[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.
[0026] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own emphasis, and for parts not described in detail in one embodiment, reference can be made to the relevant description of other embodiments.
[0027] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0028] Reference Figure 1 , an emergency call system based on a vehicle-mounted eCall device, includes a power monitoring unit 1, a collision sensor 2, a seat sensor 3 and an eCall module 4.
[0029] Specifically, the power monitoring unit 1 is used to monitor the power mode of the whole vehicle. The power monitoring unit 1 is an important component of the emergency call system, and its implementation method can adopt a power monitoring chip or module. In practical applications, a chip specially designed for vehicle power monitoring can be selected, which has a built-in power monitoring circuit and corresponding control logic. The implementation principle of the power monitoring unit 1 is mainly based on real-time monitoring of the power status of the whole vehicle. The unit detects the power mode of the vehicle, including startup, operation and shutdown states, to ensure the normal operation of the vehicle power supply. It should be pointed out that the control logic of power detection belongs to the conventional technical means in this field.
[0030] The collision sensor 2 is used to detect the acceleration of the vehicle body. As a key component of the emergency call system, the collision sensor 2 can generally be an acceleration sensor or an inertial sensor. This sensor detects whether a collision has occurred by monitoring the acceleration change of the vehicle body. A feasible embodiment is to install a high-sensitivity acceleration sensor at a key part of the vehicle, such as the front, rear or side. When the vehicle is hit, the sensor will sense the sudden acceleration change and pass this information to the eCall module 4.
[0031] The seat sensor 3 is used to detect whether there is someone sitting in the seat position. The seat sensor 3 in the emergency call system can usually be implemented using pressure sensing technology or infrared sensing technology. A common implementation is to install a sensor that can sense weight or pressure changes on the vehicle seat. Such a sensor can detect whether there is someone sitting in the seat, and determine whether the seat is occupied by sensing the deformation or weight change of the seat. Another implementation is to use an infrared sensor that can detect infrared radiation in the seat area. When someone approaches or sits on the seat, the infrared sensor can detect the change in heat and reflect the occupancy status of the seat.
[0032] These seat sensors 3 can be connected to the eCall module 4 to monitor the occupancy of the seat in real time. When the vehicle is powered on, the seat sensor 3 provides the eCall module 4 with information about whether the seat is occupied. When the seat is occupied, this information can be used as one of the conditions for triggering an emergency call, ensuring that the emergency call process is initiated in a timely manner when an accident occurs in the vehicle, thereby improving the accuracy of emergency safety response.
[0033] The eCall module 4 signal is connected to the power monitoring unit 1, the collision sensor 2 and the seat sensor 3, and is used to trigger the eCall module 4 when the vehicle power is off, there is someone in the seat and the acceleration exceeds a preset value.
[0034] Specifically, an embodiment of the eCall module 4 may include a device that integrates communication and control functions to automatically make calls and information transfers in emergency situations. The eCall module 4 may use advanced mobile communication technologies, such as cellular networks or satellite communications, to ensure timely and reliable communication with emergency service centers when an emergency occurs in the vehicle.
[0035] In some embodiments, the design of the eCall module 4 may take into account integration with the vehicle system to receive real-time data from the power monitoring unit 1, the collision sensor 2, and the seat sensor 3. When an accident triggering condition is detected, the eCall module 4 will automatically start the call process and send the vehicle location, accident type, and other relevant information to the emergency service center. At the same time, the eCall module 4 may also include voice communication or data transmission functions to facilitate real-time communication between passengers in the vehicle and the emergency service center.
[0036] The function of the eCall module 4 is to trigger the emergency call function when certain conditions are met. Specifically, the triggering conditions include the vehicle power being off, someone sitting in the seat, and the vehicle acceleration exceeding the preset value. When the system detects that these conditions are met at the same time, the eCall module 4 will start the emergency call process, notify the emergency service agency and provide vehicle-related information to respond to possible emergencies in a timely manner. This implementation method can cover a wide range of application scenarios and improve the active safety performance of the vehicle. When the vehicle is turned off and there are people in the car, the eCall module 4 can be triggered in the event of a collision, automatically dialing and calling for rescue, which is very beneficial to improving driving safety and mitigating the consequences of accidents.
[0037] Furthermore, as an embodiment of the present utility model, the power supply monitoring unit 1 is integrated into a body control unit of a vehicle.
[0038] Specifically, as an embodiment of the utility model, the power monitoring unit 1 is integrated into the vehicle's body control unit. This means that the power monitoring unit 1 is integrated with the vehicle's overall electronic control system, and through integration with the body control unit, it can interact more closely with the vehicle's power supply and operating status. This integrated design enables the power monitoring unit 1 to more accurately monitor the vehicle's power mode, obtain key information on the power status in real time, and quickly pass it to the eCall module 4 when necessary, to ensure accurate and timely emergency call response in emergency situations. This embodiment not only improves the efficiency of the system, but also simplifies the design and integration process of the vehicle system, making the vehicle more responsive in emergency situations.
[0039] Furthermore, as an embodiment of the present utility model, the system further includes: a positioning module 5, wherein the positioning module 5 is data-connected to the eCall module 4, and sends positioning information to the eCall module 4 when the eCall module 4 is triggered.
