The control unit 1 inputs information from the user identification unit 4 and the input unit 5 and various vehicle information of the vehicle such as the vehicle running state, and performs a display unit 2 and an external output unit by predetermined arithmetic processing based on these inputs. 3 is configured to control.

  For example, a liquid crystal display panel capable of displaying an image can be applied to the display unit 2, and a display output is performed based on a control signal from the control unit 1. In this case, the display means 2 is configured so that information such as a measured value such as an integrated travel distance of the vehicular meter, an outside air temperature, and various set values can be displayed by switching screens.

  The external output means 3 can be applied with an external terminal for writing information in the vehicle meter to an external storage medium. For example, information used for the calculation of the control means 1 via a memory portable to the user outside the vehicle. Can be taken out. Therefore, the user can easily secondary use information from the vehicle using a personal computer or the like. Note that it is also possible to use a short-range wireless communication device using infrared rays or radio waves as the external output means 3.

  The user identification unit 4 identifies a user by using personal identification information stored in advance in a storage medium such as a magnetic card or an IC chip, or personal identification information by a communication unit such as a mobile phone, and identifies the use The identification information of the person is output to the control means 1. In addition, the user identification means 4 can also be provided in the vehicle meter A. The user identification unit 4 can be substituted by performing image identification such as face recognition or fingerprint recognition. For example, the user is imaged by the imaging unit and compared with information of a user registered in advance. Thus, the user of the vehicle can be specified.

  The input means 5 can be applied with a switch or the like and outputs an input signal to the control means 1 in accordance with a pressing operation by the user. It is also possible to apply a voice input device as the input means 5 and use the voice of the user as an interface to the vehicle instrument.

  Next, processing relating to the display of the usage ratio by the control means 1 will be described.
