Examples of vehicles in scope and out of scope of ISO 26262:2018
Introduction.
Previously we discussed the scope of ISO 26262:2018. Here we will give examples of what vehicles are clearly in scope, vehicles that are clearly out of scope, and finally vehicles where it is not so clear.
For examples we assume that there is a safety related e/e system in the vehicle. We will use the UNECE categories where appropriate. This list is not exhaustive.
Examples of vehicles in Scope.
Road legal Motorcycle with either 2 or 3 wheels.
Series production cars. i.e. Category M1
Any size of Bus i.e. Categories M2, M3
Pick-Up Truck, Van i.e. Category N1
Any size of Commercial Truck i.e. Categories N2, N3
Trailers or Semi-Trailers i.e. Categories O1, O2, O3, O4
Examples of vehicles out of scope
In this section we will detail what vehicles are out of scope and give at least one reason why they are out of scope.
Trains - Not used on a road
Aeroplanes - Not used on a road
Ships/Boats or any type of watercraft - Not used on a road.
Armoured vehicles - Fits the definition of a Special Purpose Vehicle, which is out of scope in ISO 26262:2011. Special vehicles are out of scope in ISO 26262:2018. There is a difference in the term from the 1st to 2nd edition, of Special purpose vehicle and special vehicle. But it is believed to mean the same.
Fire Engines - Classified as a special purpose vehicle
Ambulances - Classified as a special purpose vehicle
Motor Homes - Classified as a special purpose vehicle
Hearse - The bodywork has had to be changed to make it into a hearse.
Prototypes - Is not a series production vehicle.
Mopeds - Specifically excluded in the scope definition.
Vehicles that are unclear
In this section we shall detail examples of vehicles where it can be argued either way whether they are in scope of ISO 26262:2018
Snowmobiles - It is unclear whether they fall into scope. Because they are clearly not designed for driving on anything other than snow. They can drive across roads, and they follow along the side of roads. In some countries they are required to be fitted with license plates, are taxed and have to be insured. But they are hard to call a road vehicle. But one of the uses they do have is on road. They have to use roads to get to petrol stations, and they have to cross roads. But is this minor use of roads enough to classify them as a road vehicle? Unclear.
ATV's. and SSV's Are used on roads, but their main use is away from roads. Is the time they spend on roads enough to put it in scope?
Agricultural and Forestry tractors. Again agricultural tractors are used on roads, they are fitted with indicators, license plates etc. But does their main use is on the farm or on the land. The road use is necessary to get around from the farm to the land.
