Description

[0002] Wipers, also known as windshield wipers, windshield wipers or windshield wipers, are devices used to scrape off raindrops and dust attached to the windshield of a vehicle. Wipers scrape off raindrops and dust attached to the windshield of a vehicle, which can improve visibility in rainy days and other environments, and increase driving safety.

[0003] When the wipers are in manual mode, the driver may cause the wipers to dry brush due to misoperation, such as mistakenly starting the wipers when it is not raining; or starting the wipers when it is raining and not shutting them off in time after the rain stops. When the wipers are in a dry brushing state for a long time, the load torque of the wiper motor is too large, which may cause the motor to overheat and shorten the motor's operating life. Not only that, when the motor temperature reaches the threshold set by the temperature protector, the wiper will stop working immediately. Since the position of the wiper is random when the motor temperature reaches the threshold set by the temperature protector, the wiper may stop suddenly and block the driver's field of view, thereby affecting driving safety.

[0040] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0042] The vehicle's windshield wipers can work in different speed ranges according to different working gears. Generally speaking, the working gears of the wipers can be divided into stop gear, automatic gear, low speed gear and high speed gear. Among them, the stop gear, low speed gear and high speed gear are usually manually controlled by the driver, which can also be called manual mode; the automatic gear is automatically controlled by the vehicle and can also be called automatic mode. Figure 1 The whole vehicle control schematic diagram of the wiper is shown. Figure 1As shown, the combination switch can correspond to different working gears. The user can select the working gear of the wiper through the combination switch. For example, when the user selects the stop gear, the motor of the wiper does not run and the wiper is in the off state; when the user selects the automatic gear, the wiper is automatically controlled by the vehicle controller according to the preset control rules; when the user selects the low speed gear or the high speed gear, the wiper performs low-speed continuous wiping or high-speed continuous wiping. When the working gear corresponding to the combination switch is the stop gear, the low speed gear or the high speed gear, the vehicle controller can directly adjust the working gear of the wiper to the working gear corresponding to the combination switch. When the working gear of the wiper is the automatic gear, the rain sensor can obtain the current rainfall signal, determine the corresponding working gear of the wiper according to the amount of rainfall and the preset rules, and send the corresponding working gear request to the vehicle controller. The vehicle controller adjusts the working gear of the wiper according to the working gear request sent by the rain sensor.

[0043] When the wipers are in manual mode, the driver may cause the wipers to dry brush due to misoperation, for example, accidentally starting the wipers when it is not raining; or starting the wipers when it is raining and not turning them off in time after the rain stops. When the wipers are in a dry brushing state for a long time, the load torque of the wiper motor is too large, which may cause the motor to overheat and shorten the motor's operating life. In addition, when the motor temperature reaches the threshold set by the temperature protector, the wipers will stop working immediately. Figure 2 The schematic diagram of the working circuit of the wiper is shown in FIG. Figure 2 As shown in the figure, when the motor temperature reaches the threshold set by the temperature protector, for example, when the NTC temperature sensor (Negative Temperature Coefficient Sensor) near the commutator / rotor of the motor detects that the motor temperature reaches 150°C, the temperature switch will be disconnected, thereby disconnecting the working circuit and causing the wiper to fail for a short time; when the motor temperature drops to the safe temperature threshold, the temperature switch will close, and the wiper can work again. Since the position of the wiper is random when the motor temperature reaches the threshold set by the temperature protector, the wiper may suddenly stop and block the driver's field of vision, thus affecting driving safety.

[0044] Based on this, in order to reduce the risk of wiper motor overheating caused by user misoperation, thereby improving the service life of the wiper and the safety of user driving, the inventor has in-depth thinking and cleverly designed a wiper control method, device, equipment, computer storage medium and vehicle.

[0045] The wiper control method provided in the embodiment of the present application, the device executing the method may be a wiper control device, or a partial module in the wiper control device for executing the wiper control method. In the embodiment of the present application, the wiper control method provided in the embodiment of the present application is described in detail by taking the wiper control device executing the wiper control method as an example.

[0046] The wiper control method provided in the embodiment of the present application is first introduced below in conjunction with the accompanying drawings.

[0047] Figure 3 FIG. 1 is a flow chart of a wiper control method provided by an embodiment of the present application. Figure 3 As shown, the wiper control method may specifically include the following steps S110 to S130.

