Description

Technical Field

[0001] The present application relates to the field of automobile technology, and more specifically, to a vehicle wading protection method, a vehicle wading protection device, a vehicle wading protection system and a vehicle. Background Art

[0002] With the development of society, cars have become an important means of transportation. The impact of car wading (such as cars falling into water or flooding) on ​​drivers and passengers as well as the car itself cannot be ignored.

[0003] At present, there are some protection measures for automobiles wading. For example, a water level sensor is arranged on the body of the vehicle to detect whether the vehicle is wading through the water level sensor. If the vehicle is wading, the corresponding airbag is activated to make the car float on the water. However, the airbag false triggering rate of this scheme is high. For example, when a car is driving on a flooded road, the water on the road surface fluctuates up and down, causing the water level sensor to detect that the vehicle is wading, resulting in a misjudgment of the vehicle's wading status (i.e. whether it is wading), which in turn causes the airbag to be falsely triggered, causing additional accidents or property losses.

[0032] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] This embodiment involves a variety of vehicle wading scenarios, such as a vehicle accidentally falling into water, a vehicle parked in a flooded area due to heavy rain, a vehicle driving on a flooded road, etc. When a vehicle wades in water, it is very likely to put the driver and passengers in danger or cause property losses.

[0038] At present, there are some protection measures for automobiles wading. For example, a water level sensor is arranged on the body of the vehicle to detect whether the vehicle is wading. If the vehicle is wading, the corresponding airbag is activated to make the car float on the water. This technology can protect the safety of drivers and passengers and avoid losses to a certain extent, but the airbag false triggering rate of this scheme is high. For example, when a car is driving on a flooded road, the water on the road surface fluctuates up and down, causing the water level sensor to detect that the vehicle is wading, resulting in a misjudgment of the vehicle's wading status (i.e. whether it is wading), which in turn causes the airbag to be falsely triggered, causing additional accidents or property losses.

[0039] For another example, a vehicle posture sensor (gyroscope / gravity sensor) is added to the water level sensor to avoid false triggering of the airbag by detecting the vehicle posture. This technology can avoid false triggering of the airbag to a certain extent, but it cannot completely solve the problem. For example, when the vehicle body tilts due to defects in the water-logged road surface, it will still cause false triggering of the airbag. At the same time, this solution also brings another problem. When the vehicle body weight is balanced, there is a risk that the airbag cannot be popped out or cannot be popped out in time.

[0040] For another example, a distance sensor is added to the water level sensor to detect the distance from the chassis to the ground to avoid false triggering. This method still has extreme cases of false triggering. For example, when there is water on the ground, it will affect the detection distance and cause inaccurate detection, or even the detected distance value will become the distance from the chassis to the water surface, causing the decision logic to completely fail and unable to play a protective role. In addition, the distance sensor is set on the chassis of the vehicle body, and the height of the chassis from the ground is relatively low. When the height of the water on the ground is not greater than the height of the chassis, it will cause the airbag to be falsely triggered, causing accidents or property losses.

[0041] In order to solve the above problems, the applicant found that when a vehicle is flooded or falls into water accidentally, the vehicle body will be subject to the upward buoyancy of the water, thereby reducing the pressure on the vehicle suspension. In other words, when the vehicle body is flooded or falls into water, the degree of compression of the vehicle suspension will be less than when the vehicle is driving normally or parked on the ground.

[0042] Based on this, this embodiment provides a vehicle wading protection method that can prevent false triggering. Figure 1 First, a vehicle wading protection system involved in this embodiment is briefly introduced. The system may include a water level sensor 1100, a suspension sensor 1200 and a vehicle wading protection device (not shown in the figure).

[0043] The water level sensor 1100 and the suspension sensor 1200 are respectively connected to the vehicle wading protection device.

[0044] The water level sensor 1100 can be used to detect the wading state information of the vehicle. The wading state information of the vehicle indicates whether the vehicle is wading or not wading.

