Electronic computing device having improved computing efficiency

There are provided a vehicle control device and a control method thereof capable of improving safety and reliability with a simple configuration. A vehicle control devicethat controls a vehicle includes an execution management unit Pthat manages execution of predetermined processing, an execution state recording unit Pthat records a history of execution states of the predetermined processing, and a setting information management unit Pthat manages setting information related to the execution of the predetermined processing. The setting information includes a jitter tolerance which is a tolerance of a jitter. The execution management unit Padjusts an execution timing of processing to be adjusted, which is included in the predetermined processing and in which the jitter is generated, based on the jitter tolerance of the processing to be adjusted.

Vehicle control device and control method thereof

In the present invention, when an abnormality occurs in a task, regardless of whether a critical section is being executed, timeout detection is realized by determining whether the critical section (CS) is necessary for the design in a preset task execution time and a certain period of time to distinguish between necessary interrupt disable and abnormal interrupt disable. A vehicle control device includes task execution means for causing a system to execute a task, and interrupt processing means for performing an interrupt process at the time of execution of the task. A maskable interrupt and a non-maskable interrupt that is commanded to execute after the maskable interrupt are included, the maskable interrupt is commanded to execute during an interrupt disable time, and then the non-maskable interrupt is executed.

Vehicle control device

An unpacking system that unpacks a box having flaps, including: an unsealing unit that cuts a proximity region where flaps facing each other in a closed state of flaps of the box come close together; a lid-opening unit that opens, at a predetermined angle exceeding 90 degrees, a predetermined flap of the flaps having been cut by the unsealing unit; and a flap cutting unit that cuts, along a side surface of the box, a base end side of the predetermined flap opened at the predetermined angle.

Unpacking system and unpacking method

In the present invention, computational efficiency degradation is suppressed when diagnosing a shared storage area in a vehicle control device in which a plurality of computing units are employed. This vehicle control device suppresses computational efficiency degradation by changing an access destination in a storage device while diagnosing a shared storage area that the storage device has.

The present invention provides a vehicle control apparatus in which a function stop caused by an access conflict when a high load is applied can be suppressed. The vehicle control apparatus according to the present invention determines the occurrence tendency of access conflicts by using a function expressed by the number of times of performing exclusive control on a shared storage area and by the number of the resultant access conflicts.

Vehicle control apparatus

Executing control software with an appropriate execution priority in accordance with a safety standard in a vehicle control device that executes a plurality of control software having different safety standards suppresses priority degree reversal. A vehicle control device is provided with an execution waiting job list retaining a list of jobs waiting for execution by a processor. A request for calling higher safety software from lower safety software is inserted at a position in the execution waiting job list in accordance with the execution priority of the lower safety software.

In the present invention, on the basis of the results of determining whether or not a constituent element of a vehicle control device is malfunctioning, the malfunction determination logic for determining whether or not the vehicle control device as a whole is malfunctioning is caused to be easily reusable. This vehicle control device determines the level of functional malfunction of the vehicle control device on the basis of what combination of hardware configuring the vehicle control device is malfunctioning, and executes a failsafe function that is in accordance with the level of functional malfunction (see FIG.).
