The invention relates to a hybrid electric vehicle and a method for controlling speed limit for same. The method includes determining a virtual vehicle speed as being a lower one of a vehicle speed and a target limit speed, determining a virtual APS value as being a larger one of a first APS value and a second APS value, transitioning to a second mode at a point in time at which an actual APS value and the second APS value become different, when it is expected to transition to the second mode, among a first mode for sustaining a SOC of a battery at the target limit speed and the second mode for depleting the SOC, and determining a transmission gear position by applying the determined virtual vehicle speed and the determined virtual APS value to one of a first shifting pattern and a second shifting pattern.
本公开涉及一种混合动力车辆及其控制限速的方法,该方法包括:将车速和目标限速中的较小值确定为虚拟车速;将第一APS值和第二APS值中的较大值确定为虚拟APS值;当期望在目标限速下维持电池的SOC的第一模式和耗尽SOC的第二模式中转换为第二模式时,在实际APS值和第二APS值变得不相同的时间点转换为第二模式;以及通过将所确定的虚拟车速和所确定的虚拟APS值应用于第一变速模式和第二变速模式中的一个,来确定变速器挡位。
