Although it should be noted that, hereinafter only with speed, rotating speed, the design parameter such as turn to illustrate
The content of initial data, in the context of the present invention, initial data can include but not
It is limited to specific example presented herein, but those skilled in the art can be according to concrete application
The requirement of environment, adjusts the detailed description of the invention of the present invention to be obtained about the state of vehicle
Other kinds of initial data.
In an embodiment of the invention, different types of event can be respectively directed to perform
Different process.Specifically, event i can represent different types of event, for example, it is possible to
Represent anxious accelerated events with i=1, anxious deceleration event can be represented with i=2, can represent with i=3
Racing, to event, can represent idle event with i=4.Those skilled in the art it should be noted that,
Various event given above is only the example of event, in concrete applied environment, and this area
Technical staff can also define other event types.
In an embodiment of the invention, initial data includes the speed of vehicle, and event i is
Anxious accelerated events, and from initial data, determine the event number of event i occurring at vehicle k
According toIncluding: the acceleration of vehicle is calculated based on speed；And in response to determination acceleration symbol
Close first threshold condition, determine
Owing to the speed of vehicle can be monitored in real time, thus can be according at different time points prison
Depending on to speed obtain acceleration.Assume at time pointWithThe speed obtaining is respectively
WithThen at time pointAccelerationBy judging this acceleration
(for example, acceleration is more than 2m/s whether to meet first threshold condition2), determine whether
Show anxious accelerated events.
In this embodiment, acceleration is worked asMore than 2m/s2When, then it is assumed that occur in that anxious acceleration
Event, now determinesOccur in that anxious accelerated events with instruction；Otherwise it is assumed that do not occur
Anxious accelerated events, now determinesWith instruction, anxious accelerated events does not occur.
In an embodiment of the invention, initial data includes the speed of vehicle, and event i is
Anxious deceleration event, and from initial data, determine the event number of event i occurring at vehicle k
According toIncluding: the acceleration of vehicle is calculated based on speed；And in response to determination acceleration symbol
Close Second Threshold condition, determine
It is similar to the description above for anxious accelerated events, owing to vehicle can be monitored in real time
Speed, thus acceleration can be obtained according to the speed monitoring in different time points.Assume
At time pointWithThe speed obtaining is respectivelyWithThe then acceleration at time pointBy judging this accelerationWhether meet Second Threshold condition (example
As acceleration is less than-2m/s2), determine whether anxious deceleration event.
In this embodiment, acceleration is worked asIt is less than-2m/s2When, then it is assumed that occur in that anxious subtracting
Speed event, now determinesOccur in that anxious deceleration event with instruction；Otherwise it is assumed that do not go out
Now anxious deceleration event, now determinesWith instruction, anxious deceleration event does not occur.
In an embodiment of the invention, initial data includes the speed of vehicle and turns to letter
Breath, event i is racing to event, and determines the thing of appearance vehicle k at from initial data
The event data of part iIncluding: the steering rate of vehicle is calculated based on speed and direction information；
And exceed predetermined threshold in response to steering rate, determine
Owing to can obtain in real time at the velocity information of each time point and direction information, thus
Speed when can turn to based on vehicle judge vehicle whether just racing to.For example,
Assume at time pointThe speed obtaining isWhenHigher than predetermined threshold (for example, 40 kilometers
/ hour) when, then it is assumed that vehicle just at racing to now may determine thatTo indicate appearance
Racing is to event；Otherwise it is assumed that vehicle does not has racing to now may determine thatWith instruction
Racing does not occur to event.
The steering angle that those skilled in the art are also based on steering wheel in direction information sets
Put different threshold condition for judge whether to occur racing to.For example, it is assumed that with 0.1 second
Time interval monitors speed and direction information, when the steering angle finding steering wheel is 90 degree,
It is believed that the speed of less than 40 kilometers/hour is safe, now can will determine that threshold value sets
Put at 40 kilometers/hour.Again for example, when the steering angle finding steering wheel is 180 degree,
It is believed that the speed of less than 20 kilometers/hour is safe, now can will determine that threshold value sets
Put at 20 kilometers/hour.
In other words, the steering angle of steering wheel is bigger, then safe speed associated therewith is lower；
The steering angle of steering wheel is less, then safe speed associated therewith is higher.Art technology
Personnel can arrange no judgement threshold based on above-mentioned principle for different steering angles
Value, in order to more accurately determine vehicle whether occur in that racing to.
In an embodiment of the invention, based on event dataGenerate the state of vehicle k
ParameterIncluding: based on below equation calculating state parameter:Wherein xiIt is
Event data for event iDynamic gene.
