Abstract
An electric motor vehicle comprises as a drive system a battery, a motor, and a controller for controlling the rotation of the motor. The electric motor vehicle disposes an accelerator for controlling speed of the motor, a key switch for turning on or off the motor and the controller, a circuit for judging an opening/closing state of the accelerator when the key switch is turned on, and a circuit for preventing the rotation of the motor when the key switch is turned on with the accelerator open.
Claims3
An electric motor vehicle having as a drive system a battery, a motor, and a controller for controlling rotation of the motor, comprising an accelerator for controlling speed of the motor, a key switch for turning on or off the motor and the controller, a circuit for judging an opening/closing state of the accelerator when said key switch is turned on, and a circuit for preventing the rotation of the motor when the key switch is turned on with the accelerator open.
An electric motor vehicle having as a drive system a battery, a motor, and a controller for controlling rotation of the motor, comprising:
- an accelerator for controlling speed of the motor,
- a switch for prohibiting running, and
- a travel prohibiting circuit which judges opening/closing of the accelerator and maintains a travel prohibiting state even when the switch is released with the accelerator being open, wherein the travel prohibiting state, which is continuously maintained by the travel prohibiting circuit even when the switch is released with the accelerator open, is shifted to a travel allowing state by closing the accelerator.
