摘要： Upon detecting a current balise, an onboard system of a train calculates a speed curve based on measured traveling speed at a timing of the detection and sets a minimum required time period for traveling to each of a next balise and a balise subsequent to the next balise. Upon detecting the next balise, the onboard system compares a traveling time period from the timing of detecting the current balise to the timing of detecting the next balise with the set minimum required time period. The onboard system activates an emergency brake when the elapsed time period is shorter than the minimum required time period to stop the train.

摘要： A method for controlling the distribution of power to a traction motor in a plug-in electric vehicle having a plurality of on-board sources of electric power. Power is distributed at a normal power control relationship in response to an operator control input during operation in a normal mode. Power is depleted at a first rate during operation of the vehicle in the normal mode. Power is distributed at a derate power control relationship in response to the operator control input during operation in a derate mode. Power is depleted at a second rate that is less than the first rate during operation in the derate mode to conserve the power of the one or more on-board sources. Operation in the derate mode can be initiated in response to information from sensors identifying a vehicle condition indicating a battery charge limitation.

摘要： A battery pack including a first subset of battery cells and a second subset of battery cells, set of switches, a DC output port and an AC output port. The battery pack may provide both a DC output signal at the DC output port and an AC output signal at the AC output port by selectively activating the switches of the set of switches. The battery pack may couple the first subset of battery cells and the second subset of battery cells in a parallel configuration or a series configuration.

摘要： A self-propelling trolley assembly has a battery; a wheel driven by an electric motor that is powered by the battery; a rotation position or velocity sensor arranged to sense a rotation position or rotation velocity of the wheel; a user interface; and a control unit to affect a rotation of the wheel according to particular drive modes including a feedback assisted propulsion drive mode; a free-wheeling drive mode; and a rocking drive mode. The drive modes are implemented using different drive voltage patterns to the electric motor, and a stator of the electric motor has a number of stator poles that are not an integer multiple of a number of rotor poles and the stator poles are grouped into at least three magnetically and electrically identical subsets that are mounted sequentially around an angular direction of the electric motor.

摘要： A control device for electric motor vehicle is configured to decelerate by a regenerative braking force of the motor when an accelerator operation amount decreases or becomes zero. The control device detects the accelerator operation amount, calculates a motor torque command value, and controls the motor on the basis of the motor torque command value calculated. The control device detects a speed parameter proportional to a traveling speed and calculates a feedback torque for stopping the vehicle on the basis of the speed parameter detected. The control device also estimates a disturbance torque acting on the motor and converges, as the speed parameter is reduced, the motor torque command value to the disturbance torque on the basis of the feedback torque when the accelerator operation amount decreases or becomes zero and the electric motor vehicle stops shortly. The control device adjusts the feedback torque according to the disturbance torque.

摘要： A method for controlling a drive train with at least one drive unit, in particular for a vehicle is disclosed. A setpoint value for a torque of the at least one drive unit can be predefined. The actual value of this torque is detected and a first signal is generated which ensures reliable operation of the drive train if the deviation of the actual value from the setpoint value is greater than a predefinable absolute value of the deviation value and/or the deviation of the actual value from the setpoint value lasts for longer than a predefinable absolute value of the deviation time period.

摘要： A locomotive throttle controller having a CPU and output driver stage. Such CPU generates an analog voltage based on software logic and transmits to the output driver stage a signal indicative such analog voltage. Such output driver stage receives the signal from such CPU and uses it to provide an analog output voltage signal to a trainline which monitors and/or controls dynamic braking. The improvement therewith of an apparatus, for feeding back from such output driver stage to the CPU an analog signal indicating status of such trainline, comprising a device for obtaining a first analog voltage signal from a node which supplies current to such trainline. A voltage-divider for dividing the first analog voltage signal into a lower range to obtain a second analog voltage signal. A signal generating device connected to receive the second analog voltage signal and generate a third analog voltage signal. A voltage to current converter receives such third analog voltage signal and provides a regulated electrical current signal on an output terminal thereof. A conduction path between such output terminal and CPU is provided. A converter in such CPU converts the electrical current signal into a fourth analog voltage signal. A comparator in such CPU compares such fourth analog voltage signal with the analog voltage based on software logic and an error signal generator in such CPU generates and utilizes an error signal indicating inconsistency between such fourth analog voltage signal and the analog voltage based on software logic.
