Problems solved by technology

However, the current advanced driver assistance system is limited by the detection distance of the sensor, so it is difficult to detect the information of the relative position of the ramp exit in front of the road
This limitation makes it more difficult to develop a safer and more reliable on-ramp automatic switch driving assistance function

Abstract

The invention relates to a high-speed function automatic switching system. The high-speed function automatic switching system enables a host vehicle to enter and exit ramps of highways automatically and change lanes. The system comprises a vehicle positioning module, a signal processing module, and a switch prompt module, wherein the vehicle positioning module is configured to position the host vehicle, calculate a longitudinal road distance between the host vehicle and entrance and exist of a ramp of the highway, and acquire information of a lane in which the host vehicle is and lane information of a target lane, the information processing module is configured to determine whether the host vehicle arrives at or is at a prompt area of the entrance and exit of the ramp of the highway according to information determined by the vehicle positioning module and speed of the host vehicle, distance information and speed information of the host vehicle and surrounding vehicles, and the switch prompt module is configured to give out a switch prompt signal when determining that the host vehicle arrives at or is at the prompt area of the entrance and exit of the ramp of the highway.

Description

technical field [0001] The present invention relates to advanced driving assistance functions of vehicles, in particular to an advanced driving assistance method for automatically switching ramps when a vehicle is running on an expressway, a high-speed function automatic switching system for implementing the process of automatically switching ramps, and an advanced driving assistance system. Background technique [0002] In recent years, with the continuous development of artificial intelligence technology, the development of driver assistance functions has played an increasingly important role in the field of automotive research and development. Here, many high-end models are equipped with increasingly sophisticated advanced driver assistance functions. Among the many advanced driving assistance functions, the ability to assist the vehicle to realize automatic switching of ramps on the expressway can greatly reduce the driver's driving burden on the expressway, and at the s...
