Narrow vehicles have multiple advantages but tend to have a limited application because they are roll unstable. The use of flywheels to increase their stability is a known method but the operation range, complexity, performance and cost usually limit the application of these vehicles. Stability and agility enhancement system and method enabling the application of stabilizing forces from flywheels and the steering of the trajectory concurrently and cooperatively with the driver's steering and assistance enable the benefit of reduced cost and complexity while providing enhanced performances, intuitive control, safety and operation range.

When an external detection device detects an obstacle (another vehicle (T)) on either a left or right side of the own vehicle (M), a control device of a steering assistance device for a saddle type vehicle controls an assist torque so that a handle operation to the side opposite to the side on which the obstacle is detected becomes heavier (more difficult to turn) than a case in which the obstacle is not detected. The handle operation to the side on which the obstacle is detected makes a handle relatively light (makes it easier to turn) while steering assist is maintained.
