UN Regulation No. 151 (R151), phased in since 2020, requires new goods vehicles over 8 tonnes to fit a Blind Spot Information System (BSIS) that detects vulnerable road users (VRUs) such as pedestrians and cyclists approaching the right side and front-side, issuing graded warnings when they fall within the driver's blind spot.
The regulation sets clear demands on detection range, response time and false-alarm rate. zerow 77Ghz mmWave radar provides high-resolution detection of fast-approaching vehicles and targets in adjacent lanes and the side-rear, with up to 50m range and <0.18m ranging accuracy, plus temperature compensation for a -40℃~85℃ operating range.
For the R151 use case, zerow's BSD solution links radar perception with audible/visual alerts and in-cabin prompts: a cabin indicator warns first, and if the target keeps approaching, external sound-light warning triggers—helping drivers avoid accidents during turning and pull-away. The solution supports both OEM and retrofit deployment with truck makers and modifiers.
