Method And Control Apparatus For Recuperating Energy In A Hybrid Vehicle |
摘要 |
A method and apparatus for recuperating energy in a hybrid vehicle, having an internal combustion engine an electrical machine, and on-board electrical system with an energy store that can be charged with electrical energy during a recuperation operation. A recuperation power for a recuperation operation of the electrical machine is set to a first value that allows a recuperation operation with a maximum generator capacity of the electrical machine if an actual energy level of the energy store is lower than or equal to a threshold value. However, the recuperation power for a recuperation operation is set to a second value lower than the first value and allows a recuperation operation with a reduced generator capacity of the electrical machine if the actual energy level of the energy store is greater than the threshold value. |

1. A method for recuperating energy in a hybrid vehicle having an internal combustion engine, an electrical machine, an automatic stop/start apparatus configured to automatically turned off and start the internal combustion engine under predetermined conditions, and an on-board electrical system with an energy store configured to be charged with electrical energy by the electrical machine during a recuperation operation, comprising
(a) setting a recuperation power (P_act) for the recuperation operation of the electrical machine to a first value (P_max) which allows the recuperation operation with a maximum generator capacity of the electrical machine if an actual energy level (E_act) of the energy store is lower than or equal to a threshold value (E_3); and (b) setting the recuperation power (P_act) for the recuperation operation of the electrical machine to a second value (P_lim) which is lower than the first value (P_max) and allows the recuperation operation with a reduced generator capacity of the electrical machine if the actual energy level (E_act) of the energy store is greater than the threshold value (E_3). |
