[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0029] In the description below, words such as “first” and “second” are only used for the purpose of distinguishing the description and should not be understood as indicating or implying relative importance or order.

[0030] In related technologies, hydrogen energy, as a clean energy, has gradually become an important direction for the development of new energy. Fuel cells can convert hydrogen energy into electrical energy, and have the advantages of high power and long driving range. Hybrid vehicles are equipped with fuel cells and power batteries, which together provide energy for the vehicle. However, in the current energy management strategy of hybrid vehicles, the utilization rate of hydrogen is low, the energy consumption of the vehicle is high, and the driving range of the vehicle is poor, which affects the driving experience.

[0031] In order to solve the above problems, the present disclosure provides a vehicle control method, device, electronic device and vehicle, which can obtain the motor parameters of the vehicle, the load weight of the vehicle and the first road type information of the road on which the vehicle is traveling, and determine the target output power interval corresponding to the fuel cell of the vehicle from multiple preset output power intervals according to the motor parameters, load weight and first road type information obtained when the vehicle's operating mode is a hybrid mode, and control the vehicle's driving according to the target output power interval corresponding to the fuel cell. In this way, the vehicle load, vehicle operating conditions and the road type of the road on which the vehicle is traveling can be comprehensively considered to optimize the energy management strategy, so that the fuel cell works in a high efficiency range, which can increase the utilization rate of hydrogen, reduce the vehicle's energy consumption, and thus increase the vehicle's cruising range and improve the driving experience.

[0032] The present disclosure is described below in conjunction with specific embodiments.

[0033] Figure 1 is a flow chart of a vehicle control method according to an exemplary embodiment. Figure 1 As shown, the method can be applied to a vehicle, which is equipped with a fuel cell and a power battery, and the method may include: In step S101, when the operation mode of the vehicle is the hybrid mode, motor parameters of the vehicle, the load capacity of the vehicle and first road type information of the road on which the vehicle is traveling are obtained.

[0034] The hybrid mode indicates that the fuel cell and the power battery drive the motor of the vehicle at the same time. The motor parameter may include the motor torque, and the motor operation signal may be read by the vehicle control center to obtain the motor parameter. The load may be obtained by a pressure sensor configured by the vehicle. The first road type information indicates whether the vehicle is traveling on a highway, and the first road type information may be obtained by a positioning system configured by the vehicle.

[0035] In step S102, a target output power interval corresponding to a fuel cell of the vehicle is determined from a plurality of preset output power intervals according to the motor parameters, the load weight and the first road type information.

[0036] The plurality of preset output power intervals include a first output power interval and a second output power interval, and the upper limit value of the second output power interval is greater than the upper limit value of the first output power interval. For example, the first output power interval may be P0~60%P e The fuel cell engine is in a high-efficiency working area. The first efficiency range corresponding to the first output power interval is 50%~55%. The second output power interval can be P0~P e The second efficiency range corresponding to the second output power interval is 45%~55%, where P0 is the idle power of the fuel cell, P e is the rated power of the fuel cell.

[0037] In step S103, the vehicle is controlled to travel according to the target output power range corresponding to the fuel cell.

[0038] For example, when the fuel cell operates in the first output power range, the output power P of the fuel cell when the vehicle is running is t Satisfy P0≤P t ≤60%P e , which can reduce the energy consumption of the vehicle and thus increase the cruising range of the vehicle. Correspondingly, when the fuel cell operates in the second output power range, the output power P of the fuel cell when the vehicle is traveling t Satisfy P0≤P t ≤P e , the output power can reach the rated power, which can meet the driver's high-power driving needs.