[0045] The suspension sensor 1200 can be used to detect the compression degree information of the vehicle suspension. The vehicle suspension connects the vehicle body and the wheels, and supports and cushions the vehicle body. When the vehicle is parked on the ground, due to the weight of the vehicle body, the vehicle suspension is in a certain degree of compression. In this embodiment, the information corresponding to the compression degree is referred to as the initial compression degree information. When the vehicle is traveling on a bumpy road, the vehicle suspension moves up and down. During the upward movement of the vehicle suspension, the compression degree of the suspension will decrease relative to the initial compression degree. During the downward movement of the vehicle suspension, the compression degree of the suspension will increase relative to the initial compression degree. When the vehicle falls into water, due to the upward buoyancy of the water on the vehicle body, the compression degree of the vehicle suspension will decrease relative to the initial compression degree.

[0046] The vehicle wading protection device can be used to obtain the vehicle's wading status information detected by the water level sensor 1100 and the vehicle suspension compression degree information detected by the suspension sensor 1200, and trigger the vehicle wading protection strategy based on the vehicle's wading status information and the vehicle suspension compression degree information.

[0047] The suspension sensor 1200 may be a distance sensor for detecting the deformation of the vehicle suspension shock-absorbing spring or the travel of the vehicle suspension. For example, it may be a contact distance sensor for detecting the distance between the top plate and the bottom plate of the vehicle suspension shock-absorbing spring. The suspension sensor 1200 may also be a pressure sensor for detecting the pressure on the vehicle suspension shock-absorbing spring.

[0048] The vehicle wading protection system may further include an execution module. The execution module may include an inflation module (not shown) and an airbag 1300. The inflation module may be used to inflate the airbag 1300. The inflation module is connected to the airbag 1300 through a pipeline. The inflation module is fixed to a position above the bottom guard plate of the vehicle chassis, and the airbag 1300 is fixed below the vehicle chassis.

[0049] Combine the following Figure 2 , introduces the vehicle wading protection method provided by this embodiment. The method may include steps S110 to S130.

[0050] Step S110, obtaining the wading status information of the vehicle.

[0051] The water level threshold of the vehicle can be acquired in advance, and a water level sensor can be deployed at a vehicle body position corresponding to the water level threshold.

[0052] Optionally, a water level sensor may be used to detect whether there is water at the location of the water level sensor. If the water level sensor detects that there is water, the vehicle has waded through water. Otherwise, the vehicle has not waded through water.

[0053] Optionally, the water level information of the location of the vehicle can also be detected. When the water level detected by the water level sensor is greater than the water level threshold of the vehicle, the vehicle is wading. Otherwise, the vehicle is not wading.

[0054] The water level height threshold can be set according to actual conditions, can be set according to the height of important components of the vehicle, can also be set according to the chassis height of the vehicle, and of course can also be set according to other rules. This embodiment does not make specific restrictions on this.

[0055] It can be understood that in this embodiment, there is no limitation on the type of information detected by the water level sensor, and it only needs to be able to reflect the wading state of the vehicle.

[0056] As an example, a water level sensor 1100 may be installed on the left and right sides of the front bottom of the vehicle body and the left and right sides of the rear bottom of the vehicle body. The four water level sensors 1100 are electrically connected to the vehicle wading protection device respectively. The vehicle wading protection device obtains the wading state information of each water level sensor 1100 respectively.

[0057] Step S120, obtaining compression degree information of the vehicle suspension.

[0058] In this embodiment, the compression degree information of the vehicle suspension includes at least any one of the following manifestations: the deformation of the suspension shock absorber spring, the pressure on the suspension shock absorber spring, and the travel of the suspension.

[0059] The vehicle suspension may include a shock absorbing spring. In this case, the compression degree information of the vehicle suspension may be embodied based on the deformation or pressure of the suspension shock absorbing spring. The shock absorbing spring may be, for example, a rigid spring, an air spring, a torsion bar spring, etc.

[0060] The deformation of the shock absorbing spring can be detected by a distance sensor. The type of the distance sensor is not specifically limited. It can be a non-contact distance sensor, such as a sensor that detects distance optically or acoustically. It can also be a contact distance sensor, such as a pull rod displacement sensor. In this embodiment, the use of a contact distance sensor has low requirements on the environment and can improve the measurement precision and accuracy. At the same time, the scope of application for vehicle driving environments is also wider.

[0061] As an example, Figure 3As shown, a distance sensor 310 for detecting the deformation of the shock absorbing spring can be arranged in parallel with the shock absorbing spring 320 of the suspension. One end of the distance sensor is connected to the top plate of the shock absorbing spring, and the other end is connected to the bottom plate of the shock absorbing spring. When the distance value between the top plate and the bottom plate of the shock absorbing spring decreases, it indicates that the compression degree of the suspension increases. Conversely, when the distance value between the top plate and the bottom plate of the shock absorbing spring increases, it indicates that the compression degree of the suspension decreases.

