Embodiment Construction

[0030] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.

[0031] Such as figure 1 As shown, an automatic throttle opening control system based on a stepping motor, including:

[0032] Accelerator pedal position sensor: used to generate the voltage signal of the accelerator pedal position and transmit it to the throttle control unit ECU;

[0033] Throttle control unit ECU: receives the voltage signal transmitted by the accelerator pedal position sensor, and outputs the voltage signal of the stepping motor;

[0034] Stepping motor: control the opening of the throttle according to the voltage signal of the stepping motor output by the throttle control unit ECU;

[0035] Throttle position sensor: Feedback the throttle opening signal to ...

Abstract

The invention relates to a stepping motor-based automatic control system for an open degree of a throttle gate of an automobile. The system comprises an accelerator pedal position sensor for generating a voltage signal of the accelerator pedal position and transmitting the same to a throttle gate control unit ECU; the throttle gate control unit ECU which receives the voltage signal transmitted by the accelerator pedal position sensor and outputting a voltage signal of the stepping motor; the stepping motor which controls the open degree of the throttle gate according to the voltage signal of the stepping motor output by the throttle gate control unit ECU; and throttle gate position sensor which feeds an open degree signal of the throttle gate back to the throttle gate control unit ECU. When a driver operates the accelerator pedal, the throttle gate control unit ECU controls the open degree of the throttle gate according to the voltage signal of the accelerator pedal position sensor, so that an engine outputs the optimum torque. The air-fuel ratio can be precisely controlled, and hysteresis of the accelerator is remarkably improved, so that the emission performance of the engine is further improved.

Description

technical field [0001] The invention relates to a throttle control device for an automobile engine, in particular to an automatic control system for the throttle opening of an automobile based on a stepping motor. Background technique [0002] Normally, the flow of the combustible mixture can be controlled by manipulating the opening of the throttle, and the speed and power of the engine can be changed to meet the needs of the car. In general, the throttle opening depends entirely on the position of the accelerator pedal, that is, the driver's operating intention. In this case, the engine is not always running optimally, and the driver's misuse can also pose a safety hazard. For this reason, it is very necessary to find a device that can automatically control the throttle opening of the automobile and significantly improve the hysteresis phenomenon of the throttle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provid...
