[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. The described embodiments are only exemplary embodiments of the present application and not all implementation manners. Those skilled in the art can obtain other embodiments without creative efforts in combination with the embodiments of the present application, and these embodiments are also within the protection scope of the present application.
[0051] Taking a hybrid vehicle as an example, when a user uses the remote start function, the remote start function is usually realized by the power battery discharging. However, when the power battery is in a limited state, such as when the power of the power battery is extremely low or in a low-temperature environment, due to the limited discharging ability of the power battery, the user's remote start request will be rejected, affecting the user experience.
[0052] Based on this, an embodiment of the present application provides a remote start method for a hybrid vehicle, so as to still achieve the remote start of the hybrid vehicle when the power battery is restricted. Specifically, when a user wants to remotely start a target load of the hybrid vehicle, the hybrid vehicle can receive a remote start instruction for the target load. Then, based on the remote start instruction for the target load, the power consumption of the target load is determined. For example, the remote start instruction may include a preset operating state of the target load to determine the power consumption of the target load. When the power consumption of the target load is greater than the discharge power of the power battery, it means that the discharge capacity of the power battery at this time cannot meet the power consumption of the target load. At this time, the engine can be controlled to start, and the engine can be controlled to operate based on the power consumption of the target load. Thus, the target load is controlled to operate based on the output power during engine operation. Through the method provided by the present application, when the discharge capacity of the power battery cannot meet the remote start requirement of the hybrid vehicle, the engine can be controlled to operate in advance to meet the power consumption required for remote start, thereby realizing the remote start function of the hybrid vehicle when the power battery is restricted.
[0053] To facilitate understanding of the solution provided by the embodiment of the present application, the following will be specifically introduced in conjunction with the accompanying drawings.
[0054] See Figure 1 , Figure 1 which is a flowchart of a remote start method for a hybrid vehicle provided by an embodiment of the present application.
[0055] This method can be executed by the control device of the hybrid vehicle. For example, the control device can be a vehicle control unit (VCU), which can collect signals, status information, etc. of the hybrid vehicle for analysis and integration to achieve the control function of the hybrid vehicle.
[0056] This method may include the following steps:
[0057] S101: Receive a remote start instruction for the target load.
[0058] When a user wants to remotely start a target load of the hybrid vehicle, a remote start instruction can be sent to the vehicle control unit of the hybrid vehicle through a remote control device.
[0059] In a possible implementation manner, the user can select to control the target load to operate through a start module for the target load in the remote control device. Among them, the remote start instruction may include a preset operating state of the target load, so that the vehicle control unit can control the target load to operate in the preset operating state subsequently.
[0060] For example, the remote control device can be a remote controller, which includes a start button for the target load. And when the user triggers the start button, the user can also select a preset operating state of the target load.
[0061] S102: Determine the power consumption of the target load based on the remote start instruction.
[0062] When the vehicle controller receives a remote start instruction for the target load, it can determine the power consumption that the target load is expected to require.
[0063] Optionally, when the remote start instruction includes a preset operating state of the target load, the power consumption of the target load can be determined according to the preset operating state. In a possible application scenario, the target load can be the air conditioning equipment of a hybrid vehicle. When the user remotely starts the air conditioning equipment, the user can select the temperature that the air conditioning equipment is preset to reach, which is used as the preset operating state of the air conditioning equipment. Then, according to the temperature that the air conditioning equipment is preset to reach, the power consumption required by the air conditioning equipment is determined.
[0064] S103: When the power consumption of the target load is greater than the discharge power of the power battery, control the engine to start and control the engine to operate based on the power consumption of the target load.
[0065] When the power consumption of the target load is greater than the discharge power of the power battery, that is, the power battery cannot meet the power consumption demand of the target load. For example, when the power battery is in a low temperature environment or has a low battery level, the discharge capacity is limited at this time. Among them, the discharge power of the power battery can be determined according to the state of charge of the power battery, the cell temperature, etc. At this time, the vehicle controller can control the engine to start and utilize the characteristic that the hybrid vehicle can be charged in series, that is, by controlling the engine to operate in series to drive the generator to rotate to realize power generation.
[0066] In specific implementation, when starting the engine of a hybrid vehicle, it can be achieved through a starting motor. The vehicle controller can control the power battery to supply power to the starting motor to control the operation of the starting motor. When the starting motor operates, it can convert the electrical energy provided by the power battery into mechanical energy to drive the engine flywheel to rotate to realize the start of the engine.
[0067] Since the power consumption when remotely starting the target load to operate is determined, the power that the engine needs to output can be determined according to the power consumption, so as to control the engine to operate to meet the power consumption.
[0068] S104: Control the operation of the target load based on the output power when the engine is operating.
[0069] After controlling the engine to run, it can drive the generator in series to generate electricity, and the provided electric energy can be used by the target load. That is, the target load can be controlled to operate in a preset operating state according to the power consumption.
