Detailed Implementation

[0040] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0041] The components of the embodiments of this application described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0042] In the following text, the terms "comprising," "having," and their cognates, which may be used in various embodiments of this application, are intended only to indicate a particular feature, number, step, operation, element, component, or combination thereof, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations thereof, or adding the possibility of one or more combinations thereof. Furthermore, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0043] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this application pertain. Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0044] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] In existing technologies, the eCall system cannot guarantee the safety of new energy vehicles. For example, the risk of spontaneous combustion in new energy vehicles cannot be detected in a timely manner, remaining in a passive, delayed stage of human intervention and maintenance prevention. Currently, vehicles have the advantage of interconnected resources between people, vehicles, and platforms, but the eCall system does not maximize the use of its vehicle-to-everything (V2X) network resources for early warning of signs of spontaneous combustion. Existing cell-level safety monitoring and sensing technologies for spontaneous combustion warning are in the cutting-edge research and development stage, are difficult to implement, and impose high costs on users.

[0046] Therefore, this application provides an eCall emergency call system and vehicle, which can effectively improve the safety of new energy vehicles, especially by improving the safety of new energy vehicles through spontaneous combustion warning. Moreover, this application is low in cost, simple to implement, and can achieve the natural warning function without damaging the structure of the existing eCall emergency call system.

[0047] The structure of the eCall emergency call system will be described below with reference to some specific embodiments.

[0048] Figure 1 A schematic diagram of an eCall emergency call system according to an embodiment of this application is shown. Exemplarily, the eCall emergency call system (referred to as eCALL system 100) includes: an emergency call device 110 and at least two gas detection modules 120; the emergency call device 110 includes an emergency call main component 111 and a device housing 112.

[0049] The gas detection module 120 includes a gas sensor 122, an analog-to-digital converter chip 123, and a module processor 124, which are fixedly disposed within the module housing 121; the gas sensor 122 is connected to the module processor 124 through the analog-to-digital converter chip 123.

[0050] The module processor 124 communicates with the emergency call main component 111 through a preset data bus, through a through hole in the module housing 121, and through a through hole in the device housing 112.

[0051] The emergency call main unit 111 receives target electrical signals obtained by at least two gas sensors 122 based on the corresponding target gas detection, and determines whether to alarm based on the at least two target electrical signals.

[0052] In this embodiment, the emergency call main component 111 is also used to realize traditional basic functions such as collision detection, airbag detection, and real vehicle emergency call.

[0053] Six warning signs that a car may spontaneously combust include: unusual odor, abnormal instrument panel displays, abnormal discharge, overheat warnings, smoke emission, and difficulty starting or noticeable vibration. Among these, the unusual odor may be a plastic or rubber smell emanating from abnormal heat generated by the circuitry or battery, primarily composed of volatile organic compounds (VOCs). VOCs include formaldehyde, benzene, toluene, xylene, acetaldehyde, acrolein, and sulfur-containing compounds. For example, when a new energy vehicle battery spontaneously combusts, the smoke released mainly consists of fluorides and hydrocarbons (such as alkanes, alkenes, and alkynes).

[0054] This application uses gas sensing technology to detect abnormal odors and smoke, and monitors the release of gases in real time based on their type and concentration. Once the concentration of other gases reaches a dangerous threshold, an on-site alarm is activated, or an eCall rescue service (including GPS positioning and voice call service) is provided to the user.

[0055] Exemplary, at least two gas detection modules 120 are fixedly installed at least once in the driver's cab, near the vehicle battery, or in the front compartment of the vehicle, for detecting target gases and smoke in the driver's cab, near the vehicle battery, and in the front compartment of the vehicle. Among them, the gas detection module 120 fixedly installed in the driver's cab includes, but is not limited to, being installed below the steering wheel and above the driver's knee.

[0056] In this embodiment, a gas detection module 120 can be added externally to the existing eCALL system without damaging its structure. This method is simple and inexpensive. Under normal circumstances, it can monitor the air quality inside the car in real time. In case of an emergency, it can monitor signs of gas release before a car spontaneously combusts, and then play an alarm on-site via speaker or remotely report a car fire warning, maximizing the expansion of the existing eCALL system's functional options.

