Electronic safety device for motor vehicles - has radar whose pulse width is affected by driving speed and distance of vehicle in front

摘要

The safety device informs the driver about the distance and relative speed of a vehicle in front of him. It has an antenna transmitting in front radar station operating with short pulses with high keying ratio and a signalling device with lamps informing the driver about the state of all important objects in different distance ranges. The radar pulse width is affected by the driving speed, and is adjusted to the corresp. safety distance.
