  • Patent number: 11780458
    Abstract: A smart driver safety system for a vehicle is described. The system includes a drowsy driver detector, an attention diversion monitor, an automatic mirror adjustment subsystem, and a plurality of actuators. The drowsy driver detector determines a head position of the driver and detects an eye position of the driver's eyes. When the driver's eyes are closed, the drowsy driver detector determines a time duration of an eye closure and compares the time duration to a drowsiness threshold. When the eye closure exceeds the drowsiness threshold, the drowsy driver detector generates a drowsiness alert signal. The attention diversion monitor detects an attention diversion based on the eye position and the eye closure and generates an attention diversion alert signal. The automatic mirror adjustment subsystem adjusts a side mirror of the vehicle based on the eye position and the head position.

  • Patent number: 11117487
    Abstract: An electric vehicle charge controller and charging method for controlling a charging rate for a battery of an electric vehicle is presented. The battery receives charge via a node connected to a power distribution source. The charge controller receiving a nodal voltage measurement for voltage at the node, receiving a value of electric power at the node, and determining a change in the electric power value based on a previous electric power value. When the change in electric power is greater than a load change threshold, the charge controller determines an estimate of voltage-to-load sensitivity. The charge controller determines the charging rate of the electric vehicle based on the nodal voltage, the determined voltage-to-load sensitivity, and a state of charge of the at least one battery, and controls the charging rate for the at least one battery in accordance with the determined charging rate.
