Embodiment 1

[0019] The acceleration sensor 1 is set on the accelerator pedal, the gear position sensor 2 is set on the gear of the motor vehicle or the gearbox of the automobile, the electronic throttle output signal switch 4 is set on the electronic throttle output signal line of the automobile, and the electronic brake system 5 is the braking system of the car itself , a signal processing unit MCU3 and a voice prompt unit 6 are set in the car control room, and the signal processing unit MCU3 is respectively set with the acceleration sensor 1, the gear position sensor 2, the electronic accelerator 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 pressing the accelerator, and the gear position sensor 2 is used to monitor the gear position of the driving vehicle when the driver steps on the accelerator. The acceleration signal of the vehicle and the gear signal collected by the gear sensor 2 are simultaneously transmitted to the signal processing unit MCU3. First, the acceleration threshold when the vehicle is driving forward is set as b1 in the signal processing unit MCU3, and the acceleration threshold when the vehicle is driving in reverse is b2. , When the vehicle is driving forward or in reverse, the signal processing unit MCU3 compares the acceleration signal with the set acceleration threshold and combines the gear signal, and outputs to the electronic accelerator output circuit control switch 4 whether to cut off the electronic accelerator output circuit control switch 4, and at the same time send a signal ...

Embodiment 3

[0023] When the vehicle is driving 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 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 signal of the gear position sensor 2, the signal processing unit MCU3 transmits a prompt signal to the voice prompt unit 6, and the voice prompt unit 6 prompts you to step on the wrong accelerator, please release accelerator;

[0025] When the acceleration signal of the acceleration sensor 1 collected by the signal processing unit MCU3 matches the gear 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 the signal processing unit. When t...

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 active safety control of automobiles, in particular to an operation method of a safety control system for changing the accelerator and braking under the emergency situation of a motor vehicle. Background technique [0002] In recent years, with the continuous and rapid growth of my country's economy, the income of citizens has continued to increase, their savings have increased, and the price of automobiles has continued to decline. More and more people can afford automobiles, and automobiles have gradually become an extremely common means of transportation. million households. Along with this, more and more people are learning to drive, and many people are driving on the road as soon as they get their driver's license. Because novice driving skills are not proficient, it is easy to use the accelerator as a brake pedal, causing traffic accidents such as vehicle collisions and casualties. Even older drive...
