The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
The following describes a control method and apparatus of a vehicle, and a storage medium of an embodiment of the present invention with reference to the accompanying drawings. Aiming at the problems that a fuel cell system lacks a working condition prediction function in the related art, a vehicle adopts a power request mode under a continuous climbing of a plateau, continuous peak power output easily causes a thermal management fault or even a stop of the vehicle and service life of a fuel cell stack is reduced in the related art, the invention provides a control method of the vehicle.

Based on the complexity of the domestic highway working conditions, the road working conditions are roughly divided into working conditions such as high altitude, plain, continuous climbing, continuous downhill, combined ascending and descending, and the like, and the working conditions of the highway and the common highway almost cover all roads in China. Because of the power output specificity of the fuel cell system, all fuel cell heavy trucks can only run on roads with a slow gradient and an altitude below 2000 meters at present, and can not meet the requirements of continuous climbing, plateau climbing and other roads, but if the front road working condition can be predicted in advance by utilizing a vehicle intelligent network system according to the driving habit of a user, the energy management mode can be adjusted in advance for the front road working condition, so that the vehicle can keep the optimal state of the vehicle energy before entering the working condition, the power of the fuel cell system can be efficiently output, the peak power output time of the fuel cell system can be reduced, the service life of a fuel cell stack can be prolonged, the torque of the vehicle can be increased, and the vehicle can not be stopped due to insufficient electric quantity of the power cell system under the continuous climbing or complex working condition.
Specifically, fig. 1 is a schematic flow chart of a vehicle control method according to an embodiment of the present invention.
As shown in fig. 1, the control method of the vehicle includes the steps of:
In step S101, a current amount of electricity of a current vehicle, an altitude value of a road ahead, and a gradient value are acquired.
The elevation value refers to the height of the front road, and the gradient value comprises a climbing gradient value, a climbing length value, a downhill gradient value, a downhill length value and a gradient angle value of the front road.
It should be appreciated that prior to acquiring the current charge of the current vehicle, the altitude value and the grade value of the road ahead, the vehicle intelligent network system acquires the current speed, the current road information and the driving mode of the current vehicle in advance, and predicts the road information of the road ahead, including the altitude value, the grade value and the traffic light condition, based on the current road information and the driving mode. The current road information comprises traffic light conditions, traffic flow information, congestion conditions, road types and the like, and the driving mode can be an energy-saving mode, a common mode and a movement mode.
Specifically, the vehicle intelligent network system collects road information such as traffic light conditions, traffic flow information, congestion conditions, road types and the like of the current road, and predicts information such as altitude values, gradient values, traffic light conditions and the like of the road in front of the current vehicle in a driving mode, as shown in fig. 2 (a).
In step S102, when the altitude value is greater than a first preset threshold, it is determined whether there is a first target position whose gradient value is greater than a second preset threshold.
The first target position with the gradient value larger than the second preset threshold value is the position of the climbing road.
It should be understood that the altitude refers to a vertical distance of a place on the ground above the sea level, and is generally set to a high altitude of 1500-3500 m, and the first preset threshold may be set to 1500 m, and if the altitude value of the road ahead of the current vehicle exceeds 1500 m, it is indicated that the road ahead of the current vehicle is a high altitude road.
The second preset threshold may be a threshold preset by the user, may be a threshold obtained through limited experiments, or may be a threshold obtained through limited computer simulation, which is not particularly limited herein.
In step S103, if the first target position exists, a first power control parameter of the fuel cell system is determined according to the altitude value and the current electric quantity, the fuel cell system is controlled according to the first power control parameter, and the current vehicle is switched to a preset power request mode when the current vehicle reaches the first target position.
The first power control parameters comprise an air compressor excess factor and an air compressor rotating speed parameter.
It should be understood that, since the power of the fuel cell system may be attenuated due to the oxygen content problem of the vehicle in the high altitude environment, the embodiment of the invention uses the VCU (Vehicle Control Unit, vehicle controller) to control the rotation speed of the air compressor in combination with the way of predicting the road condition function of the intelligent network system, so that the air excess factor of the vehicle is adjusted in advance according to the road condition in front of the vehicle just before entering the high altitude road, and the rotation speed of the air compressor is adjusted, so as to execute the power recovery of the fuel cell system.
