Description
Technical field
The invention belongs to automobile technical field, what be specifically related to is a kind of vehicle error comprehensive diagnosis method.
Background technology
Along with Modern New automotive electronic technology is more and more applied, the controller in automobile is also more and more, and vehicle breaks down and is also more and more difficult to find.Most automobile is to adopt the mode of combination instrument pilot lamp to judge the state of automobile, but a lot of drivers itself not quite understand the implication of meter lamp, only knowing that pilot lamp is bright represents that automobile breaks down, but and do not know that what fault is concrete fault be, more do not know that vehicle failure is seriously not serious, and whether larger on running car impact.Except aforesaid way, also can adopt diagnostic device to diagnose, but the vehicle diagnostics equipment in reality is mostly directly to judge which automobile fitting part broken, be mainly serious at damage comparison or find when failure ratio is obvious, and for the decline of automotive performance and hidden problem, car owner differs and finds in time surely.
Summary of the invention
For this reason, the object of the present invention is to provide a kind of vehicle error comprehensive diagnosis method, by arriving in igniting of vehicle in the flame-out cycle, various parameters to steering vehicle are carried out analyzing and processing, and form vehicle comprehensive diagnos result, so that car owner can intuitively clearly understand the state of vehicle, can not understand in time vehicle performance and find the problem of vehicle trouble to solve current car owner.
The object of the invention is to be achieved through the following technical solutions.
A kind of vehicle error comprehensive diagnosis method, comprising:
S1, set vehicle drive type: set instantaneous oil consumption lower than " m liter/hundred kilometer " for greenly driving, instantaneous oil consumption higher than n liter/hundred kilometer for redly driving, instantaneous oil consumption is between the yellow driving between m liter/hundred kilometer and n liter/hundred kilometer;
S2, the each igniting of setting vehicle are a Trip cycle to stopping working;
S3, obtain speed, engine speed, mileage and the instantaneous fuel consumption information of vehicle within the above-mentioned Trip cycle by OBD;
S4, calculate green time of driving and distance, red time of driving and distance, anxious give it the gun time and distance and anxious Reduced Speed Now time and distance;
S5, the operating range that calculates the above-mentioned Trip cycle and time;
S6, calculate economy run mark and safe driving mark according to above-mentioned data, output vehicle comprehensive diagnos result.
Preferably, the method also includes:
Set the every 200 milliseconds of collections of instantaneous oil consumption once, and in 1 second gather instantaneous oil consumption be designated as a1, a2, a3, a4 and a5, the average fuel consumption in this 1 second is A=(a1+a2+a3+a4+a5)/5; If A < is m, judges within this second and drive for green; If A > is n, judges within this second and drive for red; If between m and n, judging in this second, drives for yellow A;
Set the every 200 milliseconds of collections of the speed of a motor vehicle once, the speed gathering in 1 second is designated as s1, s2, s3, s4 and s5, the speed unit gathering be " kilometer/hour ", the driving distance in this 1 second is designated as S=(s1+s2+s3+s4+s5)/5*1000/3600, unit is meter; Red driving distance is designated as S (red), and green driving distance is designated as S (green), and its initial value is 0;
According to A and the S value obtained with upper type in every 1 second, if A < is m, S (green) increases S; If A > is n, S (red) increases S.
The present invention compared with prior art, beneficial effect is: vehicle error comprehensive diagnosis method provided by the invention, speed by OBD within the Trip cycle, engine speed, mileage and instantaneous fuel consumption information, then carry out comprehensive data analysis according to the driving type of setting, thereby draw economic mark and the safe driving mark driven, provide vehicle comprehensive diagnos result, so that car owner can grasp the performance change of vehicle the moment, find the hidden problem of vehicle, make vehicle can obtain timely M R, reduce the risk of vehicle generation catastrophic failure.
