Abstract

The invention discloses a navigation-based adaptive cruise method. The method comprises the steps of acquiring radar acquisition information in front of a vehicle, and judging whether a target vehicle exists in front or not; if the target vehicle does not exist, entering a constant-speed cruise mode, acquiring vehicle-mounted navigation information in real time, and adjusting a first cruise speed according to the vehicle-mounted navigation information and a preset cruise speed; if the target vehicle exists, entering an adaptive cruise vehicle following mode, acquiring vehicle-mounted navigation information and the target speed in real time, adjusting a second cruise speed according to the vehicle-mounted navigation information and the target speed, exiting the adaptive cruise vehicle following mode when the target vehicle suddenly disappears, judging the road condition according to the vehicle-mounted navigation information, and entering a constant-speed cruise mode or uniformly decelerating and parking. The speed adjusting strategy is adopted according to the conditions that the road speed limit changes and the front target vehicle overspeeds and disappears in the adaptive cruise mode, and the safety risks such as sudden acceleration caused by overspeed and misjudgment of the vehicle are avoided.

Description

technical field [0001] The invention relates to the technical field of adaptive cruising, in particular to a navigation-based adaptive cruising method. Background technique [0002] In order to alleviate driving fatigue, the adaptive cruise function can automatically control the vehicle to drive at a preset speed or maintain a preset safe following distance from the vehicle in front, which can reduce driving fatigue during long-distance driving. However, there are different maximum speed limits or interval speed limits in actual roads. If the driver sets or adjusts the cruise speed, it is necessary to cancel and set the cruise control frequently, which affects the driving experience. , Adaptive cruise is prone to misjudgment. Contents of the invention [0003] The invention provides a navigation-based adaptive cruising method. By identifying whether there is a target vehicle in front, the constant-speed cruising or adaptive cruising mode is selected, and the vehicle speed...
