  • Publication number: 20240174215
    Abstract: When the remaining charge amount of the battery decreases to a predetermined value or less, the engine torque reduction control unit reduces the torque of the engine such that the operating point of the engine falls within a predetermined engine torque stable region. Then, in a state in which the operating point of the engine is within the engine torque stable region, the torque of the electric motor is controlled by the charging control unit so that the actual charge amount by the electric motor becomes a preset target charge amount. This makes it possible to recover the battery from a state in which the charge amount is insufficient.

  • Publication number: 20240174214
    Abstract: When the remaining charge level of the battery decreases to a predetermined first determination value or less, the engine rotational speed increase control unit increases the target lower limit rotational speed of the engine or of the motor to the target lower limit rotational speed so that the operating point of the engine falls within a predetermined engine torque stable region. Then, in a state where the operating point of the engine is within the engine torque stable region, the charge control unit controls the negative torque of the electric motor so that the actual charge level by the electric motor becomes a preset target charge level. The battery can thus be recovered from an insufficient charge level.

  • Publication number: 20240174245
    Abstract: A vehicle driving assistance apparatus executes a first control to display a first image by a displaying device and a second control including an autonomous deceleration control to autonomously decelerate the vehicle in response to the traffic information. The first image is an image which displays traffic information on a place where a vehicle will move. The vehicle driving assistance apparatus renders the second control valid or invalid, starts to display the first image at a predetermined valid-state point of time in a situation where the second control is rendered valid, and starts to display the first image at a predetermined invalid-state point of time in a situation where the second control is rendered invalid. The predetermined invalid-state point of time is earlier than the predetermined valid-state point of time.

  • Publication number: 20240174254
    Abstract: A system for communication-aware federated learning includes a server and edge nodes. Each of the edge nodes trains a machine learning model using first local data obtained by sensors of corresponding edge node. Each of the edge nodes obtains network bandwidth for a channel between corresponding edge node and the server. One or more of the edge nodes determines a level of compression based on the bandwidth for the channel, compresses the trained machine leaning model based on the determined level of compression, and transmits the compressed trained machine learning model to the server. The server decompresses the compressed trained machine learning models and aggregates the decompressed trained machine learning models to obtain the aggregated machine learning model, and transmits the aggregated machine learning model to each of the edge nodes. Each of the edge nodes receives the aggregated machine learning model from the server.
