Abstract: Method and system for interfacing a plurality of providers and a plurality of recipients that are independently located with a unified vehicle service framework having a quality of service filter and a broker module. A first cloud unit has at least one of the plurality of providers and the plurality of recipients. A first vehicle and a second vehicle each respectively have another at least one of the plurality of providers and the plurality of recipients. A second cloud unit has yet another at least one of the plurality of providers and the plurality of recipients. The unified vehicle service framework is configured to receive a subscription request and determine whether it is granted based in part on a quality of service score assigned by the quality of service filter. When the subscription request is granted, respective services from plurality of providers are routed through the broker module.

Abstract: A system and method for object detection and classification includes receiving by a controller a first data of a scene, wherein the data reflects the scene at a first time, and performing a first classification of at least one object within the scene based on the data. The method includes determining a projected location of the at least one object corresponding to an estimated location at a second time. The method includes receiving a second data of the scene reflecting the scene at the second time. The method includes determining whether the projected location of the object corresponds to the location of the object as reflected by the second data. The method includes determining whether performing a second classification of the object is necessary based on the determination of whether the projected location corresponds to the location of the object reflected by the second data.

Abstract: A method for dynamically re-allocating controller functions based on minimizing utilization. A lookup table is generated based on functions and mode of operations. Each entry in the lookup table includes a number of executions required for a respective function in a respective mode of operation. Functions for execution to the controllers are assigned based on the number of executions for a function of an entry of a respective mode of operation. A utilization rate is determined for each controller in each mode of operation. Utilization rates of the various modes of operation are compared for each of the controllers. Matching utilization rates are identified between controllers of different modes of operations. A multi-mode re-allocation of function execution in the controller is coordinated by switching a set of pre-allocated functions between different controllers within a respective mode of operation to reduce the utilization rate of at least one controller.

Abstract: A modified dual-duplex fail-operational control system. A primary controller includes a first processing unit and a second processing unit for executing a function. A first comparative module comparing the function results from the first and second processing unit to determine an error the first controller. A second controller includes a first processing unit and second processing unit. The first processing unit executes the function. The second processing unit operating in a non-redundant state and not executing the function while in the non-redundant state. A second comparative module determines whether an error is present in the second controller. A matching function result identified by the first comparative module of the first controller is input to second comparative module of the second controller to determine whether an error is present in the second controller utilizing only the matching function result identified by the first comparative module and the function result determined by the first processing unit of the second controller.

Abstract: An integrated fail-silence and fail-operational control system includes a primary controller controlling features of devices while operating under non-fault operating conditions. A secondary controller includes a fail detector/decider module monitoring faults in the primary controller. The fail detector/decider module determines whether the fault in the primary controller is associated with a fail-silence requirement or a fail-operational requirement. If the fail detector/decider module determines the fault is a fail-silence requirement, then the fail detector/decider module actuates a shutdown command to the primary controller to shut down a feature affected by the fault where the feature becomes non-operational. If the fail detector/decider module determines that the feature associated with the fault is a fail-operational requirement, then the fail detector/decider module signals the primary controller to relinquish controls of the feature to the secondary controller. The secondary controller functions as a high assurance system for controlling the feature in a fail-operational mode.

Abstract translation: 集成的故障静默和故障操作控制系统包括主控制器，在非故障运行条件下运行时控制设备的特性。 次级控制器包括故障检测器/判定器模块，用于监视主控制器中的故障。 故障检测器/判定器模块确定主控制器中的故障是否与故障静默要求或故障操作要求相关联。 如果故障检测器/判定器模块确定故障是故障静默要求，则故障检测器/判定器模块致动到主控制器的关机命令，以关闭受特征变得不可操作的故障影响的特征。 如果故障检测器/判定器模块确定与故障相关联的特征是故障操作要求，则故障检测器/判定器模块发信号通知主控制器将特征的控制放弃到次级控制器。 辅助控制器作为在故障操作模式下控制特征的高保证系统。
