Description

Technical Field

[0001] This application belongs to the technical field of intelligent vehicles, and particularly relates to a vehicle control method, device, vehicle, electronic device, and storage medium. Background Art

[0002] With the increasing number of vehicle ownership, vehicle safety has become an important concern during the development of vehicles. Vehicle submersion in water is one of the main factors threatening vehicle safety and seriously endangers the personal safety of users.

[0003] In related technologies, usually after the vehicle is submerged in water, the vehicle door is roughly opened by directly blowing up the window, etc., for users to perform self-rescue through the window or sunroof as an escape route. However, if the vehicle's wading depth is relatively shallow, using this method will lead to overreacting self-rescue measures being implemented in unnecessary situations, resulting in additional losses to the vehicle. Or self-rescue measures such as blowing up the window are only taken after the vehicle is completely immersed in water, making it impossible for users to timely detect the danger of vehicle wading. Obviously, the above single wading self-rescue measures for vehicles are not applicable to all scenarios. This leads to additional property losses caused by overreacting or reacting untimely in the scenario of vehicle wading. Summary of the Invention

[0078] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0079] Figure 1 Schematically shows a flow diagram of a vehicle control method provided by the present application, the method including:

[0080] Step 101, obtaining water immersion data collected by a water immersion sensor on the vehicle.

[0081] It should be noted that a water immersion sensor is a sensor that detects whether water leakage occurs in the measured range. Once water leakage occurs, an alarm is immediately issued to prevent relevant losses and hazards caused by the water leakage accident. Therefore, by installing water immersion sensors at various parts of the vehicle, it is possible to determine whether each part of the vehicle has waded through water based on the water immersion data collected by the water immersion sensors.

[0082] In the embodiment of the present application, after the vehicle is started, the vehicle controller will continuously obtain water immersion data from the water immersion sensors on the vehicle, and timely detect that the vehicle has waded through water based on the water immersion data, so as to initiate self-rescue measures for the wading vehicle.

[0083] Step 102, when it is determined that the vehicle has waded through water based on the water immersion data, determine the wading position of the vehicle based on the water immersion data.

[0084] In the embodiment of the present application, after the vehicle has waded through water, the water immersion sensor will send water immersion data reflecting that the vehicle has waded through water to the vehicle controller. The vehicle controller can determine the wading position where water has flooded into the vehicle based on the installation position of the water immersion sensor that receives the water immersion data on the vehicle. Among them, the wading position can be the rear position of the vehicle, the front position of the vehicle, the door position, the sunroof position, etc. Specifically, it can be determined according to the actual layout of the water immersion sensor settings and is not limited here.

[0085] Step 103, obtain a wading self-rescue control strategy that matches the wading position.

[0086] In the embodiment of the present application, considering that when the wading positions on the vehicle are different, the degree of danger of the accident is also different, and the wading self-rescue control strategies that the vehicle controller needs to adopt will also be different. For example: when the vehicle drives directly into the water, that is, the vehicle chassis and the side parts of the vehicle body wade through water, and the vehicle body is not completely immersed in the water and the windows have not been submerged by water, the windows and sunroof can be automatically opened for the user to escape at this time; when the vehicle completely falls into the water, that is, all positions of the vehicle have waded through water, due to the acting force of the water pressure outside the vehicle, even if the door lock is opened, it is difficult for the user to push the door open by himself. At this time, the sunroof can be opened to enable the user to escape from the sunroof; when the vehicle only drives into the water, that is, only the vehicle chassis wades through water, an alarm can be played to inform the user of the wading situation of the vehicle, and then prompt the user to escape from the wading area in time, or prompt the user to open the vehicle or the sunroof to escape. Of course, the above is only an exemplary description, and the specific wading self-rescue control strategies corresponding to different wading positions can be set according to actual needs and are not limited here.

[0087] Step 104, control the vehicle to execute self-rescue measures based on the wading self-rescue control strategy.

