Referring to fig. 1-3, embodiments of the present application provide a test method. The method comprises the following steps:
s10, when the driver sits on the driver 'S seat 10, the leg of the driver is tightened on the driver' S seat 10 by the tightening member 100.
And S20, controlling the vehicle 20 to travel over the barrier device 30 provided on the ground 40.
And S30, controlling the vehicle 20 to reverse over the barrier device 30.
The state of the vehicle 20 is checked S40.
In the vehicle 20 test method according to the embodiment of the present application, the leg portion of the driver is tightened on the driver's seat 10 by the tightening member 100, so that the driver can be prevented from bouncing up when the vehicle 40 passes over the barrier device 30, and the weight load of the driver can be surely input to the vehicle 20. Forward and reverse tests are performed on the vehicle 20 at the same time, which may effectively verify the entire vehicle.
Specifically, in step S10, the tightening member 100 includes a flexible member such as a strap 102, and referring to fig. 2, the driver' S seat 10 includes a receiver 101, a strap 102, a seat belt 103, and a base plate 104. The container 101 is fixed on the bottom plate 104; the strap 102 is attached to the container 101; the seat belt 103 binds the chest of the driver; the base plate 104 is welded to a mounting bracket of the operator's seat 10, which is bolted to the vehicle 20, see fig. 3. Of course, in other embodiments, lacing member 100 may be a rigid member.
It can be understood that when the vehicle is in collision, the body of the driver rushes forward instantly, the safety belt 103 is suddenly tightened, and the driver is firmly fixed, so as to play a role in protection. The vehicle 20 comprises a driver seat 10, a chassis, a suspension, a power assembly, an electronic device, a vehicle body and other systems, and the safe driving of the vehicle is ensured. The binding band 102 is used for binding the thigh part of the driver, plays a role in fixing, and avoids the situation that the driver can be bounced to cause that the chassis part on one side of the driver cannot be fully verified during testing. The number of the straps 102 may be one, two, three, etc., and a plurality of straps 102 can ensure a more secure fixation. In the test, the driver sits in the driver seat 10, fastens the seat belt 103, and tightens the leg portion with the strap 102. Thus, it is possible to prevent the driver from bouncing up when the vehicle passes over the road block.
In step S20, the driver controls the vehicle 20 to travel forward over the barrier device 30 provided on the ground 40. Fig. 4 shows a schematic view of the barrier unit 30. the barrier unit 30 may be made of wood/stone, and the lower half of the barrier unit 30 is embedded in the ground 40 to ensure that the barrier unit 30 is fixed to the ground 40, and the top of the barrier unit 30 is higher than the ground 40. The driver performs a strength test by controlling the vehicle 20 to travel over the barrier device 30, observes the condition of the body and the condition of parts of the vehicle 20, and verifies whether or not the vehicle 20 can have a strength that sufficiently exhibits the performance required of the vehicle 20 when traveling over the barrier device 30.
In step S30, the driver controls the vehicle 20 to reverse over the barrier device 30 provided on the ground 40. The driver can perform a strength test by controlling the vehicle to move backward 20 over the barrier device 30, observe the condition of the body and the condition of the parts of the vehicle 20, and verify whether the vehicle 20 has a strength sufficient to exert the performance required of the vehicle 20 when moving backward over the barrier device 30.
In step S40, after steps S20 and S30, the state of the vehicle 20 is checked to determine whether the vehicle 20 can pass the test. The assessment criteria may be as follows:
1. the body and chassis parts are allowed to deform but not to break; failure of function due to structural deformation is not allowed;
2. the parts do not fall off or fall off, and the vehicle can steer and safely drive for 50 m;
3. the power system can not have the phenomena of cracking, functional failure, leakage, fire and the like;
if the vehicle 20 meets the above 3 criteria at the same time, it can be determined that the vehicle 20 passes the test. Alternatively, the vehicle 20 does not pass the test when the vehicle 20 does not meet at least one of the above 3 criteria. Specifically, if the vehicle 20 meets the first criterion, and does not meet the second criterion and the third criterion, it is determined that the vehicle 20 fails the test; if the vehicle 20 meets the second criterion, and does not meet the first criterion and the third criterion, determining that the vehicle 20 fails the test; if the vehicle 20 meets the third criterion, and does not meet the first criterion and the second criterion, determining that the vehicle 20 fails the test; if the vehicle 20 meets the first criterion, the second criterion and the third criterion, judging that the vehicle 20 does not pass the test; if the vehicle 20 meets the second criterion and the third criterion, and does not meet the first criterion, determining that the vehicle 20 fails the test; if the vehicle 20 meets the first criterion, the third criterion and the second criterion, judging that the vehicle 20 does not pass the test; if the vehicle 20 does not meet the first, second, and third criteria, the vehicle 20 is determined to have failed the test.
