  • Vehicular air conditioning device
    Patent number: 10744842
    Abstract: A vehicular air conditioning device includes a blower, a heating heat exchanger, an auxiliary heater, and a blower controller. The heating heat exchanger heats blown air by exchanging heat between the blown air and the cooling water of the in-vehicle device emitting heat during operation. The blower controller is configured to control the operation of the blower. The blower controller is configured to increase a blowing capacity of the blower with increase of a temperature of the cooling water. The blower controller, during operation of the auxiliary heater, increases the blowing capacity after a waiting time during which the increase of the blowing capacity is prohibited has elapsed since a start-up switch of a vehicle system is turned on.

  • VEHICLE CONTROL SYSTEM
    Publication number: 20200257290
    Abstract: When a subject vehicle reaches a position PNO in a middle of an interflow zone, it is judged whether conditions for automatic interflow are satisfied. When it is judged that the conditions for automatic interflow are not satisfied at the position PNO, a notification for urging manual interflow by a driver is started. Otherwise, the notification for manual interflow is not started. In a case where the notification for manual interflow was not started, when the subject vehicle reaches the position PGU between a distal end of an interflow zone and the position PNO, the notification for manual interflow is started.

  • Serial communication method and sensor controller
    Patent number: 10691254
    Abstract: A serial communication method between a device and a host, in which the device reports touch data including a coordinate of a detected active stylus to a host. The host issues a write command that includes data indicating a request of a descriptor, to the device. After the device performs a predetermined process for the write command, the device transmits an interrupt to the host. The host requests the device to transmit the touch data, triggered by the host detecting the interrupt. The device transmits the descriptor in response to a request for transmission of the touch data. The method can enable a sensor controller to notify the host of the descriptor even in a case where communication is performed between the sensor controller and a host processor in accordance with a standard that does not provide a command usable for the device to notify the host of the descriptor.
