<P>PROBLEM TO BE SOLVED: To provide a truck testing device capable of controlling the brake deceleration characteristics of a test truck by high reproducibility, in a predetermined deceleration section, during traveling. <P>SOLUTION: In the truck testing device using a pre-crash test truck 4 tire-traveling along a main rail 2 laid on a truck traveling road surface 3, the pre-crash test truck 4 is provided with a brake deceleration system C adding braking force for controlling the brake deceleration characteristics in the predetermined deceleration section in the whole traveling section. The brake deceleration system C has a front side rail brake 12F and a rear side rail brake 12R obtaining hydraulic braking force by first brake calipers 30, 30 sandwiching the main rail 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
