摘要： When a calibration starting condition of a pressure sensor is satisfied while a fuel cell vehicle is traveling, the fuel cell vehicle starts to travel by using electric power supplied from a secondary battery. In the fuel cell vehicle, a pressure sensor is calibrated based on hydrogen pressure in a hydrogen gas flow channel downstream of a pressure reducing valve after a shut-off valve of a hydrogen tank is closed, and the hydrogen in a hydrogen gas flow channel is exhausted until hydrogen pressure upstream of the pressure reducing valve and hydrogen pressure downstream of the pressure reducing valve become substantially equal to each other. The fuel cell vehicle travels by using electric power supplied from the secondary battery while the pressure sensor is being calibrated, so that calibration processing of the pressure sensor can be performed without causing a noise.

摘要： A driving device includes a motor, an inverter configured to drive the motor by switching a plurality of switching elements, and an electronic control unit configured to set voltage commands of phases according to temporary voltage commands of the phases based on a torque command of the motor and perform switching control of the switching elements by generating PWM signals for the switching elements by using the voltage commands of the phases and a carrier voltage. The electronic control unit is configured to switch a method of setting the voltage commands between a first method and a second method for each irregular time interval. The first method is a method of setting the voltage commands without superposing harmonics to the temporary voltage commands, and the second method is a method of setting the voltage commands by superposing the harmonics to the temporary voltage command.

摘要： A pulse width modulation (PWM) Frequency Adaptation Mechanism (PFAM) is configured to receive vehicle state input, and in response to the vehicle state input, provide a PWM parameter for PWM switching of electronics in a power conversion circuit of an electric drive system (EDS) for a hybrid electric vehicle. In one example, a PWM parameter that reduces the audible noise generated by PWM switching can be designated by the PFAM. A PFAM can be configured to receive user input regarding user preference for a default mode or a noise reduction mode. Vehicle state input can include input related to vehicle motion, climate control system state, engine state, EDS state, vehicle body state and audio system state. By way of example, a PWM noise reduction parameter can comprise a high PWM switching frequency, or a random frequency hopping about a low PWM switching frequency.

摘要： In a motor drive control system configured to include a converter capable of stepping up the voltage, when the locked state of MG2 operating as an electric motor does not occur (NO in S130), a voltage command value VHref for the converter output voltage is set according to respective required voltages of MG1 operating as an electric generator and MG2 (S140). In contrast, when the locked state of MG2 occurs (YES in S130), the voltage command value VHref is set to a limit voltage Vlmt or less for limiting the voltage step-up by the converter (S150, S180). When the locked state occurs, the converter output voltage is decreased and accordingly the DC voltage switched by the inverter is lowered, so that a switching loss at the switching device forming a part of the inverter is reduced and the temperature increase due to the heat generation can be suppressed.

摘要： A motor drive control device is capable of reducing gear rattling noise generated in a speed reducer without increasing size of the speed reducer and the number of components. A motor ECU controls a motor to generate a reverse set torque (Tn) when a target torque (T*) is reversed (at a time t1). The motor ECU sequentially calculates a backlash (B) in a counter gear mechanism, and sets a time period (D1) in which the reverse set torque (Tn) is generated by the motor and a time period (D2) in which a return set torque (Tp) is generated by the motor so that the backlash (B) at a current time becomes equal to a time integrated value (corresponding to an area A) of an estimated relative velocity (V2−V1) until a time of re-abutment.

摘要： A vehicle capable of being externally charged, in which a vehicle-mounted power storage device is charged using electric power supplied from a charging cable external to the vehicle, an ECU executes a smart verification process for communicating with an electronic key located within a prescribed verification range and verifying whether the electronic key is an authorized user's key or not, when it is detected that a user has operated a switch for locking the charging cable. When smart verification is impossible, the ECU executes a noise suppression process caused by external charging, and executes the smart verification process during the noise suppression process. When it is determined by the smart verification process during the noise suppression process that smart verification is possible, the ECU switches a state of a lock mechanism of the charging cable.
