Abstract: A system includes a transmitter of a radar system to transmit transmitted signals, and a receiver of the radar system to receive received signals based on reflection of one or more of the transmitted signals by one or more objects. The system also includes a processor to train a neural network with reference data obtained by simulating a higher resolution radar system than the radar system to obtain a trained neural network. The trained neural network enhances detection of the one or more objects based on obtaining and processing the received signals in a vehicle. One or more operations of the vehicle are controlled based on the detection of the one or more objects.

Abstract: A system for detecting and mitigating window condensation for a vehicle includes an interior camera and a heating, ventilation, and air conditioning (HVAC) system. The system also includes a controller in electrical communication with the interior camera and the HVAC system. The controller is programmed to determine an opacity of a first window of the vehicle using the interior camera, compare the opacity of the first window to an opacity threshold, and adjust the HVAC system to decrease the opacity of the first window of the vehicle in response to determining that the opacity of the first window is greater than or equal to the opacity threshold.

Abstract: A method for control of an alternating current (AC) electric motor through a voltage inverter having a plurality of electric switches with on-off states that collectively define a plurality of non-zero vectors angularly disposed about a common origin includes through one or more controllers, calculating a rotating voltage reference vector to apply to the AC electric motor through the voltage inverter. The method also includes through one or more controllers, calculating voltage inverter switching times using a first subset of the plurality of non-zero vectors, the first subset including fewer than all of the plurality of non-zero vectors and including no adjacent non-zero vectors, to synthesize the rotating voltage reference vector. Additionally, the method includes through the voltage inverter, applying the rotating voltage reference vector to the AC electric motor.

Abstract: A torque transfer assembly including a drive shaft with external splines. A first proximal groove and a first distal groove of the drive shaft are spaced apart at a first distance. A driven member includes a hub configured to receive the drive shaft. The hub includes internal splines, a second proximal groove, a second distal groove, and a slit. The second proximal groove and the second distal groove are spaced apart at a second distance equal to the first distance. A first retention member is configured to be inserted into the slit and into cooperation with the first proximal groove when the drive shaft is seated in the hub. The first distal groove of the drive shaft aligns with the second proximal groove of the hub when the drive shaft is within the hub such that the first proximal groove of the drive shaft is aligned with the slit.

Abstract: A system for detecting and warning a user of an object in a path of a vehicle includes a detection module configured to detect an object in a path of a vehicle, and a control module in communication with the detection module. The control module is configured to receive vehicle data from one or more vehicle sensors, determine a height of the detected object, determine a ground clearance of the vehicle based on the received vehicle data, and in response to the height of the detected object being greater than a threshold based on the ground clearance of the vehicle, generate a signal to notify the user of the detected object. Other examples systems and methods for detecting and warning a user of an object in a path of a vehicle are also disclosed.
