Abstract: Systems and methods are disclosed for prioritizing vehicle charging using energy from renewable/low carbon emission energy sources over non-renewable/high carbon emission energy sources. The proposed systems and methods allow users to identify when to charge their vehicles and/or when to provide energy from their vehicles to other structures based on a currently available energy source mixture and in a manner that minimizes the impact to the environment. In-vehicle connectivity may be utilized to obtain real-time grid information, and a charging schedule may then be created that intelligently prioritizes charging during times when an energy mixture percentage available from renewable/low carbon emission sources exceeds a predefine threshold or when a real-time emissions level is below a predefined threshold.

Abstract: A vehicle includes an electrical powertrain, a heater, at least one cooling loop, and a controller. The heater is configured to heat a vehicle cabin. The at least one cooling loop is configured to transport waste heat from at least one subcomponent of the electrical powertrain to the vehicle cabin. The controller is programmed to, in response to a command to heat the vehicle cabin and a command to operate in an economy mode, shut down the heater and operate the at least one cooling loop to transport the waste heat to the vehicle cabin. The controller is further programmed to, in response to the command to heat the vehicle cabin and an absence of the command to operate in the economy mode, operate the heater to heat the vehicle cabin.

Abstract: A vehicle control system may include a sensor network sensing vehicle attitude information and a controller operably coupled to the sensor network to determine, based on the vehicle attitude information, movement of a center of gravity of the vehicle relative to an axis of rotation of the vehicle.

Abstract: A controller detects a rotor magnet temperature based on an actively detected back electromotive force (BEMF) voltage of the motor. The controller detects the BEMF voltage by commanding the injection of a direct-axis (d-axis) current into the motor while the motor is spinning but otherwise commanding no torque. The controller actively detects the BEMF voltage in that the controller purposely injects a known quantity of d-axis current at a chosen time during which the controller detects or is aware that the motor is commanding no torque. Using a quadrature-axis (q-axis) voltage equation, which describes the relationship between a voltage command, the current, the BEMF voltage, and reactance in the q-axis, the controller solves for the BEMF voltage with the voltage command, the current, and the q-axis reactance being known to the controller. The controller detects the rotor magnet temperature based on the BEMF voltage.
