The invention discloses a TTC prompting system based on dynamic tactile interaction, and the system comprises an environment perception module which collects the dynamic information of surrounding traffic participating vehicles in real time; the collision prediction module is used for receiving the dynamic information, predicting time to collision (TTC) according to the dynamic information and the motion state of the vehicle, and generating collision early warning information according to a TTC value; the dynamic touch early warning module comprises a plurality of vibration units, and the plurality of vibration units respectively correspond to different directions; and the dynamic touch early warning module receives the collision early warning information and activates the vibration unit in the corresponding direction according to the direction of the collision risk corresponding to the collision early warning information, so that the vibration unit generates vibration. The invention further discloses a TTC prompting method based on dynamic tactile interaction, a more intuitive and efficient collision early warning mode is provided, it is ensured that a driver can obtain a warning with the best space perception in the shortest time, the response time of the driver is optimized, and the road safety is improved.

    本发明公开了一种基于动态触觉交互的TTC提示系统,包括:环境感知模块,其实时采集周围交通参与车辆的动态信息;碰撞预测模块,其接收所述动态信息,并根据动态信息及自车的运动状态预测碰撞时间(Time to Collision,TTC),根据TTC值生成碰撞预警信息;动态触觉预警模块,其包括多个振动单元,多个振动单元分别对应不同的方位;动态触觉预警模块接收所述碰撞预警信息,并根据所述碰撞预警信息对应的碰撞风险所在的方位激活对应方位的振动单元,使振动单元产生振动。本发明还公开了一种基于动态触觉交互的TTC提示方法,提供了一种更加直观和高效的碰撞预警方式,确保驾驶员能够在最短时间内获得最具空间感知的警示,优化驾驶员的反应时间,提高道路安全性。