[0088] In an embodiment of the present application, after the vehicle controller confirms the wading self-rescue control strategy, it will send the control instructions included in the wading self-rescue control strategy to various components of the vehicle, such as the window controller, door lock controller, airbag controller, etc., so that the vehicle can perform self-rescue measures on the users in the wading vehicle by automatically executing the control instructions. During this process, the vehicle can call for help to the surrounding environment by turning on the horn, or automatically call the rescue phone, so that the users can get timely rescue after escaping.

[0089] In an embodiment of the present application, based on the water immersion data collected by the water immersion sensor installed on the vehicle, the dangerous situation of the vehicle wading can be timely detected, and the wading position of the vehicle can be determined according to the water immersion data, so as to control the vehicle to adopt a wading self-rescue control strategy applicable to the current wading position to automatically implement self-rescue measures for the users, avoiding additional losses caused by the vehicle's overreaction and untimely reaction.

[0090] Optionally, referring to Figure 2 , step 104 includes:

[0091] Step 1041, when the wading position of the vehicle reaches the first body position, control the vehicle to play a wading prompt alarm.

[0092] Step 1042, when the wading position of the vehicle reaches the second body position, control the vehicle to unlock the door and turn on the airbag, where the distance between the first body position and the horizontal plane is less than the second body position. <s

[0093] In an embodiment of the present application, the first body position and the second body position respectively refer to two body positions with different distances from the horizontal plane when the vehicle is wading. Usually, after the vehicle wades, it is the outside of the body that first contacts the water surface. For example, parts such as the front of the vehicle, the door, the rear of the vehicle, the sunroof, and the chassis can all be used as the first body position. At this time, the inside of the vehicle is usually not flooded, and the user can perform self-rescue by self-operation. Therefore, by controlling the vehicle to play a wading prompt alarm, the user can be timely informed of the danger encountered. At this time, the user can escape by self-unlocking the door, window, sunroof, etc.

[0094] Further, after the interior of the vehicle is flooded, for example, when parts such as the engine, vehicle pedals, and door handles are flooded, etc., these positions inside the vehicle can be used as the second body position. If these positions inside the vehicle are flooded, it indicates that most areas of the vehicle have been flooded at this time. Due to the effect of water pressure on the doors, it has become difficult for users to open the doors, windows, sunroofs, etc. by themselves for self-rescue. At this time, the vehicle controller will take over the vehicle control right. In order to enable the doors to be opened smoothly for the user to escape and self-rescue, the vehicle controller will first unlock the door locks of the doors. At this time, due to the external water pressure, the doors still cannot be opened smoothly. Therefore, the vehicle controller will connect the airbag circuit on the vehicle seat side. After receiving the control signal, the vehicle airbag will detonate the ignition medium in the electric detonator, and the gunpowder will ignite the ignition powder and gas generator to generate a large amount of gas, causing the airbag to open instantly. Thus, the unlocked door will be pushed open by the huge tension when the airbag opens, so as to achieve the purpose of opening the door for the user to escape.

[0095] In the embodiment of the present application, when the vehicle wading position is relatively shallow, a wading prompt alarm is played to immediately inform the user of the danger of vehicle wading. When the vehicle wading position is relatively deep, after unlocking the door locks, the airbag is opened to push the door open for the user to escape and self-rescue. Thus, the vehicle wading scenarios are subdivided, and corresponding self-rescue operations are selected based on different degrees of danger, avoiding additional property losses caused by the vehicle's overreaction or untimely reaction, and ensuring the safety of the user by the method of forcibly opening the door by opening the airbag.

[0096] Optionally, referring to Figure 3 , step 1041 includes:

[0097] Step 201, when the wading position reaches the front of the vehicle, control the vehicle to play a wading prompt alarm.

[0098] Step 202, when the wading position reaches the driver's pedal position and no user operation is received, control the vehicle to open the window.