[0048] S110, when the wiper is in a preset working mode, detecting a load signal of the wiper and a first working gear of the wiper.

[0049] In step S110, the preset working mode may include a manual mode, for example, a low speed gear or a high speed gear in the manual mode. The load signal of the wiper may represent a signal related to the motor load of the wiper, for example, the working current, the actual speed, etc. of the wiper. The first working gear of the wiper may represent the gear of the current combination switch.

[0050] S120: Acquire a first rainfall signal.

[0051] In step S120, the first rainfall signal may include a signal for characterizing rainfall intensity. The first rainfall signal may be acquired by a rainfall sensor. As an example, the first rainfall signal may include an optical rainfall signal acquired by an optical rainfall sensor. As another example, the first rainfall signal may also include a capacitive rainfall signal acquired by a capacitive rainfall sensor. As yet another example, the first rainfall signal may also include a visual rainfall signal acquired by a visual sensor.

[0052] S130, when the load signal satisfies the overload judgment condition corresponding to the first working gear and the first rainfall signal satisfies the preset rainfall judgment condition, adjusting the working gear of the wiper to reduce the rotation speed of the wiper.

[0053] In step S130, the overload judgment condition may be a pre-set condition for judging whether the motor load of the wiper is too high. When the wiper is in different working gears, the load that the motor can bear may be different, and the corresponding overload judgment condition may also be different. The preset rainfall judgment condition may be a pre-set condition for judging whether dry brushing may occur in the wiper under the current rainfall signal. In one embodiment, the preset rainfall judgment condition may include that the rainfall intensity corresponding to the first rainfall signal is less than or equal to the preset rainfall intensity threshold. Adjusting the working gear of the wiper may include downshifting the wiper, for example, when the first working gear is a high-speed gear, the working gear of the wiper may be adjusted to a low-speed gear; when the first working gear is a low-speed gear, the working gear of the wiper may be adjusted to an intermittent wiping gear, for example, wiping for 2 seconds intermittently. In one embodiment, intermittent wiping can be achieved by switching the stop gear and the low-speed gear.

[0054] The wiper control method of the embodiment of the present application can detect the load signal of the wiper and the first working gear of the wiper, and obtain the first rain signal when the wiper is in a preset working mode. When the load signal meets the overload judgment condition corresponding to the first working gear and the first rain signal meets the preset rain judgment condition, the working gear of the wiper is adjusted to reduce the speed of the wiper. In this way, it is possible to judge whether the wiper is overloaded according to the current working gear of the wiper and the actual load, and to judge whether the wiper is in a dry brushing state in combination with the currently detected rain signal; when the wiper is in a dry brushing state and the load is too high, the working gear of the wiper can be adjusted to reduce the speed of the wiper. In this way, when the user misoperates the wiper and causes the wiper to dry brush, the embodiment of the present application can timely adjust the speed of the wiper, thereby reducing the risk of overheating of the wiper motor, thereby, on the one hand, the operating life of the wiper can be improved; on the other hand, the probability of the wiper randomly stopping at any position of the windshield can be reduced, thereby improving the safety of the user's driving.

[0055] In one embodiment, the load signal may include an actual rotation speed of the wipers.

[0056] The load signal satisfies the overload judgment condition corresponding to the first working gear, which may specifically include:

[0057] The actual rotation speed is less than or equal to the overload rotation speed threshold corresponding to the first working gear.

[0058] When the wiper is dry brushing, causing the motor load to be greater than the normal working load, the actual speed of the wiper will be lower than the normal speed range corresponding to the current working gear. According to the actual speed of the wiper, it can be determined whether the motor load of the wiper is too high. The above-mentioned overload speed threshold may include an overload speed threshold set according to the working gear. As an example, when the first working gear is a high-speed gear, its corresponding normal speed range can be set to 60±10r / min, and the overload speed threshold can be set to 47r / min. When the first working gear is a low-speed gear, its corresponding normal speed range can be set to 45±10r / min, and the overload speed threshold can be set to 32r / min. In some embodiments, in order to reduce the risk of misjudgment, the average speed of the wiper within 2 minutes, or the average speed of 60 revolutions, can be detected as the actual speed of the wiper.

