Embodiment 1

[0040] The invention provides an intelligent electronic accelerator control system, comprising: an electronic accelerator pedal connected in sequence, an accelerator position sensor, an intelligent control system, an ECU and a throttle control system; the accelerator position sensor is used to identify the position of the electronic accelerator pedal, and the intelligent control The system collects the analog signal transmitted by the throttle position sensor, and after processing, generates a corresponding analog signal and transmits it to the ECU. The ECU controls the throttle opening according to the corresponding analog signal and then controls the engine fuel injection amount.

[0041] The intelligent control system includes:

[0042] Power management: supply power to each component of the intelligent control system;

[0043] Display screen: connected to the processor, used as a man-machine interface to display the maximum throttle value, minimum throttle value, maximum a...

Embodiment 2

[0057] As a supplement to Embodiment 1, the implementation method of the intelligent electronic throttle control system specifically includes: steps for realizing the minimum throttle limit function, which can improve the idle speed of the vehicle. Specifically:

[0058] Assume that the minimum analog voltage value output by the accelerator position sensor is P. When the system is working normally, set the minimum accelerator value to the analog voltage value Q, Q>=P; when the electronic accelerator pedal is stepped on, the accelerator position sensor outputs the corresponding analog voltage value b; the intelligent control system collects b value:

[0059] When b>Q, the processor controls the normally closed contact of the relay to be connected to the common contact; the intelligent control system transmits the b value to the ECU, and the ECU controls the throttle opening according to the collected b value and then controls the engine fuel injection amount ;

[0060] When b...

Embodiment 3

[0063] As a supplement to Embodiment 1 or 2, the implementation method of the intelligent electronic accelerator control system specifically includes: the implementation steps of the maximum acceleration limit function, which can prevent the accelerator from being stepped on by mistake when the brake is stepped on, and the driver panics and makes mistakes when an emergency occurs. When the accelerator pedal is used as the brake pedal, the foot will always be pressed to the bottom. At this time, the value of c will be very large, far exceeding the preset value C. The system will ignore this acceleration operation and still output the value of x to the ECU, so that The vehicle will not be able to effectively prevent incorrect operation to protect the safety of the driver and passengers.

[0064] Specifically: when the system is working normally, set the maximum acceleration value to C; when the electronic accelerator pedal is stepped on, within t seconds, the electronic accelerat...

Abstract

The invention discloses an intelligent electronic throttle control system and a realization method thereof. The intelligent electronic throttle control system comprises an electronic throttle pedal, a throttle position sensor, an intelligent control system, an ECU and a throttle valve control system connected in sequence; the throttle position sensor is used for identifying the position of an electronic throttle pedal; the intelligent control system acquires simulation signals transmitted by the throttle position sensor for processing to generate corresponding simulation signals to transmit to the ECU; and the ECU controls openness of a throttle valve according to the corresponding simulation signals so as to control the oil injecting quantity of an engine. The intelligent electronic throttle control system guarantees to recover the vehicle throttle control to a factory delivery control mode under the condition of power failure, and adopts a double-redundancy design to guarantee the vehicle driving safety.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an intelligent electronic throttle control system and its realization method. Background technique [0002] The electronic accelerator is also called the electronically controlled accelerator (E-Gas). In the engine control system equipped with the electronic accelerator, the mechanical connection between the accelerator pedal and the throttle valve is canceled, and the position sensor of the electronic accelerator pedal of the vehicle detects the position of the accelerator pedal. The sensor module of the automotive electronic accelerator pedal converts the pedal position signal into an electrical signal and transmits it to the engine electronic control unit, and the engine electronic control unit controls the throttle to realize the driver's control of the engine torque. [0003] At present, the known automobile gas pedal and brake all independently complete the...
