  • Patent number: 10766496
    Abstract: A method for detecting and characterizing a driving behavior of a driver or an autopilot in a transportation vehicle which has at least one acceleration sensor used to record data points which indicate a lateral acceleration and a longitudinal acceleration of the transportation vehicle over a time interval, and a control unit used to generate an image space as a GG diagram from the data points of at least one sub-section of the time interval. The image space is transformed by the control unit by a transformation into a parameter space and coordinates of accumulation points in the parameter space are acquired by the control unit. From the coordinates of the accumulation points, by using a classification algorithm, the control unit determines a classification value and/or a classification profile relating to the driving behavior.

    Abstract: A driving control device of a vehicle includes a brake device and an ECU. The brake device is configured to apply a braking force to wheels. The ECU is configured to perform driving support control by calculating target deceleration of the vehicle and controlling the brake device such that deceleration of the vehicle reaches the target deceleration, to stop the driving support control when the driving support control is unable to be performed normally, and to determine whether or not a driver is in an abnormal state. The ECU is configured to decelerate the vehicle by controlling the deceleration of the vehicle so as to reach a predetermined value or more, when the driving support control is unable to be performed normally due to factors other than abnormality of the braking device in a situation where a determination that the driver is in an abnormal state is made.

  • Patent number: 10597009
    Abstract: A road surface condition estimation device extracts a detection signal of a vibration power generation element during a ground contact section to detect a road surface condition. A threshold used for determination of the ground contact section is variable according to a traveling speed of a vehicle. As a result, even if a pulse level of an output voltage of the vibration power generation element changes according to the traveling speed of the vehicle, the threshold corresponding to the change can be set. The ground contact section is determined with the use of the above thresholds, thereby being capable of performing the determination with high accuracy. Therefore, the road surface condition can be detected with high accuracy based on the ground contact section determined with high accuracy.
