Embodiment Construction

[0019] exist figure 1 The method according to the invention is described in , which at the same time shows a program for an existing microcomputer in a driver assistance device with the components necessary for explaining the invention.

[0020] In a first step 1, the sensor signals are pre-processed. The effect of this pre-processing is that the signals of different types of sensors are respectively available in an analyzable form as measurement data for subsequent analysis and calculation. In 2, these measured data are handed over to a program 3 for evaluating and calculating the measured data. These three steps or procedures 1 to 3 each require a processing time which adds up to a cycle time. In order to end the analysis and calculation in step 3, a branch is made in step 4 according to whether a trigger criterion is met. If the triggering criterion is met, a corresponding reaction is triggered in 5 , eg braking, and the measurement cycle is repeated in 1 .

Abstract

A method and a method for controlling a driver assistance device in which measured values ​​recorded by sensors are evaluated in order to trigger a reaction, wherein the measuring points in time are substantially repeated for The cyclic process for obtaining and evaluating the calculated measured values ​​is defined, wherein the measuring times are controlled in such a way that one of the measuring times follows as directly as possible a time at which a triggering measurement is expected value.

Description

technical field [0001] The invention relates to a method and a device for controlling a driver assistance device in which measured values ​​acquired by sensors are evaluated for triggering a reaction, wherein the measuring points in time are substantially repeated , Determination of the cyclic process for detection and analysis of calculated measured values. Background technique [0002] Driver assistance systems are devices in a motor vehicle that evaluate information (measured values) from the vehicle environment, for example by means of radar, lidar and / or video sensors. These measured values ​​collected by the sensors mainly originate from the environment outside the vehicle. Considered here are distances, directions and sizes relative to other vehicles or stationary objects as well as lane edges and lane markings. Other measured values ​​collected by the sensors relate to the vehicle, such as the current speed or the steering angle. Depending on the complexity of the...