[0039] By adopting the above method, when the vehicle's operating mode is the hybrid mode, the motor parameters of the vehicle, the vehicle's load weight, and the first road type information of the road on which the vehicle is traveling can be obtained, and the target output power interval corresponding to the vehicle's fuel cell can be determined from multiple preset output power intervals according to the obtained motor parameters, load weight, and first road type information, and the vehicle's driving can be controlled according to the target output power interval corresponding to the fuel cell. In this way, the vehicle's load weight, vehicle operating conditions, and the road type of the road on which the vehicle is traveling can be comprehensively considered to optimize the energy management strategy, so that the fuel cell works in a high-efficiency range, which can increase the utilization rate of hydrogen, reduce the vehicle's energy consumption, and thus increase the vehicle's cruising range and improve the driving experience.

[0040] In some embodiments, the above step S102 may include: determining whether the fuel cell meets a preset energy-saving condition based on the motor parameter, the load and the first road type information, and determining a target output power interval corresponding to the fuel cell from a plurality of preset output power intervals based on whether the fuel cell meets the preset energy-saving condition. For example, the following situations may be included: Case 1: When it is determined that the fuel cell meets the preset energy-saving condition according to the motor parameters, the load and the first road type information, the target output power interval corresponding to the fuel cell is determined from the first output power interval and the second output power interval according to the second road type information of the road on which the vehicle is traveling. The second road type information indicates whether the road on which the vehicle is traveling is an uphill road, and the second road type information can be obtained through a positioning system configured for the vehicle.

[0041] In some possible implementations, when the second road type information indicates that the road on which the vehicle is traveling is a non-uphill road, the first output power interval is used as the target output power interval.

[0042] Among them, non-uphill roads include flat roads and downhill roads. In this scenario, the fuel cell meets the energy-saving conditions and the vehicle's required power is low. The fuel cell works in a high-efficiency range, which can increase the utilization rate of hydrogen, reduce vehicle energy consumption, and thus increase the vehicle's cruising range.

[0043] In some other possible implementations, when the second road type information indicates that the road on which the vehicle is traveling is an uphill road, the second output power interval is used as the target output power interval.

[0044] For example, in this scenario, although the fuel cell meets the energy-saving conditions, the vehicle's required power is high, and the output power of the fuel cell needs to reach the rated power. When the positioning system configured in the vehicle obtains that the vehicle is located on an uphill road or is about to enter an uphill road within a preset time period, such as 2 seconds, the second output power interval can be used as the target output power interval to meet the vehicle's uphill power demand.

[0045] Case 2: When it is determined that the fuel cell does not meet the preset energy-saving conditions based on the motor parameters, the load weight and the first road type information, the second output power range is used as the target output power range so that the output power of the fuel cell can reach the rated power and meet the driver's high-power driving needs.

[0046] In some embodiments, when the vehicle is in a non-cruise mode, it can be determined whether the fuel cell meets a preset energy-saving condition based on the motor parameters, the load weight and the first road type information.

[0047] Among them, the cruise control can be a device that automatically controls the vehicle's driving speed. The driver can determine whether to turn on the cruise control mode based on the current vehicle driving scenario. For example, if the driver does not turn on the cruise control mode based on scenarios such as complex roads, it is necessary to determine whether the fuel cell meets the preset energy-saving conditions based on the motor parameters, the load weight and the first road type information, so as to determine the target output power range and optimize the energy management strategy.

[0048] In this step, the preset energy-saving conditions include: the motor torque is greater than or equal to a first preset torque threshold and less than a second preset torque threshold; the load is less than a preset load threshold; and the first road type information indicates that the vehicle is traveling on a non-highway road.

[0049] The first preset torque threshold may be 0, and the second preset torque threshold may be 70%N. e , N e is the rated torque of the vehicle motor, the preset load threshold can be 90%W e , W e is the rated load of the vehicle, and the non-highway road may include urban roads and rural roads. For example, it can be determined that the motor torque N satisfies 0≤N<70%N at the same time. e , load W satisfies W ≥ 90% W e , the vehicle is on an urban road or a rural road, and it is determined that the fuel cell meets the preset energy-saving conditions. Correspondingly, when it is determined that the motor torque N does not meet 0≤N<70%N e , or load W<90%W e, or the vehicle is on a highway. At this time, the vehicle's power demand is large, and the output power of the fuel cell needs to meet the driver's high-power driving needs, which does not meet the preset energy-saving conditions.

