Description

Technical Field

[0001] The invention relates to the field of passenger vehicle electronic and electrical technology, and in particular to a vehicle emergency escape system and a passenger vehicle. Background Art

[0002] With the gradual expansion of passenger transport business and the continuous increase in the number of passengers in passenger vehicles, the market's requirements for the safety of passenger vehicles during operation have also increased. In particular, when an abnormality occurs in a passenger vehicle, the passengers in the passenger vehicle need to be able to safely escape from the passenger vehicle to ensure the safety of the passengers.

[0003] At present, the escape system of passenger vehicles includes emergency window breaking system, emergency door opening system and other related systems. In most cases, the emergency window breaking system and emergency door opening system are independent of each other, using a set of independent control equipment respectively, and rarely linked with other systems of passenger vehicles. At the same time, there are a few solutions of window breaking integrated emergency door opening system, which require the installation of a separate emergency door opening air circuit, additional solenoid valves and controllers for passenger vehicles, which increases the equipment cost and installation and commissioning labor cost of the escape system of passenger vehicles.

[0004] In addition, because the escape systems are independent of each other, the driver needs to operate two sets of equipment to evacuate passengers in an emergency. Furthermore, the emergency door opening system does not have a vehicle speed monitoring function, requiring the driver to wait until the vehicle stops before performing the emergency door opening operation, otherwise the passengers near the door may be thrown out of the vehicle, posing a greater safety risk, thereby reducing the safety and functionality of existing passenger vehicles. Summary of the invention

[0005] In view of this, the present application provides a vehicle emergency escape system and a passenger vehicle, the main purpose of which is to make full use of the existing facilities and equipment of the passenger vehicle, and to solve the technical problems of low functionality and safety of the existing passenger vehicles at a lower cost by modifying the electrical equipment of the passenger vehicle without adding additional air circuit equipment to the passenger vehicle.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0028] In one embodiment, Figure 1 As shown, a vehicle emergency escape system is provided, which is described by taking the application of the system in a passenger vehicle as an example. The vehicle emergency escape system includes an escape controller 100, a combination meter 200, a switch device 300 and at least one door controller 400.

[0029] The escape controller 100 is arranged at the instrument panel in the cab of the passenger vehicle to facilitate the operation of the driver of the passenger vehicle. Here, the escape controller 100 can be connected to a switch device (not shown in the figure). When the driver touches the switch device, the switch device sends an escape command to the escape controller 100. In addition, the escape controller 100 can be connected to a human-machine interactive device such as a serial port touch screen (not shown in the figure). When the driver touches the escape icon on the screen of the human-machine interactive device, the human-machine interactive device sends an escape command to the escape controller 100. Furthermore, the instrument combination 200 is an existing interactive device in the passenger vehicle, which provides the driver with the required information such as vehicle operating parameters, faults, mileage, etc., and has a certain computing capability.

[0030] Specifically, the escape controller 100 is used to respond to the escape command and send an escape signal to the instrument cluster 200 and the switch device 300 respectively; here, the signal output end of the escape controller 100 is connected to the signal input end of the instrument cluster 200 and the control end of the switch device 300 respectively, so as to send the escape signal to the instrument cluster 200 and the switch device 300.

[0031] Further, the combination meter 200 is used to monitor the traveling speed of the passenger vehicle, and when the escape signal is received and the traveling speed is less than or equal to the preset speed value, the switch device 300 sends a door opening signal to the door controller 400. Here, if the passenger vehicle is a public bus, the preset speed value may be 1 kilometer per hour, and if the passenger vehicle is a highway bus, the preset speed value may be 3 kilometers per hour, and the specific value of the preset speed value may be determined according to actual conditions.

[0032] Specifically, the switch device 300 is used to make the combination meter 200 and the door controller 400 in a conducting state when receiving the escape signal; specifically, when the control end of the switch device 300 receives the escape signal, the first end and the second end of the switch device 300 are in a conducting state, and when the control end of the switch device 300 does not receive the escape signal, the first end and the second end of the switch device 300 are in a disconnected state. Further, the signal output end of the combination meter 200 is connected to the first end of the switch device 300, and the second end of the switch device 300 is connected to the control end of each door controller 400, so that the combination meter 200 can send the door opening signal to the door controller 400 via the switch device 300.

