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:
- an accelerator grip mounted on a first side of the electric vehicle and operatively connected to the throttle opening for normally controlling the speed of the electric vehicle;
a mode switch mounted on a second side of the electric vehicle displaced relative to the accelerator grip, said mode switch being provided separately from the accelerator operating means for selecting either of a normal mode or a backing up mode of the vehicle, said mode switch being configured to be able to select a stop position corresponding to a position in which a single operating section is operated in addition to the normal mode and the backing up mode of the vehicle and said mode switch is provided with return springs configured to be able to be displaced among each switched position of the normal mode, the backing up mode and the stop position and which automatically returns the mode switch to the stop position set in an intermediate part of switched positions of the normal mode and the backing up mode in a free state in which no operating external force is applied;
mode discriminating means for detecting that the backing up mode is selected by the mode switch when 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 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.

14. A control device for an electric vehicle provided with a motor, comprising:
-
an accelerator grip mounted on a first side of the electric vehicle and operatively connected to the throttle opening for normally controlling the speed of the electric vehicle; a mode switch mounted on a second side of the electric vehicle displaced relative to the accelerator grip, said mode switch selecting either of a normal mode or a backing up mode of the vehicle; mode discriminating means for detecting that the backing up mode is selected by the mode switch when at least a 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 when the backing up mode is selected by the mode discriminating means; wherein the mode switch is composed of a first switch for switching validity and invalidity of the normal mode and a second switch which is turned valid when the first switch is turned invalid and in which either of the stop or the backing up mode can be selected. - View Dependent Claims (15, 16, 17)
