A vehicle includes a door, an inside door handle, and a door opening warning system having an object sensor that detects an object outside the vehicle in a door collision risk zone, a touchless sensor that detects if a part of a user is positioned in an opening zone at the inside door handle and a touch sensor that detects if the user touches the inside door handle, and a control unit. The control unit triggers a first alarm if the object sensor detects an object in the risk zone and the touchless sensor detects a part of the user in the opening zone at the inside door handle, and triggers a second alarm if the object sensor detects an object in the risk zone and the touch sensor detects that the user is touching the inside door handle.

A method for determining a status of a vehicle battery includes determining an initial temperature and an initial state of charge of the battery, determining a current threshold value based on the initial temperature and the initial state of charge of the battery, starting the vehicle engine, charging the battery for a predetermined charging period t, measuring two charging currents, Iand I, to the battery at two predetermined points in time during the charging period t, determining an expected current value at a time t=t+tbased on the measured charging currents, comparing the expected current value with the current threshold value, and determining the battery is faulty if the expected current value is lower than the current threshold value.

A method for performing a diagnostic test of an alternator, a test arrangement and a vehicle are provided. The method may include running an engine, providing a signal representative of a pre-determined environmental condition to the alternator, providing an output voltage and output current to a battery based on the pre-determined environmental condition, and determining a battery voltage. The method may also include comparing the determined battery voltage with a pre-defined reference-voltage representative of the pre-determined environmental condition and outputting an approved test result if the difference between the determined battery voltage and the pre-defined reference voltage falls within a predetermined range.
