[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0046] It is understood that the terms "first", "second", etc. in the present disclosure are used to describe various information, but these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or importance.

[0047] It is further understood that, although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring the execution of all the operations shown to obtain the desired results. In certain environments, multitasking and parallel processing may be advantageous.

[0048] Figure 1 is a flow chart of a vehicle control method according to an exemplary embodiment. Figure 1 As shown, the method includes:

[0049] In step S11 , the state of charge (SOC) value of the power battery of the vehicle is obtained.

[0050] In step S12, when the SOC value is outside the first preset interval, the current output power of the fuel cell is adjusted according to the SOC value so that the SOC value is within the first preset interval.

[0051] Exemplarily, the vehicle can pre-set multiple most economical power points, which are the values ​​corresponding to the power battery SOC when the vehicle's fuel cell outputs maximum power. They are multiple fixed values ​​pre-given by the manufacturer when the fuel cell used in the vehicle leaves the factory.

[0052] The fuel cell of the vehicle has the most economical power points of multiple gears. When the vehicle is ignited, the fuel cell of the vehicle operates at the pre-set most economical power point, obtains the state of charge SOC value of the power battery of the vehicle, compares the SOC value with the first SOC value preset interval, and when the SOC value is outside the first preset interval, adjusts the fuel cell to operate at the most economical power point of a higher gear or a lower gear according to the SOC value, so that the SOC value returns to the first preset interval; for example: assuming that the fuel cell of the vehicle can be pre-set First, 7 most economical power points are set. When the vehicle is in the ignition state and the D / R gear is engaged, the fuel cell of the vehicle operates at the pre-set fourth most economical power point, and the SOC value of the vehicle is obtained. Assuming that the first preset interval is 50% to 80%, when the SOC value of the vehicle is outside the first preset interval compared with the first preset interval, the fuel cell of the vehicle is adjusted to operate at the most economical power point of a higher gear or a lower gear, so that the SOC value of the vehicle returns to the first preset interval, reducing the hydrogen consumption caused by the transient working condition of the stack. At the same time, the temperature rise of the stack is reduced, and the battery life is improved.

[0053] Optionally, step S11 includes:

[0054] When the vehicle is in a running state, a state of charge (SOC) value of a power battery of the vehicle is obtained.

[0055] Exemplarily, when the vehicle is in an ignition state and the vehicle is in D / R gear, the vehicle is in a running state, and the state of charge SOC value of the power battery of the vehicle is obtained.

[0056] Through the above technical solution, the state of charge SOC value of the vehicle's power battery is obtained; when the SOC value is outside the first preset interval, the current output power of the fuel cell is adjusted according to the SOC value so that the SOC value is within the first preset interval. By comparing the state of charge SOC value of the vehicle's power battery with the first preset interval, and when the SOC value is outside the first preset interval, the output power of the vehicle's fuel cell is adjusted according to the SOC value so that the SOC value of the vehicle is within the first preset interval, the situation of high power battery throughput, large temperature rise, and short life due to large fluctuations in the vehicle's power battery SOC value is avoided, and the situation of reduced vehicle power performance at low SOC values ​​is avoided, thereby reducing the vehicle's hydrogen fuel energy consumption.

[0057] Figure 2 is a flow chart of another vehicle control method according to an exemplary embodiment. Figure 2 As shown, step S12 includes:

[0058] In step S1201, within a preset time period, it is determined that the SOC value is less than a first lower limit of the first preset interval for a first time.

[0059] In step S1202, when the first number is greater than or equal to a first preset number threshold, the current output power is adjusted to a first output power, and the first output power is greater than the current output power.

