[0046] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure.

[0047] It is understood that the terms "first", "second", etc. in this disclosure are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other and do not indicate a specific order or importance.

[0048] It is further understood that although operations are described in a particular order in the drawings in the embodiments of the present disclosure, this should not be construed as requiring that the operations be performed in the particular order shown or in a serial order, or that all of the operations shown be performed to obtain the desired results. In certain circumstances, multitasking and parallel processing may be advantageous.

[0049] FIG1 is a flow chart of a vehicle control method according to an exemplary embodiment. As shown in FIG1 , the method includes:

[0050] In step S11 , the state of charge (SOC) value of the vehicle's power battery is obtained.

[0051] In step S12 , when the SOC value is outside the first preset range, 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 range.

[0052] 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.

[0053] 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. The state of charge (SOC) value of the power battery of the vehicle is obtained, and the SOC value is compared with a first SOC value preset interval. When the SOC value is outside the first preset interval, the fuel cell is adjusted 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 Seven most economical power points are initially set. When the vehicle is in the ignition state and in D / R gear, the vehicle's fuel cell operates at the pre-set fourth most economical power point. The vehicle's SOC value is obtained. Assuming that the first preset range is between 50% and 80%, when the vehicle's SOC value is outside the first preset range, the vehicle's fuel cell is adjusted to operate at the most economical power point one gear higher or lower, so that the vehicle's SOC value returns to the first preset range, reducing hydrogen consumption caused by transient fuel cell operation. At the same time, the fuel cell temperature rise is reduced, thereby improving battery life.

[0054] Optionally, step S11 includes:

[0055] When the vehicle is in a running state, a state of charge (SOC) value of a power battery of the vehicle is obtained.

[0056] 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.

[0057] 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 a first preset range, 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 range. By comparing the vehicle's power battery's state of charge (SOC) value with the first preset range and, when the SOC value is outside the first preset range, adjusting the output power of the vehicle's fuel cell according to the SOC value so that the vehicle's SOC value is within the first preset range, this avoids the high throughput, high temperature rise, and short life of the power battery caused by large fluctuations in the vehicle's power battery SOC value, as well as the reduction in vehicle power performance at low SOC values, thereby reducing the vehicle's hydrogen fuel energy consumption.

[0058] FIG2 is a flow chart of another vehicle control method according to an exemplary embodiment. As shown in FIG2 , step S12 includes:

[0059] In step S1201 , within a preset time period, it is determined that the SOC value is less than a first lower limit of a first preset interval for a first number of times.

[0060] 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.

[0061] 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, the first number of times that the SOC value is less than the lower limit of the first preset interval within the 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 currently operating most economical power point, 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 the interval of 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 performance of the vehicle's power battery is insufficient. By adjusting the output power of the current fuel cell to the 4th most economical power point, the fuel cell operates at the 5th most economical power point with a higher 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 conditions of the stack, improving the battery life, and reducing the battery temperature rise.

[0062] FIG3 is a flow chart of another vehicle control method according to an exemplary embodiment. As shown in FIG3 , step S12 includes:

[0063] In step S1203 , within a preset time period, it is determined that the second number of times the SOC value is greater than the upper limit of the first preset interval is exceeded.

[0064] 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, which is lower than the current output power.

[0065] 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 second number of times that the SOC value is greater than the upper limit of the interval 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 current most economical power point, and the second output power is less than the current output power; for example: when the vehicle is in operation, 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 the interval of 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 so that the fuel cell operates at the 3rd most economical power point of the output power of a smaller gear. 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 the battery life, and reducing the battery temperature rise.

[0066] FIG4 is a flow chart of another vehicle control method according to an exemplary embodiment. As shown in FIG4 , step S12 includes:

[0067] In step S1205, when the duration of the SOC value being less than the lower limit of the first preset interval reaches a first preset time, a first average value of the vehicle required power is periodically obtained.

[0068] 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 designated SOC value.

[0069] 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 required power 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 within the first preset interval. The power adjustment is then stopped, thereby reducing the hydrogen consumption caused by the transient operating conditions of the stack, improving battery life, and reducing battery temperature rise.

[0070] FIG5 is a flow chart of another vehicle control method according to an exemplary embodiment. As shown in FIG5 , step S12 includes:

[0071] 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.

[0072] 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.

[0073] 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, the second average value of the vehicle's required power 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, 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 vehicle's fuel cell has 7 most economical power points. When the vehicle's SOC value 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 fuel cell's power demand in the latter 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 fuel cell's power demand 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 within 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.

[0074] Optionally, step S12 includes:

[0075] Method 1: When the SOC value is less than a first preset threshold, the fuel cell is controlled to output maximum power; or,

[0076] Method 2: When the SOC value is greater than a second preset threshold, controlling the fuel cell to idle; or,

[0077] Method 3: When the SOC value is greater than a third preset threshold, the fuel cell is controlled to stop working; or,

[0078] 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.

[0079] Exemplarily, the SOC value of the vehicle is compared with a plurality of preset thresholds, which are SOC values ​​corresponding to various operating conditions of the vehicle. The operating state of the vehicle is determined based on the comparison results of 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 throughput of the power battery 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 to prevent the battery from being overcharged due to slow transient response of the fuel cell, reduce the hydrogen consumption caused by transient operating conditions 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 less 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 overhead caused by the transient operating condition of the stack, improving battery life, and reducing battery temperature rise.

[0080] Optionally, when the vehicle is in a parked condition, the fuel cell of the vehicle is idling.

[0081] For example, when the vehicle is parked, the fuel cell of the vehicle is idling, which avoids frequent starts and stops of the fuel cell system, thereby better protecting the life of the fuel cell.

[0082] 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 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.

[0083] FIG6 is a block diagram of a vehicle control device 600 according to an exemplary embodiment. As shown in FIG6 , the vehicle control device 600 includes an acquisition module 601 and an adjustment module 602 .

[0084] An acquisition module 601 is used to obtain the state of charge (SOC) value of the vehicle's power battery;

[0085] The adjustment module 602 is configured to adjust the current output power of the fuel cell according to the SOC value when the SOC value is outside a first preset range, so that the SOC value is within the first preset range.

[0086] Optionally, the adjustment module 602 is configured to:

[0087] 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;

[0088] 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.

[0089] Optionally, the adjustment module 602 is configured to:

[0090] Determining a second number of times that the SOC value is greater than an upper limit of the first preset interval within a preset time period;

[0094] adjusting the current output power to a third output power, and using the third output power as the output power of the fuel cell in the next cycle until the SOC value reaches a first specified SOC value;

[0095] The third output power is greater than the first average value, and the first specified SOC value is a value within the first preset range.

[0096] Optionally, the adjustment module 602 is configured to:

[0099] The fourth output power is less than the second average value, and the second specified SOC value is a value within the first preset range.

[0100] Optionally, the adjustment module 602 is configured to:

[0105] Optionally, the acquisition module 601 is configured to:

[0106] When the vehicle is in a running state, a state of charge (SOC) value of a power battery of the vehicle is obtained.

[0107] 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 throughput, large temperature rise, short life of the power battery and reduced vehicle power performance 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.
