Power control method and terminal device for hydraulic hybrid vehicle, and storage medium
The present invention relates to a power control method and terminal device for a hydraulic hybrid vehicle, and a storage medium. The method includes: S1: predicting, according to environmental information of a road ahead, recoverable energy in the road ahead; S2: calculating, according to the predicted recoverable energy, a critical pressure required by a hydraulic accumulator to recover the recoverable energy; and S3: determining whether a current pressure of the hydraulic accumulator is greater than the critical pressure, and if so, reducing fuel output power of an engine and controlling the hydraulic accumulator to release energy such that the current pressure of the hydraulic accumulator is less than or equal to the critical pressure. According to the present invention, when it is predicted that there is a high probability of energy recovery ahead, the energy stored in the hydraulic accumulator is used up in advance, so that the hydraulic accumulator has enough space to recover energy when the energy recovery occurs in future. This can make full use of the characteristic of the hydraulic accumulator of being suitable for frequent storage and release of energy, thereby achieving the economy of energy consumption of the whole vehicle.

AGGREGATION SYSTEM, CONTROL METHOD THEREOF, AND CONTROL APPARATUS
In an aggregation system comprising a control apparatus which is provided for each consumer and a server apparatus, the server apparatus calculates, for each of the consumers and as an allocation amount of the consumer, an upper limit value for the power which the consumer inputs from the system or a lower limit value for the power which the consumer is to output to the system, according to a requested power provision amount, and sends the respective control instructions designating the calculated allocation amount of each consumer to the control apparatus of the consumer, and the control apparatuses each control the charging and discharging of the corresponding power apparatus so that the power input from the system is equal to or smaller than the allocation amount designated in the control instruction or so that power equal to or larger than the allocation amount is output to the system.
Hybrid vehicle
A cruising distance coefficient is set that is smaller than a value of 1 and that becomes smaller as a use index indicating a degree of use of external charging gets smaller, and a cruising distance is calculated by multiplying a fuel quantity by the set cruising distance coefficient and a fuel consumption coefficient. Then, a display cruising distance is calculated by subtracting from the cruising distance a value obtained by subtracting a set-time travel distance Lset, obtained when the cruising distance is calculated, from a travel distance from a travel distance meter, and the calculated display cruising distance is displayed on a display device in front of a driver's seat.
