Description
Technical field
The utility model relates to truck crane motor MAP controller, belongs to technical field of engine control.
Background technique
At present, prior art is the intelligence/manual multistate switch (multifunction switch) of engine control, and the principle of intelligence/manual multistate switch is by restriction Maximum Torque, external characteristics is restricted on part throttle characteristics.But intelligence/manual multistate switch has following shortcoming: (1), for truck crane, especially when getting on the bus equipment operation, does not play good oil-saving effect; (2) risk that motor stops working because moment of torsion is not enough on plateau can not yet be solved; (3) at present the monomotor MAP type of the medium and small tonnage truck crane of coupling is a lot, again can only demarcate, cause for same chassis when different regions work according to the demand of different client, or not fuel-efficient or moment of torsion not enough cause flame-out.
Model utility content
The purpose of this utility model is the above-mentioned defect overcoming existing intelligence/manual multistate switch existence, propose a kind of truck crane motor MAP controller, make truck crane more fuel-efficient when varying environment operation by motor MAP controller, when avoiding the regional operation of bad environments because of moment of torsion deficiency cause flame-out.
The utility model adopts following technological scheme to realize: the MAP controller that a kind of truck crane motor MAP controller comprises motor and is connected with environmental detection sensor, motor is provided with the MAP collection comprising some cover MAP, and MAP controller controls motor by testing environment parameter and engine rotational speed signal and switches different MAP.
Further, MAP collection is by switching condition corresponding to the environmental conditions free setting of different regions.
Further, MAP controller is positioned on the engine control system of truck crane.
Further, control signal comprises the tach signal of idle rotaring signal and the motor feedback controlling motor.
Further, the environment measuring parameter of environmental detection sensor comprises atmosphere pressure signal, hypo altitude signal and air density moisture signal.
The beneficial effects of the utility model are:
(1) truck crane motor MAP controller described in the utility model, theory structure is simple, and feasibility is higher.
(2) truck crane motor MAP controller described in the utility model, the demand of effectively operation under solution same truck crane adaptation different operating environment.
(3) truck crane motor MAP controller described in the utility model, according to the requirement in varying environment area, the MAP of real-time switching engine, reaches fuel-efficient or makes the effect of system stability.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the MAP controller that a kind of truck crane motor MAP controller comprises motor and is connected with environmental detection sensor, motor is provided with the MAP collection comprising some cover MAP, and MAP controller controls motor by testing environment parameter and engine rotational speed signal and switches different MAP.
MAP collection is by switching condition corresponding to the environmental conditions free setting of different regions; MAP controller is positioned on the engine control system of truck crane; Control signal comprises the tach signal of idle rotaring signal and the motor feedback controlling motor; The environment measuring parameter of environmental detection sensor comprises atmosphere pressure signal, hypo altitude signal and air density moisture signal.
It should be noted that, engine Map refers to the IGNITION CONTROL plotted curve that motor is required under various operating mode.
Using process of the present utility model is as described below: the utility model is applied on the power assembly system of medium and small tonnage truck crane (single motor), by the environmental detection sensor that a motor MAP controller connects, detect the environmental informations such as atmospheric pressure, hypo height, air density humidity, detect the tach signal of motor simultaneously, the MAP collection demarcated before motor is selected and switched, changes its idling speed to engine control signal simultaneously.
Such as, MAP1 is according to the regional development of low altitude area, normal atmosphere (An), there is idling moment of torsion little, the features such as economical consumption of fuel district is to the right, when truck crane is in MAP1 operation, and reduced the idling speed of motor by control gear, more fuel-efficient when making to get on the bus operation, and take into account chassis travel time fuel-efficient;
Such as, MAP2 is according to the regional development of High aititude, rarefied atmosphere pressure, there is idling moment of torsion large, the features such as economical consumption of fuel district is to the left, when truck crane is in MAP2 operation, and improved the idling speed of motor by control gear, can make truck crane be unlikely to during operation under rugged environment because of moment of torsion do not walk to cause flame-out.In sum, the mapping characteristics of motor changes by switching different MAP.
Certainly, foregoing is only preferred embodiment of the present utility model, can not be considered to for limiting scope of embodiments of the present utility model.The utility model is not limited in above-mentioned citing, and equalization change and improvement etc. that those skilled in the art make in essential scope of the present utility model, all should belong in patent covering scope of the present utility model.
