Abstract: Systems and method of calibrating a range measurement system for a vehicle mounted on a guideway are disclosed. In some embodiments, a method includes: measuring a first time of transmission (TOT) between a first internal component of an on-board range measurement device and a second internal component of a wayside range measurement device. The first TOT is compared with a first pre-determined time. A health of the range measurement system is determined based on a difference between the first TOT and the first pre-determined time.

Abstract: A control system for a vehicle includes a first controller, a second controller, and an auto-tuner. The first controller is configured to generate an optimal trajectory of the vehicle along a path. The second controller is configured to, based on the optimal trajectory generated by the first controller, generate motoring and braking commands to a motoring and braking system of the vehicle for controlling the vehicle to travel along the path. The auto-tuner includes a processor configured to solve a real-time optimization problem to determine at least one parameter of at least one of the first controller or the second controller.

Abstract: A positioning and odometry system (POS) includes one or more sensors configured to collect sensor data. The one or more sensors are operably coupled to a portable housing configured to be coupled to a vehicle body. POS has processing circuitry operably coupled to the one or more sensors. The processing circuitry is configured to determine, in response to the collected sensor data from the one or more sensors, vehicle position and odometry data.
