Specifically, part load dynamics: the driver's feeling of dynamics when stepping on any accelerator pedal stroke. In-situ starting dynamics: when the vehicle is stationary, the driver's feeling of dynamics by stepping on any accelerator pedal stroke. Part load re-acceleration dynamics: and when the vehicle runs at a constant speed and then presses a certain accelerator pedal stroke increment, the driver feels power. Acceleration gain: the acceleration of the vehicle can be obtained by stepping on the stroke of the accelerator pedal every millimeter when the vehicle runs at a constant speed.
In this embodiment, a performance analysis type to be tested, a test mode and test parameters are obtained, the performance analysis type includes acceleration dynamic property and uniform running dynamic property, the test mode is a test method flow of each performance analysis type, and different types of performance analyses are performed, and corresponding test modes are different. The test parameters are parameter indexes which are needed to be achieved by the control vehicle in each test process, and are mainly used for controlling the vehicle to be evaluated to execute corresponding performance evaluation tests respectively.
And when the performance analysis type is detected to be acceleration dynamic performance, the performance of the vehicle in the acceleration process is evaluated, so that the vehicle to be evaluated is controlled to start accelerating according to the test mode and the test parameters until the vehicle to be evaluated reaches a certain speed and runs at a constant speed. And collecting peak acceleration of the vehicle to be evaluated in the acceleration process of accelerating to a certain vehicle speed, and acquiring the acceleration dynamic property of the vehicle to be evaluated according to the test parameters and the peak acceleration.
When the performance analysis type is detected to be uniform running dynamic performance, namely, the performance of the vehicle in the uniform running process is evaluated, the vehicle to be evaluated is controlled to achieve the target uniform speed and uniformly run according to the test mode, and the uniform accelerator pedal travel of the vehicle to be evaluated in the uniform running state is acquired, wherein the test parameters comprise the target uniform speed. And then, obtaining the constant-speed driving dynamics of the vehicle to be evaluated based on the target constant-speed according to the constant-speed accelerator pedal stroke.
The invention identifies the performance category to be evaluated through the performance analysis type, and then executes corresponding performance test according to the test parameters so as to objectively evaluate the dynamic performance of the vehicle. Meanwhile, the vehicle dynamic performance is evaluated based on the partial load of the vehicle, rather than the limit dynamic performance which can be achieved by the vehicle when the opening degree of the accelerator pedal is 100%, and the actual driving working condition of the driver can be attached to the vehicle, so that the daily actual driving feeling is well reflected.
Optionally, in another embodiment of the present invention, when the performance analysis type is detected as acceleration dynamics, step S200 controls the vehicle to be evaluated to start accelerating according to the test mode and the test parameter until the vehicle to be evaluated reaches a certain vehicle speed and uniformly travels, including the following steps:
The acceleration dynamics include a start acceleration dynamics and a re-acceleration dynamics;
s220, when the performance analysis type is detected to be starting acceleration dynamic, controlling a vehicle to be evaluated to accelerate from rest to a certain vehicle speed at a constant speed according to a starting accelerator pedal stroke, wherein the test parameters comprise the starting accelerator pedal stroke;
s230, when the performance analysis type is detected to be the re-acceleration dynamic property, controlling the vehicle to be evaluated to keep the re-acceleration starting vehicle speed to run at a constant speed, wherein the test parameters comprise the re-acceleration starting vehicle speed and an accelerator pedal stroke increment;
s240, controlling the vehicle to be evaluated to accelerate according to the increment of the travel of the accelerator pedal until the vehicle to be evaluated reaches a certain speed and runs at a constant speed.
Specifically, in the present embodiment, the acceleration dynamics of the vehicle include a start dynamics of starting acceleration from rest and a re-acceleration dynamics of starting acceleration from a certain speed, which are different depending on the state before the vehicle starts accelerating. In this case, the vehicle is ultimately in a part-load state, i.e. the accelerator pedal travel is not 100%.
