摘要:
A control system for a vehicle comprises a control unit configured to be electrically coupled to a drive system of the vehicle. The drive system includes at least one traction motor for providing motive power to the vehicle. The control unit is configured to control a torque output of the traction motor to hold zero speed or near zero speed of the vehicle on a grade without knowing information, in at least one mode of operation, about the grade and/or a load of the vehicle, and without a service brake of the vehicle being activated.

The invention relates to a charging device including a reversible AC/DC converter enabling power to be supplied to two outlets that have different voltages. Said charging device is particularly suitable for use as an on-board electric motor vehicle device. The device enables power to be supplied to both a traction battery, at a relatively high voltage, and apparatuses from the very low-voltage grid. Said device has a small overall size and low weight. The invention rests on a DC/DC converter (in the AC/DC converter) having multiple reversible outlets that includes a single transformer.

Provided is an electric vehicle control device in which a power supply device has a simple structure. A BMU power supply device (110) lowers a battery voltage to be suitable for the control voltage of a BMU (109). A flyback down-regulator (80) lowers the battery voltage to be suitable for an input of a CPU power supply device (111) which forms a control voltage for a CPU (108). A contactor (90) is disposed on a plus-side line which connects a battery (40) to a motor drive circuit (100), and is opened and closed in response to an instruction from the CPU (108). Control power for the down-regulator (80) is formed by the BMU power supply device (110), and a main switch (113) is disposed to open and close a path through which the voltage of the control power is input to the down-regulator (80).

The invention relates to supplying electric traction motors of a rail vehicle with electrical energy. Internal combustion engine/machine combination are operated such that alternating current is generated and used for operating at least one electric traction motor, in a first operating state of the machine in a generator mode. In a second operating state of the machine, an associated machine converter supplies alternating current and drives the associated internal combustion engine, wherein at least the machine converter associated with the second electrical machine is supplied, while the associated electrical machine is in the second operating state, via an electrical DC voltage line with direct current by a rectifier associated with the first machine, wherein the rectifier produces the direct current from alternating current generated by the first electrical machine.

A vehicle power supply apparatus includes: a switching element; a DC-DC converter; and a control unit. When a vehicle is travelling, and a generator does not generate electricity, if a voltage of an electricity storage unit is greater than a predetermined value, the control unit turns on the switching element, and controls driving of the DC-DC converter such that the electricity storage unit discharges electricity to supply electric power of the electricity storage unit to loads, and even if the voltage of the electricity storage unit decreases to the predetermined value, as long as the vehicle speed is greater than or equal to a threshold value, the control unit turns on the switching element, and controls the driving of the DC-DC converter such that the electricity storage unit discharges electricity to supply the electric power of the electricity storage unit to the loads.

A harness routing structure for an electric vehicle is provided with a floor panel, a below-floor component, an above-floor component and a harness. The floor panel partitions a cabin space and a below-floor space. The floor panel has a harness through-hole. The below-floor component is disposed below the floor panel. The above-floor component is disposed above the floor panel and further toward a front of the vehicle than the below-floor component. The harness electrically connects the below-floor component and the above-floor component. The harness runs through the through-hole. The harness through-hole is located, with respect to a vehicle-lengthwise direction of the floor panel, in an intermediate position between a below-floor harness connection position of the below-floor component to a first end of the harness and an above-floor harness connection position of the above-floor component to a second end of the harness.

A method, device, and system for surge current protection on a circuit including a three-phase inverter and a capacitive load. The inverter can be controlled to connect the capacitive load with different direct current voltage potentials. In a pre-charging mode, the capacitive load is connected with the a first direct current voltage potential via a current-limiting element to limit a start-up current. In a normal operating mode following the pre-charging mode, the inverter is controlled to directly connect the capacitive load with the different direct current voltage potentials.

Provided is a fixing structure of an electric apparatus in an engine compartment provided in a front portion of a vehicle. The fixing structure includes a tray, a removal mechanism, and a protecting plate. The tray is fixed in the engine compartment and configured such that the electric apparatus is placed thereon. The removal mechanism is configured to remove the electric apparatus from the tray when the electric apparatus receives a predetermined impact force or more from a front side of the vehicle. The protecting plate is attached to the electric apparatus, and is configured to abut with a structural object placed at a rear side of the vehicle relative to the electric apparatus when the electric apparatus is removed from the tray due to the impact force so as to move rearward.