[0059] According to the actual speed of the wiper and the overload speed threshold corresponding to the first working gear, it is judged whether the load signal of the wiper meets the overload judgment condition, which is conducive to timely discovering the risk of excessive load of the wiper motor. In this way, when the user misoperates the wiper and causes dry brushing of the wiper, the embodiment of the present application can adjust the speed of the wiper in time, thereby reducing the risk of overheating of the wiper motor, thereby, on the one hand, prolonging the service life of the wiper; on the other hand, it can reduce the probability of the wiper randomly stopping at any position of the windshield, thereby improving the safety of the user's driving.

[0060] In one embodiment, the load signal may include an operating current of a wiper.

[0061] The load signal satisfies the overload judgment condition corresponding to the first working gear, which may specifically include:

[0062] The operating current is greater than or equal to the overload current threshold corresponding to the first operating gear.

[0063] When the wiper is dry brushing, causing the motor load to be greater than the normal working load, the wiper's operation will be higher than the normal current range corresponding to the current working gear. According to the working current of the wiper, it can be determined whether the motor load of the wiper is too high. The above-mentioned overload current threshold may include an overload current threshold set according to the working gear. As an example, when the first working gear is a high-speed gear, its corresponding normal current range can be set to 4±3A, and the overload current threshold can be set to 7A. When the first working gear is a low-speed gear, its corresponding normal current range can be set to less than 1A, and the overload current threshold can be set to 1A. In some embodiments, in order to reduce the risk of misjudgment, the average working current of the wiper within 2 minutes can be detected as the working current of the wiper.

[0064] According to the working current of the wiper and the overload current threshold corresponding to the first working gear, it is judged whether the load signal of the wiper meets the overload judgment condition, which is conducive to timely discovering the risk of excessive load of the wiper motor. In this way, when the user misoperates the wiper and causes dry brushing of the wiper, the embodiment of the present application can adjust the speed of the wiper in time, thereby reducing the risk of overheating of the wiper motor, thereby, on the one hand, prolonging the service life of the wiper; on the other hand, it can reduce the probability of the wiper randomly stopping at any position of the windshield, thereby improving the safety of the user's driving.

[0065] In one embodiment, after acquiring the first rainfall signal, the method may further include:

[0066] According to a preset rule, a second working gear corresponding to the first rainfall signal is determined.

[0067] The first rainfall signal satisfies a preset rainfall judgment condition, which may specifically include: the second working gear corresponding to the first rainfall signal is a preset gear.

[0068] The preset rule may be a corresponding relationship between the rain signal and the working gear, which is set according to the relationship between the rain intensity corresponding to the rain signal and the speed required for the wiper to wipe off the rain attached to the windshield at the rain intensity. The preset gear may include an intermittent wiping gear and a stop gear. When the second working gear corresponding to the first rain signal is the preset gear, it can be considered that the current rainfall is small or there is no rain, and there is a risk of dry wiping of the wiper.

[0069] Generally speaking, when the wiper is in automatic mode, the rain sensor can obtain the current rainfall signal, determine the corresponding working gear of the wiper according to the rainfall intensity and preset rules, and send the corresponding working gear request to the vehicle controller. The vehicle controller can adjust the working gear of the wiper according to the working gear request sent by the rain sensor. When the wiper is in manual mode, the rain sensor will not be enabled.

[0070] The above embodiment can enable the rain sensor when the wiper is in manual mode, and judge whether the wiper has a risk of dry brushing according to the second working gear corresponding to the first rain signal. In this way, on the one hand, the utilization rate of the rain sensor can be improved, and the risk of dry brushing of the wiper can be judged without adding other equipment; on the other hand, the accuracy of the dry brushing judgment of the wiper can be improved. In this way, when the user misoperates the wiper and causes the wiper to dry brush, the embodiment of the present application can adjust the speed of the wiper in time, thereby reducing the risk of overheating of the wiper motor. Therefore, on the one hand, the service life of the wiper can be improved; on the other hand, the probability of the wiper randomly stopping at any position of the windshield can be reduced, thereby improving the safety of the user's driving.

[0071] In one embodiment, after adjusting the working position of the wiper, the method may further include:

[0072] Acquire a second rainfall signal.

[0073] According to a preset rule, a third working gear corresponding to the second rainfall signal is determined.

[0074] When the second rainfall signal does not meet the preset rainfall judgment condition, the gear position of the wiper is adjusted to the third working gear position.

