Abstract: Methods and apparatus are provided for controlling an autonomous vehicle. The control device includes an interface that establishes a connection to an autonomous vehicle, a processor that processes inputs and generates control commands to control at least one function of the autonomous vehicle, and an input arrangement with at least one control element that is assigned to a function of the autonomous vehicle. The control device transitions a controller of the autonomous vehicle to operate in at least one of a first remote operation mode and a second remote operation mode in which the autonomous vehicle is controlled by the control device, when the control device is connected to the autonomous vehicle via the interface. At least one function of a scope of functions of the autonomous vehicle is restricted in the first remote operation mode and the second remote operation mode.

Abstract: Braking systems and methods for an autonomous vehicle are provided. Braking devices are associated with respective wheels of the autonomous vehicle. A hydraulic circuit is connected between a primary braking module (PBM) and the braking devices and connected between a secondary braking module (SBM) and the braking devices. One of a PBM electronic control unit and a SBM electronic control unit is configured to: in response to detecting a communications failure of the other braking module, apply a predetermined hydraulic pressure operation in the hydraulic circuit. The other of the PBM electronic control unit and the SBM electronic control unit is configured to identify, based on output from the at least one sensor, the predetermined hydraulic pressure operation being applied by the one of the PBM electronic control unit and the SBM electronic control unit, and select and execute a braking profile based thereon.

Abstract: Systems, methods and apparatuses are provided for detecting faults. The system includes a fault diagnostic computer in an autonomous vehicle configured to, via at least a first platform and a second platform, receive parameter data for processing simultaneously the parameter data in each platform wherein the first and second platforms are redundant configurations of each other wherein the parameter data includes a characteristic of a data; a check platform, coupled to the first and second platforms, for performing a method for checking the parameter data processed by both platforms using a collision test, the method includes: detecting, by applications of the collision test to one or more corresponding data found on each platform, collisions of the data within a tolerance prescribed by the collision test; and determining faults, in either the first platform, the second platform or both, based on results of comparisons of parameter data of the detected collisions.
