Description

[0001] This application relates to the field of hybrid vehicle technology, and more particularly to a vehicle control method, device, vehicle control equipment, and vehicle. Background Technology

[0002] With the increasing popularity of new energy vehicles, energy consumption is becoming a growing concern for users. PHEVs (Plug-in Hybrid Electric Vehicles) typically have a pure electric range of 100-200km. In urban areas, they operate primarily on electric power, with the engine rarely engaging. The engine only operates at full load at medium to high speeds or full highway speeds. However, due to the limited power supply from the vehicle's battery, pure electric driving consumes a significant amount of electricity. Therefore, reducing the energy consumption of hybrid vehicles to improve their pure electric range has become a pressing issue in this field. Summary of the Invention

[0067] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0068] In this application, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. The terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0069] The applicant discovered that when existing hybrid vehicles are used solely for electric motor drive, the engine is in standby mode while the electrical components associated with the engine remain active, thus consuming electrical energy. Similarly, when hybrid vehicles are used solely for electric motor drive, the electrical components associated with the drive motor also remain active, consuming electrical energy. In other words, existing technology lacks power control for the electrical components related to the power equipment during standby, leading to unnecessary energy loss. Therefore, by implementing power control for the electrical components related to the power equipment during standby, unnecessary energy loss can be avoided.

[0070] Example 1

[0071] like Figure 1 The diagram shown is a flowchart of a vehicle control method provided in an embodiment of this application, which can be applied to the electronic control unit (ECU) of a vehicle and includes the following steps.

[0072] S101: Determines the vehicle's driving force based on the vehicle's driving mode.

[0073] For PHEV vehicles, the drive power sources include engine drive, electric motor drive, and hybrid drive. Engine drive is powered by the engine, electric motor drive is powered by the drive motor, and hybrid drive is powered by both the engine and the drive motor. Accordingly, various driving modes can be defined for the vehicle based on the different drive power sources.

[0074] In some examples, driving modes include, but are not limited to, pure electric mode, pure electric priority mode, intelligent hybrid mode, pure fuel mode, and pure fuel priority mode.

[0075] The so-called pure electric mode uses only the electric motor to provide power to the vehicle.

[0076] The so-called pure electric priority mode uses electric motor to power the vehicle when the vehicle's operating parameters (such as battery charge) meet specified conditions (such as battery charge greater than 90%), and uses engine drive or hybrid drive to power the vehicle when the operating parameters do not meet the specified conditions.

[0077] The so-called intelligent hybrid mode (which can be simply referred to as hybrid mode) determines the output power of the engine drive and the electric drive based on the vehicle's operating parameters, so as to provide power to the vehicle based on the engine drive and the electric drive.

[0078] The so-called pure fuel mode uses only the engine to provide power to the vehicle.

[0079] The so-called pure fuel priority mode uses the engine to power the vehicle when the vehicle's operating parameters (such as the remaining fuel level) meet specified conditions (such as the remaining fuel level being greater than 90%), and uses electric motor drive or hybrid drive to power the vehicle when the operating parameters do not meet the specified conditions.

[0080] In some examples, users can determine the vehicle's driving mode by triggering a specific function key.

[0081] In one possible implementation, the user triggers the EV mode activation button, and the ECU responds to the first command matched by the EV mode button, controlling the vehicle to enter pure electric mode. In pure electric mode, the electric motor is used to provide power to the vehicle.

[0082] In one possible implementation, the user triggers the button to activate the pure electric priority mode. The ECU responds to the second command matched by the button and controls the vehicle to enter the pure electric priority mode. In the pure electric priority mode, when the vehicle's battery charge is greater than 60%, the electric motor is used to provide power to the vehicle. When the battery charge is less than or equal to 60%, hybrid drive is used to provide power to the vehicle.

[0083] In one possible implementation, the user triggers the button to activate the intelligent hybrid mode. The ECU responds to the third command matched by the intelligent hybrid button and controls the vehicle to enter the intelligent hybrid mode. In the intelligent hybrid mode, the output power of the engine drive and the electric drive are determined according to the vehicle's battery charge and remaining fuel, so as to provide power to the vehicle based on the engine drive and the electric drive.

[0084] In one possible implementation, the user triggers the button to activate the pure fuel mode, and the ECU responds to the fourth command matched by the button to control the vehicle to enter the pure fuel mode. In the pure fuel mode, the engine is used to drive the vehicle and provide power.

