| 摘要 |
The invention relates to a drive system for an electrically driven vehicle, comprising an electric drive unit (4), a first power source circuit (1) comprising a control unit (14), which outputs controllable power, a second power source circuit (2), which can be charged and discharged and which is connected in parallel to the drive unit (4) and an intermediate electric circuit (5), which is connected to the first and second power source circuit (1, 2) and to the drive unit (4). A first detection device (11) detects an intermediate voltage (UZK) and a second detection device (12) detects a characteristic value of the vehicle speed (v). The control unit (14) is configured in such a way that it sets a modifiable target value (UZKsoll) fo r the intermediate voltage circuit in accordance with the characteristic value of the vehicle speed (v) and sets the power output of the first power source circuit (1) in accordance with the target value (UZKsoll) and the voltage (UZK) of the intermediate circuit. This permits the energy management in the drive system to be improved for several drive modes of the vehicle. |
