  • Patent number: 11027746
    Abstract: A driver state determination unit of a drive mode switching control device regularly or irregularly determines whether a driver's state is a state of being able to perform a driving operation in a manual drive mode. The drive mode switching control device determines whether an operation performed by the driver is an emergency override operation or a non-emergency override operation. The drive mode switching control device outputs a switching signal for switching an automatic drive mode to the manual drive mode when a determination result by the driver state determination unit immediately before detection of the emergency override operation is that a driver's state is a state of being able to perform a driving operation in the manual drive mode.

  • Patent number: 10778770
    Abstract: In a network system, an own subsystem recognition unit is provided in each of subsystems, and holds a state and a function of the own subsystem. A shared information communication unit acquires states and functions of the subsystems. An objective acceptance unit accepts a setting of a target state. A shared storage unit stores knowledge regarding a combination structure of functions of the respective subsystems necessary for realizing the target state. A structure setting unit automatically sets a combination structure of functions of the respective subsystems, including determining whether the function of each of the subsystems is to be activated, based on the target state, states and functions of the subsystems, and the knowledge regarding a combination structure. A role determination unit determines functions to be executed by the respective subsystems based on the automatically set combination structure. A role notification unit notifies the subsystems of the determined respective functions.

  • Publication number: 20190243362
    Abstract: A drive mode switch controller outputs a signal for switching from an automatic drive mode to a manual drive mode. An obtaining unit obtains sensing data indicating light intensity measured by a light intensity sensor, and stores the sensing data into a storage. A determination unit determines, based on the sensing data, whether a surrounding environment in the direction in which a vehicle travels satisfies a predetermined condition appropriate for switching the drive mode in a period predetermined for the switching. A signal output unit outputs a signal for performing the switching when the surrounding environment in the direction in which the vehicle travels is determined to satisfy the predetermined condition.

    Abstract: An obtaining unit obtains sensing data indicating a state of a driver from a monitoring sensor for monitoring the state of the driver. A determination unit determines a degree of concentration of the driver on driving based on the sensing data. A notification controller controls, when the determination unit determines that the degree of concentration satisfies a first criterion, a notification unit to notify, before the drive mode is switched, the driver that the drive mode will be switched to the automatic drive mode, and controls, when the determination unit determines that the degree of concentration does not satisfy the first criterion, the notification unit not to notify, before the drive mode is switched, the driver that the drive mode will be switched.
