Abstract
Abstract A vehicle safety system for detecting the presence of objects in the vicinity of the vehicle and for producing an indication upon the detection of the objects. The system comprises a front sensor and rear sensor each of which includes a Doppler radar and side sensors which include proximity radars. The system also includes a vehicle velocity sensor which senses the velocity of the vehicle and produces an output indicative thereof. A signal processing unit receives the outputs of the front and rear sensors and the vehicle velocity sensor and produces an output which is indicative of the vehicle''s capability of stopping prior to colliding with an object detected in front of the vehicle, and also produces an output indicative of the range and closing speed of an object detected to the rear of the vehicle. An indicator is coupled to the signal processing unit and produces a signal indicative of the signal processor output, and signals indicative of the location of an object alongside the vehicle. The output of the processing unit may also be applied to the vehicle brake and accelerator controls for slowing down the vehicle if the operator does not respond properly to a warning signal generated by the indicator.
