In recent years, as the awareness of rising oil prices and energy conservation and carbon reduction has increased year by year, major manufacturers have strengthened the research and development of electric vehicles. In order to save energy for electric vehicles, how to effectively recycle and reuse energy when braking electric vehicles is also an important development goal. .

At present, based on the large-capacity storage characteristics of the battery and the large-rate charge-discharge characteristics of the capacitor, the hybrid vehicle of the battery and the capacitor combination becomes the preferred solution for the electric vehicle fuel-saving system. However, behind the large-capacity charge and discharge of the capacitor, the problem of small capacity is hidden. When the battery is fully charged and the capacitor is used alone, the problem of no electric brake is easily caused in the kinetic energy recovery process of the electric vehicle. There are two main solutions on the market today, one is to reduce in advance. Brake power, the other is to cancel the electric brake after filling the capacitor. The braking process of the first solution is relatively smooth, but because of the small braking power, most of the kinetic energy is lost by the air brake into heat. In the braking process of the second scheme, although the capacitance is already full, it can not absorb all the kinetic energy at high speed, and the electric brake suddenly disappears, which affects the comfort of the brake. In addition, when the conventional electric vehicle is subjected to kinetic energy recovery, it is necessary to consider the battery state back-filling timing and the allowable back-filling condition, so the recycling efficiency is limited.

The amount ΔB and the vehicle speed value correspond to the amount of change ΔV per unit time. Furthermore, the driving behavior determining unit 212 divides the driving behavior into four modes through the results of the above five kinds of determining signals, namely, an acceleration mode, a coasting acceleration mode, a deceleration mode, and a coasting deceleration mode, as shown in Table 1.

The throttle predetermined value A1, the throttle change predetermined value A2, the brake predetermined value C1, the brake change predetermined value C2, and the acceleration predetermined values B1, D1 are all parameters preset by the driving behavior judging unit 212, and the driving behavior judging unit 212 uses these. The parameter is compared with the judgment signal, and the mode corresponding to the driving behavior can be judged and the corresponding taxi time, the starting vehicle speed value, and the ending vehicle speed value are output. Since the judgment manner of the driving behavior judging unit 212 is a conventional technique, it will not be described again.

The magnitude of the reversible kinetic energy E(t) is the reversible kinetic energy value 246.

The control module 220 is electrically connected to the estimation module 210 and the energy storage device 400, and receives the refillable kinetic energy value 246 from the estimation module 210 and the first energy storage recoverable power value 412 from the energy storage device 400, and the second The energy storage recoverable power value is 422.

The memory unit 222 is electrically connected to the control decision unit 224 and stores five actuation context information 252. The control decision unit 224 decides to output one of the action context information 252 to the power splitter 300 according to the refillable kinetic energy value 246, the first stored energy recoverable power value 412, and the second stored energy recoverable power value 422, such that the power splitter 300 is caused. The electrical energy is distributed to the energy storage device 400 and the load device 500 in accordance with one of the actuation context information 252. In detail, the five actuation situation information 252 stored by the memory unit 222 are the first actuation information, the second actuation information, the third actuation information, the fourth actuation information, and the fifth actuation information. In other words, the first actuation information represents that the power distributor 300 simultaneously charges the first energy storage component 410 and the second energy storage component 420, and also represents the distribution of electrical energy to the first energy storage component 410 and the second energy storage component 420; Two actuation information represents power distribution The device 300 only charges the first energy storage component 410, and also represents the power distribution to the first energy storage component 410; the third actuation information represents the power distributor 300 charging the first energy storage component 410 while powering the second load 520.

N stands for non-conformity and Y stands for eligibility. For example, if the condition one is Y, the reversible kinetic energy value 246 is greater than the first energy storage recoverable power value 412; if the condition one is N, the refillable kinetic energy value 246 is less than or equal to the first stored energy retrievable power value. 412.