Referring to fig. 5, in some embodiments, the lacing element 100 includes a strap 102. The tightening member 100 is used to tighten the leg of the driver on the driver' S seat 10 (step S10), and includes:
s11, pulling one end of the binding band 102 out of the container 101 at one side of the driver seat 10;
s12 is to fix one end of the pulled-out strap 102 to a fixing device on the other side of the driver 'S seat 10 across the leg, and to cause the receiver 101 to pull back the strap 102 so that the strap 102 tightens the leg on the driver' S seat 10.
Specifically, in step S11, the strap 102 is stored in the storage 101 on the driver seat 10 side before being used. In the test, the driver needs to pull one end of the strap 102 out of the storage 101.
In step S12, the driver puts one end of the pulled-out strap 102 over his or her leg, and fixes the one end of the pulled-out strap 102 to the fixing device on the other side of the driver' S seat 10. The entire strap 102 is pulled back by the portion rolled in the receiver 102 so that the strap 102 can be firmly fixed to the leg of the driver. In this manner, it is possible to avoid the driver being bounced when the vehicle 20 passes over the barrier device 30, resulting in insufficient verification of the performance of the chassis parts on the driver's side.
Referring to fig. 6, in some embodiments, controlling a vehicle 20 to travel across a barrier unit 30 disposed on a ground surface 40 (step S20) includes:
s21, the vehicle 20 is controlled to advance and the left wheel of the vehicle 20 is made to pass over the barrier device 30 and the right wheel of the vehicle 20 is made to avoid the barrier device 30.
S22, the vehicle 20 is controlled to advance and the right wheel of the vehicle 20 is made to pass over the barrier device 30 and the left wheel of the vehicle 20 is made to avoid the barrier device 30.
Specifically, referring to fig. 7, in step S21, the driver controls the vehicle 20 to move forward and controls the left wheel of the vehicle 20 to pass over the barrier 30, and the right wheel of the vehicle 20 to avoid the barrier device 30, as shown in fig. 7A. The condition of the body and parts of the vehicle 20 when the vehicle 20 is traveling with the left wheel over the barrier device 30 is verified.
In step S22, the driver controls the vehicle 20 to move forward and controls the right wheel of the vehicle 20 to pass over the barrier 30 and the left wheel of the vehicle 20 to avoid the barrier device 30, as shown in fig. 7B. The condition of the body and parts of the vehicle 20 when the right front wheel of the vehicle 20 passes over the barrier device 30 is verified.
The driver controls the driving direction of the vehicle 20 to move forward, and controls the left wheel of the vehicle 20 to cross the barrier device 30 and the right wheel to avoid the barrier device 30; the right wheel of vehicle 20 is then steered over barrier device 30 while the left wheel is steered off of barrier device 30. Therefore, when the vehicle 20 moves forwards to cross the roadblock device 30, the integrity of the body and parts of the vehicle 20 can be verified, and the strength of the whole vehicle parts is optimized and improved.
Of course, in other embodiments, vehicle 20 may be controlled to advance and the left and right wheels of vehicle 20 may simultaneously clear barrier device 30.
Referring to fig. 8, in some embodiments, controlling a vehicle 20 to reverse over a barrier device 30 disposed on a ground surface 40 (step S30) includes:
and S31, controlling vehicle 20 to reverse and move the left wheel of vehicle 20 over barrier device 30 and the right wheel of vehicle 20 away from barrier device 30.
And S32, controlling vehicle 20 to reverse and move the right wheel of vehicle 20 over barrier device 30 and the left wheel of vehicle 20 away from barrier device 30.
Specifically, referring to fig. 9, in step S31, the driver controls the vehicle 20 to reverse and controls the left wheel of the vehicle 20 to clear the barrier device 30, and the right wheel of the vehicle 20 clears the barrier device 30, as shown in fig. 9A. The condition of the body and parts of the vehicle 20 when the left wheel passes over the barrier device 30 when the vehicle 20 is backing up is verified.
In step S32, the driver controls the vehicle 20 to reverse and controls the right wheel of the vehicle 20 to pass over the barrier 30, and the left wheel of the vehicle 20 avoids the barrier device 30, as shown in fig. 9B. The condition of the body and parts of the vehicle 20 when the right wheel passes over the barrier device 30 when the vehicle 20 is backing up is verified.
