1. An anti-collision radar system provided with circuitry for monitoring a driver'"'"'s ability to safely control a vehicle, comprising:
- (a) a radar which detects the possibility of collision of the vehicle against an obstacle ahead for producing a collision imminence signal with which an alarm and/or a brake actuator is energized;
(b) reference period providing means;
(c) counting means connected to said reference period providing means for producing at least one output signal when the number of the collision imminence signals reaches at least one predetermined value during at least one reference period which is provided by said reference period providing means; and
(d) alerting means connected to said counting means for alerting the vehicle driver upon presence of said output signal of said counting means.

Abstract
A counter is provided for detecting the frequency of generation of collision imminence signals produced in a conventional type of anti-collision radar system for a vehicle. An odometer and/or a clock pulse generator is connected to the counter for applying a reference counting period so that the counter is utilized for generating a signal with which an alerting device which is independent from that of the radar system, is energized when the frequency reaches a predetermined value during the reference counting period.
