摘要： A vehicle having at least one electric machine capable of propelling the vehicle is provided. An oil circulation path is provided that circulates oil through the electric machines. A controller commands the electric machines to fulfill torque demands. The controller utilizes the oil temperature in the oil circulation path in order to control the commanded torque output by the electric machines. In the event of a failure or fault in the oil temperature sensors, the controller estimates the oil temperature from the temperature of coils within the electric machine. The estimated oil temperature is utilized instead of the sensed oil temperature to control the torque outputs to maintain torque demands.

摘要： A vehicle includes one or more inverter-fed electric machines such as permanent magnet synchronous motors. In response to a torque request, a controller issues commands to an inverter calculated to cause the motor to produce the requested torque. A method of operating the inverter may determine the commands based on the ratio of rotor speed to inverter input voltage, reducing the approximation error associated with multi-dimensional lookup tables. When the speed and voltage vary while maintaining a constant ratio and constant torque request, the issued commands produce a winding current in the electrical machine with constant direct and quadrature components.

摘要： A vehicle comprises an electric machine configured with at least one controller issuing torque commands with the use of a voltage bus. The controller may be configured to respond to a torque requests based on multiple vehicle system inputs including vehicle speed, position of the accelerator pedal and brake pedal, and various other vehicle data. The controller may respond to a torque request that exceeds a threshold value by issuing torque commands for the electric machine based on a speed of the electric machine and a voltage on the bus. Based on the speed of the electric machine and voltage on the bus, the controller may issue a constant torque output by the electric machine as the speed and voltage vary. Calculating a ratio using speed of the electric machine to voltage on the bus to determine torque capability may result as a constant torque when the ratio is constant.

摘要： A vehicle includes one or more inverter-fed electric machines such as permanent magnet synchronous motors. A controller operates an inverter in either six-step mode or PWM mode depending upon motor speed, motor torque, and the inverter input voltage. A method of selecting the operating mode may determine a transition threshold based on the ratio of rotor speed to inverter input voltage, reducing the approximation error associated with multi-dimensional lookup tables. When the speed and voltage vary while maintaining a constant ratio and constant torque, the transition threshold does not change. Consequently, the controller remains in the same mode.

摘要： A vehicle includes one or more inverter-fed electric machines such as permanent magnet synchronous motors. In response to a torque request, a controller issues commands to an inverter calculated to cause the motor to produce the requested torque at the current temperature. A method adjusts the direct component of the winding current such that the requested torque is delivered efficiently. For a given rotor speed, bus voltage, and torque, the direct component increases as the temperature increases.