[0085] In one possible implementation, the user triggers the button to activate the pure fuel priority mode. The ECU responds to the fifth command matched by the button and controls the vehicle to enter the pure fuel priority mode. In the pure fuel priority mode, when the remaining fuel level of the vehicle is greater than 30%, the engine is used to provide power to the vehicle. When the remaining fuel level is less than or equal to 30%, hybrid drive is used to provide power to the vehicle.

[0086] It is important to emphasize that, in addition to user-controlled driving modes, a suitable driving mode can also be determined based on the vehicle's location information. For details on how to determine a suitable driving mode based on vehicle location information in some examples, please refer to [link to relevant documentation]. Figure 2 The steps shown are explained below.

[0087] Understandably, once the vehicle's driving mode is determined, the vehicle's driving power can be determined based on that driving mode.

[0088] Optionally, the specific process of determining the driving power of a vehicle based on its driving mode may include: if the driving mode is either pure electric mode or pure electric priority mode, the driving power is determined based on the output power of the vehicle's drive motor; if the driving mode is either pure fuel mode or pure fuel priority mode, the driving power is determined based on the output power of the vehicle's engine; if the driving mode is hybrid mode, the driving power is determined based on the output power of both the drive motor and the engine.

[0089] In some examples, the driving power of a vehicle is determined based on its driving mode. This essentially means determining which driving power source will provide power to the vehicle. Generally speaking, after determining the driving power source used by the vehicle, the specific output power of the driving power source is determined based on the throttle opening input by the user.

[0090] S102: Based on the driving force, determine the target power equipment that is currently in standby mode.

[0091] Once the vehicle's driving force is determined, the status of all its power components can be determined. For PHEV vehicles, all power components include the engine and drive motor. Therefore, based on the PHEV vehicle's driving force, the status of the engine and drive motor can be determined, and the target power component can be identified from among the various power components based on their status.

[0092] Optionally, the specific implementation process of determining the target power device currently in standby state based on the driving power may include: if the driving power does not include the output power of the engine, determining it as the target power device currently in standby state based on the engine; if the driving power does not include the output power of the drive motor, determining it as the target power device based on the drive motor.

[0093] In some examples, if the driving power includes the output power of both the engine and the drive motor, then the target power device is determined to be non-existent.

[0094] Understandably, when a vehicle is powered solely by its engine, the drive motor does not provide power output and can be considered to be in standby mode. Conversely, when a vehicle is powered solely by its electric motor, the engine does not provide power output and can be considered to be in standby mode.

[0095] S103: The electrical appliance in the vehicle that is compatible with the target power equipment is identified as the target electrical appliance.

[0096] In the case of vehicle power equipment, when the power equipment realizes the power output function, it must be equipped with electrical auxiliary equipment that matches the power equipment to realize the power output function.

[0097] In some examples, electrical components that are matched with the engine include, but are not limited to, sensors, electronic fuel injection systems, starting systems, ignition systems, and power supply systems.

[0098] In some examples, electrical components matched with the drive motor include, but are not limited to, sensors and power converters.

[0099] In one possible implementation, if the target power equipment is an engine, then the sensors, electronic fuel injection system, starting system, ignition system, and power supply system that are matched with the engine are identified as the target electrical components.

[0100] In one possible implementation, if the target power device is a drive motor, then the sensor and power converter that match the drive motor are identified as the target electrical appliances.

[0101] In related technologies, the target power equipment is in standby mode, while the electrical appliances matched with the target power equipment remain in active mode until the vehicle is powered off. In other words, during the time that the target power equipment is in standby mode, the target electrical appliances remain active, thus causing unnecessary energy consumption for the vehicle.

[0102] In some examples, after the vehicle is powered on, it is driven in pure electric mode or pure electric priority mode, leaving the engine in standby mode. The sensors, electronic fuel injection system, starting system, ignition system and power system that are matched with the engine remain active. The electrical energy consumed by the sensors, electronic fuel injection system, starting system, ignition system and power system does not bring any beneficial effect to the vehicle's power performance, but it consumes a lot of the vehicle's electrical energy, increases the vehicle's battery charge consumption rate and reduces the vehicle's electric drive range.

[0103] In some examples, after the vehicle is powered on, it is driven in pure fuel mode or pure fuel priority mode, which puts the drive motor in standby mode. The sensors and power converters matched with the drive motor remain active. The power consumption of the sensors and power converters does not have any beneficial effect on the vehicle's power performance, but it consumes a lot of the vehicle's power, which increases the rate of battery power consumption and reduces the vehicle's electric drive range.

