  • Patent number: 12233738
    Abstract: Presented are closed-loop feedback control systems for preconditioning batteries, methods for making/using such systems, and electric-drive vehicles with battery preconditioning capabilities. A method for operating a battery system of a motor vehicle includes a system controller receiving a recharge signal to schedule a recharge event for a battery of the vehicle. The system controller responsively derives a target preconditioning temperature for optimizing the battery recharge event, and determines the battery state of voltage or charge for at the vehicle's current location. The system controller also predicts an SOV/SOC for the battery upon arrival of the motor vehicle at a selected charging station, and estimates a preconditioning time to thermally precondition the battery to the target preconditioning temperature.

  • Patent number: 12237791
    Abstract: A method, apparatus, and control system are described for operating a multiphase motor drive system including a rotary electric machine and an inverter. An AC choke filter is arranged proximal to output leads from the inverter. A reference temperature associated with the AC choke filter is determined along with an operating point of the electric machine. Operation of the inverter is controlled based upon a temperature of the AC choke filter, the reference temperature, and an operating point of the electric machine. This includes modifying a switching frequency and a PWM type in a manner that reduces the AC choke filter temperature by reducing the occurrence of switching events to protect the AC choke filter based on temperature feedback.

  • Publication number: 20250058764
    Abstract: A control system for a vehicle having a vehicle drive system and a plurality of torque sources connected to the vehicle drive system instructs a first torque source of the plurality of torque sources to provide an instantaneous torque to the vehicle drive system. The data processing hardware further receives a vehicle drive requested torque output and obtains a first available torque source output of the first torque source. The data processing hardware calculates a first torque error based on the requested torque output and the first available torque source output for the first torque source. The data processing hardware determines whether the first torque error exceeds a torque error threshold, and, when the first torque error exceeds the torque error threshold, activates a first supplemental torque source of the plurality of the torque sources to provide a first supplemental torque output to the vehicle drive system.

  • Patent number: 12223741
    Abstract: A visual perception system includes a scanning camera, color sensor with color filter array (CFA), and a classifier node. The camera captures full color pixel images of a target object, e.g., a traffic light, and processes the pixel images through a narrow band pass filter (BPF), such that the narrow BPF outputs monochromatic images of the target object. The color sensor and CFA receive the monochromatic images. The color sensor has at least three color channels each corresponding to different colors of spectral data in the monochromatic images. The classifier node uses a predetermined classification decision tree to classify constituent pixels of the monochromatic images into different color bins as a corresponding color of interest. The color of interest may be used to perform a control action, e.g., via an automated driver assist system (ADAS) control unit or an indicator device.