[0060] Exemplarily, when the vehicle is in the ignition state and the vehicle is in D / R gear, the fuel cell of the vehicle operates at a preset most economical power point, the state of charge SOC value of the power battery of the vehicle is obtained, and the first number of times that the SOC value is less than the lower limit of the first preset interval within a preset time period is confirmed, and the first number is compared with the first preset number threshold. When the first number is greater than or equal to the first preset number threshold, the current output power is adjusted to the first output power. The fuel cell operates at the most economical power point that is one gear higher than the most economical power point of the current operation, and the first output power is greater than the current output power; for example: when the vehicle is in operation, the SOC value of the vehicle is obtained, and the current vehicle SOC value is below The output power of the fuel cell power of the vehicle is the 4th most economical power point. Assuming that the first preset interval is 50% to 80%, determine the first number of times that the SOC value is less than 50% within the preset time period. Assuming that the first preset number threshold is 2, when the first number of times that the SOC value is less than 50% within the preset time period is obtained to be 2 or greater than 2, the power of the vehicle's power battery is insufficient. By adjusting the current fuel cell's output power to the 4th most economical power point, the fuel cell operates at a higher output power of the 5th most economical power point. The fuel cell power is at a stable power point most of the time, reducing the hydrogen consumption overhead caused by the transient operating conditions of the stack, improving battery life, and reducing battery temperature rise.

[0061] Figure 3 is a flow chart of another vehicle control method according to an exemplary embodiment. Figure 3 As shown, step S12 includes:

[0062] In step S1203, within a preset time period, it is determined that the SOC value is greater than a second number of times of the upper limit of the first preset interval.

[0063] In step S1204, when the second number is greater than or equal to a second preset number threshold, the current output power is adjusted to a second output power, and the second output power is less than the current output power.

[0064] Exemplarily, when the vehicle is in the ignition state and the vehicle is in D / R gear, the fuel cell of the vehicle operates at the pre-set most economical power point, the state of charge SOC value of the power battery of the vehicle is obtained, and the second number of times that the SOC value is greater than the interval upper limit value of the first preset interval within the preset time period is confirmed, and the second number is compared with the second preset number threshold. When the second number is greater than or equal to the second preset number threshold, the current output power is adjusted to the second output power, and the fuel cell operates at the most economical power point that is one gear lower than the most economical power point currently running, and the second output power is less than the current output power; for example: when the vehicle is in the running state, the SOC value of the vehicle is obtained, and the current The output power of the fuel cell power of the vehicle under the vehicle SOC value is the 4th most economical power point, assuming that the first preset interval is 50% to 80%, determine the second number of times that the SOC value is greater than 80% within the preset time period, assuming that the second preset number threshold is 2, when the second number of times that the SOC value is greater than 80% within the preset time period is obtained to be 2 or a value greater than 2, the 4th most economical power point of the output power of the current fuel cell is adjusted to make the fuel cell operate at the 3rd most economical power point with a smaller output power. The fuel cell power is at a stable power point most of the time, reducing the hydrogen consumption overhead caused by the transient operating condition of the fuel cell stack, improving the battery life, and reducing the battery temperature rise.

[0065] Figure 4 is a flow chart of another vehicle control method according to an exemplary embodiment. Figure 4 As shown, step S12 includes:

[0066] In step S1205, when the duration of the SOC value being less than the lower limit of the first preset interval reaches the first preset time, a first average value of the vehicle required power is periodically obtained.

[0067] In step S1206, the current output power is adjusted to a third output power, and the third output power is used as the output power of the fuel cell in the next cycle until the SOC value reaches a first specified SOC value.

[0068] Exemplarily, when the vehicle is in the ignition state and the vehicle is in D / R gear, when the SOC value is less than the lower limit of the first preset interval and the duration reaches the first preset time, the first average value of the vehicle's total vehicle power demand within a preset period is obtained, the current output power is adjusted to a third output power that is one level higher than the first average value, and the third output power is used as the output power of the fuel cell in the next period, the SOC value of the vehicle is determined in the next period, and when the SOC value reaches a first specified SOC value, the power adjustment is stopped; wherein, the third output power is greater than the first average value, and the first specified SOC value is a value within the first preset interval. For example: assuming that the first preset interval is 50% to 80%, the fuel cell of the vehicle has 7 most economical power points. When the SOC value of the vehicle is less than 50%, the first preset time is 1 minute. The first average value of the vehicle's total power demand is calculated every 1 minute. The power demand of the fuel cell in the next minute is the most economical power point that is one level higher than the average power demand of the vehicle in the previous minute. That is, when the average power demand of the vehicle is less than the 4th most economical power point but greater than the 3rd most economical power point, the power demand of the fuel cell is the 4th most economical power point. The output power of the fuel cell is adjusted until the SOC value is the specified SOC value in the first preset interval. That is, the power adjustment is stopped, thereby reducing the hydrogen consumption caused by the transient operating conditions of the fuel cell stack, improving battery life, and reducing battery temperature rise.

