Intelligent device and method for remedying mis-operation of accelerator of vehicle

Abstract

The invention discloses an intelligent device and an intelligent method for remedying mis-operation of an accelerator of a vehicle. The device includes a personalized parameter self-learning module, an accelerator opening information acquisition module, a data synthetic analysis processing module, and an accelerator opening limit module, wherein signal output ends of the personalized parameter self-learning module and the accelerator opening information acquisition module are connected to a signal input end of the data synthetic analysis processing module. According to the invention, the device can obtain an adaptive function by self-learning; the problem that the misjudgment is caused by individual difference in driving habits and reaction capacity of drivers can be solved, and the problem that the vehicles have differentiation requirements for threshold values under different motion states can be solved, so that the recognition rate of accelerator mis-operation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a device and method for remediating the wrong step on the gas pedal of a smart car. Background technique [0002] In the driving process of an automatic transmission car, once the accelerator is mistakenly stepped on as the brake, it will directly cause the vehicle to produce a rapid movement contrary to the driver's expectation, resulting in an accident; Relatively large and urgent, so this type of accident is often serious, often causing casualties, and there are news of similar accidents almost every week. So this problem is a subject that needs to be solved urgently. [0003] At present, many experts, scholars and engineers and technicians have proposed various technical solutions to prevent misstepping (or misstepping and correcting errors), trying to solve this problem. Compared with the fixed threshold set by experience, the correct intention of the driver is obtained...

AI Technical Summary

Problems solved by technology

For example, for a driver who responds quickly, because the action of stepping on the accelerator is usually faster, it is easy to exceed the set data, resulting in a misjudgment that the accelerator is stepped on by mistake, resulting in a malfunction of the device, which will instead lead to other vehicles. Hidden danger of rear-end collision; for drivers who react slowly, when pedaling by mistake occurs, the device will not operate because the pedaling speed and other parameters have not reached the set value, thus losing the protective effect

[0005] On the other hand, since the vehicle needs different protection thresholds (or sensitivities) in different motion states, such as normal overtaking or when a traffic light turns red to green at an intersection, a large accelerator is required to accelerate, and a large threshold (sensitivity) is required. low); but when parking or reversing, due to the small space, it is easy to go wrong when the accelerator is large, and a small threshold (high sensitivity); therefore, if a unified threshold is used, it cannot be used in the above two motion states at the same time. To get good results, often lose sight of the other

[0006] To sum up, the current remedial methods for misstepping are not practical

At present, there are many patents related to misstepping on the accelerator. It can be seen that this type of product has a certain market space, but there is no such product in the domestic and foreign markets. This may be a circumstantial evidence that the current remedy for misstepping on the accelerator is not practical.
