摘要： A method for controlling a braking torque of a drive system and for braking a vehicle includes in a first state connecting phase connections of a synchronous machine to one another by a changeover apparatus and short circuiting the phase connections such that a first braking torque develops at the synchronous machine. In a second state the phase connections are connected to one another by the changeover apparatus and to a resistance, such that a second braking torque develops at the synchronous machine. The changeover apparatus periodically switches between the first and second states at a switching frequency of 10 Hz or higher to produce a pre-settable braking torque at the synchronous machine, with the changeover between the first state and the second state being controlled by a timing element in an unregulated manner.

摘要： Even in the case in which an overvoltage is generated when a vehicle is in a non-operation state, the overvoltage can be suppressed. A power conversion device is connected to a three-phase motor mounted on a vehicle and includes an inverter circuit, a gate drive substrate, and a motor control substrate. In the motor control substrate, when the vehicle is in the non-operation state and a regenerative voltage applied from the three-phase motor to the inverter circuit becomes equal to or more than a predetermined threshold value, a power supply circuit supplies operation power to a control circuit. The control circuit starts when the operation power is supplied from the power supply circuit and outputs gate control signals to a driver circuit of the gate drive substrate, such that regenerative energy according to the regenerative voltage is consumed between the three-phase motor and the inverter circuit.

摘要： A diesel-electric drive system includes a generator having two multi-phase winding systems, a diesel engine, and a DC-link converter. Two self-commuted pulse power converters on the generator side are linked to the windings systems and to each other by a brake resistor on the alternating voltage side. The brake resistor is split into two series-connected resistors, each having half the resistance value of the brake resistor. An input of a bipolar switching device is connected to a connecting point of two series-connected resistors. The capacity of the diesel motor can then be checked in a self-load test with a controllable load torque of the diesel-electric drive system, while eliminating overloads of the power semiconductors of the self-commuted pulse power converters on the generator side.

摘要： An apparatus and method for controlling a braking-force distribution in a vehicle collision is used in a vehicle including at least one electric storage device and at least one motor-generator for driving and braking. When the vehicle decelerates or stops in response to a brake operation, regenerative cooperative brake control is performed in which a braking force of a frictional brake is reduced or eliminated while a braking force of a regenerative brake applied by the motor-generator is increased by an amount corresponding to the reduction in the braking force of the friction brake. When the vehicle collides, the apparatus reduces the braking force of the regenerative brake applied by the motor-generator and increases the braking force of the friction brake.
