Driving safety control device related to pavement adhesion coefficient

Abstract

The invention provides a driving safety control device related to a pavement adhesion coefficient, which belongs to the technical field of automobile driving safety and solves the problem that: the conventional automobile cannot make deceleration response timely due to sudden deterioration of the surface condition during driving. The driving safety control device related to the pavement adhesion coefficient comprises a pavement adhesion coefficient detection device connected with an automobile deceleration mechanism; and the detection device is used for detecting the magnitude of the pavement adhesion coefficient, and the speed of an automobile is reduced through the automobile deceleration mechanism when the detection device detects that the reduction amplitude of the pavement adhesion coefficient is large. The driving safety control device related to the pavement adhesion coefficient has the advantages that: through the driving safety control device, the speed of the automobile can be automatically reduced according to an automatic control principle when the pavement adhesion suddenly deteriorates so as to guarantee the driving safety of the automobile on a low-adhesion pavement. Only a simple module is added into the conventional vehicle stability control system so as to form the system, the driving safety control device has huge benefit and a good market application prospect, and is easy to implement.

Description

A driving safety control device about road surface adhesion coefficient technical field The invention belongs to the technical field of automobile driving safety, and relates to a driving safety control device related to road surface adhesion coefficient. Background technique The road surface adhesion coefficient is the ratio of the adhesion force to the normal (perpendicular to the road surface) pressure of the wheel. It can be regarded as the static friction coefficient between the tire and the road surface. The larger the coefficient, the greater the available adhesion and the less likely the car will skid. The size of the adhesion coefficient mainly depends on the type and dryness of the road surface, and is related to the structure of the tire, the tread pattern and the driving speed. Generally speaking, dry and good asphalt or concrete roads have the largest adhesion coefficient, up to 0.7 to 0.8, making the car not easy to slip and driving safely; while ice and sn...
