Detailed Description
The inventor finds that in the torque output control of the current pure electric vehicle, the magnitude of the control output torque is generally closely related to the opening degree of an accelerator, for example, the output torque of a power system with a small opening degree of the accelerator is relatively small, the output torque of the power system with a large opening degree of the accelerator is relatively large, and the maximum output torque of the power system is maximum when the opening degree of the accelerator is maximum.
Such a control method is highly disadvantageous when the vehicle is in mountainous terrain or steep-slope terrain. For example, if the throttle of the vehicle is fully opened on a straight road section or a road section with a small slope, the motor has more chances to work in the maximum torque section, and the probability of overheating of the motor is higher, because the sustainable time of the motor in the maximum working section is shorter, generally 30 to 60 seconds, and the motor is in the maximum torque output working condition, the motor is easily overheated. And when the vehicle needs to climb before really reaching the steep slope, the temperature of the motor can be high, and the faced steep slope can not climb up.
In order to improve the adaptability of the vehicle power system to the environment, the motor of the vehicle power system adopting the torque output control method is usually configured to be higher, and the maximum torque and the continuous torque of the motor are both higher, so that the cost of the motor is increased, the vehicle weight is increased, and the energy consumption of the vehicle is poor.
Based on this, referring to fig. 1, fig. 1 is a schematic flow chart of a data processing method of output torque according to an embodiment of the present invention, specifically, the data processing method includes the steps of:
s11, road spectrum information of a to-be-driven route of the target new energy vehicle is obtained.
The road spectrum information comprises GPS information and gradient information of each position point.
And S12, acquiring the current running position point and running direction of the target new energy vehicle.
And S13, acquiring temperature information of the target new energy vehicle.
Wherein the temperature information at least comprises one or more of a motor temperature and a power battery temperature.
And S14, determining the target output torque of the target new energy vehicle based on the temperature information, the current driving position point, the driving direction and the road spectrum information.
In the embodiment, the information of the GPS position, the gradient and the like at each position in the running route is input into the memory of the control system through the pre-collected road spectrum information of the fixed route on which the pure electric vehicle runs. When the vehicle runs at different positions of a fixed line, the vehicle position and the running direction are determined according to the GPS signals, and the output of the vehicle torque is controlled by combining a motor temperature signal, a power battery temperature signal and the like.
For example, if the temperature of the motor is low when the vehicle is determined to be on a flat road or a road with a small slope based on the GPS signal, the control system will set the output torque of the powertrain to a large value, but not too large, and it is necessary to keep the temperature of the motor below a certain value to ensure that the vehicle has a sufficient temperature reserve (over-temperature reserve) to complete the climbing task before a steep slope in the forward direction.
For another example, if the vehicle is judged to be on a flat road or a road with a small gradient and the temperature of the motor is high according to the GPS signal, the control system sets the output torque of the power system to a small value so as to ensure that the vehicle has enough temperature reserve (overheat capacity reserve) to complete the climbing task before a steep slope in the advancing direction.
For another example, when the vehicle is judged to be in front of a steep slope or climbing a steep slope according to the GPS signal, if the accelerator opening degree is maximum, the control system sets the maximum torque output by the power system to be the maximum value, and the vehicle is used for completing a climbing task.
Therefore, the target output torque output by the scheme is combined with GPS information, gradient information and temperature information, and tasks such as climbing and the like are realized by motor configuration with lower cost.
Specifically, as shown in fig. 2, an embodiment of the present invention provides a specific implementation manner for determining a target output torque of the target new energy vehicle based on the temperature information, the current driving position point, the driving direction, and the road spectrum information, including:
s21, determining target gradient information of the target new energy vehicle based on the current driving position point, the driving direction and the road spectrum information;
and S22, determining the target output torque of the target new energy vehicle based on the target gradient information and the temperature information.
Wherein, the step S21 can be obtained by a method as shown in fig. 3, and includes the steps of:
s31, determining the current GPS information of the target new energy vehicle based on the current driving position point and the road spectrum information;
and S32, determining the target gradient information of the road where the target new energy vehicle is located based on the GPS information and the driving direction.
The step S22 may be obtained in a manner as shown in fig. 4, and includes the steps of:
s41, when the target gradient information is smaller than a first preset gradient and the temperature information is smaller than a first preset temperature, determining a first output torque as a target output torque of the target new energy vehicle;
s42, when the target gradient information is smaller than a first preset gradient and the temperature information is larger than a second preset temperature, determining a second output torque as a target output torque of the target new energy vehicle;
s43, when the target gradient information is larger than a second preset gradient, determining a third output torque as a target output torque of the target new energy vehicle; the second preset temperature is greater than the first preset temperature, the third output torque is greater than the first output torque, the first output torque is greater than the second output torque, and the second preset gradient is greater than the first preset gradient.
Fig. 5, with reference to fig. 5, is a schematic structural diagram of a data processing system according to an embodiment of the present invention, and illustrates an operating principle of the foregoing embodiment, as follows:
the data processing system includes a GPS module 51, a throttle position sensor 52, a motor controller 53, a control signal collector 54, and a motor torque output controller 55.
Wherein, GPS information, an accelerator position sensor signal, a temperature sensor signal of a driving motor (comprising a motor body and a temperature sensor signal on a motor controller) and other control input signals (such as a power battery temperature sensor signal, an air compressor system working state signal, a steering system working state signal and the like) are input into the torque output controller.
The memory of the torque output controller is provided with road spectrum data information of a vehicle running road collected in advance, wherein the road spectrum data information comprises GPS data information of each position in the vehicle running road. The input GPS information is compared with the GPS information stored in a memory in the controller, the current position and the advancing direction of the vehicle can be judged according to the value and the variation trend of the GPS information, and then the controller determines the output torque value of the motor and controls the working temperature state of the parts of the power system by combining the accelerator opening, the input motor temperature, the power battery temperature signal and other control input signal source information, so that the power system has enough overheat capacity to store steep slope road conditions to appear on the line in the running process of the vehicle, and simultaneously, the energy consumption of the system is optimized.
If the vehicle is judged to be running on a straight road or a road with a small gradient according to the GPS signal, if the temperatures of the motor and the power battery are low and other control input signals have no limit to the maximum torque output of the motor, if the accelerator full-open control system sets the maximum output torque of the power system to be a large value but not too large, the temperatures of the motor and the power battery are required to be lower than a certain value so as to ensure that the vehicle has enough overheat capacity to reserve before a steep slope in the advancing direction and complete a climbing task.
If the vehicle is judged to be on a flat road or a road with a small gradient and the temperature of the motor or the power battery is high according to the GPS signal, if the accelerator full-open control system sets the maximum output torque of the power system to be a small value, enough overheating capacity storage of the vehicle before a steep slope in the advancing direction is ensured, and the climbing task is completed.
If the vehicle is judged to be in front of a steep slope or climbing the steep slope according to the GPS signal, if the opening degree of the accelerator is maximum, the control system sets the maximum torque which can be output by the power system to be the maximum value, and the vehicle is used for finishing a climbing task.
Besides, the relation between the output torque of the power system and the opening degree of an accelerator, the temperature of a motor, the temperature of a power battery and other limiting factors can be solidified through a calibration table, and the optimal value is finally determined through repeated tests, so that the torque output of the power system can ensure that the vehicle can smoothly run and the energy consumption is optimized at the same time.
The final value of the torque output of the control system is transmitted to the motor controller through a bus and the like, and the motor controller is controlled through the bus, so that the actual torque output of the power system is controlled.
