Claim 7:
8. An automobile system comprising:
a driver incapacitation determination system that outputs a driver incapacitation signal measured to determine whether a driver of an automobile is incapacitated;
an SOS switch disposed in a position accessible to an automobile occupant, the SOS switch configured to output a SOS switch signal in response to being actuated by the automobile occupant;
a parking brake switch that operates a parking brake of the automobile, the parking brake switch configured to output a parking brake signal that reflects an operation state of the parking brake switch;
a brake system configured to slow a movement of the automobile that is running; and
a braking controller that is electrically connected to the driver incapacitation determination system, the SOS switch, the parking brake switch, and the brake system,
wherein the braking controller includes circuitry configured to
determine whether the driver is incapacitated based on a state of the driver incapacitation signal,
control the brake system so that the automobile decelerates at a first deceleration under a first condition, the first condition being that the parking brake switch is turned on by the occupant regardless of a result of the determination as to whether the driver is incapacitated and regardless of a state of the SOS switch signal while the automobile runs,
control the brake system so that the automobile decelerates at a second deceleration that is smaller than the first deceleration under a second condition, the second condition being that the parking brake signal indicates the parking brake switch is not turned on and the driver incapacitation signal indicates the driver of the automobile is incapacitated regardless of the state of the SOS switch as indicated by the SOS switch signal while the automobile runs, and
control the brake system so that the automobile decelerates at a third deceleration that is smaller than the first deceleration under a third condition, the third condition being that the SOS switch signal indicates the SOS switch is turned on, the parking brake signal indicates the parking brake switch is changed from on to off, and the driver incapacitation signal indicates the driver of the automobile is not incapacitated while the automobile runs.