[0040] Specifically, in a further embodiment of the utility model, the system further includes a positioning module 5, the data of which is connected to the eCall module 4. When the eCall module 4 is triggered, the positioning module 5 sends the accurate location information of the vehicle to the eCall module 4. This design utilizes modern positioning technologies, such as global satellite navigation systems (such as GPS), to ensure that the geographic location of the vehicle can be quickly and accurately transmitted in an emergency. When an emergency occurs, in addition to carrying information related to the collision and seat status, the eCall module 4 can also provide real-time location data of the vehicle, which provides critical information for emergency services to help them carry out rescue operations more effectively. This comprehensive embodiment has significant advantages in improving the accuracy and reliability of the emergency call system, and helps to more effectively protect the safety of vehicle occupants.
[0041] Further, as an embodiment of the present utility model, the eCall module 4 includes a communication unit 6, and the communication unit 6 is data-connected to the positioning module 5, and is used to send the location information of the positioning module 5 to an external receiving unit when the eCall module 4 is triggered.
[0042] Specifically, in a further embodiment of the present invention, the eCall module 4 further includes a communication unit 6, and the data of the communication unit 6 is connected to the positioning module 5. When the eCall module 4 is triggered, the communication unit 6 plays a key role in sending the vehicle location information obtained by the positioning module 5 to an external receiving unit. The communication unit 6 uses advanced communication technology, such as cellular networks or satellite communications, to ensure that the positioning information is efficiently transmitted to the emergency service center or other relevant external receiving units.
[0043] Through this embodiment, the eCall system can not only obtain the vehicle's location information when triggered, but also quickly and reliably transmit this information to the outside, providing emergency service agencies with real-time and accurate vehicle location. This comprehensive design improves the system's response speed and the effectiveness of emergency calls, allowing emergency rescue personnel to locate the accident scene more quickly and improve the safety level of vehicle occupants in emergency situations.
[0044] Furthermore, as an embodiment of the present utility model, the eCall module 4 is also used to trigger the eCall module 4 when the vehicle power is on and the acceleration exceeds a preset value.
[0045] Specifically, in a further embodiment of the utility model, the eCall module 4 has an additional function, that is, when the power of the vehicle is turned on and the acceleration of the vehicle exceeds a preset value, the eCall module 4 is triggered. This design integrates the information of the power monitoring unit 1 and the collision sensor 2, so that the eCall system has more comprehensive triggering conditions. When the vehicle starts, the eCall module 4 monitors the power status of the vehicle and compares it with the acceleration data obtained in real time by the collision sensor 2. When the acceleration exceeds the preset value, the eCall module 4 will be activated, start the emergency call process, and send key accident information to the emergency service center.
[0046] This embodiment improves the comprehensiveness and accuracy of the eCall system by integrating power status and acceleration information, ensuring that emergency calls can be triggered promptly and accurately when an accident occurs while the vehicle is driving. This comprehensive triggering condition not only helps to improve the active safety performance of the vehicle, but also increases the applicability of the system in different emergency situations, providing more comprehensive protection for drivers and passengers.
[0047] Furthermore, as an embodiment of the present utility model, the collision sensor 2 controls the airbag connected to the vehicle body.
[0048] Specifically, in a further embodiment of the present invention, the collision sensor 2 further controls the airbag system connected to the vehicle body. This design enables the collision sensor 2 to control and connect with the airbag system of the vehicle body in real time when the collision of the vehicle is detected. When the collision sensor 2 is triggered, it will send a signal to the airbag system, prompting the airbag system to quickly inflate to provide additional protection, effectively reducing the damage to the driver and passengers in a collision accident.
[0049] This embodiment enhances the passive safety performance of the vehicle by tightly integrating the collision sensor 2 and the airbag system. The control connection of the collision sensor 2 enables the airbag to respond more accurately to different collision scenarios and provide more customized safety protection. This comprehensive design not only increases the response speed of the system, but also improves the passive safety performance of the vehicle in a collision accident, providing more comprehensive safety protection for the driver and passengers.
[0050] Furthermore, as an embodiment of the present invention, the system further includes an input unit, and the input unit is data-connected to the collision sensor 2 for inputting the preset value.
[0051] Specifically, in a further embodiment of the utility model, the system further comprises an input unit, which is data-connected to the collision sensor 2, and whose main function is to input a preset value. Through this design, the system can dynamically receive and adjust the preset value of the collision sensor 2 to adapt to different driving conditions or safety requirements. The data connection of the input unit ensures instant communication, so that the user or system administrator can flexibly set the threshold or preset value of the collision sensor 2 according to the actual situation.
[0052] This embodiment improves the flexibility and customizability of the system, allowing the user to adjust the sensitivity of the collision sensor 2 according to specific usage scenarios or driving requirements. By dynamically inputting preset values, the system can better adapt to different driving environments, thereby improving the effectiveness of the entire vehicle safety system. This comprehensive design helps to improve the applicability of the system and enable it to better meet the user's personalized and specific safety requirements.
[0053] Further, as an implementation mode of the present invention, the input unit data is connected to the eCall module 4, and is used to input the contact information when the eCall module 4 is triggered.
[0054] In a further embodiment of the present invention, the input unit is data-connected to the eCall module 4, and is mainly used to input the contact information to be used when the eCall module 4 is triggered. This design allows the user or system administrator to dynamically set the communication method or contact information that the eCall system should use after the emergency call is triggered in an emergency, such as a mobile phone number, email address or other relevant emergency contact information.
[0055] Through this implementation, users can specify how to communicate with emergency services or other relevant parties in an emergency according to personal preferences or actual needs. This customized contact input increases the flexibility and personalization of the system, ensuring that relevant personnel can be notified in the most appropriate way in an emergency. This comprehensive design helps to improve the user-friendliness of the system and make it closer to the actual needs of users, thereby improving the practicality and effectiveness of the entire eCall system.
