摘要： A vehicle driving apparatus, configured to drive a vehicle including first and second wheels, includes first and second motors, first and second power transmission mechanisms, and a controller. The first motor is configured to generate first driving torque that rotates the first wheel. The second motor is configured to generate second driving torque that rotates the second wheel in a direction same as a direction in which the first wheel is rotated. The first and second power transmission mechanisms are configured to transmit the first and second driving torque from the first and second motors to the first and second wheels, respectively. The controller is configured to perform torque distribution control in a case where a gear rattle occurrence condition is satisfied. The torque distribution control drives the first motor to thereby decrease the first driving torque and drives the second motor to thereby increase the second driving torque.

摘要： A vehicle includes an inverter, a motor, a transmission, and a modulator. The inverter performs pulse width modulation processing at a predetermined carrier frequency. The motor is supplied with electric power from the inverter. The transmission changes the number of revolutions of the motor, and transmits rotary power of the motor to one or more driving wheels. The modulator controls the pulse width modulation processing performed by the inverter, and changes the carrier frequency of the pulse width modulation processing, to offset a change in a frequency of a sideband component out of frequencies of a carrier sound. The carrier sound is generated in the motor or the inverter, or both, accompanying a stepwise change in the number of revolutions of the motor on a condition that the stepwise change is made by the transmission.

摘要： A vehicle power supply includes an electric accumulator pack, an electric motor, first and second switches, an output determiner, and a switch controller. The electric accumulator pack includes first and second electric accumulators. The first and second switches are controlled between on- and off-states. The output determiner determines whether the first electric accumulator is in a first output state or a second output state, and whether the second electric accumulator is in the first output state or the second output state. If at least one of the first electric accumulator or the second electric accumulator is in the first output state, the switch controller controls either one of the first and second switches to the on-state, and the other switch to the off-state. If both the first and second electric accumulators are in the second output state, the switch controller controls both the first and second switches to the on-state.

摘要： An onboard device includes a first cover member having a first abutment surface, a second cover member having a second abutment surface abutting on the first abutment surface and an internal space for housing an electrical apparatus with the first cover member, a transmission portion that is formed in one or both of the first and second cover members, extends, from the first and second abutment surfaces, outward in an abutment direction in which the first and second abutment surfaces abut against each other and transmits sound more easily from the internal space to outside of the first and second cover members than adjacent regions in the first and second cover members, and a soundproof cover that has a through-hole penetrating in the abutment direction. The first abutment surface, the second abutment surface, and the transmission portion are located inside the through-hole.
