Abstract

The invention belongs to the technical field of automobile intelligent driving assistance, and relates to a slope speed precise control method for a vehicle-mounted intelligent cruise system. The cruise vehicle speed regulation is responsible for cruise vehicle speed regulation by a cruise vehicle speed regulation control module, the cruise vehicle speed regulation control module collects input information, and after comprehensive decision judgment, cruise vehicle speed regulation related control information is output, so that cruise vehicle speed self-adaptive regulation control is realized; the input information means that four paths of information are input at the same time, and each path of input information representing one type of information is the current basic state of the vehicle, cruise setting information, current driving state information of the vehicle and sensor acquisition information; inputting the fifth path of information; the input 5 is'navigation map information input '; according to the invention, the accuracy of cruise speed control when the vehicle runs on a high-rise fluctuating slope is improved; and the comfort feeling of passengers in the vehicle is considered, so that the cruise vehicle speed control adjustment is highly consistent with the cruise vehicle speed set by a driver, and the driving feeling of the driver is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automobile intelligent driving assistance, and relates to a method for accurately controlling vehicle speed on slopes in a vehicle-mounted intelligent cruise system. Background technique [0002] With the improvement of automobile intelligence, the application of advanced driver assistance (ADAS) is gradually increasing, such as adaptive cruise system, automatic emergency braking system, lane keeping system and so on. The application of these advanced driver assistance systems reduces the driver's driving burden on the one hand, and on the other hand greatly improves the safety of vehicle driving. [0003] Among driving assistance systems, cruise assist assists the driver while driving. At present, in the automotive industry, the mainstream cruise systems include: constant speed cruise system, adaptive cruise system, and intelligent cruise system. [0004] The cruise control system means that after the ...
