気自動車の電気制動制御回路。 An accelerator signal circuit that detects whether or not the accelerator is activated and outputs it; a vehicle speed calculation circuit that calculates and outputs the vehicle speed based on the vehicle speed signal; a downhill slope sensor that detects and outputs the slope angle when going downhill; Electric braking vehicle speed setting that sets and outputs a safe speed that requires electric braking for safety reasons and a feeling speed that is lower than the safe speed and requires electric braking for feeling based on the slope angle signal detected by the slope sensor. The circuit is connected to each output of the accelerator signal circuit, the vehicle speed calculation circuit, and the electric braking operation vehicle speed setting circuit, and when the vehicle speed is equal to or higher than the stable speed by comparing whether or not the accelerator is activated and the vehicle speed with each of the set speeds, And when the vehicle speed is between the set feeling speed and the safe speed and the accelerator is not activated, electric braking is activated, and when the vehicle speed is between the set feeling speed and the safe speed and the accelerator is activated. Do not activate electric braking in
Electric braking for an electric vehicle, characterized in that it is equipped with an electric braking operation determination circuit that controls the electric braking so that the electric braking is not activated when the vehicle speed is less than or equal to the above-mentioned feeling speed without passing a running current. control circuit.
