Wheel drive motors (8) constituted of electric motors for driving rear wheels (7) are provided on a vehicle body (2) of a dump truck (1). Each wheel drive motor (8) is connected to a main power generator (12) through a bidirectional converter (20) and the like and driven by power supplied from the main power generator (12). A resistor (21) that consumes regenerative power from each wheel drive motor (8) is connected to the bidirectional converter (20). Cooling air is supplied to the resistor (21) from a blower (24). Operations of a switch (23) of the resistor (21) and the blower (24) are controlled by a controller (28). A mode selecting switch (29) for selecting a heating mode (A), a blowing mode (B), and a heating and blowing mode (C) is connected to the controller (28).

Provided are a switching device for an electric vehicle and a method of controlling the switching device. The switching device includes a signal selection part, an inverter, and a controller. The signal selection part receives a first or second switching signal, and selects the first or second switching signal according to a preselected operation mode of the electric vehicle to output the selected switching signal. The inverter performs a direct current/alternating current conversion process on power according to the switching signal output from the signal selection part, and outputs the power. The controller senses an operation mode selection signal for the electric vehicle, and generates a control signal according to the preselected operation mode such that the signal selection part selects the first or second switching signal.

The invention relates to a method for controlling a vehicle drive unit (32) and a vehicle control appliance (10). Said vehicle drive unit (32) comprises at least two individual drives (34, 36) and a vehicle control appliance (10), inside which a continuous torque comparison (24) is carried out between an admissible torque MZul and another torque. The admissible torque MZul is continuously compared with nominal torques MSoll, v (38) and MSoll, E (40) for the at least two individual drives (34, 36).

The invention concerns a hybrid drive chain of a vehicle (1) comprising a heat engine (2) connected to a mechanical assembly (2) including a gearbox (5) coupled with a differential (6) itself coupled with the driven wheels (7G, 7D) of the vehicle (1) by their respective axle shafts (8G, 8D), and at least one electrical machine (3) including a stator (10) and a rotor (11), co-operating with the heat engine (2) via the mechanical assembly to provide heat and/or hybrid traction to the driven wheels (7G, 7D). The invention is characterized in that the electrical machine (3) is arranged between the differential (6) and one of the driven wheels (7D), by surrounding the axle shaft (8D) connecting the driven wheel (7D) to the differential (6).
摘要:
A mixed propulsion system for a seagoing vessel such as a liquid natural gas carrier including a gas turbine engine is described. The vessel has at least one electric propulsion drive and a plurality of prime movers of different types each coupled directly to drive an electrical generator. The outputs of the several generators are connected t at least two electricity distribution switchboards to supply the power requirements of the vessel, and each electric propulsion drive is cross-coupled to receive power selectively from either switchboard such that in the event of a single failure in a switchboard or prime mover or both power can be maintained to both propulsion drives.
摘要:
An engine ECU (280) and an HV_ECU (320) control a throttle motor (296) such that the throttle valve opening degree (TH) does not exceed a prescribed limit (THlim) and a rate of increase (Ta/t) in the throttle valve opening degree is equal to or lower than a predetermined opening degree increase rate (Tb/t) for a predetermined time period after start-up of the engine (120) is initiated. Thus, power output from the engine is controlled so as not to increase significantly for the predetermined time period. Accordingly, while the engine starts up, a shock that can be felt by a driver can be suppressed. In addition, variation in the amount of air taken into the engine when the engine is started is also reduced, which reduces variation in the amount of pollutants in the exhaust gas emitted while the engine starts up.
摘要:
A vehicle control device for a hybrid vehicle, which equipped with at least an internal combustion engine and a rotary electrical machine that reduces the shock that is imparted to a vehicle when the internal combustion engine starts. The vehicle control device detects the running state of the vehicle and, if it is determined that the internal combustion engine will be started, adjusts the ignition timing according to the running state of the vehicle. The control device also improves the responsiveness of the hybrid vehicle when increased acceleration is required.
