The embodiment of the invention provides a lane changing decision information generation method and device, electronic equipment and a storage medium. The method comprises the steps of determining a quintic curve function of a target vehicle during lane changing according to lane changing start-stop state information of the target vehicle; according to a KKT condition principle and the vehicle stress information of the target vehicle, determining a yaw velocity extreme value corresponding to the target vehicle; based on the quintic curve function and the yaw velocity extreme value, determining a lane changing risk assessment coefficient corresponding to the target vehicle; and generating lane changing decision information of the target vehicle based on the lane changing risk assessment coefficient. According to the embodiment of the invention, a safety decision can be made for lane changing of the vehicle, and the situation that the vehicle laterally slides due to insufficient tire stress support in the lane changing process is avoided.
本申请实施例提供了一种变道决策信息生成方法、装置、电子设备及存储介质。所述方法包括:根据目标车辆的变道起止状态信息,确定所述目标车辆在变道时的五次曲线函数;根据KKT条件原理和所述目标车辆的车辆受力信息,确定所述目标车辆对应的横摆角速度极值;基于所述五次曲线函数和所述横摆角速度极值,确定所述目标车辆对应的变道风险评估系数;基于所述变道风险评估系数,生成所述目标车辆的变道决策信息。本申请实施例可以为车辆变道做出安全决策,避免在变道过程中轮胎受力支撑不够而使车辆发生侧向滑移的情况。
