Tilt 31 and tilt 32 can come from the same tilt sensor. In other words, the inclination angle 31 and the inclination angle 32 can come from a dual-axis inclination sensor.

Due to factors such as the production tolerance of the two-wheeled vehicle and the difference in the user's installation technology, the installation position of the inclination sensor on different two-wheeled vehicles may be different, resulting in inaccurate sensing data (ie: inclination angle) of the inclination sensor . In order to solve the above problems, the tilt sensing module 121 can perform self-calibration before receiving the sensing data from the tilt sensor, so that the interpretation of the sensing data by the tilt sensing module 121 will not be disturbed by external factors. For example, the inclination sensing module 121 can be communicatively connected to the electronic control system of the two-wheel vehicle 50 through the transceiver 130 . When the two-wheel vehicle 50 starts, the inclination sensing module 121 can receive the start signal from the electronic control system, and according to the start signal self-calibration for moving signals.

In one embodiment, the vehicle speed detection module 122 can receive a global positioning system (GPS) signal through the transceiver 130 . The vehicle speed detection module 122 can calculate the vehicle speed of the two-wheeled vehicle 50 according to the GPS signal. In one embodiment, the vehicle speed detection module 122 can communicate with the accelerometer disposed on the two-wheel vehicle 50 through the transceiver 130 to obtain the acceleration of the two-wheel vehicle 50 from the accelerometer. The vehicle speed detection module 122 can calculate the vehicle speed of the two-wheel vehicle 50 according to the acceleration of the two-wheel vehicle 50 . In one embodiment, the vehicle speed detection module 122 can 130 is communicatively connected to the rotational speed sensor arranged on the gearbox or the axle of the two-wheeled vehicle 50 to obtain the rotational speed of the two-wheeled vehicle 50 from the rotational speed sensor. The vehicle speed detection module 122 can calculate the vehicle speed of the two-wheel vehicle 50 according to the rotation speed of the two-wheel vehicle 50 and the diameter of the tire.

After obtaining the inclination difference corresponding to the rotation axis 21 (hereinafter referred to as "inclination difference α"), the inclination difference corresponding to the rotation axis 22 (hereinafter referred to as "inclination difference β") and the vehicle speed of the two-wheeled vehicle 50 Finally, the driving behavior judging module 123 can judge the driving behavior of the two-wheeled vehicle 50 according to the inclination angle difference α, the inclination angle difference β or the vehicle speed, wherein the driving behavior can include sharp turns, snaking, dumping, collision or high-speed driving over unevenness section etc.

When the two-wheeled vehicle 50 is turning, the vehicle body will tilt to generate a tilt angle difference α. Assuming that the inclination angle difference α is zero when the two-wheeled vehicle 50 is not tilted, the driving behavior judgment module 123 can judge whether the two-wheeled vehicle 50 is turning left or right according to the positive or negative of the inclination angle difference α. When making a sharp turn, the vehicle speed of the two-wheeled vehicle 50 will be greater than a certain speed. Accordingly, the driving behavior judging module 123 can judge that the driving behavior is " sharp turn".

When the two-wheel vehicle 50 is snaking, the two-wheel vehicle 50 will tilt left and right many times in a short period of time. Accordingly, the driving behavior judging module 123 can judge in response to the number of times the inclination angle difference α exceeds the difference threshold value (for example: 15 degrees) per unit time (for example: 10 seconds) is greater than the number of times threshold (for example: 3 times) Driving behavior is snaking. On the other hand, snaking can also be defined by vehicle speed.

The main feature of the dumping event is that the vehicle body of the two-wheeled vehicle 50 is dumped substantially when the event occurs. Accordingly, the driving behavior judging module 123 can judge the driving behavior as dumping in response to the inclination angle difference α exceeding the difference threshold value (for example: 70 degrees). In addition, when the two-wheeled vehicle 50 falls, the vehicle speed of the two-wheeled vehicle 50 is usually static. Accordingly, the driving behavior judging module 123 can judge that the driving behavior is “dumping” in response to the inclination angle difference α exceeding the difference threshold and the vehicle speed being less than the vehicle speed threshold (for example: 5 km/h).

When the two-wheeled vehicle 50 collides, the two-wheeled vehicle 50 may be affected by external forces from different directions, causing multiple inclination angles of the two-wheeled vehicle 50 to change without warning. Accordingly, the driving behavior judging module 123 can judge the driving behavior in response to the inclination difference α exceeding the first difference threshold (for example: 45 degrees) and the inclination difference β exceeding the second difference threshold (for example: 15 degrees). Behavior is "collision".

When the two-wheeled vehicle 50 travels at a high speed through a pothole or an uneven section of a deceleration hill, the two-wheeled vehicle 50 will fall forward or backward. Accordingly, the driving behavior judging module 123 can judge that the driving behavior is "driving through an uneven road section at high speed" in response to the inclination angle difference β exceeding the difference critical value (for example: 10 degrees) and the vehicle speed being greater than the vehicle speed critical value (for example: 60 kilometers).

The driving behavior collection module 221 of the remote server 200 can receive information such as the inclination difference α, the inclination difference β, vehicle speed or driving behavior through the transceiver 230 . The alarm module 222 of the remote server 200 can output a warning message corresponding to the driving behavior through the transceiver 130 to remind the user of the remote server 200 . The user can try to contact the driver according to the warning message to confirm the safety of the driver. Specifically, the warning module 222 can be communicatively connected to the output device through the transceiver 230, and output the warning message through the output device.
