In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Hybrid vehicles are the key point for automobile research and development due to the characteristics of energy conservation, low emission and the like. Hybrid vehicles typically have two energy sources: power battery and fuel engine. However, for a hybrid vehicle type, when the engine is in an oil shortage state and cannot provide power, the hybrid vehicle is driven by the power battery, the power battery can continuously consume power, the states of limited power and high voltage gradually occur, and even the situation that the vehicle is still anchored after the hybrid vehicle is refueled due to the fact that the SOC is too low can occur.
The embodiment provides a hybrid vehicle control method as shown in fig. 1, which can be applied to a vehicle control unit of a hybrid vehicle, and the method includes steps S11-S17.
And step S11, monitoring the battery residual capacity of the power battery of the hybrid vehicle, and performing grading processing according to the current battery residual capacity.
In this embodiment, the remaining battery power is divided into a plurality of setting power ranges (the value ranges of the setting power ranges are different), and the method specifically includes:
the fourth setting electric quantity range: greater than or equal to the fourth threshold of electric quantity S4 (corresponding to step S12);
the third setting electric quantity range: greater than or equal to the third power threshold S3 and less than the fourth power threshold S4 (corresponding to step S13);
the second set electric quantity range: greater than or equal to the second power threshold S2 and less than the third power threshold S3 (corresponding to step S14);
the first set electric quantity range: greater than or equal to the first power threshold S1 and less than the second power threshold S2 (corresponding to step S15);
the fifth setting electric quantity range: greater than or equal to the fifth power threshold S5 and less than the first power threshold S1 (corresponding to step S16);
sixth setting electric quantity range: less than the fifth power threshold S5 (corresponding to step S17).
The respective setting electric quantity ranges are not coincident, for example, the magnitude relation between the respective electric quantity thresholds is: s4 < S3 < S2 < S1 < S5.
The end values of the above-mentioned set Electric quantity ranges specifically include a first Electric quantity threshold value S1, a second Electric quantity threshold value S2, a third Electric quantity threshold value S3, a fourth Electric quantity threshold value S4, and a fifth Electric quantity threshold value S5, and can be reasonably set and determined according to the assembly structure characteristics of the Hybrid Vehicle (such as an HEV or a PHEV assembly structure, wherein the HEV refers to a Hybrid Electric Vehicle, and the PHEV refers to a Plug-in Hybrid Electric Vehicle, and a Plug-in Hybrid Electric Vehicle), the power battery capacity, the battery discharge characteristic, the battery self-protection threshold value, and other relevant influence parameters. For example, for a certain HEV small-capacity battery model, the respective charge thresholds may be: 30% for S4, 28% for S3, 25% for S2, 22% for S1 and 20% for S5.
Meanwhile, the determination is also needed according to the ambient temperature of the hybrid vehicle and the relationship between the ambient temperature and the discharge efficiency of the power battery. Specifically, when the hybrid vehicle is in a low-temperature environment, the discharge speed of the power battery is faster, so that each electric quantity threshold value can be determined according to the environment temperature of the hybrid vehicle and the relationship between the environment temperature and the discharge efficiency of the power battery, and each set electric quantity range can be further determined.
The present embodiment now describes the steps based on the above sections as follows:
step S12, monitoring oil level data in the oil tank of the hybrid vehicle when the remaining battery capacity is in a fourth set electric quantity range (namely, greater than or equal to a fourth electric quantity threshold value S4); and if the oil level data is smaller than the preset threshold value, controlling the hybrid vehicle to run in the pure electric mode.
When the battery remaining capacity is equal to or greater than the fourth capacity threshold S4, it means that the capacity is sufficient. Monitoring the oil level data of the hybrid vehicle, wherein if the oil level data is smaller than a preset threshold value, the hybrid vehicle is in an oil shortage state, and the hybrid vehicle can run in a pure electric mode at the moment, namely all energy of the vehicle comes from a power battery.
And step S13, when the residual battery capacity is in a third set capacity range (namely, greater than or equal to the third capacity threshold S3 and less than the fourth capacity threshold S4), at least one step of sending out a finished vehicle performance limitation prompting message, lighting a turtle lamp of the hybrid vehicle and controlling the hybrid vehicle to enter a limp vehicle speed mode is executed.
As the hybrid vehicle travels in the electric-only mode for an increased period of time, the charge level of the power battery is gradually decreased from a state equal to or greater than the fourth charge threshold value S4 to a state less than the fourth charge threshold value S4.
When the remaining battery capacity is greater than or equal to the third capacity threshold S3 and less than the fourth capacity threshold S4, the capacity of the power battery is insufficient, and in order to extend the driving range, the entire vehicle may reduce some unnecessary capacity loss, such as turning off the electric air conditioner, and turning off the PTC (Positive Temperature Coefficient, electric heater) and other high-voltage loads. At the moment, prompt information that the performance of the whole vehicle is limited can be sent to remind a driver of the change of the electric quantity. The turtle lamp of the electric hybrid vehicle can remind the driver of driving at a low speed. Of course, the limp home speed mode may be performed to further reduce the power loss rate.
Step S14, when the remaining battery capacity is in a second predetermined capacity range (i.e. greater than or equal to the second capacity threshold S2 and less than the third capacity threshold S3), monitoring whether the power battery is in an uncharged state; if the power battery is in an uncharged state, controlling the power battery to disconnect the high-voltage output; and after the power battery is controlled to disconnect the high-voltage output, responding to the high-voltage command and controlling the high voltage on the power battery when the high-voltage command is received.
