Brief description of the drawings
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the process flow diagram of the method for the judgement vehicle driving condition that provides of the embodiment of the present invention;
Fig. 2 is the structural representation of the system of the judgement vehicle driving condition that provides of the embodiment of the present invention.
Embodiment
Understand for technical characterictic of the present invention, object and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
In the method for the judgement vehicle driving condition that preferred embodiment of the present invention provides, this automobile comprises pick-up unit, this pick-up unit can for example, be integrated with existing automobile electronic system (central processing unit or vehicle condition information collecting device), for the car steering behavioural information of real-time analysis automobile bus, judge that whether automobile braking force, throttle dynamics and acceleration be reasonable, i.e. whether dangerous driving, as dangerous driving, will immediately report Surveillance center, Surveillance center can carry out voice reminder to driver.
The method of the judgement vehicle driving condition that as shown in Figure 1, preferred embodiment of the present invention provides comprises the following steps:
Step S1: the car steering behavioural information in Real-time Collection automobile bus, described driving behavior packets of information oil scraper door dynamics, braking strength, acceleration and temporal information; Concrete is in real time the car steering behavior in automobile bus to be gathered by the vehicle condition information collecting device in automobile electronic system (as throttle pressure pick-up unit, skid resistance pick-up unit, velograph etc.).Automobile bus has very high internet security, communication reliability and real-time, and simple and practical, and network cost is low; Even in basement or tunnel, even if the various driving behavior information of automobile can be detected, and in automobile bus, data are all timely and accurate, and and vehicle synchronous.Wherein, automobile bus can be Controller Area Network(CAN) bus, Local Interconnect Network(LIN) bus or Vehicle Area Network(VAN) any one in bus.
Step S2: judge whether dangerous driving behavior according to car steering behavioural information, if so, carry out S3, if not, return to S1; In the present embodiment, utilize the central processing unit on automobile to judge whether dangerous driving to driving behavior.Described dangerous driving behavior generally comprises anxious acceleration and anxious deceleration, and its concrete criterion is as follows:
In present embodiment, judge whether to exist the anxious method of accelerating to be: whether the acceleration that judges automobile is greater than a first predetermined acceleration, throttle dynamics reaches a predetermined throttle range simultaneously, if above-mentioned two conditions meet simultaneously, judge that automobile suddenly accelerates, otherwise judge that automobile does not suddenly accelerate.Specifically in the present embodiment, the first acceleration is set to 5.5m/s
2, this throttle range is set to 90% of total range.Suddenly suddenly accelerate not only driver itself in danger, but also can cause danger near the automobile normally travelling it, cause traffic hazard.
In present embodiment, judge whether to exist anxious method of slowing down to be: whether the acceleration that judges automobile is greater than a second predetermined acceleration, braking strength reaches a predetermined brake range simultaneously, if above-mentioned two conditions meet simultaneously, judge that automobile suddenly slows down, otherwise judge that automobile does not suddenly slow down.Specifically in the present embodiment, be set to-7m/s of the second acceleration
2, this brake range is set to 90%.If automobile is in the process of moving, suddenly anxious deceleration, and do not send in advance any signal, the automobile travelling after him just has and probably knocks, and traffic hazard occurs.
Step S3: above-mentioned dangerous driving behavioural information is sent to Surveillance center.In the present embodiment, can carry out wireless transmission to dangerous driving behavioural information by existing automobile monitoring network or cordless communication network.
Step S4: the Surveillance center position that positioning system is searched the automobile of dangerous driving behavior in time via satellite, and the positional information of the automobile of this dangerous driving behavioural information and dangerous driving behavior is stored in the database of Surveillance center; In other embodiments, can also adopt other locator meamss to position automobile, locator meams as existing in base station, wifi etc.By the dangerous driving behavioural information of the automobile of dangerous driving behavior and positional information are stored in the database of Surveillance center, that automobile is monitored on the one hand, on the other hand, in the time there is traffic hazard, can be according to the data in the database of Surveillance center, for the fix duty of traffic hazard provides legal basis.
Step S5: the driver who reminds dangerous driving.In present embodiment, the central processing unit of automobile itself can be reminded immediately the driver of this car in the time judging current dangerous driving behavior in modes such as voice.In addition, Surveillance center is receiving after dangerous driving behavioural information, also can utilize existing wireless communication means to issue voice reminder to this automobile, warns this driver's safe driving.
In the time reminding driver, can adopt the form of voice and/or picture to remind driver your current state time in dangerous driving, this prompting can be same assisting automobile driver, also can remind according to judged result, for example: same voice reminder is that " you are current in dangerous driving; please note safety " reminds driver, also can be according to different judged results, remind driver by voice message " you are current in anxious acceleration mode; please note safety " or " you are current in anxious deceleration regime, please note safety " etc.
The method of the judgement vehicle driving condition of another embodiment of the present invention is further comprising the steps:
Step S6: utilize Surveillance center to remind the driver within a certain distance with the garage of dangerous driving.When automobile accelerates or when anxious deceleration regime in anxious, concerning with in anxious accelerate or the automobile of the anxious garage slowing down within a certain distance, also will cause great danger, Gu position can be searched by Surveillance center, to with accelerate or the automobile of the anxious garage slowing down within a certain distance carries out voice reminder in anxious, make the driver in certain distance with interval carry out early counter-measure, reduce the generation of traffic hazard.
As shown in Figure 2, be the preferred embodiment of the system of judgement vehicle driving condition provided by the invention.
A kind of system that judges vehicle driving condition, comprise a pick-up unit, this pick-up unit can for example, be integrated with existing automobile electronic system (central processing unit or vehicle condition information collecting device), for the car steering behavioural information of real-time analysis automobile bus, judge that whether automobile braking force, throttle dynamics and acceleration be reasonable, i.e. whether dangerous driving, as dangerous driving, will immediately report Surveillance center, Surveillance center can carry out voice reminder to driver.
