摘要:
A vehicle control multi-core system for controlling a device mounted on a vehicle (10) by using a plurality of cores (14 to 17), includes a computation process unit (2) that is executed on the plurality of cores and required for the control of the device, and a core failure determination unit (5) that compares a result of a computation process executed by the computation process unit at a specific timing on a specific core among the plurality of cores, with a result of a computation process executed by the computation process unit at a timing different from the specific timing on another core different from the specific core among the plurality of cores to determine that a failure occurs on the specific core.
摘要:
Disclosed herein is a battery state estimation system 110 which estimates a state of charge of a chargeable battery 400. The battery state estimation system 110 comprises: an SOCv computing unit 111 which calculates a state of charge of the battery 400 using a voltage applied across the battery 400; an SOCi computing unit 112 which integrates a current flowing through the battery 400 to calculate a state of charge of the battery 400; and an SOCw computing unit which performs weighted addition to the state of charge of the battery 400 calculated by the SOCv computing unit 111 and the state of charge of the battery 400 calculated by the SOCi computing unit 112, wherein when the temperature of the battery 400 is a predetermined temperature threshold value or less and the current flowing through the battery 400 is a predetermined current threshold value or less, the SOCw computing unit sets the specific gravity at the state of charge of the battery 400 calculated by the SOCi computing unit 112 larger than that in other cases upon the weighted addition.
