置。 Turns on the drive transistor depending on the driving conditions
It is configured to control the traveling speed by changing the duty ratio, which is the ratio between the accelerator signal that operates to drive the motor and the brake signal that turns on the braking transistor and performs dynamic braking, and also detects the temperature of the control device. An overload control device for an electric vehicle, characterized in that when a signal value of a temperature sensor exceeds a reference value, the duty ratio is lowered to limit the current, and the brake signal is further switched to a neutral signal.
