PROBLEM TO BE SOLVED: To acquire later information when pieces of information are over lapped, and to prevent the failure of a hearing operation by a method wherein a storage means stores information regulated. from outside until the regulation of the provision of information is eliminated. SOLUTION: Until the regulation of the porvision of information by a regulation means is eliminated, a storage means stores information regulated from outside, and the regulated information can be read out from the storage means. That is to say, the provision of information (voice information) which is not required by a driver is suppressed or not output. In addition, only one piece of specific information is selected out of a plurality of pieces of voice information. The piece of voice information is selected on the basis of importance due to a relationship with a running condition. For example, the importance of NAVI information is high on a congested road (its value is '2'), and the importance is low (its value is '4') near a driver's home because a driver is familiar with its neighborhood. In addition, information (urgent information) whose importance value is '1" is always output, and information whose importance value is '4' is regarded as an object not to be output. |
