摘要:
A security architecture, a battery, and a motor vehicle that has a corresponding battery are configured to be used to combine battery packs of a lower security integrity level into a battery system that has a higher security integrity level. The security architecture is for at least two batteries and each battery includes at least one electrochemical cell. The at least two batteries are each combined with at least one data processing unit to form a respective module. The security architecture is configured such that input signals of at least one second module are processed by the at least one data processing unit of at least one first module.
摘要:
A method for initiating an operation under emergency conditions of a motor vehicle, the method including detecting a malfunction of a component of the motor vehicle; checking whether an operation under emergency conditions is possible; reporting the malfunction to the driver; initiating the operation under emergency conditions under predefined conditions, the operation under emergency conditions being initiated following an active confirmation by the driver.
摘要:
A method for monitoring at least two microcontrollers using a watchdog is described. The watchdog is associated with a first microcontroller and monitors the communication of a message from the first microcontroller within a time interval of a predefined duration. The message communicated to the watchdog by the first microcontroller contains a contribution which is formed on account of communication between the first microcontroller and a second microcontroller connected to the latter and on the basis of which the watchdog checks the proper method of operation of the second microcontroller. The disclosure also describes a circuit arrangement and a battery with a battery management unit which are configured to carry out the method according to the disclosure.
摘要:
A method for checking functions, to be checked, of a control system, the control system having components to be checked, in particular redundant components, and an evaluation unit which evaluates the operability of the components on the basis of status reports of the components, the method including a component-side check of the functions, to be checked, of the components to be checked, and a system-wide check of at least one, but not all, of the functions checked on the component side.
摘要:
A method for controlling an electrical machine of a hybrid drive includes: ascertaining at least one operating parameter value of the electrical machine; identifying an error, if the at least one operating parameter value does not correspond to the standard state of an operating parameter; and at least partially restricting the operation of the electrical machine as a propulsion unit if an identified error exists. The electrical machine is operated at least temporarily as a starter when an identified error exists, independently of the operation of the electrical machine as a propulsion unit.

摘要:
A method for operating a shutoff device for a device, in particular an internal combustion engine and/or an electric machine, in which an operating element for initiating a shutoff operation is provided, and in which a transmission path is provided via which a shutoff signal is transmitted from the operating element to the device in order to deactivate the device. The shutoff device is checked for proper functioning at least in part automatically, by automatically transmitting a shutoff signal, in particular from the operating element via the transmission path to the device.
摘要:
In a method for actuating at least one actuator, two control units and a selection logic are provided, and each of the control units is designed to influence the actuator. Each of the control units performs a self-diagnosis, and each of the control units generates at least one activating signal as a function of the self-diagnosis. The activating signal indicates which of the control units is to be activated. The selection logic activates one of the two control units for influencing the actuator as a function of the activating signals.

摘要:
In a method for operating an at least three-phase electric machine used as a drive assembly in a motor vehicle, which is actuated via an inverter, the inverter including switching elements in the form of half bridges which are in each case electrically connected to a respective phase of the electric machine, when a first switching element of a first half bridge connected to a first phase is permanently closed/opened on account of failure, a second switching element of the first half bridge is permanently opened/closed and, in a first angular range of an electrical rotation, which is uninfluenced by the first phase, all switching elements of the additional half bridges are actuated in the usual manner.