[0104] Therefore, after identifying the target power equipment in the vehicle that is in standby mode, it is necessary to further identify the target electrical appliances based on the target power equipment, so as to control and manage the target electrical appliances that cause unnecessary power consumption.

[0105] S104: Control the target electrical appliance to be in the off state until the target power equipment switches from the standby state to the use state, then control the target electrical appliance to be in the on state to reduce the vehicle's power consumption.

[0106] The target power equipment does not remain in standby mode indefinitely. As the vehicle adjusts its driving mode, the target power equipment switches between standby and active states. Therefore, when the target power equipment is in active state, to ensure its proper functioning, the corresponding electrical components need to be activated. Conversely, during the standby period, keeping the electrical components off effectively reduces unnecessary energy consumption caused by these components, thereby reducing the vehicle's overall energy consumption.

[0107] In some examples, the vehicle has preset driving modes that users can choose from, such as Figure 3 As shown, the system includes EV mode, pure electric priority mode, and intelligent hybrid mode. When the user triggers the vehicle to enter either EV mode or pure electric priority mode, the engine is identified as the target power device, and electrical appliances that are matched with the engine are identified as target electrical appliances, which are then controlled to be turned off. When the user triggers the vehicle to switch to intelligent hybrid mode, the target electrical appliances are controlled to be turned on.

[0108] It should be noted that when controlling the state of target electrical appliances, other factors can also be considered (such as the number of target electrical appliances and the power consumption of each target electrical appliance, the vehicle's battery charge, and road conditions) to ensure that putting the target electrical appliances in the off state does not affect the vehicle's power performance. For details on the specific implementation process of controlling the state of target electrical appliances based on other factors, please refer to [link to relevant documentation]. Figure 4 , Figure 5 as well as Figure 6 The steps shown are explained below.

[0109] The processes shown in S101-S104 above determine the target power equipment in standby mode based on the vehicle's driving mode, and control the target electrical appliances that match the target power equipment to be turned off, thereby eliminating unnecessary power consumption caused by the target electrical appliances when the target power equipment is in standby mode, thus effectively reducing the vehicle's power consumption efficiency and improving the vehicle's electric drive range.

[0110] Example 2

[0111] like Figure 2 The diagram shown is a flowchart of another vehicle control method provided in this application embodiment, which can be applied to an ECU and includes the following steps.

[0112] S201: Determine the road the vehicle is currently traveling on based on the vehicle's location information.

[0113] The ECU can obtain the vehicle's location information by calling the in-vehicle multimedia navigation system.

[0114] It should be noted that when driving on various types of roads, users can refer to the road type to determine the appropriate driving mode in order to obtain a good driving experience.

[0115] In some examples, road types include, but are not limited to, highways, expressways, urban roads, rural roads, residential roads, mountain roads, and coastal roads.

[0116] S202: Determine the vehicle's driving mode based on the road the vehicle is currently traveling on.

[0117] Different types of roads present different power limitations for vehicles. Choosing a driving mode that matches the road the vehicle is currently traveling on can effectively improve the user's driving experience.

[0118] In some examples, vehicles are driving on urban roads, where road conditions are limited, speeds are low, and stop-and-go traffic is frequent, resulting in low demand for driving power. Therefore, the driving mode can be determined based on pure electric mode or pure electric priority mode.

[0119] In some examples, the vehicle is traveling on a highway at a high speed and with a high demand for driving power. Using only electric motor drive would lead to a faster rate of energy consumption. Therefore, the driving mode of the vehicle can be determined based on any one of the following: hybrid mode, pure fuel mode, or pure fuel priority mode.

[0120] In one possible implementation, the vehicle has preset selectable driving modes such as... Figure 7 As shown, the system includes EV mode, pure electric priority mode, and intelligent hybrid mode. After the vehicle is powered on, the ECU can obtain the vehicle's location information by accessing a high-precision map navigation system on the multimedia system. If the location information is located on an urban road, the vehicle is determined to be traveling on an urban road, and the driving mode can be determined based on either EV mode or pure electric priority mode. In another possible implementation, if the location information is located on a highway, the vehicle is determined to be traveling on a highway, and the driving mode can be determined based on intelligent hybrid mode.

[0121] Understandably, choosing a driving mode that matches the road conditions the vehicle is traveling in can not only provide users with a better driving experience, but also help the vehicle save energy.

[0122] The processes shown in S201-S202 above can select the appropriate driving mode for the vehicle based on the road it is traveling on, so as to ensure the user's driving experience.

