Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the context of existing technologies, users often lack the relevant professional knowledge to handle emergency collisions or serious traffic accidents, which can easily lead to secondary risks in rescue measures and on-site handling of people / vehicles, and delay rescue time. With the implementation of the new national standard for electric bicycles (GB17761-2024), the country is paying more and more attention to the safety of electric two-wheeled and three-wheeled vehicles. The addition of Beidou positioning function to vehicles makes it possible to accurately perceive the detailed location of the vehicle.

[0022] This application uses sensing devices such as collision sensors, speed sensors, and gyroscopes on the electric two-wheeled vehicle to continuously monitor the vehicle's dynamic information. When information exceeding a preset threshold is detected, a "serious collision has occurred" signal is triggered. After the electric bicycle is equipped with a 2G / 4G IoT network communication module, it can support the vehicle to send its real-time status to the cloud platform through the 2G / 4G network channel. The cloud platform service triggers corresponding call and rescue services through the perception strategy model.

[0023] The following explains the technical terms used in this application: Impact acceleration: the rate of change of velocity per unit time, is a vector, and is usually expressed in units of gravitational acceleration g (9.8 m / s²). Impact duration: The time it takes for a vehicle's speed to decrease from its peak to near a standstill during an emergency collision. Impact acceleration threshold: The signal value detected by the collision sensor. Users can customize the corresponding threshold to determine whether a collision has occurred and classify the severity of the collision based on the value range. Roll angle threshold: The signal value detected by the gyroscope sensor. Users can define a corresponding threshold to determine whether the vehicle has rolled over. The severity of the rollover is divided according to the data range and is ultimately reflected in the system integral deflection angle. Pitch angle threshold: The signal value detected by the gyroscope sensor. Users can define a corresponding threshold to determine whether the vehicle is pitching forward or backward, and classify the severity of pitching forward or backward according to the data range. The final result is reflected in the system integral yaw angle. Emergency collision response: The corresponding operational actions taken when the system detects that the fusion and aggregation of the collected data has triggered an "emergency collision". Call strategy: It is composed of the cross combination of "emergency collision event" and "emergency collision measure" and is used to describe what action to take after what event occurs. It is the core perception and decision-making unit in the emergency call scenario.

[0024] To facilitate understanding of this embodiment, the embodiments of the present invention will be described in detail below.

[0025] Example 1: Figure 1 This is a flowchart of an emergency call control method for electric vehicles provided in Embodiment 1 of the present invention.

[0026] Reference Figure 1 The method includes the following steps: Step S101: Obtain the multi-level exclusive emergency collision mode and emergency call emergency measures generated by the user in the client configuration; Step S102: The client binds the multi-level exclusive emergency collision mode and emergency call emergency measures to generate a call strategy; Step S103: The client synchronizes the call policy to the vehicle system; Step S104: When the user drives the vehicle, collect the vehicle's parameter information; Step S105: Match the parameter information with the call strategy to calculate the emergency collision level; wherein, the parameter information includes the current impact acceleration, current roll angle, current pitch angle and current yaw angle; Specifically, impact acceleration is the rate of change of velocity per unit time, with units of . In this application, the impact acceleration is ultimately expressed as gravitational acceleration ( = 9.8 The unit is ). Refer to formula (1): (1) in, Indicates the speed increment. Indicates the time increment. It represents the acceleration due to gravity.

[0027] Refer to formulas (2) and (3): (2) in, This indicates the velocity value at the time of calculation. This represents the velocity value at the time of the last calculation.

[0028] (3) in, Indicates local calculation time. Indicates the time of the last calculation.

[0029] Refer to formula (4): (4) Once the impact acceleration is determined, the probability of injury can be determined, as detailed in the following reference. Figure 2 .

[0030] The roll angle is the change in angle per unit time. Data is collected by a six-axis gyroscope sensor. For two-wheeled vehicle scenarios, a frequency of 100~200Hz is sufficient (i.e., a collection interval of 5~10ms). This frequency mode can detect sudden rollovers and collisions without significantly putting pressure on the system's computational performance. The power consumption caused by this frequency band is also relatively low. The calculation formula is: use the current angular velocity to perform integral model calculation every 5ms. Refer to formula (5): (5) in, This represents the deflection angle at time t. Indicates the initial deflection angle. Represents the angular velocity at time t. Let t be the time interval from the start time to time t.

[0031] In this scenario, we consider the angular offsets in the x-axis (corresponding to lateral roll) and y-axis (corresponding to forward and backward roll), while the z-axis (corresponding to spinning in place) is not considered for the time being. Refer to formulas (6) and (7): (6) in, This represents the deflection angle of the x-axis at time t. This represents the initial x-axis deflection angle. This represents the angular velocity along the x-axis at time t. The time interval is from the start time to time t.

[0032] (7) in, This represents the y-axis deflection angle at time t. This represents the initial y-axis deflection angle. This represents the angular velocity along the y-axis at time t. This represents the time interval from the start time to time t. Subsequently, strategy matching is performed according to the level; see [link / reference] for details. Figure 3 .

