Emergency braking device capable of automatically changing motor vehicle tire pressure and method thereof

Abstract

An emergency braking device capable of automatically changing the motor vehicle tire pressure comprises a microprocessor connected with an LCD, wherein the microprocessor is connected with a speed sensor; a displacement sensor mounted on a brake pedal is connected with the microprocessor; the microprocessor is connected with a wireless transmitter through a wireless receiver; the wireless transmitter is connected with a tire pressure detection device arranged on a wheel hub; the control terminal of the microprocessor is connected with an electromagnetic valve through a tire control device; the wireless receiver is connected with the signal receiving end of the microcontroller. The microprocessor is used for judging whether the emergency braking is performed according to a received signal being 1 or 0, the tire control device is used for sending out the command of reducing the tire pressure to the electromagnetic valve simultaneously, the tire pressure of rear two tires is reduced firstly, and then the tire pressure of the front two tires is reduced, so that a vehicle can slow down and stop steadily and quickly; the emergency braking device has the characteristics of quick braking and excellent braking effect.

Description

technical field [0001] The invention relates to the technical field of automobile emergency braking, in particular to an emergency braking device and method for automatically changing the tire pressure of a motor vehicle. Background technique [0002] With the development of automobile braking technology, rapid braking of automobiles is of great significance to reduce traffic accidents. The general principle of the braking system is to use the mutual friction between the non-rotating elements connected to the body and the rotating elements connected to the wheels to prevent the rotation of the wheels. When the car encounters an emergency and the speed is high, it cannot stop quickly, which will cause the car to rear-end or even rush out of the road, which will bring serious harm to people's lives and property. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide an emer...
