A hybrid vehicle has an internal combustion engine, electrical machine, electrical starter, high and low voltage batteries and DC/DC convertor. On starting (40) the engine water temperature is measured (41) and the electrical machine (43,50) or the starter (44,46,49) are used depending on availability (42,45,48) and on temperature. For temperatures between -24 and -8 degrees Centigrade the batteries are interconnected An Independent claim is also included for : A hybrid vehicle with internal combustion engine, electrical machine, electrical starter and high and low voltage batteries which uses engine cooling water temperature and machine availability to determine whether the starter or the electrical machine should be used to start the power unit and whether the batteries should be interconnected by convertor |
