Abstract: In a hybrid vehicle control apparatus, a motor control unit executes the input power control on a MG unit independently from a torque control on an AC motor so that the input power control and the torque control are stabilized. The motor control unit further executes a torque difference reduction control, which controls current vector of the AC motor, to reduce a torque difference to zero substantially thereby preventing uncomfortable torque variation in a transient condition of input power control of the MG unit. The torque difference is calculated based on a first estimated torque calculated from a detected motor torque of the AC motor and a second estimated torque calculated from a command current vector for torque control of the AC motor.

Abstract: In electric vehicle control, system voltage stabilization control is executed to reduce the difference between a target value and detected value of a system voltage generated by a voltage boosting converter for an AC motor. Further, conversion power control is executed to reduce the difference between a command value and detected value of the conversion power, which is defined as the output power of the voltage boosting converter. A conversion power correction quantity is computed from an input power operation quantity of the system voltage stabilization control and reflected in the conversion power control to correct the conversion power. Thus, variations in a system voltage caused by an error or the conversion power control can be reduced.

Abstract: A motor control unit controls the input electric power of a MG unit to thereby suppress variations of a system voltage and stabilize the system voltage. The torque control of an AC motor and the input electric power control of the MG unit are executed independently from each other, so that the torque control and the input electric power control are stabilized. Further, torque variation zeroing control for correcting a phase of a pulse waveform voltage is executed so that a difference between a first estimated torque computed based on a torque control detection current vector of the AC motor and a second estimated torque computed based on a detection motor current vector is reduced to zero. Thus, uncomfortable torque variation is suppressed in a transient condition of the input electric power control of the MG unit.

Abstract: A position detector for detecting the piston TDC position in a piston engine has a cylindrical casing penetrating the top wall defining a combustion chamber of the engine and fixed thereto, a light emission element, a light reception element each being accommodated within the upper half of the casing, an inlet optical fiber connected to the light emission element and an outlet optical fiber connected to the light reception element. These optical fibers are inserted into the lower half of the casing. The lower end of each optical fiber is opposed to the upper surface of the piston at a predetermined distance therefrom when the piston is located in the vicinity of the TDC position. The light emitted by the light emission element is applied to the upper surface of the piston, after passing the inlet optical fiber. The reflected light from the upper surface of the piston is received and sent to the light reception element by the outlet optical fiber. The light reception element transmits a light reception signal corresponding to the amount of the received light to the detecting circuit. The detecting circuit detects peaks of the light reception signal, which appear before and after the piston TDC position, calculates the half of the rotating angle of a crankshaft between two adjacent peaks and transmits a TDC piston detecting signal when the crankshaft rotates by the calculated rotating angle from the time the preceding peak out of two adjacent peaks appearing in the following period is detected.
