Abstract

A vehicle information display apparatus that shortens an activation waiting time is obtained. The vehicle information display apparatus includes a display unit that displays vehicle information utilized in a vehicle and a control unit that controls contents displayed on the display unit; the control unit makes display control for the vehicle information operate in a power-saving mode where functions are limited, when the trigger signal is detected, and makes the display control for the vehicle information operate in a normal mode where functions are not limited, when the engine has been started completely.

Claims

1. A vehicle information display apparatus comprising:

a display unit that displays vehicle information utilized in a vehicle; and

a control unit that controls contents displayed on the display unit, wherein in a vehicle information display apparatus that is activated by a trigger signal to be detected before a vehicle engine is started, the control unit makes display control for the vehicle information operate in a power-saving mode where functions are limited, when the trigger signal is detected, and makes the display control for the vehicle information operate in a normal mode where functions are not limited, when the engine has been started completely.

2. The vehicle information display apparatus according to claim 1, wherein in the power-saving mode, the display unit displays vehicle information that can be displayed in the power-saving mode.

3. The vehicle information display apparatus according to claim 1, wherein a determination condition, based on which the control unit determines that the engine has been started completely, is the fact that the rotation speed of the engine exceeds a predetermined value.

4. The vehicle information display apparatus according to claim 2, wherein a determination condition, based on which the control unit determines that the engine has been started completely, is the fact that the rotation speed of the engine exceeds a predetermined value.

5. The vehicle information display apparatus according to claim 1, wherein a determination condition, based on which the control unit determines that the engine has been started completely, is the difference between a voltage value of a battery, mounted in the vehicle, at a time before the engine is started and a voltage value of the battery at a time after the engine has been started.

6. The vehicle information display apparatus according to claim 2, wherein a determination condition, based on which the control unit determines that the engine has been started completely, is the difference between a voltage value of a battery, mounted in the vehicle, at a time before the engine is started and a voltage value of the battery at a time after the engine has been started.

7. The vehicle information display apparatus according to claim 3, wherein a determination condition, based on which the control unit determines that the engine has been started completely, is the fact that the determination condition continues for a predetermined time.

8. The vehicle information display apparatus according to claim 4, wherein a determination condition, based on which the control unit determines that the engine has been started completely, is the fact that the determination condition continues for a predetermined time.

9. The vehicle information display apparatus according to claim 5, wherein a determination condition, based on which the control unit determines that the engine has been started completely, is the fact that the determination condition continues for a predetermined time.

10. The vehicle information display apparatus according to claim 6, wherein a determination condition, based on which the control unit determines that the engine has been started completely, is the fact that the determination condition continues for a predetermined time.

11. The vehicle information display apparatus according to claim 1, wherein the control unit cancels the power-saving mode before the engine has been started.

12. The vehicle information display apparatus according to claim 2, wherein the control unit (114) cancels the power-saving mode before the engine has been started.

13. The vehicle information display apparatus according to claim 1, wherein when the vehicle information display apparatus is working in the power-saving mode and the voltage across the battery mounted in the vehicle is the same as or lower than a predetermined value, the control unit can end the power-saving mode.

14. The vehicle information display apparatus according to claim 2, wherein when the vehicle information display apparatus is working in the power-saving mode and the voltage across the battery mounted in the vehicle is the same as or lower than a predetermined value, the control unit can end the power-saving mode.