[0033] Further, the door controller 400 is used to control at least one door of the passenger vehicle to be in an open state when receiving the door opening signal. Here, each door controller 400 can respectively control one door of the passenger vehicle to be opened or closed. When the door controller 400 receives the door opening signal from the combination meter 200 via the switch device 300, the door controller 400 controls the door corresponding to the door controller 400 to be opened.

[0034] The present embodiment provides a vehicle emergency escape system. When the driver of a passenger vehicle finds that the passenger vehicle is abnormal and needs to evacuate the passengers on the passenger vehicle, an escape command can be issued to the escape controller, so that the escape controller sends an escape signal to the combination meter and the switch device respectively; further, the combination meter monitors the travel speed value of the passenger vehicle in real time, and when the escape signal is received from the escape controller and the travel speed value of the passenger vehicle is less than or equal to the preset speed value, the switch device sends a door opening signal to the door controller through the switch device. At the same time, when the switch device receives the escape signal, the circuit between the combination meter and the door controller is in a conducting state, so that the combination meter can send the door opening signal to the door controller through the switch device, and then the door controller controls at least one door of the passenger vehicle to be in an open state, ensuring that the passengers can escape safely. The technical solution provided by the present application can prevent the passenger vehicle from opening the door at a high speed, and prevent the passenger vehicle from being controlled to open the door in an emergency before the vehicle speed drops to a lower speed value due to the driver's mistake, thereby ensuring the safety of the passengers. At the same time, by setting a switch device to prevent the combination instrument from mistakenly sending a door opening signal when the escape signal is not received, it can effectively avoid the abnormal opening of the doors of passenger vehicles, thereby improving the safety of passenger vehicles during operation. At the same time, this system can be developed and expanded on the basis of the original glass breaking system and body system, reusing existing resources and significantly reducing the cost of using the system.

[0035] In an optional embodiment, if Figure 2 As shown, the switch device is a relay 310; the escape signal includes an escape high level signal and an escape low level signal; wherein the signal output end of the escape controller 100 also includes a high level output end and a low level output end. For passenger vehicles, the signal voltage of the escape high level signal is usually 24 volts, and the signal voltage of the escape low level signal is usually 0 volts.

[0036] Specifically, the high level output end of the escape controller 100 is connected to the first end of the relay coil 311 of the relay 310 , and the low level output end of the escape controller 100 is connected to the second end of the relay coil 311 of the relay 310 .

[0037] Furthermore, the escape controller 100 is used to send an escape high level signal to the first end of the relay coil 311 and send an escape low level signal to the second end of the relay coil 311 in response to an escape instruction.

[0038] Furthermore, the first end of the normally open contact 312 of the relay 310 is connected to the signal output end of the instrument cluster 200, and the second end of the normally open contact 312 is connected to the control end of each door controller 400, so that when the normally open contact 312 is turned on, the door opening signal output by the instrument cluster 200 can be sent to the control of the door controller 400 through the normally open contact 312; when there is a potential difference between the two ends of the relay coil 311, a current is generated in the relay coil 311 to turn on the normally open contact 312. Due to the irreversibility of the debugging of the emergency escape system, the batch debugging problem cannot be caused. The embodiment provided by the present application can control whether the instrument cluster can send the escape door opening signal to the door controller based on the relay, so as to avoid the safety risk of accidental door opening in non-emergency situations caused by the inability to verify the logic of the output end of the instrument cluster.

[0039] In an optional embodiment, if Figure 3 As shown, the door controller 400 includes a diode 410 and a door pump device 420. The door pump device 420 is used to control at least one door of the passenger vehicle to be in an open state or a closed state. When the door pump device 420 receives a door opening signal, the door pump device 420 performs a door opening action to control the passenger vehicle to open the front door and the middle door.

[0040] Specifically, the anode end of the diode 410 is connected to the second end of the normally open contact 312 as the control end of the door controller 400, and the cathode end of the diode 410 is connected to the control end of the door pump device 420; here, when the normally open contact 312 of the combination meter 200 sends a door opening signal to the door controller 400, the door opening signal is sent to the door pump device 420 via the diode 410 to control the passenger vehicle to open the door. The embodiment provided by the present application can eliminate cross-flow through the diode, prevent the door opening signals of multiple door pump devices from cross-flowing in non-emergency situations, and improve the reliability of the system.