[0069] Figure 5 is a flow chart of another vehicle control method according to an exemplary embodiment. Figure 5 As shown, step S12 includes:

[0070] In step S1207, when the duration of the SOC value being greater than the lower limit of the first preset interval reaches a second preset time, a second average value of the vehicle required power is periodically obtained.

[0071] In step S1208, the current output power is adjusted to a fourth output power, and the fourth output power is used as the output power of the fuel cell in the next cycle until the SOC value reaches a second specified SOC value.

[0072] Exemplarily, when the vehicle is in the ignition state and the vehicle is in D / R gear, when the SOC value is greater than the lower limit of the first preset interval and the duration reaches a second preset time, a second average value of the vehicle's total vehicle power demand within a preset period is obtained, the current output power is adjusted to a fourth output power that is one level lower than the first average value, and the fourth output power is used as the output power of the fuel cell in the next period, and the SOC value of the vehicle is obtained in the next period, and when the SOC value reaches a second specified SOC value, the power adjustment is stopped; wherein, the fourth output power is less than the second average value, and the second specified SOC value is a value within the first preset interval. For example: assuming that the first preset interval is 50% to 80%, the fuel cell of the vehicle has 7 most economical power points. When the SOC value of the vehicle is greater than 80%, the second preset time can be 1 minute. The second average value of the vehicle's total power demand is calculated every 1 minute. The power demand of the fuel cell in the next minute is the most economical power point that is one level lower than the average power demand of the vehicle in the previous minute. That is, when the average power demand of the vehicle is greater than the 4th most economical power point but less than the 5th most economical power point, the power demand of the fuel cell is the 4th most economical power point. The output power of the fuel cell is adjusted until the SOC value is the specified SOC value in the first preset interval. That is, the power adjustment is stopped. This can reduce the hydrogen consumption overhead caused by the transient operating conditions of the stack and reduce the temperature rise of the stack.

[0073] Optionally, step S12 includes:

[0074] Mode 1: When the SOC value is less than a first preset threshold, the fuel cell is controlled to output maximum power; or,

[0075] Mode 2: When the SOC value is greater than a second preset threshold, the fuel cell is controlled to idle; or,

[0076] Mode 3: When the SOC value is greater than a third preset threshold, the fuel cell is controlled to stop working; or,

[0077] The first preset threshold is smaller than the lower limit of the first preset interval, the second preset threshold is larger than the upper limit of the first preset interval, and the second preset threshold is smaller than the third preset threshold.

[0078] Exemplarily, the SOC value of the vehicle is compared with a plurality of preset thresholds, the plurality of thresholds being the SOC values ​​corresponding to the vehicle under various operating conditions. The operating state of the vehicle is determined according to the comparison result between the SOC value and the preset thresholds. When the first preset threshold is less than the lower limit of the first preset interval, the power of the power battery of the vehicle is insufficient, and the fuel cell is controlled to output the maximum power so that the power battery throughput of the vehicle is maintained within a stable interval. When the second preset threshold is greater than the upper limit of the first preset interval, the fuel cell is controlled to idle. When the SOC value is greater than the third preset threshold, the fuel cell is controlled to stop working, so as to prevent the battery from being overcharged due to the slow transient response of the fuel cell, reduce the hydrogen consumption caused by the transient operating condition of the stack, improve the battery life, and reduce the battery temperature rise. The second preset threshold is less than the third preset threshold. For example: assuming that the third preset threshold is greater than the third preset threshold, for example: A preset interval is 50% to 80%, the first preset threshold is less than the lower limit of the first preset interval, and the second preset threshold is greater than the upper limit of the first preset interval. Assuming that the first preset threshold of the vehicle is 30%, the second preset threshold of the vehicle is 90%, and the third preset threshold of the vehicle is 95%, when the SOC value is less than 30%, the fuel cell is controlled to output maximum power, when the SOC value is greater than 90%, the fuel cell is controlled to idle, and when the SOC value is greater than 95%, the fuel cell is controlled to idle. The current operating condition of the vehicle is predicted based on the SOC, and the most appropriate stable power point is selected to provide energy for the entire vehicle to prevent battery overcharging caused by slow transient response of the fuel cell, so that the vehicle's power battery throughput is maintained within a stable range, reducing the hydrogen consumption caused by the transient operating condition of the stack, improving battery life, and reducing battery temperature rise.

