The invention discloses a rapid control prototyping of active front wheel steering, and belongs to the field of steering control systems. The rapid control prototyping is characterized by comprising an active front wheel steering system, a motor controller and a host machine, wherein the active front wheel steering system comprises a steering wheel, a bearing, a steering wheel corner sensor, a steering wheel torque sensor, a steering shaft, a steering shaft corner sensor, a steering device and a motor; the steering wheel is connected with a bearing outer ring; the top end of the steering shaft is connected with a bearing inner ring; the bottom of the steering shaft is mechanically connected with the steering device; a data acquisition board card and an AFS controller are arranged in the host machine; the sensors are connected with the data acquisition board card through signal lines. According to the rapid control prototyping disclosed by the invention, a conventional motor and a conventional steering device of an electric power steering system are reserved, and the structure of the system of the rapid control prototyping is simplified, so that the cost is reduced. The steering wheel and the steering shaft are connected through the bearing, so that good road feel can be kept, and the function of a line control system can be realized. Through the adoption of the rapid control prototyping disclosed by the invention, the correctness and the feasibility of an AFS control algorithm and strategy can be quickly validated, so that the developing efficiency is improved.
