Referring to fig. 1, the embodiment discloses an ASR detection method including steps S100 to S500, and the ASR detection method of the embodiment is applied to an ASR detection device, referring to fig. 2, the ASR detection device includes a stand 100, a first roller 200, a second roller 300, and a resistance mechanism 500, wherein the first roller 200 and the second roller 300 are rotatably mounted on the stand 100, a first vehicle speed sensor 210 is mounted on the first roller 200, a second vehicle speed sensor 310 is mounted on the second roller 300, and the resistance mechanism 500 is connected with a coupling 510 and is connected with the first roller 200 or the second roller 300 through the coupling 510. Details of the various steps are discussed below:
s100, the vehicle to be tested is moved onto the bench 100, and left and right wheels of the vehicle to be tested are respectively positioned on the first roller 200 and the second roller 300.
The moving modes of the vehicle to be tested include, but are not limited to, the following modes:
In a first way, the vehicle to be tested is driven onto the stand 100 by the test person in a start-up state, in which way, in order to avoid free rolling of the first roller 200 and the second roller 300 affecting the movement of the vehicle to be tested, the ASR test device further comprises a braking mechanism 400, which braking mechanism 400 can be in braking connection with the first roller 200 and the second roller 300, respectively. Thus, step S100 further includes, before:
s110, the first drum 200 and the second drum 300 are braked by the brake mechanism 400.
In this case, the brake mechanism 400 locks the first and second drums 200 and 300, and the first and second drums 200 and 300 cannot freely roll, thereby providing sufficient static friction to the vehicle to be tested, so that the vehicle to be tested can be moved to a proper position. Of course, in some application examples, brake mechanism 400 may be an external component relative to the ASR detection device, i.e., ASR detection device and brake mechanism 400 are two separate sets of devices, which may be configured or disassembled according to the needs of the user, which may be advantageous for increased flexibility of use.
In a second way, the vehicle to be tested may be placed on a mobile platform and moved by the mobile platform onto the rack 100. In this case, it is possible to eliminate consideration of the influence of the rolling of the first and second drums 200 and 300 on the movement of the vehicle to be tested.
It should be noted that, in order to achieve effective detection of ASR performance of a vehicle, the vehicle to be tested in this embodiment refers to a vehicle equipped with an ASR system, and for a vehicle not equipped with an ASR system, the detection result is that the ASR system fails. The left and right wheels of the vehicle to be tested according to the present embodiment are wheels that can supply power to the vehicle and are controlled by the ASR system of the vehicle to be tested, for example, the left and right wheels of the vehicle to be tested are left and right front wheels for a front wheel driven vehicle, the left and right wheels of the vehicle to be tested are left and right rear wheels for a rear wheel driven vehicle, and for a four wheel driven vehicle, detection can be performed in a manner of driving the vehicle by the front wheels and driving the vehicle by the rear wheels, respectively.
To accommodate the wheel sizes of different vehicles, the number of the first rollers 200 and the second rollers 300 may be one or more, for example, the number of the first rollers 200 and the second rollers 300 shown in fig. 2 is three, three first rollers 200 are arranged side by side, a first speed sensor 210 is mounted on the middle first roller 200, and the second rollers 300 are arranged in the same manner as the first rollers 200, wherein the middle second roller 300 is connected with the resistance mechanism 500 through a coupling 510. Of course, the resistance mechanism 500 may be coupled to the first roller 200 through a coupling 510.
S200, starting the vehicle to be tested and accelerating the vehicle to be tested so that the vehicle to be tested drives the first roller 200 and the second roller 300 to rotate through the left wheel and the right wheel respectively.
The ASR system of the vehicle is used for preventing slip during acceleration of the vehicle, so that the vehicle to be tested needs to be started and accelerated during testing to simulate running or acceleration of the vehicle. When the vehicle to be tested is accelerated, since the first drum 200 and the second drum 300 are in a free rolling state, the left and right wheels of the vehicle to be tested can respectively drive the first drum 200 and the second drum 300 to rotate, and the rotation speeds of the first drum 200 and the second drum 300 respectively correspond to the left and right wheels of the vehicle to be tested under the condition of no external force, so that the running or accelerating state of the vehicle to be tested can be determined by detecting the speeds of the first drum 200 and the second drum 300.
In the case where the first drum 200 and the second drum 300 are braked by the brake mechanism 400, the step S200 is preceded by:
S210, releasing the braking of the first drum 200 and the second drum 300 by the braking mechanism 400. In this way, the first drum 200 and the second drum 300 can be freely rotated.
In this embodiment, in consideration of slip and detection safety caused by different adhesion coefficients of the vehicle running when the vehicle to be tested starts, after braking of the first drum 200 and the second drum 300 by the brake mechanism 400 is released, the speed of the vehicle to be tested is raised to 20±3km/h, which is favorable for obtaining better speed sampling, thereby ensuring the detection effect of ASR performance effectiveness.
And S300, providing resistance to the first roller 200 or the second roller 300 through the resistance mechanism 500 so as to stop the rotation of the first roller 200 or the second roller 300.
