Abstract: An example computer system includes memory hardware configured to store a machine learning model and historical driving data vector inputs, and processor hardware configured to execute instructions including training the machine learning model with the historical driving data vector inputs to generate a reconstructed driving data output, wherein the reconstructed driving data output includes at least one reconstruction error score indicative of a likelihood that a driving data input corresponds to a desired driving behavior, obtaining a current driving data input, and supplying the current driving data input to the machine learning model to generate a reconstruction error score based on the current driving data input. The instructions may include determining a driving score according to the reconstruction error score, identifying at least one driver notification according to the determined driving score, and transmitting the identified at least one driver notification to a computing device or display.

Abstract: A vehicle input device includes a touch sensor provided in a grip portion of a steering wheel, a holding position determiner configured to determine whether a user is holding the grip portion and determine a holding position at which the user is holding the grip portion based on an input signal from the touch sensor, an operation area setting unit configured to set an operation area of the touch sensor at a position adjacent to a thumb and an index finger of a user's hand based on the holding position, and an operation detector configured to detect an operation by a finger of the user to the operation area of the touch sensor.

Abstract: A vehicle device receives image data transmitted from a compartment camera photographing a driver. The vehicle device analyzes the image data received from the compartment camera, and detects a heart rate of the driver. The vehicle device wirelessly communicates with one or more wearable devices possessed by one or more people who ride on a vehicle. The vehicle device identifies a wearable device possessed by the driver by comparing biometric information transmitted from the one or more wearable devices with the heart rate of the driver.
