  • Patent number: 10760479
    Abstract: A control system and method for an engine including a turbocharger without a surge valve involve utilizing one or more pressure sensors configured to measure air pressure in an intake system of the engine, the intake system comprising a compressor of the turbocharger and a throttle valve downstream from the compressor, and a controller configured to control the engine to avoid surge at the compressor and eliminate a need for the surge valve by determining a desired position for the throttle valve based on a driver requested engine torque, determining a minimum mass flow through the compressor that avoids surge based on the measured air pressure in the intake system and a predetermined compressor map, and commanding the throttle valve to a target position to maintain at least the minimum compressor mass flow, wherein the target position is greater than the desired position, thereby avoiding surge at the compressor.

  • Patent number: 10759409
    Abstract: A control system and method for a hybrid vehicle involve controlling a hybrid powertrain comprising an engine and a transmission having one or more electric motors and not comprising a decoupling mechanism therebetween, detecting an operating condition where the transmission is in neutral and the vehicle is moving at a speed less than a low speed threshold, and in response to detecting the operating condition: determining a desired propulsive torque of the powertrain, determining an actual propulsive torque at the driveline, calculating a torque difference between the actual and desired propulsive torques over a period, comparing the calculated torque difference to a first movement threshold, and when the calculated torque difference exceeds the first movement threshold, applying an electric parking brake (EPB) of the vehicle.

  • Patent number: 10762718
    Abstract: A system and method is disclosed for determining an optimal direction and a minimum directional negative distance between two objects. The system and method uses an iterative process involving rotating a vector about two or more axes to obtain a group of new vectors, determining which one of the new group of vectors has the smallest directional negative distance, comparing the vector having the smallest directional negative distance to a preset value, and repeating the above operations as needed until a vector is obtained which does not exceed the preset value, and which is then identified as the optimum directional vector having a minimal directional negative value.

  • Patent number: 10753459
    Abstract: A vehicle transmission braking mode comprises determining a set of available clutches of the plurality of clutches that are not being utilized for engagement of a particular forward gear of the plurality of forward gears, determining at least one of a modeled temperature, a measured temperature, and a modeled energy of each clutch of the set of available clutches to obtain a set of at least one of clutch temperatures and energies, and based on at least the set of available clutches and the set of at least one of clutch temperatures and energies, selectively operate the transmission in the transmission braking mode by at least partially applying at least one clutch of the set of available clutches to mitigate or prevent powerflow through the transmission and thereby decrease or maintain a speed of the vehicle and/or reduce acceleration of the vehicle.

  • Patent number: 10753461
    Abstract: Control systems and methods for a vehicle automatic transmission utilize a driver interface configured to receive input from a driver of the vehicle relating to a custom shift mode of the automatic transmission and a controller configured to monitor a driving history of the vehicle and, based on the driving history, determine a reduced shift sequence for the transmission to utilize during the custom shift mode, the reduced shift sequence specifying a subset of available forward gears of the transmission to utilize during the custom shift mode, the subset of gears being less than a total number of available forward gears of the transmission, such that one or more available forward gears are skipped in the reduced shift sequence, initiate the custom shift mode for the transmission, and during the custom shift mode, control shifting of the transmission according to the reduced shift sequence.

  • Patent number: 10744891
    Abstract: A system comprises a high voltage (HV) battery system connected to an HV bus, a motor generator unit (MGU) connected to the HV bus, a main contactor disposed on the HV bus between the MGU and the HV battery system such that, when the main contactor is closed, the HV battery system stabilizes a voltage of the HV bus, a low voltage (LV) battery system connected to an LV bus and configured to stabilize a voltage of the LV bus when the main contactor is open or malfunctioning, a direct current to direct current (DC-DC) converter connected to the HV bus and the LV bus, and a controller configured to (i) when the main contactor is closed, control the DC-DC converter to stabilize the LV bus voltage, and (ii) when the main contactor is open or malfunctioning, control the DC-DC converter to stabilize the HV bus voltage.

  • Patent number: 10730383
    Abstract: A system and method for controlling an active grille shutter system for a vehicle upon startup of an associated engine includes determining if flaps of the AGS system are in a closed position upon cold-startup of the vehicle; moving the flaps to the closed position if it is determined that the flaps are not in the closed position upon cold-startup of the vehicle; and maintaining the flaps in the closed position until an engine coolant temperature (ECT) reaches a predetermined temperature that initially overshoots a predetermined continuous ECT target associated with steady-state operation of the engine. The initial overshoot of the ECT during cold-startup is configured to rapidly raise an engine oil temperature (EOT) to a predetermined continuous EOT target thereby reducing viscosity of the engine oil during cold-startup operation and increasing fuel efficiency of the vehicle.

  • Patent number: 10731393
    Abstract: A dual platform bumper system for a vehicle includes a bumper configured to couple to one of the door or another vehicle component, the bumper having first and second points of contact, and a platform configured to couple to the other of the door and the other vehicle component. The platform includes an upper contact platform and a lower contact platform. The upper contact platform is configured to contact the first point of contact when the door is moved to a closed position, and the lower contact platform is configured to contact the second point of contact when the door is moved to the closed position to facilitate preventing over-travel relative movement of the at least one door.

  • Patent number: 10723317
    Abstract: A passive entry system for a vehicle includes a portable fob and a communication and control unit disposed on the vehicle, the communication and control unit configured to control a function of the vehicle. The portable fob and the communication and control unit are configured to communicate ultra-wideband (UWB) signals therebetween. When the function of the vehicle is triggered, the communication and control unit initiates a double-sided UWB ranging session with the portable fob where (i) the portable fob determines a first distance between the portable fob and the communication and control unit, and (ii) the communication and control unit determines a second distance between the portable fob and the communication and control unit. The communication and control unit is configured to prevent control of the function of the vehicle if a final distance, determined from the first and second distances, is greater than the predetermined distance.
