Bosch Group has developed a lane-changing assistant that helps in reducing the blind spot of a vehicle, which uses a new mid-range radar (MRR) sensor for rear-end applications. Blind spot is the area that is not covered by either the inside or outside rear view mirrors, which is especially dangerous while changing lanes.
This MRR technology is based on fourth-generation Bosch radars, and can be used in assisting drivers in more than just lane changes, the company said. A leading European carmaker is currently claimed to be using Bosch’s MRR rear sensor system for rear-end applications into series production. The MRR rear sensors monitor areas alongside and behind the car, with powerful control software analysing this information to create a complete picture of traffic behind the vehicle, Bosch explained. The European manufacturer has set up the sensor to put out a signal on the side mirror, whenever a vehicle approaches at speed from behind or is present in the blind spot.
When a driver continues to activate the turn signal with the intention of changing lanes, the lane-changing assistant gives out an additional acoustic and/or haptic warning, the company said. The MRR system is claimed to effectively provide information for other driver assistance systems including adaptive cruise control (ACC), cross-traffic alert system and predictive emergency braking systems. The compact design of the system allows it to be fit into smaller cars, as well. The MRR sensor is a bistatic multi-mode radar with four independent receiver channels and digital beam forming, and operates in the 76-77 GHz frequency band, Bosch said.
While the MRR rear system has an aperture angle of up to 150° and a range of up to 90 meters, the front-facing version has a +/-45° aperture angle. The front-facing variant can detect objects up to 160 meters away.
