At present, differential pressure sensors, ultrasonic sensors, image sensors, etc. are usually used to measure the wading depth. However, the differential pressure sensor needs to be immersed in water to measure, which requires the differential pressure sensor to be set as low as possible from the vehicle chassis.

[0031] 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 configured to explain the present application and are not configured 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.

[0032] 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 existence of other identical elements in the process, method, article or device including the elements.

[0033] Due to climate change and other reasons, the probability of extreme weather is increasing, including rain disasters. In rain disasters, water often accumulates due to excessive precipitation. When a vehicle passes through the accumulated water, the vehicle is often damaged because the water level is too deep. In order to avoid the problem of vehicle damage caused by the user's inability to know the depth of accumulated water in time, differential pressure sensors, ultrasonic sensors, image sensors, etc. are used in the prior art to measure the wading depth. However, the above-mentioned measurement methods cannot meet the needs of users due to their own defects.

[0034] In order to solve the problems of the prior art, embodiments of the present application provide a vehicle wading depth measurement system, a vehicle, a method, an apparatus, an electronic device and a storage medium.

[0035] The following first introduces the vehicle wading depth measurement system provided in the embodiment of the present application.

[0036] like Figure 1 As shown, the vehicle wading depth measurement system includes:

[0037] N resistor units 20 are arranged on the wheel 10, each resistor unit 20 includes a resistor 2041, a first contact 2042, and a second contact 2043, the resistor 2041 is electrically connected to the first contact 2042, the first contact 2042 is electrically isolated from the second contact 2043, and both the first contact 2042 and the second contact 2043 are in contact with the outside, wherein N is an integer greater than or equal to 1;

[0038] A control module 30 disposed on the wheel 10 , electrically connected to the N resistance units 20 , and used to obtain resistance parameters of the N resistance units 20 ;

[0039] The wireless receiving device 40 is connected to the control module 30 for communication, and is used for signal connection with at least one of the vehicle controller and the user terminal.

[0040] The control module 30 and the N resistor units 20 basically form a measurement circuit of the vehicle wading depth measurement system. The control module 30 can be electrically connected to the N resistor units 20 through the first measurement point 202 and the second measurement point 203. In the measurement circuit, except for the first contact 2042 and the second contact 2043, all other components are insulated and waterproof.

[0041] Since the first contact 2042 is electrically isolated from the second contact 2043, both the first contact 2042 and the second contact 2043 are in contact with the outside world. Therefore, when the wheel 10 is not in a wading state, the first contact 2042 and the second contact 2043 are not conductive. When the wheel 10 is in a wading state, the first contact 2042 and the second contact 2043 can be conductive through water.

[0042] When the wheel 10 is wading, the first contact 2042 and the second contact 2043 in the resistance unit 20 are connected by water, causing the resistance value to change. The control module 30 can obtain the resistance parameters corresponding to the resistance value change through the first measuring point 202 and the second measuring point 203, and then estimate the wading depth based on the obtained resistance parameters.

[0043] The execution subject of estimating the wading depth according to the resistance parameter can be the control module 30 or the vehicle, such as the vehicle controller. For the former, the control module 30 can be a resistance tester with computing capability or a chip with resistance measurement capability, such as a microcontroller. After obtaining the resistance parameter, the control module 30 can estimate the wading depth according to the resistance parameter, and transmit the water depth signal corresponding to the wading depth to the wireless receiving device 40 through wireless communication (such as Bluetooth, wifi, etc.). After receiving the water depth signal, the wireless receiving device 40 can transmit the water depth signal to the vehicle controller of the vehicle so that the vehicle controller executes the corresponding control strategy according to the water depth signal, and can also transmit the signal to the user terminal, such as the vehicle terminal, the vehicle UI device, the mobile terminal paired with the vehicle (such as the user's mobile phone), etc., to output the water depth information to the user, such as the driver. For the latter, after obtaining the resistance parameter, the control module 30 can transmit the resistance parameter to the wireless receiving device 40 through wireless communication. After receiving the resistance parameter, the wireless receiving device 40 may transmit the resistance parameter to the vehicle controller, and the vehicle controller estimates the wading depth according to the acquired resistance parameter.

