CONTROL DEVICE FOR ELECTRIC VEHICLE
First Claim
1. A control device for an electric vehicle provided with a motor that operates the vehicle according to a speed instruction according to a throttle opening by an accelerator operating means, comprising:
- a mode switch provided separately from the accelerator operating means for selecting either of a normal mode or a backing up mode of the vehicle;
mode discriminating means for discriminating that the backing up mode is selected by the mode switch on the premise that at least the throttle opening is zero and vehicle speed is zero; and
a driving section for supplying a creep speed backing up instruction determined in a creep speed range in which a vehicle speed lower than a maximum vehicle speed in the normal mode is a maximum speed for the motor when the backing up mode is selected by the mode discriminating means.

Abstract
A control device for a creep speed advance and creep speed backing up of an electric vehicle. A mode switch provided with an operating section can be operated in a longitudinal direction and can be operated leftward from an intermediate part. The operating section is automatically returned to a stop position in which a speed zero instruction is output to a motor when not being operated by return springs. When the operating section is pushed forward, a creep speed advance mode can be selected and when the operating section is pulled backward, a creep speed backing up mode can be selected. To clearly discriminate a position of the operating section among the creep speed advance mode, the creep speed backing up mode and a normal mode, a stopper is arranged between the stop position and the normal mode so that larger force is required to operate the operating section.
