The invention discloses a hybrid electric vehicle capable of reducing an engine entering a full-load driving mode and an engine control method thereof. The method includes determining whether a depression degree of an accelerator pedal (APS) is equal to or greater than a reference value set as a condition for an engine to enter a full-load driving mode; determining a partial load torque corresponding to a maximum torque of the engine in the partial load driving mode and a motor torque corresponding to a maximum torque of the motor when the depression degree of the accelerator pedal is equal to or greater than a reference value; comparing a sum of the partial load torque and the motor torque to a driver required torque; and controlling the engine to be in a full-load driving mode or a partial-load driving mode according to a comparison result.

    本申请公开了一种能够减少发动机进入全负载驱动模式的混合动力电动车辆及其发动机控制方法。该方法包括:确定加速踏板(APS)的踩踏程度是否等于或大于参考值,该参考值被设定为发动机进入全负载驱动模式的条件;在加速踏板的踩踏程度等于或大于参考值时,确定与发动机的部分负载驱动模式下的最大扭矩相对应的部分负载扭矩和与马达的最大扭矩相对应的马达扭矩;将部分负载扭矩和马达扭矩的总和与驾驶员所需扭矩进行比较;并且根据比较的结果控制发动机处于全负载驱动模式或部分负载驱动模式。
