AI Technical Summary

Problems solved by technology

Especially in cities where there are more speed limits, and many drivers often unconsciously over-press the accelerator, resulting in excessive speed
When you realize that the speed is too fast, you have to step on the brakes. Such frequent operations are quite fuel-intensive.

Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0026] Such as figure 1 As shown, the present invention is mainly composed of a single chip microcomputer 10, a detection unit 30, a function display unit 40, a key unit 20, a drive unit 50 and corresponding connection circuits. Human-computer interaction is performed through the function display unit 40 and the key unit 20, data selection is performed through the single-chip microcomputer 10 and the detection unit 30, control is performed through the engine control unit 51 in the drive unit 50, and specific speed is limited through the opening of the throttle valve 52. Such as figure 1 As shown, different scenario simulations will lock different maximum throttle openings, that is, corresponding to different maximum speeds, which can not only...

Abstract

The invention relates to a driving scene simulation system for an automatic-transmission vehicle and a control method, and belongs to the technical field of vehicles. The driving scene simulation system for the automatic-transmission vehicle comprises a single chip microcomputer, a detection unit, a function display unit, a key unit and a driving unit, wherein the detection unit, the function display unit, the key unit and the driving unit are connected with the single chip microcomputer. The single chip microcomputer comprises a detection selecting unit, a mode selecting unit, an output unit and an information processing unit. The input end of the mode selecting unit is connected with the key unit, the output end of the mode selecting unit is connected with the detection selecting unit and the information processing unit, and the output end of the detection selecting unit is connected with the input end of the detection unit. By selecting different scene simulation modes, the maximum opening of a throttle valve is preset in an engine control unit, the effect that the vehicle speed is not higher than a limited speed even if a pedal is treaded to the maximum extent is guaranteed, and thus the purposes of oil saving and safety are achieved.

Description

technical field [0001] The invention relates to a scene simulation control system for automobiles, in particular to a driving scene simulation system and a control method for an automatic transmission vehicle. Background technique [0002] Now automatic transmission vehicles are becoming more and more popular. From the perspective of advanced countries in automobile development, most vehicles have already transitioned to automatic transmission. It is the trend of automobile development that automatic transmission replaces manual transmission and becomes the main model for daily driving. When driving an automatic transmission car, the automatic transmission will automatically shift gears according to the driver's needs. If you step on the accelerator, the automatic transmission will generally downshift to increase the power output. After loosening the throttle, the automatic transmission will generally upshift to reduce fuel consumption. [0003] Different driving modes, s...