When the performance analysis type is detected to be starting acceleration dynamic, controlling the vehicle to be evaluated to start accelerating from static according to a starting accelerator pedal stroke under a starting gear, namely keeping the accelerator pedal stroke constant under the starting accelerator pedal stroke until the vehicle to be evaluated reaches a certain vehicle speed and runs at a constant speed, wherein the test parameters comprise the starting accelerator pedal stroke. The vehicle to be evaluated is not constant due to the change of different factors during the test, such as the change of the environmental state of the vehicle to be evaluated, and the purpose of controlling the vehicle to be evaluated to start accelerating is to collect data in the accelerating process subsequently, so that when the vehicle to be evaluated is detected to accelerate to a certain vehicle speed and the certain vehicle speed is kept constant for more than a preset time period, the vehicle to be evaluated is judged to reach a constant-speed running state.
The accelerator pedal stroke CAN be obtained by converting an accelerator pedal opening signal which CAN be read by the vehicle CAN, and the actual pedal stroke CAN be obtained by multiplying the pedal opening by the effective total stroke and adding the idle stroke, and CAN also be directly obtained by adding a displacement sensor. During testing, if an accelerator pedal position signal is obtained through vehicle CAN information, the selection of a typical working point is still measured by the accelerator pedal opening degree, and then the accelerator pedal stroke which is more suitable for being used as a comparison standard is converted, so that the free conversion between the accelerator pedal stroke and the accelerator pedal opening degree CAN be realized.
The starting peak acceleration corresponding to the strokes of the plurality of starting accelerator pedals of the same vehicle to be evaluated is obtained, and as shown in fig. 2, the starting accelerator pedal strokes are taken as horizontal axes, and the starting peak acceleration is taken as vertical axes, so that the starting acceleration dynamic property of the vehicle to be evaluated under different starting accelerator pedal strokes can be more intuitively known. If the corresponding starting peak acceleration under a certain starting accelerator pedal stroke is larger than the corresponding starting peak acceleration under another starting accelerator pedal stroke, the starting acceleration dynamic property of the vehicle to be evaluated on one starting accelerator pedal stroke with larger starting peak acceleration is judged to be stronger. Further, the starting peak acceleration values corresponding to the starting accelerator pedal strokes of the vehicles to be evaluated can be plotted in a unified table, such as the vehicle model 1 and the vehicle model 2 in fig. 2, so that the starting acceleration dynamics of the vehicles to be evaluated under the same starting accelerator pedal stroke can be more intuitively understood, and the acceleration dynamics of the vehicles to be evaluated need to be limited to the same starting accelerator pedal stroke.
In addition, target peak acceleration corresponding to the travel of the multiple vehicles to be evaluated on different target starting accelerator pedal is obtained, starting acceleration gain is calculated according to the travel of the target starting accelerator pedal and the corresponding target peak acceleration, and then starting acceleration dynamic property is evaluated according to the starting acceleration gain. Wherein, according to the target starting accelerator pedal stroke s 1 And target peak acceleration a 1 Calculating a start acceleration gain Deltaa when a unit start accelerator pedal stroke 1 ，
Drawing a table by taking a target starting accelerator pedal stroke as a horizontal axis and a starting acceleration gain as a vertical axis, and drawing starting acceleration gains respectively corresponding to a plurality of starting accelerator pedal strokes of a plurality of different vehicles to be evaluated in a unified table, such as a vehicle model 1 and a vehicle model 2 shown in fig. 3, so as to be capable of more intuitively knowing the starting acceleration dynamics of different vehicles to be evaluated under different starting accelerator pedal strokes. Under the same starting accelerator pedal stroke, if the corresponding starting acceleration of a certain vehicle to be evaluatedAnd if the gain is larger than the corresponding starting acceleration gain under the other vehicle to be evaluated, judging that the starting acceleration dynamic property of the vehicle to be evaluated with larger starting acceleration gain is stronger. The acceleration dynamics of different vehicles to be evaluated are evaluated, and the same starting accelerator pedal stroke is required to be limited.
