Description of drawings
Shown in the drawings and the further elaboration of do in following explanation of embodiments of the invention.Wherein:
Fig. 1 is based on the example of travel conditions of the present invention;
Fig. 2 is based on the example of the kinematic operating data that method of the present invention obtains;
Fig. 3 is the diagram of circuit of embodiment according to the method for the invention; And
Fig. 4 is the scheme drawing that is suitable for implementing the embodiment of device according to the method for the invention.
The specific embodiment
The vehicle (2) that is positioned on the track (F) is shown at the travel conditions shown in Fig. 11.This vehicle has at least one controller (3) and at least one sensor (4).Possible sensor (4) can for example obtain the wheel pulse counter signals, be used for that the position is confirmed and/or the signal of timing.This signal can for example be a gps signal.
By the sensing data of at least one sensor (4) of obtaining in motion, in controller (3), obtain kinematic operating data.In Fig. 1, vehicle (2) moves ahead with speed (V1).The speed (V1) of vehicle (2) by the sensing data that is obtained for example from the position (P1) of constantly (T1) with obtain in the difference of the position of (T2) constantly.From these data, also for example obtain the acceleration/accel of vehicle (2).
In controller (3), the characteristic data of the vehicle (2) that kinematic operating data is interior with being stored in controller (3) is compared.These characteristic datas comprise parameter such as car weight, maximum speed, torque peak, peak acceleration, transmission system gear shift ratio and/or the power level that at least one vehicle is specific, and wherein parameter also can be confirmed according to chaufeur.
From this comparison, discern the incredible operating data of vehicle (2).If identify incredible operating data, then take a kind of measure at least.Measure can for example be by chaufeur stop vehicle (2) other starting, close the single parts of vehicle (2) or stipulate that velocity limit and/or the vehicle (2) of vehicle (2) move under the operational mode of urgent operation.
The sensor that also can additionally utilize existence for example speed sensor comes the kinematic operating data of obtaining is carried out the confidence level analysis.
Another kind of measure can be the result of storage contrast, is the mistake of form so that for example when maintenance and/or quality guarantee requirement, can confirm to identify with incredible operating data.To this, data and/or the kinematics data relevant with time and/or place are stored.The time length that for example surpasses maximum speed and/or peak acceleration by the time length of specific maximum speed of the verifiable vehicle of data relevant and/or peak acceleration with time and/or place.The data of obtaining also can only be obtained in the current driving circulation, preferably do not carry out the storage through controller (2) then.
Another measure can also be the prompting of chaufeur being made optics, acoustics and/or image, and this prompting reminds chaufeur to change.What also can want to imagine is that for example after prompting and inquiry chaufeur, possible vehicle launch is just undertaken by chaufeur after the success confirmation of inquiry.
Fig. 2 for example illustrates according to the result about the operating data of distance (S) (solid line among Fig. 2) monitor vehicle (10) of the process of the speed (V) (pecked line among Fig. 2) of time (T), the vehicle obtained and acceleration/accel (A) (dotted line among Fig. 2).Speed (V) is a differentiate of distance (S), and acceleration/accel (A) is the secondary differentiate of distance (S) function.At constantly (T1) and position (T2) (P1) and (P2) recording on the distance of process (S) and the axis of time (T) shown in Fig. 1.In this example, vehicle moves with almost constant speed V1 in time period T2-T1 at position (P1) with (P2).The speed of vehicle (2) is at definable maximum speed (V
Max) in.In the moment (T4) later on, this maximum speed is exceeded, thereby can draw parts and change.At another moment (T3), the maximum specific acceleration/accel (A of vehicle
Max) be exceeded.
As substituting the incredible operating data that also draws definite member by the characteristic of confirming of for example velocity amplitude and/or accekeration.In an example,, in the piston-engined intake stroke of supercharging, water-alcohol-compound is ejected in the combustion air in order to improve the power of combustion engine.In the method, except power raise, oxides of nitrogen reduced, thereby the characteristic of confirming of deviation between operating data and the vehicle data occurred.
The possible measure that be used to improve power, has definite characteristic be for example increase free air diffuser and/or valve and/or make that it is smooth, the other camshaft of packing into, polishing or milling cylinder top or cylinder block to be to improve compression.
Fig. 3 illustrates a kind of possible diagram of circuit according to the method for the invention.In step (10), when going the circulation beginning, start this method.
Obtaining in step (20) of the sensing data of at least one sensor carried out.Thisly obtain serially or implement constantly in that the on-cycle that goes is different.
If obtained sensing data, then in step (30), draw kinematic operating data.
In another step (40), kinematic operating data is compared with the characteristic stored data.These characteristic datas preferably are stored in the controller and comprise the specific parameter of at least one vehicle for example car weight, maximum speed, torque peak, peak acceleration, transmission system gear shift ratio and/or power level and/or the limit value definite according to chaufeur.
Incredible operating data is discerned through deviation between the ability predetermined characteristics data of kinematic operating data and vehicle, that be positioned at outside the ability predetermined threshold value.
In step (50),, when identifying incredible operating data, in step (60), take at least a measure according to comparison from step (40).Measure can for example be the other starting that stops vehicle, the single parts of closing vehicle; Velocity limit and/or the vehicle that can also stipulate vehicle move under the operational mode of urgent operation.Other measure is the result of storage contrast, operating data that storing moving is learned, the user is carried out the prompting of optics, acoustics and/or image.When for example only the counting machine that how long occurs of calculation deviation should improve, also can abandon this result.To this, original result is dispensable.
If confirm not have incredible operating data, then checking in step (70), whether vehicle is also in the circulation of going.Circulation does not finish if go, and then further in step (20), obtains sensing data.If go loop ends, then this method finishes in step (80).
Fig. 4 illustrates the scheme drawing of first embodiment of device according to the method for the invention.At least one controller 301 is arranged in vehicle 300.To this controller 301 data are provided by at least one sensor 302.The sensor 302 (1), 302 (2) that other can also be arranged ... 302 (n).Sensing data can be directly via interface or alternatively be sent to controller 301 via the for example bus system of CAN bus.Controller comprises at least one memory device 306 that is used to store with process sensor data, kinematic operating data and vehicle data.Controller 301 at least one actr 305 of control.Other actr 305 (1), 305 (2) ... 305 (n) can for example be starter or pent parts.For example for mode and chaufeur interaction with inquiry and prompting, vehicle 300 or controller 301 also can have other interface 307.
