Optimal operating condition determining method for hybrid vehicle, involves detecting temperature of electric motor as parameter, and determining optimal operating condition by consideration of parameters and torque demand at drive chain

摘要

The method involves detecting a temperature (T) of an electric motor (EM) as a parameter, and considering a topographic parameter and/or environmental parameter and/or vehicle parameter such as loading condition (B) of the vehicle detected by manual entry and/or slope (N) of the vehicle in a longitudinal direction detected by a slope sensor and/or battery charging condition (BLZ), as another parameter. An optimal operating condition is determined by a control unit (SE) based on a torque demand at a drive chain of a vehicle and by consideration of the detected parameters.
