When a driver is not in pedal erroneous operation inducing situation and a rate of change in an operation amount of an accelerator pedal is equal to or greater than a first erroneous operation determination threshold value, a driving assistance apparatus determines that operation of the accelerator pedal is erroneous operation. When the driver is in the pedal erroneous operation inducing situation and the rate of change in the operation amount of the accelerator pedal is equal to or greater than a second erroneous operation determination threshold value, the riving assistance apparatus determines that the operation of the accelerator pedal is the erroneous operation, and the second erroneous operation determination threshold value is smaller than the first erroneous operation determination threshold value.

A system operable to determine a future point of time, at which the alcohol concentration in blood of a user is less than a threshold value. The system includes an alcohol sensor operable to detect a current alcohol concentration in blood of the user, and a portable apparatus. The alcohol sensor and the portable apparatus each comprise a wireless communication apparatus. The wireless communication apparatus in the alcohol sensor is operable to wirelessly transmit the current alcohol concentration to the wireless communication apparatus in the portable apparatus.

A method automatically controls an actuator of a control system of an automotive device. The method includes determining a reference trajectory, determining a position of the device with respect to the reference trajectory, acquiring a parameter relating to a force exerted by a driver on a manual control device of the control system, and calculating a controlling setpoint of the actuator. The controlling setpoint is calculated as a function of the parameter and of the position of the device with respect to the reference trajectory.

Aspects of the invention are directed towards a system and method for safe decoupling of the external power supply from a vehicle. The technology described herein provides an indication or an alert to the user at an appropriate time and avoids the possible damage to the system. The system comprises an electrical port by which the refrigerator can be connected to an external AC mains supply via an electrical cable when the vehicle is in stationary state. The system further comprises a refrigerator main controller unit (RMU) for controlling the power delivered to the refrigerator in both stationary and driving states of the vehicle. There is a safety system installed for restricting the vehicle from being driven when the electrical port of the system is connected to the AC mains supply via the electrical cable and the refrigerator is powered by the AC mains supply.

Devices, methods and systems related to wearable patch having blood alcohol content detector. In some embodiments, a wearable patch can include a patch structure having one or more layers and configured to allow the patch to be worn by a user, and an analyzer component implemented on or at least partially within the patch structure and configured to measure alcohol content level in the user. The wearable patch can further include an interface component implemented on or at least partially within the patch structure and in communication with the analyzer component, with the interface component being configured to provide a notification based on the measured alcohol content. In some embodiments, such a wearable patch can be a part of a system such as a monitoring system or a compliance system.

The present disclosure is to provide a method of controlling limp home driving of a hybrid vehicle. When the hybrid vehicle enters into a limp home driving mode with a starter generator malfunctioning, a motor control unit performs constant voltage control on counter electromotive force of a motor, so that a constant voltage is supplied to high-voltage components as an input voltage, thereby ensuring that high-voltage components are protected and operable.

A plurality of driving force transmitting components of the same kind is categorized into a plurality of groups depending on a frequency range with the loudest operation sound. A component selection device stores mapping data that is data that defines mapping learned by machine learning. When the user-related information is input as an input variable, the mapping outputs a value corresponding to the input variable as an output variable. The vehicle component selection method causes the component selection method to execute: an input process inputting the user-related information into the mapping as the input variable; a selection process selecting the group corresponding to the output variable output by the mapping from the groups; and a determination process determining the driving force transmitting component categorized into the group selected in the selection process as a component to be installed in the vehicle for the user identified by the user-related information.
