[0016] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Figure 1 The method for handling low-liquid-level fuel in a vehicle disclosed in the present invention is shown. In an embodiment of the present invention, for a hybrid vehicle, the method includes: determining whether the driving mode is an engine driving mode or a motor driving mode according to the magnitude relationship between the current fuel level of the vehicle and the fuel exhaustion position, determining whether to perform braking energy recovery, whether to perform coasting energy recovery, and determining the components enabled by the high-voltage electricity of the vehicle.

[0019] In some optional implementations of any embodiment of the present disclosure, the driving mode is determined to be the engine driving mode or the motor driving mode based on the size relationship between the current fuel level of the vehicle and the fuel exhaustion position, including: if the current fuel level of the vehicle is between the warning position and the fuel exhaustion position, then the engine driving mode is adopted.

[0020] The warning position refers to the fuel level position when the fuel level is very low. The fuel exhaustion position means that once the fuel level is less than or equal to this position, the engine cannot be driven.

[0021] Optionally, in this implementation, it may be determined to perform the braking energy recovery and not to perform the coasting energy recovery.

[0022] Optionally, the high voltage electricity of the vehicle is determined to enable a DC to DC converter DCDC and an electric power steering system EPS.

[0023] In some optional implementations of any embodiment of the present disclosure, the driving mode is determined to be the engine driving mode or the motor driving mode based on the size relationship between the current fuel level of the vehicle and the fuel exhaustion position, including: if the current fuel level of the vehicle is less than or equal to the fuel exhaustion position, then the driving mode is determined to be the engine driving mode or the motor driving mode based on the size relationship between the state of charge SOC of the vehicle and the charge exhaustion threshold.

[0024] Optionally, the driving mode is determined to be the engine driving mode or the motor driving mode based on the size relationship between the vehicle's state of charge SOC and a power depletion threshold, including: if the vehicle's state of charge SOC is greater than or equal to the power depletion threshold, then the motor driving mode is adopted.

[0025] Optionally, the determining whether to perform braking energy recovery and whether to perform coasting energy recovery includes: determining to perform the braking energy recovery and not to perform the coasting energy recovery.

[0026] Optionally, the determining to perform the braking energy recovery includes: if the battery state of the vehicle is less than a fully charged state, performing the braking energy recovery at maximum capacity.

[0027] Optionally, determining the components enabled by the high voltage electricity of the vehicle includes: determining that the high voltage electricity of the vehicle enables a direct current to direct current converter DCDC and an electric power steering system EPS.

[0028] The present disclosure provides another method for treating low-liquid-level fuel in a vehicle according to an embodiment of the present disclosure. The method for treating low-liquid-level fuel in a vehicle comprises:

[0029] When the value of the fuel level r is rFuel1 (fuel exhaustion position) < r≤ rFuel2 (warning position), the vehicle enters the "fuel saving, power saving and power storage" mode. At this time, the motor is prohibited from participating in the drive, and the vehicle does not generate electricity but may recover energy. To ensure the endurance, only braking energy recovery is allowed (as long as SOC < 100%, braking energy recovery should be performed at the maximum capacity), and sliding energy recovery is not allowed (considering the loss of kinetic energy to electrical energy and then to energy, that is, all energy is used for driving as much as possible, that is, the energy used for driving is greater than the energy threshold). The high-voltage components only allow DCDC and EPS to be enabled, and the non-essential components including air conditioning and heating are disconnected. The engine torque is driven along the economy curve.

[0030] When the fuel level r≤rFuel1, that is, the fuel level is close to 0, the following is done based on the battery SOC:

[0031] If SOC>rSOC (power depletion threshold), that is, the power is sufficient, the "power saving and fuel prohibition" mode is entered. At this time, the clutch is disengaged, the engine is prohibited from driving, and only braking energy recovery is allowed (as long as SOC<100%, braking energy recovery should be carried out at the maximum capacity), and sliding energy recovery is not allowed (considering the loss of kinetic energy to electrical energy and then to energy, that is, all energy is used for driving as much as possible), and only DCDC and EPS are allowed to be enabled for high-voltage components, and non-essential components including air conditioning and heating are disconnected.

[0032] If SOC≤rSOC, the battery power is almost exhausted and the vehicle is prohibited from driving.

[0033] When the fuel level is low, the car will not generate electricity while driving, and all the remaining fuel will be used for driving. The car will enter power saving mode, and the motor will not participate in driving. High voltage electricity will only be used for auxiliary machines necessary for driving, such as DCDC and EPS. Non-essential components such as air conditioning and heating are prohibited from running, in preparation for pure electric driving when the fuel level drops to 0.

[0034] When the fuel level is close to 0, the engine cannot be driven at all and can only be driven by pure electricity. At this time, the power saving mode should be entered to use as much power as possible for driving. The high-voltage components only allow DCDC and EPS to be enabled, and disconnect the air conditioner, heater, etc. The above operations can be performed by the HCU.
