Automatic identification system and automatic identification method for mounting angle of early-warning device for vehicle driving

Abstract

The invention discloses an automatic identification system and an automatic identification method for the mounting angle of an early-warning device for vehicle driving. The system comprises a GPS (global positioning system) module, a GSensor module, an MCU (micro controller unit) and a main control processor. The GPS module is used for collecting longitude and latitude, speed and angular separation information of the early-warning device. The GSensor module is used for collecting acceleration magnitudes in three directions on an internal coordinate system therein in real time. The MCU is used for collecting data of the GPS module and the GSensor module in real time and sending the data to the main control processor. The main control processor is used for calculating axis angles of an xyz natural coordinate system in the forward direction of a vehicle according to the received data so as to automatically identify and calibrate the mounting angle of the early warning device. The automatic identification system and the automatic identification method have the advantages that direction data and braking data which are collected by the GPS module and an acceleration sensor are analyzed, and the mounting angle of the early-warning device as well as the axis angles between xyz axes of the acceleration sensor and a vehicle coordinate system are calculated, so that requirements on the mounting angle of the early-warning device are not needed, the early-warning device can be put flat or laterally, and operators operate the early-warning device simply, conveniently and rapidly.

Description

technical field [0001] The invention relates to a vehicle-mounted terminal, in particular to a system and method for automatically identifying the installation angle of a vehicle driving warning device. Background technique [0002] With the rapid growth of China's economy, the number of cars in China increases by millions every year. With the increase of road vehicles, the driver cannot in time discover the danger of rear-end collision with the vehicle in front due to fatigue, negligence and other reasons, causing rear-end collision accidents to occur from time to time. [0003] In order to improve the safety of driving, the MCU on the device side is often used to collect the vehicle's switch value (brake, turn signal, etc.), AD (fuel level), GPS data, and data on the CAN bus of the car. The device side uses an intelligent algorithm to judge the current driving. Whether the behavior is within a reasonable range, and then through data storage or remote transmission to the b...

[0004] However, the existing system and algorithm are too complicated, and there are strict requirements on the installation position and direction of the equipment in the vehicle. At the same time, after the installation is completed, the parameter settings and requirements are set according to the installation position. In this way, the installation and construction personnel It will be impossible to start, the operation is extremely complicated, and it is easy to fail to apply due to improper settings
