Abstract

A vehicular user hospitality system is provided for detecting a condition of a user, and for controlling operations of a vehicular devices autonomously in the manner most desired (or estimated to be desired) by the user. A content of an operation of a hospitality operation portion changes in accordance with a content of user biological characteristic information. Service (hospitality) effect for the user using a vehicle can be further optimized in accordance with a mental or physical condition of the user. Specifically, standard reference information about an operation control of a function specified from a function extraction matrix is extracted. A physical or mental condition reflected by separately obtained user biological characteristic information is added to this standard reference information. Accordingly, the operation content of the selected function can be optimized.
