intelligent balancing two wheeled vehicle acceleration or deceleration operation is also very simple, to drivers and balance of the car itself the centre of gravity of the whole vertical axis as a benchmark, when the driver body tilted forward, gyroscope Senses Center of gravity forward force, allow the motor to generate to allow vehicles along the acceleration; on the contrary, when the driver leaned back, gyroscope will be perceived center of gravity vertical axis tilted backwards, the motor produces backward force to achieve balance result.
