Engine pedestal to mark method.
Background technology
It is common technological means in automotive performance development process to mark testing experiment, competing product vehicle is obtained by the experiment
All kinds of performance datas of type or high-performance vehicle can be used for developing the performance indicator formulation, Properties Control reference and property of vehicle
It can perpendicular evaluation.Vehicle is easier mark testing experiment, and special change need not be carried out to vehicle, straight according to test specification
Row experimental test is tapped into, but as the engine of vehicle kernel component, then has great difficulty to mapping examination.
Engine test test need carried out on Special-purpose bench, and the igniting of engine and various operating modes operation be all by
Electronic control unit (ECU) is controlled.That routine test engine uses is all rack ECU, and it comprises all start
Machine itself function, can make engine be operated in all operating condition of test.But to mapping examination object be all other producers
Engine is listed, its rack ECU is not got, under these conditions, can only use object engine under vehicle carrying state
ECU (abbreviation vehicle ECU), controls the igniting and operation of engine.But vehicle ECU is very different with rack ECU, in addition to starting
Outside machine itself control function, vehicle ECU has the communication function with vehicle other systems, and can also directly read part vehicle end
Sensor information, it can run shape according to logic of propositions according to the status information of these sensors and interconnected system to engine
State is adjusted or limits.If vehicle ECU detects the sensing that other interconnected systems do not have normal operation or needs to read
Device signal deletion can then control engine and enter fault protection scheme, and engine can limit rotating speed, limitation torque or even cannot point
Fire.
With the progress of automobile integral level, logical relation is even closer between each system of vehicle, influences engine ignition
The Correlation Criteria of operation is more and more, and vehicle is more high-grade, and interconnected system is more, and it is also more complicated to influence logic.It is common at present
Engine operation vehicle limiting factor have wheel speed speed, gearbox speed, gearbox-gear, vehicle sensor signal, these
The mistake (not in the reasonable scope or missing) of signal directly or indirectly (will pass through brake and transmission system) limitation hair
The normal operation of motivation.
So when using vehicle ECU to carry out engine on rack to test mark, due to lacking vehicle other interconnected systems
With vehicle sensor signal, engine is then not normally functioning or even cannot light a fire.
In addition routine test engine is the power supply for using simplified rack harness to ensure each electric parts of engine, and right
Mark test engine does not have available rack harness, and platform harness needs are fabricated separately and take a significant amount of time for starting machine electric appliance
Part and the definition of the front lines ECU measure, harness is analyzed and make work.In conclusion to mark engine use vehicle ECU when,
It, cannot be as using the engine of common rack ECU just due to lacking other interconnected systems of vehicle and vehicle sensor signal
Often igniting operation, this severely limits engine pedestals to carry out mark experiment.To solve the above problems, this patent provides one kind
Engine pedestal based on vehicle dry run to mark method, with solve to mark engine be not normally functioning on rack and
