Method for testing the function of a driver assistance system and control unit and reference device for a driver assistance system
First Claim
1. A method for testing the function of a driver assistance system of a vehicle, wherein an environment of the vehicle is detected by means of a sensor system, the method comprising the steps of:
- a) stimulating the driver assistance system by means of an external stimulation;
b) processing the external stimulation in the driver assistance system so that a stimulation response is obtained;
c) transmitting the external stimulation and/or information relating to the external stimulation to an external reference device and determining a reference response for the stimulation in the external reference device in accordance with a desired state of the driver assistance system; and
d) comparing the stimulation response with the reference response.

Abstract
A method for testing the function of a driver assistance system of a vehicle, wherein an environment of the vehicle is detected by means of a sensor system, includes the following steps: stimulating the driver assistance system by means of an external stimulation; processing the stimulation in the driver assistance system so that a stimulation response is obtained; transmitting the stimulation and/or information relating to the stimulation to an external reference device and determining a reference response for the stimulation in the external reference device in accordance with a desired state of the driver assistance system; and comparing the stimulation response with the reference response. The invention enables the functionality of a driver assistance system of a vehicle to be tested in a simple and cost-effective manner.
