According to one embodiment, acceleration and deceleration profiles can be generated and applied dynamically when a condition exist necessitating a change in the velocity of an autonomously controlled vehicle. An acceleration or deceleration profile can be generated when conditions exist necessitating a change in velocity and according to a smoothing function and based on a set of control parameters such as a target velocity, a determined time to reach the target velocity, and a maximum rate of change for the velocity of the vehicle. The smoothing function can be non-linear and can produce a profile representing a curve having a lower rate of change in the velocity of the vehicle at a beginning and an end of the curve than in a middle of the curve. In this way, changes in velocity can be more gradual at a beginning and end of the change and more aggressive in the middle.
