Автор: Frank F. Lipski
Принадлежит: FAZER Tech CORP

A supplemental propulsion system for a vehicle includes an electrical generator coupled to the vehicle's engine. At least one electric motor is coupled to one or more propulsion devices, such as road wheels of a motor vehicle. Electrical power from the generator is supplied to an electronic control unit that then supplies electric power to the electric motor. The system may be configured to be retrofitted to a conventional gasoline or diesel-powered vehicle.

The invention relates to a brushless motor drive device that performs switching determination of energization modes of a three-phase brushless motor according to a sensorless method, and a drive method thereof. A pulse induced voltage induced in a non-energized phase of three phases by a pulse voltage is compared with a threshold to determine the switching timing of the energization modes. Here, by limiting a duty ratio of a voltage application to equal to or greater than a lower limit, a situation in which the pulse induced voltage is sampled while the pulse induced voltage is oscillating is avoided, and a situation in which the pulse induced voltage falls below a voltage detection resolution is avoided. As a result, determination of energization mode switching timing based on a pulse induced voltage can be performed more stably.

A control device for a motor drive system including an AC motor having a magnet in a rotor, a converter, and an inverter generates a step-up command value for the converter based on a torque command value for the AC motor. The control device determines whether or not to carry out field-weakening control for increasing a current in a direction weakening force of a magnet that is supplied from the inverter to the AC motor, based on the step-up command value and a state of drive of the AC motor. When field-weakening control should be carried out and when an absolute value of the torque command value is smaller than a threshold value, the control device further increases the generated step-up command value. By doing so, an amount of a field-weakening current can be decreased and therefore efficiency of the motor drive system can be improved.

A drive system with one or more electrically driven axles, a transmission subsystem, which is drivingly coupled to a drive gearbox of each of the electrically driven axles, first and second motors, which are each drivingly coupled to the transmission subsystem and have different motor characteristics, and a controller. The drive gearbox of each axle transmits rotary power to an associated set of vehicle wheels. The controller controls the first and second motors responsive to at least a torque request. Over a significant portion of the operating range of the drive system, the controller is configured to vary the respective magnitudes of the rotary power provided by the first and second motors to satisfy the torque request in a manner that maximizes a combined efficiency of the motors in a predetermined manner. 1. A drive system for a vehicle , comprising:one or more electrically driven axles, each of the one or more electrically driven axles having a drive gearbox that is adapted to transmit rotary power to an associated set of vehicle wheels to propel the vehicle;a transmission subsystem drivingly coupled to the drive gearbox of each of the electrically driven axles;first and second motors that are each drivingly coupled to the transmission subsystem, wherein the first and second motors are different from one another; andan electronic controller configured to control the first and second motors to satisfy a torque request, the electronic controller having a memory with a plurality of first blending maps or look-up tables, the first blending maps or look-up tables each being associated with a different magnitude of a speed parameter that is related to a speed of the vehicle, each of the first blending maps or look-up tables being configured to determine fractional portions of the torque request to be produced by the first and second motors that are based on a magnitude of the torque request.2. The drive system of claim 1 , wherein the first motor comprises a ...

Provided is a traveling control device capable of appropriately controlling the turning and the speed of a traveling vehicle. A traveling control device of a traveling vehicle including a traveling control unit having a pair of left and right configurations capable of respectively driving a pair of left and right driving wheels includes: an instruction receiving portion that receives an operation instruction directed to each of the pair of left and right driving wheels; a speed instruction value calculation portion that calculates a speed instruction value that is to be instructed to the traveling control unit, based on each of the operation instructions; an operation instruction determination portion that determines, based on each of the operation instructions, whether the operation instruction is an operation instruction to rotate the pair of left and right driving wheels in the same direction as each other, or an operation instruction to rotate the pair of left and right driving wheels in different directions from each other; and a speed instruction value correction portion that corrects, if the operation instruction is an operation instruction to rotate the pair of left and right driving wheels in the same direction as each other, one of the speed instruction values calculated for the traveling control unit by the speed instruction value calculation portion, based on the other speed instruction value.

A method for operating a storage-and-retrieval unit ( 3 ) is specified, in which a rail line ( 1 )/power-supply rail ( 6 ) is set to a hazard-operation voltage when a risk posed by the storage-and-retrieval unit ( 3 ) is detected. In the storage-and-retrieval unit ( 3 ) the level of the voltage applied to the rail line ( 1 )/power-supply rail ( 6 ) is measured and a current path between the rail line ( 1 )/power-supply rail ( 6 ) and a drive motor ( 5, 5 a . . . 5 c ) of the storage-and-retrieval unit ( 3 ) disconnected when the voltage measured is below a threshold value associated with a hazardous situation or emergency. Furthermore, a storage-and-retrieval unit ( 3 ) as well as an automated rack storage system for performing the proposed method is specified.

Принадлежит: Dr Ing HCF Porsche AG

A motor vehicle has a high-voltage battery ( 11 ) and two separate electric machines. Each electric machines is associated with a power electronics unit ( 13, 14 ), and each power electronics unit ( 13, 14 ) has a DC-to-DC converter ( 13 — 1, 14 — 1 ). Each DC-to-DC converter ( 13 — 1, 14 — 1 ) is designed to reduce a high voltage of the high-voltage battery ( 11 ) to a predetermined voltage. The two DC-to-DC converters ( 13 — 1, 14 — 1 ) of the two power electronics units ( 13, 14 ) are connected electrically in parallel and are set to different voltage values.
