Vehicle dangerous driving alarm method and system

Abstract

The invention provides a vehicle dangerous driving alarm method and system. The vehicle dangerous driving alarm method comprises the steps that S1, an acquisition unit collects vehicle ignition and revolution speed signals, signals sent by hall sensors mounted on vehicle rear wheels, vehicle brake signals, and vehicle parking signals in real time after the vehicle is electrified to send to a processing unit; S2, the vehicle engine revolution speed condition, the vehicle speed condition, the driving braking condition and the parking braking condition are respectively determined; and S3, the running state of the vehicle is judged, and a corresponding alarm control signal is sent to an alarm unit. According to the vehicle dangerous driving alarm method, the vehicle ignition and revolution speed signals, the signals sent by the hall sensors mounted on vehicle rear wheels, the vehicle brake signals, and the vehicle parking signals can be collected and sent to the processing unit, the running state of the vehicle is accurately obtained by judging the vehicle engine revolution speed condition, the vehicle speed condition, the driving braking condition and the parking braking condition, and the vehicle dangerous driving alarm method is convenient to operate and can sensitively alarm dangerous operation of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle running state monitoring, in particular to a method and system for warning a dangerous driving of a vehicle. Background technique [0002] During the driving process of the vehicle, if the vehicle oversteers or the speed is too fast, it is easy to cause a rollover accident, especially for vehicles with a high center of gravity such as off-road vehicles and double-decker buses, the risk of rollover is greater. At present, multiple gravity sensors are installed under the seat cushion in the vehicle, and the rollover moment of the vehicle is obtained by sensing the mechanical gravity during the driving process of the vehicle, thereby realizing an early warning method for dangerous driving of the vehicle. However, the operation of installing the gravity sensor in this method is complicated and the sensitivity is poor. In the process of producing or assembling the gravity sensor, any failure of the gra...

Problems solved by technology

However, the operation of installing the gravity sensor in this method is complicated and the sensitivity is poor. In the process of producing or assembling the gravity sensor, if any gravity sensor fails, it will cause the performance of the entire pre-alarm system to fail, and its stability is poor.
