Abstract
A voice warning system for an automotive vehicle such that warning information is first indicated to the driver in voice form when car-radio sound volume is reduced, and next in alarm sound form, without reducing the car-radio sound volume, until the driver takes a proper action. The system thus improved comprises a discriminator having a memory, a coincidence counter, a gate, AND circuits, and OR circuits, and an alarm generator, in addition to sensors and a voice output unit.
Claims6
A voice warning system for an automotive vehicle, said system comprising:
- (a) at least one sensor for periodically detecting various signals indicative of various vehicle operating conditions;
- (b) at least one vehicle operating-condition presetting device for presetting various signals indicative of various preset vehicle operating-conditions;
- (c) comparator means responsive to signals developed by said at least one of said sensors and said at least one of said vehicle operating-condition presetting devices for developing voice information control signals when said signals applied to said comparator means are unequal to each other;
- (d) discriminator means responsive to said comparator means for detecting variation in one of the control signals from said comparator means, and for developing (1) the control signal when the control signal varies and (2) an alarm signal when the control signal does not vary after the control signal has once been developed by said comparator means;
- (e) a voice selector responsive to the control signal of said discriminator means for selecting one of a plurality of designation signals stored therein;
- (f) a voice output unit responsive to said alarm signal of said discriminator means for producing an alarm sound;
- whereby warning information is first supplied to the driver in voice-form and then in alarm sound form if the voice warning information is not responded to.
In an automotive vehicle, a voice warning system comprising:
- sensor means for detecting various vehicle operating conditions;
- preset means having stored therein various preset vehicle operating conditions;
- comparator means responsive to said sensor means and said preset means for generating a control depending upon relative values of corresponding signals developed by said sensor means and said preset means;
- discriminator means responsive to said comparator means for detecting variation of said control signal and for developing (1) said control signal upon variation of said control signal following generation thereof from said comparator means and (2) an alarm signal upon non-variation of said control signal following generation thereof by said comparator means;
- means responsive to said control signal of said discriminator means for generating a voice warning signal;
- and
- means responsive to said alarm signal for thereafter producing an alarm sound.
