Method for operating an autonomous driving safety or driver assistance system of a motor vehicle
First Claim
1. A method for operating an autonomous driving safety system or driver assistance system of a motor vehicle, the method comprising:
- continuously recording data using the autonomous driving safety or driver assistance system, wherein the data include at least one of vehicle-related data and vehicle surroundings-related data,continuously repeatedly deciding, based on the recorded data, whether a driving safety or driver assistance system process is to be autonomously initiated or carried out, andcarrying out a checking process, during which sensor data and parameter settings that are necessary for the operation of the driving safety or driver assistance system are checked for the plausibility thereof,wherein the checking process is carried out immediately following a start of travel of the motor vehicle,wherein in a period of time between the start of travel of the motor vehicle and a start of operation of the driving safety or driver assistance system, an auxiliary process for an immediate and safe auxiliary mode of the driving safety or driver assistance system having reduced functional scope is used,wherein the driving safety or driver assistance system acts at least as an emergency brake system, andwherein during the auxiliary mode of the driving safety or driver assistance system, a limit value for a maximum effective brake force of a brake system of the motor vehicle that is activated by the emergency brake system is reduced relative to a normal mode of the driving safety or driver assistance system.

Abstract
A method includes continuously recording, by the autonomous driving safety or driver assistance system, at least one of vehicle-related data and vehicle surroundings-related data, continuously repeatedly deciding, based on the recorded data, whether a driving safety or driver assistance system process is to be autonomously initiated or carried out, and carrying out a checking process, during which sensor data and parameter settings that are necessary for the operation of the driving safety or driver assistance system are checked for the plausibility thereof. The checking process is carried out immediately following a start of travel of the motor vehicle. In a period of time between the start of travel of the motor vehicle and a start of operation of the driving safety or driver assistance system, an auxiliary process for an immediate and safe auxiliary mode of the driving safety or driver assistance system is used during a checking period.

6. A method for operating an autonomous driving safety system or driver assistance system of a motor vehicle, the method comprising:
-
continuously recording data using the autonomous driving safety or driver assistance system, wherein the data include at least one of vehicle-related data and vehicle surroundings-related data, continuously repeatedly deciding, based on the recorded data, whether a driving safety or driver assistance system process is to be autonomously initiated or carried out, and carrying out a checking process, during which sensor data and parameter settings that are necessary for the operation of the driving safety or driver assistance system are checked for the plausibility thereof, wherein the checking process is carried out immediately following a start of travel of the motor vehicle, wherein in a period of time between the start of travel of the motor vehicle and a start of operation of the driving safety or driver assistance system, an auxiliary process for an immediate and safe auxiliary mode of the driving safety or driver assistance system having reduced functional scope is used, wherein the driving safety or driver assistance system acts at least as an emergency brake system, and wherein at least one of drive-related data of the motor vehicle, route-related data, traffic-related data, environment-related data, and data for assessing the driving activities of the driver of the motor vehicle are continuously recorded, wherein at least one of a position, a speed, and an acceleration of at least one motor vehicle ahead and/or the position of at least one stationary obstacle are recorded continuously, wherein based on the recorded data a decision is made continuously and repeatedly regarding whether an emergency braking process preventing a collision of the motor vehicle with at least one vehicle ahead and/or a stationary obstacle ahead, or at least reducing the consequences of such a collision, is to be autonomously initiated or carried out, wherein the auxiliary process for the auxiliary mode of the driving safety or driver assistance system uses previously determined assumptions and/or immediately available data about the operating state of the motor vehicle, about the geometry of the current route, about a current range of driving speeds of the motor vehicle, about the current traffic situation, and about the current driving activities of the driver, wherein during the course of the auxiliary process, the sensor data and parameter settings that are necessary for the operation of the auxiliary process are checked for the plausibility thereof, and wherein during the course of the auxiliary process a start scenario with the initial sensor data and initial parameter settings and with non-reduced functional scope is generated from plausible sensor data and parameter settings for the start of the operation of the driving safety or driver assistance system. - View Dependent Claims (7)

8. A method for operating an autonomous driving safety system or driver assistance system of a motor vehicle, the method comprising:
-
continuously recording data using the autonomous driving safety or driver assistance system, wherein the data include at least one of vehicle-related data and vehicle surroundings-related data, continuously repeatedly deciding, based on the recorded data, whether a driving safety or driver assistance system process is to be autonomously initiated or carried out, and carrying out a checking process, during which sensor data and parameter settings that are necessary for the operation of the driving safety or driver assistance system are checked for the plausibility thereof, wherein the checking process is carried out immediately following a start of travel of the motor vehicle, wherein in a period of time between the start of travel of the motor vehicle and a start of operation of the driving safety or driver assistance system, an auxiliary process for an immediate and safe auxiliary mode of the driving safety or driver assistance system having reduced functional scope is used, wherein an at least approximately turn-free route is assumed as a first assumption for the auxiliary process for the auxiliary mode of the driving safety or driver assistance system. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
