Detailed description of the invention
Below in conjunction with embodiment accompanying drawing, the utility model is described further.
Embodiment 1,1-3 describes by reference to the accompanying drawings.
For a circuit control system for car enforce idling, comprise Automobile brake control system 1 and ECU2 thereof, described ECU2 connects accel control 4 by oil circuit control circuit 3;
Described ECU2 has forced idling function, and after the arbitrary speed-slackening signal source 5 of Automobile brake control system 1 feeds back to ECU2, ECU2 controls accel control 4 action by oil circuit control circuit 3, cuts off oil circuit and throttle 11 was lost efficacy.
Described ECU2 also connects hand brake 6.
Described speed-slackening signal source 5 is Jake brake indicator signal 7 or brake lamp signal 8 or retarder control action signal 9 or brake actuating signal 10.
The relevant device parameter request that the utility model is implemented is as follows:
1. technical requirements:
Engine calls: the driving engine with driving engine forced idling function, the up-to-date Econtrols system engine in such as Yuchai;
Forced idling switching requirements: not reset switch, can adopt key type wane switch etc.;
Car load requires: vehicle brake signal (24V signal or low signal);
2. mode of operation: for the up-to-date Econtrols system engine in Yuchai:
Service brake 24v high level signal/or earth signal;
Retarder work 24v high level signal/or earth signal;
Jake brake instruction 24v high level signal/or earth signal;
Forced idling switch 24v high level signal/or earth signal;
Brake lamp/brake indicator lamp 24v high level signal/or earth signal.
Diode: diode forward voltage :≤1V;
Diode reverse voltage: >=80V;
Diode working current: >=250mA;
Further, be explained for the Yuchai mode of up-to-date Econtrols system engine to this circuit control system below:
First be automotive system identification and accept ECU and control forced idling function (if Fig. 3 is that existing automobile brake ECU electronic control unit controls idling schematic diagram), this function is originally gate forced idling function, namely, during car door opening, driving engine forced idling, does not allow vehicle acceleration; Secondly, with last speed-slackening signal respectively through forward diode (determining according to direction of current), ECU forced idling function stitch will be connect;
Mode is divided into following a few class (be below forget to step on clutch or no-clutch when):
(1) driving gas control for brake: in vehicle travel process, when stepping on brake pedal, force engine idle, the possibility caused the accident when reducing mis-accelerator pressing (braking accelerator is stepped on simultaneously);
(2) retarder controls: retarder has hand switch and braking airline pressure switch two kinds of modes, no matter which kind of mode, as long as by retarder working signal input Engine ECU, then driving engine forced idling, reduces power stage, and torque transmission shaft reduces, retarder braking function can be normal, ensure that traffic safety on the one hand, protect driving engine and retarder on the other hand, alleviate moment both when maloperation and oppositely damage is caused to vehicle;
(3) Jake brake indicator signal controls (energy brake or cylinder inside brake): driving engine is when braking, car load is advanced and produces very large resistance to reach the object of braking, and in braking procedure, forget or maloperation, the step on the accelerator when not killing engine brake switch, then often produce greatly negative effect to driving engine; Native system utilizes Jake brake signal, when it is braked, forces its idling, prevents maloperation and forgets the loss brought;
(4) brake lamp signal: utilize stoplight stop lamp signal as control, provide and in many ways ensure, increases reliability, improves safety index;
(5) rocker switch: native system also add forced idling switch on above basis, opens switch, driving engine forced idling, be used for solution of emergent event time, phenomenon of taking throttle as brake is stepped on, situation about not touching on the brake by mistake;
Above-mentioned various signal, after arbitrary speed-slackening signal source 5 feeds back to ECU2, ECU2 controls accel control 4 action by oil circuit control circuit 3, cuts off oil circuit and throttle 11 was lost efficacy, make automobile carry out idling.
Each mode implementation method is simple above, and except the 5th forced idling switch needs chaufeur to do out operation, press switch, all the other controls all do not need chaufeur to make additional act, without troublesome operation flow process, simple and practical during reply emergency situations.
The present embodiment does not have specifically described part all to belong to common practise and the known technology of the art, and we can provide bibliography if needed.
More than exemplifying is only to casehistory of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
