The invention discloses a time interval adjusting method and system, a state machine and a storage medium. The method comprises the steps that the speed of a front vehicle, the distance difference between the front vehicle and a current vehicle, the distance variation, the relative speed and the distance intrusion amount sent by an acquisition device are received; outputting a front vehicle low-speed working condition starting prohibition flag bit according to the distance difference and the front vehicle speed; the target speed of the current vehicle is determined according to the front vehicle low-speed working condition starting prohibition flag bit; according to the front vehicle speed, the distance variation, the relative vehicle speed and the distance intrusion amount, a longitudinal vehicle following state flag bit is output; determining a speed difference according to the target speed and the current speed of the current vehicle; determining a target time interval gear position flag bit according to the speed difference and the longitudinal car following state flag bit; and the time distance between the current vehicle and the front vehicle is adjusted according to the target time distance gear position flag bit. According to the scheme, the time interval is adjusted by outputting the multiple zone bits, the vehicle speed distance and other information according to the state machine, and the timeliness and accuracy of time interval adjustment can be improved.
本申请公开了一种调节时距的方法、系统、状态机及存储介质。该方法包括:接收采集装置发送的前车车速,以及前车与当前车辆的距离差、距离变化量、相对车速和距离侵入量;根据距离差和前车车速输出前车低速工况禁止起步标志位;根据前车低速工况禁止起步标志位确定当前车辆的目标车速;根据前车车速、距离变化量、相对车速和距离侵入量,输出纵向跟车状态标志位;根据当前车辆的目标车速和当前车速确定速度差;根据速度差和纵向跟车状态标志位确定目标时距挡位置位标志位;根据目标时距挡位置位标志位调节当前车辆与前车的时距。本申请方案通过根据状态机输出多个标志位以及车辆速度距离等信息来调节时距,可以提高对时距调节的及时性和准确度。