[0033] Reference Figure 4 This is an emergency collision level that combines impact acceleration and roll angle. (Refer to...) Figure 5 This is an emergency collision handling strategy.

[0034] Step S106: Select the corresponding emergency measures according to the emergency collision level; Step S107: Implement the corresponding emergency strategy according to the emergency measures.

[0035] Furthermore, step S101 includes the following steps: Step S201: Obtain the multi-level exclusive emergency collision mode generated after the user configures it on the emergency call accident definition configuration page of the client; Step S202: Obtain the emergency call measures generated after the user configures them on the emergency call measures configuration page of the client.

[0036] Furthermore, the multi-level exclusive emergency collision mode includes impact acceleration threshold, roll angle threshold, pitch angle threshold, and yaw angle threshold; Emergency call measures include setting up emergency call contacts and contact plans, setting up one-click emergency call assistance, and setting up one-click call service center voice confirmation.

[0037] Furthermore, the method also includes the following steps: Step S301: The vehicle system connects to the cloud platform via the 4G network module and receives policy configuration information sent by the cloud platform. In step S302, the vehicle system synchronizes the policy configuration information to the local policy information.

[0038] Furthermore, step S107 includes the following steps: Step S401: When the emergency measure is to directly call for emergency rescue, call for rescue directly through the IoT card of the vehicle system; Step S402: When the emergency measure is to contact the emergency contact, the emergency contact is directly called through the IoT card of the vehicle system. Step S403: When the emergency measure is to call the car manufacturer's customer service center, the customer service center is directly called through the IoT card of the vehicle system.

[0039] The advantages of this application are: 1) Users can pre-set threshold values ​​for parameters such as impact acceleration, roll angle, pitch angle, and yaw angle for the "serious collision has occurred" scenario via a mobile app based on their own vehicle model and driving habits. 2) Users can pre-set emergency measures after a collision via a mobile app, including on-site confirmation call, calling emergency contacts, and one-click medical assistance; 3) Based on the scenario model preset by the APP, when the vehicle system collects parameters and triggers a collision scenario, it will automatically trigger an emergency call and report core information such as vehicle identification, current system time, detailed vehicle location information, collision severity, number of riders at the time of the collision, and vehicle load to the cloud backend to generate an emergency call event to assist subsequent rescue decisions. 4) Voice interaction devices based on the vehicle's microphone and speakers assist the call center in remotely confirming problems, providing on-site feedback, and offering rescue guidance to users; 5) Automotive customer service personnel rely on the digital platform to quickly make authorized and reasonable rescue decisions based on user feedback and call event reporting data, and contact medical assistance and formulate subsequent vehicle maintenance and after-sales plans according to the degree of urgency; 6) An emergency "one-click rescue" physical button is set in a hidden position on the side of the vehicle's dashboard, making it convenient for users to trigger "emergency rescue" in an emergency.

[0040] Example 2: Figure 6 This is a flowchart of another emergency call control method for an electric vehicle provided in Embodiment 2 of the present invention.

[0041] Reference Figure 6 The method includes: Users log in to the APP with their personal accounts, bind their personal vehicle information, and add information such as the name and phone number of their personal emergency contact. Enter the APP emergency call accident definition configuration page, create a new accident definition item, and configure the corresponding impact acceleration threshold, roll angle threshold, pitch angle threshold, accident level and yaw angle threshold for the call under the accident item; Enter the emergency call measures configuration page of the APP, select the accident level that has been added, and configure the corresponding one-click rescue, one-click call to emergency contacts, and one-click call to the car manufacturer's customer service center under the measures item. Only one of the three can be selected. After configuring the mobile app, you can synchronize the call policy to the vehicle system by clicking the "Synchronize vehicle-side emergency call policy" configuration button. With the 4G network module connected to the cloud platform, the vehicle system receives policy configuration information from the cloud platform and updates the local policy information of the vehicle system synchronously. When the user starts and drives the vehicle, the six-axis gyroscope collects angular velocity according to the acquisition frequency, and the Hall sensor collects signals according to the acquisition frequency. The deflection angle and impact acceleration are calculated based on the system time of multiple acquisitions. The calculated impact acceleration and deflection angle are matched with the call strategy to calculate the emergency collision level (accident level), and the corresponding emergency measures are selected according to the emergency collision level. The calculated accident level, system time, deflection angle, acceleration, GPS latitude and longitude information, vehicle identification and other key information are integrated and uploaded to the cloud platform via the network or SMS through T-Box; If the emergency measure is to directly call for emergency rescue, then the rescue can be called directly through the IoT card of the vehicle's infotainment system. If the emergency measure is to contact an emergency contact, then the emergency contact will be called directly through the vehicle's IoT card. If the emergency measure is to call the car manufacturer's customer service center, then the call can be made directly through the vehicle's IoT card. If a problem is reported by calling the customer service center, the car company's customer service personnel will confirm the problem with the on-site staff and formulate a follow-up after-sales maintenance plan.