The driver controls the driving direction of the vehicle 20 to be reverse, and controls the left wheel of the vehicle 20 to cross the barrier device 30 and the right wheel to avoid the barrier device 30; the right wheel of vehicle 20 is then steered over barrier device 30 while the left wheel is steered off of barrier device 30. Therefore, the integrity of the body and parts of the vehicle 20 can be verified when the vehicle 20 backs over the roadblock device 30, and the strength of the parts of the whole vehicle can be improved conveniently.
Referring to fig. 10, in some embodiments, the barrier unit 30 is laterally fixed to the ground 40, and the vehicle 20 is controlled to travel over the barrier unit 30 disposed on the ground 40 (step S20), including:
s200, controlling included angles between the traveling direction of the vehicle 20 and the transverse direction of the roadblock device 30 to be a first angle a, a second angle b and a third angle c respectively to pass through the roadblock device 30 arranged on the ground 40 in a forward mode;

Referring to fig. 11, after the barrier device 30 is fixed on the ground in step S200, the driver controls the vehicle 20 to move forward, and controls the traveling direction of the vehicle 20 and the transverse direction of the barrier device 30 to form a first angle (45 °), a second angle (90 °), and a third angle (135 °), respectively, to move forward over the barrier device 30 disposed on the ground 40.
Referring to fig. 12, after the barrier device 30 is fixed on the ground at step S300, the driver controls the vehicle 20 to reverse, and controls the included angles between the reverse direction of the vehicle 20 and the lateral direction of the barrier device 30 to reverse respectively across the barrier device 30 provided on the ground 40 at first, second, and third angles of 45 °, 90 °, and 135 °.
In some embodiments, the number of times vehicle 20 backs up over barrier device 30 at the first and third angles, respectively, is greater than the number of times vehicle 20 passes over barrier device 30 at the second angle.
The driver controls the vehicle 20 to drive in reverse, reversing over the barrier device 30 disposed on the ground 40, at three angles, a first angle of 45 °, a second angle of 90 °, and a third angle of 135 °, respectively, between the reverse direction and the lateral direction of the barrier device 30.

The driver must control the vehicle 20 to advance over the barrier device 30 at a greater speed than the vehicle 20 would have to travel over the barrier device 30 when reversing. During the test, the forward speed of the vehicle 20 may be 40 + 2km/h and the backward speed of the vehicle 20 may be 20 + 2 km/h.
In some embodiments, the test method includes controlling the vehicle 20 to advance at a first speed when the flattening ratio of the tires of the vehicle 20 is 50% or more and less than 60%; when the flattening ratio of the tires of the vehicle 20 is less than 50%, the vehicle 20 is controlled to advance at a second speed, which is less than the first speed.
Specifically, the aspect ratio is a parameter of the tire, and refers to the percentage of the cross-sectional height of the tire to the maximum width of the cross-section. When the flattening ratio of the tires of the vehicle 20 is 50% or more and less than 60%, the driver controls the vehicle 20 to advance over the barrier device 30 at a first speed of 35 ± 2 km/h; when the flattening ratio of the tires of the vehicle 20 is less than 50%, the vehicle 20 is controlled to advance over the barrier device 30 at a second speed of 30 ± 2 km/h.
In certain embodiments, the test method includes repeating the steps of controlling vehicle 20 to travel forward over barrier unit 30 disposed on ground 40 and controlling vehicle 20 to reverse over the barrier unit a predetermined number of times.
Specifically, during the test, the driver repeats the step of controlling the vehicle 20 to travel at a speed of 40 ± 2km/h over the barrier device 30 provided on the ground 40. The predetermined number of times that the vehicle 20 is traveling across the barrier device 30 at the first angle of 45, the second angle of 90, and the third angle of 135 is 5.
The driver repeats the step of controlling the vehicle 20 to reverse at a speed of 20 + 2km/h, passing over the barrier device 30 provided on the ground 40. Where the predetermined number of times that vehicle 20 backs up over barrier device 30 at first angle of 45 deg. and third angle of 135 deg. are both 7 times and the predetermined number of times that vehicle 20 backs up over barrier device 30 at second angle of 90 deg. is 5 times. See table 1 for details:
TABLE 1
Referring to fig. 13, in some embodiments, barrier unit 30 is raised above ground 40 by a distance [90mm, 110mm ]; and/or the width of barrier unit 30 may range from [80mm, 120mm ].
