System and method for improving adhesion coefficient of tire to pavement

Abstract

The invention discloses a system for improving the adhesion coefficient of a tire to a pavement, which comprises a tire wet and dry state identification module, an inertial navigator vehicle speed sensor, a wheel speed sensor, a microprocessor and an anti-skid spraying device. The output end of the inertial navigator speed sensor, the output end of the wheel speed sensor and the output end of thetire wet and dry state identification module are respectively connected with the input end of the microprocessor; and the output end of the microprocessor is connected with the control end of the anti-skid spraying device. A method for improving the adhesion coefficient of a tire to a pavement is also disclosed. According to the adhesion state of the vehicle tire to the pavement and the dry and wet state of the tire, the adhesion coefficient of the tire to the pavement can be increased temporarily by spraying the anti-skid powder or the anti-skid agent to the contact position of the tire to the pavement, which can improve the climbing ability of the vehicle, shorten the braking distance of the vehicle and improve the driving safety of the vehicle under the emergency and necessary conditions.

Description

technical field [0001] The invention relates to the technical field of automobile driving safety, in particular to a system and method for improving the adhesion coefficient between tires and road surfaces. Background technique [0002] A good road surface adhesion coefficient is an important guarantee for the car to run normally on the road surface. If the road surface adhesion coefficient is insufficient, especially when it is raining, icy and snowy, or on a slope with a large slope, the car will often slip or slip. Insufficient coefficients will have a great impact on vehicle driving safety and dynamic performance. [0003] In order to increase the braking force and shorten the braking distance, some people propose to install a deceleration parachute at the rear of the vehicle to increase the air resistance, but the deceleration parachute may interfere with the vehicles behind; When it is small, emergency braking may also cause slippage. Because the speed of the vehicle ...

[0003] In order to increase the braking force and shorten the braking distance, some people propose to install a deceleration parachute at the rear of the vehicle to increase the air resistance, but the deceleration parachute may interfere with the vehicles behind; When it is small, emergency braking may also cause slippage. Because the vehicle speed is small, the effect of the parachute is very weak.
