Detailed Description
The embodiment of the application solves the technical problem that the mixed motor vehicle is still in an anchoring state after fuel oil is supplemented if the SOC is too low under the condition that the mixed motor vehicle does not have fuel oil in the prior art by providing the mixed motor vehicle control method.
The technical scheme of the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
a control method of a hybrid electric vehicle comprises the following steps: monitoring the residual battery capacity of a power battery of the hybrid electric vehicle; when the residual electric quantity of the battery is in a first set electric quantity range, monitoring oil level data in an oil tank of the hybrid electric vehicle; and when the oil level data is smaller than a preset threshold value, if the upper high pressure instruction is received, refusing to respond to the upper high pressure instruction.
According to the embodiment, under the oil shortage state of the hybrid electric vehicle, the power battery can be used as energy source for outputting, the hybrid electric vehicle is driven to run, after oil shortage occurs and the residual electric quantity of the battery is reduced to a certain threshold value, in order to avoid that the hybrid electric vehicle still cannot be started again after oiling, an active anchoring mode is adopted, namely the power battery of the hybrid electric vehicle is refused to be high-voltage again, after the hybrid electric vehicle is treated, the hybrid electric vehicle can be normally high-voltage again after oiling again, and maintenance of professional maintenance staff is not needed, so that user experience is improved.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.
First, the term "and/or" appearing herein is merely an association relationship describing associated objects, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The hybrid motor vehicle type has the characteristics of energy conservation, low emission and the like, and becomes the key point of automobile research and development. Hybrid vehicles typically have two sources of energy: power cells and fuel engines. However, for the hybrid motor vehicle type, when the condition that the oil is lacking and the power cannot be provided by the engine occurs, the hybrid motor vehicle is driven by the power battery, the power battery can continuously consume power, the state that the power is limited and the power is low is gradually generated, and even the condition that the vehicle is still anchored after the hybrid motor vehicle is oiled 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 controller of a hybrid vehicle, and includes steps S11-S17.
Step S11, monitoring the residual battery capacity of the power battery of the hybrid electric vehicle, and grading the residual battery capacity according to the current residual battery capacity.
In this embodiment, the remaining battery power is divided into a plurality of set power ranges (the value ranges of the set power ranges are different), which specifically includes:
fourth setting electric quantity range: a fourth power threshold S4 or more (corresponding to step S12);
third setting electric quantity range: a third power threshold S3 or more and a fourth power threshold S4 or less (corresponding to step S13);
second set electric quantity range: greater than or equal to the second electrical quantity threshold S2 and less than the third electrical quantity threshold S3 (corresponding to step S14);
first setting electric quantity range: a first power threshold S1 or more and a second power threshold S2 or less (corresponding to step S15);
fifth setting electric quantity range: a fifth power threshold S5 or more and a first power threshold S1 or less (corresponding to step S16);
sixth setting electric quantity range: less than a fifth charge threshold S5 (corresponding to step S17).
The respective set power ranges are not coincident, for example, the magnitude relationship between the respective power thresholds is: s4 is more than S3 and less than S2 and less than S1 and less than 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, which may be determined by reasonably setting related influencing parameters according to the assembly architecture characteristics of the hybrid electric vehicle (such as HEV or PHEV assembly architecture, where HEV refers to Hybrid Electric Vehicle, hybrid electric vehicle, PHEV refers to Plug-in Hybrid Electric Vehicle, plug-in hybrid electric vehicle), power battery capacity, battery discharge characteristics, battery self-protection threshold value, and the like. For example, for a certain HEV small capacity battery model, the respective charge thresholds may be: s4=30%, s3=28%, s2=25%, s1=22%, s5=20%.
Meanwhile, the determination needs to be carried out according to the environment temperature of the hybrid electric vehicle and the relation between the environment temperature and the discharging efficiency of the power battery. Specifically, for example, when the hybrid vehicle is in a low-temperature environment, the discharging speed of the power battery is faster, so that the above power thresholds can be determined according to the environment temperature of the hybrid vehicle and the relationship between the environment temperature and the discharging efficiency of the power battery, and then each set power range can be determined.
The present embodiment now describes the following steps based on the above-described respective sections:
step S12, when the residual electric quantity of the battery is in a fourth set electric quantity range (namely, the residual electric quantity of the battery is more than or equal to a fourth electric quantity threshold S4), monitoring oil level data in an oil tank of the hybrid electric vehicle; and if the oil level data is smaller than the preset threshold value, controlling the hybrid electric vehicle to run in the pure electric mode.
When the remaining battery power is equal to or greater than the fourth power threshold S4, it means that the power is sufficient. And monitoring oil level data of the hybrid electric vehicle, wherein if the oil level data is smaller than a preset threshold value, the hybrid electric vehicle is in an oil shortage state, and the hybrid electric vehicle can run in a pure electric mode at the moment, namely all energy sources of the vehicle come from a power battery.
And S13, when the residual electric quantity of the battery is in a third set electric quantity range (namely, the residual electric quantity is larger than or equal to a third electric quantity threshold S3 and smaller than a fourth electric quantity threshold S4), executing at least one of sending out the vehicle performance limited prompt information, lighting a turtle lamp of the hybrid vehicle and controlling the hybrid vehicle to enter a limp-home vehicle speed mode.
As the running time of the hybrid vehicle in the electric-only mode increases, the electric quantity of the power battery gradually decreases from a state of being greater than or equal to the fourth electric quantity threshold value S4 to a state of being less than the fourth electric quantity threshold value S4.