[0075] In this embodiment, the preset rules may be as described above and are not described in detail here. When the second rainfall signal does not meet the preset rainfall judgment condition, it can be considered that the current rainfall intensity is high and low-speed continuous scraping or high-speed continuous scraping is required. In one embodiment, the second rainfall signal does not meet the preset rainfall judgment condition, which may include: the third working gear corresponding to the second rainfall signal is not the preset gear described above.

[0076] The above embodiment can adjust the gear of the wiper to the working gear corresponding to the second rain signal when the rainfall intensity is high. In this way, the speed of the wiper can be increased when the rainfall is heavy. This is conducive to improving the efficiency of the wiper in scraping rainwater off the windshield surface, thereby helping to improve the flexibility of wiper control and the safety of driving in rainy days.

[0077] In one embodiment, after adjusting the working position of the wiper, the method may further include:

[0078] A gear adjustment instruction sent by a user device is received, where the gear adjustment instruction includes target working gear information.

[0079] The working gear of the wiper is adjusted according to the target working gear information.

[0080] In this embodiment, the working position of the wiper can be adjusted according to the user's instructions. In this way, in the face of special circumstances, such as when the wiper is misjudged as dry brushing or in dusty weather, the speed of the wiper can be adjusted according to the user's needs. In this way, the flexibility of wiper control and driving safety can be further improved.

[0081] Based on the same inventive concept, an embodiment of the present application also provides a wiper control device.

[0082] like Figure 4 As shown, the wiper control device 200 may include a detection module 201 , an acquisition module 202 and an adjustment module 203 .

[0083] The detection module 201 is used to detect the load signal of the wiper and the first working gear of the wiper when the wiper is in a preset working mode.

[0084] The acquisition module 202 is used to acquire a first rainfall signal.

[0085] The adjustment module 203 is used to adjust the working gear of the wiper to reduce the rotation speed of the wiper when the load signal meets the overload judgment condition corresponding to the first working gear and the first rainfall signal meets the preset rainfall judgment condition.

[0086] The wiper control device of the embodiment of the present application can detect the load signal of the wiper and the first working gear of the wiper, and obtain the first rain signal when the wiper is in a preset working mode. When the load signal meets the overload judgment condition corresponding to the first working gear and the first rain signal meets the preset rain judgment condition, the working gear of the wiper is adjusted to reduce the speed of the wiper. In this way, it is possible to judge whether the wiper is overloaded according to the current working gear of the wiper and the actual load, and to judge whether the wiper is in a dry brushing state in combination with the currently detected rain signal; when the wiper is in a dry brushing state and the load is too high, the working gear of the wiper can be adjusted to reduce the speed of the wiper. In this way, when the user misoperates the wiper and causes the wiper to dry brush, the embodiment of the present application can timely adjust the speed of the wiper, thereby reducing the risk of overheating of the wiper motor, thereby, on the one hand, the operating life of the wiper can be improved; on the other hand, the probability of the wiper randomly stopping at any position of the windshield can be reduced, thereby improving the safety of the user's driving.

[0087] In one embodiment, the load signal may include an actual rotation speed of the wipers.

[0088] The load signal satisfies the overload judgment condition corresponding to the first working gear, which may specifically include:

[0089] The actual rotation speed is less than or equal to the overload rotation speed threshold corresponding to the first working gear.

[0090] In one embodiment, the load signal may include an operating current of a wiper.

[0091] The load signal satisfies the overload judgment condition corresponding to the first working gear, which may specifically include:

[0092] The operating current is greater than or equal to the overload current threshold corresponding to the first operating gear.

[0093] In one embodiment, the apparatus may further include:

[0094] The determination module is used to determine the second working gear corresponding to the first rainfall signal according to a preset rule.

[0095] The first rainfall signal satisfies a preset rainfall determination condition, including: the second working gear corresponding to the first rainfall signal is a preset gear.

[0096] In one embodiment, the apparatus may further include:

[0097] The acquisition module is used to acquire a second rainfall signal.

[0098] The determination module is used to determine the third working gear corresponding to the second rainfall signal according to a preset rule.

[0099] The adjustment module is used to adjust the gear position of the wiper to a third working gear position when the second rainfall signal does not meet the preset rainfall judgment condition.

[0100] In one embodiment, the apparatus may further include:

[0101] The receiving module is used to receive a gear adjustment instruction sent by a user device, where the gear adjustment instruction includes target working gear information.

[0102] The adjustment module is used to adjust the working gear of the wiper according to the target working gear information.
