LIMP HOME MODE FOR AN AUTONOMOUS VEHICLE USING A SECONDARY AUTONOMOUS SENSOR SYSTEM
An autonomous driving system for an autonomous vehicle includes a plurality of on-board autonomous sensors that sense data related to operation of the autonomous vehicle and a surrounding environment and an automated driving controller in electronic communication with the plurality of on-board autonomous sensors. The automated driving controller is instructed to receive an indication one or more of the plurality of on-board autonomous sensors are non-functional and a secondary autonomous sensor system including one or more replacement sensors are installed. The automated driving controller is instructed to verify the secondary autonomous sensor system based on a security check and perform a redundancy check between the one or more replacement sensors and the plurality of on-board autonomous sensors. In response to determining the one or more replacement sensors are valid based on the redundancy check, the automated driving controller operates the autonomous vehicle in a limp home mode.

Method of using a single controller (ECU) for a fault-tolerant/fail-operational self-driving system
In a self-driving autonomous vehicle, a controller architecture includes multiple processors within the same box. Each processor monitors the others and takes appropriate safe action when needed. Some processors may run dormant or low priority redundant functions that become active when another processor is detected to have failed. The processors are independently powered and independently execute redundant algorithms from sensor data processing to actuation commands using different hardware capabilities (GPUs, processing cores, different input signals, etc.). Intentional hardware and software diversity improves fault tolerance. The resulting fault-tolerant/fail-operational system meets ISO26262 ASIL-D specifications based on a single electronic controller unit platform that can be used for self-driving vehicles.
System for controlling a self-driving vehicle
A self-driving motor vehicle including numerous control units and numerous program codes for controlling the functions of the autonomous driving and other functions of the self-driving vehicle. Numerous program codes used for an autonomous driving mode are applied redundantly to at least two different control units. The self-driving motor vehicle may then be operated in an at least a partially autonomous driving mode. In this mode, the functions directly needed for satisfying a passenger's desire are determined, and weighted with regard to their importance in fulfilling the passenger's desires. At least one function of a lower order is then shut off, if the available resources in functioning control units and/or the power level in the self-driving motor vehicle are insufficient to execute program code for executing this function of the lower order.
Method for dynamic context-based distribution of software in a vehicle control system, and a control system
Technologies and techniques for dynamic, context-based distribution of program codes in a control system in a vehicle. The control system includes numerous control units. The allocation of the program codes to the corresponding control units in the control system takes place using a global placement chart. The global placement chart is calculated on a computer, which may be located outside the control system. The data from the global placement chart are sent to the control system. Other aspects include an at least partially autonomous motor vehicle that has a control system for executing dynamic, context-based distribution of program codes.