[0041] In an optional embodiment, if Figure 4 As shown, the vehicle emergency escape system also includes a vehicle speed sensor 500, the signal output end of the vehicle speed sensor 500 is connected to the vehicle speed collection end of the combination meter 200, and the vehicle speed sensor 500 is used to determine the travel speed value of the passenger vehicle in real time, and send the travel speed value to the combination meter 200, so that the combination meter 200 can monitor the travel speed value of the passenger vehicle and perform subsequent processing. The embodiment provided by the present application can collect the travel speed value of the passenger vehicle in real time based on the vehicle speed sensor, and send the travel speed value to the combination meter as a logic judgment element, thereby improving the reliability and safety of the system.

[0042] In an optional embodiment, if Figure 4 As shown, the light control end of the combination meter 200 is connected to the control end of the exterior lamp 600 of the passenger vehicle, and the combination meter 200 is also used to control the exterior lamp 600 of the passenger vehicle to emit a warning light when receiving the escape signal. Here, the warning light can be a double flash signal light. The embodiment provided by the present application can timely control the passenger vehicle to turn on the double flash alarm when the escape controller is triggered to output the escape signal, thereby improving the safety of the passenger vehicle.

[0043] In an optional embodiment, if Figure 4 As shown, the vehicle emergency escape system further includes a dispatch host 700 ; a control end of the dispatch host 700 is connected to a command output end of the combination instrument 200 .

[0044] Specifically, the combination instrument 200 is also used to send an alarm message to the dispatch host 700 when receiving the escape signal, so as to control the dispatch host 700 to send abnormal alarm information to the remote host computer 800 based on wireless communication. Here, the combination instrument 200 and the dispatch host 700 are connected based on the controller area network bus (Controller Area Network, CAN), so that the combination instrument 200 can send alarm information of the CAN message protocol to the dispatch host 700. Further, the dispatch host 700 establishes a wireless connection with the host computer 800 based on the mobile information system, wherein the mobile information system can be a 4G or 5G mobile information system, and the host computer 800 can be a computer system such as a cloud platform system of the operating company of the passenger vehicle. The embodiment provided in the present application can send an abnormal alarm to the cloud platform when an abnormality occurs in the passenger vehicle and the driver takes measures to evacuate the passengers, thereby improving the functionality of the vehicle emergency escape system.

[0045] In an optional embodiment, the vehicle emergency escape system also includes a plurality of escape striker devices, each of which is respectively arranged at the window glass of the passenger vehicle; here, at least one escape striker device can be arranged at each window glass of the passenger vehicle, and each escape striker device is used to shatter the window glass to facilitate the escape of the occupants.

[0046] Furthermore, the escape controller is also used to respond to the escape command and send an escape signal to each of the escape striker devices respectively to control the escape striker devices to smash the vehicle window glass. Here, the escape controller can send a high voltage signal to the positive power access terminal of the escape striker device and send a low voltage signal to the negative power access terminal of the escape striker device to energize the escape striker device and smash the vehicle window glass. The embodiment provided by the present application can promptly smash the windows of the passenger vehicle when the driver of the passenger vehicle triggers the escape controller to evacuate the passengers, so as to facilitate the escape of the passengers.

[0047] The vehicle emergency escape system provided by the present application can prevent passenger vehicles from opening doors at high speeds, and prevent the driver from controlling the emergency door opening of passenger vehicles before the vehicle speed drops to a lower speed value due to the driver's mistake, thereby ensuring the safety of passengers, and can prevent the combination instrument from mistakenly sending a door opening signal and opening the door without receiving an escape signal, and can effectively prevent the abnormal opening of passenger vehicle doors. At the same time, it can realize functions such as breaking glass, opening doors, and alarming of passenger vehicles with one click, providing faster passenger escape time and emergency response speed, thereby significantly improving the safety of passenger vehicles.

[0048] Furthermore, an embodiment of the present invention provides a passenger vehicle, comprising the vehicle emergency escape system as described above.
