Abstract:
An autonomous mode controller (61) that outputs an acceleration command (SAa), a braking command (SBa) and a torque command (Ta) is connected to a steering actuator (33) and a traveling drive unit (52). The steering actuator (33) generates combined torque (T1) based upon steering torque (Tm) from a steering handle (32) and the torque command (Ta), and controls a steering angle (θ) of a vehicle based upon the combined torque (T1). The traveling drive unit (52) selects a larger one of an acceleration command (SAm) by an accelerator pedal (50) and the acceleration command (SAa) as an acceleration command (SA), and selects a larger one of a braking command (SBm) by a brake pedal (51) and the acceleration command (SBa) as a braking command (SB). The traveling drive unit (52) controls a vehicle speed based upon the acceleration command (SA) and the braking command (SB).
