Title:
VEHICLE COLLISION TEST DEVICE
Document Type and Number:
Japanese Patent JP2023123149
Kind Code:
A
Abstract:
To solve the problem that the vehicle speed deviates from a predetermined speed at a separation position of a vehicle by changing the traction speed of a motor according to the load amount on a traction motor near the completion of acceleration shifting from acceleration having a large influence on the traction speed to traction to the constant speed.SOLUTION: Disclosed is a vehicle collision test device which includes: a traction rope 1; a drum 2 for pulling the traction rope 1; a motor 4 for driving the drum 2; and control means 5 for controlling input of a torque command Tr to the motor 4 based on a traction speed command Vref, and performs a collision test by connecting a vehicle 7 to the traction rope 1 through a dolly 6 as connection/disconnection switching means. The control means 5 is configured to correct the traction speed command Vref of the motor 4 in the direction of reducing the load amount according to the load amount of the motor 4 at a predetermined timing near the completion of acceleration.SELECTED DRAWING: Figure 1