[0057] In one implementation, such as Figure 2 As shown, each gas detection module 120 includes a PCB board 126 and a signal socket 127; the signal socket 127, gas sensor 122, analog-to-digital converter chip 123 and module processor 124 are fixedly soldered onto the PCB board 126; the PCB board 126 is fixedly connected to the module housing 121 by a fixing component; exemplary, the fixing component includes, but is not limited to, screws and bolts.

[0058] The module housing 121 has a through hole at the position corresponding to the signal socket 127, so that the signal plug can pass through the through hole and connect to the signal socket 127.

[0059] Furthermore, the module processor 124 is specifically connected to the RS-485 data cable via the signal socket 127, and passes sequentially through the module housing 121 and the device housing 112, and is connected to the emergency call main component 111 via the peripheral component interface, serial port and RS-485 converter, and serial data cable. Among them, the peripheral component interface includes, but is not limited to, the RS485 interface, also known as the X1 interface.

[0060] The signal interface plug on the RS-485 data cable is connected to the signal socket 127, and the other end of the RS-485 data cable is connected to the peripheral component interface.

[0061] In one embodiment, the at least two gas detection modules 120 include a volatile organic compound (VOC) gas detection module and an electrochemical gas detection module. Exemplarily, one VOC gas detection module is installed in the driver's cab, near the vehicle battery, and in the front compartment of the vehicle; one electrochemical gas detection module is installed in the driver's cab.

[0062] The volatile organic compound gas detection module includes a gas sensor (referred to as VOC gas sensor 1221) for detecting volatile organic compound gases; the electrochemical gas detection module includes an electrochemical gas sensor 1222.

[0063] Furthermore, such as Figure 3 As shown, the electrochemical gas detection module also includes an analog front-end chip 125;

[0064] The analog front-end chip 125 is used to receive the current signal collected by the electrochemical gas sensor 1222, amplify and process it, and then output an analog voltage signal.

[0065] The electrochemical gas sensor 1222 is connected in sequence to the analog front-end chip 125 and the analog-to-digital converter chip 123 for communication.

[0066] Analog-to-digital converter chip 123 is connected to module processor 124 via SPI data line;

[0067] The module processor 124 also communicates with the analog front-end chip 125 via an IIC data line to configure the amplification gain of the analog front-end chip 125 and simultaneously receive the digital signal output from the analog-to-digital converter chip 123. The analog front-end chip 125 is a Texas Instruments (TI) LMP91000SD model, responsible for amplifying the weak current signal detected by the electrochemical sensor and outputting an analog voltage signal V. This analog voltage signal has a linear relationship with the gas concentration detected by the electrochemical sensor. The amplification gain of the operational amplifier integrated in the analog front-end chip 125 is programmable by the module processor 124 (MCU). The analog front-end chip 125 transmits the analog voltage signal to the analog-to-digital converter chip 123. The analog-to-digital converter chip 123 (ADC) converts the analog voltage signal into a digital signal to enhance the anti-interference capability during the transmission of weak level signals. The ADC chip 123 then transmits the digital signal to the device processor via the module processor 124. For example, the ADC chip 123 may be an ADS8350 model.

[0068] Furthermore, such as Figure 4 As shown, the gas sensor in the volatile organic compound gas detection module is connected to the module processor 124 via an analog-to-digital converter chip 123 and an SPI data line. The analog-to-digital converter chip 123 is used to convert the resistance signal of the gas sensor based on the detection of the target gas into an electrical signal, which is then transmitted to the module processor 124 via the SPI data line.

[0069] The VOC gas sensor 1221 outputs an analog voltage signal V_analog based on the detected target gas and transmits it to the analog-to-digital converter chip 123. The analog-to-digital converter chip 123 converts the analog voltage signal into a digital signal and sends it to the module processor 124. The module processor 124 sends the digital signal to the device processor via the SPI data line for determining whether to trigger an alarm. For example, the analog-to-digital converter chip 123 is an ADC161S626 model chip.

[0070] The preferred gas sensors in this application include a combustion-type VOC gas sensor 1221 and an electrochemical gas sensor 1222.

[0071] VOCs are volatile gases that can burn under specific conditions. Purification processes typically employ catalytic combustion. This principle is also used in VOC detection methods, known as the catalytic combustion VOC gas sensor 1221. The types of gases detected by the combustion-type VOC gas sensor 1221 include methane, propane, butane, n-pentane, nonane, acetylene, ethylene, isobutene, as well as carbon monoxide and hydrogen, as shown in Table 1.

