Problems solved by technology

[0003] However, when the driver of the vehicle travels especially in winter, if the driver does not know whether there is a slippery section (such as a section covered by ice and snow) on the road ahead and chooses to go, it may cause the vehicle to enter the slippery section, thus causing the vehicle to slip. The phenomenon that the road surface is too slippery to be unable to move or even cause a traffic accident

Abstract

The invention relates to an auxiliary driving system and method. The auxiliary driving system comprises a cloud end service device and a car-mounted control device which can be in communication with each other. The cloud end service device is configured to calculate a road adhesion coefficient mean value of each of multiple road units in a preset time period according to a road adhesion coefficient sample from a car. The car-mounted control device is configured to provide a control signal for automatically executing control operation for the car according to the road adhesion coefficient meanvalue from the cloud end service device.

Description

Technical field [0001] The present invention generally relates to the field of driving assistance for vehicles, and more particularly to a driving assistance system and a driving assistance method capable of warning slippery road sections. Background technique [0002] It is known that the road adhesion coefficient (also regarded as the static friction coefficient between the tire and the road surface) determines whether the vehicle is prone to slipping during driving. In other words, the greater the adhesion coefficient of the road, the greater the adhesion of the tire to the road, and the less likely the vehicle will slip; on the contrary, the smaller the adhesion coefficient of the road, the smaller the adhesion of the tire to the road, and the more likely the vehicle will slip. . The pavement adhesion coefficient mainly depends on the type and dry condition of the road surface. Generally speaking, the adhesion coefficient of dry and good asphalt or concrete pavement is rela...
