  • Patent number: 11014550
    Abstract: A system and method for controlling a hybrid power-split transmission of a vehicle involve obtaining measured rotational speeds of an engine and an electric motor of the transmission, wherein the transmission comprises at least two input shafts having a gear set therebetween and an output shaft, wherein one input shaft is coupled to the engine and another input shaft is connected to the electric motor, determining a main torque profile for the electric motor based on a set of operating conditions of the vehicle, calculating a speed difference between the measured rotational speeds of the engine and the electric motor, determining a disturbance torque profile for the electric motor based on the calculated speed difference, and performing closed-loop control of the electric motor based on a combination of the main and disturbance torque profiles to mitigate a disturbance at the output shaft of the transmission.

  • Patent number: 10994722
    Abstract: Systems and methods for monitoring electrified vehicle powertrain propulsive torque and taking remedial action when needed involve continuously monitoring an error between the actual and requested propulsive torques and comparing the error to various threshold values. Error exceeding a particular threshold could be indicative of a malfunction, and the vehicle could be afforded an opportunity to regain equilibrium by temporarily decreasing torque output. When the error continues to exceed the threshold or another threshold, however, further remedial action could be required, such as shutting down the vehicle.

  • Patent number: 10974769
    Abstract: A structural small overlap rigid barrier (SORB) joining bracket for a vehicle having an underbody hold-down assembly, a cowl side assembly, and a body mount assembly configured to connect a vehicle body to a vehicle frame includes a cowl side coupling first portion configured to couple to the cowl side assembly, and an underbody coupling second portion configured to couple to the underbody hold-down assembly and the body mount assembly. The SORB joining bracket couples and maintains structural integrity between the underbody hold-down assembly and the cowl side assembly, and couples with the body mount assembly to increase vehicle load capacity by providing a direct load path into the frame of the vehicle. A frame extension tube assembly creates additional strength and stiffness via stack-up with the SORB joining bracket.

  • Patent number: 10976754
    Abstract: A method of a method of controlling a volume of material dispensed by a constant pressure adhesive and sealant dispensing system controlled by a controller during shots includes automatically adjusting a proportional valve control setting for an orifice size of a controlled pressure regulator. An orifice size control pressure corresponding to the proportional valve control setting is applied to an orifice size control inlet of the controlled pressure regulator. A volume of the material dispensed during each shot is monitored and when the volume of material dispensed during each shot of a predetermined number of successive shots is outside a target range, the proportional valve control setting is automatically adjusted by the controller.
