A driving level assessment method for bus drivers based on mems IMU

Abstract

The invention discloses a method for evaluating the driving level of bus drivers based on MEMS IMU. The three-axis MEMS gyroscope, three-axis MEMS accelerometer, three-axis geomagnetic sensor, GPS, and temperature sensor respectively collect data to obtain the bus status information and transmit it to the DSP processor. The DSP processor determines whether each information in the received bus state information exceeds the corresponding threshold, and the information exceeding the threshold is recorded as improper operation data; according to the received bus state information, the acceleration rate of change is calculated, and the acceleration is calculated. The change rate information is added to the bus status information; the bus status information and improper operation data are stored in the data storage SD card. After the bus runs, the computer reads the information in the data storage SD card and evaluates the driving level of the bus driver. The invention collects the running data of the bus in real time, gives an alarm in real time, and improves the running safety of the bus.

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
