TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile safety, and more particularly relates to an oil-electric hybrid vehicle water landing protection and personnel escape system and escape method. BACKGROUND

[0002] The water depth of a vehicle can generally be achieved at 300-400 mm, and whether it is water driving, water parking or even falling into deep water, it may cause engine damage, damage to some non-waterproof parts outside the vehicle; when water enters the vehicle passenger compartment, it will cause damage to the vehicle interior and become a waterlogged vehicle, and even the people inside the vehicle may suffocate to death due to inability to escape.

[0003] Since there are many scenarios of vehicle water driving and water landing, the situation is very complex and diverse, the weight of the oil-electric hybrid vehicle is relatively larger, the number of parts is more, and the maintenance cost after damage is also higher, so it is extremely difficult and very important to reduce the number of vehicle parts involved in water driving, reduce the possibility of part damage and protect the safety of people inside the vehicle when driving in water, but there is no special structure scheme and system control method for dealing with shallow water, deep water and water landing of all scenarios and all systems designed for oil-electric hybrid vehicles on the market.

[0024] The application further provides an oil-electric hybrid vehicle falling into water protection and personnel escape method, which utilizes the oil-electric hybrid vehicle falling into water protection and personnel escape system.

[0025] The sensor detects the water immersion depth of the vehicle in real time and transmits the detection data to the vehicle controller in real time.

[0026] When the water immersion depth is between h1 and h2, the vehicle controller sends a signal to the driving unit to reduce the output torque, a signal to the brake unit to start and a signal to the air suspension unit to raise the vehicle body posture.

[0036] This invention provides a water-fall protection and occupant escape system and method for hybrid electric vehicles, the advantages of which are:

[0037] 1. The escape system has 12 floating airbags around the car. This allows the floating airbags to cushion and protect the car when it collides with surrounding objects while floating. At the same time, if one of the airbags ruptures and leaks air, the remaining airbags can still provide enough buoyancy to minimize the damage to the vehicle caused by wading through water.

[0038] 2. The escape system has two airbag lifebuoys on the roof of the car. When the car falls into the water backwards, it can right the car body and help people escape.

[0039] 3. This escape system works in conjunction with the skylight breaking unit and the airbag lifebuoy to shatter and tear open the skylight glass when the car is in deep water, ensuring the safe escape of the occupants.

[0040] 4. The escape system is equipped with a dedicated control unit and solar panels, and the solar panels are placed on the roof inside the vehicle, away from most water sources in wading scenarios, to ensure the reliability of the system operation.

[0041] 5. In this escape system, the engine compartment inflatable airbag is activated when the car falls into the water in the opposite direction and sinks. This causes the engine to fall at the opening of the engine compartment hood, avoiding the beam structure below the engine compartment. The beam structure then becomes the support structure for the engine compartment inflatable airbag, ejecting the engine from the engine compartment opening. This makes the car lighter and easier to float and right, maximizing the safety of the people inside the car.

[0042] 6. The escape system is equipped with underbody inflatable airbags. These airbags can dislodge the battery and fuel tank system, instantly reducing the vehicle's weight and allowing it to float smoothly like a boat if the car falls into the water and cannot float.

[0043] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

DETAILED DESCRIPTION

[0066] Preferred embodiments of the present application will be described in greater detail below. While the preferred embodiments of the present application are described below, it is to be understood that the present application can be otherwise variously embodied and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this present application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0067] The application provides an oil-electric hybrid vehicle falling into water protection and personnel escape system, comprising:

[0068] A plurality of sensors are arranged in the vehicle interior and exterior respectively, all the sensors are connected with the vehicle controller, and the vehicle controller is used for sending control signals to the air suspension unit, the brake unit and the power driving unit;

[0069] A control unit is connected with all the sensors;

[0070] A floating air bag is arranged on the vehicle exterior, and the control unit sends a starting signal to the floating air bag when the vehicle falls into water;

[0071] An air bag life buoy is arranged on the vehicle top, and the control unit sends a starting signal to the air bag life buoy when the vehicle falls into water in reverse;

[0072] A canopy breaking unit is arranged on the vehicle canopy, and the control unit sends a starting signal to the canopy breaking unit when the vehicle personnel is in danger;

[0073] A bottom inflatable air bag is arranged between the vehicle bottom and the battery and the fuel tank, and the control unit sends a starting signal to the bottom inflatable air bag when the sinking speed of the vehicle is greater than the set speed;

[0074] A cabin inflatable air bag is arranged between the front subframe and the engine of the vehicle, and the control unit sends a starting signal to the cabin inflatable air bag when the vehicle falls into water and is in a turnover posture.

