What is ISO 21202— Partially automated lane change systems about?
ISO 21202 contains the basic control strategy, minimum functionality requirements, basic driver interface elements, minimum requirements for reaction to failure, and performance test procedures for PALS. PALS performs part or all of lane change tasks under the driver’s initiation and supervision.
ISO 21202 specifies PALS which is intended to function on roads with visible lane markings, where non-motorized vehicles and pedestrians are prohibited, and to perform a lane change into a lane with traffic moving in the same direction.
Note 1: The use of PALS is intended for light-duty and heavy-duty vehicles (heavy trucks and buses).
Note 2: Support on sections of roadway with temporary or irregular lane markings (such as roadwork zones) is not within the scope of ISO 21202.
Who is ISO 21202— Partially automated lane change systems for?
ISO 21202 on Partially automated lane change systems (PALS) is useful for:
- Light-duty and Heavy-duty vehicle manufacturing companies
- Emergency vehicle notification systems
- Vehicle manufacturing companies
- Traffic signal control systems
- Traffic navigation systems
- ITS station units
Why should you use ISO 21202— Partially automated lane change systems?
In general, driving assistance systems and automated driving systems equipped in a vehicle reduce the burden of the drivers and contribute to safe driving. For a lane change operation, there are many drivers who are not good at performing a lane change. To support such drivers, Partially Automated Lane Change Systems (PALS) execute an automatic lane change manoeuvre following the request of the driver and under the supervision of the driver, on a road with visible lane markings, where non-motorized vehicles and pedestrians are prohibited.
ISO 21202 specifies how PALS supports drivers for a lane change and describes PALS' operations. It presents you PALS, that acquire information not only on the position of the vehicle within the lane but also on adjacent lanes and obstacles in the vicinity of the subject vehicle (SV).
It helps you evaluate whether or not a lane change to an adjacent lane is possible and sends commands to the actuators which control the lateral movement of the vehicle to perform a lane change.
