Automatic control system capable of effectively preventing mistaken stepping on accelerator

Abstract

The invention discloses an automatic control system which is capable of preventing a driver from mistakenly stepping on an accelerator to cause a traffic accident. The automatic control system capable of effectively preventing mistaken stepping on an accelerator comprises a distance measurement module, a speed sensor, an acceleration sensor, a microprocessor and an audible and visual alarm, wherein the distance measurement module is used for measuring distance S between a self car and a front car or an obstacle, and the microprocessor calculates the current critical safe braking distance S0 according to information obtained by the speed sensor and a road sensor, assigns a safety factor a and marks a safe braking distance S1. When S is bigger than S0 and smaller than S1, the alarm sounds an alarm to remind the driver to take some measures. When S is smaller than S0, if the driver steps on the accelerator, an electronic control unit (ECU) comprehensively processes information acquired by the acceleration sensor and other system information, whether the driver mistakenly steps on the accelerator is judged, if the driver mistakenly steps on the accelerator, an instruction is output to adjust the opening degree of an air valve and cut off an oil supply system to enable the air valve to lose efficacy, and the fact that the car speeds up to move forward due to the fact the driver mistakenly steps on the accelerator in panic is avoided.

Description

[0001] technical field [0002] The invention belongs to the field of automobile safety, and in particular relates to a control system based on feedback control of vehicle distance and vehicle speed to prevent traffic accidents caused by a driver stepping on an accelerator by mistake. [0003] Background technique [0004] With the development of highway traffic, driving safety has also become a problem that people pay more attention to; in driving, traffic accidents are often caused by some unexpected situations or fatigue driving, lack of sight distance, etc.; When the situation is in a bad situation, the accelerator pedal is used as the brake pedal due to factors such as mental tension, which causes misoperation and causes traffic accidents. [0005] The patents related to anti-collision in the field of automobile safety do not consider the control method and device for preventing the driver from stepping on the accelerator by mistake in an emergency.

The Chinese patent with application number 200620060488.8 introduces an anti-explosion and anti-collision system for automobiles, which includes a signal transmitting module, a signal receiving module, an obstacle detection module and an audible and visual alarm module. Reminding the driver is far from enough. The subjective factors of the driver can also cause traffic accidents, so the anti-collision effect is not obvious, and it will cause the driver to panic and step on the accelerator by mistake.

The Chinese patent application number 200810079317.3 proposes a chaotic laser radar vehicle collision avoidance system and its method. The patent uses the chaotic laser light generated by the optical feedback semiconductor laser as the laser radar signal, and uses an audible and visual alarm to remind the driver. Due to the large subjective factors of the driver, it is easy to step on the accelerator by mistake in a panic situation, and it is impossible to eliminate the human subjective factors to avoid accidents.
