Driver Assistance Systems

Today's drivers have a wide range of driver assistance solutions at their disposal, making travel on highways and main roads considerably safer and more comfortable. Now, Bosch has turned its attention to developing systems that cater to the significantly bigger challenges posed by city driving. Urban mobility is highly complex and brings with it new risks. Naturally, Bosch’s new technologies pay particular attention to cyclists and pedestrians as fellow road users. These groups are unpredictable and so present more of a risk – and they are often the ones most vulnerable in the case of a traffic accident.

Bosch’s smart, new systems are equipped with radar sensors and video cameras, allowing them to detect these road users even in complex traffic situations. The system is ablel to warn the driver and even intervene if necessary. This is achieved in defined situations through the communication and interaction of a variety of components. The end result is the avoidance, or at least a reduction, in the number of accidents in city traffic. These pioneering technologies work to the benefit of all road users – with more safety and convenience for drivers, and increased protection for cyclists and pedestrians.

Calculating the incalculable:
Automatic emergency braking on cyclists

Cyclists are usually moving at a fairly brisk pace. Their behavior is often unpredictable, and their thin silhouettes can be difficult to make out through the 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 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.

Cyclist approaching, best keep the door shut

Cyclist approaching parking cars

When exiting a street-parked car, unseen cyclists pose a daily risk for city drivers and their passengers; all you need is a cyclist coming up quickly as you open the door. Bosch’s car exit warning mitigates this risk.

By means of rear mid-range radar sensors, the system can monitor hazards such as cars, cyclists, scooters, and motorcylists within a 20-meter (~65-foot) radius, pinpointing them in real time. Optical and acoustic signals provide a warning that prevents drivers and their passengers from opening the door. This technology aims to eliminate the risk of an accident, reduce injuries to cyclists, and minimize damage to vehicles.

Predictive pedestrian protection system
with built-in emergency stop

Pedestrian crossing a street

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. If the driver does not react to the warning, the system can initiate an automatic emergency stop at speeds of up to 60 kph (~37 mph). Depending on the configuration, this emergency stop can be activated 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 road accidents.
