Abstract
The invention relates to a vehicle speed signal simulation method for a benchmarking test of an engine bench, which comprises the following steps: connecting a positive pole of a signal generator matched with signal characteristics of a vehicle speed sensor with a signal wire of the vehicle speed sensor, connecting a negative pole with an engine body, calculating vehicle speed corresponding to the rotational speed of an engine and input frequency f of the signal generator corresponding to a vehicle speed signal according to a formula, starting the engine, running the engine to the test rotational speed, simultaneously giving working frequency corresponding to the rotational speed of the engine to the signal generator, and leading the vehicle speed sensor to send the vehicle speed signal received from the signal generator to an ECU (electronic control unit). The method can accurately simulate the vehicle speed signal and send to the ECU, thereby leading the benchmarking test of the engine of a vehicle to carry out normally.
Description
Technical field
The invention belongs to the automobile technical field of measurement and test, be specifically related to a kind of engine pedestal to the method for mark test simulation GES.
Background technology
In car engine rack was tested mark, when the engine speed height was spent to certain range of driving, if there is not GES, automobile ECU will be in guard mode and make engine stop work, thereby caused engine that mark is tested and can not normally be carried out。At this moment, normally carry out if engine is tested mark, just must input GES to automobile ECU, but can't obtain GES in the testing ground at present, so make engine test and normally to carry out mark.
Summary of the invention
The purpose of this invention is to provide a kind of engine pedestal to the method for mark test simulation GES, make the car engine machine test and normally to carry out mark.
Engine pedestal of the present invention to the method for mark test simulation GES is:
A, on to the mark vehicle, utilize oscillograph to detect the signal feature of vehicle speed sensor;
B, will to the mark car engine be installed on the automotive engine test bench, engine is powered on, whole car firing key place " ON " shelves;
C, utilize universal meter to judge vehicle speed sensor signal line, select the signal generator that mates mutually with vehicle speed sensor signal feature, signal generator positive pole is linked to each other with vehicle speed sensor signal line, signal generator negative pole links to each other with engine body;
D, calculate corresponding to the speed of a motor vehicle v of engine speed and the input frequency f of the corresponding signal generator of this GES according to following formula:
v=0.0001885kn/m(km/h)；
f=6.89v；
Wherein n is engine speed, and k is wheel width (mm) * (wheel high wide ratio/100) * 2+ wheel hub diameter (inch) * 25.4, and m is the final gearratio * respective notch gearratio of engine speed changer;
E, startup engine move to the test rotating speed with engine, give simultaneously the work frequency of the corresponding engine speed of signal generator, and vehicle speed sensor will be issued ECU from the GES that the signal generator receives.
For a specific automobile, tire specification, final gearratio are the parameters of fixing, and for a certain gear, its gearratio is also fixed, therefore, as long as the rotating speed of known gear and engine can be obtained the corresponding speed of a motor vehicle.
The signal generator sends to vehicle speed sensor with GES under the work frequency that adapts with engine speed, vehicle speed sensor is issued ECU with this GES, thereby guarantee that engine normally moves, at this moment, the GES that ECU obtains is the GES of engine when its rotating speed just.
The method of the invention is implemented simple, and institute's use equipment is few, can accurately simulate the GES of engine when certain rotating speed, guarantees the normal operation of engine, thereby makes the car engine machine test and can normally carry out mark.

Now by reference to the accompanying drawings the present invention is described in further detail.
Fig. 1 is that the connection of each equipment in the method for the invention concerns schematic diagram.
Concrete enforcement mode
As shown in Figure 1, this engine pedestal to the method for mark test simulation GES is:
A, on to the mark vehicle, utilize oscillograph to detect the signal feature of vehicle speed sensor 2;
B, will to the mark car engine 4 be installed on the automotive engine test bench, engine 4 is powered on, whole car firing key place " ON " shelves;
C, utilize universal meter to judge vehicle speed sensor 2 signal lines, select the signal generator 1 that mates mutually with vehicle speed sensor 2 signal features, signal generator 1 positive pole is linked to each other with vehicle speed sensor 2 signal lines, signal generator 1 negative pole links to each other with engine 4 bodies;
D, calculate corresponding to the speed of a motor vehicle v of engine speed and the input frequency f of the corresponding signal generator 1 of this GES according to following formula:
v=0.0001885kn/m(km/h)；
f=6.89v；
Wherein n is engine speed, and k is wheel width (mm) * (wheel high wide ratio/100) * 2+ wheel hub diameter (inch) * 25.4, and m is the final gearratio * respective notch gearratio of engine speed changer;
E, startup engine 4, engine 4 is moved to test rotating speed n, give simultaneously the work frequency f of signal generator 1 corresponding engine speed, vehicle speed sensor 2 will be issued ECU3 from the GES that signal generator 1 receives, it is corresponding with engine speed that then vehicle speed sensor 2 is issued the GES of ECU3, engine 4 can normally move, thereby makes the car engine machine test and can normally carry out mark.
