Embodiment Construction

[0040] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0041] In real life, when driving on urban roads, you often encounter traffic congestion. Adaptive cruise control can automatically start and stop the vehicle according to the start and stop of the vehicle in front. The driver needs to be reminded by means of an alarm. If the driver does not respond in time or operates incorrectly, collisions or scrapes are likely to occur. Therefore, the embodiment of the present invention proposes a safe driving method for vehicles based on this forced lane change.

[0042] The following descri...

Abstract

The invention discloses a vehicle and a safe driving method and device for the vehicle. The first vehicle runs in an automatic cruise mode, and the method includes the following steps: controlling the first vehicle to detect whether a second vehicle in an adjacent lane is changing lanes ; When detecting that the second vehicle is changing lanes, the control obtains the minimum inter-vehicle distance between the second vehicle and the first vehicle in the target direction; wherein, the target direction is a direction perpendicular to the direction of travel of the first vehicle; according to the minimum inter-vehicle distance, Identifying whether there is a driving risk between the second vehicle and the first vehicle; if there is a driving risk, performing deceleration control on the first vehicle so that the second vehicle completes the lane change. The method can control the deceleration of the vehicle when the vehicle has a driving risk, avoiding the collision or friction of the vehicle, improving the safety of the vehicle and the safety of users.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle and a safe driving method and device for the vehicle. Background technique [0002] With the development of vehicle intelligence, more and more driving assistance functions are applied to vehicles. For example, during vehicle driving, there are generally adaptive cruise control (Adaptive Cruise Control, ACC for short), lane departure warning ( Lane Keeping Aid, referred to as LKA), blind spot detection (Blind Spot Detection, referred to as BSD) and other auxiliary functions; in the process of vehicle reversing, there are generally Rear and Side Detection System, referred to as RSDS), automatic parking assistance system (Auto Parking Assist, referred to as APA) and other reversing assistance functions. At present, ACC has been able to realize the automatic start and stop function of the vehicle. [0003] However, in traffic jams, if a vehicle in an adjacent lane is fo...