[0044] In the embodiment of the present application, by setting the resistance unit 20 and the control module 30 on the wheel 10, when the vehicle wades, the first contact 2042 and the second contact 2043 of the resistance unit 20 submerged in water can be connected by water, so that the control module 30 obtains the corresponding resistance parameter. Since the resistance parameter is related to the wading depth, the wading depth can be calculated according to the obtained resistance parameter. It can be seen that the embodiment of the present application can well realize the measurement of the wading depth of the vehicle.

[0045] When the vehicle is wading, water is likely to remain on the wheel surface, and the residual water may cause the first contact point 2042 and the second contact point 2043 to be misconnected when they are not submerged.

[0046] In view of this, in some embodiments, a water-blocking layer may be provided on the wheel surface between the first contact 2042 and the second contact 2043, or the first contact 2042 and the second contact 2043 may be appropriately protruded from the wheel surface, and an insulating layer or a water-blocking layer may be provided on the side surfaces of the first contact 2042 and the second contact 2043. By the above arrangement, it is possible to avoid miscommunication between the first contact 2042 and the second contact 2043 in a non-submerged state, thereby improving the accuracy of the measurement.

[0047] In some embodiments, Figure 2 As shown, the control module 30 includes a controller 31 and a wireless transmitting device 32, wherein the controller 31 is electrically connected to N resistor units 20 for obtaining resistance parameters of the N resistor units 20; the wireless transmitting device 32 is signal-connected to the controller 31 and is communicatively connected to the wireless receiving device 40.

[0048] In the embodiment of the present application, the number of the resistance units can be either multiple or one. These two implementation modes are described in detail below.

[0049] In some embodiments, Figure 3 As shown, the number of the resistance units 20 is multiple, that is, N is greater than 1, and the N resistance units 20 are arranged at intervals along the circumference of the wheel 10. The N resistance units 20 are electrically connected to the control module 30 after being connected in parallel. The control module 30 is used to obtain the resistance values ​​of the N resistance units 20.

[0050] In addition, the N resistance units 20 may also be arranged at intervals along a straight line on the wheel 10 , which is easy to understand and will not be described in detail.

[0051] The control module 30 and the N resistor units 20 basically form a measurement circuit of the vehicle wading depth measurement system. In the measurement circuit, each resistor unit 20 is connected to the first measurement point 202 and the second measurement point 203 in parallel, and the control module 30 is electrically connected to the first measurement point 202 and the second measurement point 203. Specifically, in each resistor unit 20, the resistor 2041 is electrically connected to the first contact 2042 and the first measurement point 202, the second contact 2043 is electrically connected to the second measurement point 203, the first contact 2042 is electrically isolated from the second contact 2043, and the first contact 2042 and the second contact 2043 are both in contact with the outside world.

[0052] In this embodiment, when the first contact 2042 and the second contact 2043 of any number of the resistor units 20 are connected, the entire measurement circuit is in a conducting state, and a corresponding resistance value is generated between the first measurement point 202 and the second measurement point 203. Moreover, the more the number of resistor units 20 that are connected is, the smaller the resistance value generated between the first measurement point 202 and the second measurement point 203 is.

[0053] When the wheel 10 is wading, the first contact 2042 and the second contact 2043 in the resistance unit 20 are connected by water, so that the resistance value between the first measuring point 202 and the second measuring point 203 changes, so that the number of wading resistance units 20 can be determined according to the resistance value between the first measuring point 202 and the second measuring point 203. Since the wading depth is positively correlated with the number of wading resistance units 20, the wading depth can be determined according to the number of wading resistance units 20.