With the increase of the electricity consumption time of the hybrid vehicle, the electric quantity of the power battery is gradually reduced from a state of being greater than or equal to the third electric quantity threshold value S3 to a state of being smaller than the third electric quantity threshold value S3.
When the residual electric quantity of the battery is greater than or equal to the second electric quantity threshold value S2 and smaller than the third electric quantity threshold value S3, whether the power battery starts to be charged or not is monitored, if the power battery is not in a charging state, the power battery is controlled to be disconnected from high-voltage output, and a driver is forcibly reminded of needing to charge or refuel.
However, in this case, the hybrid vehicle can actually run, and in order to further extend the driving range, the driver may repeat the high voltage application, that is, the vehicle control unit may still respond to the high voltage application command and control the high voltage application of the power battery when receiving the high voltage application command after controlling the power battery to disconnect the high voltage output, so that the hybrid vehicle may continue to run for a distance to move the vehicle forward to the roadside safety area.
Step S15, monitoring oil level data in a fuel tank of the hybrid vehicle when the remaining battery capacity is in a first set power range (namely, greater than or equal to a first power threshold S1 and less than a second power threshold S2); and when the oil level data is smaller than the preset threshold value, if an upper high pressure instruction is received, refusing to respond to the upper high pressure instruction.
With the increase of the electricity consumption time of the hybrid vehicle, the electric quantity of the power battery is gradually reduced from a state of being greater than or equal to the second electric quantity threshold value S2 to a state of being smaller than the second electric quantity threshold value S2.
When the remaining battery capacity is greater than or equal to the first capacity threshold value S1 and less than the second capacity threshold value S2, if the fuel tank of the hybrid vehicle is in a fuel-starved state, if power consumption is continued again, the vehicle may not be able to be supplied with high voltage even if the fuel is replenished in the hybrid vehicle. When this occurs, only maintenance can be performed.
In order to avoid the situation, when the remaining battery capacity is greater than or equal to the first capacity threshold value S1 and less than the second capacity threshold value S2 and the oil tank of the hybrid vehicle is in an oil shortage state, the embodiment refuses to respond to the high voltage command when receiving the high voltage command, and further can avoid the power battery from continuously consuming power.
In summary, in the embodiment, in the oil shortage state of the hybrid vehicle, the power battery can be used as the energy output to drive the hybrid vehicle to run, when the oil shortage occurs and the remaining battery capacity of the battery is reduced to a certain threshold value, in order to avoid that the hybrid vehicle still cannot be restarted after refueling, an active anchoring mode is adopted, that is, the power battery of the hybrid vehicle is refused to be pressurized again, after the treatment, after refueling of the hybrid vehicle is carried out again, the hybrid vehicle can be pressurized again normally without the maintenance of professional maintenance personnel, so that the user experience is improved.
So far, the steps S11 to S15 are mainly used in the process that the oil tank is short of oil and the power battery power is gradually reduced, and when the hybrid vehicle is actually operated, the situation that the oil tank is not short of oil, the engine cannot be operated and charged due to a fault, and the power battery power is gradually reduced due to long-time maintenance and investigation is mainly processed by the steps S16 and S17.
In step S16, when the remaining battery power is within a fifth predetermined power range (i.e., greater than or equal to the fifth power threshold S5 and less than the first power threshold S1), if the oil level data in the fuel tank of the hybrid vehicle is greater than or equal to the predetermined threshold, the response to the high-voltage command is rejected when the high-voltage command is received.
When the remaining battery capacity is greater than or equal to the fifth capacity threshold value S5 and less than the first capacity threshold value S1, it means that the capacity of the power battery is low, and when the oil level data of the oil tank is greater than or equal to the preset threshold value, it means that the hybrid vehicle is not out of oil. At the moment, when a high-voltage instruction is received, the high-voltage instruction is refused to be responded, the SOC is prevented from being reduced to the lower limit of the high-voltage interruption of the battery management system, further, the power control protection of the whole vehicle and the hardware protection of the battery are realized, and more serious faults are avoided.
And step S17, when the residual battery capacity is in the sixth set capacity range (namely, less than the fifth capacity threshold S5), determining that the battery management system of the hybrid vehicle is in failure, and controlling the power battery to disconnect the high-voltage output.
When the remaining battery capacity is less than the fifth capacity threshold value S5, whether the oil tank is out of oil or not, it means that the battery management system has a three-level fault, at which time the high voltage output needs to be disconnected, and the fault can only be removed by a professional serviceman using a diagnostic tool.
In summary, in the embodiment, in the oil shortage state of the hybrid vehicle, the power battery can be used as the energy output to drive the hybrid vehicle to run, when the oil shortage occurs and the remaining battery capacity of the battery is reduced to a certain threshold value, in order to avoid that the hybrid vehicle still cannot be restarted after refueling, an active anchoring mode is adopted, that is, the power battery of the hybrid vehicle is refused to be pressurized again, after the treatment, after refueling of the hybrid vehicle is carried out again, the hybrid vehicle can be pressurized again normally without the maintenance of professional maintenance personnel, so that the user experience is improved.
