<p><P>PROBLEM TO BE SOLVED: To provide a drive controller for electric vehicles, which can perform stable run according to a road condition such as wetting due to rainfall without performing operation by the judgement of a driver. <P>SOLUTION: The drive controller for electric vehicles includes torque command means 23 which outputs motor command torque Tr corresponding to accelerator opening, and an inverter device 22. The drive controller is provided with a road condition sensor which detects the condition of a road on which a vehicle runs, or a rain sensor 32 which detects rainfall. The torque command means 23 is provided with an accelerator property curve setter 28 in which a plurality of accelerator property curves a-d which show the relation between the accelerator opening and motor command torque Tr are set. Moreover, it is provided with an accelerator property switch 29 which switches the accelerator property curves a-d according to the detection signal of the road condition sensor, etc. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
