Abstract

The invention discloses a vehicle following time interval adjusting method based on an ADAS map. The method comprises the following steps that the current vehicle speed of a vehicle is obtained, and the current road traffic flow information and the road type of the vehicle are obtained through the ADAS map; according to the current road traffic flow information, the road type and the current vehicle speed, the current driving state of the vehicle is judged, and the vehicle following time interval is adjusted in real time. According to the car following time interval adjusting method based on the ADAS map, the car following time interval can be automatically adjusted, and comfortable and safe driving experience is provided for a driver.

Description

technical field [0001] The invention relates to the technical field of vehicle driving, in particular to a method for adjusting the following time distance based on an ADAS map. Background technique [0002] With the rapid development of automatic driving assistance technology, automobile automatic driving assistance technology has been popularized from the cutting-edge technology to the lives of the public. From constant speed cruise to adaptive cruise and then to integrated adaptive cruise, the degree of intelligence of automobiles is getting higher and higher. , by assisting the driver to reduce frequent brakes and accelerators, the driver can reduce driver fatigue on long-distance or short-distance driving, making driving from a simple and boring mode of transportation to assisting the driver to make it easier and improve the quality of life necessities. [0003] However, currently there is no known adaptive cruise-related patented technology on the market that can auto...
