Abstract

A visual display monitor of an information system of a motor vehicle is connected not only with the usual engine and vehicle instrumentation, but also with a variety of electrical equipments installed in the motor vehicle which the driver may want to activate and control from time to time. The picture screen of the monitor, preferably of the LCD, electro-luminescence or plasma type, is subdivided into a report region at the top and a region for interactive information such as instructions menus and operation results. All the functions that would otherwise be performed by individual buttons, knobs and switches of the various equipments installed in the vehicle may be simply performed by a series of easily designated choices. One input device has a ball control for directing a cursor on the screen of the monitor, a menu button and an entry button, and may be located on the steering wheel. While a particular equipment that has been selected is being controlled, the corresponding field of the monitor selected by the cursor has its light-to-dark contrast reversed, to indicate that the corresponding equipment is in the process of being adjusted or controlled. Another input device is combined with a telephone handset used for telephone calls and has a recessed alphanumeric keyboard in its back for more detailed entries into the system. The information system is built around a digital speech memory which not only provides telephone answering messages and the like but also makes possible audible outputs of the system through the ratio receiver'"'"'s loudspeaker so that the driver can be less dependent on visual outputs displayed on the monitor.

Claims

1. A digital speech memory for an information system of a motor vehicle equipped with a radio broadcast receiver, a traffic radio announcement decoder and a mobile telephone, and equipped also with at least two equipments of the group consisting of talk-in devices, CD players, navigation systems, alarm systems and vehicle test systems, in which information system speech signals are coded, for storage in a plurality of regions of a memory, at least by identification of data type, and comprising:

first memory regions (A, B, C), each coded for acceptable type of data, for presence of vacancy and for overwriteability at least in case of no vacancy, of which at least one (A) is non-overwriteable and allocated to data of warning type and at least two (B, C) are overwriteable, and respectively allocated to data from specific data source equipment (11, 13,

     15) related to radio communication, said at least one non-overwriteable region being erasable only by manual command;

at least one second memory region (D), coded for acceptable types of data, for the allocated portions of which are variable in capacity for storable information, and the overwriteable portions of which are likewise variable, said at least one second memory region being accessible for write-in by all data source equipment of said information system when said first memory regions have no vacancy present and being overwriteable in all cases in accordance with information already stored and information presented for storage and priorities related to said identifications of data type;

a memory region selector (3), having means (3A) for determining where and whether vacant portions and overwriteable portions of said memory regions are available for storage of presented information and for administering the use of vacant portions and overwriteable portions of said memory regions in accordance with a priority related to said identifications of data type, and

a switching matrix having a control input connected to said memory region selector (3) and a control input connected to a manually operable input (7), and having at least first input/output data ports respectively connected to said memory regions and second input/output data ports respectively connected to said radio broadcast receiver, traffic radio announcement decoder, mobile telephone and other said equipments of said group with which said motor vehicle is equipped, for at least producing selective temporary connections, each of a said first input/output port with a said second input/output port.

2. The digital speech memory of claim 1, which is constituted as a semi-conductor memory.

3. The digital speech memory of claim 1, wherein said information system of said vehicle includes a speech synthesizer and wherein said speech synthesizer is controllable through said digital speech memory.

4. The digital speech memory of claim 3, wherein said radio broadcast receiver of said motor vehicle information system contains a loud speaker and wherein means are provided for acoustic read-out by said loud speaker of information stored in said memory.

5. The digital speech memory of claim 1, wherein said information system of said vehicle includes a speech synthesizer (4'"'"') and wherein said speech synthesizer is controllable through said digital speech memory.

6. The digital speech memory of claim 1, wherein said first memory regions (A, B, C) are respectively provided for warning announcements, for a telephone answering announcement and for miscellaneous notations and that said at least one second memory region is made available for traffic announcements and additional notations, telephone calls and telephone announcements, among other data.

7. The digital speech memory of claim 6, wherein means are provided for storing, at least with said traffic announcements, the time and date of recording and wherein respective first memory regions (A, B, C) and respective portions of said at least one second memory region which are allocated for the respective data types of notations, telephone call and telephone announcement information are overwriteable only by data of the same type, whereas any portion of said first memory region which is allocated for traffic announcements and portions of said second memory region allocated for traffic announcements are conditionally overwriteable by data of all types, subject to a condition of overwriting which is dependent upon the time and date of recording of a traffic announcement.

8. The digital speech memory of claim 1, which is for an information system which contains data input means (7) and a visual display monitor (8) having means for display of action within said system responsive to control signals originating from said data input means (2) and wherein means are provided for display on said monitor of information of at least one data type currently elicited from said digital speech memory in response to said data input means (7).

9. The digital speech memory of claim 1, which is for an information system which contains data input means (7) and a visual display monitor (8) having means for display of action within said system responsive to control signals originating from said data input means (7) and wherein means are provided for display on said monitor of information of at least one data type currently elicited from said digital speech memory in response to said data input means (7).
