Abstract

The invention discloses a GPS (global position system)-based dangerous driving detection system which is implemented through setting an inspection time, and acquiring gravitational acceleration information, acceleration information and course information; verifying a vector of the forward direction, a vector of the vertical direction and a vector of a direction perpendicular to the direction of a car body, and creating a detecting coordinate axis; setting a unit detection time, a cycle detection time, and a sampling frequency and a detection trigger value of an acceleration sensor; averagely cutting data in the unit detection time into multiple parts of basic data; acquiring data of each sample point in each part of basic data, and acquiring an average value of the sample point data; acquiring a maximum basic datum in basic data in the unit detection time; setting an acceleration threshold duration threshold, a speed change threshold and a reaction time threshold; judging and feeding back the types of dangerous events. Through the way, the GPS-based dangerous driving detection system disclosed by the invention can detect and report the dangerous events in the process of driving accurately and timely, and therefore, the driving is safe and convenient.

Description

technical field [0001] The invention relates to the field of vehicle networking and dangerous driving detection, in particular to a GPS-based dangerous driving detection system. Background technique [0002] With the explosive growth of passenger cars and younger drivers, there are more and more car accidents caused by dangerous driving. The insurance industry also urgently needs technical means to reflect the driving habits of drivers to determine their insurance amount. The current method of detecting dangerous driving is to detect dangerous driving based on the on-board automatic diagnostic system (hereinafter referred to as OBD) and the on-board bus system to read speed, accelerator pedal position, brake pedal position, and steering. [0003] It has the following defects and deficiencies: 1, it needs extra connecting wires and peripheral equipment. Because it needs to be connected to the vehicle's bus system, it must support KWP2000, LIN, or CAN bus controllers. 2. Br...
