  • Publication number: 20210009037
    Abstract: When a relationship between a distance from a rear camera to a target subject, and a ratio of a size of the target subject displayed on a monitor with respect to a size of the target subject reflected in a half-mirror, is determined while fixing an angle of view of the rear camera to a predetermined value, the angle of view of the rear camera is set such that a size of the target subject at an infinite distance in the relationship becomes a size that is 0.33 times to 0.5 times a size of the target subject that is reflected in the half-mirror.

  • Patent number: 10487546
    Abstract: This door locking device for a vehicle includes: an electronic key and an in-vehicle device. The electronic key stores a first threshold defining an extension of a first region in which an electric field intensity of a response request signal is strong and a second threshold for defining an extension of a second region in which an electric field intensity is weaker than the first region around the first region. The electronic key outputs, based on the electric field intensity of the response request signal and the first and second thresholds, a response signal including position information indicating whether the electronic key is in the first region, or is outside the first region but in the second region, or is outside the second region. Based on the received response signal, the in-vehicle device switches the door to an unlocked state or a locked state.

  • Publication number: 20190267642
    Abstract: A plant control system is equipped with a plant, an actuator that controls a state of the plant based on a command value, and an arithmetic device that calculates the command value through the use of state information indicating the state of the plant and that outputs the command value to the actuator. The arithmetic device adopts, as the command value, a value of u obtained by deleting a time differential of y from equations: dy/dt=f(y, u, d, t) and K4×dy/dt=K3×yref?K1×y+K2×(time integral of (yref?y))+K5.

  • Publication number: 20190260049
    Abstract: The power controller starts imposing the current limit when a condition for the current limit is met the condition, the condition being that the fuel cell does not generate to fulfill the requested amount of power generation while the fuel cell generates power at an upper limit of the supply capability of the fuel gas supply unit, and the power controller removes the current limit at a first predetermined increase rate determined when the requested amount of power generation exceeds a predetermined threshold below a rated power generation amount of the fuel cell and at a second increase rate higher than the first increase rate when the requested amount of power generation is the threshold or less, after the condition for the limit is dissolved.

  • Patent number: 9714004
    Abstract: An electronic key registration system includes an electronic key and a communication master. The electronic key transmits a registration code. The communication master receives the registration code from the electronic key, obtains key information using the registration code, and registers the key information. The registration code is set in accordance with the communication master to which the electronic key is registered. The communication master includes a level determination unit, which determines a key registration security level when the electronic key is registered to the communication master, and a registration execution unit, which obtains the key information using the registration code based on the determined key registration security level and registers the key information to the communication master.
