1. A vehicle anti-runaway system, comprising:
a load calculation module, comprising:
a first storage unit configured to store a relationship between an engine performance and a load, a sprung mass, a centroid distance between a sprung centroid and a rotation center;
an inertial sensing unit configured to detect a tilt angle, a tilt angular velocity, a tilt angular acceleration and a lateral acceleration; and
a calculation unit configured to:
obtain the load corresponding to the engine performance according to the relationship between the engine performance and the load; and
obtain a load position according to a moment of inertia, the tilt angle, the tilt angular velocity, the tilt angular acceleration, the lateral acceleration, the load and the centroid distance; and
a runaway prevention module, comprising:
a second storage unit configured to store the centroid distance, the sprung mass, a rotation center distance and a wheelbase;
a maximum anti-overturn lateral acceleration calculation unit configured to obtain a maximum anti-overturning lateral acceleration according to the load position, the load, the centroid distance, the sprung mass, the rotation center distance and the wheelbase; and
a steering wheel control unit;
a brake control unit;
a throttle control unit; and
a control unit electrically connected to the steering wheel control unit, the brake control unit and the throttle control unit;
wherein the first storage unit, the inertial sensing unit and the calculation unit are physical circuits, the inertial sensing unit is a gyroscope, an acceleration sensor or a combination thereof, and the load and the load position is configured to obtain a maximum anti-overturning velocity;
wherein after obtaining the maximum anti-overturning velocity, the control unit controls the steering wheel of a vehicle through the steering wheel control unit, a brake of the vehicle through the brake control unit and/or a throttle of the vehicle through the throttle control unit so that the vehicle velocity of the vehicle does not exceed the maximum anti-overturning velocity.
