Abstract
System for controlling a motor vehicle (MV) for autonomous driving, wherein the system comprises: a bank of control units (110) comprising a number of vehicle control units (ACU1, ..., ACUn) configured to generate target control signals (NCS) configured to cause the motor vehicle (MV) to move autonomously in accordance with a target path; and a monitoring unit (160) configured to receive sensor signals (SS) from the motor vehicle (MV) describing a current state of the motor vehicle (MV) and to generate commands ({cmd}) based on the control signals (SS) that influence how the bank of control units (110) generates the target control signals (NCS), characterized by the fact that the system further comprises: a data storage (140) comprising a set of boundary conditions ({bc}) that the target path must satisfy to be considered safe; and a first data interface unit (163) configured to provide at least one safety policy (P) describing an associated task-related rule to be followed during the operation of the motor vehicle (MV), wherein the first data interface unit (163) is configured to provide at least one safety policy (P) based on a safety event (SC) that prescribes how the motor vehicle (MV) should be controlled in order to meet a functional safety standard, wherein the monitoring unit (160) is configured to repeatedly generate the commands ({cmd}) to update the boundary conditions ({bc}), aiming to keep the target path within limits specified by the sensor signals (SS) and at least one safety policy (P), and wherein the bank of control units (110) is configured to: to read the set of boundary conditions ({bc}) from the data storage (140), and to control the motor vehicle (MV) to move in such a way that the desired path satisfies the boundary conditions ({bc}).
