Description

Accelerator pedal limiting method and device based on electromagnetic induction and terminal equipment
Technical Field
The invention relates to the field of automobile power, in particular to an accelerator pedal limiting method and device based on electromagnetic induction and terminal equipment.
Background
With the continuous development of economy, more and more people buy automobiles to save the time on the way, but the problems of automobile oil consumption and automobile safety are followed. The influence factors of the automobile fuel consumption are many, and the automobile condition, the road condition, the driving behavior of a driver and the like are very common; the vehicle conditions comprise vehicle performance, driving force, horsepower, load-weight ratio, mileage, vehicle age and the like, and the fuel consumption of the vehicle with poor vehicle conditions is high; the road conditions comprise the gradient, the altitude, the telling, the congestion condition, the road surface quality and the like of the road, and the oil consumption of the automobile can be increased due to the poor road conditions. The influence of the driving behavior of a driver on the fuel consumption of the automobile accounts for 25%, and in the analysis of the driving behavior of the driver, the sudden stepping on of the accelerator is an important reason for increasing the fuel consumption. The action change of 'suddenly stepping on the throttle' can cause the transient oil consumption of the engine to surge, thereby causing the oil consumption to increase. In addition to increasing fuel consumption, the sudden accelerator stepping is also easy to cause the safety accident of vehicle collision, so the behavior of sudden accelerator stepping needs to be corrected.
For a method for preventing sudden stepping on an accelerator, the prior art 1: the method for preventing mistaken stepping on the accelerator by utilizing the reaction force of the magnet and the balance iron (CN201110321221.5) is characterized in that a mechanical connecting structure between the accelerator pedal and the brake pedal is constructed, and when a driver quickly steps on the accelerator pedal, the accelerator is prevented from being increased through the mechanical connecting structure and the brake is carried out, so that the automobile is emergently braked. Whereas prior art 2: the safety device (CN202021442044.7) for preventing the automobile from suddenly stepping on the accelerator pedal limits the change speed of the accelerator pedal through a hydraulic device, and when a driver suddenly steps on the accelerator pedal, a liquid flow channel cannot be quickly pressed down due to the fact that the flow is limited, so that the change speed of the accelerator pedal is reduced.
The inventor finds that the behavior of 'sudden stepping' in the prior art 1 is not judged, when the driver intends to overtake on a crowded road, the driver can suddenly step on an accelerator to accelerate and overtake the vehicle, but the prior art 1 forcibly triggers a brake, so that a safety accident is caused; the hydraulic device in the prior art 2 has the risk of leakage, and is low in safety and stability.