[0099] Step 1042 includes:

[0100] Step 203, when the wading position reaches the driver's door handle position, control the vehicle to unlock the door locks and open the airbag.

[0101] In the embodiment of the present application, since the vehicle counterweight is usually heavier at the front part of the vehicle, when the vehicle falls into water, in most cases, the front of the vehicle is downward. At this time, water will enter the engine compartment. The vehicle controller can first determine whether the immersion of water in the engine compartment affects the engine startup. If water flows into the exhaust or intake pipe, or even into the engine, the engine can no longer start normally. Then the vehicle controller first plays a wading prompt alarm through the speaker in the vehicle to inform the user that the vehicle has waded through water and cannot start. After hearing the wading prompt alarm, since the wading depth of the vehicle is not high and the water pressure is not enough to affect the opening of the car door and window, the user can take operations such as opening the car door, window, and sunroof to open the escape route and escape from the wading vehicle through the escape route to complete self-rescue.

[0102] After playing the wading prompt alarm, if the user does not perform user operations such as opening the window, door, sunroof, etc. after time intervals such as 10s, 15s, etc., and water has entered the vehicle interior and flooded the main driver's pedal, and the water has not flooded the main driver's door handle, the vehicle controller can continue to control the vehicle to play the wading prompt alarm, and then send control commands to the window controller and sunroof controller to control the automatic opening of the window or sunroof for the user to use as an escape route.

[0103] In the embodiment of the present application, if the water has flooded the position of the main driver's door handle, it indicates that the wading depth of the vehicle is relatively deep, and the user's situation is very dangerous. The water pressure outside the vehicle is too high for the user to push open the car door by himself. At this time, the vehicle controller can automatically unlock the car door and open the locking block on the door, and start the airbag to use the instantaneous impact force generated by the opening of the airbag to assist in popping open the car door, opening an escape route for the user, so that the user can quickly escape from the wading vehicle through the opened car door. While the above actions are being carried out, the vehicle controller can also control the electric sunroof to open to reserve other escape routes for the user, achieving the purpose of double guaranteeing the safety of the user.

[0104] In the embodiment of the present application, when the front of the vehicle wades through water, when the front of the vehicle just wades through water, the wading prompt alarm is first turned on, and then as the wading depth of the vehicle increases, the window is gradually automatically opened for the user to escape. Finally, by opening the door lock, the impact force generated by the activation of the airbag is used to break open the car door for the user to escape. Thus, by using a gradually upgraded vehicle wading self-rescue strategy, it avoids additional property losses caused by the vehicle's overreaction or untimely reaction, and guarantees the safety of the user by forcibly opening the car door by activating the airbag.

[0105] Optionally, referring to Figure 4 , step 1041 includes:

[0106] Step 301 : When the wading position reaches the rear end of the vehicle, control the vehicle to play a wading warning alarm.

[0107] Step 302: When no user operation is received, control the vehicle to open the windows.

[0108] The step 1042 includes:

[0109] Step 303 , when the wading position reaches the main driver's door handle position, control the vehicle to unlock the door locks and activate the airbags.

[0110] In an embodiment of the present application, if the rear of a vehicle falls into water first due to reasons such as loading at the rear of the vehicle or the vehicle falling into water, the vehicle controller first controls the vehicle's speakers to play a water warning alarm, thereby informing the user that the vehicle has waded through water and cannot be started. After hearing the water warning alarm, the user can take actions such as opening the doors, windows, and sunroof to open an escape route, and escape from the flooded vehicle through the escape route to complete self-rescue, as the vehicle is not wading through deep water and the water pressure is insufficient to affect the opening of the doors and windows.

[0111] After playing the water wading warning alarm, if the user does not perform any user operation such as opening the window, door, or sunroof after a time interval of, for example, 10s or 15s, the vehicle controller can continue to control the vehicle to play the water wading warning alarm, and then send control instructions to the window controller and sunroof controller to control the window or sunroof to open automatically for the user to use as an escape route.

