Chassis dynamometer for testing a two wheel drive vehicle, control method for the same, and chassis dynamometer program for testing a two wheel drive vehicle

A control method for a chassis dynamometer that tests a two-wheel drive vehicle, the chassis dynamometer including a driving wheel side roller on which driving wheels of the vehicle are placed, a driven wheel side roller on which driven wheels of the vehicle are placed, a driving wheel side power absorbing part connected to the driving wheel side roller, and a braking force measuring part that measures braking force of a driven wheel side brake exerted on the driven wheel side roller, wherein the driving wheels are front or rear wheels of the vehicle and wherein the driven wheels are the other of the front or rear wheels of the vehicle, the control method comprising:

• with use of the braking force measured by the braking force measuring part, setting a control target value of power absorbing force of the driving wheel side power absorbing part to control the driving wheel side power absorbing part, and
• operating the driving wheel side roller and driven wheel side roller at a same time.

A tangible, non-transitory computer-readable medium storing instructions that, when executed by a computer, cause the computer to instruct a chassis dynamometer, that tests a two-wheel drive vehicle and includes a driving wheel side roller on which driving wheels of the vehicle are placed, a driven wheel side roller on which driven wheels of the vehicle are placed, a driving wheel side power absorbing part connected to the driving wheel side roller, and a braking force measuring part that measures braking force of a driven wheels side brake exerted on the driven wheel side roller,

• to set a control target value of power absorbing force of the driving wheel side power absorbing part to control the driving wheel side power absorbing part with use of the braking force measured by the braking force measuring part, wherein the driving wheels are front or rear wheels of the vehicle and wherein the driven wheels are the other of the front or rear wheels of the vehicle, and
• to operate the driving wheel side roller and driven wheel side roller at a same time.
