Abstract:
A motor vehicle (MV) is controlled to drive autonomously in agreement with a nominal path in response to nominal control signals (NCS) from a bank of control units (110). Safety policies (P) are provided via a first data-interface unit (163). The safety policies (P) describe mission-related rules to be followed during operation of the motor vehicle (MV). The safety policies (P) are based on a safety case (SC) stipulating how the motor vehicle (MV) shall be controlled to meet a functional safety standard. A watch unit (160) receives sensor signals (SS) from the motor vehicle (MV), and based thereon repeatedly generates commands ({cmd}) to update the boundary conditions ({bc}) aiming at confining the nominal path within limits that are given by the sensor signals (SS) and the at least one safety policy (P). The bank of control units reads out the set of boundary conditions ({bc}) and controls the motor vehicle (MV) to move in such a manner that the nominal path satisfies the boundary conditions ({bc}), and is thus be considered to be safe.
Abstract:
A system for controlling functions in a motor vehicle comprising a central node (CN) and a set of actuators (A1,..., An). The actuators (A1,..., An) are communicatively connected with the central node (CN) via a bus connection (B). The central node (CN) is configured so as to transmit signals (S) on the bus connection (B), which signals contain: at least one identity datum (ID1,..., IDn) identifying one of the actuators (A1,..., An) and control data indicating a setting ( 1 X,..., nX) of the identified actuator (A1,..., An). The actuators (A1,..., An) are configured so as to receive, via the bus connection (b), the signals (S) and, on the basis thereof, to adjust a respective setting so that at least one ordered function (FCN1,..., FCNm) is performed. Specifically, each actuator (A1,..., An) is configured so as to perform a set function. Each actuator (A1,..., An) is further associated with a respective predefined identity datum (I D1,..., IDn) that uniquely identifies the actuator within the vehicle.
Abstract:
A system for control of functions in a motor vehicle comprises at least one peripheral unit (PU1, PU2,..., PU(n-1), Pun) and a main unit (MU) in communicative connection therewith. The at least one peripheral unit (PU1, PU2,..., PU(n-1), Pun) is provided with at least one operating device (C11,..., Cn2) configured to be manipulated by an operator with the object of ordering a desired function of the vehicle. At least one peripheral unit (PU1, PU2,..., PU(n-1), Pun) is configured to generate a respective signal (S) indicating a setting (p11,..., pn2) of the at least one operating device (C11,..., Cn2) and an identity (ID1, ID2, …, ID(n-1), IDn) for the at least one peripheral unit. The main unit (MU) is configured to receive the signal (S) from the at least one peripheral unit (PU1, PU2,..., PU(n-1), Pun) and to generate on the basis thereof at least one command (cmd1, cmd2,..., cmd(n-1), cmdn) directed at causing the desired function to be effected.
Abstract:
A motor vehicle (MV) is controlled to drive autonomously via a bank of control units (110) generating nominal control signals (NCS), which are adapted to cause the motor vehicle (MV) to move in agreement with a nominal path. A data storage (140) contains a set of boundary conditions ({bc}) that the nominal path shall satisfy in order to be considered safe. Inter alia based on sensor signals (SS) reflecting a current status of the motor vehicle (MV), a safety unit (120) receives a set of safety-related parameters (P, R, S j , H) describing condition(s) under which the motor vehicle (MV) is currently operated. In response thereto, the safety unit (120) repeatedly generates at least one command ({cmd}) that updates the boundary conditions ({bc}) aiming at confining the nominal path within limits given by a current state of the set of safety-related parameters (P, R, S j , H). The bank of control units (110) reads out the set of boundary conditions ({bc}) from the data storage (140) and controls the motor vehicle (MV) to move in such a manner that the nominal path satisfies the boundary conditions ({bc}).
