Abstract
A method for activating a safety actuator of a motor vehicle, including: ascertaining an endangerment model of the motor vehicle with the aid of an anticipatory sensor system and at least one characteristic value of a driving operation of the motor vehicle; ascertaining a controllability of the motor vehicle by a driver of the motor vehicle with the aid of the at least one characteristic value; and activating the safety actuator to an extent which is a function of the endangerment model and the controllability.
Claims15
A method for activating a safety actuator of a motor vehicle, comprising:
- ascertaining an endangerment model of the motor vehicle with the aid of an anticipatory sensor system and at least one characteristic value of a driving operation of the motor vehicle;
- ascertaining a controllability of the motor vehicle by a driver of the motor vehicle with the aid of the at least one characteristic value, wherein the controllability represents a degree to which the driver is able to control the motor vehicle;
- and
- activating the safety actuator to an extent which is a function of the endangerment model and the controllability, wherein:
- the activating is based on a value associated with an intervention point located in a quadrant of a four-quadrant state diagram in which a first coordinate of the intervention point represents the controllability and a second coordinate of the intervention point represents a degree of endangerment as determined by the endangerment model,
- a first quadrant of the state diagram represents high controllability and high endangerment,
- a second quadrant of the state diagram represents low controllability and high endangerment,
- a third quadrant of the state diagram represents low controllability and low endangerment, and
- a fourth quadrant of the state diagram represents high controllability and low endangerment.
A device having a software program for carrying out a method for activating a safety actuator of a motor vehicle, comprising:
- ascertaining an endangerment model of the motor vehicle with the aid of an anticipatory sensor system and at least one characteristic value of a driving operation of the motor vehicle;
- ascertaining a controllability of the motor vehicle by a driver of the motor vehicle with the aid of the at least one characteristic value, wherein the controllability represents a degree to which the driver is able to control the motor vehicle;
- and
- activating the safety actuator to an extent which is a function of the endangerment model and the controllability, wherein:
- the activating is based on a value associated with an intervention point located in a quadrant of a four-quadrant state diagram in which a first coordinate of the intervention point represents the controllability and a second coordinate of the intervention point represents a degree of endangerment as determined by the endangerment model,
- a first quadrant of the state diagram represents high controllability and high endangerment,
- a second quadrant of the state diagram represents low controllability and high endangerment,
- a third quadrant of the state diagram represents low controllability and low endangerment, and
- a fourth quadrant of the state diagram represents high controllability and low endangerment.