[0054] In some embodiments, the control module 30 is further configured to:

[0055] estimating the flooded quantity of the resistance unit 20 according to the resistance value;

[0056] The wading depth of the vehicle is estimated based on the arrangement parameters of the N resistance units 20 on the wheel 10 and the number of submerged wheels.

[0057] In this embodiment, the control module 30 is electrically connected to the first measuring point 202 and the second measuring point 203, and can obtain or detect the resistance value between the first measuring point 202 and the second measuring point 203, and can calculate the corresponding wading depth through the resistance value. When the wheel is wading, the first contact 2042 and the second contact 2043 in the resistance unit 20 are connected through water, and the control module 30 can measure the resistance at the first measuring point 202 and the second measuring point 203, and determine the number of wading resistance units 20 according to the measured resistance value, and then estimate the wading depth, and then generate a water depth signal according to the wading depth.

[0058] In some embodiments, the resistance value of the resistor 2041 of each resistor unit 20 is equal and much larger than the resistance value of water.

[0059] Therefore, setting the resistance of each resistor unit 20 to an equal resistance value can make the corresponding relationship between the resistance value of the measurement circuit and the wading depth more accurate. Setting the resistance of the resistor 2041 to be much larger than the resistance of water can avoid the small difference between the resistance of water and the resistance of the resistor 2041, which will have a greater impact on the resistance 2041 of the measurement circuit. In summary, setting the resistance 2041 of the resistor unit 20 to an equal resistance value and much larger than the resistance of water can make the measurement of the wading depth more accurate.

[0060] In some embodiments, Figure 3 As shown, the wheel 10 generally includes a tire 101 and a hub 102 , and N resistance units 20 may be disposed on the hub 102 of the wheel 10 .

[0061] In this embodiment, the N resistor units 20 can be arranged on the outside of the hub 102 of the wheel 10, or on the inside of the hub 102. The N resistor units 20 can be arranged on the hub 102 of the wheel 10 by a fixed setting or an installed setting. The fixed setting may include at least one of welding fixing, screw fixing or steel plate fixing, and the installed setting may include at least one of snap-on installation, key connection installation or adhesive installation. Exemplarily, the N resistor units 20 can be fixed on a PCB board or a plastic part, and then the PCB board or the plastic part can be arranged on the hub 102 by a fixed setting or an installed setting.

[0062] Therefore, by setting N resistor units 20 on the wheel hub, on the one hand, since the structural strength of the wheel hub is relatively stable, it can be ensured that the measurement circuit remains in a stable state, thereby ensuring the stability and reliability of the measurement circuit; on the other hand, the wheel hub will not directly contact the road surface, and under the buffering effect of the tire, the vibration of the wheel hub is greatly reduced, and the wheel hub is generally concave relative to the tire, thereby ensuring the safety of the measurement circuit; on the other hand, when the accumulated water is shallow and has not overflowed the tire, the impact of the accumulated water on the vehicle can be basically ignored, and when the accumulated water overflows the tire and reaches the wheel hub, the measurement circuit can timely measure the wading depth, thereby ensuring the timeliness of the wading depth measurement.

[0063] In some embodiments, Figure 4 As shown, a plurality of resistor units 20 are arranged at intervals on the rim of the hub 102 along the circumference of the hub 102 .

[0064] Thus, by arranging multiple resistor units on the rim closer to the tire, the wading depth of the vehicle can be measured when the wading depth is shallow, and by arranging multiple resistor units circumferentially on the rim of the wheel hub, at least one resistor unit is located on the side close to the driving road surface regardless of the angle at which the wheel is traveling, and thus, the wading depth of the vehicle can be accurately measured regardless of the angle at which the wheel is traveling. Therefore, arranging multiple resistor units on the rim of the wheel hub 102 at intervals along the circumference of the wheel hub 102 can enable the measurement circuit to measure the wading depth more accurately.

[0065] In some embodiments, the resistor units 20 are arranged at equal intervals on the rim.

