The invention discloses a dynamic gear switching control method for a hybrid electric vehicle, which comprises the following steps of: dividing vehicle speed judgment conditions into a first condition, a second condition and a third condition, after the vehicle is electrified at high voltage, enabling the vehicle to be at any one of a P gear, an R gear, an N gear and a D gear, and according to the vehicle speed and the state of a brake pedal, combining with the operation intention of a driver; whether the gear is allowed to be switched to the target gear of the driver or not is judged; the first condition is that the vehicle speed is larger than-3 kph and smaller than 3 kph, the first condition is that the vehicle speed is larger than-7 kph and smaller than-3 kph or larger than 3 kph and smaller than 7 kph, and the third condition is that the vehicle speed is larger than 7 kph or smaller than-7 kph. According to the dynamic gear switching control method for the hybrid electric vehicle, by formulating the reasonable dynamic gear shifting strategy, the situation that the vehicle may be dangerous due to misoperation of a driver or an unreasonable gear shifting request can be avoided, and the safety of the vehicle and the driver is guaranteed.

    本发明公开了一种混合动力汽车动态挡位切换控制方法,将车速判断条件分为第一条件、第二条件和第三条件,车辆高压上电后,车辆处于P挡、R挡、N挡和D挡中的任一档位,根据车速和刹车踏板状态,结合驾驶员操作意图,判断此时是否允许将档位切换至驾驶员目标档位;第一条件为‑3kph<车速<3kph,第一条件为‑7kph<车速<‑3kph或3kph<车速<7kph,第三条件为车速>7kph或车速<‑7kph。本发明的混合动力汽车动态挡位切换控制方法,通过制定合理的动态换挡策略,可以避免驾驶员的误操作或者不合理的换挡请求可能导致车辆发生危险,保证车辆及驾驶员的自身安全。
