Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Referring to Fig. 1, be the flow chart of steps of a kind of driving training recording of information embodiment of the method one of the embodiment of the invention, the method for present embodiment comprises:
Step S101: obtain the physical state parameter information of the training vehicle of student's driving, described physical state parameter information comprises the acceleration value of described training vehicle;
When the student of driver training mechanism need to be in this driver training organization studies vehicle drive technology, be equipped with an IC-card for each student for a moment, this IC-card is used for the identification of student's identity, the student registers by the brush IC-card, and this student registered the time, and the information recording /s such as student training curriculum information and student's class hour are on this IC-card.
Wherein, the class hour that in the driving training information that IC-card records, can comprise the student, be the training information such as time of steering vehicle and distance travelled, in order so that the accuracy of the information such as student's class hour that record on the IC-card, just to judge accurately whether train vehicle is in transport condition.Therefore, need to obtain the physical state parameter of the training vehicle of student's driving after the student brushes IC-card, this physical state parameter comprises, the acceleration value of training vehicle.Certainly, the physical state parameter can also comprise the orientation angles information of training vehicle, the information such as speed of vehicle.
The mode of obtaining the training vehicle acceleration can have multiple, and acceleration value that can Real-time Obtaining training vehicle also can be sampled to the physical state parameter information of described training vehicle according to the time interval of setting.Obtain the acceleration value of once training vehicle by sampling at regular intervals, such as the acceleration value every 5ms once sampling training vehicle.The physical state information of the training vehicle that gets access to is also preserved, and whether vehicle is in transport condition so that the physical state information that follow-up foundation gets access to is judged training.
Step S102: calculate the changing value of the acceleration value that gets access in the schedule time, judge whether the changing value of described acceleration value surpasses default numerical range, if so, think that then described training vehicle is in transport condition;
After the acceleration value that gets access to the training vehicle, need to process in order to judge this training vehicle whether be in transport condition to the numerical value of acceleration, can calculate the changing value of the acceleration value that gets access in the schedule time, whether judge vehicle above default numerical range by the changing value of acceleration value and whether be in transport condition.
The mode of calculating the changing value of acceleration value in the schedule time has multiple, can for: 1 to 2N the acceleration value that gets access to successively in the schedule time is divided into groups, calculate respectively 1 mean value to the mean value of N acceleration value and N+1 to 2N acceleration value, with the difference of two mean values the calculating changing value as acceleration value, wherein, N is more than or equal to 1.For example, get access to successively 10 acceleration value in the schedule time 20ms, can calculate the mean value of 10 acceleration value that get access in the front 10ms, and the mean value of 5 acceleration value in the rear 10ms of calculating, the mean value of these two the calculating number of degrees values that calculate subtracted each other obtain a difference, judge whether this difference exceeds the numerical range of setting, and then judge vehicle and whether be in transport condition.
Further, when N equals 1, can be with the difference of the acceleration value that gets access to for adjacent twice as judging Vehicle Driving Cycle whether foundation.In other words, when according to the time interval of setting the physical state parameter information of described training vehicle being sampled, can also calculate the difference of the acceleration value that the neighbouring sample point collects, with the difference of the described acceleration value changing value as acceleration value, and then judge whether the difference of the acceleration value that calculates exceeds default numerical range.
Certainly can also average to the acceleration sampled value that gets access to of repeatedly sampling in the schedule time, with the mean value of the acceleration value in this Preset Time that calculates as the acceleration value in this Preset Time, if this acceleration value does not have to surpass default numerical range with the difference of the acceleration value that calculates before, think that then this training vehicle is not in transport condition; Opposite, if the difference of acceleration value surpasses default numerical range, think that then the training vehicle is in transport condition.For example, acceleration value every 5ms once sampling training vehicle, and the Preset Time that arranges is 20ms, then can sample acceleration value four times at this Preset Time, calculate the mean value of the acceleration value that samples in this 20ms, and the mean value that will calculate the acceleration value in the 20ms of this schedule time is as the acceleration value in this Preset Time, if the difference of the acceleration value in this 20ms and the acceleration value in the upper Preset Time just can think that vehicle is not in transport condition in default numerical range.
Real-time sampling to acceleration value can not react really vehicle and whether be kept in motion, therefore can preset time span, and according to the acceleration value of the training vehicle that gets access in the setting-up time length, calculate in the given time the average acceleration numerical value (or claim acceleration value mean value) of the training vehicle of each group and then respectively organized the difference of the mean value of acceleration value, so according to acceleration value difference judge whether vehicle is kept in motion.
Calculate the acceleration value that gets access in the schedule time changing value can also for, calculate the maximum disparity between the acceleration value that gets access in the schedule time, certainly, calculating in the schedule time mode of the changing value of acceleration value has much and does not enumerate one by one at this.
Step S103: when described training vehicle is in transport condition, record described student's driving training information.
When judging vehicle and be in transport condition, the operation of driving training information that just can the trigger recording student.Wherein comprise in this driving training information: the driving training car moves information, the start time of the training Vehicle Driving Cycle of driving such as the student, and the information such as Vehicle Driving Cycle time.That is to say, when the training vehicle of judging student's driving is in transport condition, the start time of travelling that just can record this training vehicle, and running time, thus the student training time that guarantees record is identical with the training time of student's reality.Other information such as training course that certainly, can also comprise the student in this driving training information.
Need to prove that the acceleration value of the training vehicle that gets access among the step S101 can have multiple, this acceleration value can be the acceleration value of orthogonal three change in coordinate axis direction.These orthogonal three coordinate axis can be thought the coordinate axis perpendicular to each other in the space, as, the space coordinates of commonly using in the mathematics, x, y, z coordinate axis.
