Document Type and Number:
Japanese Patent JP5887288
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a wheel loader that an engine rotating speed and a tractive force may become estranged but the current tractive force can be grasped easily.SOLUTION: Maximum travelling driving torque TQv fixed to every vehicle speed V for travelling driving torque of a traction motor generating the travelling driving torque input to wheels is calculated based on a current vehicle speed V (S120). A torque ratio Rt which is a proportion of the current travelling driving torque TQc for the maximum travelling driving torque TQv is calculated (S140). The calculated torque ratio Rt is displayed (S150).
