Sub-resolution measurement of fuel in fuel tank. In an embodiment, data, which comprise discrete fuel levels in a fuel tank and fuel injection rates for an internal combustion engine, are received. The fuel injection rates are integrated over a traversed distance to produce a fuel consumption series, and the discrete fuel levels are clustered over the traversed distance to produce a fuel level series. The fuel consumption and fuel level series are synchronized into a model that is used to generate sub-resolution measurements of fuel levels between the discrete fuel levels.

An anti-theft method for an electric vehicle is provided. The anti-theft method for an electric vehicle includes the following steps. An electronic anti-theft function is activated. Whether the electric vehicle is moving is determined. Whether the temperature of the motor is greater than a critical value is determined. When the temperature of the motor of the electric vehicle exceeds the critical value, the motor is reversed to generate a reverse resistance.

A system can include at least one server in communication with a vehicle theft-prevention apparatus that comprises a plurality of sensors and at least one computing device. The at least one server can be configured to receive an authentication request from a particular application executed on a mobile device comprising user credentials. The at least one server can authenticate the authentication request as a particular user account, where the particular user account is associated with the vehicle theft-prevention apparatus. The at least one server can receive instructions from the particular application that the mobile device has moved outside of a geofence associated with the vehicle theft-prevention apparatus. The at least one server can send a command to the vehicle theft-prevention apparatus to enter an armed mode.

A vehicle control device includes: a peripheral target recognition unit that, based on a detection signal of an object detection sensor, recognizes a target existing around a vehicle; a person determination unit that, when the target is recognized, executes a person determination process of capturing the target with a first camera having a first resolution, and determining whether the target is a person; and a user authentication unit that, when the target is determined to be the person, executes a first user authentication process of capturing a first target person determined to be the person by the person determination unit, with a second camera having a second resolution higher than the first resolution, and collating a face image of the first target person with a face image of a registered user of the vehicle to determine whether the first target person is the registered user.

A vehicle theft-prevention apparatus can include at least one computing device and a cylindrical body configured to be positioned within a cup holder of a vehicle, the cylindrical body having a cup holder element on a top side. The vehicle theft-prevention apparatus can further include a fish-eye camera sensor on an upper portion of the body, a passive infrared sensor positioned in the body, and a plurality of legs mechanically connected to a locking mechanism and configured to extend to provide an outward force on the cup holder to prevent removal of the vehicle theft-prevention apparatus. The at least one computing device can comprise a processor and a memory and can be configured to capture a plurality of images from the fish-eye camera sensor, read a plurality of measurements from the PIR sensor, and trigger an alarm based on the plurality of images and the plurality of measurements.

A vehicle monitoring apparatus includes: a first communicator that receives specifying information for specifying a target vehicle from a server; and an acquirer that acquires driving information from the target vehicle, the driving information being information regarding driving of the target vehicle specified by the specifying information received by the first communicator. The first communicator transmits the driving information acquired by the acquirer to the server. For example, the acquirer may acquire the driving information obtained from the target vehicle through communication.
