Problems solved by technology

To a certain extent, it can reduce the occurrence of accidents, but it cannot fundamentally solve the problem that when the driver encounters an emergency, he mistakenly steps on the accelerator instead of the brake.

Embodiment 1

[0019] The acceleration sensor 1 is set on the accelerator pedal, the gear sensor 2 is set on the gear position of the motor vehicle or the car gearbox, the electronic throttle output signal switch 4 is set on the car electronic throttle output signal line, and the electronic brake system 5 is the brake system of the car itself , a signal processing unit MCU3 and a voice prompt unit 6 are set in the automobile control room, and the signal processing unit MCU3 is respectively arranged with the acceleration sensor 1, the gear sensor 2, the electronic throttle output signal switch 4, the electronic brake system 5, and the voice prompt unit 6. wire.

Embodiment 2

[0021] The acceleration sensor 1 on the accelerator pedal is used to monitor the acceleration of the driver stepping on the accelerator, and the gear sensor 2 is used to monitor the gear position of the driving vehicle when the driver steps on the accelerator. When the driver steps on the accelerator, the acceleration sensor 1 collects The acceleration signal and the gear position signal collected by the gear position sensor 2 are transmitted to the signal processing unit MCU3 at the same time, and the acceleration threshold value when the vehicle is running forward is set in the signal processing unit MCU3, and the acceleration threshold value is b2 when the vehicle is in reverse. , when the vehicle is running forward or in reverse, the signal processing unit MCU3 compares the acceleration signal and the gear position signal with the set acceleration threshold, judges whether the electronic throttle output circuit control switch 4 cuts off the output of the electronic throttle ...

Embodiment 3

[0023] When the vehicle is running forward, the acceleration threshold b1 is set in the signal processing unit MCU3 according to the acceleration signal of the acceleration sensor 1 and the gear position signal of the gear position sensor 2;

[0024] When the acceleration signal of the acceleration sensor 1 collected by the signal processing unit MCU3 does not match the gear position signal of the gear sensor 2, the signal processing unit MCU3 transmits a prompt signal to the voice prompt unit 6, and the voice prompt unit 6 prompts that the accelerator pedal is stepped on by mistake, please release accelerator;

[0025] When the acceleration signal of the acceleration sensor 1 collected by the signal processing unit MCU3 matches the gear position signal of the gear position sensor 2, and the accelerator acceleration is much smaller than the acceleration threshold b1 of the signal processing unit MCU3, the vehicle accelerates normally; the accelerator acceleration is close to th...

Abstract

Provided is an operation method for a safe control system for considering an accelerator as a brake under emergency circumstances of a motor vehicle. When a driver steps on the accelerator, an acceleration signal acquired by an acceleration sensor 1 and a gear position signal acquired by a gear position sensor 2 are transmitted to a signal processing unit MCU3 synchronously. When a vehicle runs forward or backs up, the signal processing unit MCU3 compares the acceleration signal and the gear position signal with a set acceleration threshold value, to determine whether a control switch 4 of an electronic throttle output circuit cuts off output of electronic throttle signals, and meanwhile the signal processing unit MCU3 sends a braking system starting / shutting down signal to an electronic braking system 5. Cooperating with other accident prevention measures of a vehicle, the method can effectively prevent occurrence of various fatal traffic accidents caused by considering an accelerator as a brake when a driver is a beginner, in emergency circumstances, in fatigue driving or peccancy driving after drinking.

Description

technical field [0001] The invention relates to the technical field of automobile active safety control, in particular to an operation method of an accelerator-variable-brake safety control system in an emergency situation of a motor vehicle. Background technique [0002] In recent years, with the sustained and rapid growth of our country's economy, the income of citizens has continued to increase, deposits have increased, and the price of cars has continued to decline. More and more people can afford cars. Cars have gradually become a very common means of transportation and have entered thousands of homes in China. Ten thousand households. Thereupon there are more and more people learning to drive a car, and many people drive on the road as soon as they get their driver's license. Due to the unskilled driving skills of novices, it is easy to step on the accelerator as a brake, causing vehicle collisions, casualties and other traffic accidents. Even old drivers may use the...