It should be noted that, due to vehicle it is possible that various event (for example, is suddenly accelerated, suddenly subtracted
Speed, racing to etc.), thus each event pair in various types of event can be added up one by one
Impact in the transport condition of vehicle.And owing to different types of event is for the traveling of vehicle
The impact of state is different (for example, in terms of the security of vehicle etc.), thus can be right
Different types of event arranges different Dynamic gene xi, in order to more accurately evaluate vehicle
Transport condition.
Will be described in now how calculating state parameter, for example, it is assumed that represent vehicle with i=1
Anxious accelerated events occurs, and in the time period being monitoredExtremelyPeriod, altogether discovery 3 times
Anxious accelerated events, and for the Dynamic gene x of anxious accelerated eventsi=1, then now whole 3
Anxious accelerated events for the contribution of state parameter is:
Again for example, it is assumed that represent that vehicle racing occurs to event with i=3, and monitored
Time periodExtremelyPeriod, discovery 2 priorities turn to event altogether, and for racing to event
Dynamic gene xi=2, then now whole 2 racings to event for the contribution of state parameter are:
In the context of the present invention, the impact of various types of event can also be considered.
Continue example above, it is assumed that in the time period being monitoredExtremelyPeriod, altogether discovery 2 times
Racing is to event, and 3 priority accelerated events, then now whole 5 events are for state parameter
Impact is:
Wherein n represented in the time period being monitoredExtremelyThe number of the type of the event of period discovery
Amount.For example, the n=1 when only finding anxious accelerated events, and anxious acceleration and racing ought be found simultaneously
To when then n=2.
In an embodiment of the invention, initial data includes speed and the rotating speed of vehicle,
Event i is idle event, and from initial data, determine event i of appearance at vehicle k
Event dataIncluding: in response to speed, less than predetermined speed, rotating speed is non-zero, determines
In embodiments of the present invention, idle event refers to that speed is very slow or stops and starting
The situation of machine rotating speed non-zero.Driver and passenger can be affected due to idle event to a great extent
Experience by bus, and also the performance of vehicle can be significantly affected, so that consider idle event.
In the context of the present invention, those skilled in the art self-defined can judge whether idling occur
The judgment threshold of event, for example, it is possible to definition is less than 5 kilometers/hour and engine when speed
Idle event occurs when rotating speed is not zero.
Urgency mentioned above accelerates, anxious slow down and when racing generally only occurs in shorter to event
In the range of between (for example, several seconds), but idle event would generally continue longer time (example
As, in the case that running at a low speed of causing because of congestion in road or original place wait, idle event
May last for several minutes even longer time).Therefore, it is possible to for idle event occurs
Time period and the whole time period between ratio, evaluate the traveling for vehicle for the idle event
The impact of situation.
In an embodiment of the invention, based on event dataGenerate the state of vehicle k
ParameterIncluding: based on below equation calculating state parameter:
Wherein Δ t is in the time periodExtremelyThere is the time span of idle event, and x in periodiIt is pin
Event data to idle eventDynamic gene.
Assume needs assessment vehicle k in the time periodExtremelyPeriod is (for example,Point
Clock) transport condition, and occurred in that idle event (i.e., at the 3rd minute during the 8th minute
Δ t=8-3=5), and for the Dynamic gene x of idle eventi=0.5, then now idle event
Impact for state parameter is:
When in the time periodExtremelyWhen idle event occurs repeatedly in period, can also add up one by one every
The impact on state parameter for the individual idle event, will not be described in great detail in the context of the present invention.
Hereinafter will refer to Fig. 5 to be described in detail how to consider various types of event pair
Impact in state parameter.Fig. 5 diagrammatically illustrates the use according to one embodiment of the present invention

Shown in reference 520 at time t1The anxious accelerated events occurring, such as reference 522 institute
Show at time t2Occur anxious deceleration event, as shown in reference 524 at time t3sExtremely
t3ePeriod occur idle event, and as shown in reference 526 at time t4Occur
Racing is to event.
In the example depicted in fig. 5,4 events all can produce impact to the state parameter of vehicle.
Assume the Dynamic gene x for anxious accelerated events1=1, for the Dynamic gene of anxious deceleration event
x2=1, for the Dynamic gene x of idle event3=0.5, for racing to the Dynamic gene of event
x4=2, andt3e-t3s=3, then now whole 4 events are for state parameter
Impact is:
In an embodiment of the invention, farther include based in following is at least arbitrary
Item adjusts state parameter: the original state parameter of vehicle, traveling during the time period for the vehicle
Distance and the size of time period
Specifically, the state parameter of vehicle can also be by the original state parameter of vehicle, vehicle
The impact of the size of the operating range within the time period to be assessed and time period, thus can enter
One step adjusts state parameter based on above-mentioned information.In addition, at event type given above
In example, anxious accelerate, anxious slow down, racing is to being all detrimental to driver and passenger with idle event