[0075] Specifically, the escape system controls the power driving unit, the brake unit and the air suspension unit through the vehicle controller ECU, ensures that the vehicle passes through at a low speed and in a highest posture when driving in shallow water, reduces the possibility of damage of the vehicle external parts caused by wading, reduces the safety hidden trouble caused by too fast driving speed of the vehicle, greatly reduces the maintenance cost caused by vehicle wading, and improves the safety. When the wading depth changes, the floating air bag on the vehicle exterior is started through the special control unit of the system, so that the vehicle floats up, the vehicle parts at high positions are prevented from being soaked by the water outside the vehicle, and the water outside the vehicle is prevented from entering the vehicle interior to soak the interior and passengers in the vehicle interior; in more urgent deep water and falling into water conditions, when the vehicle passengers need to escape, the air bag life buoy at the front of the vehicle roof, the bottom inflatable air bag, the cabin inflatable air bag and the canopy breaking unit are started, so that the vehicle can reduce the weight and float up quickly in the most dangerous situation, and the canopy breaking unit is started according to the situation, so that the vehicle personnel can escape from the vehicle roof. The escape system covers different extreme wading and falling into water conditions, combines the real use scene of the user, and can form multiple escape methods to ensure the safety of the vehicle and the personal and property safety.

[0076] Optionally, the sensor comprises:

[0077] An outside water pressure sensor is arranged at each of the four corners of the vehicle.

[0078] A vehicle height sensor is arranged at each of the four wheels of the vehicle.

[0079] A sonar sensor is arranged at each of the two outside rearview mirrors of the vehicle.

[0080] An inside water pressure sensor is arranged on the floor, steering wheel and roof of the vehicle.

[0081] An oxygen sensor is arranged on the roof of the vehicle.

[0082] Specifically, the outside water pressure sensor is arranged at each of the four corners of the vehicle, the vehicle height sensor is arranged above each of the four wheels, the sonar sensor is arranged at each of the two outside rearview mirrors, the inside water pressure sensor is arranged on the floor, steering wheel and roof of the vehicle, and the oxygen sensor is arranged on the roof of the vehicle.

[0083] Optionally, the control unit is arranged on the roof of the vehicle, the sky screen breaking unit is evenly arranged at four positions in the circumferential direction of the sky screen of the vehicle, the control unit is powered by a solar panel, and the solar panel is arranged on the rear windshield of the vehicle.

[0084] Specifically, the solar panel is arranged on the rear glass, so that the solar panel can generate electricity when the sunlight is sufficient, the generated electricity is stored in a special power supply, and the special power supply and the control unit are arranged inside the roof of the vehicle, so as not to affect the normal operation of the escape system after the vehicle is involved in water.

[0085] Optionally, three floating air bags are arranged at each of the four corners of the vehicle in the circumferential direction, two floating air bags are arranged on the side of the vehicle, and another floating air bag is arranged on the bottom of the vehicle.

[0086] Specifically, a total of 12 air bags are arranged at the four corners of the vehicle, so that the 12 air bags can provide good protection when the vehicle is floating with the water flow and collides with surrounding objects; in addition, the buoyancy provided by the 12 air bags can ensure that the vehicle floats on the water surface, prevents the outside water from entering the vehicle, and prevents the interior parts, articles and personnel in the vehicle from being soaked in the water; the number of the 12 air bags can also ensure that sufficient buoyancy is provided when an individual air bag is accidentally damaged and leaks.

[0087] Optionally, a life buoy is arranged at the front end of the sky screen of the vehicle, and the fragments of the sky screen are connected to the sky screen breaking unit after the sky screen of the vehicle is broken by the sky screen breaking unit.

[0088] Specifically, the airbag life buoy is arranged at the head end of the roof sunroof glass, and after the car is reversed and falls into water, the airbag life buoy can be opened to right the car by buoyancy; when the car does not float on the water bottom, the sunroof breaking unit can break the sunroof glass, the airbag life buoy is connected with the glass corner, the broken glass can be separated from the car by buoyancy, the personnel can more easily escape through the sunroof, and the personnel can wait for rescue on the water surface through the life buoy.

[0089] Arranging the airbag life buoy at the front side of the roof has two advantages: 1. The airbag life buoy is closer to the driver, and is more beneficial to the escape of the driver; 2. Because the engine is in the cabin, the car head is more likely to be downward when falling into water, and the airbag life buoy is more beneficial to tearing the broken sunroof glass.