[0062] In this example, the distance between the top plate and the bottom plate of the shock absorbing spring can be detected in real time, and compared with the distance between the top plate and the bottom plate of the shock absorbing spring under the initial compression degree, the deformation of the shock absorbing spring at this time can be obtained. The deformation is used as information to characterize the compression degree of the suspension.

[0063] For example, the distance between the top plate and the bottom plate of the shock absorber spring corresponding to the initial compression degree of the suspension is 300mm. When the vehicle falls into the water, due to the upward buoyancy of the water on the vehicle body, the compression degree of the shock absorber spring decreases, and the distance between the top plate and the bottom plate becomes 350mm. At this time, the deformation of the shock absorber spring is +50mm.

[0064] The pressure on the shock absorbing spring can be detected by the pressure sensor. When the pressure on the shock absorbing spring decreases, it indicates that the compression degree of the suspension decreases. Conversely, when the pressure on the shock absorbing spring increases, it indicates that the compression degree of the suspension increases.

[0065] Similarly, the pressure on the shock absorbing spring can be detected in real time and compared with the pressure on the shock absorbing spring at the initial compression level to obtain the pressure on the shock absorbing spring at this time. The pressure is used as information to characterize the degree of compression of the suspension.

[0066] The vehicle suspension may also be of other types. In this case, the degree of compression of the vehicle suspension may be based on the travel of the suspension. The travel of the suspension may be the distance the suspension moves relative to the initial compressed state.

[0067] Of course, the degree of compression of the vehicle suspension can also be determined based on the initial travel of the suspension when there is no pressure or the initial distance between the top and bottom ends of the suspension damping spring, combined with the initial degree of compression information of the suspension. This will not be discussed in detail here.

[0068] As an example, a suspension sensor 1200 may be installed on each shock absorbing spring of the suspension. The four suspension sensors 1200 are electrically connected to the vehicle wading protection device respectively. The vehicle wading protection device respectively obtains the compression degree information of the suspension detected by each suspension sensor 1200.

[0069] It can be understood that in this embodiment, obtaining the vehicle's wading status information and the vehicle's suspension compression degree information can be performed simultaneously, or the vehicle's wading status information can be obtained first, and then the vehicle's suspension compression degree information is obtained after it is determined that the vehicle is wading.

[0070] Step S130 , triggering a vehicle wading protection strategy according to the wading state information and the compression degree information.

[0071] In this embodiment, multiple vehicle wading protection strategies and trigger conditions corresponding to each vehicle wading protection strategy can be preset. When the vehicle wading state information and the suspension compression degree information meet the corresponding trigger conditions, the corresponding vehicle wading protection strategy is triggered.

[0072] As an example, the vehicle wading degree can be divided into different levels. For example, the vehicle is driving on a flooded road, and the water fluctuates up and down, causing the vehicle to wade. This wading degree can be set to level one. Another example is that the vehicle body is flooded due to continuous heavy rain, resulting in damage to important components. Another example is that the vehicle accidentally falls into the water, and this wading degree can be set to level two.

[0073] In this example, when the wading level is level 1, a corresponding first vehicle wading protection strategy may be formulated, and when the wading level is level 2, a corresponding second vehicle wading protection strategy may be formulated.

[0074] This embodiment does not specifically limit the number or level of vehicle wading protection strategies, which can be pre-determined according to actual needs.

[0075] In this embodiment, the vehicle wading state information detected by all water level sensors and the suspension compression degree information detected by all suspension sensors can be detected in real time, and the execution module is triggered to execute the vehicle wading protection strategy according to all wading state information and all suspension compression degree information. In this embodiment, by introducing the detection of the compression degree of the vehicle suspension, the vehicle wading protection strategy is triggered according to the vehicle wading state information and the vehicle suspension compression degree information, which not only enables the wading protection strategy to be triggered in time when the vehicle wades, but also effectively reduces the false triggering rate of the vehicle airbag.

