Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, a kind of engine load controller, comprise housing 1, in housing 1, printed board 3 is installed, printed board 3 is installed power module 2, this power module 2 is socket, power module 2 carries power supply respectively to the communication module 4 be installed in printed board 3, driver module 6, control module 5, communication module 4, power module 2 and driver module 6 is in same straight line, communication module 4 utilizes serial ports to be connected with described control module 5, and driver module 6 utilizes I/O mouth to control to be connected with control module 5.
Specific works process of the present utility model is as follows:
First above-mentioned communication module 4 is connected with Engine ECU with CAN, driver module 6 is connected with external display module (not shown), by after voltage from 12-24V to power module 2 that provide, power module 2 is to communication module 4, driver module 6 and control module 5 provide the electric current of 5V respectively, by communication module 4 and CAN from collection signal in Engine ECU, this signal is specially long-range gas pedal aperture, the outer moment of torsion of engine, engine test bench characteristic moment of torsion, friction torque percentage, reference torque, engine torque pattern etc., after collecting above-mentioned signal, communication module 4 (refers to pass through data signal line by serial communication, a kind of mode transmitting data of ground wire or control line) send to control module 5 to carry out engine load rate, the computational analysis of external characteristics moment of torsion and driving demand torque, obtain the loaded-up condition that engine is current.Control module 5 preserves all rate of load condensate summations in first 30 seconds simultaneously, then averages.
The loaded-up condition of above-mentioned engine is made up of three parts, comprise Light Condition, in carry state and heavy condition, it is as follows that the judgement of engine load state and moment of torsion export control flow: as shown in Figure 4, when after engine start, control module 5 is analyzed the signal collected, and real-time calculated load rate.A1 represent when meet average load rate >80%, rate of load condensate >40% and in gas pedal aperture >=95% and in the past 3s average load rate higher than 45% and accelerator open degree is all greater than the arbitrary condition in 90% time, change heavy condition into by Light Condition; When A2 represents by controlling average load rate≤60%, heavy condition changes Light Condition into again; Simultaneously when Light Condition, when B1 represents that meeting the demand torque of 10s driving is in the past greater than 60% current external characteristics moment of torsion, then Light Condition carries state in changing into; A state of carrying in the middle of B2 represents is when meeting average load rate≤60%, in carry a state transfer be Light Condition.In carry state time, C1 represent when meet average load rate >80%, rate of load condensate >65% and in gas pedal aperture >=95%, past 3s average load rate higher than 65% and accelerator open degree is all greater than 90%, past 10s drive demand torque be greater than the arbitrary condition in 80% current external characteristics moment of torsion time, in carry a state transfer be heavy condition; C2 represents when controlling average load rate and being less than or equal to 80% and being greater than 60% (60%< average load rate≤80%), carries state during heavy condition changes into.
Control module 5 sends moment of torsion output control signal by wearing mouth to communication module 4 according to above-mentioned flow process, by communication module 4, signal is sent to Engine ECU by CAN simultaneously, thus realizes the control to engine output torque.Control module 5, while transmission torque control signal, controls driver module 6 by I/O mouth and shows corresponding loaded-up condition.
Above-mentioned power module 2, communication module 4, control module 5 and driver module 6 are existing known technology and structure.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
