Proximity warning unit for vehicles - is capable of automatic collision avoidance using required deceleration threshold and controlled braking

摘要

A proximity warning unit for vehicles has measurement and evaluation devices for vehicle speed, distance from defined vehicles or obstacles, and approach speed of other vehicles or obstacles. It is designed to present information to the driver enabling him to determine his need for intervention and to be suitable for automatic collision avoidance. The measured parameters are evaluated to produce a braking a deceleration requirement for collision avoidance and maintenance of separation. When the required deceleration exceeds a threshold which is preferably adjustable braking is automatically applied to restore tolerable proximity.
