Collision alarm system for automotive vehicle

A collision alarm system for an automotive vehicle comprising:

• object identifying means for monitoring a moving condition of an object present ahead of a system vehicle equipped with this system, said object identifying means identifying the object as a moving object or an unidentified object other than the moving object and providing a signal indicative thereof the signal having a first state indicative of a determined stationary object, and a second different state indicative of a determined moving object;
• moving object alarm means, responsive to the signal from said object identifying means, for issuing an alarm when a distance between the object identified by said object identifying means as the moving object and the system vehicle falls within a given warning distance;
• and
• alarm inhibiting means operatively connected to said moving object alarm means for inhibiting said moving object alarm means from issuing the alarm for a delay period of time after the object which has been identified by said object identifying means as the unidentified object, is identified as the moving object.

A collision alarm system for an automotive vehicle comprising:

• object determining means for determining whether an object falling within a given detection zone is a stationary object or a moving object and for providing a signal indicative thereof the signal having a first state indicative of a determined stationary object, and a second different state indicative of a determined moving object;
• stationary object alarm means, responsive to the signal from said object determining means, for issuing an alarm when a distance between the object determined by said object determining means as the stationary object and said system vehicle equipped with this system falls within a given stationary object warning distance, said given stationary object warning distance being determined based on a preselected traveling condition of the system vehicle;
• moving object alarm means, responsive to the signal from said object determining means, for issuing an alarm when a distance between the object determined by said object determining means as the moving object and the system vehicle falls within a given moving object warning distance, said given stationary object warning distance being increased at a first rate in proportion to a speed of the system vehicle within a predetermined lower speed range and at a second rate smaller than the first rate in proportion to the speed of the system vehicle within a predetermined higher speed range;
• and
• alarm inhibiting means operatively connected to said moving object alarm means for inhibiting said moving object alarm means from issuing the alarm for a delay period of time after the object falling within the given detection zone which has been determined by said object determining means as the stationary object, is determined as the moving object.