[0112] Furthermore, if water has already penetrated the vehicle interior and overflowed the main driver's door handle, and the excessive water pressure outside the vehicle makes it difficult for the user to open the door, the vehicle controller can automatically unlock the door and release the door lock block, and then activate the airbag. The instantaneous impact force generated by the airbag deployment assists in opening the door, creating an escape route for the user, allowing the user to escape the flooded vehicle as quickly as possible through the open door. While the above actions are taking place, the vehicle controller can also control the opening of the electric sunroof to reserve an alternative escape route for the user, achieving the purpose of dual protection for user safety.

[0113] The embodiment of the present application first activates a water wading warning alarm when the front of the vehicle just wades through water when the rear end of the vehicle is in water. If the user does not take any action, the car window is automatically opened to allow the user to escape. Finally, the door lock is opened and the impact force generated by the activation of the airbag is used to knock open the car door to allow the user to escape. In this way, the vehicle water wading self-rescue strategy is gradually upgraded to avoid additional property losses caused by excessive or untimely reaction of the vehicle, and the safety of the user is ensured by forcibly opening the car door by activating the airbag.

[0114] Optionally, referring to Figure 5 , step 1041 includes:

[0115] Step 401, when the wading position reaches the sunroof position, control the vehicle to play a wading prompt alarm.

[0116] Step 1042 includes:

[0117] Step 402, when no user operation is received, control the vehicle to unlock the door locks and activate the airbag.

[0118] In the embodiment of the present application, when the vehicle is inverted into the water due to rolling, that is, the top of the vehicle falls into the water first, at this time, the user may also roll due to the rolling of the vehicle and it is difficult to control the vehicle normally. At this time, the vehicle controller first controls the vehicle speaker to play a wading prompt alarm through the vehicle speaker. If the user does not perform any operation after a time interval such as 10s or 15s, the situation is very critical at this time. Since the external water pressure prevents the user from pushing the door open by himself, the vehicle controller can unlock the door automatically and open the locking block on the door, and by activating the airbag, use the instantaneous impact force generated by the activation of the airbag to assist in bouncing open the door, opening an escape route for the user, so that the user can escape from the wading vehicle through the opened door as soon as possible. While the above actions are being performed, the vehicle controller can also control the electric sunroof to open to reserve other escape routes for the user, achieving the purpose of double guaranteeing the safety of the user.

[0119] In the embodiment of the present application, when the top of the vehicle falls, a wading prompt alarm is played to inform the user to save himself in time. If no control operation of the user is received, the door lock is opened, and the impact force generated by the activation of the airbag is used to break open the door for the user to escape. Thus, by using a gradually upgraded vehicle wading self-rescue strategy, it avoids additional property losses caused by the vehicle overreacting or reacting untimely, and guarantees the safety of the user by the method of forcibly opening the door by activating the airbag.

[0120] Optionally, referring to Figure 6 , step 1041 includes:

[0121] Step 501, when the wading position reaches the door position, control the vehicle to play a wading prompt alarm.

[0122] Step 502, when no user operation is received, control the vehicle to open the window.

[0123] Step 1042 includes:

[0124] Step 503, when the wading position reaches any one of the engine compartment position, the driver's pedal position, the rear of the vehicle position, and the sunroof position, control the vehicle to unlock the doors and activate the airbag.

[0125] In the embodiment of the present application, if the side of the vehicle first falls into the water, that is, the door position first touches the water surface, the vehicle controller first determines whether the vehicle is waterlogged. If it is waterlogged, the vehicle controller can play a wading warning alarm through the vehicle's speaker to inform the user of the immersion danger of the vehicle. If the user does not perform any operation after a time interval such as 10 s, 15 s, etc., the vehicle controller will automatically send a control command to the window controller to control the window to automatically lower while playing the wading warning alarm for the user to escape through the window.

