Detailed Description
The core of the invention is to provide a control method for energy consumption test by a working condition method, which reduces the labor cost and has higher accuracy of speed control, and the method can control the speed of the vehicle to be tested after ensuring that the vehicle meets the test conditions, thus being beneficial to improving the safety and accuracy of the energy consumption test; the other core of the invention is to provide the control device for the energy consumption test by the working condition method, which reduces the labor cost and has higher accuracy of speed control.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious 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.
Referring to fig. 1, fig. 1 is a schematic flow chart of a control method for energy consumption testing by a working condition method according to the present invention, including:
step S1: judging whether the vehicle state of the vehicle to be tested meets the test condition or not;
specifically, when the energy consumption test is performed on the vehicle to be tested, some basic test conditions, such as normal rotation of wheels, working of an engine and the like, are required, and the energy consumption test can be smoothly performed on the vehicle to be tested when the test conditions are met.
The specific process of determining whether the vehicle state meets the test condition may be of various types, and the embodiment of the present invention is not limited herein.
Step S2: if so, acquiring a test working condition;
specifically, the test conditions may be of various types, for example, the test conditions may be corresponding to different countries, for example, test conditions in china, and the energy consumption measured under the test conditions is relatively consistent with the real energy consumption of domestic vehicles.
The obtaining of the test condition may specifically be obtaining a preset condition or obtaining a condition selected by a user through a human-computer interaction device, and the embodiment of the present invention is not limited herein.
Step S3: and controlling the vehicle to be tested to run on the rotary drum according to a preset speed curve corresponding to the test working condition so as to test the energy consumption of the vehicle to be tested.
Specifically, the biggest difference between each working condition is that the speed curves adopted in the test are different, for example, in the process of running for one hundred kilometers in the test, the starting and stopping conditions of the automobile when traffic lights are needed to be simulated, which includes the number of the traffic lights, the speed change and the highest speed in the process, and the corresponding speeds of different working conditions are different.
Specifically, the general speed curve includes the speed to be followed by the vehicle to be tested in the whole test process, so that the vehicle to be tested can be controlled to run on the rotary drum according to the preset speed curve, a professional driver is replaced, and the labor cost is directly reduced.
After the speed control is performed, the staff can obtain the energy consumption data by monitoring the energy surplus at the beginning of the test and the energy surplus at the end of the test so as to obtain the energy consumption test result.
The invention provides a control method for energy consumption testing by a working condition method, which can control a vehicle to be tested to run on a rotary drum according to a preset speed curve corresponding to a testing working condition when the vehicle state of the vehicle to be tested accords with the testing condition.
On the basis of the above-described embodiment:
as a preferred embodiment, after determining whether the vehicle state of the vehicle to be tested meets the test condition, the control method for energy consumption test by the working condition method further includes:
and if not, prompting the items which do not accord with the test conditions in the vehicle state.
Specifically, considering that a worker may not adjust the vehicle state in advance due to carelessness or other reasons at some times, for example, a limited power fault in the vehicle power system is not eliminated in advance, so that the test cannot be performed smoothly and the reason cannot be found.
The prompting device may be of various types, for example, a display of a computer connected to the rotating drum, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, the test conditions include:
the power system is started and has no fault;
the test conditions further include:
if the driver is in the seat, the seat belt must be in at least one of a fastened state, normal tire pressure, closed door, and closed front and rear hatches.
Specifically, the necessary condition for performing the energy consumption test is that the power system must be started, so that the energy consumption of the vehicle to be tested can be discussed, and the energy consumption test must be performed under the condition that the power system of the vehicle is free from faults, otherwise, the measured energy consumption data has no reference value, for example, under the condition that the vehicle speed is limited to be faulty, the speed of the vehicle to be tested cannot be controlled to reach a higher speed in a preset speed curve in the test process, so that the accuracy of the energy consumption test is reduced.
Wherein, the power system has no fault and specifically can be as follows:
if the vehicle to be tested is a fuel oil powered vehicle, the power system has no fault, specifically, no engine shutdown fault, no power limit fault, no vehicle speed limit fault and no torque limit fault;
if the vehicle to be tested is an electric vehicle, the power system has no fault, specifically, no high-voltage power-off fault, no power-limiting fault, no speed-limiting fault and no torque-limiting fault exist, and a Ready lamp of the electric vehicle is turned on.
Of course, the power system failure may include other specific types besides the above-mentioned type of power system failure, and the embodiment of the present invention is not limited herein.
Specifically, if a driver is in a seat, the safety belt needs to be in a fastening state to guarantee the safety of the driver, in case of out-of-control vehicle, the safety of the driver can be guaranteed, the tire pressure can be normal, the safety can be improved, the testing accuracy can be improved, and the safety and the testing accuracy can be improved when the vehicle door is closed and the front and rear hatches are closed.
And the Ready lamp of the electric automobile is lightened, so that the power system of the electric automobile can normally run.
