Description

Technical Field

[0001] The present invention relates to the technical field of intelligent driving, and in particular to an overtaking assistance control method, device, equipment, storage medium and vehicle for intelligent driving. Background Art

[0002] As vehicles become more intelligent, intelligent driving systems play an increasingly important role in vehicle control. ADAS (Advanced Driving Assistance System) controls the vehicle's acceleration, braking, and steering. Under normal circumstances, the driver does not need to directly control the vehicle, but only needs to monitor its driving status. ADAS, equipped with environmental perception sensors such as front cameras and radar, can implement adaptive cruise control. This function detects the speed and distance of the preceding vehicle and, based on the vehicle's own speed and a set time gap, maintains a certain distance from the preceding vehicle. The overtaking assist function within ADAS allows the driver to observe the adjacent lane and confirm that the preceding vehicle is suitable for overtaking. If the driver activates the turn signal while the preceding vehicle is accelerating, the system automatically controls the vehicle's longitudinal direction to accelerate and overtake.

[0003] Currently, the overtaking assistance function in ADAS has the following problems: First, during the longitudinal control acceleration overtaking process, due to the limitation of TTC (Time To Collision), the vehicle cannot accelerate before releasing the target vehicle in the lane. The vehicle's speed cannot be accelerated until the front wheels of the vehicle enter the overtaking lane. This does not conform to the driver's driving habits and the subjective overtaking experience is poor. Second, when the target vehicle in front of the lane suddenly decelerates, the vehicle will also decelerate sharply. If the driver uses the turn signal to change lanes at this time, the target vehicle in front of the lane releases the signal later, causing the vehicle to continue decelerating even when it is in the overtaking lane, resulting in a delayed acceleration feeling for the user and a poor overtaking experience. Summary of the Invention