[0076] Since the vehicle is driving on a flooded road, the water may fluctuate up and down, causing the vehicle water level sensor to detect wading. However, in this scenario, if the airbag is triggered to float the vehicle, additional accidents or losses will occur. Therefore, in this embodiment, if Figure 4 As shown, step 130 may include step S131.

[0077] Step S131, triggering a first vehicle wading protection strategy when the wading state information indicates that the vehicle is wading and the compression degree indicated by the compression degree information of the vehicle suspension is greater than or equal to a first threshold.

[0078] The size of the first threshold value can be determined according to the minimum compression degree information of the suspension allowed after the vehicle wades. When the compression degree information of the vehicle suspension is equal to the minimum compression degree information, the vehicle wading position just reaches the preset minimum vehicle body wading safety position. The minimum vehicle body wading safety position can indicate that when the vehicle wading position is at this position, no damage will be caused to important components of the vehicle. When the compression degree of the vehicle suspension is greater than the minimum compression degree, the vehicle wading position has not yet reached the preset minimum vehicle body wading safety position. When the compression degree of the vehicle suspension is less than the minimum compression degree, the vehicle wading position has exceeded the preset minimum vehicle body wading safety position.

[0079] Of course, the first threshold value may also be predetermined according to other rules, as long as the vehicle's wading position can be identified in a timely and correct manner to protect important components of the vehicle from being damaged.

[0080] The specific value of the first threshold value can be set according to the actual situation. The value of the first threshold value is related to the weight of the vehicle itself, the stiffness of the suspension shock absorber spring, and the performance of other structural parts. As an example, when the weight of the vehicle and the performance of other structural parts are the same, when the stiffness of the suspension shock absorber spring is large, the first threshold value that needs to be set is relatively large. When the stiffness of the suspension shock absorber spring is small, the first threshold value that needs to be set is relatively small.

[0081] When the compression degree of the vehicle suspension is based on the deformation of the suspension shock absorber spring or the travel of the suspension, the first threshold is a distance threshold. When the compression degree of the vehicle suspension is based on the pressure on the suspension shock absorber spring, the first threshold is a pressure threshold.

[0082] The first threshold value can be set based on the initial compression state of the suspension, or can be set based on the state of the suspension without pressure. It can be understood that the setting of the first threshold value and the determination of the deformation of the shock absorber spring, the pressure on the shock absorber spring, or the travel of the suspension that reflects the degree of compression of the suspension adopt the same reference. In other words, if the first threshold value is determined based on the initial compression degree of the suspension, then the compression degree of the suspension during real-time detection should also be determined based on the initial compression degree of the suspension.

[0083] The first vehicle wading protection strategy may be to remind the user that the vehicle is wading and that the user needs to pay attention to driving safety. The reminder method may include multiple methods, such as popping up text on a display screen or issuing a voice reminder.

[0084] In some embodiments, when the degree of compression of the vehicle suspension is reflected based on the deformation of the suspension shock absorber spring, when the wading state information indicates that the vehicle is wading, and the deformation of the vehicle suspension shock absorber spring relative to the initial compression state is less than or equal to the first preset distance threshold, the first vehicle wading protection strategy is triggered. Taking the first preset distance threshold as +50mm as an example, when the deformation of the vehicle suspension shock absorber spring relative to the initial compression state detected in real time is +40mm, the first vehicle wading protection strategy is triggered.

[0085] When the degree of compression of the vehicle suspension is reflected based on the travel of the suspension, the first vehicle wading protection strategy is triggered when the wading state information characterizes that the vehicle is wading and the travel of the vehicle suspension relative to the initial compression state is less than or equal to a first preset distance threshold.

[0086] When the degree of compression of the vehicle suspension is reflected based on the pressure exerted on the suspension shock absorber spring, the first vehicle wading protection strategy is triggered when the wading state information characterizes that the vehicle is wading and the pressure exerted on the shock absorber spring of the vehicle suspension relative to the initial compression state is greater than or equal to a first preset pressure threshold.

[0087] In other embodiments, when the degree of compression of the vehicle suspension is reflected based on the deformation of the suspension shock-absorbing spring, when the wading state information indicates that the vehicle is wading, and the real-time detection distance of the shock-absorbing spring of the vehicle suspension is greater than or equal to the first preset distance threshold relative to the initial distance when there is no pressure, the first vehicle wading protection strategy is triggered. As an example, the distance from the top plate to the bottom plate of the shock-absorbing spring of the vehicle suspension in the no-pressure state is 400mm, the distance from the top plate to the bottom plate of the shock-absorbing spring of the vehicle suspension detected in real time is 350mm, and the first preset distance threshold is 40mm. At this time, the first vehicle wading protection strategy is triggered.

