Problems solved by technology

[0002] In the existing technology, the vehicle can realize simple cruise control or simple adaptive cruise function through various sensors such as radar, camera and high-precision map under the condition of unmanned driving, but no obstacles can appear in the lane Carry out effective avoidance at times, without a relatively effective control strategy, driving safety cannot be guaranteed

Embodiment Construction

[0055] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0056] An embodiment of the present disclosure provides a vehicle adaptive cruise control method, such as figure 1 As shown, the method may include step S101 and step S102.

[0057] In step S101, it is detected whether there is an obstacle in front of the vehicle.

[0058] Wherein, the method for detecting obstacles may be to detect a certain distance in front of the vehicle through laser radar and / or millimeter wave radar.

[0059] In step S102, when an obstacle is detected in front of the vehicle, according to the distance between the obstacle and the vehicle, the sum of the absolute difference between the moving speed of the obstacle and the predetermine...

Abstract

The invention provides a self-adaptive cruise control method and device of a vehicle, and the vehicle, and relates to the field of vehicles. The method comprises the following steps: detecting whether an obstacle exists in front of the vehicle; when the obstacle is detected in front of the vehicle, controlling self-adaptive cruise control of the vehicle according to the distance between the obstacle and the vehicle, the absolute difference between the moving speed of the obstacle and a preset vehicle speed of the vehicle and the closet distance between the obstacle and the lane line of a lane where the vehicle is. Therefore, an effective control strategy is provided for the self-adaptive cruise control of the vehicle, so that the traffic safety is guaranteed to a certain extent.

Description

technical field [0001] The present disclosure relates to the vehicle field, in particular, to a vehicle adaptive cruise control method, device and vehicle. Background technique [0002] In the existing technology, the vehicle can realize simple cruise control or simple adaptive cruise function through various sensors such as radar, camera and high-precision map under the condition of unmanned driving, but no obstacles can appear in the lane Carry out effective avoidance at times, without a relatively effective control strategy, driving safety cannot be guaranteed. Contents of the invention [0003] The purpose of this disclosure is to provide a vehicle adaptive cruise control method, device and vehicle, which provides an effective control strategy for the situation that the vehicle encounters obstacles during adaptive cruise, and ensures driving safety to a certain extent . [0004] In order to achieve the above purpose, the present disclosure provides a vehicle adaptive...
