The invention discloses a collision early warning method based on a vehicle-mounted ad hoc network, a vehicle-mounted terminal and a vehicle. The collision early warning method comprises the following steps: receiving alarm information/alarm release information sent by other vehicles through a mobile communication private network; analyzing the received alarm information/alarm release information, determining whether danger alarm/alarm release is performed or not according to an analysis result, and forwarding the alarm information/alarm release information after order-time coding and order increasing in the alarm information/alarm release information; and when it is determined that danger alarm/alarm release is carried out according to the analysis result, danger alarm/alarm release is carried out. According to the invention, the accident vehicle can actively issue alarm information to remind the subsequent vehicle to take measures in advance, so that the collision risk of the subsequent vehicle is reduced; the method is slightly influenced by the environment and is wide in application range; the accuracy of sending and receiving the alarm information/alarm release information is high; after the accident is handled, the alarm can be removed in time.

    本发明公开一种基于车载自组织网络的碰撞预警方法、车载终端及车辆,包括:通过移动通信专网接收其他车辆发送的告警信息/告警解除信息;解析接收到的告警信息/告警解除信息,根据解析结果确定是否进行危险告警/告警解除,对告警信息/告警解除信息中的序时编码增序后转发告警信息/告警解除信息;当根据解析结果确定进行危险告警/告警解除时进行危险告警/告警解除。本发明中事故车辆可主动发布告警信息,提醒后续车辆提前采取措施,降低后续车辆的碰撞风险;本发明受环境影响小,适用范围广;告警信息/告警解除信息发送和接收的精准性高;事故处理完毕后,可及时解除告警。
