Description

Technical Field

[0001] This utility model belongs to the field of vehicle-mounted AECS technology, specifically relating to a vehicle-mounted AECS system integrated with IVI. Background Technology

[0002] In the prior art, the specific structure of an in-vehicle AECS (Automotive Emergency Call System) is as follows: Figure 1 As shown, there are two specific alarm processes: 1. In the event of a severe collision or rollover, the ACU (Airbag Control Unit) located beneath the vehicle will immediately transmit the "collision event" and "rollover event" to the AECS terminal via CAN signal. Upon receiving the collision signal from the ACU, the AECS terminal will be immediately activated. It will quickly acquire the vehicle's precise GPS location information via the 4G & positioning antenna module. The AECS terminal will package key information such as the "accident occurred" event type, vehicle location, and vehicle VIN code, preparing to initiate an emergency call. The AECS terminal will send a "transmission mute command" to the IVI (In-Vehicle Infotainment System) via the "CAN / hardware" line to maintain a quiet environment inside the vehicle. The AECS terminal will automatically call the preset emergency rescue center via the 4G network and further establish telephone communication with the rescue center via MIC (microphone) and a dedicated speaker.

[0003] 2. When no collision occurs, the driver manually presses the SOS button on the button / indicator module to transmit the alarm command directly to the AECS terminal via hardwire. The AECS terminal is then manually activated, and the subsequent process is similar to that of automatic triggering: obtaining location information, calling the emergency center, and establishing a two-way voice call via the microphone and speaker to achieve emergency assistance. However, existing in-vehicle AECS systems rely on independent communication and positioning terminals, resulting in higher costs and more dispersed structures, leading to reduced space utilization.

[0004] A new in-vehicle AECS system is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide an in-vehicle AECS system that integrates with IVI, in order to solve the technical problems of high cost and low space utilization in existing AECS systems.

[0010] Preferably, the IVI system further includes a positioning module for acquiring the vehicle's geographical location information; GPS and BeiDou positioning are used.

[0011] Preferably, the IVI system also includes a backup battery for powering the alarm module, voice communication module, and positioning module.

[0012] The beneficial effects of this utility model are as follows: The vehicle's geographical location information is obtained by setting a vehicle positioning unit and sent to the IVI system; the active alarm unit identifies the user's control intent and converts it into corresponding control commands, which are then sent to the IVI system; the ACU in the automatic alarm unit detects the vehicle's safety status and sends vehicle collision events to the IVI system; the IVI system integrates an alarm module and a voice communication module to process the received data, i.e., transmits the alarm data to the rescue center through the alarm module; and enables two-way voice communication between the vehicle and the rescue center through the voice communication module.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figure 2 As shown, this utility model discloses an in-vehicle AECS system integrated with IVI, comprising: The vehicle positioning unit is used to acquire the vehicle's geographical location information and send it to the IVI system; the vehicle positioning unit uses GPS and Beidou positioning, which is accurate.

[0016] The active alarm unit is used to identify the user's control intent and convert it into corresponding control commands to send to the IVI system; the active alarm unit uses buttons and indicator lights.

[0017] The automatic alarm unit is used to detect the vehicle's safety status through the ACU and send vehicle collision events to the IVI system; The IVI system includes an alarm module and a voice communication module. The alarm module processes received data, transmitting alarm data to the rescue center. The voice communication module enables two-way voice communication between the vehicle and the rescue center. The IVI system also includes a positioning module and a backup battery. The positioning module acquires the vehicle's geographical location information using GPS and BeiDou positioning. The backup battery powers the alarm, voice communication, and positioning modules, ensuring the onboard AECS system continues to function and alarm data is transmitted correctly in the event of a power outage after an accident. The voice communication module includes an audio amplifier, microphone, ADC / DAC, and speaker. The microphone captures voice data, the ADC converts the voice to a digital signal, the DCA converts the digital signal back to an analog signal, and the audio amplifier drives the speaker for two-way voice communication between the vehicle and the rescue center.

[0018] The vehicle positioning unit and the active alarm unit are connected to the IVI system via hard wiring, and the ACU in the automatic alarm unit is connected to the IVI system via a CAN bus.

[0019] The vehicle's geographical location information is obtained by setting up a vehicle positioning unit and sent to the IVI system. The active alarm unit recognizes the user's control intention and converts it into corresponding control commands, which are then sent to the IVI system. The ACU in the automatic alarm unit detects the vehicle's safety status and sends vehicle collision events to the IVI system. The IVI system integrates an alarm module and a voice communication module to process the received data, i.e., transmitting alarm data to the rescue center through the alarm module; and enabling two-way voice communication between the vehicle and the rescue center through the voice communication module. By utilizing the existing IVI system, the vehicle's AECS-related functions can be implemented, eliminating the structural costs of setting up a separate AECS terminal, microphone, and dedicated speaker, and improving the space utilization of the vehicle's AECS system.

[0020] Example 1: The technical solution for automatically triggering the alarm is as follows: In the event of a severe collision or rollover, the ACU (Airbag Control Unit) located beneath the vehicle immediately transmits the "collision event" and "rollover event" information to the IVI (In-Vehicle Response) system via CAN signal. Upon receiving the collision signal from the ACU, the IVI system quickly obtains the vehicle's precise geographical location information using GPS and BeiDou positioning. The alarm module packages key information such as the "accident occurred" event type, vehicle location, and vehicle VIN code, and transmits the alarm data to the rescue center. Furthermore, the IVI system's voice communication module collects voice data via its microphone (MIC), which is then converted to a digital signal by an ADC (Analog Converter) and then to an analog signal by a DCA (Digital Converter). This analog signal is then amplified by an amplifier to drive the speaker, enabling two-way voice communication between the vehicle and the rescue center. The microphone and dedicated speaker establish telephone communication with the rescue center. Additionally, the IVI system includes a positioning module and a backup battery. The positioning module addresses the technical issue of failed vehicle positioning data acquisition when the vehicle positioning unit malfunctions. The backup battery powers the alarm module, voice communication module, and positioning module, ensuring the onboard AECS (Airbag Control System) continues to function normally and that vehicle alarm data can be transmitted correctly in the event of a power outage after an accident.

[0021] The technical solution for manually triggering the alarm is as follows: The driver manually presses the SOS button on the button / indicator module to send the alarm command to the IVI system via the CAN bus. Upon receiving the collision signal from the ACU, the IVI system quickly obtains the vehicle's precise geographical location information using GPS and BeiDou positioning. The alarm module packages key information such as the "accident has occurred" event type, vehicle location, and vehicle VIN code, and transmits the alarm data to the rescue center. Further, the IVI system's voice communication module collects voice data via the microphone (MIC), the ADC converts the voice to a digital signal, and the DCA converts the digital signal to an analog signal. This analog signal is then driven by a sound amplifier to drive the speaker, enabling two-way voice communication between the vehicle and the rescue center. The microphone and dedicated speaker establish telephone communication with the rescue center. Additionally, the IVI system includes a positioning module and a backup battery. The positioning module addresses the technical problem of failed vehicle positioning data acquisition when the vehicle positioning unit malfunctions. The backup battery powers the alarm module, voice communication module, and positioning module, ensuring the onboard AECS system continues to function normally and alarm data can be transmitted normally in the event of a power outage after an accident.