As shown in fig. 3 and 2 (b), if the elevation value of the front road is greater than a first preset threshold value and there is a first target position, it is determined that the front road of the current vehicle is a high elevation climbing road, before the vehicle intelligent network system enters the high elevation climbing road, the elevation value and the gradient value (including the climbing gradient value, the climbing length value and the gradient angle value) of the front road and the distance to the climbing are predicted in advance, the Fuel cell system FCU (Fuel-cell Control Unit, the Fuel cell system controller) performs distribution power analysis according to the elevation value and the gradient value of the front road, the VCU corrects the current air excess coefficient and the current cooling coefficient according to the atmospheric pressure of the front road, and if the vehicle intelligent network system detects the change of the atmospheric pressure in real time, the elevation value continuously corrects the current air excess coefficient and the current cooling coefficient according to the atmospheric pressure and performs demand power analysis according to the current electric quantity of the power cell in advance.
When the current electric quantity of the power battery is smaller than the preset electric quantity, the fuel battery system analyzes the required power according to the elevation value, the gradient value (including a climbing gradient value, a climbing length value and a gradient angle value) and the distance to the climbing of the road, sends a rotating speed instruction of the air compressor to the air compressor, adjusts the rotating speed of the air compressor to a first rotating speed, and sends a BOP instruction according to the air flow of the road ahead, so that the fuel battery system can efficiently output power to charge the power battery before climbing, the SOC of the power battery is adjusted to an optimal climbing state, for example, the SOC of the power battery is adjusted to 95%, and when the vehicle enters the high-elevation climbing road, the vehicle is switched to a preset power request mode until the climbing is finished;
When the current electric quantity of the power battery is larger than or equal to the preset electric quantity, the fuel battery system analyzes the required power and calculates the distributed power according to the elevation value, the gradient value (including the climbing gradient value, the climbing length value and the gradient angle value) and the distance to the climbing of the front road, and issues a BOP instruction according to the air flow FCU of the front road, so that the power of the fuel battery system is used for charging the power battery before climbing, the SOC of the power battery is adjusted to the optimal climbing state, for example, the SOC of the power battery is adjusted to 95%, and when the vehicle enters the high-elevation climbing road, the vehicle is switched to a preset power request mode to travel until the climbing is finished.
The BOP instruction is an instruction that the fuel cell system sends a heat dissipation instruction, a pressure instruction and the like to devices such as an electronic water pump, a radiator, a hydrogen circulating pump and the like.
The first rotation speed and the preset electric quantity may be thresholds preset by a user, may be thresholds obtained through limited experiments, or may be thresholds obtained through limited computer simulation, and are not limited specifically herein.
In fig. 3, it should be noted that Nev _pack_soc is the power battery level; nev Ker P is the kinetic energy recovery power; FC_air_ec is the air excess factor; nev _high road elevation value Nev _ag_ldeg is downhill road; nev _high_f is a high altitude uphill road; nev _high_lr high altitude ordinary roads; FC_P_power is the power demand; nev _ag_deg is the predicted grade value; FC_BOP_ orde is a BOP command for the fuel cell system; FC_air_r is the Air compressor speed; nev _re_power is the power request; FC_Ap_ kap is atmospheric pressure; nev _high_h is the elevation continuously increasing; fc_hi_p high power output; fc_low_p Low power output; fc_power power output; nev _Ag_ Hdeg is climbing; nev _ag_ldeg is downhill, as shown in fig. 2 (b).
Optionally, in some embodiments, after determining whether the first target position with the gradient value greater than the second preset threshold exists, the method further includes: if the first target position does not exist, determining a second power control parameter of the fuel cell system according to the altitude value and the current electric quantity, and controlling the fuel cell system according to the second power control parameter; the air compressor excess coefficient in the second power control parameter is smaller than the air compressor excess coefficient in the first power control parameter, and the air compressor rotating speed in the second power control parameter is smaller than the air compressor rotating speed in the first power control parameter.
