Description

[0001] The present invention relates to a pedal movement measurement module for detecting sudden acceleration,

More particularly, the present invention relates to a sudden acceleration detection method, and more particularly, to a steering angle detection method and a steering angle detection method for detecting a sudden acceleration by detecting an angle of a pedal and an angle of a pedal using an ultrasonic sensor, To a pedal motion measurement sensor module.

Recently, vehicles have dramatically improved their performance and appearance, and they are evolving into next-generation vehicles that use various and convenient devices.

In addition to the evolution of such vehicles, a vehicle management system that manages and controls various mechanical devices and electronic devices applied to the vehicle, and on-Board Diagnostics (OBD) , And various systems and systems for providing entertainment are being combined.

As automotive systems evolved, errors that did not fit the user's intentions arose.

Sudden acceleration refers to the vehicle moving forward or backward without a driver's accelerator pedal and shifting operation in the starting state. When a situation occurs in which the vehicle advances or retreats by itself, there arises a situation where the vehicle is damaged, the driver of the vehicle, and the pedestrian walking on the road near the vehicle are facing a dangerous situation.

Since the sudden accident of such a vehicle occurs very instantaneously, the driver can not properly cope with it. In some cases, even if the braking device is driven, the speed of the vehicle can not be braked. Even if the braking device does not operate normally It also happens.

Many complaints have been filed against the sudden accidents of such vehicles, and various manufacturers and research and testing companies are analyzing the cause of the sudden occurrence in various angles, but the exact state information of the vehicle is detected It is presumed that this occurs due to a program malfunction of an electronic control unit (ECU) for controlling the corresponding operation.

Therefore, if witnesses are not secured in the event of a sudden emergence, it is impossible to know the situation at the moment of the accident, so that it is difficult to make an accurate judgment about the mutual statements between the parties about the cause of the accident.

In this case, police and insurance companies are having difficulties in making accurate judgments, and social costs such as lawsuits are increasing.

In order to prevent a vehicle from being suddenly developed, various vehicle sudden stop prevention systems have been developed. However, the existing vehicle emergency stop prevention system has not been developed as a separate module, and an on board diagnostic port (OBD terminal) It is difficult to attach and detach it.

As a result, there is a problem that the circuit inside the vehicle must be changed.