Of course, in addition to these additional conditions, some other conditions that may affect the safety and the accuracy of the test result may be added to the test condition, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, after controlling the vehicle to be tested to run on the rotating drum according to a preset speed curve corresponding to the test condition, the control method for the condition-based energy consumption test further includes:
and when the energy consumption test is finished, controlling the driving torque and the braking force of the vehicle to be tested to be zero and controlling the strategy gear of the vehicle to be tested to be neutral.
Specifically, in consideration of the fact that in the prior art, after the test is finished, a driver can control the driving torque and the braking force of the vehicle to be tested to be zero and control the strategy gear of the vehicle to be tested to be in a neutral gear, the embodiment of the invention can also automatically control the driving torque and the braking force of the vehicle to be tested to be zero when the energy consumption test is finished, and control the strategy gear of the vehicle to be tested to be in the neutral gear, so that the safety termination of the test process is ensured, manual interference is not needed, the labor cost is further reduced, and the automation degree is improved.
In addition, it is worth mentioning that the worker can also send a 'test stopping' instruction through the human-computer interaction interface in the energy consumption testing process, and when the 'test stopping' instruction is received, the controller can also control the driving torque and the braking force of the vehicle to be tested to be zero, the strategy gear of the vehicle to be tested to be a neutral gear, and the rotating speed of the rotary drum to be reduced to zero within a first preset time period, so that the vehicle to be tested stops moving.
The speed at which the rotating drum speed is reduced may be autonomously set, for example, may be a speed of-5 Kph/s, and the first preset time period may also be autonomously set, for example, may be 5 seconds, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, after controlling the vehicle to be tested to run on the drum according to the preset speed curve corresponding to the test condition, before the energy consumption test is finished, the control method for the energy consumption test by the condition method further includes:
when any one of an accelerator pedal, a brake pedal and a steering wheel of the vehicle to be tested acts, controlling the driving torque and the braking force of the vehicle to be tested to be zero, controlling the strategy gear of the vehicle to be tested to be neutral, and controlling the rotating speed of the rotary drum to be zero within a first preset time period so as to stop the vehicle to be tested.
Specifically, considering that some workers may sit in a driver seat to monitor the test process in the energy consumption test process, and that the workers may accidentally touch one of an accelerator pedal, a brake pedal and a steering wheel due to other factors, so that the wheel rotation action of the electric vehicle is influenced, and the accuracy of the energy consumption test result is influenced.
Of course, in the process, one of an accelerator pedal, a brake pedal and a steering wheel which has a misoperation can be synchronously prompted, so that a worker can know the reason of the test termination.
The steering wheel rotation may be determined when the rotation angle of the steering wheel is greater than a preset angle, where the preset angle may be set autonomously, for example, may be set to 5 degrees, and the embodiment of the present invention is not limited herein.
As a preferred embodiment, the step of determining whether the vehicle state of the vehicle to be tested meets the test condition specifically includes:
acquiring a vehicle state detection signal of a specified type in a main controller of a vehicle to be detected;
judging whether the vehicle state of the vehicle to be tested meets the test condition or not according to the vehicle state detection signal;
before obtaining a vehicle state detection signal of a specified type in a main controller of a vehicle to be tested, the control method for the energy consumption test by the working condition method further comprises the following steps:
establishing signal connection with a main controller of a vehicle to be tested and judging whether the signal connection is successfully established;
if the signal connection is successfully established, executing the step of acquiring the vehicle state detection signal of the specified type in the main controller of the vehicle to be detected, otherwise prompting that the signal connection is failed to be established.
Specifically, in the embodiment of the invention, a worker CAN pre-establish a signal connection path between the external processor and the main controller of the vehicle to be tested, CAN use a computer connected with the rotary drum as the external processor, and connect the external processor with the vehicle to be tested through the CAN bus, and then the external processor CAN send a handshake signal to the main controller of the vehicle to be tested and establish signal connection after responding to a signal connection instruction sent by a user through the human-computer interaction device.
Specifically, the external processor can judge whether the vehicle state of the vehicle to be tested meets the test condition or not by acquiring the vehicle state detection signal of the specified type in the main controller of the vehicle to be tested and according to the vehicle state detection signal, and an additional detection device is not required to be installed, so that the cost is saved.
The embodiment of the invention can also prompt when the signal connection between the external processor and the vehicle main controller fails to be established, so that the working personnel can deal with the problems in a targeted manner, and the working efficiency is improved.
As a preferred embodiment, after controlling the vehicle to be tested to run on the drum according to the preset speed curve corresponding to the test condition, before the energy consumption test is finished, the control method for the energy consumption test by the condition method further includes:
if the vehicle to be tested does not meet any test condition, the signal connection between the vehicle to be tested and the main controller of the vehicle to be tested fails, the longitudinal acceleration of the vehicle to be tested is greater than a first preset threshold value, and the lateral acceleration of the vehicle to be tested is greater than a second preset threshold value, the driving torque and the braking force of the vehicle to be tested are controlled to be zero, the strategy gear of the vehicle to be tested is in a neutral position, and the rotating speed of the rotary drum is reduced to zero within a first preset time period, so that the vehicle to be tested stops moving.