[0088] Preferably, the distance between the top plate and the bottom plate of the suspension shock absorber spring can be detected by using a contact distance sensor. When the wading state information indicates that the vehicle is wading, and the real-time detected distance is less than or equal to the first preset distance threshold relative to the initial distance between the top plate and the bottom plate of the vehicle suspension shock absorber spring in the initial compression state, the first vehicle wading protection strategy is triggered. As an example, the real-time detected distance between the top plate and the bottom plate of the vehicle suspension shock absorber spring is 350 mm, and the first preset distance threshold is 370 mm. At this time, the first vehicle wading protection strategy is triggered.

[0089] It can be understood that the specific triggering condition can be determined according to the setting reference of the first threshold and the type of suspension compression degree information, which is not specifically limited here.

[0090] This embodiment can overcome the defect of the airbag being triggered erroneously when the vehicle is driving normally on a flooded road in the existing solution by referring to the judgment of the compression degree of the suspension.

[0091] In some scenarios, when a vehicle is driving on a flooded road at a high speed, the compression of the vehicle suspension may be less than the first threshold. However, in this scenario, if the airbag is triggered to float the vehicle, additional accidents or losses may occur.

[0092] Therefore, in this embodiment, if Figure 4 As shown, step 130 may further include step S132.

[0093] Step S132, triggering a second vehicle wading protection strategy when the wading state information indicates that the vehicle is wading, the compression degree indicated by the compression degree information of the vehicle suspension is less than a first threshold, and the duration is greater than a second threshold.

[0094] The duration is the time during which the compression degree of the vehicle suspension is less than the first threshold value. It can be understood that the duration represents the time during which the compression degree of the vehicle suspension is less than the first threshold value. During this duration, the compression degree of the vehicle suspension may vary or remain unchanged.

[0095] The second threshold is a time threshold, which can be set according to actual conditions. For example, the second threshold is 3 seconds.

[0096] This embodiment can further reduce the false triggering rate of the airbag by introducing the judgment of the duration that the compression degree of the vehicle suspension is less than the first threshold.

[0097] In this embodiment, Figure 4 As shown, step 130 may further include step S134.

[0098] Step S134: when the duration is greater than the second threshold, triggering the second vehicle wading protection strategy.

[0099] The second vehicle wading protection strategy may include any one or any combination of the following: inflating the airbag; opening the window; opening the door. Of course, the second vehicle wading protection strategy may also be other forms of protection strategies, which are not specifically limited here.

[0100] This embodiment tightens the triggering conditions of the second vehicle wading protection strategy to prevent the airbag from being triggered inadvertently.

[0101] Preferably, when the compression degree of all suspensions is less than the first threshold, the timing is restarted. When the duration of the state that the compression degree of all suspensions is less than the first threshold is greater than the second threshold, the second vehicle wading protection strategy is triggered.

[0102] Of course, according to actual needs, when the compression degree of part of the suspension is less than the first threshold, the timing starts. When the duration of the state where the compression degree of the part of the suspension is less than the first threshold is greater than the second threshold, the second vehicle wading protection strategy is triggered. No specific limitation is given here.

[0103] It can be understood that in this embodiment, when the vehicle wading state information indicates that the vehicle is not wading, the wading protection strategy may not be triggered.

[0104] This embodiment also provides a vehicle wading protection device, which may include a first acquisition module, a second acquisition module and a control module.

[0105] The first acquisition module can be used to acquire the wading status information of the vehicle.

[0106] The second acquisition module can be used to obtain compression degree information of the vehicle suspension.

[0107] The control module can be used to trigger the vehicle wading protection strategy according to the wading state information and the compression degree information.

[0108] This embodiment also provides a vehicle wading protection device. Figure 5 As shown, the device 2000 may include a memory 2100 and a processor 2200, wherein the memory 2100 is used to store computer instructions, and the processor 2200 is used to call the computer instructions from the memory 2100 to execute the vehicle wading protection method as described above in this application.
