摘要:
A speech recognition system for an automotive vehicle which can record or recognize spoken instruction phrases reliably even when engine noise increases high within the passenger compartment. When the engine begins to operate, the gain of an amplifier of a speech input section or the threshold level of a voice detector is so switched as to reduce the sensitivity to spoken instructions. As a result, the driver must necessarily utter a spoken instruction in a louder voice and thus the proportion of noise level to spoken instruction signal level is reduced. The system according to the present invention comprises engine operation detecting means, an analog switch, two amplifiers or two multipliers, etc. in addition to the conventional speech recognizer.

A speech recognition and actuator system for auto device control includes a recognition switch which when operated a first time activates the system to accept a spoken command, and if operated a second time within a predetermined interval T1 (approximately 2 seconds) stops the actuation and awaits a new command. Additional timers provide interval T2 for a stop command, and T3 for enabling the speech recognizer. The system may also include a reset switch when operated returns the actuated device to its original state.
摘要:
A spoken-instruction controlled system for an automotive vehicle by which a single actuator can be activated repeatedly or a plurality of actuators can be activated sequentially by repeatedly depressing a recognition switch within a predetermined time period after a spoken instruction corresponding to the single actuator or actuators has been recognized by a speech recognizer. Therefore, it is possible to activate an actuator repeatedly or actuators sequentially without uttering the same spoken instruction repeatedly. The spoken-instruction controlled system according to the present invention comprises a two-circuit analog switch, at least one analog switch, at least one retriggerable timer unit, an AND gate, an OR gate, a shift register, etc., in addition to a speech recognizer.

A system and method for communicating data between a master station and a plurality of control units applicable to an automotive vehicle are disclosed in which if an echoback communication in response to a control command is not received by the master station from the selected control unit within a predetermined period of time upon issuance of a continue command or a diagnostic execution command, the controlled state of the electronic control unit is released. Furthermore, to effectively diagnose the control operation of one of the control units interactively with the operation of other control units, an interrupt command may be issued while the selected control unit continues the predetermined control operation, and the remaining control units are then initialized. A different control unit may then be selected and set to a controlled state. While the second selected control unit is in the controlled state an interrupt command may be issued, thus maintaining the second selected control unit in a controlled state. A resume command is then issued to resume communication with the first selected control unit which has been maintained in a controlled state, so that the control operation of a control unit which is affected by the operation of any one of the other control units can appropriately be diagnosed.

The vehicle seat and the steering wheel are shifted to the drive position when the door is open and to the getting in/out position when the door is opened, as long as the ignition key is inserted into the key cylinder without shifting the key at the accessory and ignition positions. Further, the seat and wheel are shifted to the drive position when the key is inserted into the key cylinder and to the getting in/out position when the key is removed therefrom, as long as the key is not shifted at the accessory and ignition positions. Further, the seat and wheel are shifted to the drive position when the key is shifted to the ignition position, as long as the key is inserted into the key cylinder and shifted at the accessory position. Furthermore, the seat and wheel are shifted to the drive position under door-closed condition and to the getting in/out position under door-open condition, when the key is shifted from the accessory position to the lock position, as long as the key is inserted into the key cylinder and not shifted at the ignition position.

A time-division multiplexing data transmission/reception system applicable to a vehicle is disclosed in which a multiplexing synchronizer, for generating and outputting a pulse train signal to a single data transmission line, is connected between a power supply and a data transmission line. The pulse train signal has a master synchronization interval defined by disconnecting the power supply from the signal transmission line for a first predetermined time width and has a plurality of communication channel intervals, each communication channel interval being defined by connecting the power supply to the signal transmission line for a second predetermined time width followed by disconnecting the power supply from the signal transmission line for a third predetermined width. A transmitter transmits data, having one of two different pulse widths during a specified communication channel interval, to the signal transmission line. Then, a receiver receives data whose pulse width is changed according to the input state of an external apparatus which is connected to the transmitter and outputs the data to an external load thereof so that the load is actuated or deactuated.

A speech recognition system for an automotive vehicle enables desired reference spoken instruction phrases to be easily re-recorded by repeatedly depressing a manual switch arrangement that commands skipping. Each activation of the switch shifts the system from a ready state for recording the current spoken instruction to a ready state for recording a succeeding spoken instruction. By repeatedly activating the skip switch ready state for re-recording any given spoken instruction is reached. In one embodiment, a separate skip switch is provided. In a second embodiment, logic circuitry responds to simultaneous activation of record and recognition switches to command skipping.

In a speech recognition and control system for an automobile, the microphone preamplifier gain is made inversely proportional to the background sound noise level. Noise level is determined by averaging the microphone output for 100 milliseconds after the recognition switch is closed, before speech.

A speech recognition system includes speech presence detection which uses a first level threshold of ambient noise/silence above which speech start is decided for a signal. Speech end is decided when the signal falls to a second threshold equal to the first, unless a predetermined time interval of speech is exceeded after start, causing a corrected second threshold to be calculated and used.
