    Abstract: Systems and methods are provided for personalizing autonomous driving. The system can receive historical data on a driver of the vehicle's performance and population data indicating a population driving style. Speed data can be recorded as the driver of the vehicle drives the vehicle during a trial period. The historical data, population data, and speed data can be input into a machine learning model to determine a style for the driver. The system can receive one or more parameters from the machine learning model indicating the style. These parameters can be applied to the vehicle's automated driving system.

  • Publication number: 20250115153
    Abstract: A vehicle performs power transfer between the vehicle and electrical equipment while communicating therewith. A control device requests the electrical equipment to wait during the power transfer, sets the vehicle to the standby state when the standby request is accepted by the electrical equipment, and resumes the power transfer when the resumption condition is satisfied when the vehicle is in the standby state. The standby includes a first standby in which the vehicle stands by in a state in which the power transfer is stopped but the communication with the electrical equipment is maintained, and a second standby in which the vehicle stands by in a state in which both the power transfer and the communication therewith are stopped. The control device determines which of the first standby and the second standby is required for the electrical equipment by using the remaining capacity of an energy storage device.

  • Publication number: 20250115164
    Abstract: Direct-current power of a battery is converted to alternating-current power by an inverter to drive a motor generator. A control ECU executes temperature raising control when the battery is at a low temperature. During the temperature raising control, the control ECU superimposes a current ripple for raising the temperature of the battery on a d-axis current command value. A frequency of the current ripple (ripple frequency) varies randomly around a resonance frequency of a battery circuit including the battery. Additionally, a carrier frequency of the inverter varies randomly. As a result, a sound pressure level can be suppressed in regions of the resonance frequency and the carrier frequency during the temperature raising control.