[0079] Optionally, when the vehicle is in a parked condition, the fuel cell of the vehicle is idling.

[0080] Exemplarily, when the vehicle is in a parking condition, the fuel cell of the vehicle is idling, which avoids frequent starting and stopping of the fuel cell system, thereby better protecting the life of the fuel cell.

[0081] In the above technical solution, by comparing the state of charge SOC value of the vehicle's power battery with a first preset interval, and when the SOC value is outside the first preset interval, adjusting the output power of the vehicle's fuel cell according to the SOC value, the SOC value of the vehicle is made to be within the first preset interval, thereby avoiding the high throughput, large temperature rise and short life of the power battery caused by large fluctuations in the vehicle's power battery SOC value, and avoiding the reduction in vehicle power performance at low SOC values, thereby reducing the vehicle's hydrogen fuel energy consumption.

[0082] Figure 6 is a block diagram of a vehicle control device 600 according to an exemplary embodiment. Figure 6As shown, the vehicle control device 600 includes an acquisition module 601 and an adjustment module 602 .

[0083] The acquisition module 601 is used to acquire the state of charge (SOC) value of the power battery of the vehicle;

[0084] The adjustment module 602 is used to adjust the current output power of the fuel cell according to the SOC value when the SOC value is outside the first preset interval, so that the SOC value is within the first preset interval.

[0085] Optionally, the adjustment module 602 is used to:

[0086] Determine a first number of times that the SOC value is less than a lower limit of the first preset interval within a preset time period;

[0087] When the first number is greater than or equal to a first preset number threshold, the current output power is adjusted to a first output power, and the first output power is greater than the current output power.

[0088] Optionally, the adjustment module 602 is used to:

[0089] Determine a second number of times that the SOC value is greater than an upper limit value of the first preset interval within a preset time period;

[0090] When the second number is greater than or equal to a second preset number threshold, the current output power is adjusted to a second output power, and the second output power is less than the current output power.

[0094] The third output power is greater than the first average value, and the first specified SOC value is a value within the first preset interval.

[0095] Optionally, the adjustment module 602 is used to:

[0096] When the duration of the SOC value being greater than the lower limit of the first preset interval reaches a second preset time, periodically obtaining a second average value of the vehicle required power;

[0102] When the SOC value is greater than a third preset threshold, the fuel cell is controlled to stop working; or,

[0103] The first preset threshold is smaller than the lower limit of the first preset interval, the second preset threshold is larger than the upper limit of the first preset interval, and the second preset threshold is smaller than the third preset threshold.

[0104] Optionally, the acquisition module 601 is used to:

[0105] When the vehicle is in a running state, a state of charge (SOC) value of a power battery of the vehicle is obtained.

[0106] In the above technical solution, by comparing the state of charge SOC value of the vehicle's power battery with a first preset interval, and when the SOC value is outside the first preset interval, adjusting the output power of the vehicle's fuel cell according to the SOC value, so that the SOC value of the vehicle is within the first preset interval, the high power battery throughput, large temperature rise, short life and reduced vehicle power at low SOC values ​​caused by large fluctuations in the vehicle's power battery SOC value are avoided, thereby reducing the vehicle's hydrogen fuel energy consumption.