The second power control parameter also comprises an air compressor excess factor and an air compressor rotating speed parameter.
It should be understood that if the altitude value of the front road is greater than the first preset threshold value and there is no first target position with the gradient value greater than the second preset threshold value, it is determined that the front road is a high altitude common road, specifically as shown in fig. 4, the fuel cell system performs power distribution calculation in advance according to the altitude value of the front road, corrects the current air excess factor and the current cooling factor according to the atmospheric pressure of the front road, issues an air compressor rotation speed command to the air compressor, adjusts the air compressor rotation speed to the second rotation speed, and issues a BOP command to perform power output control for current vehicle driving. The second rotation speed may be a threshold preset by the user, may be a threshold obtained through limited experiments, or may be a threshold obtained through limited computer simulation, which is not limited herein.
It should be noted that, the air compressor excess coefficient under the high-altitude climbing road is larger than the air compressor excess coefficient under the high-altitude ordinary road, the air compressor rotation speed under the high-altitude climbing road is larger than the air compressor rotation speed under the high-altitude ordinary road, and the larger the air excess coefficient is, the larger the output power of the fuel cell system is.
Optionally, in some embodiments, after acquiring the current electric quantity of the current vehicle, the altitude value of the road ahead, and the gradient value, further includes: when the altitude value is smaller than or equal to a first preset threshold value and a first target position with the gradient value larger than a second preset threshold value exists, the fuel cell system is controlled according to the third power control parameter when the current electric quantity is larger than the preset electric quantity, and the fuel cell system is controlled according to the fourth power control parameter when the current electric quantity is smaller than or equal to the preset electric quantity; and switching the current vehicle to a preset power request mode when the current vehicle reaches the first target position.
The third power control parameter comprises an air compressor rotating speed parameter, and the fourth power control parameter also comprises the air compressor rotating speed parameter.
It should be appreciated that if the altitude value is less than or equal to the first preset threshold value and the first target position exists with the gradient value greater than the second preset threshold value, the road in front of the current vehicle is determined to be a low altitude uphill road, and when the current electric quantity of the power battery is less than or equal to the preset electric quantity, the fuel cell system also needs to charge the power battery in a power supply mode for the vehicle, so that the peak power output time of the fuel cell is easy to be longer, the service life of the fuel cell stack is reduced, and if the electric quantity of the power battery is too low, the torque is easy to be reduced, so that the vehicle is anchored.
Therefore, when the front road of the current vehicle is a low-altitude climbing road and the current electric quantity of the power battery is lower than the preset electric quantity, the intelligent network system predicts the gradient value (including the climbing gradient value, the climbing length value and the gradient angle value) of the front road and the distance to the climbing road in advance, as shown in fig. 5, the whole vehicle controller VCU analyzes the required power according to the climbing gradient length and the distance to the climbing road, issues an air compressor rotating speed command to adjust the air compressor rotating speed to a third rotating speed after the analysis is completed, issues other BOP commands according to the air flow, so that the power of the fuel battery system is efficiently output to charge the power battery, adjusts the SOC of the power battery to a higher climbing state before climbing, for example, adjusts the SOC of the power battery to 95%, and switches the vehicle to a preset power request mode until the climbing is completed when climbing starts.
When the front road of the current vehicle is a low-altitude climbing road and the current electric quantity of the power battery is larger than the preset electric quantity, the FCU analyzes the required power and calculates the distributed power according to the gradient value (including a climbing gradient value, a climbing length value and a gradient angle value) of the front road and the distance to the climbing road, then sends an air compressor rotating speed instruction to the air compressor to adjust the rotating speed to a fourth rotating speed, and enables the power of the fuel battery system to be high-efficiency output according to the received BOP instruction to charge the power battery, and adjusts the SOC of the power battery to a higher climbing state, such as adjusting the SOC of the power battery to 95%, and when the vehicle enters the climbing, the FCU is switched to a preset power request mode until the climbing is finished.