[0070] In a possible implementation manner, the engine operation can be controlled in the following way. Based on the power consumption of the target load and the maximum charging power of the power battery, the maximum allowable power generation is determined. That is, when the power output by the engine during operation cannot be completely consumed by the target load, the power battery can be charged, so the maximum allowable charging power of the power battery can be determined in advance. According to the sum of the power consumption of the target load and the maximum charging power, the maximum allowable power generation can be determined.
[0071] Optionally, during the charging process of the power battery, the power battery can also heat itself and consume the heating demand power. Therefore, based on the power consumption of the target load, the maximum charging power of the power battery, and the heating demand power of the power battery, the maximum allowable power generation can be determined.
[0072] Then, based on the maximum allowable power generation, the first output power of the engine is determined. Optionally, the engine actually drives the generator to operate for power supply, so the second output power of the generator can be determined first based on the maximum allowable power generation, and then the first output power of the engine can be determined based on the second output power and the preset efficiency. Among them, the preset efficiency represents the ratio between the output power of the engine and the output power of the generator. That is, there must be losses in the power output after the engine drives the generator to operate at a certain output power, and the preset efficiency can represent the conversion efficiency between the output power of the engine and the output power of the generator. For details, please refer to Figure 2 As shown, it is a schematic diagram of power distribution of a hybrid vehicle provided by an embodiment of the present application. The engine drives the generator to operate at the first output power, and the generator outputs the second output power, which can meet the power consumption of the target load, the charging power of the power battery, and the heating demand power of the power battery.
[0073] Based on the specific fuel consumption information of the engine, the target operating point of the engine is determined. Among them, the specific fuel consumption information can be determined in advance. For example, the specific fuel consumption information can be expressed as a BFSC graph. BFSC refers to Brake Specific Fuel Consumption, which represents the mass of fuel consumed by the engine per hour when generating 1 kw of effective power. The smaller the BFSC, the higher the working efficiency of the engine. When the engine speed and output torque are used as the X-axis and Y-axis respectively, and then the specific fuel consumption of the entire engine operating range is tested at a certain interval step size, the BSFC graph can be obtained. Then, according to the output torque and speed, the corresponding output power of the engine can be determined.
[0074] That is, the specific fuel consumption information of the engine may include the correlation among the output power, rotational speed, and specific fuel consumption of the engine. The specific fuel consumption corresponding to the target operating point of the engine is the smallest, that is, the engine is in the optimal efficiency operating state. The target operating point corresponds to a target rotational speed, a target output power, and a target output torque.
[0075] Then, the operation of the engine can be controlled based on the relationship between the first output power and the target output power determined above. In specific implementation, it is judged whether the first output power is greater than or equal to the target output power. If so, the engine is controlled to operate at the target rotational speed and the target output torque. That is, at this time, the engine can be controlled to operate in the optimal efficiency state. At this time, when the first output power of the engine meets the power consumption of the target load and the heating demand power of the power battery, the remaining power can be supplied to the power battery to realize the charging of the power battery.
[0076] If the first output power is less than the target output power, the target rotational speed can be adjusted to the actual rotational speed based on the first output power, and the target output torque can be adjusted to the actual output torque, and the engine is controlled to operate at the actual rotational speed and the actual output torque. That is, when the first output power is less than the target output power, it is necessary to reduce the output torque of the engine, or reduce the rotational speed of the engine, or reduce both the output torque and the rotational speed of the engine, so that the first output power of the engine is less than the target output power. That is, the actual rotational speed is less than or equal to the target rotational speed, and the actual output torque is less than or equal to the target output torque.
[0077] Specifically, when only reducing the rotational speed of the engine, the actual output torque of the engine can be controlled to be the target output torque, and then based on the first output power and the target output torque, the actual rotational speed of the engine is determined. Thus, the engine is controlled to operate at the target output torque and the reduced actual rotational speed to output the first output power. Or, when only reducing the output torque of the engine, the actual rotational speed of the engine can be controlled to be the target rotational speed, and then based on the first output power and the target rotational speed, the actual output torque of the engine is determined. Thus, the engine is controlled to operate at the target rotational speed and the reduced actual output torque to output the first output power. Or, the target rotational speed and the target output torque can be reduced simultaneously so that the reduced actual rotational speed and the actual output torque obtain the first output power.
[0078] Through the method provided by this application, when the discharge capacity of the power battery cannot meet the remote start requirement of the hybrid vehicle, the operation of the engine can be controlled in advance to meet the power consumption required for remote start, so as to realize the remote start function of the hybrid vehicle when the power battery is limited.
[0079] Based on the above method embodiments, an embodiment of the present application further provides a remote start method for a hybrid vehicle.
[0080] The method may include the following steps:
[0081] A1: Receive a remote start instruction for a target load;
[0082] A2: Determine the power consumption of the target load based on the remote start instruction;
[0083] A3: Determine whether the discharge power of the power battery is greater than or equal to the power consumption of the target load; if so, execute step A4 and jump to execute step A9; otherwise, jump to execute step A5;
[0084] A4: Control the power battery to discharge to meet the power consumption of the target load;
[0085] A5: Control the engine to start;
