THEMATIC CERTIFICATION SCHEME FOR BLIND SPOT MONITORING SYSTEM
ATIC has sorted out the blind spot monitoring system thematic matrix from the legal requirements, applicable models, monitoring scope, test items, etc. as follows:

THE SYSTEM IS BRIEFLY ANALYZED AS FOLLOWS
UN R151 Blind Spot Information System （BSIS）：On November 15, 2019, the Blind Spot Information System BSIS regulation UN R151 officially came into force, and its addendum Amendment 1 officially came into force on September 25, 2020, and recently on July 6, 2021 the United Nations has issued a new addendum Amendment 2, Amendment 2 has officially come into force on June 9, 2021, the document officially revised the scope of application of the blind spot information system, expanding the scope of application from vehicles of categories N2 (> 8 t of technically permissible maximum mass) and N3 to M2, M3, N2, and N3. The regulation will be mandatory for M2, M3, N2, N3 new models on July 6, 2022.
Field of detection：The monitoring range of R151 is the right side blind zone of the left-hand drive vehicle, mainly to remind the driver that there are pedestrians or bicycle riders within the blind zone when the vehicle is about to turn right, so as to avoid accidents.

 
UN R158 Devices for Reversing Motion：The purpose of this Regulation is to provide the provisions for reversing motion concerning on awareness of vulnerable road users proximity. UN Regulation No. 46. provides the provisions for indirect vision of motor vehicles. This Regulation expands driver’s vision or awareness for vehicle rear direction when in reversing motion. Therefore, some requirements of this Regulation may be satisfied by devices complying with UN Regulation No.46. The regulation has entered into force on June 10, 2021 and will be enforced on July 6, 2022.
Field of detection：R158 monitoring range is mainly for the rear side of the vehicle's blind spot, when backing up, if the traditional rearview mirror drivers are unable to observe the situation on the rear side of the vehicle, will cause the corresponding accident risk. Common model configurations are rear parking radar + rear reverse image or rear parking radar + 360 ° panoramic visual parking assistance system.

UN R159 Moving-Off Information Systems (MOIS)："Moving Off Information System (MOIS)" means a system to detect and inform the driver of the presence of pedestrians and cyclists in the close-proximity forward blind-spot of the vehicle and, if deemed necessary based on manufacturer strategy, warn the driver of a potential collision. The regulation has entered into force on June 10th, 2021 and is applicable to M2,M3,N2,N3. The regulation will be mandatory for M2, M3, N2, N3 new models on July 6, 2022.
Field of detection：The monitoring range of R159 is the blind zone in front of the vehicle, this is usually when the vehicle starts from a standstill or at a speed of no more than 10km/h at low speed in a straight line, the MOIS system will detect and inform the driver of the presence of pedestrians and bicyclists in the front of the vehicle in the close blind zone.

The monitoring scopes of these three systems are simplified as follows:
