Auxiliary driving method, device and system

Abstract

The invention discloses an auxiliary driving method, device and system which are applied to a vehicle, and the vehicle comprises a vehicle control unit, a vehicle-mounted camera and a vehicle-mounted radar. The method comprises the following steps: acquiring road surface information through a vehicle-mounted camera; acquiring wheel sliding information and vehicle speed information through the vehicle control unit; determining a braking distance according to the road surface information, the vehicle sliding information and the vehicle speed information; acquiring the horizontal distance between the position of the current vehicle and the position of the traffic signal lamp through the vehicle-mounted radar; obtaining the state of the traffic signal lamp through the vehicle-mounted camera, and when the state of the traffic signal lamp is red, if the horizontal distance is larger than the braking distance and smaller than a first preset distance, sending a sound prompt signal and a visual prompt signal; the problem that a driver with color weakness cannot normally judge the traffic signal lamp can be effectively solved, and the distinguishing burden of the driver with color weakness does not need to be increased.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a driving assistance method, device and system. Background technique [0002] Traffic lights can play a role in safety guidance for vehicles on the road. Because traffic lights are divided into red lights and green lights, it is difficult for color-blind drivers to distinguish between red and green. Traffic lights are difficult to guide vehicles driven by color-blind drivers. [0003] For this reason, in the prior art, existing traffic lights are transformed. Add the word "X" to the red light of the traffic light, and add the word "-" to the green light to remind the color-blind driver of the color of the traffic light. [0004] However, there is a problem that the workload is relatively large to transform the existing traffic lights. In addition, the way of adding "X" and "-" to traffic lights also requires color-blind drivers to strengthen their memory. It increa...
