1. An attention attracting system comprising:
HMI devices that are mounted on a subject vehicle; and
an attention attracting device configured to transmit, to a driver, a possibility of contact between the subject vehicle and an object through the HMI devices, wherein
the HMI devices include a tactile HMI device, an auditory HMI device, and a visual HMI device, the tactile HMI device providing a stimulus to a tactile perception of the driver, the auditory HMI device outputting sound to the driver, the sound serving as an auditory stimulus, the visual HMI device transmitting visual information to the driver,
the attention attracting device includes
a risk identification section configured to identify a risk position and a risk level, the risk position being a position having a strong possibility of contact occurring between the subject vehicle and an object in an environment surrounding the subject vehicle, the risk level being a degree of the possibility of the contact occurring at the risk position, and
a transmission section configured to transmit the risk position and the risk level to the driver, and
the transmission section
provides a tactile stimulus or an auditory stimulus to the driver through the tactile HMI device or the auditory HMI device at a remarkableness level corresponding to strength of the possibility of the contact indicated by the risk level, and
transmits visual information to the driver through the visual HMI device, the visual information indicating a direction of the risk position viewed from the driver,
the attention attracting device includes
an attention state determination section configured to determine whether or not the driver is in an attention-distracted state,
a line-of-sight determination section configured to determine whether or not the driver has a line of sight in the direction of the risk position, and
an evasion determination section configured to determine whether or not the driver is performing evasive steering that is an evasive action for evading the contact which is possible contact, and
the transmission section
identifies a state of the driver as any of a first state, a second state, a third state, and a fourth state on a basis of results of determinations by the attention state determination section, the line-of-sight determination section, and the evasion determination section,
the first state being a state in which the driver is not in the attention-distracted state, has the line of sight in the direction of the risk position, and is performing the evasive steering,
the second state being a state in which the driver is not in the attention-distracted state, has the line of sight in the direction of the risk position, and is not performing the evasive steering,
the third state being a state in which the driver is not in the attention-distracted state and does not have the line of sight in the direction of the risk position,
the fourth state being a state in which the driver is in the attention-distracted state, and
provides the tactile stimulus or the auditory stimulus to the driver by using the tactile HMI device or the auditory HMI device unless the state of the driver is the first state.
