DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-3 , the present invention provides a technical solution: a new type of intelligent driving test lateral lane change assistance device.

[0020] In response to the above description, there is a trend that dedicated field tests for intelligent driving will gradually replace road tests. However, dedicated vehicle performance tests generally only have longitudinal performance test benches, which cannot meet various regulatory requirements and cannot simulate more traffic attempts, which makes field tests limited.

[0021] The solution is as follows: A new type of intelligent driving test lateral lane change assist device, comprising: a parking platform 1, a tested vehicle 3 is arranged on the upper part of the parking platform 1, a test road 4 is arranged on the side of the parking platform 1, and the surface of the test road 4 is provided with a first track 5 and a second track 6, a lane change assist mechanism 9 is arranged on the surface of the first track 5, a first target vehicle 7 and a second target vehicle 8 are arranged on the surfaces of the first track 5 and the second track 6, the lane change assist mechanism 9 includes a mobile frame 10 and the mobile frame 10 can be connected to the first track 5 and the second track 6, and the surface of the mobile frame 10 is provided with two sets of driving devices The lane change assist mechanism 9 is composed of two sets of multiple scissor-type push rods, a drive device 12, and a follower frame. The two sets of multiple scissor-type push rods are in different states to simulate the driving states of the front and rear same lanes and the left and right adjacent lanes of the vehicle. The two sets of multiple scissor-type push rods are controlled by two sets of drive devices 12 respectively. When the two sets of multiple scissor-type push rods extend by different amounts, the target vehicle changes its stroke angle according to the position change of the turning point, so as to simulate the posture of the vehicle in the actual driving process.

[0022] Further improvements, such as Figure 2 As shown: a moving mechanism 11 is provided at the bottom of the moving frame 10 and the moving mechanism 11 can be connected to the first track 5 and the second track 6. The lane change auxiliary mechanism 9 can move flexibly along the track of the test road 4 to adapt to different test scenarios and route requirements.

[0023] Further improvements, such as Figure 2 As shown: a controller 16 is provided on the surface of the mobile frame 10 and the controller 16 is connected to the driving device 12. The driving device 12 is precisely controlled by the controller 16, so that the extension and retraction actions of the scissor-type push rod can be precisely adjusted, thereby more accurately simulating the posture changes of the vehicle during the lane change process and improving the accuracy and reliability of the test.

[0024] Further improvements, such as Figure 2 As shown: the scissor-type push rod includes a plurality of groups of connecting rods 13, two adjacent groups of the connecting rods 13 are cross-arranged and a central axis 15 is arranged at the intersection, and connecting shafts 14 are arranged on both sides of the two adjacent groups of the connecting rods 13. The design structure of the scissor-type push rod is compact and stable, can withstand large forces and produce a stable motion trajectory, thereby more realistically simulating the mechanical characteristics of the vehicle when changing lanes and improving the reliability of the test results.

[0025] Further improvements, such as Figure 2 As shown: the surface of the parking platform 1 is provided with a vehicle limiting seat 2 and the vehicle 3 to be tested is parked on the surface of the vehicle limiting seat 2. The vehicle limiting seat 2 can ensure that the vehicle 3 to be tested maintains a stable parking position during the test.

[0026] Further improvements, such as Figure 2 As shown: a mounting seat 18 is provided on the surface of the connecting seat 17 and the mounting seat 18 is connected to the first target vehicle 7 and the second target vehicle 8, so that the target vehicles can be conveniently connected to the connecting seat 17, thereby forming a complete lane change assist mechanism 9 system with components such as a scissor push rod.

[0027] Further improvements, such as Figure 2 As shown: a swivel seat 19 is arranged on the surface of the connecting seat 17 and a power device is arranged on the side of the swivel seat 19. The arrangement of the swivel seat 19 and the power device enables the target vehicle to perform a rotational motion during the lane change process to simulate the steering action of the vehicle in actual driving.

[0028] Working principle: The lane-changing auxiliary mechanism 9 of the present invention is composed of two sets of multiple scissor-type push rods, a driving device 12, and a follow-up frame. The two sets of multiple scissor-type push rods are in different states to simulate the driving states of the front and rear lanes and the left and right adjacent lanes of the vehicle. The two sets of multiple scissor-type push rods are controlled by two sets of driving devices 12 respectively. When the extension amounts of the two sets of multiple scissor-type push rods are different, the target vehicle will simulate the posture of the vehicle in the actual driving process according to the position change of the turning point and the stroke swing angle. When there is a vehicle failure or low-speed driving in front of the road where the tested vehicle 3 is driving, and the first target vehicle 7 in front of the tested vehicle 3 is approaching the second target vehicle 8 that is failure or low-speed driving, the emergency lane-changing vehicle cuts out to test the coping strategy of the tested vehicle 3 And the response results; when the test starts, the lane change assist mechanism 9 is in an extended state, so that the tested vehicle 3, the first target vehicle 7 and the second target vehicle 8 drive relative to each other in the same lane line; when the first target vehicle 7 and the second target vehicle 8 reach the predetermined position, the lane change assist mechanism 9 retracts, completing the lane change and cut-out function of the first target vehicle 7, and completing the test condition; when the test starts, the lane change assist mechanism 9 is in a retracted state, and when the first target vehicle 7 and the second target vehicle 8 reach the predetermined position, the lane change assist mechanism 9 changes from a retracted state to an extended state, so that the first target vehicle 7 is inserted between the second target vehicle 8 and the tested vehicle 3. This condition can simulate the emergency insertion and merging condition of the adjacent vehicle.
