Electric wheeled device

An electric wheeled device, comprising:

• a vehicle frame;
• a power supply device supplying power to the electric wheeled device;
• a traveling assembly mounted to the vehicle frame, coupled to the power supply device, and comprising traveling wheels and traveling motors, the traveling wheels comprising a first traveling wheel and a second traveling wheel, and the traveling motors comprising a first traveling motor for driving the first traveling wheel and a second traveling motor for driving the second traveling wheel;
• an operating assembly operable by a user to indicate a first operation amount that is used for controlling the first traveling wheel and a second operation amount that is used for controlling the second traveling wheel, wherein the first operation amount comprises a corresponding first preset rotational speed, and the second operation amount comprises a corresponding second preset rotational speed;
• and
• a traveling control device coupled to the traveling assembly and the operating assembly, the traveling control device driving the first traveling motor at a first target rotational speed and driving the second traveling motor at a second target rotational speed when the first operation amount is different from the second operation amount;
• wherein the first target rotational speed is a smaller one between the first preset rotational speed and a first limit rotational speed, the second target rotational speed is a larger one between the second preset rotational speed and a second limit rotational speed, and the second limit rotational speed corresponds to the first target rotational speed.

• and
• a traveling control device coupled to the traveling assembly and the operating assembly, the traveling control device converting the first operation amount into a first preset rotational speed and converting the second operation amount into a second preset rotational speed;
• wherein, when the first operation amount is different from the second operation amount, the traveling control device reduces the first preset rotational speed to obtain a first target rotational speed, obtains a second target rotational speed based on the first target rotational speed, drives the first traveling motor based on the first target rotational speed, and drives the second traveling motor based on the second target rotational speed, and the second target rotational speed is greater than or equal to the second preset rotational speed.