[0123] Example 3

[0124] like Figure 4 The diagram shown is a flowchart of another vehicle control method provided in this application embodiment, including the following steps.

[0125] S401: Obtain the power consumption of multiple target electrical appliances.

[0126] Among them, there are multiple target electrical appliances that are matched with the target power equipment. In the relevant technology, the power consumption of each target electrical appliance is different. For the electronic components on the vehicle, the power consumption of each target electrical appliance is pre-registered in the local memory. Therefore, the power consumption of multiple target electrical appliances can be directly read from the local memory.

[0127] S402: Determine the first electrical appliance based on the power consumption of multiple target electrical appliances.

[0128] Among them, the first electrical appliance is the target electrical appliance whose power consumption meets the power consumption requirements.

[0129] In some examples, the so-called power consumption requirement can be: power consumption is greater than a specified power consumption threshold.

[0130] It should be noted that the target electrical appliance that meets the power consumption requirements is identified as the first electrical appliance. The system can select the target power with higher power consumption that can affect the vehicle's energy consumption rate from multiple target electrical appliances, and perform corresponding processing on the first electrical appliance to reduce the vehicle's energy consumption.

[0131] In one possible implementation, the target electrical appliance includes appliance A and appliance B. Appliance A has a power consumption of 500W, appliance B has a power consumption of 50W, and the specified power consumption threshold indicated by the power consumption requirement is 100W. Obviously, the power consumption of appliance A is greater than the specified power consumption threshold. Therefore, appliance A is determined to be the first electrical appliance.

[0132] In some examples, a first electrical appliance and a second electrical appliance can be determined based on the power consumption of multiple target electrical appliances. The second electrical appliance is the target electrical appliance whose power consumption does not meet the power consumption requirements. For the second electrical appliance, after the vehicle is powered on, the second electrical appliance can be controlled to be in the enabled state until the vehicle is powered off. In other words, the power consumption of the second electrical appliance is small and will not accelerate the vehicle's power consumption.

[0133] In one possible implementation, the target electrical appliance includes appliance A and appliance B. Appliance A has a power consumption of 500W, appliance B has a power consumption of 10W, and the specified power consumption threshold indicated by the power consumption requirement is 100W. Obviously, the power consumption of appliance B is less than the specified power consumption threshold, and it can be considered that the power consumption of appliance B will not accelerate the vehicle's power consumption. As a second electrical appliance, appliance B can remain in the enabled state after the vehicle is powered on.

[0134] S403: Control the first electrical appliance to be in the off state until the target power equipment switches from the standby state to the use state, then control the first electrical appliance to be in the enabled state.

[0135] Because the first electrical appliance consumes a large amount of power, it would accelerate the vehicle's battery drain. Therefore, the first electrical appliance is kept off until the target power equipment switches from standby to operating mode, at which point the first electrical appliance is put back on. In this way, when the target power equipment is in standby mode, the first electrical appliance matched with it will be off, thus avoiding unnecessary energy consumption caused by the first electrical appliance.

[0136] In one possible implementation, the first electrical appliance is appliance A, and the target power device is the engine. When the vehicle's driving mode is pure electric mode, the engine is in standby mode, and appliance A is turned off to reduce unnecessary power consumption caused by the power consumption of appliance A. When the vehicle switches from pure electric mode to hybrid mode, the engine switches from standby mode to operating mode, and appliance A needs to be turned on to ensure that the engine can be used normally.

[0137] In some examples, a corresponding relay can be pre-set on the power supply circuit of each target electrical appliance, and the power supply control of each target electrical appliance can be achieved by controlling the switching of each relay.

[0138] In one possible implementation, the first electrical appliance is appliance A. The power supply circuit to which appliance A belongs is pre-installed with a relay A. When the target power equipment is in standby mode, the relay A is controlled to open, so that appliance A is de-energized (when appliance A is de-energized, appliance A is in the off state). When the target power equipment switches from standby mode to use mode, the relay A is controlled to close, so that appliance A is energized (when appliance A is energized, appliance A is in the enabled state).

[0139] The processes shown in S401-S403 above can ensure that when the target power equipment is in standby mode, unnecessary power consumption caused by the first electrical appliance matched with the target power equipment is eliminated, thereby reducing the vehicle's power consumption and causing the vehicle's power consumption rate to decrease.

[0140] Example 4

[0141] like Figure 5 The diagram shown is a flowchart of another vehicle control method provided in this application embodiment, including the following steps.

[0142] S501: Obtain the vehicle's battery charge.

[0143] The battery power can be obtained directly from the battery controller.

