Blind Spot Information System European Type Approval
Turning manoeuvres involving collisions between trucks turning right and cyclists, typically occurring at lower driving speeds or standstill, usually have serious consequences for vulnerable road users (VRU). In the past, the safety of VRU was raised by an improvement of the truck driver's vision by increasing the number of mirrors and by equipping trucks with side underrun protection. Since turning accidents still happen and Blind Spot Information System (BSIS) have been introduced in a lot of vehicle segments, BSIS means a system installed on a truck to inform the driver of a possible collision with a bicycle near side, it is obvious to use such assistance systems for avoiding accidents between turning trucks and cyclists.
The United Nations Economic Commission for Europe (UNECE) officially announced the technical regulations UN R151 related to the blind spot monitoring system. The UN R151 regulation has come into effect on November 15, 2019. Considering the international influence of the UNECE regulation, it can be foreseen to increase More countries will adopt UN R151 as the technical standard of their blind spot monitoring system.

UN R151 Certification, BLIND SPOT INFORMATION SYSTEM FOR HEAVY VEHICLES
When a truck is turning, it is easy to collide with a bicycle due to its limited visibility. This situation generally ...
The first application for a manufacture to an authority generally requires initial assessment. In most of the cases ATIC experts will conduct the onsite initial assessment. Some authority can exempt onsite initial assessment by accepting ISO/IATF certificates.
According to EU/UN Regulations information document including sufficient drawings of the vehicle/component shall be prepared and submitted to technical service by the manufacture/applicant. ATIC experts also can support manufacture/applicant to prepare information document based on CAD drawings and vehicle/component specifications.
In most of the cases ATIC experts will witness testing in 3rd party testing lab and draft technical reports. If the manufacture is equipped with competent facilities it's also possible to make witness testing using manufacture's facility
ATIC experts will conduct lab assessment before witness testing and draft lab assessment report.
Information Documents, Technical Reports as well as other technical documents if needed will be submitted to relevant authority. Authority will review and issue type approval certificate if all the documents, tests, drawings fulfill the regulations and requirements.A typical lead-time for this review process is 4 to 6 weeks.
After the approval the CoP audit/test maybe conducted based on regulations and authorities' requirements
Other Key Points
- This Regulation applies to the blind spot information system of vehicles of categories N2 (> 8 t of technically permissible maximum mass) and N3. Vehicles of categories N2 (≤ 8 t of technically permissible maximum mass), M2 and M3 may be approved at the request of the manufacturer.
- The requirements of this Regulation are so worded as to apply to vehicles which are developed for right-hand traffic. In vehicles that are developed for left-hand traffic, these requirements shall be applied by inverting the criteria, when appropriate.
- Generally, initial assessment is required, and the CoP audit is required from time to time after the type approval certificate is issued. The CoP policies of different Ministry of Transportation departments are slightly different.
EU/UNECE type approvals are granted to the Manufacturer
- No matter where the products to be approved are manufactured - If the manufacturer is located outside the European Economic Area and applies for a WVTA the manufacture shall appoint a representative located in EEA - For other type approvals the manufacture can appoint a representative located in EEA - Actions/declarations of the representative have the same effect as of those made by the (future) approval holder
- Type Approval (Mandatory)
- Ministry of Transportation
Blind Spot Information System
Blind Spot Information System (BSIS) means a system to inform the driver of a possible collision with a bicycle near side.
Near side means the side of the vehicle near the bicycle. The near side of the vehicle is the right side for right-hand traffic.
Bicycle means a combination of a bicycle and cyclist, the test device according to ISO [CD] 19206-4 .
Collision point means the position where the trajectory of any vehicle point would intersect with any bicycle points if a turn by the vehicle is initiated.
Impact Position means the location of impact of the bicycle on the right side of the vehicle with respect to the vehicle front right corner, when both vehicles have reached the collision point.
Blind Spot Information System
BSIS is a system installed on a truck that informs the truck driver of a possible collision with a bicycle on the near side so that the driver can take timely action to avoid a traffic accident. The system involves two types of alert signals, information signals and warning signals.
▸ Information Signal
▸ Warning Signal
Fundamentals: BSIS uses an optical information signal to inform the truck driver that there is a bicycle nearby. If the bicycle has been driving in a critical area where a collision may occur, the information signal will always remain to remind the truck driver. The information signal shall only be deactivated automatically in case of system failure or contamination of the sensors; a manual deactivation shall not be possible. This information signal shall be visible by daylight and at night. The device emitting the information signal shall be located at the near side at a horizontal angle greater than 30° towards an axis parallel to the longitudinal median plane of the vehicle and going through the ocular reference point.
Features: Low intensity Low annoyance if issued too often Lesser effect in steering driver's attention > 30° to the right of the driver Only automatic deactivation (ice, snow on sensors, ...)
Dynamic Test: The truck and bicycle are both in motion and the bicycle enters a critical area of potential collision with the truck, but the truck driver does not yet have the intent to turn and an informational signal alert appears.
Static Test: The truck is stationary, the bicycle is moving, the bicycle enters horizontally or vertically into a critical area where it may collide with the truck, and an information signal appears.
The warning signal shall be activated at the earliest when the system detects a potential collision, e.g. by the intention of a turn towards the bicycle, e.g. by evaluating the distance between or trajectory intersection of vehicle and bicycle, direction indicator activation or similar. If it is the optical signal, this signal shall be visible by daylight and at night. The warning signal is different from the information signal in the mode or start strategy. It is easy for the driver to understand and associate it with the potential danger. This warning signal can be manually or automatically deactivated. In the event of malfunction or sensor contamination, it disabled with the information signal.
Features: If issued right, good effects in steering driver‘s attention High annoyance if issued too often Different to information signal in mode or activation strategy Activation strategy decided by Vehicle Manufacturer （ manually or automatically deactivated ） not before collision becomes imminent
Dynamic Test: Both trucks and bicycles are moving, the bicycle enters a key area that may collide with the truck, and the truck driver intends to turn. When BSIS evaluates the intersection of the trajectory or detects the operation of the turn indicator on the steering wheel, a warning signal appears to remind. The verification of the warning signal is achieved through technical document review.
Static Test: The truck is stationary, the bicycle is moving, and the bicycle enters the key area that may collide with the truck horizontally or vertically, and an information signal or warning signal appears. The verification of the warning signal is achieved through technical document review.
