CONTROL DEVICE FOR ELECTRIC VEHICLE
First Claim
Patent Images
1. An electric vehicle, comprising:
- an accelerator mechanism including an accelerator grip configured to enable operation of an accelerator for increasing a throttle opening in a first direction from a minimum opening in a normal moving region, and including a spring configured to restore the throttle opening on a side of the minimum opening when the accelerator grip is not operated;
a driving section configured to drive a motor according to the throttle opening by the accelerator mechanism;
a control device including a creep speed moving region set in a second direction reverse to the first direction from the minimum opening, and including position regulating unit provided between the normal moving region and the creep speed moving region;
wherein the accelerator mechanism is configured to operate the throttle opening from the minimum opening to the creep speed moving region further set in the second direction reverse to the first direction against the position regulating unit,wherein the spring is configured to push the accelerator grip up to a creep speed reference opening located in a middle of the creep speed moving region so as to reduce the throttle opening, andwherein the control device further includes a creep speed control section configured to supply a motor driving instruction to the driving section to make the electric vehicle advance at a predetermined minute vehicle speed in a region in which the throttle opening is larger with the creep speed reference opening as a criterion in the creep speed moving region, and to make the electric vehicle back at the predetermined minute vehicle speed in a region in which the throttle opening is smaller with the creep speed reference opening as the criterion, in the creep speed moving region.

Abstract
In an electric vehicle, a throttle spring restores a throttle opening on the side of a minimum opening when the accelerator is not operated. A driving section drives a motor according to the throttle opening. The throttle spring pushes an accelerator grip to a creep speed reference opening so as to reduce the throttle opening. A creep speed control section supplies a motor driving instruction to the driving section so that the electric vehicle is advanced at minute vehicle speed. The electric vehicle can also be backed at predetermined minute vehicle speed when the throttle opening is smaller than the creep speed reference opening.

14. An electric vehicle, comprising:
-
accelerator means for controlling operation of an accelerator for increasing a throttle opening in a first direction from a minimum opening in a normal moving region, said accelerator means including accelerator grip means and spring means, said accelerator grip means for actuation by a rider to increase the throttle opening, and spring means for restoring the throttle opening on a side of the minimum opening when the accelerator grip is not operated; driving means for driving a motor according to throttle opening by the accelerator means; control means for controlling the driving means, said control means including a creep speed moving region set in a second direction reverse to the first direction from the minimum opening, said control means also including a position regulating means provided between the normal moving region and the creep speed moving region, wherein the accelerator means is also for operating the throttle opening from the minimum opening to the creep speed moving region further set in the second direction reverse to the first direction against the position regulating means, wherein the spring means is for pushing the accelerator grip up to a creep speed reference opening located in a middle of the creep speed moving region so as to reduce the throttle opening, and wherein the control means further includes creep speed control means for supplying a motor driving instruction to the driving means to make the electric vehicle advance at a predetermined minute vehicle speed in a region in which the throttle opening is larger with the creep speed reference opening as a criterion in the creep speed moving region, and to make the electric vehicle back at the predetermined minute vehicle speed in a region in which the throttle opening is smaller with the creep speed reference opening as the criterion, in the creep speed moving region. - View Dependent Claims (15, 16, 17, 18, 19, 20)
