  • Patent number: 11993292
    Abstract: A automatic driving control apparatus for a vehicle can selectively switch a driving mode between a manual driving mode in which a driver manually performs driving operation of the own vehicle and an automatic driving mode in which driving operation is performed automatically along a set target traveling route. The automatic driving control apparatus includes a driving skill evaluation unit and a driving mode switching unit. The driving skill evaluation unit is configured to monitor the driving operation by the driver during traveling in the manual driving mode and evaluate a driving skill of the driver. The driving mode switching unit is configured to control the driving mode so as to be switchable to the automatic driving mode on condition that at least an evaluation value of the driver by the driving skill evaluation unit exceeds a threshold set in advance.

  • Patent number: 11845436
    Abstract: A vehicle travel locus transmission system to be mounted on a vehicle includes a GNSS receiver, a vehicle-side transceiver, a locator processor, a wheel speed sensor, a gyro sensor, and an acceleration rate sensor. The locator processor generates, on predetermined cycles, a latest first linear coordinate as a linear function parameter that couples latest first positional coordinates and second positional coordinates on a previous cycle. The first and second positional coordinates are to be acquired on the basis of a positioning signal received by the GNSS receiver. On the condition that an angle formed by the first linear coordinate with an extension of a second linear coordinate generated on the previous cycle exceeds a predetermined threshold, the locator processor sends data regarding the first linear coordinate together with vehicle identification data, from the vehicle-side transceiver to an external device.
