Bosch Mobility
Now that there is already a wide range of assistance solutions available for cars driving on freeways and country roads, Bosch is also successfully developing systems for the essentially greater challenges of urban traffic.
Urban mobility means a high degree of complexity and therefore new dangers. It goes without saying that Bosch technology also integrates cyclists and pedestrians in particular. Their unpredictability often represents an increased risk – and they are at most risk in the event of an accident. Equipped with radar sensors and video cameras, these smart systems are capable of detecting other road users in complex situations, warning car drivers in time or even intervening autonomously in an emergency. This often means avoiding accidents in urban traffic or at least significantly reducing the severity of such accidents.
The significance of active safety systems has also been recognized by the independent test organization Euro NCAP (European New Car Assessment Programme): as of 2018, the Euro NCAP also includes emergency braking on cyclists in its assessment criteria. Pedestrian emergency braking systems have been integrated since 2016. This means that new car models can only achieve the maximum score of five stars if certain standards for avoiding accidents with pedestrians and cyclists are fulfilled.
of accidents involving cars and cyclists could be avoided if all cars were equipped with automatic emergency braking for cyclists (Bosch accident research).
automatic emergency braking can be initiated for pedestrians and cyclists.
is provided by the acoustic and optical door opening warning which warns of approaching road users when the car doors are opened.
Car assistance systems for active safety, such as automatic emergency braking for cyclists, pedestrian protection or door opening warning, are only as good as the components they rely on. Accordingly, Bosch is consistently further developing its surround sensors as well
as brake and steering systems. The result: production-ready key technology from a single source, which is ready for future assistance systems and automated driving functions.
Automatic emergency braking prevents collisions with cyclists.
Cyclists are often moving at a fairly brisk pace. Their behavior is often unpredictable, and their thin silhouettes can be difficult to make out through dense urban traffic. Surround sensors ease this situation by detecting cyclists alongside and ahead of the vehicle, monitoring speed, distance, and direction of travel to calculate the potential risk of an accident. In the case of an imminent collision, the system automatically brings the vehicle to a stop in order to avoid or at least reduce the severity of the accident. Estimations indicate that this could eliminate or at least reduce the severity of almost half of road accidents involving cyclists and cars.
The door opening warning provides an optical and acoustic warning about objects approaching from behind.
Fatigue, haste or stress can lead to driver or passenger inattentiveness. If the vehicle is parked longitudinally, the car door is opened without checking the side mirrors and looking over each shoulder and a cyclist approaches from behind at high speed, this can be very dangerous. Bosch’s door opening warning informs the passengers and mitigates the risk for cyclists.
By means of corner radar sensors mounted at the rear of the car, the system can pinpoint approaching road users such as cars, cyclists, scooters, and motorcyclists, precisely and in real time. Optical and acoustic signals warn drivers and passengers against opening the door. This way, the door opening warning minimizes the risk of an accident, avoids injuries to cyclists, and eliminates possible damage to vehicles.
The system detects pedestrians and initiates automatic emergency braking in the case of imminent danger.
Pedestrians are the most vulnerable road users, often overlooked and therefore particularly at risk. Using video and radar sensors, the predictive pedestrian protection system detects pedestrians that suddenly step out in front of vehicles and are in danger of being hit by them. If the driver does not react to the warning, the system can initiate an automatic emergency stop at speeds of up to 60 km/h. Depending on the configuration, this emergency stop can be effected without warning the driver beforehand. As a result, the predictive pedestrian protection system helps protect vulnerable road users and helps drivers avoid or at least mitigate the severity of collisions.
In March 2019, the European Parliament, Council and Commission reached a provisional political agreement on the revised General Safety Regulation.
As of 2022 additional safety technologies like the automatic emergency braking will become mandatory in new vehicle types in Europe.*