When the performance analysis type is detected to be the re-acceleration power performance, firstly controlling the vehicle to be evaluated to reach the re-acceleration starting speed, and then controlling the vehicle to be evaluated to accelerate from the re-acceleration starting speed according to the test parameters until the vehicle to be evaluated reaches a certain speed and runs at a constant speed. The test parameters comprise a re-acceleration starting vehicle speed and a re-acceleration pedal stroke increment, and for the same vehicle to be evaluated, acceleration is carried out based on different re-acceleration starting vehicle speeds, and corresponding re-acceleration dynamics are different. The vehicle to be evaluated is controlled to be kept at the re-acceleration starting speed, wherein the vehicle to be evaluated can be directly accelerated to the re-acceleration starting speed from a static vehicle speed or a lower vehicle speed (for example, the preset vehicle speed is reduced on the basis of the re-acceleration starting speed), or can be decelerated to the re-acceleration starting speed after being accelerated to a higher vehicle speed (for example, the preset vehicle speed is increased on the basis of the re-acceleration starting speed), and then the re-acceleration starting speed is kept to be driven at a constant speed.
And when the vehicle to be evaluated keeps the re-acceleration starting vehicle speed to run at a constant speed, controlling the vehicle to be evaluated to accelerate according to the re-acceleration pedal stroke increment, namely, re-pressing the pedal stroke corresponding to the re-acceleration pedal stroke increment. After the pedal stroke corresponding to the travel increment of the re-accelerator pedal is stepped on again for a period of time, namely, the travel of the accelerator pedal is kept constant as the sum of the original travel maintaining the constant speed of the vehicle and the travel increment of the re-accelerator pedal, the vehicle to be evaluated gradually tends to travel at a constant speed, namely, the vehicle to be evaluated reaches a certain speed and travels at a constant speed.
Collecting peak acceleration of the vehicle to be evaluated in the acceleration process from the re-acceleration starting vehicle speed to a certain vehicle speed, calculating re-acceleration gain delta a when the unit re-acceleration pedal stroke is calculated according to the re-acceleration pedal stroke increment s and the peak acceleration a in the acceleration process from the re-acceleration starting vehicle speed to the certain vehicle speed,
and acquiring the reacceleration dynamic property of the vehicle to be evaluated based on the reacceleration pedal stroke increment according to the acceleration gain. The larger the re-acceleration gain is, the better the re-acceleration dynamic property of the vehicle to be evaluated is. Further, for the same vehicle to be evaluated, it is necessary to evaluate the reacceleration dynamics at different reacceleration start vehicle speeds based on the same reacceleration pedal stroke increment. For different vehicles to be evaluated, the re-acceleration dynamics of the vehicles need to be evaluated based on the same re-acceleration pedal stroke increment and the same re-acceleration starting vehicle speed.
According to the invention, the re-acceleration dynamic property of the vehicle to be evaluated is judged through the re-acceleration gain when the travel increment of the re-acceleration pedal is performed, pedal parameters (such as the corresponding relation between the pedal opening and the pedal travel) of each vehicle to be evaluated do not need to be considered, the problem that a driver needs to convert the pedal travel of stepping down into the accelerator opening and the problem that the comparison standard is not uniform is avoided, so that the evaluation standard is more uniform, and the vehicles to be evaluated are convenient to compare mutually.
In addition, under the same travel increment of the re-acceleration pedal, the re-acceleration gain corresponding to the vehicle to be evaluated under a plurality of re-acceleration initial vehicle speeds can be obtained, then according to the plurality of re-acceleration initial vehicle speeds and the re-acceleration gain corresponding to the plurality of re-acceleration initial vehicle speeds, the re-acceleration initial vehicle speed is taken as a horizontal axis, the re-acceleration gain is taken as a vertical axis, and a visual chart of the relation between the re-acceleration initial vehicle speed and the re-acceleration initial vehicle speed is drawn, as shown in fig. 4. If the corresponding re-acceleration gain of a certain re-acceleration starting vehicle speed is larger than the corresponding re-acceleration gain of another re-acceleration starting vehicle speed, judging that the re-acceleration dynamic property of the vehicle to be evaluated under the increment of the travel of the re-acceleration pedal at the certain re-acceleration starting vehicle speed is stronger than that at the other re-acceleration starting vehicle speed. In addition, based on the same travel increment of the re-acceleration pedal, the re-acceleration starting speed is taken as a horizontal axis, the re-acceleration gain is taken as a vertical axis, and the re-acceleration gains of different vehicles to be evaluated under the respective re-acceleration starting speeds can be respectively plotted as a visual chart of the re-acceleration starting speed and the re-acceleration gain in association, so that the re-acceleration dynamics between the vehicles to be evaluated can be visually and quantitatively checked and compared.
