Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the existing gear control method, when a vehicle runs, a gear shifting actuating mechanism executes gear shifting action according to the opening degree of an accelerator (a fuel vehicle) or the voltage (a new energy vehicle). Due to the fact that the self-loading state cannot be identified, when the commercial vehicle is in an empty state or in a full state, the commercial vehicle can run in the first gear and can also run in the second gear. Unnecessary energy waste is caused when the vehicle runs in a first gear with no load and a second gear with full load.
However, since the vehicle is loaded differently and is suitable for different gears, the above-mentioned manner may cause that the vehicle is started in the first gear when the vehicle is unloaded or in the second gear when the vehicle is fully loaded, which results in low vehicle starting efficiency and unnecessary energy waste.
Based on this, the starting system of the new energy vehicle and the new energy vehicle provided by the embodiment of the invention can be applied to starting scenes of various new energy vehicles.
For the convenience of understanding the embodiment, a detailed description will be given to a starting system of a new energy vehicle disclosed in the embodiment of the present invention.
The embodiment of the invention provides a starting system of a new energy vehicle. As shown in fig. 1, the system includes a weight sensor 10, a controller 20, and a driving motor 30; the controller 20 is connected to the weight sensor 10 and the driving motor 30, respectively. Correspondingly, a starting method of the new energy vehicle can be realized based on the system, and the method is mainly applied to a controller in the system. As shown in fig. 2, the method comprises the steps of:
and step S100, acquiring the load parameters of the new energy vehicle.
Specifically, the load parameter may be detected by a weight sensor. The load parameter may include the self load of the new energy vehicle, or may only include the load of the new energy vehicle to the cargo.
And step S102, determining a starting gear of the new energy vehicle based on the load parameter.
Specifically, the load condition of the new energy vehicle can be obtained by comparing the load parameter with a preset weight threshold; and determining a starting gear of the new energy vehicle based on the load condition. The controller can comprise a load information processing module and a vehicle control unit; the load information processing module is used for the comparison process, and the vehicle control unit is used for determining the starting gear.
In general, the load condition of the vehicle may be empty, half loaded or full loaded. In order to determine the load condition of the vehicle, a first threshold value and a second threshold value may be set as the weight threshold value, wherein the second threshold value is greater than the first threshold value. When the load condition is determined, whether the load parameter is smaller than a preset first threshold value or not can be judged firstly; if the load condition is smaller than the first threshold value, determining that the load condition of the new energy vehicle is no load; if the load parameter is larger than or equal to the first threshold, judging whether the load parameter is smaller than a preset second threshold; if the load condition is smaller than the second threshold value, determining that the load condition of the new energy vehicle is half load; and if the load condition is larger than or equal to the second threshold value, determining that the new energy vehicle is fully loaded.
Corresponding to the above processing procedure, the load information processing module may be provided with a first comparing unit and a second comparing unit; the first comparison unit is used for judging the load parameters and the first threshold value; the second comparing unit is used for judging the load parameter and the second threshold value.
In the process of determining the starting gear through the vehicle control unit, when the load condition is no-load, determining that the starting gear of the new energy vehicle is in the second gear; and when the load condition is half load or full load, determining the starting gear of the new energy vehicle as the first gear. When the first gear is started, the torque is large, and the vehicle needs large torque to drive the vehicle to start under the condition of half load or full load, so that when the load condition is half load or full load, the first gear is used as a starting gear. And when the vehicle is unloaded, a larger torque is not needed, and the torque of the second gear is smaller, so that when the load condition is half load or full load, the second gear is adopted as a starting gear.
And step S104, controlling the driving motor to work based on the starting gear so as to drive the new energy vehicle to start.
When the starting gears are different, the torque of the vehicle is different, the motor efficiency distribution conditions of the driving motor under different rotating speeds and torques are also different, and a corresponding motor MAP, namely a motor ignition control curve chart, is provided. When the starting gear is a first gear, a pre-acquired motor ignition control curve graph corresponding to the first gear can be called to determine the working frequency of the driving motor; when the starting gear is the second gear, calling a pre-acquired motor ignition control curve graph corresponding to the second gear, and determining the working frequency of the driving motor; and controlling the driving motor to work at the determined working frequency.
In a specific implementation, the system further comprises a gear shifting actuating mechanism; the controller is connected with the gear shifting actuating mechanism; the controller is further used for sending a control instruction to the gear shifting executing mechanism after the starting gear is determined, so that the gear shifting executing mechanism can switch the gear of the new energy vehicle to the starting gear.
The embodiment of the invention provides a starting method of a new energy vehicle, which comprises the steps of obtaining load parameters of the new energy vehicle, determining a starting gear of the new energy vehicle based on the load parameters, and controlling a driving motor to work based on the starting gear so as to drive the new energy vehicle to start. According to the method, the load parameters are obtained, and the gear suitable for starting is determined according to the load parameters, so that the starting efficiency of the new energy vehicle is improved, and the energy is saved.
Typically, the system further comprises a motor controller; the controller is connected with the driving motor through the motor controller; the controller is also used for sending an instruction to the motor controller based on the starting gear so that the motor controller controls the driving motor to work.
Further, the system can also comprise a communication module; the vehicle load sensor sends the load parameters to the controller through the communication module. The communication module may include a CAN bus.
Corresponding to the starting method of the new energy vehicle, the embodiment of the invention also provides a starting device of the new energy vehicle, which is arranged on a controller of the new energy vehicle; the controller is connected with the driving motor; as shown in fig. 3, the apparatus includes the following modules:
the parameter acquiring module 300 is used for acquiring the load parameters of the new energy vehicle;

The invention further provides a starting system of the new energy automobile. When the system works, the vehicle runs in the most reasonable energy consumption interval by respectively controlling the motor running mode and the first-gear and second-gear state. Therefore, the useless consumption of energy can be controlled to the maximum extent, and the service life of the power supply can be prolonged.
The system consists of three parts, namely an information acquisition part, a central processing system and an operation part, as shown in figure 4.
The working principle of the system is as follows:
firstly, vehicle load information is collected through an information collection part; then, optimizing by using a central processing system, and distinguishing whether the vehicle is in a no-load state, a half-load state and a full-load state; and finally, a first-gear driving instruction or a second-gear driving instruction is given by combining the motor Map, so that the vehicle can be started at a reasonable gear.
Wherein, the information acquisition part comprises a vehicle load sensor; the central processing system (equivalent to the controller) comprises a communication module, a load information processing module, a vehicle control unit and a motor control part; the operation part includes a driving motor.
The system control method is as follows:
when the new energy vehicle is in a parking state, the load information is transmitted to the load information processing module through the vehicle load sensor in the information acquisition part by the communication module. The load information processing module discriminates whether the vehicle is in an empty, half-loaded, or full state based on the load information. At the moment, the vehicle controller sends different torque control instructions of the motor according to the three states and by combining different motor MAP, so that the motor operates in a corresponding large-current large-torque mode under the full-load and half-load states; operating in a lower torque mode under no load conditions. Meanwhile, the vehicle controller outputs a first-gear driving instruction or a second-gear driving instruction according to the no-load, half-load and full-load states and by combining the motor operation state, so that the whole vehicle operates in an optimal energy consumption interval.
