Claims5
In combination in a motor vehicle having a first pair of wheels and a second pair of wheels:
- an electric motor for powering said first set of wheels;
- a combustion engine for powering said second set of wheels:
- an electrical energy storage device for transferring electrical energy to said electric motor:
- said electrical energy storage device comprising a fast charge-discharge battery:
- a cruise mode control circuit having preprogrammed cruise mode operating conditions which includes a vehicle operating speed exceeding a predetermined level and for a predetermined time interval, said control circuit automatically coupling said electric motor to said first set of wheels when said cruise mode operating conditions have not been satisfied and coupling said combustion engine to said second pair of wheels when said cruise mode operating conditions have been satisfied;
- said cruise mode control control circuit controlling said combustion engine to drive an electric power generator for charging said fast charge-discharge battery when said cruise mode conditions have not been satisfied;
- and
- user controlled means bypassing said control circuit for coupling said electric motor to said first set of wheels when said cruise mode conditions have been satisfied.

In combination in a motor vehicle having a first pair of wheels and a second pair of wheels:
- an electric motor for powering said first set of wheels;
- a quasi constant torque combustion engine for powering said second set of wheels:
- an electrical energy storage device for transferring electrical energy to said electric motor;
- said electrical energy storage device comprising a fast charge-discharge battery:
