An in-vehicle software updating method includes: acquiring, after starting a software update, a voltage measurement value of an in-vehicle power source; and acquiring a progress rate in the software update in a case in which the voltage measurement value is equal to or less than a second threshold. In a case in which the progress rate is less than a set value, the software update is interrupted. In a case in which the progress rate is equal to or greater than the set value, an operation mode of the zone control unit is switched to a power saving mode, and a second predicted voltage value of the in-vehicle power source at the update completion time is calculated. The software update is continued in a case in which the second predicted voltage value is greater than a first threshold.

A diagnostic system includes a fan control circuit coupled to an electric fan and a microcontroller, and a sense line coupled to the fan control circuit and the microcontroller. The fan control circuit outputs a fan command sense signal at a duty cycle through the sense line to the microcontroller. A tachometer generates a tachometer signal at a frequency indicative of the rotational speed of the electric fan. A fan tachometer circuit receives the tachometer signal and outputs the tachometer sense signal at a frequency to the microcontroller in response to the tachometer signal. The microcontroller sets a second diagnostic flag to an error value indicating that the sense line has impaired operation if the frequency of the tachometer sense signal is within a desired frequency range, and a first diagnostic flag is equal to a first error value.

A moving part control system for a vehicle configured to cause a movement of a mechanical part for loosening the mechanical part from a stuck state to a loose state. The moving part control system includes an electrically controlled actuator device configured to cause a movement of the mechanical part, a processing circuitry configured to be operatively connected to the electrically controlled actuator device and configured to determine an amplitude and/or a frequency of an oscillating movement of the electrically controlled actuator device to determine if the mechanical part is in a stuck state or a loose state.

Methods and systems for autonomous and semi-autonomous vehicle control, routing, and automatic feature adjustment are disclosed. Sensors associated with autonomous operation features may be utilized to search an area for missing persons, stolen vehicles, or similar persons or items of interest. Sensor data associated with the features may be automatically collected and analyzed to passively search for missing persons or vehicles without vehicle operator involvement. Search criteria may be determined by a remote server and communicated to a plurality of vehicles within a search area. In response to which, sensor data may be collected and analyzed by the vehicles. When sensor data generated by a vehicle matches the search criteria, the vehicle may communicate the information to the remote server.

A vehicle includes: an instrument panel that displays an alarm to a driver; and an ECU that controls the instrument panel based on a setting as to whether the driver is to perform maintenance of the vehicle or not. In a first setting in which the driver is to perform maintenance, the ECU controls the instrument panel to display an alarm when a failure occurs in an on-vehicle device. In a second setting in which the driver is not to perform maintenance, the ECU controls the instrument panel not to display an alarm about a failure less influencing traveling.

There is disclosed an electrical connection unit for a refrigeration system comprising: a container defining an interior for containing electrical circuitry, the container having an external port configured to couple with an external connector; a closure moveable relative to the container between a closed configuration in which access to the interior is prevented, and an open configuration in which access to the interior is permitted. The closure has a locking portion defining a connector opening for receiving the connector, configured so that movement of the closure to the open configuration is prevented by interlocking engagement of the connector and the closure. There is also disclosed an associated method of coupling or decoupling a connector and an electrical connection unit.

A system detects tampering of an electronic system of a vehicle operated by a driver. The system receives historical occurrences of at least one diagnostic trouble code (DTC) generated by the onboard vehicle computing system based on sensor data received from a vehicle sensor during a trip. The system identifies a length of the trip and a speed of the vehicle when each DTC was generated. The system identifies a distance the vehicle had traveled when each DTC was generated. The system determines a subsequent trip was started, whether a driver operating the vehicle on the subsequent trip is a same driver or a new driver, whether DTCs were generated during the trip, and whether DTCs were generated during the subsequent trip. The system determines a tamper rating for the driver that indicates a likelihood that the driver has tampered with the vehicle.

Aspects of the disclosure relate to determining and responding to an internal state of a self-driving vehicle. For instance, an image of an interior of the vehicle captured by a camera mounted in the vehicle is received. The image is processed in order to identify one or more visible markers at predetermined locations within the vehicle. The internal state of the vehicle is determined based on the identified one or more visible markers. A responsive action is identified action using the determined internal state, and the vehicle is controlled in order to perform the responsive action.

A method and a system detect damage caused to a parked vehicle and identify the originator of the damage.

Disclosed is a method of providing active services based on big data using a remote start device of a vehicle. The method includes the steps of: collecting information related to the vehicle and a driver; deriving a behavior prediction value for predicting driver's behavior based on the collected information; operating an active service determination unit when the derived behavior prediction value meets a preset condition; determining, by the active service determination unit, proposal of an active service to the driver based on the collected vehicle-related information; determining a type of the active service and a time of providing the active service; transmitting proposal of the determined active service to a driver terminal to be displayed; and starting execution of the determined active service according to a change in the state of the driver terminal.