When the remaining battery power is greater than or equal to the third power threshold S3 and less than the fourth power threshold S4, the power of the power battery is insufficient at this time, so that in order to prolong the driving range, the whole vehicle can reduce some unnecessary power loss, such as turning off the electric air conditioner, and high-voltage loads such as PTC (Positive Temperature Coefficient, electric heater). At the moment, the vehicle performance limitation prompting information can be sent out to remind a driver of electric quantity change. The tortoise lamp of the electric quantity hybrid electric vehicle can remind a driver to run at a low speed. Of course, the limp-home vehicle speed mode may be performed to further reduce the power loss rate.
Step S14, when the remaining battery power is within the second set power range (i.e. greater than or equal to the second power threshold S2 and less than the third power threshold S3), monitoring whether the power battery is in an uncharged state; if the power battery is in an uncharged state, the power battery is controlled to disconnect high-voltage output; after the power battery is controlled to disconnect the high voltage output, when an upper high voltage command is received, the upper high voltage command is responded, and the upper high voltage of the power battery is controlled.
As the power consumption time of the hybrid vehicle increases, the electric quantity of the power battery gradually decreases from a state of being greater than or equal to the third electric quantity threshold value S3 to a state of being less than the third electric quantity threshold value S3.
When the remaining battery power is greater than or equal to the second power threshold S2 and less than the third power threshold S3, whether the power battery starts to charge is monitored, if the power battery is not in a charging state, the power battery is controlled to disconnect high-voltage output, and a driver is forced to be reminded of charging or oiling.
However, in this case, the hybrid vehicle can actually run, so as to further extend the driving range, the driver may repeatedly go up the high voltage, that is, after the vehicle controller controls the power battery to disconnect the high voltage output, when receiving the high voltage command, the vehicle controller still responds to the high voltage command and controls the high voltage on the power battery, so that the hybrid vehicle may continue to run for a certain distance, and move the vehicle forward to the roadside safety area.
Step S15, when the residual electric quantity of the battery is in a first set electric quantity range (namely, the residual electric quantity is larger than or equal to a first electric quantity threshold value S1 and smaller than a second electric quantity threshold value S2), oil level data in an oil tank of the hybrid electric vehicle are monitored; and when the oil level data is smaller than a preset threshold value, if the upper high pressure instruction is received, refusing to respond to the upper high pressure instruction.
As the power consumption time of the hybrid vehicle increases, the electric quantity of the power battery gradually decreases from a state of being greater than or equal to the second electric quantity threshold value S2 to a state of being less than the second electric quantity threshold value S2.
When the remaining battery power is greater than or equal to the first power threshold S1 and less than the second power threshold S2, if the fuel tank of the hybrid vehicle is in a fuel-starved state, then if power consumption is continued again, it is likely that the vehicle cannot be pressurized even if the hybrid vehicle is replenished with fuel. When this occurs, maintenance is only performed.
In order to avoid such a situation, when the remaining battery power is greater than or equal to the first power threshold S1 and less than the second power threshold S2 and the fuel tank of the hybrid vehicle is in a fuel-starved state, when the upper high voltage command is received, the response to the upper high voltage command is refused, so that the power battery can be prevented from continuously consuming power.
In summary, in this embodiment, in the fuel-starved state of the hybrid electric vehicle, the power battery may be used as the energy source to output, so as to drive the hybrid electric vehicle to run, after the fuel-starved state occurs and the residual battery power decreases to a certain threshold value, in order to avoid that the hybrid electric vehicle still cannot be restarted after refueling, an active anchoring manner is adopted, that is, the power battery of the hybrid electric vehicle is refused to be pressurized again, so after the treatment, after refueling the hybrid electric vehicle again, the hybrid electric vehicle can be pressurized again normally, without maintenance of professional maintenance personnel, so as to improve user experience.
The steps S11-S15 are mainly used for the process of oil shortage in the oil tank and gradual reduction of the electric quantity of the power battery, and when the hybrid electric vehicle actually runs, the situation that the oil tank is not short of oil, the engine cannot be charged due to failure, and the electric quantity of the power battery is gradually reduced due to long-time maintenance and investigation is mainly adopted for processing in steps S16 and S17.
In step S16, when the remaining battery power is within the fifth set 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 oil tank of the hybrid vehicle is greater than or equal to the preset threshold, and when the upper high voltage command is received, the response to the upper high voltage command is refused.
When the remaining battery power is greater than or equal to the fifth power threshold S5 and less than the first power threshold S1, it means that the power of the power battery is already low, and the oil level data of the oil tank is greater than or equal to the preset threshold at this time, which means that the hybrid vehicle is not starved of oil. At the moment, when the upper high voltage command is received, the response of the upper high voltage command is refused, the SOC is prevented from falling to the lower limit of the broken high voltage of the battery management system, and further the power control protection of the whole vehicle and the hardware protection of the battery are realized, so that more serious faults are avoided.
And step S17, when the residual electric quantity of the battery is in the sixth set electric quantity range (namely, is smaller than the fifth electric quantity threshold S5), determining that the battery management system of the hybrid electric vehicle is in fault, and controlling the power battery to disconnect high-voltage output.
When the remaining battery power is less than the fifth power threshold S5, it means that the battery management system has a three-level fault irrespective of the shortage of the oil in the oil tank, at which time the high voltage output needs to be disconnected, and the fault can be removed only by a professional serviceman using a diagnostic tool.
In summary, in this embodiment, in the fuel-starved state of the hybrid electric vehicle, the power battery may be used as the energy source to output, so as to drive the hybrid electric vehicle to run, after the fuel-starved state occurs and the residual battery power decreases to a certain threshold value, in order to avoid that the hybrid electric vehicle still cannot be restarted after refueling, an active anchoring manner is adopted, that is, the power battery of the hybrid electric vehicle is refused to be pressurized again, so after the treatment, after refueling the hybrid electric vehicle again, the hybrid electric vehicle can be pressurized again normally, without maintenance of professional maintenance personnel, so as to improve user experience.
