New Chinese Standards on Advanced Driver Assistance Systems Published
Reflecting the increasing availability of advanced driver assistance systems (ADAS) on modern vehicles, the Chinese Government have recently published three new standards which specifically cover advanced driver assistance systems.
The first of these new standards is GB/T 39263-2020 on terms and definitions for advanced driver assistance systems (ADAS). The standard specifies definitions for a wide variety of different systems, which are split into two categories; information assistance systems and control assistance systems. The information assistance systems category includes definitions for systems such as driver attention monitoring systems, traffic sign recognition systems, forward collision monitoring systems, lane departure warning systems and blind spot detection systems. The control assistance category includes definitions for systems such as advanced emergency braking systems, automatic emergency steering systems, lane keep assist systems and adaptive cruise control.
The other two new Chinese standards cover two of the systems which are defined within GB/T 39263-2020; blind spot detection systems and lane keep assist systems.
The new Chinese standard on blind spot detection systems, GB/T 39265-2020, specifies requirements for all M and N category vehicles, i.e. passenger vehicles and goods vehicles. For M1 and N1 category vehicles, i.e. passenger cars, multipurpose passenger vehicles, pick-up trucks and vans, the standard specifies technical requirements and test procedures for blind spot detection systems which can detect the presence of vehicles, including motorcycles, in specified areas on both the right and left hand side of the vehicle and alert the driver when a vehicle is present in these areas. The test procedures specified to determine the performance of the blind spot detection system cover a variety of scenarios, e.g. the subject vehicle being overtaken by another vehicle on a single carriageway road, the subject vehicle being passed by vehicle in another lane on a carriageway with multiple lanes, etc., at various test speeds.
For M2, M3, N2 and N3 category vehicles, i.e. buses, coaches and heavy trucks, the standard specifies similar requirements to those specified for M1 and N1 category vehicles for blind spot detection systems, but also specifies technical requirements and test procedures for right turn blind spot detection systems which can detect the presence of cyclists in a specified area on the right hand side of the vehicle, when the vehicle is turning right, and alert the driver when a cyclist is present in this area.
The new Chinese standard on lane keep assist systems, GB/T 39323-2020, covers requirements for M1 category vehicles, i.e. passenger cars and multipurpose passenger vehicles, fitted with lane keep assist systems which operate within a speed range from 70 km/h to 120 km/h. The standard specifies technical requirements and test procedures for two variations of lane keep assist systems; lane departure prevention systems and lane centring systems. Lane departure prevention systems only intervene when an impending departure from the current lane is detected, whereas lane centring systems operate continuously to ensure that the vehicle remains within its current lane. For both variations of lane keep assist systems, test procedures are specified to determine the performance of the system on both straight and curved roads.
All three of these new Chinese standards become effective from June 1, 2021.
