<p>PURPOSE:To improve the performance of an electric motor vehicle without the power driving and braking switching time by converting a brake converter to a suitable position in response to the running state of the vehicle. CONSTITUTION:A solenoid valve 2 is driven through the contact 5b of a speed relay in the state that a main circuit is not closed in a notch-off state in stopped state, and a brake converter is converted to a power driving state. When the main circuit is notched off in the running state, a solenoid valve 3 is driven through the contact 5c of the speed relay to convert it to the brake side. When the vehicle is redriven in power driving state, the solenoid valve 2 is driven through the contact 5a of the relay to convert it to the power driving state. Thus, it can eliminate the power driving and braking switching time by the power drive or brake command, thereby improving the performance of the vehicle.</p> |
