Embodiment Construction

[0091] The system according to the invention involves the automatic description and evaluation of the safety and driving quality of a driver assistance system A on the basis of objective subjective perceptions of one or more passengers, whereby the driver assistance system A can be optimized in at least one further step.

[0092] Methods used to objectify the subjective impressions of passengers include the analysis of measured vehicle parameters such as longitudinal dynamics (engine and transmission operating characteristics and ride characteristics), lateral dynamics (handling, steering, chassis), vertical dynamics (chassis Comfort) and objective evaluation of environmental parameters. From the measured values ​​originating from sensors and controllers, in particular using fuzzy logic, a plurality of driving situations are independently recognized, physically evaluated and, if necessary, preferably evaluated online from the subjective perception of a handling expert.

Abstract

The invention relates to a method for optimizing a driver assistance system A, which method comprises the steps of specifying at least one driver assistance system A to be optimized, determining at least one vehicle parameter function that characterizes an operating state of a vehicle and at least one environment parameter function that characterizes the environment of the vehicle, calculating at least one driving situation characteristic value function that characterizes a driving situation of the vehicle, at least on the basis of the at least one vehicle parameter function and / or the at least one environment parameter function, calculating at least one control intervention characteristic value function that characterizes the activity of driver assistance system A, and calculating a correction function that depends on the at least one driving situation characteristic value function and characterizes a subjective perception of the driving situation by at least one vehicle occupant, at least on the basis of the of the at least one control intervention characteristic value function and on the basis of the at least one vehicle parameter function and / or the at least one environment parameter function.

Description

technical field [0001] The invention relates to a method and a device for optimizing a driver assistance system. Background technique [0002] Not only in the field of passenger cars (PKW), but also in the field of commercial vehicles (NFZ), driver assistance systems (Advanced Driver Assistance Systems - ADAS) have a wide range of applications that continue to grow. Driver assistance systems make an important contribution to increased active driving safety and contribute to increased driving comfort. [0003] In addition to systems that contribute particularly to driving safety, such as ABS (Antilock Brake System) and ESP (Electronic Stability Program), several driving assistance systems are offered in the PKW (passenger car) and NFZ (commercial vehicle) sectors Systems such as: automatic lights, parking assist, automatic cruise, high beam assist, emergency brake assist, fixed distance cruise, lane keeping assist, etc. These driver assistance systems not only increase safe...
