摘要： Provided is a vehicle control device capable of executing control processing by utilizing a power saving execution determination unit that determines a shift to or a release from a normal mode to a power saving mode on the basis of a preset power saving condition, and a power saving execution unit that executes power saving control of the CPU by determining a shift to the power saving mode and stops the power saving control of the CPU by determining a release of the power saving mode. Then, the power saving execution determination unit has a plurality of power saving conditions, determines to shift to the power saving mode in a case where all of the plurality of power saving conditions are satisfied, and determines to release the power saving mode in the case of being changed to a state in which some of the power saving conditions are not satisfied.

摘要： Provided are a vehicle control device and a computer program capable of simplifying design of state transition. An intermediate layer constituting an ECU divides a state of a lower-layer state machine for each function of a vehicle system in association with the state of the lower-layer state machine, and outputs the state to an upper-layer state machine, a state transition table of the upper-layer state machine includes, as a condition of state transition of the upper-layer state machine, a current state of a lower-layer state machine or a state to transition, and the upper-layer state machine receives the state of the lower-layer state machine input from the intermediate layer, refers to the state transition table, and outputs a signal for controlling the vehicle system.

摘要： An object of the present invention is to provide a technology that enables second control software to continue processing using a peripheral circuit even in a situation where an abnormality related to first control software occurs. An electronic control device includes a memory (3) that stores the first control software and the second control software, a CPU (1) that executes the first control software and the second control software, and a peripheral circuit (200) used by the first control software and the second control software. The memory further includes a first buffer (313a) and a second buffer (323a). The CPU interrupts at least one of the processing of storing first peripheral transmission information in the first buffer and the processing of transmitting the first peripheral transmission information to the peripheral in a specific situation in which the abnormality related to the first control software occurs.