The starting acceleration dynamics can also be evaluated according to the re-acceleration peak acceleration. As shown in fig. 6, under the same accelerator pedal stroke increment, the re-acceleration starting vehicle speed is plotted on the horizontal axis, and the re-acceleration peak acceleration is plotted on the vertical axis, so that the partial load re-acceleration dynamics of the vehicle to be evaluated at different re-acceleration starting vehicle speeds can be more intuitively understood. If the corresponding re-acceleration peak acceleration of one re-acceleration starting vehicle speed is larger than the corresponding re-acceleration peak acceleration of the other re-acceleration starting vehicle speed, the re-acceleration dynamic property of the vehicle to be evaluated at the one re-acceleration starting vehicle speed with the larger re-acceleration peak acceleration is judged to be stronger. Further, the re-acceleration peak accelerations corresponding to the same accelerator pedal stroke increment and the re-acceleration starting vehicle speeds of the plurality of different vehicles to be evaluated can be plotted in the same table, as in the vehicle model 1 and the vehicle model 2 shown in fig. 5, so that the re-acceleration dynamics of the different vehicles to be evaluated under the same accelerator pedal stroke increment and the different re-acceleration starting vehicle speeds can be more intuitively understood.
Optionally, as shown in fig. 6, in another embodiment of the present invention, the step of "S300 collecting a peak acceleration during acceleration of the vehicle to be evaluated to the certain vehicle speed and obtaining acceleration dynamics of the vehicle to be evaluated according to the test parameter and the peak acceleration" includes the following steps:
S310, collecting all acceleration data in the acceleration process of accelerating the vehicle to be evaluated to a certain vehicle speed;
s320, selecting the maximum acceleration in all the acceleration data as the peak acceleration;
s330, acquiring the acceleration dynamic property of the vehicle to be evaluated according to the test parameters and the peak acceleration.
Specifically, in this embodiment, all acceleration data during acceleration of the vehicle to be evaluated to a certain vehicle speed is collected, where the acceleration process is a process of starting acceleration from rest to a certain vehicle speed or a process of starting acceleration from a re-acceleration to a certain vehicle speed. And selecting the maximum acceleration in all acceleration data as peak acceleration, wherein the starting acceleration dynamic property corresponds to the starting peak acceleration, the re-acceleration dynamic property corresponds to the re-acceleration peak acceleration, and acquiring the acceleration dynamic property of the vehicle to be evaluated according to the test parameters and the peak acceleration.
Optionally, in another embodiment of the present invention, when the performance analysis type is detected as the constant speed driving dynamics, the step S400 controls the vehicle to be evaluated to reach a target constant speed vehicle speed and constant speed driving according to the test mode, and collects a constant speed accelerator pedal stroke of the vehicle to be evaluated in a constant speed driving state, where the test parameter includes the target constant speed vehicle speed, and includes the following steps:
S410, when the performance analysis type is detected to be uniform-speed running dynamic, controlling the vehicle to be evaluated to accelerate from a first preset vehicle speed to the target uniform-speed vehicle speed, and controlling the vehicle to be evaluated to keep the target uniform-speed vehicle speed to run at a uniform speed, or controlling the vehicle to be evaluated to keep the target uniform-speed vehicle speed to run at a uniform speed; controlling the vehicle to be evaluated to accelerate to a second preset vehicle speed, and then decelerating from the second preset vehicle speed to the target constant speed for constant speed running, wherein the test parameters comprise the target constant speed;
s420, collecting a uniform accelerator pedal stroke of the vehicle to be evaluated in the target uniform speed running state.
