1. 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, andan LKS function (LKS=lane keeping support) arrangement;
wherein system-related boundary values are provided for the safety arrangements such that when they are not exceeded the safety arrangement is activated and when they are exceeded the safety arrangement is deactivated, andwherein the boundary values are variable and these boundary values are a function of a velocity of the vehicle, andwherein the boundary value of a lateral acceleration is described by the function

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.

15. A computer-implemented method for controlling a driver assistance arrangement, which includes at least one of an LDW function arrangement and an LKS function arrangement, the method comprising:
-
detecting, by a processor, a performance characteristic of the vehicle associated with at least one of the safety arrangements of the driver assistance device; determining, by the processor, a system boundary associated with the detected performance characteristic; and activating, by the processor, the at least one safety arrangement when the system boundary is not exceeded, and deactivating the at least one safety arrangement when the system boundary is exceeded, Wherein the boundary values are variable and this boundary value is a function of the velocity of the vehicle, and wherein the boundary value of a lateral acceleration is described by the function - View Dependent Claims (16)
