Question

To maintain a constant velocity profile in a trajectory generation algorithm, which derivative of the position function must be restricted to ensure passenger comfort?

Accepted Answer

To maintain passenger comfort while ensuring a constant velocity profile, the third derivative of the position function, known as jerk, must be restricted. In physics and motion control, position is the location of an object, velocity is the rate of change of position over time, and acceleration is the rate of change of velocity. Jerk is the rate of change of acceleration over time. When a vehicle or robotic system changes its velocity, it undergoes acceleration. If that acceleration changes abruptly, passengers experience a sudden, jarring physical sensation. By restricting jerk, you ensure that any change in acceleration occurs smoothly over time rather than instantaneously. This limitation prevents the physical discomfort caused by sudden forces acting on the human body, such as the feeling of being thrown forward or backward when a vehicle starts or stops too quickly.
