Embodiment Construction

[0040] This description illustrates the principles of the disclosure according to the invention. It will thus be appreciated that those skilled in the art will be able to devise many different arrangements which, although not described in detail herein, are intended to reflect principles according to the disclosure of the invention and should likewise be described in protected within its scope.

[0041] figure 1 Cars are shown. Shown is Sedan (Pkw). However, any other vehicle is likewise conceivable as the vehicle. Examples of other vehicles are: buses, commercial vehicles, especially trucks (Lkw), agricultural machines, construction machines, motorcycles, rail vehicles and the like. The vehicle is designated by reference number 10 . The vehicle is equipped with 4 wheels as a sedan (Pkw). Current braking systems are often also equipped with drive antiskid systems ASR. For this purpose, the wheel speeds of all 4 wheels are detected, which also applies to the anti-lock fu...

Abstract

A device for control of a safety-relevant process is provided in the invention. For automated driving, safety precautions are necessary. The brake system is a redundant design including primary and secondary brake systems. Both brake systems safely decelerate the transportation vehicle and take over the function of the other brake system. The control of the safety-relevant process is based on theanalysis of the signals of at least one sensor (120); wherein for the brake process, it is a wheel rotation speed sensor. A hardware architecture and a test mode for the hardware architecture are provided. A communications bus (140) enables exchange of data between the primary and secondary control units. The at least one sensor of the hardware architecture connects to the primary control unit (110) and to the secondary control unit (130), wherein a respective sensor arrangement isolation circuit (116, 136) is associated with the primary control unit and the secondary control unit, which isolates the associated primary or secondary control unit from the at least one sensor (120).

Description

technical field [0001] Autonomous driving (also sometimes referred to as self-driving or automated driving or navigated driving) is understood as the advancement of vehicles, mobile robots, and driverless transportation systems that operate largely autonomously. There are several different levels of autonomous driving concepts. If, in some cases, only the driver who monitors the automated driving process is present in the vehicle, the automated driving is responsible for the defined classification. In Europe a number of different transport authorities (in Germany the federal agencies involved in transport) work together and define the following levels of automation. [0002] ·Level 0: "Driver only", the driver drives, steers, refuels, brakes, etc. by himself. [0003] • Level 1: Assistance systems for the determination of vehicle conditions (among them also the distance control system—Automatic Cruise Control (ACC)). [0004] · Level 2: Partial automation. Among them are a...
