摘要： An electronic control device includes: a partially reconfigurable logic circuit in which a calculation unit which is reconfigured and executes calculation and a storage unit which stores calculation target date to be calculated by the calculation unit is configured; and a processing control unit which transmits circuit data for reconfiguring the calculation unit and the calculation target date to the logic circuit. When the processing control unit obtains next calculation target date which is the calculation target date relating to a next calculation unit which is the calculation unit after completion of reconfiguration, transmission of the next calculation target date to the storage unit is started regardless of whether the reconfiguration of the next calculation unit is completed, and upon completion of the reconfiguration, the next calculation unit performs calculation using the next calculation target date.

摘要： A vehicle control device capable of improving safety, even when abnormality in the operation of an arithmetic processing unit occurs. A second microcomputer receives trajectory information transmitted from a first microcomputer via a communication line and calculates control commands to actuators to synchronize the arithmetic processing unit allowing the first and second microcomputers to be synchronized. The second microcomputer performs a calculation and compares the result with the calculation result of the first microcomputer so that the second microcomputer can accurately determine whether or not the first microcomputer is abnormal. When the abnormality occurs in the first microcomputer based on the determination, the actuators are controlled by switching to the control commands calculated by the second microcomputer which is synchronized with the arithmetic processing unit. Thus, the device performs seamless self-driving control without the occurrence of abrupt control gaps.
