Abstract
The utility model discloses an automobile engine management system which comprises a throttle control, an engine controller, a sensor, and an air throttle arranged in an air inlet pipe of an engine. The air throttle is an electronic air throttle, the throttle control is an electronic throttle control, the electronic air throttle and the electronic throttle control are both connected with the engine controller, the automobile engine management system also comprises an air flow meter connected with the engine controller, and the air flow meter is also arranged in the air inlet pipe of the engine. The engine controller in the utility model controls the opening of the electronic air throttle according to the set control way through collecting the signals of the throttle control, the air flow meter and other sensors, compared with the traditional mechanical air throttle control way, the way is more precise and reasonable. Due to the adoption of the air flow meter, the air flow in the air inlet pipe can be measured accurately, thereby the control for the engine can be more accurate.
Description
Technical field
The utility model relates to automobile dynamic system, is specifically related to the configuration of automobile engine management system.
Background technique
In the existing automobile engine management system,, usually select several modes and structure for use: 1) mechanical type closure+pressure-temperature sensor+other sensor in order to improve the emission performance of automobile.As shown in Figure 1, mechanical type closure 2 is arranged in the suction tude 1 of motor 7, and directly control by throttle control 3, pressure-temperature sensor 8 also is arranged in the suction tude 1 and with engine controller 4 and is connected, and other sensor 5 also is connected with engine controller 4, though this structure has lower-cost advantage, but it is because simple in structure, profile is bigger, and function is limited, is difficult to satisfy the accurately requirement of control of high-end motorcar engine; 2) electronic throttle+pressure-temperature sensor+other sensor.Though this mode has been used electronic throttle instead, realized the optimization control of motor to power performance, but because pressure-temperature sensor is comparatively responsive to the suction pressure fluctuation, measuring accuracy to engine intake airflow is lower, so Economy and the discharging when low speed, the running on the lower load improves little for motor.
The model utility content
The technical problems to be solved in the utility model provides a kind of novel engine management system, to improve power character, Economy and the emission performance of motor.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of automobile engine management system, comprise throttle control, engine controller, sensor and be arranged on closure in the engine air inlet tube, described closure is an electronic throttle, described throttle control is the electronic throttle pedal, described electronic throttle, electronic throttle pedal all are connected with engine controller, also comprise an Air flow meter that is connected with engine controller, Air flow meter also is arranged in the suction tude of motor.
Preferably, described Air flow meter is arranged on the upstream of electronic throttle.
Preferably, also comprise other sensor that is connected with engine controller.
Engine controller is by gathering the signal of throttle control, Air flow meter and other sensor in the utility model, according to the control mode of setting the aperture of electronic throttle is controlled, this mode is compared more accurate and reasonable with traditional mechanical type closure control mode.Owing to adopted Air flow meter, can accurately measure the air mass flow in the suction tude, thus also can be more accurate to the control of motor.Adopt this mode of structure that the cost of whole system is remained within the reasonable range simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a kind of structural representation of automobile engine management system of routine.
Fig. 2 be the utility model automobile engine management system structural representation.
1, suction tude 2, mechanical type closure 3, throttle control 4, engine controller
5, other sensor 6, outlet pipe 7, motor 8, pressure-temperature sensor
9, Air flow meter 10, electronic throttle 11, electronic throttle pedal
Embodiment
As shown in Figure 2, suction tude 1 is connected with motor 7 respectively with outlet pipe 6, and electronic throttle 10, Air flow meter 9 all are arranged in the suction tude 1, and Air flow meter 9 is positioned at the place ahead (according to the charge air flow direction) of electronic throttle 10.Electronic throttle 10 is connected with engine controller 4 with Air flow meter 9 simultaneously, and other sensor 5 also is connected with engine controller 4 with electronic throttle pedal 11.
The position signal of electronic throttle pedal 11 is converted to electrical signal, send to engine controller 4,4 whiles of engine controller are in conjunction with the signal of Air flow meter 9 and other sensor 5, according to corresponding control strategies, aperture to electronic throttle 10 is controlled, thereby the runnability of motor 7 is controlled.Because electronic throttle 10 no longer directly carries out mechanical connection with pedal, but all sensor signals at first are input to the controller of motor, control the aperture of electronic throttle 10 then by controller, thereby can realize more optimal control strategy, to improve emission performance.
