This paper proposes a new active steering system for motorcycles, which may be thought of as a steer-by-wire system, together with controller design methods. One of the features of the system is to use only one motor taking system failure into account, while two motors are used in most steer-by-wire systems to provide the driver (rider) with shaped reaction torque. The proposed system can also provide reaction torque which cannot be shaped arbitrarily unlike the existing systems. In this way, the reduction of control freedom makes it more difficult to improve the maneuverability and safety simultaneously. With this mechanism, therefore, two operation modes; 1) normal driving, 2) emergency assist are considered, and sliding mode control and LQR theories are applied.
