  • Patent number: 12121962
    Abstract: A system and method of manufacturing an aluminum fuel cell cradle includes providing a negative cast mold having cavities to form the cradle and providing a feeding mechanism disposed about the mold and in fluid communication with the cavities thereof. The feeding mechanism includes a plurality of primary risers connected to and in fluid communication with cavities. The method further includes melting a first metallic material to define a molten metallic material, and moving the mold to a vertical casting orientation about a rotational axis, while feeding molten metallic material through the runner to the cavities, and cooling the molten metallic material to define a solidified metallic material. A second solidification time in the risers is greater than a first solidification time in the mold such that shrinkage of the solidified metallic material occurs in the risers away from the mold.

  • Patent number: 12122381
    Abstract: A full speed range adaptive cruise control system for a vehicle that stops at an intersection includes one or more controllers that execute instructions to receive localization data and situational data related to the vehicle. The one or more controllers determine, based on localization data and situational data, that the vehicle is approaching an intersection and will come to a stop at the intersection, where the vehicle is part of a queue including one or more surrounding vehicles. In response to determining the vehicle has come to a stop, the controller determines a position of the vehicle within the queue and an overall length of the queue. The controller calculates an adaptive launch time based on at least the position of the vehicle within the queue, the overall length of the queue, the situational data, and a timing delay associated with the queue.

  • Patent number: 12122415
    Abstract: Methods and apparatus disclosed within provide a solution to problems associated with the use of either high frequency or low frequency radar signals. Methods of the present disclosure may transmit high frequency radar signals, transmit low frequency radar signals, receive reflected radar signals, and process the received radar signals using parameters respectively suited for processing high frequency and low frequency radar signals. Evaluations may be performed that allow an apparatus to adapt for limitations associated with the processing of high frequency radar data, the processing of low frequency radar data, or both. Different correlation functions may be performed that allow the apparatus to identify objects and to identify object velocities using different sets of program code instructions. These different evaluations and correlations may result in the generation of a set of “point-cloud” information that may be used by other processes of a sensing apparatus.

  • Patent number: 12122248
    Abstract: Presented are control systems for operating dual-independent drive unit (DIDU) powertrains, methods for making/operating such systems, and electric-drive vehicles with fault management and mitigation for DIDU axles. A method of operating a motor vehicle with a DIDU axle includes monitoring first and second drive units (DU) that are independently operable to drive respective road wheels via respective axle shafts of the DIDU axle. A vehicle controller receives an indication of a fault condition in the first DU from a fault sensing module and responsively determines a fault type for the fault condition. The controller ascertains the vehicle's current speed and determines a respective torque limit for each of the DIDU drive units based on the fault type and current vehicle speed. Torque output of the first DU is concomitantly constrained to a first torque limit while torque output of the second DU is constrained to a second torque limit.