[0066] As an example, N resistor units 20 are arranged at equal intervals on the rim, the radius of the tire 101 is r1, the radius of the circle formed by the resistor units 20 arranged at equal intervals is r2, and the resistance value of the resistor unit 20 is R. At this time, the calculation method of the wading depth can be shown in Table 1:

[0067] Table 1

[0068]

[0069]

[0070] Thus, by arranging multiple resistance units at equal intervals on the wheel hub, the number of resistance units wading through water can be equal at the same water level regardless of the angle at which the wheel is traveling. Furthermore, since the number of resistance units wading through water is equal, the measured resistance values ​​are also equal. Therefore, during vehicle driving, regardless of the angle at which the wheel is traveling, the resistance value detected by the controller can accurately correspond to the number of resistance units wading through water and the depth of wading through water. Therefore, arranging multiple resistance units at equal intervals on the wheel hub can make the wading depth measured by the measurement circuit more accurate.

[0071] In some embodiments, Figure 4 As shown, the first measuring point 202 and the second measuring point 203 may be located in a central area of ​​the hub 102 .

[0072] Setting the measuring point in the center area of ​​the wheel hub 102 can ensure that the measuring point is located away from the road surface on which the vehicle is traveling, regardless of the angle at which the wheel 10 travels. When the vehicle is wading, the probability of the measuring point wading can be further reduced. Furthermore, the risk of the controller measuring the resistance inaccurately due to the measuring point wading can be reduced.

[0073] In addition, setting the first measuring point 202 and the second measuring point 203 in the central area of ​​the hub 102 helps to keep the electrical connection distance between each resistor unit 20 and the measuring point balanced, and can optimize the circuit structure of the measuring circuit. In particular, when each resistor unit 20 is arranged at intervals along the circumference of the hub 102, the distance between each resistor unit 20 and the measuring point is substantially the same.

[0074] In some embodiments, Figure 4 As shown, the control module 30 is located in a central region of the hub 102 .

[0075] By arranging the control module 30 and the measuring point in the center area of ​​the wheel hub, the distance between the control module 30 and the measuring point can be reduced, and further, the length of the wire electrically connected between the control module 30 and the measuring point can be reduced. Thus, the problem of the wire resistance causing the accuracy of the resistance value in the resistance unit 20 measured by the control module 30 to be reduced due to the wire being too long can be avoided.

[0076] In some embodiments, Figure 4 As shown, the N resistor units 20 are electrically connected to the control module 30 via wires, and the wires are arranged on the spokes of the hub 102 .

[0077] The spokes of the hub 102 are generally arranged along the radial direction of the hub 102 , which is equivalent to a bridge between the rim and the central area. Therefore, the wires are arranged on the spokes, so that the connection between the resistance unit 20 and the measurement point is more convenient.

[0078] The above are related implementations of multiple resistor units. The following describes the implementation of a single resistor unit.

[0079] In some embodiments, Figure 5 As shown, the number of the resistance unit 20 is one, and the control module 30 is used to obtain the resistance value variation parameter of the resistance unit 20 .

[0080] In the case where there is only one resistor unit 20, when the wheel is wading, the resistance value obtained by the control module 30 changes periodically during the rotation of the wheel, and the change period of the resistance value is related to the water depth and the wheel speed. At the same speed, the water depth is proportional to the change period of the resistance value. Therefore, in this embodiment, the wading depth of the wheel can be estimated based on the resistance value change parameter and the wheel speed. Here, the resistance value change parameter can be understood as the change period or change frequency of the resistance value, and the resistance value change parameter can be characterized by a resistance value square wave diagram.

[0081] In some embodiments, the control module 30 is further configured to:

[0082] Obtaining the rotation speed of the wheel 10;

[0083] The wading depth of the vehicle is estimated based on the resistance value change parameters and the rotation speed.

