<p>The method involves determining the control of power flow from the batteries of the electrically powered vehicle to the drive motor by a computer. The controls are applied to the wave form, phase shift and frequency of current in the motor. During manufacture a number of motors are tested and the relation between controls and motor variables giving optimal performance are determined, and stored in memory. Different sets of data are stored (3,4) for different driving modes, for example moderate or sporting. The driver can select (2) between these modes. The computer (5) monitors the motor (10) variables and delivers these to the control computer (6), which also receives input from driver controls (1,2,3) and from the stored tables (3,4) of motor data. The computer uses these inputs to determine drive to the motor.</p> |
