Abstract
PURPOSE:To reduce the burden of a drive except during the maximum gear ratio by sounding an alarm only when preset criteria for time is exceeded instead of useless alarms at the high speed travel and acceleration. CONSTITUTION:The signals from an engine rotary sensor 2 and a car speed sensor 3 are waveform-treated and guided to an integrator circuits 7 and 11. An arithmetic cricuit 12 operates the gear shift position based on these signals and issues the signal A which corresponds to the shift position and the maximum gear position signal C. A reference voltage generator circuit 13 outputs the voltage V corresponding to the maximum speed that corresponds to the gear position and a compare circuit 14 issues an output O1 when the number of engine revolutions exceeds the maximum speed. An alarm is sounded after the time constant of the integrator circuit 7 by the actuation of an AND gate 18 except during the maximum gear position. As a result, the alarm at the high speed travel is controlled, the useless alarm during shift map is removed, and the burden of a driver is reduced.
