Vehicle Steering Target Transition for Preceding Vehicle Switching

The patent applies dynamics by making the control target point movable and adjustable during the transition period. The control target point is dynamically shifted from the pre-switching preceding vehicle to the post-switching preceding vehicle over time, allowing the system to adapt its tracking behavior continuously rather than making abrupt changes. This dynamic adjustment resolves the contradiction by enabling both responsiveness (through eventual target switching) and stability (through gradual transition).

The patent introduces an intermediary mechanism - the control target point - that mediates between the pre-switching and post-switching preceding vehicles. Instead of directly switching from one vehicle to another, the control target point serves as an intermediate reference that gradually transitions its position. This intermediary approach allows for smooth steering adjustments while maintaining continuous tracking, resolving the instability caused by direct target switching.

The patent applies preliminary action by preparing for the target switch in advance. Before completely switching to the post-switching preceding vehicle, the control target point is gradually shifted toward the new target over a predetermined period. This preliminary transition allows the steering system to adapt progressively, maintaining predictability and reliability while still achieving accurate tracking of the new vehicle ultimately.

The patent utilizes parameter changes by modifying the control target point's position parameters over time. The control target point's coordinates are continuously adjusted from the pre-switching vehicle's position to the post-switching vehicle's position. This gradual parameter transition ensures that steering control remains predictable and reliable while still achieving accurate tracking of the new target vehicle.

The patent applies dynamics by implementing a time-varying control target point that adapts to new traffic conditions while maintaining stability. The control target point dynamically transitions from the pre-switching preceding vehicle to the post-switching preceding vehicle over a predetermined period. This dynamic approach allows the vehicle to adapt to changing traffic conditions (high adaptability) while avoiding sudden steering changes that would cause instability.

The patent applies beforehand cushioning by preparing for the transition to the new preceding vehicle in advance. The control target point is gradually shifted toward the new target before the complete switch occurs, cushioning the transition and preventing sudden steering direction changes. This cushioning effect maintains vehicle behavior stability while still enabling timely adaptation to new traffic conditions.