[0090] Optionally, the oil tank of the car is connected to the bottom of the car through the oil tank binding belt, one end of the oil tank binding belt is matched with the mounting point of the battery of the car, and the explosion guide structure of the oil tank binding belt is correspondingly arranged with the bottom inflation airbag.

[0091] Specifically, the bottom inflation airbag is arranged at the bottom of the car, and the bottom inflation airbag is arranged opposite to the position of the battery oil tank binding belt, so that the bottom inflation airbag is matched with the explosion guide structure of the oil tank binding belt. When the bottom inflation airbag is opened, the oil tank binding belt can be extruded, so that the oil tank binding belt is separated from the oil tank mounting bolt and the opening structure of the oil tank binding belt. The hole of the oil tank binding belt drags the battery mounting bolt, so that the oil tank binding belt is separated from the opening structure of the battery mounting structure. The binding belt drags the oil tank binding belt under the pressure of the collision airbag, so that the battery and the oil tank are separated from the car body.

[0092] In one embodiment, a cabin inflation airbag is arranged in the front cabin of the car, and the cabin inflation airbag is also connected with the cross beam below the front cabin power assembly. When the car falls into water and is in an overturned posture, the cabin inflation airbag is inflated to extrude the power assembly, and the power assembly is damaged and broken under the combined action of the self-gravity of the power assembly and the cabin inflation airbag, so that the engine is reversely separated from the car body, the weight of the car is reduced, and the airbag can provide buoyancy.

[0093] Optionally, the air suspension unit comprises an air spring arranged on the wheel, and the air spring is connected with the vehicle controller through a gas pump.

[0094] Embodiment

[0095] First, the wading depth is described: h is the wading depth; h1 is the safe wading depth, and the recommended value is 300 mm; h2 is the engine allowable wading depth, and the recommended value is 400 mm; h3 is the possible wading depth of the car into water, and the recommended value is 600 mm; h4 is the lower edge height of the car window, and the recommended value is 1000 mm; h5 is the upper edge height of the car window, and the recommended value is 1400 mm. The above wading depth recommended values can be adjusted according to the actual vehicle model.

[0096] As Figure 1 shown, the present application provides an oil-electric hybrid vehicle water protection and personnel escape system, when driving in shallow water, the left and right outside sonar sensors detect the water depth in real time, and the detection data is transmitted to the vehicle controller in real time, when the water depth of any side of the vehicle reaches h1 and does not reach h2, the vehicle controller sends a signal to the drive unit, brake unit and air suspension unit to send the command of reducing output torque, enabling ABS braking deceleration and raising the vehicle posture to the highest posture, so as to pass through the water area at a lower speed and the highest vehicle posture, ensure the safety of driving, reduce the number of water parts outside the vehicle, reduce the failure rate and maintenance cost.

[0097] As Figure 2 shown, the present application provides an oil-electric hybrid vehicle water protection and personnel escape system, when driving in shallow water, the left and right outside sonar sensors detect the water depth in real time, and the detection data is transmitted to the vehicle controller in real time, when the water depth of any side of the vehicle reaches h1 and does not reach h2, the vehicle controller sends a signal to the drive unit, brake unit and air suspension unit to send the command of reducing output torque, enabling ABS braking deceleration and raising the vehicle posture to the highest posture, so as to pass through the water area at a lower speed and the highest vehicle posture, ensure the safety of driving, reduce the number of water parts outside the vehicle, reduce the failure rate and maintenance cost. Figure 3

[0098] As Figure 3 ​As shown, this invention provides a water-fall protection and occupant escape system for hybrid electric vehicles. When the vehicle is in deep water, constituting a flood situation, and the vehicle is adjusted to its highest level position, if the left and right sonar sensors detect a water depth h exceeding h3, the emergency control unit is activated. The instrument panel displays the water situation and a warning about potential property damage caused by water immersion, and asks whether to activate the airbag flotation mode, along with flotation precautions. The driver can select "yes" or "no" on the instrument panel. If "yes" is selected, a signal is transmitted to the control unit, which sends a command to inflate the flotation airbags. If the driver selects "no," the vehicle controller receives the command and sends a signal to the window system to open the windows for the occupant, indicating that escape is possible through the windows in an emergency. However, the occupant can still control the windows to open and close. Once the water level continues to rise and the high-voltage power is cut off, the windows can no longer be controlled.

