The invention discloses a hybrid electric vehicle and a driving control method of the hybrid electric vehicle, which can switch driving modes more quickly and execute kick-down shift. In particular, a control method of a hybrid electric vehicle includes: when switching of a driving mode from an electric vehicle (EV) mode to a hybrid electric vehicle (HEV) mode and a kick-down shift is required at the same time, switching of the driving mode from the EV mode to the HEV mode is performed; determining available torques for target gears of a first motor directly connected to the engine and a second motor connected to the first motor in the HEV mode; and determining operation points of the first motor and the second motor before the end of the actual shift based on each determined available torque and the type of the kick-down shift.

    本发明公开一种能够更快速地切换驾驶模式并执行强制降挡变速的混合动力电动车辆及混合动力电动车辆的驾驶控制方法。特别地,混合动力电动车辆的控制方法包括:当同时需要将驾驶模式从电动车辆(EV)模式切换到混合动力电动车辆(HEV)模式以及强制降挡变速时,确定直接连接到发动机的第一马达和在HEV模式下连接到第一马达的第二马达的目标挡位的各可用扭矩;以及基于确定的各可用扭矩和强制降挡变速的类型,在实际变速结束前确定第一马达和第二马达的操作点。
