Claim:
1. A driver assist arrangement configured to assist a driver of a vehicle hosting the arrangement in potentially hazardous driving situations, the arrangement comprising: a first yaw rate controller configured to control a yaw rate of the hosting vehicle by comparing an expected yaw rate with an actual yaw rate and in response thereto selectively apply brakes of respective wheels of the host vehicle; a hazard evaluation unit configured to detect an obstacle in a driving environment of the host vehicle and to evaluate a risk of an accident between the host vehicle and the detected obstacle; a driver intention evaluation unit configured to detect occurrence of an avoidance maneuver initiated by the driver; and a second yaw rate controller configured to intervene in the control of the first yaw rate controller if the evaluated risk of an accident is above a threshold value and occurrence of an avoidance maneuver initiated by the driver is detected, wherein the second yaw rate controller is configured to intervene in the control of the first yaw rate controller to allow a higher level of over-steer of the host vehicle than normally allowed by the first yaw rate controller.