In practice, the resistance mechanism 500 may be connected to the first drum 200 or the second drum 300, and the resistance mechanism 500 provides resistance to the first drum 200 when the resistance mechanism 500 is connected to the first drum 200, and provides resistance to the second drum 300 when the resistance mechanism 500 is connected to the second drum 300. In this embodiment, the resistance mechanism 500 provides resistance to the second drum 300 to stop the rotation of the second drum 300, thereby simulating the slip of the left wheel of the vehicle under test.
It should be noted that, in the description of the present embodiment, the continuous reference numerals of the method steps are used for facilitating examination and understanding, and the technical effects achieved by the technical scheme of the present invention are not affected by adjusting the implementation sequence of the steps in combination with the overall technical scheme of the present invention and the logic relationships between the steps. For example, in some application examples, the implementation sequence of step S200 and step S300 is exchanged, that is, before the vehicle to be tested starts and speeds up, the first drum 200 or the second drum 300 is provided with resistance by the resistance mechanism 500, so as to simulate the situation of starting and slipping of the vehicle.
In some examples of applications, resistance mechanism 500 employs an eddy current motor. Compared with the resistance mode of the brake pad, the resistance mode of the brake pad is accurate and flexible in stress application by providing resistance through the vortex motor, different resistance to different vehicle types and different speed loads can be set, the vortex motor can avoid the situation that the resistance mechanism 500 is seriously worn under the condition of overcoming huge reaction force by utilizing the non-contact stress application mode of an electromagnetic principle, and the brake pad has long service life and does not need maintenance. In order to meet the resistance requirement of the test, the output power of the eddy current motor is larger than or equal to 160kw, and the eddy current motor outputs resistance in a constant voltage mode, for example, 6300N resistance is output when the speed is measured at 40km/h, so that the resistance requirement of the test is met.
In order to ensure the effectiveness of the detection, the friction coefficients of the first roller 200 and the second roller 300 are greater than or equal to 0.7, so that the normal road running condition can be fully simulated, the wheels of the vehicle to be detected can be well contacted with the first roller 200 or the second roller 300, and unexpected slipping caused by insufficient friction force is avoided, and the detection is failed.
S400, a first speed of the first drum 200 is detected by the first vehicle speed sensor 210, and a second speed of the second drum 300 is detected by the second vehicle speed sensor 310.
As can be seen from the above discussion, when the first drum 200 and the second drum 300 are in the free rolling state, the wheel speeds of the vehicle to be measured correspond to the speeds of the first drum 200 and the second drum 300, and thus, the driving condition of the vehicle to be measured can be indirectly obtained by detecting the speeds of the first drum 200 and the second drum 300 by the first vehicle speed sensor 210 and the second vehicle speed sensor 310, respectively. When resistance is provided to the second drum 300 by the resistance mechanism 500, the speed of the second drum 300 gradually decreases until it becomes zero, so that it is possible to simulate a situation in which a slip occurs in the vehicle while running. At this time, the ASR function of the vehicle under test is effective to distribute the traction force of the left wheel to the right wheel, so that the second drum 300 starts to rotate against the resistance. In this manner, by observing the speed change between the first roller 200 and the second roller 300, it can be determined whether the ASR performance of the vehicle under test is effective.
In some examples of applications, to facilitate testing of the tire reaction force of a vehicle under test, the resistance mechanism 500 is provided with a load cell (not shown) for measuring the force applied by the resistance mechanism 500. The load cell returns the sensed data to an external control system to facilitate acquisition of the tire reaction force of the vehicle under test and resistance adjustment of the resistance mechanism 500.
Specifically, the force transducer adopts an S-shaped sensor or a torsion sensor, and the S-shaped sensor has the advantages of high measurement precision, wide measurement range, convenience in installation and the like, has stable performance and is beneficial to improving the reliability of detection.
S500, determining the effectiveness of the ASR performance of the vehicle to be tested according to the first speed and the second speed.
As can be seen from the above discussion, in the present embodiment, during testing, the left and right wheels of the vehicle to be tested are respectively located on the first roller 200 and the second roller 300, the left and right wheels of the vehicle to be tested rotate to drive the first roller 200 and the second roller 300 to rotate, the resistance mechanism 500 provides resistance to the first roller 200 or the second roller 300 to simulate a slip condition, and the speed of the first roller 200 and the second roller 300 is detected by the first vehicle speed sensor 210 and the second vehicle speed sensor 310 to detect whether the ASR system of the vehicle to be tested is effective, so as to realize the ASR performance effectiveness detection of the vehicle to be tested.
The ASR detection method according to an embodiment of the present invention is described in detail below with reference to fig. 3 as a specific example. It is to be understood that the following description is exemplary only and is not intended to limit the invention in any way.
After the vehicle to be tested is moved onto the bench 100, the vehicle to be tested is started, the speed of the vehicle to be tested is increased to 20+/-3 km/h, after the speed of the vehicle to be tested is stabilized, the resistance mechanism 500 provides resistance for the second roller 300, so that the condition that the vehicle runs to the road surface with uneven adhesion coefficient is simulated, when the vehicle to be tested slips, the rotation speed of the wheels in a slipping state is high, the rotation speed of the wheels without slipping is low, the ASR function of the vehicle to be tested takes effect, the traction force of the left wheel is distributed to the right wheel, the speed of the right wheel is gradually increased, and finally the speeds of the left wheel and the right wheel of the vehicle to be tested are balanced.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