[0050] In other embodiments, when the vehicle enters the cruise control mode, the cruise control speed may be acquired, and the target output power range of the fuel cell may be determined according to the cruise control speed.

[0051] Among them, when the vehicle enters the cruise control mode, the scene where the vehicle is located is relatively simple at this time, and the factors that affect the output power of the fuel cell can be excluded, and the target output power range can be determined according to the cruise control speed. For example, if the cruise control speed is less than the preset speed value, the required power of the vehicle is low at this time, and the first output power range can be used as the target output power range, so that the fuel cell engine is in a high-efficiency working area, reducing the energy consumption of the vehicle, and thus increasing the cruising range of the whole vehicle. Correspondingly, if the cruise control speed is greater than or equal to the preset speed value, the second output power range can be used as the target output power range, so that the output power of the fuel cell can reach the rated power to meet the high-power driving requirements. The preset speed value can be obtained based on the actual situation of the vehicle in combination with historical data. For example, the preset speed value can be set to 60km / h.

[0052] In some embodiments, when the operating state of the power battery of the vehicle is switched from the running state to the standby state, the motor parameters of the vehicle, the load capacity of the vehicle, and the first road type information of the road on which the vehicle is traveling can be obtained.

[0053] For example, when the vehicle's operating mode is a hybrid mode, it can be determined first whether the fuel cell has entered an operating state. When the fuel cell has not entered an operating state due to a malfunction, power is output by the power battery to drive the vehicle. When the fuel cell enters an operating state, before obtaining the vehicle's motor parameters, the vehicle's load weight, and the first road type information of the vehicle's driving road, and determining the target output power range corresponding to the fuel cell based on the acquired motor parameters, load weight, and first road type information, the relay between the power battery and the vehicle control center can be disconnected, so that the working state of the power battery is switched from an operating state to a standby state, and power is output by the fuel cell engine to drive the vehicle, thereby improving the utilization rate of the fuel cell engine and reducing vehicle energy consumption.

[0054] In some embodiments, when the power battery meets a preset charging condition, the working state of the power battery can be switched from a standby state to a charging state.

[0055] The preset charging condition includes any one of the following: the motor torque is less than a first preset torque threshold; the motor torque is greater than or equal to a second preset torque threshold; the vehicle is traveling on an uphill road; the power battery SOC (State of charge) value is less than a preset SOC threshold. For example, the first preset torque threshold may be 0, and the second preset torque threshold may be 70%N e , N e is the rated torque of the vehicle motor. When the motor torque is less than the first preset torque threshold, or when the motor torque is greater than or equal to the second preset torque threshold, the vehicle can convert the released kinetic energy into electrical energy through the motor to charge the power battery. When the vehicle is on an uphill road, the remaining power of the fuel cell engine output power after meeting the vehicle's required power is used to charge the power battery. The long-distance signal of the power battery can be read by the vehicle control center to obtain the SOC value of the power battery. The SOC threshold can be 40%. When the SOC value is less than 40%, the working state of the power battery is switched to the charging state so as to recycle the energy during the vehicle's driving and charge the power battery. It should be noted that when the working state of the power battery is the charging state, the SOC value of the power battery is obtained in real time, and when the SOC value rises to a preset power threshold such as 85%, the working state of the power battery is switched from the charging state to the standby state to avoid overcharging of the power battery and affecting the battery life.

[0056] Figure 2 is a flow chart of another vehicle control method according to an exemplary embodiment. Figure 2 As shown, the method includes: S201. When the operation mode of the vehicle is the hybrid mode, the operation state of the power battery is switched from the operation state to the standby state.

