Abstract
A driver assistance device for a vehicle having a plurality of safety functions, such as in particular an LDW function and an LKS function, in which system-related boundary values are provided for the safety functions such that when they are undershot the safety function is activated and when they are exceeded the safety function is deactivated. The boundary values are developed to be variable.

A driver assistance device for a vehicle, comprising:
- a plurality of safety arrangements, including at least one of:
- an LDW function (LDW=lane departure warning) arrangement, and
- an LKS function (LKS=lane keeping support) arrangement;
- wherein system-related boundary values are provided for the safety functions such that when they are undershot the safety function is activated and when they are exceeded the safety function is deactivated, and
- wherein the boundary values are variable.
A method for controlling a driver assistance arrangement, which includes at least one of an LDW safety function and n LKS safety function, the method comprising:
- detecting a performance characteristic of the vehicle associated with at least one of the safety functions of the driver assistance device;
