Abstract
Among other features, a time series of values of an electrical parameter of an electrical system of a vehicle is accessed. An event or a state of the vehicle is determined based on the time series of values of the electrical parameter. The event or state is communicated to an occupant of the vehicle or to a third party.
Claims30
An apparatus comprising
- a sensor electrically coupled to terminals of a battery located in a vehicle and connected to an electrical system of the vehicle, the sensor being configured to sense voltages at the terminals of the battery,
- a wireless communication device,
- a processor, and
- a memory to store instructions executable by the processor to
- (a) access values of voltages at the terminals of the battery sensed by the sensor,
- (b) control a variable frequency at which the values of the voltages are accessed, and
- (c) cause the wireless communication device to communicate information about the values of voltages at the terminals of the battery to a mobile device in the vicinity of the vehicle for determination of a locked or unlocked state of a door or an open or closed state of a window of the vehicle based on the values of voltages and based on known events or states corresponding to historical series of values of voltages at terminals of batteries of one or more vehicles and for delivery of an alert of the state of the door or the state of the window through a user interface of the mobile device.

An apparatus comprising
- a connector coupled electrically to a battery located in and connected to an electrical system of a vehicle,
- circuitry connected to sense voltages appearing at the connector,
- a wireless communication device, and
- a processor in operable communication with the circuitry and the wireless communication device and configured to access values of voltages at the terminals of the batteries by the sensor, control a variable frequency at which the values of the voltages are accessed, and cause the wireless communication device to communicate information about the values of voltages at the terminals of the battery to a mobile device in the vicinity of the vehicle for determination of a locked or unlocked state of the door or an open or closed state of a window of the vehicle based on the values of voltages and based on the values of voltages and on known events or states corresponding to historical streams of values of the voltages and for delivery of an alert of the state of the door or the state of the window through a user interface of the mobile device.

A method comprising
- receiving wirelessly at a mobile device information about voltages at terminals of a battery located in and connected to an electrical system of a vehicle,
- determining a locked or unlocked state of a door or an open or closed state of a window of the vehicle based on the received information about the voltages and based on known events or states corresponding to historical streams of values of the voltages, and
- communicating the locked or unlocked state of the door or an open or closed state of a window as an alert through a user interface of the mobile device to an occupant of the vehicle.
