed, wherein the seventh speed is smaller than the initial speed. And so on.
The control parameters a, b are described above as examples, and the initial values of the control parameters a, b are [ a, b ], where the initial values of the control parameters a, b are one of 4 sets of control parameters [ a0, b0], [ a1, b1], [ a2, b2], [ a3, b3] calibrated in advance, that is, the vehicle is controlling the movement of the wiper according to the wiper control parameters [ a, b ].
When receiving an adjustment instruction of the quick-adjusting windscreen wiper from a user, adjusting windscreen wiper control parameters a and b according to a preset adjustment strategy and enabling the windscreen wiper control parameters a and b to be changed from initial values [ a, b ]]Adjusted to a first value [ a+x ] 1 ,b+y 1 ]So that the wiper control output FO increases and the movement speed of the control wiper increases from the initial speed to the second speed. If the adjustment instruction of the quick-adjusting windscreen wiper from the user is continuously received, the windscreen wiper control parameter is continuously adjusted, and is controlled by a first value [ a+x ] 1 ,b+y 1 ]Adjusted to a second value [ a+3x ] 1 ,b+3y 1 ]So that the wiper control output FO continues to increase while the movement speed of the control wiper increases from the second speed to the third speed. However, if an adjustment instruction for slowing down the wiper is received from the user, the wiper control parameter is continuously adjusted to be a first value [ a+x ] 1 ,b+y 1 ]Adjusted to a third value of [ a+0.5x ] 1 ,b+0.5y 1 ]The wiper control output FO is reduced and the movement speed of the control wiper is reduced from the second speed to a fourth speed, which is greater than the initial speed.
When receiving an adjustment instruction for slowing down the wiper from a user, adjusting the wiper control parameters a and b according to a preset adjustment strategy to obtain initial values [ a, b ]]Adjusted to a fourth value [ a-x ] 2 ,b-y 2 ]So that the wiper control output FO is lowered and the movement speed of the control wiper is lowered from the initial speed to the fifth speed. If the adjustment instruction of the slow down windscreen wiper from the user is continuously received, the windscreen wiper control parameter is continuously adjusted, and is changed from a fourth value [ a-x ] 2 ,b-y 2 ]Adjusted to a fifth value [ a-3x ] 2 ,b-3y 2 ]So that the wiper control output FO continues to decrease and the movement speed of the control wiper decreases from the fifth speed to the sixth speed. However, if the adjustment command of the quick-adjusting wiper is received from the user, the wiper control parameter is continuously adjusted to be a fourth value [ a-x ] 2 ,b-y 2 ]Adjusted to a sixth value [ a ]0.5x 2 ,b-0.5y 2 ]The wiper control output FO is increased and the movement speed of the wiper is controlled to increase from the fifth speed to a seventh speed, at which time the seventh speed is less than the initial speed.
Specific adjustment amounts such as x 1 、y 1 、x 2 、y 2 May be determined by the adjustment strategy.
And S12, storing the adjusted control parameters as the wiper control parameters.
Specifically, after the adjustment of the control parameters is completed according to the adjustment instruction of the user on the windscreen wiper, the adjusted control parameters are stored as the windscreen wiper control parameters. Storing the adjusted control parameter as the wiper control parameter means storing the adjusted control parameter and replacing the control parameter corresponding to the detected trigger signal, that is, replacing the control parameter corresponding to the trigger signal with the adjusted control parameter in the mapping relation stored in the vehicle.
In one embodiment, whether the adjustment is completed may be determined by determining whether a subsequent adjustment instruction is received within a set time. That is, if the subsequent adjustment command is not received within the set time after the movement of the wiper is controlled according to the adjusted control parameter, the current round adjustment of the control parameter is determined to be completed. And if the adjustment instruction from the user is continuously received within the set time, continuously and repeatedly executing the steps of adjusting the wiper control parameters according to the adjustment instruction, obtaining adjusted control parameters and controlling the wiper to move according to the adjusted control parameters. It appears that a round of adjustment of the control parameter may comprise only one adjustment of the control parameter, or may comprise multiple adjustments of the control parameter.
And after finishing the adjustment, storing the control parameters after the last adjustment as the wiper control parameters.
For example, when receiving an adjustment instruction for adjusting the wiper from the user, the wiper control parameters a, b are changed from initial values [ a, b ] according to a predetermined adjustment strategy]Adjusted to a first value [ a+x ] 1 ,b+y 1 ]After that, if the time is setThe subsequent adjustment instruction is not received, the first value [ a+x ] 1 ,b+y 1 ]For the last adjusted control parameter, a first value [ a+x ] is saved 1 ,b+y 1 ]Replace the initial value [ a, b ]]As control parameters a, b corresponding to the trigger signal. For another example, when receiving an adjustment command from a user to slow down the wiper, the current control parameters a, b are changed from initial values [ a, b ] according to a predetermined adjustment strategy]Adjusted to a fourth value [ a-x ] 2 ,b-y 2 ]Then, if the subsequent adjustment command is not received within the set time, the fourth value [ a-x ] 2 ,b-y 2 ]For the last adjusted control parameter, a fourth value [ a-x ] is saved 2 ,b-y 2 ]Replace the initial value [ a, b ]]As control parameters a, b corresponding to the trigger signal.
After the control parameters corresponding to the trigger signals in the mapping relation stored in the vehicle are replaced by the control parameters after the last adjustment in the current wheel adjustment, when the windscreen wiper is started again or the adjustment control on the windscreen wiper is started again, the prestored control parameters corresponding to the trigger signals are the replaced control parameters, namely the control parameters after the last adjustment.
Thus, the embodiment of the invention not only can dynamically adjust the control parameters of the windscreen wiper according to the use requirement of a user and control the movement of the windscreen wiper; the adjustment result satisfying the user can be stored, so that when the user starts the wiper again, the wiper is controlled to directly operate in a mode suitable for the user, and even if the user changes the wiper, the control parameters of the wiper can still correspond to the stored control parameters without long-time adjustment again.
Further, because the embodiment of the invention can identify the user, the embodiment of the invention can obtain the control parameter after the last adjustment after the adjustment is completed, store the control parameter after the last adjustment under the account of the user and replace the control parameter corresponding to the trigger signal. That is, the control parameters stored under the user account are updated, and the control parameters corresponding to the trigger signals are replaced by the control parameters after the last adjustment. In this way, when the wiper is opened again, the user can control the movement of the wiper according to the updated control parameters stored in the user account by identifying the user.
