  • Patent number: 10866033
    Abstract: A heat storage system using a heat storage container includes a tubular body, a chemical heat storage material accommodated in the tubular body, and a flow channel that penetrates the tubular body in a longitudinal direction. The heat storage system includes a diffusion layer for transporting liquid from the flow channel to the chemical heat storage material. The liquid functions as a reaction medium of the chemical heat storage material. The liquid is transported to the flow channel and the diffusion layer. The liquid transported to the diffusion layer reacts with the chemical heat storage material, the chemical heat storage material generates heat, and the liquid is vaporized by the heat to become heat transport fluid.

  • Patent number: 10845194
    Abstract: The present invention addresses the problem of providing an inertial force detection device with which it is possible to diagnose sensor output without hindrance even when a vehicle is traveling. In order to solve this problem, there is provided an inertial force detection device for measuring inertial force according to a displacement amount of an oscillating body, wherein a diagnosis voltage that is synchronous with an output command signal inputted from the outside is applied. Furthermore, the period over which the diagnosis voltage is applied is shorter, by a prescribed period, than a cycle of the output command signal. Furthermore, at least one of the period over which the diagnosis voltage is applied, the diagnosis voltage, a diagnosis threshold value, and a filter characteristic is varied according to the cycle of the output command signal.

  • Publication number: 20200361487
    Abstract: 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.
