Abstract

Most of on-vehicle DSRC apparatus are mounted on a dashboard of a vehicle and downsized not to hinder vision. Therefore the number of switches disposed on a panel is limited, while increase in number of functions is expected. Moreover, since an on-vehicle DSRC apparatus is operated while driving, a function key method adapted to operate keys visually is not applicable. Accordingly, an apparatus capable of performing multiple functions, in which can be assigned to one switch and operation can be performed without viewing, is demanded. A press button is operated to punch Morse code. Different functions are preliminarily allotted to respective punching patterns. A switch determination section stores the allotted functions, analyzes a press pattern and determines a function to be allotted. One switch serves multiple functions including sound volume setting, history confirmation, and on-vehicle apparatus identification number, achieving a small size on-vehicle DSRC apparatus at reasonable price.

Claims (33)

1. An on-vehicle DSRC apparatus for use in a dedicated short-range communication system of intelligent transport systems, and which is mounted on a vehicle traveling on a road, the DSRC on-vehicle apparatus comprising:

a radio communication section carrying out a communication with information radio equipment provided on a roadside;

a sound volume setting section setting a sound volume of a speaker that announces information with a voice;

a first switch of a press button type that is located on a panel front face and has said sound volume setting function; and

a switch determination section that detects a connection/disconnection of said first switch with an elapse of time and recognizes said connection/disconnection as a pattern in the course of the time, compares said pattern with a plurality of patterns having been preliminarily stored, and allots a function having been assigned to said pattern with which a current pattern is coincident to said first switch on condition that the current pattern is coincident with any of said plurality of patterns having been preliminarily stored.

2. The DSRC on-vehicle apparatus according to claim 1 , further comprising a card read section reading a card that stores electronic information and including a card switch that operates in response to said card being inserted or pulled out; and

a switch total determination section changing a function, which said switch determination section allots, depending on ON/OFF of said card switch.

3. An on-vehicle DSRC apparatus for use in a dedicated short-range communication system of intelligent transport systems, and which is mounted on a vehicle traveling on a road, the DSRC on-vehicle apparatus comprising:

a radio communication section carrying out a communication with information radio equipment provided on a roadside;

a sound volume setting section setting a sound volume of a speaker that announces information with a voice;

a first switch of a press button type that is located on a panel front face and has said sound volume setting function;

a card read section reading a card that stores electronic information and including a card switch that operates in response to said card being inserted or pulled out;

a card determination section that detects a connection/disconnection of said card switch with an elapse of time and recognizes said connection/disconnection as a pattern in the course of the time, compares said pattern with a plurality of patterns having been preliminarily stored, and allots a function having been assigned to said pattern with which the current pattern is coincident to said card switch on condition that the current pattern is coincident with any of said plurality of patterns having been preliminarily stored; and

a switch total determination section changing a function, which said card determination section allots, depending on ON/OFF of said first switch.

4. An on-vehicle DSRC apparatus for use in a dedicated short-range communication system of intelligent transport systems, and which is mounted on a vehicle traveling on a road, the DSRC on-vehicle apparatus comprising:

a radio communication section carrying out a communication with information radio equipment provided on a roadside;

a sound volume setting section setting a sound volume of a speaker that announces information with a voice;

a first switch of a press button type that is located on a panel front face and has said sound volume setting function; and

a switch determination section that detects connection/disconnection of said first switch with an elapse of time and recognizes said connection/disconnection as a contact pattern in the course of the time, compares said contact pattern with a plurality of said contact patterns having been preliminarily stored, and allots a function having been assigned to said contact pattern with which the current pattern is coincident to said first switch on condition that the current pattern is coincident with any of said plurality of contact patterns having been preliminarily stored;

a card read section reading a card that stores an electronic information and including a card switch that operates in response to said card being inserted or pulled out;

a card determination section that detects connection/disconnection situation of said card switch with an elapse of time and recognizes said connection/disconnection as a contact pattern in the course of the time, compares said contact pattern with a plurality of said contact patterns having been preliminarily stored, and allots a function having been assigned to said contact pattern with which the current pattern is coincident to said card switch on condition that the current pattern is coincident with any of said plurality of contact patterns having been preliminarily stored; and

a switch total determination section assigning a function on condition that there is coincidence between a function allotted by said switch determination section and a function allotted by said card switch determination section.

5. The DSRC on-vehicle apparatus according to claim 1 , further comprising a first timer that sets a length of time period during which a function that said switch determination section allots is effective.

6. The DSRC on-vehicle apparatus according to claim 2 , further comprising a first timer that sets a length of time period during which a function that said switch total determination section allots is effective.

7. The DSRC on-vehicle apparatus according to claim 3 , further comprising a first timer that sets a length of time period during which a function that said switch total determination section allots is effective.

8. The DSRC on-vehicle apparatus according to claim 4 , further comprising a first timer that sets a length of time period during which a function said switch total determination section allots is effective.

9. The DSRC on-vehicle apparatus according to claim 1 , further comprising a sound volume adjustment section storing a vocalization content for causing a sound source section that announces said volume level with voice from said speaker to make a voice relevant to a sound volume thereof when said sound volume setting function is assigned to said first switch.

10. The DSRC on-vehicle apparatus according to claim 3 , further comprising a sound volume adjustment section storing a vocalization content for causing a sound source section that announces said volume level with voice from said speaker to make a voice relevant to a sound volume thereof when said sound volume setting function is assigned to said first switch or said card switch.

11. The DSRC on-vehicle apparatus according to claim 4 , further comprising a sound volume adjustment section storing a vocalization content for causing a sound source section that announces said volume level with voice from said speaker to make a voice relevant to a sound volume thereof when said sound volume setting function is assigned to said first switch or said card switch.

12. The DSRC on-vehicle apparatus according to claim 8 , further comprising a second timer for determining a sound volume set value.

13. The DSRC on-vehicle apparatus according to claim 10 , further comprising a second timer for determining a sound volume set value.

14. The DSRC on-vehicle apparatus according to claim 11 , further comprising a second timer for determining a sound volume set value.

15. The DSRC on-vehicle apparatus according to claim 1 , wherein at least one of said patterns is a pattern corresponding to a Morse code.
