Spoken-instruction controlled system for an automotive vehicle
First Claim
1. 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 e1 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 e2 a predetermined time period after the signal e1 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 e1 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 e2 outputted from said timer unit in order to stop the motor.

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.

9. In a spoken-instruction controlled system for an automotive vehicle which can stop at least one moving device being driven by a motor, in response to an ON-signal from at least one switch, in either of two opposite directions, when a predetermined spoken instruction is inputted through a microphone, the method of first driving the device reversely and next stopping it after a predetermined period of time, which comprises the following steps of:
-
(a) finding one of the switches currently being depressed and one of set-positions of the depressed switch; (b) actuating a device corresponding to the depressed switch in one direction corresponding to the set position of the depressed switch; (c) inputting a spoken instruction through the microphone; (d) detecting the inputted spoken instruction; (e) setting a timer in response to the detection signal of the spoken instruction; (f) reversing the device in the opposite direction; (g) comparing the time period from when the device is reversed with a fixed period set by the timer; and (h) stopping the device currently moving reversely when the fixed period has elapsed.
