Vehicle alert apparatus
A vehicle alert apparatus includes: a drowse detector that detects drowse of a driver; an inattention detector that detects inattention of the driver; a vehicle speed detector that detects the vehicle speed; a notification portion that executes alert for the driver; and an alert controller that controls the alert executed by the notification portion based on a detection result of the drowse of the driver, a detection result of the inattention of the driver, or a detection result of the vehicle speed.
1. A vehicle alert apparatus comprising:
a drowse detector configured to detect drowse of a driver;
an inattentiveness detector configured to detect inattentiveness of the driver;
a vehicle speed detector configured to detect a vehicle speed;
a notification portion configured to execute an alert for the driver; and
an alert controller configured to control an execution of the alert executed by the notification portion based on a detection result of the drowse of the driver, a detection result of the inattentiveness of the driver, or the detection result of the vehicle speed,
wherein:
the alert controller is configured to control the alert in accordance with a determination level for the detection result of the vehicle speed;
the determination level is sectioned by a threshold value of the vehicle speed; and
in a case where the vehicle speed is equal to or lower than the threshold value, the alert controller is configured to cause the notification portion to execute the alert when the drowse of the driver is detected, and cause the notification portion not to execute the alert even when the inattentiveness of the driver is detected, wherein
the threshold value is changeable by the driver,
the vehicle alert apparatus further comprises an input portion through which the driver inputs information regarding troublesomeness with the alert,
the alert controller is further configured to change the threshold value based on the information input by the driver through the input portion,
the input portion is further configured to ask the driver as to whether the alert was troublesome at the end of driving, and
the driver inputs the information by answering to the input portion.
2. The vehicle alert apparatus according to claim 1 , wherein: in a case where the vehicle speed is higher than the threshold value, the alert controller is configured to cause the notification portion to execute the alert when the drowse of the driver is detected or when the inattentiveness of the driver is detected.
3. The vehicle alert apparatus according to claim 1 , wherein: in a case where the vehicle speed is equal to zero or close to zero, the alert controller is configured to cause the notification portion not to execute the alert even when the drowse of the driver is detected or even when the inattentiveness of the driver is detected.
4. The vehicle alert apparatus according to claim 1 , wherein: the alert includes alert for the drowse and alert for the inattentiveness;
the alert for the drowse or the alert for the inattentiveness is executed based on the detection result of the drowse, the detection result of the inattentiveness, and the detection result of the vehicle speed; and
in the case where the vehicle speed is equal to or lower than the threshold value, the alert controller causes the notification portion to execute the alert of the drowse when the drowse of the driver is detected, and causes the notification portion not to execute the alert of the inattentiveness even when the inattentiveness of the driver is detected.
5. The vehicle alert apparatus according to claim 1 , wherein the alert controller is further configured to decrease the threshold value when the driver consecutively answers to the input portion predetermined times that the alert was not troublesome.
6. A vehicle alert apparatus comprising:
one or more processors; and
a memory coupled to the one or more processors and storing program instructions that when executed by the one or more processors cause the one or more processors to at least:
detect drowse of a driver;
detect inattentiveness of the driver;
detect a vehicle speed;
execute an alert for the driver;
control execution of the alert executed based on a detection result of the drowse of the driver, a detection result of the inattentiveness of the driver, or the detection result of the vehicle speed; and
control the alert in accordance with a determination level for the detection result of the vehicle speed,
wherein:
the determination level is sectioned by a threshold value of the vehicle speed; and
in a case where the vehicle speed is equal to or lower than the threshold value, the one or more processors are configured to execute the alert when the drowse of the driver is detected, and are configured not to execute the alert even when the inattentiveness of the driver is detected, wherein
the threshold value is changeable by the driver,
the vehicle alert apparatus further comprises an input portion through which the driver inputs information regarding troublesomeness with the alert,
the one or more processors are further programmed to change the threshold value based on the information input by the driver through the input portion,
the input portion is further configured to ask the driver as to whether the alert was troublesome at the end of driving, and
the driver inputs the information by answering to the input portion.
7. The vehicle alert apparatus according to claim 6 , wherein:
the alert includes alert for the drowse and alert for the inattentiveness;
the alert for the drowse or the alert for the inattentiveness is executed based on the detection result of the drowse, the detection result of the inattentiveness, and the detection result of the vehicle speed; and
in the case where the vehicle speed is equal to or lower than the threshold value, the one or more processors execute the alert of the drowse when the drowse of the driver is detected, and do not execute the alert of the inattentiveness even when the inattentiveness of the driver is detected.
