摘要： In a hybrid vehicle provided with a power dividing mechanism comprising a clutch mechanism, an ECU performs speed-change control. In the control, the ECU performs an engage preparing process if it is necessary to engage clutch plates of the clutch mechanism with each other. In the process, the ECU switches a reference value which is referred in a feedback control for performing a rotation synchronization and a position synchronization for the clutch plates from a calculated value which is calculated from a pulse signal of first rotational sensor mounted the clutch plate to an estimated value which is estimated from a pulse signal of each of second and third rotational sensors for detecting rotational speed of each motor generators if clutch rotational speed as rotational speed corresponding to the clutch plate as an engagement element decreases to less than a criterion value.

摘要： When an engine is operated, a power dividing mechanism divides power of the engine to output the power to a motor for running operation and a motor for a cargo handling operation, respectively. Each of loads is driven via a rotational shaft of a corresponding one of the motors. By operating the engine and supplying the motors with electric power from a battery to operate the motors, each of the loads can also be driven by the sum of power of the engine and power of a corresponding one of the motors. When surplus power is generated in the power of the engine, each of the motors is operated as an electric power generating unit by the surplus power. As a result, the battery is charged.

摘要： To accurately detect a resonance frequency of tire even in high speed range by which tire air pressure state of each wheel is known, a calculation processing unit to which detection signals of wheel speed and resonance frequencies of tire are inputted calculates a timewise change amount of a wheel speed deviation that is a difference between wheel speed ratios of front and rear wheels. Then, it makes corrections to remove the influence of timewise change amounts of resonance frequencies of front wheels from timewise change amounts of wheel speed deviations based on a relationship between the resonance frequency and the wheel speed deviation when air pressure of the tire is changed. The unit then converts the corrected timewise change amount of the rotational state into the timewise change amount of the resonance frequencies of the rear wheels based on the above-described relationship and the resonance frequencies of the rear wheels and the timewise change amounts of the resonance frequencies of the rear wheels which have been accurately detected before the vehicle speed exceeds an upper limit value.

摘要： According to input parameters, a controller carries out: generation of a voltage command value for each of d- and q-axes; conversion of the voltage command value for each of the d- and q-axes into a voltage command value for each of the multiphase windings; and control of a multiphase inverter based on the voltage command value for each of the multiphase windings. The controller adds, to the voltage command value for the q-axis, a first compensation voltage value for compensating torque ripples to thereby output a compensated voltage command value for the q-axis. The first compensation voltage value contains m-th harmonic components in the AC motor and varies depending on the rotational angle of the rotor, the m corresponding to the number of phase of the multiphase windings. The controller uses, as the voltage command value for the q-axis, the compensated voltage command value for the q-axis.
