Electric road motor vehicle with switchable winding electric motor propulsion system

An electric road motor vehicle comprising:

• a chassis;
• a plurality of wheels being rotationally mounted on said chassis;
• a plurality of road vehicle tires being disposed on corresponding ones of said plurality of wheels;
• an electric motor assembly for driving said wheels to propel said electric road motor vehicle;
• said electric motor assembly comprising:
• an electric motor for driving at least one of said wheels of said electric road motor vehicle, said electric motor comprising a plurality of phase windings;
• a plurality of switches for selectively switching said electric motor, during operation of said electric motor, between a first operating state, wherein said electric motor assumes a first set of at least one operating parameter, and a second operating state, wherein said electric motor assumes a second set of at least one operating parameter;
• said plurality of switches each having:
• a first contact portion;
• a second contact portion;
• and
• switch portion means, said switch portion means being movable between said first and second contact portions to selectively contact either of said first and second contact portions;
• converter means for providing electrical power to said plurality of switches, said converter means having means for receiving direct-current electrical power and converting said received direct-current electrical power to alternating-current electrical power to be supplied to said electric motor;
• said electrical power to be supplied to said plurality of switches comprising electric currents having amplitudes;
• means for controlling said switches between said first and second operating states;
• said controlling means comprising means for controlling said converter means and for selectively reducing said amplitudes of at least said electric currents provided to said plurality of switches;
• and
• wherein said means for controlling said converter means comprises means for reducing, during switching of said electric motor between said first and second operating states, said amplitudes of said electric currents provided to said plurality of switches.
