A programmable digital vehicle control system or PVDCS is based upon a microprocessor and is designed to replace the hardwired discrete components traditionally used in the on-board control of automated rapid transit vehicles. The PDVCS can easily be adapted for use in any automated transit system. A breadboard PDVCS has been programmed to perform the basic longitudinal control system functions, including closed-loop emergency braking, and has been subjected to closed-loop laboratory testing. Prototype tachometers and a seventh-order nonlinear analog computer simulation of motor, brake, and vehicle dynamics were used to close the control loop for test purposes; command scenarios were input manually. The test results demonstrate the feasibility of microcomputers in on-board vehicle control and show their capability to meet the performance requirements associated with a short headway (3 s) system.