[0084] In this embodiment, when the wheel is wading, the first contact 2042 and the second contact 2043 in the resistance unit 20 are connected by water, and the control module 30 can obtain or detect the resistance value change parameter between the first measuring point 202 and the second measuring point 203. The control module 30 can also obtain the rotation speed of the wheel 10 through the wheel speed sensor, and can calculate the corresponding wading depth through the resistance value change parameter and the rotation speed, and then generate a water depth signal according to the wading depth.

[0085] The embodiment of the present application also provides a vehicle, including the vehicle wading depth measurement system of any of the above embodiments. In addition, the vehicle may also include a vehicle controller, a user terminal and other equipment, and both the vehicle controller and the user terminal can be connected to the wireless receiving device signal in the vehicle wading depth measurement system.

[0086] The vehicle in the embodiment of the present application has the functions of the vehicle wading depth measurement system of any of the above-mentioned embodiments and can achieve its corresponding technical effects. For the sake of concise description, they will not be repeated here.

[0087] Based on the same inventive concept, an embodiment of the present application also provides a method for measuring the wading depth of a vehicle, which can be applied to the vehicle of the above embodiment.

[0088] like Figure 6 The figure is a flow chart of a method for measuring the wading depth of a vehicle provided in an embodiment of the present application.

[0089] like Figure 6 As shown, the method may include:

[0090] S610, estimating the wading depth of the vehicle according to the acquired resistance parameters and wheel parameters;

[0091] S620: Transmit a water depth signal corresponding to the wading depth to at least one of the vehicle controller and the user terminal.

[0092] In S620, the water depth signal can be transmitted only to the vehicle controller. After receiving the water depth signal, the vehicle controller can transmit the water depth signal to the vehicle terminal (or other user terminal). The vehicle terminal may include a display screen. The water depth signal can be transmitted to the vehicle controller and the vehicle terminal (or other user terminal) at the same time.

[0093] Thus, the wading depth of the vehicle is estimated based on the acquired resistance parameters and wheel parameters, and the estimated water depth signal is sent to the vehicle controller or the user terminal. In this way, on the one hand, the vehicle controller can execute the corresponding vehicle control strategy according to the water depth signal to ensure the safety of the vehicle when wading; on the other hand, the user can timely know the wading depth of the vehicle through the user terminal, which can avoid damage to the vehicle or even casualties caused by excessive wading depth.

[0094] In some embodiments, N is greater than 1, the resistance parameter includes the resistance values ​​of the N resistance units, and the wheel parameter includes the arrangement parameters of the N resistance units on the wheel;

[0095] S610 includes:

[0096] estimating the submerged quantity of the resistance unit according to the acquired resistance value;

[0097] The wading depth of the vehicle is estimated according to the arrangement parameters of the N resistance units on the wheels and the submerged quantity.

[0098] The arrangement parameters may include an arrangement mode and an arrangement quantity, wherein the arrangement mode may include arranging the resistor units at equal intervals. The arrangement quantity may include a quantity set by a user, which is not specifically limited here.

[0099] The number of arrangements is positively correlated with the accuracy of the estimated wading depth of the vehicle. The greater the number of arrangements, the higher the accuracy of the estimated wading depth.

[0100] In some embodiments, N is equal to 1, the resistance parameter includes a resistance value variation parameter of the resistance unit, and the wheel parameter includes a rotation speed of the wheel;

[0101] S610 includes:

[0102] The wading depth of the vehicle is estimated according to the acquired resistance value change parameter and the rotation speed.

[0103] In some embodiments, before S620, the vehicle wading depth measurement method may further include:

[0104] In the case where the water depth signal frequently jumps, filtering is performed on the jumping water depth signal to obtain a filtered water depth signal;

[0105] S620 includes:

[0106] The filtered water depth signal is transmitted to at least one of a vehicle controller and a user terminal.

