The invention relates to a method for operating a hybrid vehicle having an electric machine (3) as a first drive unit, a combustion engine (2) as a second drive unit, a disconnect clutch (4) connected between the combustion engine (2) and the electric machine (3), and a transmission (5) connected between the electric machine (3) and an output (6). When there is a request to close the disconnect clutch (4) on the control side and when there is a request to carry out an upshift on the control side, it is checked whether an upshift is required to prevent the vehicle-side rotational speed from reaching or exceeding a rotational speed limit value. When an upshift is required to prevent the vehicle-side rotational speed from reaching or exceeding a rotational speed limit value, the upshift is carried out in the transmission preferentially relative to the implementation of a closing process of the disconnect clutch. The invention also relates to a control device for operating a hybrid vehicle.
本发明涉及一种用于运行混合动力车辆的方法,混合动力车辆具有作为第一驱动机组的电动机器(3)、作为第二驱动机组的燃烧发动机(2)、连接在燃烧发动机(2)与电动机器(3)之间的分离离合器(4)以及连接在电动机器(3)与从动装置(6)之间的变速器(5)。当存在在控制侧使分离离合器(4)闭合的请求时并且当存在在控制侧实施升挡的请求时,检查是否需要升挡来避免车辆侧的转速达到或超过转速极限值。当需要升挡来避免车辆侧的转速达到或超过转速极限值时,相对于实施分离离合器的闭合过程而优先在变速器中实施升挡。本发明还涉及一种用于运行混合动力车辆的控制装置。
