Description
Technical field
The invention belongs to technical field of vehicle, and in particular to a kind of driving habit analysis system and its analysis method.
Background technique
As the improvement of people's living standards, vehicle is almost the essential vehicles of every household, with this vehicle
Increase, the traffic accident as caused by the bad steering habit of driver is also increasing, vehicle currently on the market
It is usually individually to show current vehicle speed and running time on display, this display mode cannot intuitively reflect driver
Driving habit and driving condition, if things go on like this, driver is easy to form bad steering habit without knowing, therefore proposes one
Kind driving habit analysis system and its analysis method.
Summary of the invention
The present invention is directed to the situation of the prior art, provides a kind of driving habit analysis system and its analysis method.
The present invention use following technical scheme, a kind of driving habit analysis system, including
Module is obtained, for obtaining speed and time from vehicle bus when speed often changes and being transferred to screening mould
Block；
Screening module received the speed of acquisition and the time and determines effective speed, if the duration of the speed obtained
The speed is then abandoned less than 1s, if the duration of the speed obtained is more than or equal to 1s, it is determined that for effective speed and should
Effective speed and time tranfer are to judgment module；
Judgment module judges driving condition for effective speed and time based on the received and is transferred to judging result aobvious
Show module, the driving condition includes accelerating too quickly, brake too quickly, the fast traveling of tortoise and happy traveling；
Display module, for counting the number of the same day each driving condition and showing statistical result.
As a further improvement of the above technical scheme, the judgment module includes that first judging unit and secondary judgement are single
Member, in which:
The first judging unit is used to judge driving condition for the first time according to the duration of effective speed and will
First judging result is conveyed to the secondary judging unit of secondary judging unit, if the duration of effective speed arrives in 1s

Speed duration between 1s to 10s, then be judged as accelerate it is too quickly or brake it is too quickly, if effective speed it is lasting when
Between in 10s or more, then be judged as tortoise speed traveling or happy traveling；
Step S3.2: carrying out secondary judgement according to the first judging result of step S3.1, if first judging result is to add
Speed is too quickly or brake is too quickly, then according to formula
Acceleration=(3600*1000* (commencing speed-end speed))/duration (wherein acceleration in the formula
Unit is Km/s2, commencing speed and the unit for terminating speed are Km/s, and the unit of duration is s)
The acceleration driven at this time is calculated, is judged as that acceleration is too quickly if acceleration is positive number, if acceleration is
Negative and acceleration are less than -460Km/s2, then it is judged as that brake is too quickly；
If the result judged for the first time travels as tortoise speed or happy traveling, further judged according to effective speed,
If effective speed is greater than 20Km/h, judge to drive at this time to travel freely, if effectively speed is sentenced 0 to 20Km/h
Disconnected drive at this time is that tortoise speed travels.
As a further improvement of the above technical scheme, further include step S3.3 after the step S3.2:
Step S3.3: too quickly driving condition is accelerated further to be judged to being judged as, if acceleration is greater than
270Km/s2And commencing speed and end speed are respectively less than 20Km/h, then it is too quickly to be judged as that starting accelerates, if acceleration is greater than
