  • Multi-level vehicle integrity and quality control mechanism
    Patent number: 9457815
    Abstract: The processor-implemented control system for automotive vehicles assigns master control functionality separately to each controlled direction of motion. Within each master control, a multi-layered control architecture is implemented. At control level 0 multiple localized actuators associated with the controlled motion direction are monitored to ensure integrity but are otherwise allowed to operate on their own. At control level 1 the master control plays a supervisory role, coordinating behavior of the multiple actuators. At levels 2 and 3 the master control assesses trustworthiness of the driver and factors that trustworthiness into the control equation.