[0144] S502: Determine if the battery level meets the low-power condition.

[0145] If the battery level meets the low-power condition, execute S503; otherwise, execute S504.

[0146] In some examples, the so-called power shortage condition can be: the battery level is less than a specified power threshold.

[0147] Understandably, when the battery level meets the criteria for low power, it means that the battery is not charged enough, and some electrical appliances in the vehicle that are causing unnecessary power consumption need to be shut off to reduce the vehicle's energy consumption.

[0148] S503: Control the target electrical appliance to be in the off state until the target power equipment switches from the standby state to the use state, then control the target electrical appliance to be in the enabled state.

[0149] Specifically, when the vehicle's battery level meets the low-power condition, controlling the target electrical appliance to be turned off can eliminate the power consumption caused by the target electrical appliance, thereby reducing the vehicle's power consumption rate.

[0150] S504: Control the target electrical appliance to be in the enabled state.

[0151] If the battery charge does not meet the low power condition, then the battery charge is determined to be sufficient. When the target power equipment is in standby mode, the target electrical appliance can be put into the active state to ensure that the target power equipment can be put into use at any time.

[0152] In some examples, the power-on / off control of the target electrical appliance can also be determined based on both the battery charge and the power consumption of the target electrical appliance. In one possible implementation, the target power device in standby mode is identified as the engine, and the target electrical appliances matched with the engine include appliance A and appliance B. Appliance A has a power consumption of 500W, and appliance B has a power consumption of 50W. When the vehicle's battery charge is greater than a first threshold, appliances A and B are kept in the enabled state. When the vehicle's battery charge is less than or equal to the first threshold but greater than or equal to a second threshold, appliance A is controlled to be turned off, while appliance B remains enabled. When the vehicle's battery charge is less than the second threshold, appliances A and B are controlled to be turned off. When the engine switches from standby mode to operating mode, appliances A and B are controlled to be enabled.

[0153] The processes described in S501-S504 above can ensure that the target power equipment is in standby mode and that the battery level meets the low power condition. When this condition is met, the target electrical appliance is controlled to be turned off to eliminate unnecessary power consumption caused by the target electrical appliance, thereby reducing the vehicle's power consumption and lowering the vehicle's power consumption rate.

[0154] Example 5

[0155] like Figure 6 The diagram shown is a flowchart of another vehicle control method provided in this application embodiment, including the following steps.

[0156] S601: Obtain the vehicle's driving conditions.

[0157] The road conditions of a vehicle can be determined by road images captured by image acquisition equipment, or by the vehicle's speed, braking condition, and bumpiness.

[0158] S602: If the driving conditions meet the preset high-performance operating conditions, control the target electrical appliance to be in the enabled state.

[0159] The preset high-performance usage conditions can include any one of the following scenarios: hill climbing, water wading, or off-road driving. Generally speaking, road conditions such as hill climbing, water wading, and off-road driving place high demands on the vehicle's power performance. The power provided by a single drive power source may be insufficient, and the vehicle may need to switch to another drive power source at any time (which can be understood as using hybrid drive). Therefore, when the vehicle is in any of these scenarios and the target power equipment is in standby mode, the target electrical components are activated so that the target power equipment can be used at any time, ensuring that the vehicle's power performance meets the driving conditions and improving the user experience.

[0160] In some examples, if road conditions indicate that the vehicle is in a smooth driving scenario, the target electrical appliances are turned off to reduce the vehicle's power consumption.

[0161] In some examples, the power-on / off control of the target electrical appliance can also be determined based on both battery charge and road conditions. In one possible implementation, if the target power device in standby mode is identified as the engine, and based on the vehicle's road conditions, it is determined that the vehicle is in a hill-climbing scenario and the vehicle's battery charge meets the low-power condition, then the target electrical appliance matched with the engine is activated, allowing the engine to readily engage in the vehicle's power output. In another possible implementation, if the target power device in standby mode is identified as the engine, and based on the vehicle's road conditions, it is determined that the vehicle is in a water-crossing scenario and the vehicle's battery charge does not meet the low-power condition, then the target electrical appliance matched with the engine is activated.

[0162] It is understandable that the power demand of a vehicle is higher than the energy-saving demand. When a vehicle is in a power demand scenario, priority is given to meeting the power demand to ensure that the vehicle's power performance meets the user's needs.

[0163] The processes shown in S601-S602 above can reasonably control the working status of the target electrical appliances according to the vehicle's driving conditions, so as to avoid affecting the normal use of the vehicle and ensure the user experience.
