Abstract:
Embodiments are disclosed for methods and systems for selectively initializing elements of an operating system of a computing device. In some embodiments, a method of selectively loading hardware instances for a computing device includes receiving a notification identifying a driver for a hardware instance, initializing the driver identified in the notification, and for each hardware instance supported by the driver, determining if that hardware instance is associated with a first stage of initialization. The method may further include initializing the identified hardware instance and each other hardware instance supported by the driver that is associated with a first stage of initialization.
Abstract:
Es wird ein Verfahren zur Betriebsvalidierung einer Sensor-einheit (1) für ein Fahrzeug angegeben. Die Sensoreinheit (1) umfasst ein Sensorelement (3), eine Kommunikationsschnittstelle (4a), eine erste Steuervorrichtung (5) und eine zweite Steuervorrichtung (7). Die erste Steuervorrichtung (5) umfasst einen Speicher, in dem Programmcode zum Betreiben der Sensoreinheit (1) gespeichert ist. Die zweite Steuervorrichtung (7) umfasst einen Speicher, in dem eine Kopie des Programmcodes gespeichert ist. Bei dem Verfahren wird ein Messsignal durch das Sensorelement (3) erfasst. Jeweils ein Validierungssignal wird durch die Steuervorrichtungen (5, 7) ermittelt. Wenigstens eines der Validierungssignale wird der jeweils anderen Steuervorrichtung (5, 7) bereitgestellt und abhängig von den Validierungssignalen ein Validierungskennwert durch die jeweilige Steuervorrichtung (5, 7) ermittelt. Abhängig von dem Validierungskennwert und dem Messsignal wird ein Sensorsignal durch die erste Steuervorrichtung (5) und/oder durch die zweite Steuervorrichtung (7) ermittelt, das über die Kommunikationsschnittstelle (4a) der Sensoreinheit (1) bereitgestellt wird. Es wird ferner ein Tachographsystem (11) angegeben.
Abstract:
A vehicular control apparatus that functions more reliably is provided. A quasi-abnormality control circuit (65) brings one of a clock signal (A), an internal watchdog signal (B), and an answer signal (Ca) into a quasi-abnormal state when an ignition is switched on. A clock determining circuit (61), an internal watchdog signal determining circuit (62), and a Q&A watchdog circuit (63) output determination signals (DS)1 - DS3), respectively. One of the determination signals (DS1 - DS3) corresponds to a monitoring target signal brought into the quasi-abnormal state and indicates an abnormality. A reset signal determining circuit (64) receives the determination signals (DS1 - DS3), and generates a reset signal (R) in accordance with determination results in the determination signals (DS1 - DS3). A quasi-abnormality control circuit 65 switches the monitoring target signal to be brought into the quasi-abnormal state each time the ignition is switched on.
Abstract:
A diagnostic tool may include a user interface operating system comprising a computer processor that operates in a first operating environment. The diagnostic tool may also include a vehicle diagnostic operating system comprising a computer processor that operates in a second operating environment, wherein the second operating environment is different from the first operating environment.
Abstract:
An automotive internal combustion engine electronic control unit required to perform safety-related functions with a predetermined automotive safety integrity level; wherein the automotive internal combustion engine electronic control unit comprises a microcontroller and an integrated circuit distinct from, and communicating with the microcontroller; in which the microcontroller is designed to perform one or more safety-related functions with the same automotive safety integrity level as the one required to the automotive engine electronic control unit; in which the integrated circuit is designed to perform one or more safety-related functions with an automotive safety integrity level lower than the one of the microcontroller; in which the integrated circuit is further designed to perform, for each performed safety-related function, a corresponding diagnosis function designed to detect failures in the performance of the safety-related function; and in which the microcontroller is designed to perform, for each performed diagnosis function, a corresponding monitoring function designed to monitor the performance of the corresponding diagnosis function by the integrated circuit to detect failures that may compromise the diagnostic capability of the diagnosis function.
Abstract:
A method of servicing a hybrid system is disclosed wherein the hybrid system includes a detected fault. As a result of the detected fault the hybrid system has been disabled. The hybrid system includes a controller and a service detection interlock (SDI). The method steps include first powering up the controller and then assessing a special fault flag status. If a special fault flag is set, the next step is to check to see if the SDI is removed. If the SDI is removed then the special fault flag is cleared while the hybrid system remains disabled. The controller is then powered down with the key-off input and with the next key-on input, the hybrid system can be enabled.
Abstract:
A drive assist system includes: a movable body (20) in which drive assist is performed by an assist device (40, 50, 60) and which includes a movable body holding unit (23); an external holding unit (14) located outside the movable body (20); and a controller (22) configured to determine whether or not an operation position where the assist device (40, 50, 60) operates is related to the operation of the assist device (40, 50, 60), select the external holding unit (14) as a unit in which the operation result of the assist device (40, 50, 60) is to be held when it is determined that the operation position is not related to the operation of the assist device (40, 50, 60), and select the movable body holding unit (23) as the unit in which the operation result of the assist device (40, 50, 60) is to be held when it is determined that the operation position is related to the operation of the assist device (40, 50, 60).
Abstract:
A hybrid vehicle includes a hybrid module, a transmission and a torque converter. The lubrication system associated with the torque converter includes an oil sump within the torque converter housing which is intended to be managed as a "dry" sump oil lubrication system. There is an oil pump in communication with the sump in order to manage the sump oil level. By monitoring an operational parameter of the oil pump motor (pressure, torque, or current) oil aeration can be detected.
