PROPULSION CONTROL SYSTEM AND METHOD FOR RAILWAY MAINTENANCE VEHICLES

摘要

A propulsion control system is provided for controlling a hydraulic drive system of a railway maintenance vehicle. An axle monitoring module receives and monitors a first signal from a first rotation sensor, and a second signal from a second rotation sensor, the first and second signals associated with first and second axles of the vehicle, respectively. A speed comparison module calculates a delta value representing a difference between the first and second signals, and generates a speed control signal based on the difference. A speed control module receives the speed control signal, and generates a power signal for controlling an amount of power applied to at least one of the first and second axles based on the speed control signal. An actuation control module receives the power signal, and performs a power allocation function for controlling a speed or power of the hydraulic drive system.

1. A propulsion control system for controlling a hydraulic drive system of a railway maintenance vehicle, comprising:
an axle monitoring module configured for receiving and monitoring a first signal received from a first rotation sensor, and a second signal received from a second rotation sensor, the first signal being associated with a first axle of the vehicle, and the second signal being associated with a second axle of the vehicle; a speed comparison module configured for calculating a delta value representing a difference between the first and second signals by comparing values of the first and second signals, and generating a speed control signal based on the comparison; a speed control module configured for receiving the speed control signal, and generating a power signal for controlling an amount of power applied to at least one of the first and second axles based on the speed control signal; and an actuation control module configured for receiving the power signal, and performing a power allocation function for controlling a speed or power of the hydraulic drive system that controls at least one of the first and second axles based on the power signal.