[0057] Among them, the relay between the power battery and the vehicle control center can be disconnected, so that the working state of the power battery is switched from the running state to the standby state.

[0058] S202: Determine whether the vehicle is in a cruise control mode.

[0059] Wherein, when the vehicle is in a non-cruise mode, step S203 is executed; When the vehicle is in the cruise control mode, step S206 is executed.

[0060] S203, obtaining motor parameters of the vehicle, the load capacity of the vehicle, and first road type information of the road on which the vehicle is traveling.

[0061] Among them, the motor parameters may include motor torque, which can be obtained through a vehicle control center, the load weight can be obtained through a pressure sensor configured by the vehicle, and the first road type information can be obtained through a positioning system configured by the vehicle.

[0062] S204: Determine whether the fuel cell meets a preset energy-saving condition based on the motor parameters, the load weight, and the first road type information.

[0063] The preset energy-saving condition includes: the motor torque is greater than or equal to a first preset torque threshold and less than a second preset torque threshold, the first preset torque threshold is 0, and the second preset torque threshold is 70%N e , N e is the rated torque of the vehicle motor; the load is less than the preset load threshold, which is 90%W e , W e is the rated load of the vehicle; the first road type information indicates that the road the vehicle is traveling on is a non-highway road.

[0064] If it is determined that the fuel cell meets the preset energy-saving condition, step S205 is executed; or, When it is determined that the fuel cell does not meet the preset energy-saving condition, step S209 is executed.

[0065] S205: Determine whether the road the vehicle is traveling on is an uphill road.

[0066] If the vehicle is traveling on an uphill road, execute step S209; or, When the road on which the vehicle is traveling is not an uphill road, step S208 is executed.

[0067] S206: Obtain the cruise speed.

[0068] S207: Determine whether the cruise control speed is less than a preset speed value.

[0069] Among them, the preset speed value is 60km / h.

[0070] When the cruise speed is less than the preset speed value, executing step S208; When the cruise speed is greater than or equal to the preset speed value, step S209 is executed.

[0071] S208: Using the first output power interval as the target output power interval corresponding to the fuel cell.

[0072] The first output power range may be P0~60%P e , P0 is the idle power of the fuel cell, Pe is the rated power of the fuel cell, the fuel cell engine is in a high-efficiency working area, and the first efficiency range corresponding to the first output power interval is 50%-55%.

[0073] S209: Use the second output power interval as the target output power interval corresponding to the fuel cell.

[0074] The second output power range may be P0~P e The second efficiency range corresponding to the second output power interval is 45%~55%.

[0075] S210 , controlling the vehicle to travel according to the target output power range corresponding to the fuel cell.

[0076] By adopting the above scheme, when the vehicle's operating mode is a hybrid mode, the working state of the power battery can be switched to a standby state, and when the vehicle is in a non-cruise mode, by obtaining the vehicle's motor parameters, the vehicle's load weight, and the first road type information of the vehicle's driving road, and according to the obtained motor parameters, load weight, and first road type information, the target output power interval corresponding to the vehicle's fuel cell can be determined from multiple preset output power intervals. At the same time, when the vehicle is in a cruise mode, the target output power interval corresponding to the fuel cell can be determined according to the cruise speed, and the vehicle can be controlled according to the determined target output power interval. In this way, according to the vehicle's operating conditions, the load weight and the road type of the vehicle's driving road can be comprehensively considered to optimize the energy management strategy, so that the power battery is in standby mode and the fuel cell works in a high-efficiency range, which can improve the utilization rate of the fuel cell engine, increase the utilization rate of hydrogen, reduce the vehicle's energy consumption, and thus increase the vehicle's cruising range and improve the driving experience.

[0077] It should be noted that the above Figure 2 For the relevant description of each step in the illustrated embodiment, reference can be made to the description of the relevant steps in the aforementioned embodiment, which will not be repeated here.
