A method and device for automatically cutting off fuel and turning the accelerator into a brake when the vehicle is overspeed

Abstract

A method automatically cutting off oil and turning an accelerator into a brake in case of automobile speeding is characterized in that a speed sensor is installed beside an automotive speedometer and is capable of sending out an electrical signal command to switch on an oil circuit solenoid valve when the speed of an automobile exceeds a set value and cutting off an oil supply circuit for the automobile through the oil circuit solenoid valve so as to disable oil supply even after an accelerator pedal is stepped; while the oil supply circuit for the automobile is cut off, a brake trigger switch below the accelerator pedal is switched on; if a driver still steps the accelerator pedal, the brake trigger switch is started to turn the accelerator pedal into a brake pedal and the automobile is braked through the brake trigger switch; a deep emergency brake trigger switch is further disposed below the brake trigger switch below the accelerator pedal; when the brake trigger switch malfunctions and the driver quickly steps the accelerator pedal deep to a deep emergency brake switch triggering position, the deep emergency brake trigger switch is started to automatically cut off the oil supply circuit and brake the automobile.

Description

technical field [0001] The present invention relates to a control method and device for a car, in particular to a method and device for automatically cutting off the gas pedal and changing the gas pedal to a brake pedal when the car exceeds a set running speed, and can also use the gas pedal as a brake pedal by mistake. The invention discloses a method and device for controlling the speed of an automobile, which changes the accelerator into a brake when the accelerator is stepped on sharply, and belongs to the technical field of automobiles. Background technique [0002] Since the beginning of the new century, China's automobile production and sales have shown a blowout trend of accelerated growth. In 2005 alone, the country only sold 5.76 million new cars, which almost quadrupled in just 5 years. In 2010, the sales volume reached 18.06 million, making it the largest car market in the world and the number one in the world. Great new car market. According to the forecast of...

Problems solved by technology

[0007] Although the above-mentioned patents have improved from the gas pedal to the brake, they do not limit the refueling when overspeeding, so the overspeeding phenomenon is still prone to occur on the expressway, and further improvement is required.
