With reference to following description and attached drawing, it will be clear that these and other aspects of the embodiment of the present invention.In these descriptions
In attached drawing, some particular implementations in the embodiment of the present invention are specifically disclosed, to represent to implement the implementation of the present invention
Some modes of the principle of example, but it is to be understood that the scope of embodiments of the invention is not limited.On the contrary, the present invention
Embodiment includes falling into all changes, modification and the equivalent in the range of the spirit and intension of attached claims.
Engine according to embodiments of the present invention and the shared cooling system of braking resistor are described below in conjunction with attached drawing.
Fig. 2 be one embodiment of the invention engine and braking resistor shared cooling system structure diagram.Please
With reference to figure 2, the shared cooling system of a kind of engine and braking resistor, including radiator and cooling fan.Wherein, engine
After water channel of the coolant followed by radiator, the cooling duct of braking resistor and engine, radiator is flowed to.
In one embodiment of the invention, when vehicle is in damped condition, braking resistor does not work substantially, radiator
It is used to cool down braking resistor with cooling fan；When vehicle is in driven driving cycle, engine output
Smaller or be zero, radiator and cooling fan utilize engine output and braking for being cooled down to engine
Resistance consumption power can make them share a set of cooling systems alternateed in operating mode the characteristics of.
In one embodiment of the invention, down hill braking operating mode and filling full of energy-storage system when vehicle are in vehicle
Man Hou using motor regenerative braking, is also turned on the braking resistor to consume braking power.
Specifically, when vehicle is in braking or lower long slope is braked, engine is often not required to export again in itself very big
Power, engine be often operated in idling operation or it is clear-cut shut down, at this moment the cooling of engine and cooling system often have
Larger margin of operation can be used for cooling down the fever of braking resistor；For the engine of 100kW output powers, cooling system
The cooling capacity of system is often also in more than 100kW；That is the cooling system of the engine of 100kW can take away braking resistor
The continuous braking feedback power of 100kW, cools down it.
When vehicle, which is in emergency braking and lower long slope, to be braked, the power of motor braking feedback it is often bigger, it is necessary to
Dissipate larger feedback braking power (50~100kW even more highs) in the braking resistor short time, to the cooling system of braking resistor
The cooling capacity of system is also higher, but the usually non-brake operating mode of other major parts, and braking resistor work is not required, and is it
It is often uneconomical that a powerful cooling system is separately configured；And the peak power of braking process and continuing for lower long slope
Braking power can be enough to take away its generation using the cooling system of engine in the even greater ranges of 50~100kW
Heat.
It is by the advantages of engine of the embodiment of the present invention and shared cooling system of braking resistor：Work as heavy vehicle
When needing to brake for a long time in lower long slope, it can charge first preferentially using motor regenerative braking to energy-storage system, recycling braking
Energy；It after being full of full of energy-storage system, continues to using motor regenerative braking, is also turned on braking resistor, consumption braking
Power；Due to the powerful cooling capacity of engine-cooling system, braking resistor can long-time power consumption braking power,
It is exactly that vehicle can use motor regenerative braking for a long time, so as to avoid mechanical (frictional disk or friction drum) braking system too early
Work, reduce the abrasion of mechanical braking system, improve vehicle, especially heavy vehicle braking system security and
Reliability.
In one embodiment of the invention, semiconductor switch device is used by pulsewidth modulation to control the braking electricity
Hinder the mean power of consumption.
Specifically, in Fig. 2 control braking resistor whether the device for power switching connected with power bus, can be relay
Or the power device of semiconductor, such as IGBT.If using IGBT, the pulsewidth modulation (PWM) of certain frequency can also be passed through
Control signal, to control the mean power that braking resistor consumes.I.e. by adjusting the duty cycle of the PWM waveform of K is switched, to control
The average consumed power value of braking resistor, make its feedback braking power and (energy-storage system+accessory system) with motor can be with
The power of absorption matches.
It is compared with the air-cooled braking resistor of transmission, can have bigger using the braking resistor that cooling system is shared with engine
Braking energy dissipation capacity, range of temperature is more steady, can the short time absorb bigger peak value braking power, so as to
For protection energy-storage system and the stabilization of bus voltage is maintained to provide more convenient condition.More have in terms of cost and reliability excellent
Gesture.
Requirement in Fig. 2 to braking resistor is, it is desirable that braking resistor must can be with long-term work in engine operating temperature
In the range of, i.e., braking resistor can the long-term work under the conditions of 85~100 DEG C.
In one embodiment of the invention, start in the environment temperature residing for vehicle less than in the case of preset temperature
During engine, discharge from the braking resistor in energy-storage system.
It specifically, under cryogenic, can be from energy-storage system (such as power electric when engine needs warming-up to start
Pond) in discharge braking resistor, at this moment because engine-cooling system can be braked resistance and quickly heat, can accelerate to start
The cooling water temperature-rise period of machine, the warming-up process after shortening cold post-start time and starting.
In addition, other compositions of the shared cooling system of the engine and braking resistor of the embodiment of the present invention and effect pair
All it is known for those skilled in the art, in order to reduce redundancy, does not repeat.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show
