摘要： An ECU sets target value of a system voltage based on an electric power loss of a motor generator and an inverter and controls a voltage boost converter. The ECU calculates the target value of the system voltage using a function expression generated, for each operating point of the motor generator, by approximating a loss characteristic which represents change of the electric power loss with respect to change of the system voltage, by a quadratic expression or a linear expression of the system voltage.

摘要： When an electric vehicle outputs a torque instruction, firstly, a request torque is acquired and a judged whether the acquired request torque is positive or negative. Regardless of the sign of the request torque, it is judged whether the eco-switch is ON. If the request torque has a positive sign and the eco-switch is OFF, a map A is selected. If the eco-switch is ON, a map B which limits the maximum torque to a low value for the map A is selected. If the request torque has a negative sign, a map C is selected regardless of the eco-switch ON/OFF state and the maximum torque is not limited.

摘要： A plurality of current sensors are provided to correspond to a plurality of inverter circuits for driving a plurality of motor generators, respectively. Zero point adjustment of each current sensor is executed in a non-energized state recognized based on a stop of operation of the corresponding inverter circuit and when noise influence is determined to be small based on stops of operations of the other inverter circuits in the same casing. As a result, it is possible to avoid a risk of performing the zero point adjustment in a state in which an output of the current sensor is not exactly a value corresponding to zero current due to the noise influence from the other inverter circuits. In this way, it is possible to highly accurately execute the zero point adjustment of the current sensor for measuring motor driving current.

摘要： A motor drive device (100) includes a boost converter (12) boosting a power supply voltage and outputting a boosted voltage; an inverter (14) receiving the boosted voltage from the boost converter (12) and driving a motor (M1); and a controller (30) giving a target value of the boosted voltage to the boost converter (12) and setting one of a rectangular-wave control and a non-rectangular-wave control as a control method of the inverter (14).

摘要： In one coordinate system of arbitrary rectangular coordinate systems including a coordinate system in which the position of a stator is fixed, a coordinate system in which the position of a rotor is fixed, and a coordinate system which rotates at a rotational frequency which is n times (n is an integer which is not 0 or 1) that of the rotor, a filter on any other coordinate system is defined. Further, driving of a motor is controlled by utilizing this filter. As a result, a coordinate transformation operation need not be individually performed with respect to control variables.
