  • Patent number: 11975714
    Abstract: Presented are embedded control systems with logic for computation and data sharing, methods for making/using such systems, and vehicles with distributed sensors and embedded processing hardware for provisioning automated driving functionality. A method for operating embedded controllers connected with distributed sensors includes receiving a first data stream from a first sensor via a first embedded controller, and storing the first data stream with a first timestamp and data lifespan via a shared data buffer in a memory device. A second data stream is received from a second sensor via a second embedded controller. A timing impact of the second data stream is calculated based on the corresponding timestamp and data lifespan. Upon determining that the timing impact does not violate a timing constraint, the first data stream is purged from memory and the second data stream is stored with a second timestamp and data lifespan in the memory device.

  • Patent number: 11975728
    Abstract: A vehicle system for recommending driving automation based on occupant behavior and emotion includes one or more input devices. The input devices generate an input signal associated with sensor data indicative of a current emotion and a current driving pattern of an occupant. The vehicle system further includes a computer having a processor and a non-transitory computer readable storage medium (CRM). The CRM stores multiple occupant behavior profiles, with each occupant behavior profile including a unique occupant identification and multiple historical driving patterns. Each driving pattern has an associated historical emotion for the unique occupant identification. The processor is programmed to determine a deviation of the current driving pattern from the historical driving patterns, compare the deviation to a threshold, and generate a notification signal. The notification device provides the notification to recommend that the occupant actuate the vehicle system.
