    摘要: An autonomous speed control function for autonomously controlling a traveling speed of the vehicle and an autonomous steering control function for autonomously controlling steering of the vehicle include executing first autonomous control where, when an external situation of the vehicle is recognizable from a captured image by a camera on the vehicle, the vehicle is autonomously controlled using information recognized from the captured image; executing second autonomous control in which information indicating the external situation of the vehicle is acquired from stored map information provided in the vehicle and the vehicle is autonomously controlled using the acquired information; specifying an unrecognizable area in which the external situation of the vehicle is unrecognizable from the captured image; and when the unrecognizable area is present on a travel route of the vehicle, switching from the first autonomous control to the second autonomous control before the vehicle enters the unrecognizable area.

    摘要: A vehicle speed/headway control function and a lane-keeping function are provided as driving assist functions to assist in a driving operation by a driver. A mode-switching controller is provided for switching between the modes. In the lane-keeping assist mode, it is assessed whether or not a traveling condition has been met that an actual vehicle speed of the host vehicle exceeds a speed limit of a roadway on which the host vehicle is traveling during lane-keeping travel in which “hands-off mode,” which allows the driver to remove their hands from the steering wheel, has been selected. The mode is switched from “hands-off mode” to “hands-on mode,” which has as a condition that the driver has their hands on the steering wheel, upon assessing that the traveling condition that the actual vehicle speed exceeds the speed limit has been met.

    摘要: A machine vision system comprising receiving means configured to receive image data indicative of an object to be classified where there is provided processing means with an initial neural network, the processing means configured to determine a differential equation describing the initial neural network algorithm based on the neural network parameters, and to determine a solution to the differential equation in the form of a series expansion; and to convert the series expansion to a finite series expansion by limiting the number of terms in the series expansion to a finite number; and to determine the output classification in dependence on the finite series expansion.

    摘要: A steering switch is provided on a spoke of a steering wheel for steering a vehicle, and includes a main switch pressed to input an ON/OFF operation of a drive assistance system installed in the vehicle, and an approval switch pressed to input an approval of a lane change executed by the drive assistance system. The approval switch is arranged adjacent to the upper side of the main switch.

    摘要: A control method for a hybrid vehicle is provided. The hybrid vehicle includes an electric motor (13) that drives the vehicle to travel, a generator (12) that supplies power to the electric motor (13), and an engine (11) that drives the generator (12). The control method includes: when bringing the electric motor (13) into a regenerative state, operating the generator to drive the engine (11) in a state in which fuel supply to the engine (11) is cut, thereby executing, in accordance with required deceleration, the motoring control for consuming the output power of the electric motor (13); and when the required deceleration decreases and driving of the engine (11) by the generator (12) is requested upon execution of the motoring control, imposing a restriction on a change in the rotational speed of the engine.

    摘要: A current control method and a current control device is configured to control an on-board charger that supplies current to high-power components and a battery. When the on-board charger is controlled, the current control is executed to supply output current to the high-power components and the battery such that the output current is a sum of a drive current to be supplied to high-power components capable of computing current consumption based on their own operating states and the charging current to the battery.
