Description
Technical field
The present invention relates to Control of Electric Vehicles technical fields.
Background technique
In recent years, pure electric automobile achieves the hair more advanced by leaps and bounds under national, local policy encouragement and support
Exhibition, the items technology such as battery system, electric system and full-vehicle control of pure electric automobile achieve significant progress！
In automobile industry, the technological progress and development of pure electric automobile solves component environment and energy problem, still
There are still certain skill upgrading spaces.It is limited by the restriction of the development such as battery, motor and control technology, pure electric automobile
Energy expenditure rate be constantly in higher level.In this case, certain battery capacity, under certain condition as far as possible
Increase the continual mileage of pure electric automobile, reduction vehicle energy expenditure rate becomes pure electric automobile enterprise and constantly visits as far as possible
The direction of rope.In addition for motor-driven manual automobile, due to the architectural difference between motor and engine, in gear shift
Motor speed change is slow compared to engine speed variation；So gear shift under the same conditions, motor-driven manual vapour
Vehicle becomes apparent from than engine-driven manual automobile pause and transition in rhythm or melody sense, pause and transition in rhythm or melody duration is longer.
Currently, vehicle factor is to achieve the purpose that recycle braking energy, the recovery method of permanent torque can be generally taken, commonly
Method is to be recycled in two stages, i.e. coast period and brake operation stage, however this method can not be applicable in completely
In every kind of operating condition.Especially in motor-driven manual running car gearshift procedure, since the revolving speed of motor can not become rapidly
Change, causes motor speed after gear shift to mismatch with the speed under new speed ratio, just will appear apparent pause and transition in rhythm or melody sense, and at this
Along with the loss of kinetic energy during frustrating.
Therefore, the control method for inventing a kind of electric car energy regenerating in gear shift, makes electric car in energy regenerating
Rate is slightly promoted in original basis, while can improve pause and transition in rhythm or melody sense of the automobile in gearshift procedure again, to promotion pure electric automobile
Popularization is of great significance with development.
Summary of the invention
The energy recovery control method when present invention will realize a kind of electromobile gear shift can reduce gearshift procedure
While generating pause and transition in rhythm or melody sense, and vehicle energy expenditure rate can be reduced.
To achieve the goals above, the technical solution adopted by the present invention are as follows: when a kind of manual car gear shifting of motor driven
Energy recovery control method:
When meeting following gear shift energy receipt part simultaneously:
1) accelerator pedal is not trampled；
2) clutch pedal is trampled；
3) current gear is neutral gear；
4) current vehicle speed is greater than 0；
Then power motor is that generator output torque generates electricity, into gear shift energy recuperation mode；
When there is one to be unsatisfactory in gear shift energy receipt part, gear shift energy recuperation mode is exited.
When into gear shift energy recuperation mode, generator torque is different according to gear locating before gear shift and difference.
If gear is in 1 grade before gear shift, shift energy regenerating torque is a, if gear is in 2 grades before gear shift, shift
Energy regenerating torque is b, if gear is in 3 grades before gear shift, gear shift energy regenerating torque is c, if gear is in 4 grades before gear shift
When, gear shift energy regenerating torque is d ..., and so on, each speed shift energy regenerating torque absolute value size relation is a > b
> c > d > ....
Gear shift energy regenerating torque maximum preset upper limit.
Absolute value takes small compared with each speed shift energy regenerating loads the maximum moment under torque revolving speed corresponding with motor, defeated
Torque is loaded out for gear shift energy regenerating.
A kind of automobile, the automobile are manual automobile, and the automobile has energy recycling system, the energy regenerating system
Energy recovery control method carries out energy regenerating when system uses the gear shift in automobile gear shift.
The automobile is pure electric automobile.
The present invention has the advantages that different energy regenerating torques is arranged in the different stalls according to locating for gear shift vehicle in front,
It is as much as possible to recover energy while optimizing different stalls gear shift pause and transition in rhythm or melody sense, and motor maximum load-carrying capacity can be protected,
Gear shift energy regenerating torque maximum is restricted.
Detailed description of the invention
The content of width attached drawing every in description of the invention expression is briefly described below:
The flow chart of energy recovery control method when Fig. 1 is electromobile gear shift.
Specific embodiment
Energy recovery control method when gear shift as shown in Figure 1, specifically includes the following steps:
(1) following 4 conditions need to be met simultaneously by entering gear shift energy regenerating: speed > 0km/h, gear have been in empty
Shelves, completely relieving accelerator pedal, clutch pedal are stepped on, and then enter gear shift energy regenerating when this 4 conditions meet simultaneously.
(2) generator (gear shift energy regenerating motor) torque, the difference according to gear difference locating before gear shift；Such as gear shift
When preceding gear is in 1 grade, shift energy regenerating torque is a, and shift energy regenerating torque is b at 2 grades, gear shift energy time at 3 grades
Receipts torque is c, and gear shift energy regenerating torque is d ... at 4 grades, and so on, each speed shift energy regenerating torque absolute value is big
Small relationship be a > b > c > d > ....
(3) it is protection motor maximum load-carrying capacity, gear shift energy regenerating torque maximum is restricted；Each speed shift energy
Absolute value takes small compared with maximum moment under amount recycling load torque revolving speed corresponding with motor, exports as the load of gear shift energy regenerating
Torque.
Entire car controller monitors the gear shift movement of vehicle in the process of moving, and the energy different according to gear selection in real time
Recycle torque, so improve pause and transition in rhythm or melody sense of the automobile in gearshift procedure, at the same it is as much as possible recover energy, reduce vehicle energy
Consumption rate is measured, thus extending driving range.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
