Problems solved by technology

[0009] The disadvantage is that only access to measurement data for accident situations that actually occurred
Scenarios without accident data, data from driving conditions in which the vehicle did not lose control, or data from accidents or near misses that were successfully avoided are not used in the method

Embodiment Construction

[0024] A series of terms are used below to describe the method according to the invention, which terms have been explained at the beginning of this text.

[0025] Test scenario 4 can be understood as a certain frame condition / environment, such as a vehicle driving through a curve. Other test scenarios 4 may include, for example, driving uphill or downhill, or driving straight in a lane with obstacles or other traffic participants, and many other test scenarios 4 are also envisaged here.

[0026] All physical and dynamic indicators are called test parameters P. The test parameters P include, for example, the width of the lane, the radius of curvature at the turn, the values ​​of the lane characteristics such as the coefficient of adhesion and the coefficient of friction, the temperature of the lane, the air humidity, the wind and the direction of the wind, the speed of the vehicle passing the turn, the lateral acceleration of the vehicle, the (where possible on each wheel), th...

Abstract

The invention relates to a method for validating a driver assistance system (3) of a vehicle. Tests (T) defined by test parameters (P) are carried out for a specified test scenario (4). At least one first test parameter (P) is determined during a first test (T(n)), and in order to generate a second test (T(n+1)), the first test (T(n)) is modified in order to adjust the first test parameter (P) within a critical range (7) assigned the first test parameter.

Description

technical field [0001] The invention relates to a method for validating a driving assistance system for a vehicle, in which tests defined by test parameters are carried out for predefined test scenarios. Background technique [0002] Almost all types of vehicles today include driver assistance systems with the aim of greatly reducing accidents or at least serious injuries and fatalities. [0003] Current driver assistance systems are individually designed for specific driving situations, such as Anti-lock Braking System (ABS) to prevent possible wheel locking, Electronic Stability Program (ESP) to prevent possible vehicle skidding, Automatic Cruise Control (ACC) ) allows easier following on the highway, Brake Assist assists the driver in emergency braking, Lane Keeping Assist (LKAS) helps the driver e.g. other driver assistance systems. Since only one driver assistance system is rarely used in modern vehicles, in vehicles of the newer generation extended assistance systems...
