Longitudinal controller

-


•The basic functions of automated longitudinal vehicle control are keeping the vehicle a safe distance behind another vehicle.
•maintaining a relatively constant speed with the least brake use and applying the brake as fast as possible in emergency situations.
•The control of the vehicle's speed and its adaptation to road features, using the throttle and the brake pedal as needed.
•Longitudinal controller has the main roll to avoid collision when vehicles which are following each other.

3.1.3. Proportional–integral–derivative controller

-

A  proportional–integral–derivative controller ( PID controller  or  three-term controller ) is a control loop feedback mechanism widely used in industrial control systems and a variety of other applications requiring continuously modulated control. A PID controller continuously calculates an  error value   {\displaystyle e(t)}  as the difference between a desired setpoint (SP) and a measured process variable (PV) and applies a correction based on proportional, integral, and derivative terms (denoted  P ,  I , and  D  respectively), hence the name. In practical terms it automatically applies accurate and responsive correction to a control function. An everyday example is the cruise control on a car, where external influences such as hills (gradients) would decrease speed. The PID algorithm restores from current speed to the desired speed, with small delay an...
