Abstract

A vehicle information transmitting apparatus transmits information to a driver by optical stimulus, and determines whether or not to change a mode of the stimulus on the basis of at least one of information about the driver, an operation input, and a behavior of a vehicle, the information about the driver, the operation input, and the behavior being obtained after the transmission of the information. The vehicle information transmitting apparatus may change the mode of the stimulus when determining that the information is not considered by the driver. Further, the vehicle information transmitting apparatus may change the mode of the stimulus when determining that a cause that the information is not considered resides in the mode of the stimulus.

Claims

1. A vehicle information transmitting apparatus that transmits information to a driver by optical stimulus and changes a mode of the stimulus when it is determined that the information is not considered by the driver on the basis of at least one of information about the driver, an operation input, and a behavior of a vehicle, the information about the driver, the operation input, and the behavior being obtained after the transmission of the information.

2. The vehicle information transmitting apparatus according to claim 1,

wherein it is determined that the information is not considered by the driver on the basis of the degree of correlation between the behavior of the vehicle that is supposed on the basis of the information transmitted to the driver and an actual behavior of the vehicle that is obtained after the transmission of the information.

4. The vehicle information transmitting apparatus according to claim 1,

wherein the mode of the stimulus is changed when it is determined that a cause that the information is not considered by the driver resides in the mode of the stimulus.

5. The vehicle information transmitting apparatus according to claim 1,

wherein it is determined that the information is not considered by the driver when at least one of the operation input and the behavior of the vehicle obtained after the transmission of the information is not based on the information transmitted to the driver.

6. The vehicle information transmitting apparatus according to claim 4,

wherein it is confirmed whether or not the information continues to be transmitted to the driver by the stimulus when it is not determined that a cause that the information is not considered by the driver resides in the mode of the stimulus.

7. The vehicle information transmitting apparatus according to claim 4,

wherein a correspondence between the mode of the stimulus and the determination of whether or not information transmitted by the stimulus of the mode is considered by the driver is stored, and it is determined whether or not a cause that the information is not considered by the driver resides in the mode of the stimulus on the basis of the stored correspondence.

8. The vehicle information transmitting apparatus according to claim 1,

wherein the mode of the stimulus includes at least one of the brightness of the light, the color of the light, the size of the light to be projected, the shape of the light to be projected, the blinking cycle of the light, the gradient of the change of the brightness of the light, and the timing of the stimulus.

9. The vehicle information transmitting apparatus according to claim 6,

wherein a correspondence between the mode of the stimulus and the determination of whether or not information transmitted by the stimulus of the mode is considered by the driver is stored, and it is determined whether or not a cause that the information is not considered by the driver resides in the mode of the stimulus on the basis of the stored correspondence.
