Abstract
Methods and systems are provided for a hybrid transmission. In one example, a method for a hybrid transmission, comprising, adjusting voltage on an inverter of an electric motor prior to disconnecting or connecting a battery contact in response to a transition between a first mode and a second mode. In the first mode, a battery and at least the electric motor are used to power rotation of a transmission output shaft. In the second mode, an engine and at least the electric motor are used to power rotation of the transmission output shaft. In one example, the adjusting is initiated in response to a request to transition between the first mode and the second mode. In one example, the method includes controlling current to the battery to within a non-zero threshold of zero in response to the request to transition the first mode to the second mode.
