Methods, devices, and processor-readable media for hand-on-wheel gesture controls are described. A steering wheel is virtually segmented into a plurality of radial segments. Each segment is assigned a semantic meaning. Control commands related to control functions are mapped to different virtual segments of the steering wheel. When a user performs a gesture on the steering wheel, the system recognizes the gesture and selects a control function based on the location of the hand relative to the steering wheel. In various embodiments, on-wheel hand gestures, on-wheel hand location, and voice commands may be used in various combinations to enable a user to perform a wide selection of functions using a small number of unique commands.

Method and systems for authenticating a source of a signal in a system comprising a multiplicity of electrical units. One embodiment comprises: receiving by a receiver a signal comprising a command and a characteristic added to the command; retrieving a characteristic of the signal; associating the characteristic with an alleged transmitter of the signal; determining a transmitter of the signal; decoding the command from the signal; and subject to the transmitter being the same as the alleged transmitter, and that the transmitter of the signal is authorized to send the command to the receiver, performing the command.

A key management method serves as an electronic control unit (ECU) in an onboard network system having a plurality of ECUs that perform communication by frames via a network. The method includes storing, in a first-type ECU, a shared key to be mutually shared with second-type ECUs, and executing encryption processing regarding a framed transmitted or received via the network, based on the shared key. The method further includes executing, by the first-type ECU, inspection of a security state of the shared key stored by the second type ECUs in a case where a vehicle is in at least one of the following particular states, including immediately after the vehicle is not driving and is entering the accessory-on state, immediately after the vehicle is not driving and the vehicle is entering the accessory-off state, and immediately after the vehicle engine is started.

An information processing device that executes a program includes: a storage unit that includes a plurality of regions for storing a rewritable program; a calculation unit that executes a program stored in the storage unit; a start region specification unit that specifies, from the plurality of regions, a start region in which the calculation unit is executing a program; a rule update unit that specifies a rewrite target region in which a program can be rewritten based on information on the specified start region; and a reception selection unit that selectively receives a rewrite program stored in the rewrite target region.

Vehicle corner modules (VCMs) connectable to a VCM-connection interface of a reference-frame of a vehicle platform, for regulating motion of a vehicle. When a wheel is mounted on a wheel-hub assembly of the VCM, a vehicle-connection interface of the VCM is disposed within a cylindrical footprint of the wheel. At least one of the at least one subsystem of the VCM is accommodated between the wheel-hub assembly and the vehicle-connection interface. Vehicle platforms are connectable to the VCMs. The connection of the vehicle platform to the VCM may include connection of subsystems of the VCM to electronic or flow subsystems mounted on the vehicle platform by connection of two portions of a multi-interface connection-element.

Systems and methods are provided for controlling power modes of a vehicle and for providing passive entry to the vehicle. A sleep command can be sent from a central controller to multiple domain controllers to enter a sleep state. When the sleep command is received by a first domain controller, a sleep state is entered. When the sleep command is received by a second domain controller, a stealth state is entered. While in the stealth state, the second domain controller periodically wakes up from a sleep state to monitor a condition. In response to detecting a first condition, the second domain controller returns to the sleep state. In response to detecting a second condition, the second domain controller sends a notification of the second condition to the central controller.

A wake-up control method for a Body Control Module (BCM) includes: step S1 writing IDs and wake-up level information of all Micro Controller Unit (MCU) pins serving as an external wake-up source to a retention RAM; step S2, setting a wake-up detection timer, and triggering a system to enter a low power consumption mode; step S3, after a wake-up detection time set by the wake-up detection timer expires, enabling power supply to all MCU pins, setting the corresponding MCU pin as an input pin according to the pin ID information written in step S1, and acquiring level information of the input pin; and step S4, comparing the level information of the input pin with the wake-up level information written in step S1, if they are consistent, writing the ID of the input pin that is to serve as a wake-up source to the retention RAM and triggering the system to enter a normal operating mode, and if they are inconsistent, disabling the power supply to the MCU pin. A wake-up control device for a BCM is further provided. The wake-up control method and the wake-up control device for a BCM reduce selection requirements for MCU chips, and provide more flexible hardware pin allocation and design for a wake-up source.

Embodiments of the invention include dielectric waveguides and connectors for dielectric waveguides. In an embodiment a dielectric waveguide connector may include an outer ring and one or more posts extending from the outer ring towards the center of the outer ring. In some embodiments, a first dielectric waveguide secured within the dielectric ring by the one or more posts. In another embodiment, an enclosure surrounding electronic components may include an enclosure wall having an interior surface and an exterior surface and a dielectric waveguide embedded within the enclosure wall. In an embodiment, a first end of the dielectric waveguide is substantially coplanar with the interior surface of the enclosure wall and a second end of the dielectric waveguide is substantially coplanar with the exterior surface of the enclosure wall.

A method used in an on-board network system, having electronic controllers that exchange messages and a fraud detecting electronic controller. The method includes determining whether a message transmitted conforms to fraud detection rules, and querying an external device whether there is delivery data for updating the fraud detection rules. When there is the delivery data for updating the fraud detection rules, receiving from an external device the delivery data, including updated fraud detection rules and network type information indicating a network type that the updated fraud detection rules are to be applied. The method also includes determining whether a vehicle in which the on-board network system is installed is running, and whether the network type information indicates a drive network that is connected to an electronic controller related to travel of the vehicle. When the network type information does not indicate the drive network, updating the fraud detection rules.

A misuse detection method used in an electronic control unit in a vehicle network system including multiple electronic control units that communicate with one another through networks. The misuse detection method includes receiving a target data frame at one time point, and receiving a reference data frame at another time point different than the one time point. The misuse detection method further includes performing, as misuse detection for the target data frame based on a certain rule specifying a reception interval between the one time point at which the target data frame is received and the other time point at which the reference data frame is received, and determining the target data frame received is for misuse based on a length of the reception interval.
