A method for controlling an autonomous or semi-autonomous vehicle comprises: obtaining, information describing a roadway from a starting position to make progress along the roadway between a left edge and a right edge; transforming the information describing the roadway in a Frenet-Serret frame; defining a plurality of grid lines along the roadway at spaced locations; determining corridors in space and time coordinates; determining a trajectory within the suitable corridor through mathematical optimization for each grid line in time generating a convex (or quasi-convex) and continuous time function in the drivable space; and transforming the convex (or quasi-convex) and continuous time function into a motion planning trajectory in Euclidian coordinates. Furthermore, this method applies different methods in determining the development of the vehicle states over time for high and low velocities of the vehicle.