[0126] Furthermore, as the wading depth of the vehicle increases, if the waterlogging of the vehicle submerges any one of the engine compartment position, the driver's pedal position, the rear of the vehicle position, and the sunroof position, it means that the wading depth of the vehicle is relatively deep and the water has entered the vehicle interior. At this time, the vehicle controller can use the impact force generated by the activation of the airbag to break open the door for the user to escape, thereby avoiding additional property losses caused by the vehicle's overreaction or untimely reaction by using a gradually upgraded vehicle wading self-rescue strategy, and ensuring the safety of the user by forcibly opening the door by activating the airbag.

[0127] In the embodiment of the present application, when the side of the vehicle falls, a wading warning alarm is played to inform the user to perform self-rescue in a timely manner. If no control operation from the user is received, the window is automatically opened for the user to escape. Finally, the door lock is opened, and the impact force generated by the activation of the airbag is used to break open the door for the user to escape, thereby avoiding additional property losses caused by the vehicle's overreaction or untimely reaction by using a gradually upgraded vehicle wading self-rescue strategy, and ensuring the safety of the user by forcibly opening the door by activating the airbag.

[0128] Figure 7 Schematically shows a vehicle structure diagram provided by the present application. The vehicle includes: a vehicle controller; contact water immersion sensors are respectively arranged at the engine compartment position 11, the driver's pedal position 12, the door handle position 13, the rear of the vehicle position 14, and the sunroof position 15 of the vehicle.

[0129] The vehicle controller is used to control the vehicle to perform self-rescue measures when the vehicle is wading by executing the steps of the vehicle control method described in any of the above embodiments.

[0130] In the embodiments of the present application, there may be 8 contact water immersion sensors, namely, one at the engine position 11, one at the driver's pedal position 12, four at the door handle positions 13 (when there are 4 doors in the vehicle, usually 1 contact water immersion sensor is set at the door handle position of 1 door), one at the rear of the vehicle position 14, and one at the sunroof position 15. The water immersion data of the vehicle is reflected by the contact water immersion sensors at different positions to reflect the wading situation of the vehicle.

[0131] Optionally, referring to Figure 8 , the contact water immersion sensor at the engine compartment position can be set at the engine air intake.

[0132] Optionally, referring to Figure 9 , the installation positions of the engine compartment position 11, the driver's pedal position 12, the door handle position 13, the rear of the vehicle position 14, and the sunroof position 15 of the vehicle are shown in the form of a side view.

[0133] Optionally, referring to Figure 10 , the airbag for assisting in opening the door can be installed under the seat.

[0134] Specifically, when the vehicle controller determines the wading position of the vehicle, it can judge the wading situation of the vehicle according to the signal output sequence of the contact water immersion sensors 11, 14, 15, 13. If the contact water immersion sensor 11 first confirms that it has fallen into the water, it is a scenario where the front of the vehicle has fallen into the water. If the contact water immersion sensor 14 first confirms that it has fallen into the water, it is a scenario where the rear of the vehicle has fallen into the water. If the contact water immersion sensor 15 first confirms that it has fallen into the water, it is a scenario where the roof of the vehicle has fallen into the water. If the contact water immersion sensor 13 first confirms that it has fallen into the water, it is a scenario where the side of the vehicle has fallen into the water. In the scenarios where the vehicle falls into the water at different positions, the control method of the vehicle controller for the vehicle can refer to the above embodiments and will not be elaborated here.

[0135] In the embodiments of the present application, when the wading position of the vehicle is relatively shallow, a wading prompt alarm is played to immediately inform the user of the danger of vehicle wading. When the wading position of the vehicle is relatively deep, the door lock is opened first and then the airbag is activated to push open the door for the user to escape and self-rescue. Thus, the wading scenarios of the vehicle are subdivided, and corresponding self-rescue operations are selected based on different degrees of danger, avoiding additional property losses caused by the vehicle's overreaction or untimely reaction, and ensuring the safety of the user by forcibly opening the door through the activation of the airbag.