Specifically, if any test condition is not met, the vehicle to be tested cannot move normally, which affects the energy consumption test result (for example, when a power limit fault occurs), and if some test conditions are not met, a safety hazard (for example, insufficient tire pressure) may exist, so that the test is terminated in this case.
Specifically, if the signal connection with the main controller of the vehicle to be tested fails, the vehicle to be tested is likely to move according to the current target speed received last, but the processor still considers that the vehicle to be tested is running according to the speed in the speed curve and controls the rotating speed of the rotary drum to be matched with the speed in the speed curve, so that the fixed speed of the vehicle to be tested is not matched with the changing speed of the rotary drum, and the vehicle to be tested is likely to rush out of the rotary drum to cause danger.
Considering that in normal conditions, when a vehicle to be tested is tested on the rotary drum, although the wheels and the rotary drum rotate, the vehicle to be tested is relatively static with the ground, if the longitudinal acceleration of the vehicle to be tested is greater than a first preset threshold value or the lateral acceleration of the vehicle to be tested is greater than a second preset threshold value, it is proved that the vehicle to be tested and the ground move relatively, and harm is likely to be caused to surrounding workers, so that the test termination can be controlled at the moment to ensure safety.
The first preset threshold and the second preset threshold may be set independently, for example, the first preset threshold may be 0.5m/s2The second preset threshold is 0.2m/s2And the embodiments of the present invention are not limited herein.
As a preferred embodiment, after controlling the vehicle to be tested to run on the drum according to the preset speed curve corresponding to the test condition, before the energy consumption test is finished, the control method for the energy consumption test by the condition method further includes:
if the duration time that the absolute difference value between the current target vehicle speed and the actual vehicle speed of the vehicle to be tested is larger than a third preset threshold value exceeds a second preset time length, or the times that the absolute difference value is larger than the third preset threshold value exceeds preset times, controlling the driving torque and the braking force of the vehicle to be tested to be zero, controlling the strategy gear of the vehicle to be tested to be neutral, and reducing the rotating speed of the rotary drum to be zero in the first preset time length so as to stop the vehicle to be tested from moving.
Specifically, considering that the accuracy of the energy consumption test result is poor when the matching between the actual vehicle speed and the current target vehicle speed is poor, the embodiment of the invention can judge the matching condition between the actual vehicle speed and the current target vehicle speed, terminate the test when the absolute difference between the actual vehicle speed and the current target vehicle speed is large and the duration is long or the absolute difference exceeds a third preset threshold for multiple times, and prompt a worker when the test is terminated so as to facilitate the maintenance of the worker.
The prompt to the staff can be performed in various ways, for example, the prompt can be performed through a display, and the content of the prompt can include possible factors that the actual vehicle speed is poorly matched, so that the staff can check the vehicle item by item.
Specifically, the third preset threshold, the second preset time and the preset times may all be set independently, for example, the third preset threshold may be 2Km/h, the second preset time may be 4s, the preset times may be 3 times, and the like, and the embodiment of the present invention is not limited herein.
Possible factors of poor matching of the actual vehicle speed specifically include:
1) a Vehicle main controller, namely a VCU (Vehicle Control Unit) sets errors (Vehicle servicing quality, wheel radius, transmission system efficiency, transmission ratio, sliding resistance and the like) according to parameters adopted when a Vehicle power-assisted system to be tested is controlled by the current target Vehicle speed;
2) the engine/drive motor is not properly executing the VCU torque command;
3) an ESP (Electronic Stability Program) does not correctly execute the brake force command of the VCU;
4) abnormal frictional resistance exists in a vehicle power system and a transmission system.
As a preferred embodiment, after the vehicle state of the vehicle to be tested meets the test condition and before the test condition is obtained, the control method for the energy consumption test by the condition method further includes:
and controlling the functional state of the vehicle chassis system to be tested to be a preset state.
Specifically, the vehicle chassis system comprises some functional states, and if the functional states are not set properly, the energy consumption test process can be affected, so that the accuracy of the energy consumption test is reduced.
As a preferred embodiment, the controlling the functional state of the vehicle chassis system to be tested to be the preset state specifically includes:
controlling AH (Auto Hold), DTC (Drag Torque Control), and TCS (Traction Control System) of the ESP System to be turned off;
controlling an EPB (Electrical Park Brake) function to be closed;
the Steering wheel return is controlled by an EPS (Electric Power Steering).
Specifically, for example, when the automatic parking function is started, if a moment when the speed is zero in the middle of a preset speed curve exists, when the speed is zero, the automatic parking function may lock wheels, so that the speed of the vehicle cannot be increased, and the energy consumption test cannot be continued.
Of course, besides the above listed examples, the control of the functional state of the vehicle chassis system under test to the preset state may also include other types, and the embodiment of the present invention is not limited herein.
Referring to fig. 2, fig. 2 is a control device for energy consumption testing by a working condition method, applied to a processor, and including:
the judging module 1 is used for judging whether the vehicle state of the vehicle to be tested meets the testing condition or not, and if so, the obtaining module is triggered;

and the control module 3 is used for controlling the vehicle to be tested to run on the rotary drum according to a preset speed curve corresponding to the test working condition so as to test the energy consumption of the vehicle to be tested.
