The invention belongs to the technical field of automobiles, and particularly relates to a cooperative control method for inter-queue spacing of a two-factor automobile queue. The cooperative control method comprises the following steps: a rear vehicle uses a two-factor feedback distance controller to control the distance in a queue; the preceding vehicle uses a cooperative spacing controller to control the inter-queue spacing. Compared with traditional single-factor queue spacing control, the method has multiple advantages in the aspects of queue cooperative control and stability, spacing control is conducted by comprehensively considering the difference between the actual queue spacing and the expected spacing and the difference between the queue vehicle speeds, the following vehicle can slow down the approaching intensity when the main vehicle slows down, and sudden braking is avoided; and meanwhile, when the rear vehicle falls farther, the main vehicle actively decelerates and waits for approaching, so that the queue spacing can be constructed and maintained more quickly.
本发明属于汽车技术领域,具体的说是一种双因素汽车队列队内间距协同性控制方法。该协同性控制方法包括:后车使用双因素反馈间距控制器对队内间距进行控制;前车使用协同性间距控制器对队内间距进行控制。本发明在队列协同控制与稳定性方面相较于传统单因素队列间距控制有若干优势,通过综合考虑队列实际间距与期望间距之差与队列车辆速度之差进行间距控制,使得后车能够在主车减速时放缓追近强度,避免急刹;同时,当后车落后较远时,主车将主动减速等待其追近,可以更加快速的构建与维持队列间距。