[0107] When a vehicle is wading, the water surface may fluctuate up and down, which may cause the number of submerged resistors to jump frequently, thereby causing the water depth signal to jump frequently. In view of this, in order to obtain a stable water depth signal, the jumping water depth signal can be filtered and the filtered stable water depth signal can be sent to the vehicle controller or the user terminal. As an example, the filtering method can include a median filtering method or an arithmetic average filtering method.

[0108] Therefore, by filtering the frequently changing water depth signal to obtain a stable water depth signal, the vehicle controller or user terminal can display the stable water depth signal after receiving the stable water depth signal, avoiding the problem of reducing user experience caused by displaying an unstable water depth signal.

[0109] In some embodiments, S620 includes:

[0110] When the wading depth is greater than a preset threshold, a water depth signal corresponding to the wading depth is transmitted to the vehicle controller and the user terminal;

[0111] The method further comprises:

[0112] The control strategy corresponding to the water depth signal is executed through the vehicle controller.

[0113] The preset threshold may include a threshold set by a user. Exemplarily, the preset threshold may include a wading depth corresponding to the vehicle chassis height.

[0114] The control strategy may include different strategies corresponding to different wading depths corresponding to the water depth signal. For example, the control strategy may include that when the wading depth corresponding to the water depth signal is the vehicle chassis height, the vehicle controller may control the vehicle to shut down the engine to prevent water from entering the transmitter.

[0115] Therefore, when the wading depth is greater than the preset threshold, the water depth signal corresponding to the wading depth is transmitted to the vehicle controller and the user terminal, and the control strategy corresponding to the water depth signal is executed by the vehicle controller, so that the vehicle can automatically respond to the corresponding wading depth, and can promptly solve the problem of damage to the vehicle caused by excessive wading depth, thereby improving the safety of the vehicle.

[0116] Based on the same inventive concept, an embodiment of the present application also provides a vehicle wading depth measurement device, which can be applied to the vehicle in the above embodiment.

[0119] The transmission module 703 is used to transmit a water depth signal corresponding to the wading depth to at least one of the vehicle controller and the user terminal.

[0120] Therefore, the vehicle's wading depth is estimated based on the acquired resistance parameters and wheel parameters, and the estimated water depth signal is sent to the vehicle controller or user terminal, so that the user can promptly know the vehicle's wading depth through the vehicle controller or user terminal, thereby avoiding damage to the vehicle or even casualties caused by excessive wading depth.

[0126] The calculation module 701 is specifically used for:

[0127] The wading depth of the vehicle is estimated according to the acquired resistance value change parameter and the rotation speed.

[0128] In some embodiments, the vehicle wading depth measurement device 700 may further include:

[0129] A filtering module, before transmitting the water depth signal corresponding to the wading depth to at least one of the vehicle controller and the user terminal, is used to filter the jumping water depth signal in the case where the water depth signal frequently jumps, so as to obtain a filtered water depth signal;

[0130] The transmission module 703 is specifically used for:

[0131] The filtered water depth signal is transmitted to at least one of the vehicle controller and the user terminal.

[0132] Therefore, by filtering the frequently changing water depth signal to obtain a stable water depth signal, the vehicle controller or user terminal can display the stable water depth signal after receiving the stable water depth signal, avoiding the problem of reducing user experience caused by displaying an unstable water depth signal.

[0133] In some embodiments, the transmission module 703 is specifically used to:

[0134] When the wading depth is greater than a preset threshold, a water depth signal corresponding to the wading depth is transmitted to the vehicle controller and the user terminal;

[0135] The vehicle wading depth measuring device 700 may further include:

[0136] The execution module is used to execute the control strategy corresponding to the water depth signal through the vehicle controller.

[0137] Therefore, when the wading depth is greater than the preset threshold, the water depth signal corresponding to the wading depth is transmitted to the vehicle controller and the user terminal, and the control strategy corresponding to the water depth signal is executed by the vehicle controller, so that the vehicle can automatically respond to the corresponding wading depth, and can promptly solve the problem of damage to the vehicle caused by excessive wading depth, thereby improving the safety of the vehicle.