[0099] like Figure 4 As shown, this invention provides a water-fall protection and occupant escape system for hybrid electric vehicles. When the wading depth h > h4, the four external water pressure sensors at the four corners of the vehicle detect different water pressures, indicating that the vehicle's attitude is not level. At this point, the vehicle may be experiencing significant buoyancy, causing slight drifting. The system requires rapid inflation of the floating airbags. Once fully inflated, the floating airbags protect the vehicle from damage in the event of a collision with surrounding objects. The control unit sends a command to inflate the floating airbags, and the instrument panel displays a warning message. If the vehicle remains in its highest level position and the surrounding floating airbags are not deployed, the instrument panel displays the wading situation and prompts the driver to activate the floating airbags. If the driver selects "yes," the system is activated. If the driver selects "no," the windows are opened, and the instrument panel displays relevant escape information. The driver cannot close the windows at this time; they can only be closed by activating the surrounding floating airbags. If the high-voltage power is cut off, the floating airbags are inflated.

[0100] like Figure 5 As shown, this invention provides a water-fall protection and occupant escape system for hybrid electric vehicles. When the wading depth of the vehicle exceeds h>h5, water pressure sensors at the floor and steering wheel simultaneously detect a certain water pressure, indicating that the wading depth has reached the steering wheel position and the occupants are in danger. The control unit sends a command to the sunroof shattering unit, which is powered by a dedicated power supply and activates to shatter the sunroof. Alternatively, if the oxygen concentration sensor on the roof detects that the oxygen concentration inside the vehicle is too low (below 18%, which, according to the oxygen concentration standard for hypoxic environments, will cause difficulty breathing, dizziness, and decreased cognitive ability), affecting life safety, the control unit sends a command to the sunroof shattering unit, which is powered by a dedicated power supply and activates to shatter the sunroof. The occupants can then escape through the sunroof.

[0101] The oil-electric hybrid vehicle falling into water protection and personnel escape system provided by the application is used when the vehicle is parked on a water road and the driver is not in the vehicle, and the water level gradually rises, such as in the environment where the water level of the vehicle parking lot rises in heavy rain. The vehicle also uses a control unit to receive the instructions of the sensor, then transmits the water information, and controls the floating air bag, air bag life buoy, air curtain breaking unit, vehicle bottom inflatable air bag and cabin inflatable air bag. These are the same as the escape method of the driver in the vehicle. Only three escape methods are different: 1. In the high-voltage power-off state, the control unit detects that the water depth exceeds h1, and automatically controls the vehicle to connect the high-voltage power supply; 2. Since there is no one in the vehicle, the sunroof lifting is not driven, and the air curtain breaking unit is not started; 3. The information sent to the instrument is changed to be sent to the vehicle owner's mobile phone system.

[0102] As Figure 6 and Figure 7As shown, the present application provides an oil-electric hybrid vehicle water protection and personnel escape system. When the vehicle falls into deep water, for example, the vehicle falls into a river from a bridge, the vehicle quickly fills with water after falling into water, and the vehicle window is in an open state. The water pressure sensor inside and outside the vehicle, the left and right sonar sensors will transmit the detection data to the control unit. The control unit analyzes the data to determine whether the vehicle body is quickly filling with water and sinking too fast. If the result is yes, the floating air bag is opened, the engine compartment inflation air bag squeezes the power assembly system, the bottom inflation air bag squeezes the battery box and oil tank system, the vehicle weight is reduced and the vehicle floats up; at the same time, the sky screen is broken by the sky screen breaking unit, the front air bag life buoy on the roof is inflated and started after 0.5s, the vehicle occupants can leave the vehicle from the roof and escape using the life buoy air bag. If the result is no, that is, there is no rapid water filling in the vehicle, the control unit determines whether the vehicle is falling vertically, if the vehicle is falling vertically, the vertical water falling program is executed, the floating air bag is opened, and after the floating air bag is inflated, the control unit detects whether the vehicle floats up; if the vehicle starts to float up, the control logic of the vehicle owner stopping in the water road condition in the vehicle is executed; if the vehicle does not float up, the engine compartment inflation air bag squeezes the power assembly system, the bottom inflation air bag squeezes the battery box and oil tank system, and the vehicle weight is reduced. If the vehicle starts to float up, the control logic of the vehicle owner stopping in the water road condition in the vehicle is executed; if the vehicle still does not float up, the sky screen is broken by the sky screen breaking unit, the front air bag life buoy on the roof is inflated and started after 0.5s, and the vehicle occupants can leave the vehicle from the roof and escape using the air bag life buoy. When the control unit determines that the vehicle is not falling vertically, the air bag life buoy on the roof is started first, and the floating force moment is generated by relying on the floating force of the air bag life buoy on the roof to right the vehicle. The vehicle attitude is monitored in real time by the sensor. If the vehicle is righted within 5s, the vertical water falling control program of the vehicle is executed, and the air bag floating system is opened. If the vehicle is not righted within 5s, the engine compartment air bag squeezes the power assembly system to reduce the weight of the vehicle head, and the vehicle attitude is continuously monitored. If the vehicle is righted within 5s, the vertical water falling control program of the vehicle is executed, and the floating air bag is inflated. If the vehicle is still not righted within 5s, the bottom inflation air bag squeezes the battery box and oil tank system to continuously reduce the weight of the vehicle, and the floating air bag is inflated after 1s. The sunroof breaking unit and the front air bag life buoy on the roof are inflated after 1.5s, the vehicle occupants leave the vehicle from the roof and escape using the air bag life buoy.

