  "textContent": "Provided is a vehicle-type driving device. The vehicle-type driving device provided in the present application includes a traveling assembly including multiple traveling wheels; a steering wheel configured to control the vehicle-type driving device to steer; a traveling motor for driving the vehicle-type driving device to steer at a target angular velocity, where the ratio of the target angular velocity to the change in the steering angle of the steering wheel is defined as a steering ratio; and a control device configured to, when the traveling speed of the vehicle-type driving device is within a preset range, set the steering ratio according to a steering ratio curve function, where variables of the steering ratio curve function include the steering angle of the steering wheel and the traveling speed of the vehicle-type driving device. In this manner, the steering feel of the vehicle-type driving device at different speeds can be improved, the problem of poor operating feel for a driver driving and turning can be solved, and the operating experience of the user can be improved.",
