POWER CONTROL METHOD AND TERMINAL DEVICE FOR HYDRAULIC HYBRID VEHICLE, AND STORAGE MEDIUM
20230286511 · 2023-09-14 ·

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.

Control device and method for starting a combustion engine during free-wheeling a vehicle with such device, computer program for executing the method and computer readable medium containing the program

A method, performed by a control device, for starting a combustion engine during free-wheeling with engine off is described. The method comprises a step of controlling the clutch to a partially closed state, thereby starting the combustion engine; a step of controlling the clutch to an open state when the combustion engine has started, but prior to the output shaft of the combustion engine has reached a rotational speed synchronized with the rotational speed of the input shaft of the gearbox; and a step of synchronizing the speed of the combustion engine to the speed of the input shaft of the gearbox through control of fuel injection to the combustion engine.

DRIVING SUPPORT DEVICE

The posture of the driver is detected from the driver head portion, and the detected value and the driver mounting determination value are used to determine that the driver is pushing the vehicle and obtain the vehicle pushing command value. Converts the vehicle pushing command value to the target vehicle pushing assistance vesicle speed, determines whether vehicle pushing assistance can be performed based on the driver's posture and the vehicle condition, and outputs the vehicle pushing assistance permission determination. Then, from the target vehicle pushing assistance vehicle speed and the vehicle pushing assistance permission determination, the control amount for the vehicle power source that assists the vehicle pushing is calculated and output.
