A method for changing from electric operation to hybrid operation of a hybrid drive of a vehicle is achieved by the following steps: (a) detecting an increase in a target traction power; (b) starting the internal combustion engine; (c) outputting a positive torque when the internal combustion engine is started: generating a rising generator power (GL) by means of the generator device, the generator power (GL) being used together with the electric power (BL) of the vehicle-side electric power store to generate the electric traction power, the generator power (GL) being generated when the internal combustion engine has not yet been coupled or not completely coupled to the driven device; (d) completely coupling the internal combustion engine to the driven after starting to generate the rising generator power; and (e) after the internal combustion engine is fully coupled to the driven device: reducing the electric power of the accumulator for the electric traction to a non-positive value and adjusting the generator power (GL) according to a predetermined energy distribution. The invention further relates to a vehicle hybrid drive having a control device which is designed to carry out the method.
用于从车辆混合动力驱动装置的电力运行改变为混合动力运行的方法利用下列步骤实现:(a)检测目标牵引功率的提高;(b)启动内燃机;(c)当内燃机启动时输出正扭矩:借助于发电机装置产生上升的发电机功率(GL),发电机功率与车辆侧电力存储器的电功率(BL)一起用于产生电力牵引功率,发电机功率(GL)是在内燃机尚未耦合或尚未完全耦合到从动装置时产生的;(d)在开始产生上升的发电机功率之后,将内燃机完全耦合到从动装置;且(e)在内燃机完全耦合到从动装置之后:将用于电力牵引的存储器的电功率减小到非正值,并根据预定的能量分配来调整发电机功率(GL)。此外描述了车辆混合动力驱动装置,具有控制装置,其设置用于实施该方法。
