    Abstract: Apparatus, methods and logic for vehicles to determine vehicle to vehicle (V2V) safety message transmission rates for transmitting V2V safety messages based on how frequently the vehicles actually need to exchange safety messages, including factors such as vehicle velocities, distances among vehicles, and on how quickly the inter-vehicle distances are closing up. The determined V2V safety message transmission rates are selectively dynamically adjusted in accordance with detected significant changes in one or more of the inter-vehicle distances or inter-vehicle speeds. To avoid needless frequent changes to the transmission rate, statistical modeling techniques including hypothesis testing and sequential change detection are selectively used to more accurately detect significant changes in inter-vehicle distances or inter-vehicle speeds that warrant a change to the message transmission rate.

    Abstract translation: 根据车辆实际需要交换安全信息的频率，确定车辆与车辆（V2V）安全信息传输速度的装置，方法和逻辑（V2V），用于传输V2V安全信息，包括车辆速度，车辆距离和 车辆间距离关闭多快。 所确定的V2V安全消息传输速率根据车辆间距离或车间速度中的一个或多个中检测到的显着变化而被选择性地动态地调节。 为了避免不必要地频繁地改变传输速率，选择性地使用包括假设测试和顺序改变检测在内的统计建模技术来更准确地检测车辆间距离或车辆间车辆速度的显着变化，这样可以改变消息传输速率。

    Abstract: The trustworthiness of vehicle-to-vehicle (V2V) messages received from one or more associated vehicles in the vicinity of a subject vehicle is determined autonomously by a false signal detection system of the subject vehicle. Physical evidence relating to the associated vehicles is collected, and a statistical model is used to perform an analysis of the collected data. A V2V message is received by the system from a first one of the associated vehicles and a trustworthiness level of the message is determined in accordance with a correlation between the received V2V message and the result of the analyzed physical data relating to the first associated vehicle. The correlation may be a comparison of data contained in the received V2V message relative to a result of a stochastic analysis of the physical data. The received V2V message may be any V2V safety message including Emergency Electronic Brake Light (EEBL) messages.

    Abstract: In an example embodiment herein, there is provided methods and a system for cloud-assisted threat defense for connected vehicles. A vehicle suitably includes an on-board computer system for operating and/or controlling various systems on the vehicle. The on-board computer system suitably operates in connection with or includes an on-board threat defense module for detecting and protecting against malware attacks and other security threats to the vehicle. In an example embodiment, a cloud-based security component or security cloud assists with the detection and protection against security threats and malware attacks to the vehicle while minimizing the processing load and memory requirements for the on-board threat defense module.

    Abstract: Controlled startup of devices is based on dynamic statistical predictions. Timely startup of onboard associated vehicle devices is based on dynamic statistical predictions and driver proximity to the vehicle. An apparatus for timely startup includes an interface operatively coupled with a power consuming device and control logic coupled with the interface. The control logic is operable in a first mode to perform processing for determining a presence of a first condition of the vehicle, and to selectively activate the power consuming device of the vehicle, via the interface, responsive to determining the presence of the first condition. The control logic is operable in a second mode to suspend, via the interface, the processing for determining the presence of the first condition of the vehicle. The control logic selectively transitions between the first and second modes in accordance with a stochastic modeling of the presence of the first condition over time.