[0072] When a combustible gas or volatile organic compound enters the combustion-type VOC gas sensor 1221, the gas being measured undergoes flameless combustion under the action of a catalytic material. The resistance of the detection electrode is a thermistor, and its resistance value changes linearly with the concentration of the gas being measured. The gas concentration can be calculated by using the Wheatstone bridge principle.

[0073] Table 1 Sensors and Detected Gas Types

[0074]

[0075] Electrochemical sensors, also known as current-gas sensors or miniature fuel cells, as shown in Table 1, are used to detect gases such as carbon monoxide, sulfur dioxide, formaldehyde, toluene, hydrogen, oxygen, and hydrogen fluoride. The gas being measured crosses the barrier region at the sensor head and diffuses into the electrochemical sensor, where it undergoes oxidation or reduction reactions under the catalytic action of the sensing electrodes. The carrier concentration during the chemical reaction is linearly related to the concentration of the gas being measured. The working electrode collects the generated current, which is then amplified by a subsequent operational amplifier (analog front-end chip 125).

[0076] Exemplarily, the electrochemical gas sensor is generally used to detect the oxygen content. The device processor monitors the air environment inside the vehicle based on this oxygen content. Specifically, based on the electrochemical reaction of oxygen on the electrode surface of the electrochemical gas sensor 1222, the change in oxygen concentration is monitored through the generated current signal. In special cases, both the electrochemical gas sensor 1222 and the VOC gas sensor 1221 are used to monitor the hydrogen content. The device processor uses this hydrogen content to implement a vehicle spontaneous combustion warning.

[0077] In one implementation, such as Figure 5 As shown, the emergency call main component 111 includes a device processor;

[0078] The module processor 124 communicates with the device processor through a preset data bus, passing through the module housing 121 and the device housing 112.

[0079] The device processor receives target signals from at least two gas sensors based on the corresponding target gases, and determines whether to trigger an alarm and the air quality level based on the at least two target electrical signals.

[0080] Furthermore, the emergency call main component 111 also includes an emergency button, a voice receiving device, a speaker, a GNSS antenna, and a communication module that are communicatively connected to the device processor;

[0081] The device processor is used to determine the alarm based on the target electrical signal, and after receiving the emergency signal from the emergency button and voice receiving device, it plays an alarm prompt through a speaker and sends emergency assistance information to an external rescue center through a communication module. The voice receiving device includes, but is not limited to, a microphone.

[0082] Furthermore, the emergency call main component 111 includes a battery module.

[0083] The battery module is also used to connect to at least two gas detection modules 120 and to power the at least two gas detection modules 120. The battery module is also used to power the emergency call main unit 111.

[0084] Each gas sensor is designed as a module as an external accessory. The module processor 124 outputs the gas concentration value, which is then aggregated via RS-485 and sent to the device processor of the eCALL device. The device processor then compares the collected gas concentration values ​​and durations with the set threshold to determine whether to activate the early warning alarm.

[0085] This application has the following advantages:

[0086] 1) This application utilizes the resources of the existing eCALL system and connects the gas detection module via peripheral accessories, thereby conveniently expanding the functionality of the existing eCALL system;

[0087] 2) This application utilizes the existing eCALL emergency call system to achieve vehicle fire early warning at minimal cost;

[0088] 3) This application utilizes the eCALL emergency call system to monitor the gas environment inside the vehicle, preventing harm to human health;

[0089] 4) This application utilizes the existing eCALL emergency call system to detect the oxygen content in the vehicle and provide early warning of oxygen deprivation accidents caused by children being locked in the car;

[0090] In summary, this application takes a different approach by using a gas sensor to maximize the use of the hardware and software resources in the existing eCALL system, achieving a wide range of applications at low cost and enriching the functionality of the existing eCALL system.

[0091] This application also provides a vehicle, exemplary, comprising: a vehicle body and an eCall emergency call system as provided in the first aspect of this application.

[0092] It is understood that the device in this embodiment corresponds to the eCall emergency call system in the above embodiment, and the options in the above embodiment are also applicable to this embodiment, so they will not be described again here.

[0093] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