In the given time, get access to the acceleration value of orthogonal three change in coordinate axis direction, calculate the changing value of the acceleration value that gets access in the schedule time, can be the acceleration value of three change in coordinate axis direction that statistics got access in the schedule time, calculate respectively the changing value of the acceleration value of each change in coordinate axis direction, and the changing value of acceleration value of judging respectively each change in coordinate axis direction is whether all above default numerical range.Concrete, can add up respectively 1 to 2N acceleration value that three coordinate axis got access to successively in the schedule time, calculate respectively the mean value of 1 to N acceleration value on each coordinate axis and the mean value of N+1 to 2N acceleration value, then calculate respectively the difference of the mean value of the mean value of 1 to N acceleration value on the three axes and N+1 to a 2N acceleration value, and whether the difference of judging respectively the mean value of acceleration value on three coordinate axis is all above default numerical range, if so, think that then vehicle is in transport condition.With the changing value of the mean value of the acceleration value of three orthogonal change in coordinate axis direction as Vehicle Driving Cycle whether foundation be because: when the training vehicle launch but when not travelling, this training vehicle may have certain vibration, so that being engraved in, the some time may produce certain acceleration fluctuation on the change in coordinate axis direction, but the acceleration fluctuation value of this change in coordinate axis direction remains in certain range of drift by repeatedly cancelling out each other after sampling and the calculating mean value in the certain hour section.
For example, obtain by sampling every 5ms and once to train the orthogonal x of vehicle, y, the acceleration value of three change in coordinate axis direction of z, and the acceleration value of the statistics schedule time (establishing Preset Time is 20ms) interior three change in coordinate axis direction, and calculate respectively the mean value of axial four acceleration value of x in the 20ms, the mean value of four acceleration value of y direction of principal axis, the mean value of four acceleration value of z direction of principal axis, respectively as the axial acceleration value of the x in this 20ms, the axial acceleration value of y, the axial acceleration value of z, then judge respectively the axial acceleration value of x in this 20ms, the axial acceleration value of y, the axial acceleration value of x that (in the upper schedule time) calculates in z direction of principal axis acceleration value and the upper 20ms, the axial acceleration value of y, whether the difference of z direction of principal axis acceleration value is all in preset range, if so, then this training vehicle is not kept in motion.Take the x axle as example, the axial acceleration value of the x that gets access in 20ms is respectively: 0.04m/s
2,-0.08m/s
2,-0.04m/s
2, 0.04m/s
2, then the mean value of the acceleration value of x direction is-0.04m/s in this 20ms
2If the mean value of the acceleration value of the x axle in the upper 20ms is 0.04m/s
2, then the difference of twice mean value is-0.08m/s
2If default numerical range is-0.12m/s
2～0.12m/s
2, then the difference of the acceleration value of x axle can be judged the training vehicle and not be in transport condition in preset range.The calculating of the acceleration value of two other coordinate axis is identical with calculating and the determination methods that the x direction of principal axis accelerates numerical value with judgment mode, but in actual applications, since have acceleration of gravity existence, when supposing that the z axle is vertical direction (direction of acceleration of gravity), when obtaining the axial acceleration value of z and calculate z direction of principal axis acceleration value mean value, need to consider the existence of acceleration of gravity, in computation process, need the numerical value that deducts acceleration of gravity with the axial acceleration value of z.
Get access in the given time the acceleration value of orthogonal three change in coordinate axis direction, calculate the changing value of the acceleration value that gets access in the schedule time, also can for: the acceleration value that at every turn gets access to three change in coordinate axis direction is calculated the vector acceleration numerical value of its three axes, and calculates the changing value of the vector acceleration numerical value of the three axes in the schedule time.
The acceleration value of obtaining also can for: obtain the training vehicle two axial acceleration value of mutual vertical coordinate, such as the acceleration value of two orthogonal change in coordinate axis direction on the surface level direction.Corresponding, calculate the changing value of the acceleration value that gets access in the schedule time, can be the changing value that calculates respectively the acceleration value of two change in coordinate axis direction that get access in the schedule time.Certainly other modes can also be arranged, not enumerate one by one at this.
When the foundation acceleration value judges whether the training vehicle is in transport condition, other physical state parameter informations that can also consider the training vehicle judge whether vehicle is in transport condition, therefore the physical state parameter information that gets access to can also comprise: the orientation angles information of training vehicle, as, the angles of this training vehicle and direct north etc., concrete can obtain this orientation angles information by electronic compass.
Whether surpass outside the default numerical range at the changing value of judging acceleration value, whether the changing value that can also judge the orientation angles of training vehicle in this Preset Time surpasses preset value, the changing value of the acceleration value of this training vehicle exceeds default numerical range within the schedule time, and the changing value that should train the orientation angles of vehicle also surpasses preset value, thinks that then described vehicle is in transport condition.That is to say, judging vehicle in foundation acceleration value difference is in outside the transport condition, for the accuracy of the vehicle running state that guarantees to judge, can also verify further whether vehicle is in transport condition by the orientation angles information of judging the training vehicle.
When obtaining the acceleration value of training vehicle, can also obtain the velocity information of training vehicle, and whether the velocity amplitude of further judging the training vehicle that gets access to is greater than zero, the difference of the acceleration value of described training vehicle surpasses default numerical range within the schedule time, and velocity amplitude that should the training vehicle thinks that then described moving vehicle is in transport condition greater than zero the time.
Certainly, can be when obtaining training vehicle acceleration value, obtain orientation angles information and the velocity amplitude of training vehicle, and the changing value that surpasses default numerical range, orientation angles when this changing value of training the acceleration value of vehicle surpasses default scope, and velocity amplitude judges that then vehicle is in transport condition greater than zero the time.