[0103] As Figure 8 and Figure 19 As shown, the present application provides an oil-electric hybrid vehicle water protection and personnel escape system, wherein the vehicle outside water pressure sensor 001 is arranged at the four corners of the vehicle, the vehicle height sensor 005 is arranged above the four vehicle wheels and beside the suspension air spring, the sonar sensor 004 is arranged at the two vehicle outside rearview mirrors, the vehicle inside water pressure sensor 002 is arranged at the rear bottom, steering wheel and top of the vehicle, and the oxygen sensor 003 is arranged at the top of the vehicle.

[0104] The escape system also includes a solar panel 006 installed on the rear glass to generate electricity in the presence of sunlight, and supply the dedicated battery 007, and when the dedicated battery 007 is fully charged, it supplies power to the power battery 008; the control unit integrates a dedicated power supply, referred to as a dedicated control unit and power supply assembly, arranged inside the roof. The four sunroof glass breakers 009 in the car are distributed at the four corners of the sunroof glass 014, and the engine 010 is arranged in the front engine compartment position. The power battery 008 and the fuel tank 011 are fixed to the bottom of the vehicle body by the fuel tank strap 012.

[0105] Twelve floating airbags 015 are installed at the four corners of the car, which can provide good protection when the car floats with the water flow and collides with surrounding objects. The twelve floating airbags 015 provide enough buoyancy to keep the car floating on the water surface, preventing water from entering the car and preventing interior parts, items and personnel from being immersed in water. The number of 12 floating airbags 015 can also ensure that enough buoyancy is provided when an individual floating airbag 015 is accidentally damaged and leaks.

[0106] The airbag life buoy 016 is arranged at the front end of the roof sunroof glass 014. Opening the airbag life buoy 016 after the car falls into the water in the opposite direction can right the car by buoyancy. When the car does not float on the water bottom, the airbag life buoy 016 is connected to the glass corner after the sunroof glass 014 is broken by the sunroof breaking unit. The broken glass can be peeled off the car by the buoyancy, making it easier for personnel to escape through the sunroof and wait for rescue on the water surface through the airbag life buoy 016.

[0107] The car bottom inflatable airbag 018 is arranged on the car body floor at the battery fuel tank strap position, corresponding to the blast guide structure 019 of the fuel tank strap 012. When the airbag is opened, it will squeeze the fuel tank strap, causing the fuel tank strap to break at the opening structure 020. At the same time, the hole 021 of the fuel tank strap pulls the battery mounting bolt to make it separate at the battery mounting hole. In this way, the battery also falls off in the case of a broken connection structure. The strap pulls the battery through the broken part under the pressure of the collision airbag, so that the battery is separated from the vehicle body, so that the fuel tank and the battery are smoothly separated from the vehicle body under the pressure of the airbag.

[0108] The engine compartment inflatable airbag 017 is arranged on the crossbeam below the front engine compartment power assembly. When the vehicle falls into the water and is in an inverted position, the airbag inflates and squeezes the power assembly, which is suspended under the combined action of the power assembly's own gravity and the airbag inflation pressure. The engine reversely separates from the vehicle body, reducing the weight of the vehicle, and the airbag can provide buoyancy.

[0109] Having described various embodiments of the application, it is to be understood that the above description is meant to be illustrative only, and that many modifications and variations of the embodiments are possible without departing from the scope and spirit of the described embodiments. Many modifications and variations of the described embodiments are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the described embodiments can be practiced otherwise than as specifically described.
