A method and device for detecting misstepping on the accelerator of an electric vehicle

Abstract

The invention discloses an accelerator pedal misapplication detection method for an electric automobile. The accelerator pedal misapplication detection method for the electric automobile comprises the steps of acquiring real-time speed, accelerator pedal opening-degree information and steering wheel angle information of the electric automobile, and barrier information around the automobile; and detecting accelerator pedal misapplication of the electric automobile according to the real-time speed, the accelerator pedal opening-degree information and the steering wheel angle information of the electric automobile, and the barrier information around the automobile. The accelerator pedal misapplication detection method for the electric automobile provided by the embodiment of the invention is completely based on existing various parts and structures of the automobile, realizes information communication between controllers through a CAN network, and completely adopts a software manner to realize accelerator pedal misapplication detection; and meanwhile, according to the method, the overtaking intention of a driver can be intelligently recognized, the misjudgement of accelerator pedal misapplication is avoided, the structure is simple, and the implementation cost is low.

Description

Technical field [0001] The invention relates to the technical field of electric vehicles, and in particular to a method and device for detecting misstepping on the accelerator pedal of an electric vehicle. Background technique [0002] Traditional gasoline cars and electric cars use the throttle to control the power output of the vehicle, while the power output of the vehicle is only controlled by the throttle signal. Under normal driving conditions, drivers step on the accelerator pedal and the brake pedal slowly during driving. However, in an emergency, in order to quickly stop the car, the driver needs to brake urgently and step on the brake pedal. Since the brake pedal and accelerator pedal of the car are on the same side, the distance is very close, and both are controlled by the same foot of the driver. For many novices or in emergencies, it is easy to use the accelerator pedal as a brake pedal to step on, causing the vehicle to accelerate suddenly, causing many traffic a...

AI Technical Summary

Problems solved by technology

The method of preventing accidental stepping on the accelerator by limiting the accelerator through the mechanical structure has the following disadvantages: when a misoperation occurs, the driver often steps on the accelerator pedal hard, causing the mechanical structure to be stepped on frequently, which is easily damaged by aging, and then loses its original function; What's more, it will cause damage to the throttle system and affect normal driving.

[0004] At present, in the field of electric vehicles, there has not been in-depth research on the technology of false accelerator pedaling, so the related technologies are in urgent need of improvement