The third rotation speed and the fourth rotation speed may be thresholds set by the user in advance, may be thresholds obtained through limited experiments, or may be thresholds obtained through limited computer simulation, and are not particularly limited herein.
Optionally, in some embodiments, after acquiring the current electric quantity of the current vehicle, the altitude value of the road ahead, and the gradient value, further includes: if the gradient value is smaller than a third preset threshold value, determining a second target position of which the gradient value is smaller than the third preset threshold value, and judging whether the current electric quantity is larger than the preset electric quantity or not; and if the current electric quantity is larger than the preset electric quantity, reducing the output power of the fuel cell system to the preset power, and regulating the power cell system to an optimal kinetic energy recovery state so as to enter a kinetic energy recovery mode when the current vehicle reaches a second target position.
The second target position with the gradient value smaller than the third preset threshold value is the position of the downhill road.
The third preset threshold may be a threshold preset by a user, may be a threshold obtained through limited experiments, or may be a threshold obtained through limited computer simulation, which is not specifically limited herein.
It is understood that the road of the current vehicle in front of the downhill may be a high-altitude uphill road, or a high-altitude ordinary road, or a low-altitude uphill road, or a low-altitude ordinary road.
At present, when a fuel cell automobile is on a downhill and the SOC of a power cell is higher or reaches 100%, the kinetic energy recovery of the automobile is closed, so that a great amount of kinetic energy recovery is wasted, therefore, if the current automobile is on a low-altitude common road and the front road is a downhill road, as shown in fig. 5, the vehicle intelligent network system prediction function predicts the gradient value (comprising a downhill gradient value, a downhill length value and a gradient angle value) of the front downhill road in advance, and the VCU performs the kinetic energy recovery demand capacity analysis based on the gradient value; if the current vehicle is still on a high-altitude climbing road, a high-altitude ordinary road or a low-altitude climbing road, and the front road is a downhill road, the climbing ending distance and the altitude value are also required to be predicted, the VCU performs the kinetic energy recovery demand capacity analysis based on the altitude value, the gradient value and the climbing ending distance, and corrects the current air excess coefficient according to the atmospheric pressure of the front road.
Further, the fuel cell system analyzes the required power in advance according to the current electric quantity of the power cell, when the current electric quantity of the power cell is larger than the preset electric quantity, the fuel cell system issues an air compressor rotating speed instruction to adjust the rotating speed of the air compressor to a fourth rotating speed, other BOP instructions are issued at the same time, the output power is reduced to the preset power, the power cell system is adjusted to a maximum kinetic energy recovery mode, and the maximum kinetic energy recovery mode is entered when the current vehicle enters a downhill road.
Optionally, in some embodiments, after determining whether the current power is greater than the preset power, the method further includes: and if the current electric quantity is smaller than or equal to the preset electric quantity, controlling the current vehicle to be in a preset power request mode, and entering a kinetic energy recovery mode when the current vehicle reaches a second target position.
It will be appreciated that when the road ahead of the current vehicle is a downhill road and the current charge of the power battery is less than or equal to the preset charge, the fuel cell system controls the current vehicle to enter a preset power request mode and adjusts the power battery system to an optimal kinetic energy recovery state and enters a maximum kinetic energy recovery mode when the current vehicle reaches the downhill road.

Therefore, the vehicle is provided with the power control parameter of the fuel cell system, the power control parameter of the fuel cell system is adjusted before entering the front road, so that the vehicle keeps an optimal running state, the problems that the fuel cell system lacks a working condition prediction function, the vehicle adopts a power request mode under a continuous climbing on a plateau, the continuous peak power output easily causes the thermal management failure of the vehicle and even stops, and the service life of the fuel cell stack is reduced are solved, the power of the fuel cell system is efficiently output, the peak power output time of the fuel cell system is reduced, the service life of the fuel cell stack is prolonged, and the vehicle is ensured not to stop due to insufficient electric quantity of the power cell system under the continuous climbing or complex working conditions.
