STEERING CONTROLLER FOR CRAWLER TYPE WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To notify an operator of an anomaly by signaling that right and left output rotational speeds of crawler units do not match when a steering wheel is turned in a straight traveling direction in a crawler type work vehicle arranged with a transmission mechanism changing output rotation speeds to right and left crawler units by operation of an actuator. SOLUTION: When sensor values RL and RR of right and left crawler rotation sensors do not match even though a sensor valueθof a steering turning angle sensor is zero degrees, it is determined that there is an anomaly in the steering turning angle sensor, and a controller signals about a neutral position deviation by lighting or flashing or the like of a lamp.
