Abstract

An in-vehicle control apparatus performs a hazard avoidance process. The in-vehicle control apparatus includes an anomaly determination section, an alarm control section, and a hazard avoidance control section. The anomaly determination section determines whether a driver is under driving inability state during travel of the vehicle, based on information on monitoring of state of the driver. The alarm control section activates an alarm annunciator to issue an alarm outwardly from the vehicle when the driver is determined to be under driving inability state. After the alarm annunciator starts the alarm, the hazard avoidance control section fails to perform the hazard avoidance process when the alarm is stopped by a manipulation of the driver and performs the hazard avoidance process when a specified time elapses under state where the alarm is not stopped since the starting of the alarm.

Claims

1. An in-vehicle control apparatus that performs monitoring of a state of a driver in a vehicle and controls behavior of the vehicle based on the monitoring to perform a hazard avoidance process,

the in-vehicle control apparatus comprising:

an anomaly determination section that determines whether a driver is under driving inability state where the driver is unable to drive during travel of the vehicle, based on information on the monitoring of the state of the driver;

an alarm control section that activates, as an alarm annunciator, a hazard warning flashing lamp provided on an outside of the vehicle to issue an alarm outwardly from the vehicle immediately when the anomaly determination section determines that the driver is under driving inability state; and

a hazard avoidance control section that, after the alarm annunciator starts the alarm outwardly from the vehicle,

fails to perform the hazard avoidance process when the alarm is stopped by a manipulation of the driver, the manipulation being applied to a hazard switch that is provided inside of the vehicle to turn off the hazard warning flashing lamp and

performs the hazard avoidance process when a specified time elapses under state where the alarm is not stopped since the starting of the alarm.

2. The in-vehicle control apparatus according to claim 1,

wherein:

the alarm control section allows the alarm annunciator to issue a first alarm outwardly from the vehicle immediately when the anomaly determination section determines that the driver is under driving inability state; and

the alarm control section allows the alarm annunciator to issue a second alarm outwardly from the vehicle when a specified time elapses since starting of the first alarm while confirming no response from the driver,

the second alarm being issued in a mode more easily recognized around the vehicle than the first alarm.

3. The in-vehicle control apparatus according to claim 1,

wherein

the alarm control section includes:

a first control that allows the alarm annunciator to issue an alarm outwardly from the vehicle immediately when the anomaly determination section determines that the driver is under driving inability state;

a second control that allows the alarm annunciator to issue an alarm outwardly from the vehicle when confirming no response from the driver for a specified time after the anomaly determination section determines that the driver is under driving inability state; and

a selection section that selects either the first control or the second control to issue an alarm.

4. The in-vehicle control apparatus according to claim 3,

wherein:

the anomaly determination section includes a plurality of determinations to determine that the driver is under driving inability state according to different determination criteria based on a state and behavior of the driver; and

the selection section selects either the first control or the second control to issue an alarm, depending on which of the determinations determines that the driver is in driving inability state.

5. The in-vehicle control apparatus according to claim 4,

wherein:

the plurality of determinations include a determination that determines that the driver is under viewing inability state where the driver is unable to view toward a front of the vehicle; and

the selection section allows the first control to issue an alarm when the driver is determined to be under driving inability state by the determination determining that the driver is under viewing inability state, among the plurality of determinations.

6. The in-vehicle control apparatus according to claim 3,

wherein

the selection section selects either the first control or the second control to issue an alarm, based on a vehicle speed of the vehicle.

7. The in-vehicle control apparatus according to claim 1,

wherein:

when determining that the driver exhibits a symptom of an abnormal state based on information on the monitoring of the state of the driver, the anomaly determination section starts incrementing a counter value of an anomaly counter; and

when the counter value reaches a specified threshold value, the anomaly determination section determines that the driver is under driving inability state.

8. The in-vehicle control apparatus according to claim 1,

wherein:

the alarm control section activates, as an additional alarm annunciator in addition to the hazard warning flashing lamp, a hazard display mark provided inside of the vehicle to issue an additional alarm inside the vehicle immediately when the anomaly determination section determines that the driver is under driving inability state; and

when the manipulation of the driver is applied to the hazard switch, the alarm from the hazard warning flashing lamp and the additional alarm from the hazard display mark are stopped.
