ABSTRACT:
In a speed alarm system for an automotive vehicle, a speed signal and a first command speed signal indicative of a first command speed are produced, and a speed width signal indicative of a predetermined speed width is produced. A value of the speed width signal is added to a value of the first command speed signal to produce a second command speed signal indicative of a second command speed. A first output signal is produced when a value of the speed signal exceeds the first command speed, and a second output signal is produced when a value of the speed signal exceeds the second command speed. First and second alarm sounds are generated in response to the first and second output signals for first and second predetermined alarm times respectively.