Specifically, in this embodiment, when it is detected that the performance analysis type is the constant speed driving dynamics, that is, the performance of the vehicle in the constant speed driving state is evaluated, the vehicle to be evaluated is controlled to be driven at the target constant speed vehicle speed based on the obtained target constant speed vehicle speed. The vehicle to be evaluated may be directly accelerated to the target constant speed from a first preset vehicle speed, where the first preset vehicle speed is a stationary or lower vehicle speed (for example, the preset vehicle speed is reduced based on the target constant speed), or may be accelerated to a second preset vehicle speed and then decelerated to the target constant speed, where the second preset vehicle speed is a higher vehicle speed (for example, the preset vehicle speed is increased based on the target constant speed), and then the target constant speed is kept for constant speed running. And acquiring a uniform accelerator pedal stroke of the vehicle to be evaluated in a uniform running state, namely a minimum accelerator pedal stroke of the vehicle to be evaluated in a uniform running state at a target uniform speed, and acquiring uniform running dynamic property of the vehicle to be evaluated based on the target uniform speed according to the uniform accelerator pedal stroke.
For evaluation test of uniform driving dynamics, the manual gear vehicle and the automatic gear vehicle have different gear switching modes, and the manual gear vehicle selects different gears and has different corresponding acceleration modes, so that the control modes of the manual gear vehicle and the automatic gear vehicle are different.
If the vehicle to be evaluated is detected to be a manual gear vehicle, a current test gear to be tested is obtained, the vehicle to be evaluated is controlled to accelerate to a target vehicle speed under the test gear, then the vehicle speed is reduced to a target constant speed for running, and a constant speed accelerator pedal stroke of the vehicle to be evaluated in a constant speed running state is collected. In each gear, the acceleration mode of the manual transmission vehicle is fixed, so that the uniform speed accelerator pedal stroke corresponds to the target uniform speed.
And if the vehicle to be evaluated is detected to be an automatic gear vehicle, controlling the vehicle to be evaluated to accelerate to a target vehicle speed, and then reducing the vehicle speed to a target constant speed for running. For an automatic transmission vehicle, when the gear switching fluctuation is in, a plurality of uniform speed accelerator pedal strokes correspond to the same target uniform speed. For the same target constant speed vehicle speed, when the automatic transmission vehicle is in a high gear, the corresponding constant speed accelerator pedal stroke is smaller, and when the automatic transmission vehicle is in a low gear, the corresponding constant speed accelerator pedal stroke is larger, so that the target constant speed vehicle speed is reduced from a higher speed, namely the target vehicle speed, so that the constant speed accelerator pedal stroke of the vehicle to be evaluated in a constant speed running state in the higher gear, namely the minimum constant speed accelerator pedal stroke corresponding to the target constant speed vehicle speed, is acquired. The vehicle speed difference between the target vehicle speed and the target constant speed is not particularly limited.
According to the invention, the vehicle to be evaluated is accelerated to the target vehicle speed, and then the vehicle speed is reduced to the target constant speed for running, so that the collected constant speed accelerator pedal travel corresponding to the target constant speed when the vehicle to be evaluated is in a high gear, namely the minimum constant speed accelerator pedal travel, is ensured, and the constant speed running dynamic property of the vehicle to be evaluated can be expressed.
The constant-speed accelerator pedal travel corresponding to the plurality of target constant-speed speeds of the same vehicle to be evaluated is obtained, and as shown in fig. 7, the target constant-speed is taken as a horizontal axis, and the constant-speed accelerator pedal travel is taken as a vertical axis to draw a table, so that the constant-speed running dynamics of the vehicle to be evaluated at different target constant-speed speeds can be more intuitively known. If the corresponding constant speed accelerator pedal travel under a certain target constant speed is smaller than the corresponding constant speed accelerator pedal travel under another target constant speed, the constant speed running dynamic property of the vehicle to be evaluated under the target constant speed with smaller constant speed accelerator pedal travel is judged to be stronger.
Further, the uniform accelerator pedal strokes corresponding to the target uniform speed of the vehicles to be evaluated can be plotted in a unified table, such as the vehicle model 1 and the vehicle model 2 in fig. 7, so that uniform speed running dynamics of the vehicles to be evaluated under the same target uniform speed can be more intuitively known, and uniform speed running dynamics of the vehicles to be evaluated can be evaluated, and the uniform speed running dynamics of the vehicles to be evaluated need to be limited to the same target uniform speed. In addition, when the vehicle to be evaluated is a manual transmission vehicle, the same test gear should be defined.
