Bus driver driving level assessment method based on MEMS IMU

Abstract

The invention discloses a bus driver driving level assessment method based on an MEMS IMU. According to the method, a three-axis MEMS gyroscope, a three-axis MEMS accelerometer, a three-axis geomagnetic sensor, a GPS and a temperature sensor respectively collect data to obtain state information of a bus, and the state information is sent to a DSP processor; the DSP processor judges whether each piece of the received state information of the bus exceeds a corresponding threshold value or not, and the information exceeding the threshold value is recorded as improper operation data; the change rate of acceleration is calculated according to the received state information of the bus, and the change rate information of the acceleration is added into the state information of the bus; the state information of the bus and the improper operation data are stored in a data storage SD card. After bus driving is finished, a computer reads the information stored in the data storage SD card and assesses the driving level of a bus driver. Travelling data of the bus are collected in real time, an alarm is given in real time, and therefore travelling safety of the bus is improved.

Description

technical field [0001] The invention relates to a driving level evaluation method of a bus driver, in particular to a MEMS IMU-based bus driver driving level evaluation system and evaluation method. Background technique [0002] As the most common means of public transport, buses have greatly promoted the development of urbanization. At the same time, in order to deal with environmental pollution, the government encourages and advocates public transportation. The bus is the main artery of the city, which brings great convenience to the citizens every day. The bus generally carries a relatively large passenger capacity, which makes the driving level of the driver particularly high. In my country, bus accidents occur from time to time, so it is very important to evaluate the driving level of bus drivers on a regular basis. The present invention designs a system for evaluating the driving level of bus drivers, which can grade the driving level of bus drivers , so as to select ...

AI Technical Summary

Problems solved by technology

[0003] The driving process of the bus needs to start and stop repeatedly, so the driving stability of the driver directly affects the comfort of the passengers. At present, the bus drivers in many cities have random merging, excessive acceleration at the start, emergency braking, emergency braking, etc. Turning, etc., such driving behavior will cause discomfort to passengers, and even cause collision and fall injuries to the elderly and children in the bus; Being thrown in the other direction can easily injure the passengers, and what's more, there will be a rollover accident of the car body
