Description
Technical field
The present invention relates to vehicle safety travel technical field, more particularly to a kind of ADAS product deviation report
Alert system.
Background technique
Currently, counting according to Ministry of Communications, the motor traffic accidents there are about 50% is because automobile deviates normal traveling lane
Caused, studying carefully its main cause is mainly driver's irritability, absent minded or driving fatigue.23% car steering
It at least falls asleep on the steering wheel in member one month primary;66% trucker oneself dozes off in driving procedure;28%
Trucker have on the steering wheel sleeping experience in one month, so surprising ratio, which suffices to show that, prevents lane inclined
From significance.
But the deviation of existing driving assistance system (ADAS) product alarm be audible alarm strategy be directly with
The output of alert event is related, is essentially all that the time cross-section chosen in certain vehicle operation is judged, instead
The variation tendency near this case point is not answered, while being researched and developed on the basis of view-based access control model (camera) mode acquires data,
In rain and snow or when the not high road surface of visibility, the accuracy for acquiring Lane Mark can decline for they.
Therefore, how to prejudge vehicle in the period to deviate situation and alarm, and accurate acquisition in the presence of a harsh environment
The problem of road surface lane situation is those skilled in the art's urgent need to resolve.
Summary of the invention

In order to further optimize the above technical scheme, deviation computing module calculating process:
Obtaining nearest lane line and nearest wheel distance d, vehicle current vehicle speed according to information acquisition module is V running car
The angle theta in direction and nearest lane line, entrance angle θ and deviation time TTLC consecutive variations carry out, then TTLC=d/Vsin
θ;
Safety, which is set aside some time, is spaced t0, presetting TTLC threshold value t1, the starting vehicle velocity V of early warning0, preset nearest lane away from
Nearest wheel safe distance d0;Entrance angle θ when intentional rapidly lane change or steering0, θ0Greater than 15 °;When the vehicle in traveling has vehicle
When road deviates tendency, i.e. TTLC > t1, and TTLC < t0, while vehicle velocity V > V0, entrance angle θ < θ0When, then it is linear to pass through lane in advance
State, voice guard export a low frequency alarm sound, and vibration of steering wheel device is opened, and HUD head up display shows that vehicle deviates
Information;
When vehicle traveling direction is begun to deviate from, θ >=θ0, and TTLC < t1, and t1<t0, while away from lane line distance d to t
Derivative (d (d)/dt) < 0 when, i.e. distance d be gradually successively decrease, then vehicle becomes closer to deviate the lane line passed through,
To pass through lane line state, voice guard exports high-frequency alarm sound, and vibration of steering wheel device is opened, and HUD head up display is aobvious
Show that vehicle runout information, alarm sound are synchronous with the decision content of (d (d)/dt) < 0 with duration of shaking;
As TTLC < t1, and t1<t0, while when away from lane line distance d to derivative (d (d)/dt) > 0 of t, i.e. distance d be by
Cumulative to add, then vehicle will be more and more far away from that will deviate the lane line passed through, not pass through lane line state, high-frequency alarm sound solution
It removes, vibration of steering wheel device is closed, and HUD head up display shows that vehicle runout information terminates;
As d < d0When, then to have passed through lane line state, this time deviation terminates, and low frequency alarm sound terminates, direction
Disk vibrator is closed, and HUD head up display shows that vehicle runout information terminates.
In order to further optimize the above technical scheme, host computer real-time monitoring vehicle lane deviates situation, may be implemented remote
Range monitoring, real time inspection vehicle driving situation, can be applied to traffic department's task of supervision, can quick obtaining danger traveling vehicle
Information.
Embodiment 1
When due to inadvertent or misoperation, vehicle longitudinal axis and lane line being caused to produce in vehicle straight trip driving process
Raw angle theta is less than θ0When, current TTLC can be calculated by current instantaneous speed V, distance d and angle theta, TTLC and peace at this time
It sets aside some time entirely and is spaced t0Judged, sets aside some time be spaced t safely0It is whether prediction vehicle occurs to deviate and the preset time
Value, presetting TTLC threshold value t1It is further to judge that vehicle has occurred and that lane line deviates preset time value, by above-mentioned
The calculation formula of TTLC can obtain, and when speed V, distance d or bigger angle theta any amount, all may cause vehicle shorter
Deviate in time and pass through lane line, therefore by time TTLC and preset t0、t1It is compared, can consider driving conditions comprehensively,
And alarm, to prevent causing danger, when speed V, distance d are identical, the angle theta more big then time is shorter, therefore t0﹥ t1Pacify when being less than
It is judged as there is deviation tendency when setting aside some time entirely, as passes through lane line state in advance.
Embodiment 2
When vehicle enters turn condition by straight trip, and lane line is straight trip direction parallel lines, at this time θ >=θ0, according to
Information acquisition module available current instantaneous speed V, distance d, are thus calculated TTLC, with t1It is compared, if
TTLC<t1, and as (d (d)/dt) < 0, i.e. distance d is gradually to successively decrease, then vehicle becomes closer to linear with the vehicle longitudinal axis
At angle and apart from the closer lane line of vehicle, if such situation vehicle heading is constant, vehicle can be passed through eventually in vehicle
Diatom, therefore be judged as and pass through lane line state.And when working as (d (d)/dt) ﹥ 0, i.e. distance d is to gradually increase, then vehicle is more next
Further away from the lane line passed through will be deviateed, it is possible to which vehicle has carried out driving direction amendment, to enable distance d increase, then
Vehicle will not pass through lane line;Or lane line is curved, although vehicle is in turn condition, vehicle longitudinal axis with
Lane line angle changes, while distance d is increased, and vehicle will not pass through lane line, therefore be then judged as and do not pass through lane
Linear state.
Embodiment 3
A safe distance value d of the predetermined wheel apart from nearest lane line0, as distance d ﹤ d0When, then vehicle may be at this time
Lane line will be rolled, or has rolled lane line, can not make automotive run-off-road line by correcting direction of traffic,
It passes through lane line and has become certainty, therefore be judged as that vehicle has passed through lane line.
This application provides a kind of ADAS product driveway deviation alarming system, realizes vehicle in the anticipation period and deviate feelings
Condition is simultaneously alarmed, and can carry out the alarm of diversified forms, while showing current deviation situation using HUD head up display
Be adjusted convenient for driver, and can accurately be obtained by infrared sensor in the presence of a harsh environment road surface lane situation into
And carry out deviation calculate the application can accurately carry out in the period deviation alarm, improve travel safety,
Traffic accident odds is effectively reduced.
