Bottleneck assistant - BMW wants to make construction sites safer
Subscriptions & booklets
The system is based on the Lane Keeping Assist is already available and is intended to help the driver, for example in motorway construction sites, to correctly assess narrow passages and to keep the course precisely when driving through.
System measures bottleneck
To do this, the electronics look ahead with a laser scanner and now uses ultrasonic sensors that estimate the lateral distance to obstacles such as crash barriers or other vehicles. An overall picture is created from the data obtained in this way, which is shown to the driver's lateral distance with circular symbols directly into the head-up display. At the same time, before overtaking, the assistant checks whether the width of the second lane is sufficient to pass. If the lateral minimum distance is not reached, the system sends a warning signal and transmits a steering impulse to the steering wheel.
Assistant for medical emergencies
Another new addition to the BMW development program is an assistance system for medical emergencies that is being tested together with the Charité University Clinic in Berlin: If the emergency stop assistant detects that the driver is weak, the car switches to an automatic driving mode. Then the electronics switch on the hazard warning lights and maneuver the car in a controlled manner to the right side of the road in order to bring it to a stop. At the same time, the system makes an automatic emergency call.
Although both new assistance systems use sensors and software of current series functions. But whether and when the electronic helpers can be used for bottlenecks and medical emergencies, could be B MW still open.
