Abstract

The embodiment of the present application is applicable to the technical field of vehicle attitude detection, and provides a vehicle attitude detection method, device, vehicle-mounted terminal, vehicle and medium, the method includes: receiving the first acceleration value of the target axis output by the inertial navigation module, wherein , when the inertial navigation module is in a horizontal state, the acceleration direction of the target axis is the same as the direction of gravity acceleration; if the first acceleration value of the target axis is less than a preset threshold value, it is detected that the first A plurality of acceleration values ​​of the target axis within a preset time period after the acceleration value; if the plurality of acceleration values ​​are all less than the preset threshold, it is determined that the vehicle rolls over. The attitude detection process algorithm of this embodiment is simple to implement and reduces the complexity of the detection algorithm design. After the abnormality is detected, multiple detections and confirmations are carried out over a long period of time, which solves possible misjudgments on bumpy road sections and has high reliability.

Description

technical field [0001] The present application belongs to the technical field of vehicle posture detection, and in particular relates to a vehicle posture detection method, device, vehicle-mounted terminal, vehicle and medium. Background technique [0002] Vehicle attitude detection is a technology that detects the vehicle attitude in real time during the driving process and determines whether the vehicle has a rollover accident. By accurately detecting the occurrence of rollover accidents, it is possible to send warning information to the Internet of Vehicles system in time and speed up the rescue response. [0003] In the prior art, vehicle posture detection mainly uses an acceleration sensor to calculate the angle between acceleration and gravitational acceleration, and then combine positioning information or vehicle information to identify the posture of the vehicle during driving and determine whether the vehicle has rolled over. For example, the acceleration values ​​...
