摘要： An electronic control device includes: a logic circuit for reconfiguring a plurality of arithmetic circuits including a first circuit and a second circuit; a reconfiguration controller that reconfigures the arithmetic circuits and checks the reconfigured arithmetic circuits based on reconfiguration commands; and a process controller that transmits the reconfiguration commands to the reconfiguration controller and instructs the arithmetic unit to execute operations, in which when a first reconfiguration command is received, the reconfiguration controller reconfigures and checks the first circuit, when the check of the first circuit by the reconfiguration controller is completed, the process controller instructs the first circuit to execute an operation, the process controller transmits a second reconfiguration command to the reconfiguration controller and instructs the reconfiguration controller to start to reconfigure the second circuit until the execution of a predetermined process of the first circuit is completed after completion of the reconfiguration of the first circuit.

摘要： An electronic control device includes a rewritable configuration memory composed of a plurality of frames in which logic circuit information is stored, a reconfiguration control unit configured to rewrite the logic circuit information of the frames, a logic unit configured to form a logic circuit based on the logic circuit information stored in the frames, and a configuration memory diagnosis unit configured to read the logical circuit information stored in the frames of the configuration memory and to perform error detection which is detection of an error in the stored logic circuit information, in which when the frames are rewritten by the reconfiguration control unit, the configuration memory diagnosis unit performs the error detection of ones of the frames that are rewritten prior to ones of the frames that are not rewritten.

摘要： Even in a case where an operation abnormality occurs in the arithmetic processing unit of the control device, control is safely shifted to the degeneration control microcomputer, and a vehicle control device capable of improving safety is realized.
There are provided an outside world recognition microcomputer 10b, a control microcomputer 11b that outputs a control command to the actuator control device, and a degeneration control microcomputer 12b to which control is shifted in a case where an abnormality occurs in the control microcomputer 11b. The outside world recognition microcomputer 10b calculates a collision potential based on information from the outside world, and determines whether to reset the control microcomputer 11b when an abnormality occurs in the control microcomputer 11b or to shift control to the degeneration control microcomputer 12b.-
