Abstract

To avoid pinched fingers, a verbal "Stop Window" command causes a stop and momentary reversal of window motion. A spoken-instruction controlled system for an automotive vehicle which can stop a moving device such as a door window closing device after having driven it reversely for a fixed period when a spoken instruction is inputted thereto through a microphone. In the system according to the present invention, even if there exists a time delay from when the driver utters the spoken instruction to when the device stops perfectly, it is possible to stop the device at or before a position at which the driver utters the spoken instruction. The system according to the present invention comprises at least one motor reversing controller and a timer unit, in addition to the conventional spoken-instruction controller including at least one switch, at least one motor stop controller and a speech recognizer.

Dependent claims

A spoken-instruction controlled system for an automotive vehicle which can stop at least one moving device being driven by a motor in either of two opposite directions in response to a predetermined spoken instruction inputted through a microphone, which comprises:

(a) at least one switch for outputting either of two kinds of signals from two output terminals thereof, separately, and for driving the at least one device in either of two opposite directions when set to either of two set-positions, respectively;
(b) means for detecting one of the two set-positions in response to either of two signals and outputting signals corresponding thereto;
(c) a speech recognizer for outputting a command signal e.sub.1 in response to the predetermined spoken instruction inputted through the microphone, said speech recognizer being activated by either of two signals from said means for detecting one of the two set-positions, independently;
(d) a timer unit for outputting a command signal e.sub.2 a predetermined time period after the signal e.sub.1 has been applied thereto from said speech recognizer;
(e) at least one means for reversing the motor for outputting a first power signal to drive the motor in one direction in response to one signal outputted from said switch when said switch is set to one set-position and a second power signal to drive the motor in the other opposite direction in response to the other signal outputted from said switch when said switch is set to the other set-position, at least one of the first and second power signals being switched in response to the signal e.sub.1 from said speech recognizer in order to drive the motor reversely;
and
(f) at least one means for stopping the motor for cutting off either of the first and second power signals outputted from said means for reversing the motor in response to the signal e.sub.2 outputted from said timer unit in order to stop the motor.
