Abstract: Methods and systems are provided for controlling the operation of an air charging system of an internal combustion engine. A plurality of actuators include an electric motor of an air compressor. Output parameters of the air charging system are monitored by a plurality of sensors. An error between each one of the output parameters and a target value thereof is calculated by a processor. The calculated errors are applied to linear controllers that yield virtual inputs. Input parameters for the air charging system are calculated using the virtual inputs. The input parameters affect all of the output parameters. The input parameters are calculated with a non-linear mathematical model of the air charging system, configured such that each one of the virtual inputs is in a linear relation with only one of the output parameters. The actuators are operated using the input parameters.

Abstract: A discharge control system of a vehicle includes a traction power inverter module (TPIM) configured to convert a first direct current (DC) voltage output by a first battery to alternating current (AC) power and apply the AC power to an electric motor. An accessory power module (APM) is configured to convert the first DC voltage into a second DC voltage of a second battery. A voltage calculation module is configured to, when the first DC voltage is less than an operation threshold voltage of the APM, determine the second DC voltage based on a function of the first DC voltage and the operation threshold voltage. A diagnostic module is configured to indicate whether a discharge fault is present. A discharge control module is configured to, when the discharge fault is present, based the first DC voltage and the second DC voltage, selectively control operation of the TPIM and the APM.

Abstract: A vehicle, a radar system for the vehicle, and method of driving the vehicle. A radar array having plurality of radar nodes is arranged along the vehicle. Each radar node includes a first transmitter at one end of the node, a second transmitter at a second end of the node and a plurality of receivers aligned between the first transmitter and the second transmitter. At least one of an aperture length of the nodes and a spacing between the nodes is a variable parameter. A processor activates a transmitter of the radar array to generate a test pulse, receive, at a receiver of the radar array, a reflection of the test pulse from an object, and determines an angular location of the object from the reflection of the test pulse. A trajectory of the vehicle can be changed using the determined angular location of the object.
