  • Publication number: 20210010909
    Abstract: According to one embodiment, a learning apparatus includes a memory and a hardware processor connected to the memory which learns a transformation function to extract a feature value of an input signal. The hardware processor updates the transformation function based on a signal indicative of a first condition and a signal indicative of a second condition which is different from the first condition, using a first loss function on the signal indicative of the first condition and a second loss function on the signal indicative of the second condition. The second loss function is designed such that the second condition becomes distant from the first condition.

  • Patent number: 10766488
    Abstract: A driving control device has a target-following driving control part performing a target-following driving control of a preceding vehicle in front of a vehicle, and a target acceleration setting part setting a target acceleration/deceleration of the vehicle to maintain a inter-vehicle distance between the vehicle and the preceding vehicle within a target inter-vehicle distance during the target-following driving control. The target acceleration setting part increases the target deceleration of the vehicle according to increasing of a difference between the inter-vehicle distance and the target inter-vehicle distance. A deceleration correction part increases the target deceleration when a period during which the preceding vehicle has been continuously recognized is more than a predetermined period and the inter-vehicle distance is less than a predetermined distance.
