Problems solved by technology

At present, most of the models equipped with Advanced Driver Assistance System (ADAS) function in various OEMs have a single-lane instrument display, but the single-lane display cannot display the potential following targets in front of the vehicle, and cannot remind the driver of the current state of the vehicle ahead and possible driving trend

Abstract

The invention relates to the technical field of intelligent driving, and discloses a self-adaptive cruising method. The method comprises the steps that the driving state information of a vehicle and the information of the surrounding driving environment of the vehicle are collected in real time; the obtained real-time information is processed, and according to the processing result, a self-adaptive cruising system enters a corresponding self-adaptive cruising state; according to the current state of the self-adaptive cruising system, a target vehicle is determined, and the target vehicle is displayed on a vehicle-mounted display device. The invention further discloses the self-adaptive cruising system. The system comprises a real-time information collection module, a real-time data processing module and a target vehicle display module. By means of the self-adaptive cruising method and system, the display information of the target vehicle can be provided for a driver in different statesof the self-adaptive cruising system so that the driver can better know the surrounding driving environment and can know the current state of the system in real time, and it is convenient for the driver to better use the self-adaptive cruising function.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving, in particular to an adaptive cruise method and system. Background technique [0002] Adaptive Cruise Control (ACC) is an intelligent automatic control system, which belongs to the active safety technology, and it is developed on the basis of the existing cruise control technology. The function of the adaptive cruise system is based on the traditional constant speed cruise, using radar to detect the relative distance and relative speed between the vehicle in front and the own vehicle, and actively controlling the driving speed of the own vehicle, so as to achieve the purpose of automatic follow-up cruise. Depending on whether there is a car ahead, the system can automatically switch between constant speed cruise and follow-up cruise. [0003] During the driving process of the vehicle, the vehicle distance sensor installed in the front of the vehicle continuously scans the road...
