The invention relates to the technical field of vehicles, in particular to a vehicle following time interval verification method and device, a vehicle and a storage medium, and the method comprises the steps: obtaining the driving state information and perception information of a current vehicle; calculating the minimum safe vehicle following distance of the current vehicle according to the driving state information, determining the target vehicle following time interval of the current vehicle according to the current driving scene matched with the sensing information and the driving state information, and judging whether the minimum safe vehicle following distance is smaller than the target vehicle following time interval or not; and if the minimum safe car-following distance is smaller than the target car-following time interval, it is judged that the target car-following time interval verification is passed, otherwise, it is judged that the target car-following time interval verification fails, and a corresponding improvement suggestion is generated after the verification fails. Therefore, the problems that in the prior art, the minimum safety distance is not required, and longitudinal control is unreasonable are solved, the reasonability of longitudinal control is improved, and the verification module can ensure the safety of the vehicle under the condition that the main controller fails.

    本申请涉及车辆技术领域,特别涉及一种车辆的跟车时距校验方法、装置、车辆及存储介质,其中,方法包括:获取当前车辆的行驶状态信息和感知信息;根据行驶状态信息计算当前车辆的最小安全跟车距离,且由感知信息匹配的当前驾驶场景和行驶状态信息确定当前车辆的目标跟车时距,并判断最小安全跟车距离是否小于目标跟车时距;以及若最小安全跟车距离小于目标跟车时距,则判定目标跟车时距校验通过,否则,判定目标跟车时距校验失败,并在校验失败后生成对应的改进建议。由此,解决了相关技术未对最小安全距离作出要求,纵向控制的不合理的问题,增加纵向控制的合理性,校验模块能够在主控制器失效的情况下确保车辆的安全。
