Description
Technical field
The utility model relates to a kind of driving behavior analysis car-mounted terminal, following referred to as terminal, it is characterized in that to be fixed on vehicle with arbitrarily angled installation directly or indirectly, and driving behavior analysis function can be realized, be applied to car steering behavioral analysis technology and automatic Pilot control technology field.
Background technology
The technical scheme great majority of current car steering behavioural analysis adopt to detect based on the sensor such as acceleration transducer, gyroscope, the real-time dynamic data exported by MCU processor pick-up transducers, and calculate driving behavior data.But the defect of this technical scheme to identify direction of traffic, if know direction of traffic, must the setting angle of limiting terminal sensor, such as terminal the some axles installing fixing brief acceleration sensor must point to straight the forward direction of vehicle, acceleration transducer certain two axle must and plane-parallel.
Summary of the invention
The utility model relates to a kind of driving behavior analysis car-mounted terminal, terminal can be fixed on vehicle with arbitrarily angled installation directly or indirectly, and direction of traffic can be identified and realize driving behavior analysis function, described direction of traffic is working direction, direction of retreat, left direction, the right direction of vehicle, and described driving behavior comprises anxious acceleration, anxious deceleration, zig zag, sudden turn of events road, collision, rollover, shakes, falls, dynamic acceleration data in towing, vehicle body level inclination, raw acceleration data, direction of traffic.
Terminal is primarily of sensor group, MCU processor two parts composition, the data that MCU processor Real-time Collection and processes sensor group export, described sensor group is acceleration transducer or acceleration transducer and gyrostatic combination, and wherein acceleration transducer is two axle acceleration sensors or 3-axis acceleration sensor.
Terminal needs to carry out attitude correction when installing and be fixed on vehicle first, is namely calculated the attitude parameter of terminal by MCU processor, and attitude parameter is for identifying direction of traffic and calculating driving behavior analysis data.
The driving behavior analysis data that terminal is calculated can carry out secondary application as required, described secondary application comprises Driving control and adjustment, word or picture show, voice message, buzzing prompting, stored record, remote transmission, statistical study.
Accompanying drawing explanation
Accompanying drawing 1 is the hardware system composition diagram of driving behavior analysis car-mounted terminal.
Embodiment
Principle of work of the present utility model and workflow is described in detail: terminal is made up of sensor group, MCU processor two parts below in conjunction with accompanying drawing, see accompanying drawing 1, data that MCU processor is exported by serial interface bus (as I2C bus, spi bus etc.) Real-time Collection sensor group and analyzing and processing is carried out to data, and computational analysis driving behavior data.
Because terminal is fixed on vehicle with arbitrarily angled installation, so need first to carry out an attitude correction, the object of attitude correction is the initial attitude making terminal establish self, calculate the attitude parameter of terminal, attitude parameter is for identifying direction of traffic and calculating driving behavior analysis data, and the attitude parameter only having calculated terminal is just by software identification direction of traffic with calculate driving behavior analysis data.
Attitude correction process comprises following two steps: the data that (1) terminal MCU processor Acquire and process sensor group exports, and goes out terminal vertical direction attitude parameter according to mechanics principle, trigonometric function formulae discovery; (2) the vertical direction attitude parameter drawn according to step (1) and the cosine law calculate end level direction attitude parameter.
Through above attitude correction step, terminal establishes the relation between acceleration transducer axis of orientation and direction of traffic, and this relation is represented by the vertical direction attitude parameter of terminal and horizontal direction attitude parameter.
Terminal just can normally work after attitude correction, terminal when normally working, data that MCU processor Real-time Collection and processes sensor group export, and calculate driving behavior analysis data according to the attitude parameter of terminal.
The driving behavior analysis data that terminal calculates can carry out secondary application as required, secondary application comprises Driving control and adjustment, word or picture show, voice message, buzzing prompting, stored record, remote transmission, statistical study function.As realized word or picture display function then terminal increase display screen, Word message or picture are sent on display screen by MCU processor; As realized buzzing prompt facility then terminal increase hummer, piping of MCU processing controls hummer; As realized remote transmission and function of statistic analysis then terminal increase radio communication module and service device end, driving behavior analysis data are sent to radio communication module by MCU, and radio communication module is sent to server end data again and carries out statistical study.
