摘要： A power source system mounted in a vehicle includes: a first power source (2); a first load (41) operated by electric power supplied from the first power source (2); a first controller (9) that controls an operation of the first load (41) by a first program; a second power source (8) connected to the first power source (2) via a converter (7); a second load (11) operated by electric power supplied from the second power source (8); a second controller (10) that controls an operation of the second load (11) by a second program; an electric power disconnecting device (3) that connects or disconnects between the first power source (2) and the first load (41); and a third controller (12) that controls the electric power disconnecting device (3). When the first program is changed, the third controller (12) disconnects the first power source (2) from the first load (41) by the electric power disconnecting device (3) before a change process of the first program is started.

摘要： A cart may include a driving wheel, a motor configured to rotate the driving wheel, a motor drive circuit configured to drive the motor, a motor brake circuit configured to electrically brake the motor, a control device configured to control the motor via the motor drive circuit and the motor brake circuit so that a travelling speed of the cart becomes equal to or lower than an upper limit travelling speed, and a temperature sensor configured to detect a temperature of the motor brake circuit. The control device may be configured to change the upper limit travelling speed to a second upper limit travelling speed lower than the first upper limit travelling speed when the upper limit travelling speed is a first upper limit travelling speed and the temperature detected by the temperature sensor exceeds a first predetermined temperature.

摘要： A system and method for controlling a six-phase machine include generating a plurality of control vectors for the six-phase machine. The six-phase machine is configured as a combination of a first three-phase machine and a second three-phase machine. Each of the plurality of control vectors is generated by combining two phase vectors from the six-phase machine, where one phase vector is selected from the first three-phase machine and another phase vector is selected from the second three-phase machine. The system and method also include implementing a control method based on the plurality of control vectors to control the operation of the six-phase machine.

摘要： A power control system comprises a battery system including N battery packs. A plurality of contactors selectively connects N battery packs of a battery system in a first configuration supplying a first voltage level, a second configuration supplying a second voltage level, and a disconnected configuration. M power inverters connect the battery system to M electric machines, respectively. A controller is configured to determine when to transition between the first configuration and the second configuration. The controller is configured to transition between the first configuration and the second configuration by causing one of a positive torque transient and a negative torque transient to be generated by at least one of the M electric machines, transitioning the battery system from one of the first configuration and the second configuration to the disconnected configuration, and transitioning from the disconnected configuration to the other one of the first configuration and the second configuration.

摘要： There is provided an electrically driven vehicle that well balances calculation volumes and communication volumes of two control devices configured to drive and control motors for driving. The electrically driven vehicle comprises at least one motor for driving and a first control device and a second control device configured to control the motor. The first control device is configured to calculate a target torque that is to be output from the motor, based on information including an accelerator position, to calculate a current command based on the calculated target torque, and to send the calculated current command to the second control device. The second control device is configured to use the current command, a phase current of the motor and a rotational angle of the motor such as to drive the motor by feedback control.
