EXPERIMENTATION IN OPEN-LOOP RESPONSE UTILIZING AN AUTOMATIC VEHICLE CONTROLLER
An automatic control system has been developed to permit objective experimental measurement of motor vehicle performance at the limit of tire-road adhesion. Certain characteristics of limit maneuver measurement are discussed which impose a need for the application of precision time histories of steering and braking, exceeding the input fidelity of the unaided test driver. The design of a programmable controller capable of providing precision open-loop control inputs to a motor vehicle is presented in some detail. Based upon substantial full-scale test experience, automatic vehicle controller test practices are reviewed, together with typical findings of vehicle limit response deriving from a sample of representative vehicles. /HSRI/
