Haulage vehicle
First Claim
1. A haulage vehicle comprising:
- an acceleration operation device that operates acceleration of a vehicle;
a braking operation device that operates a brake of said vehicle; and
a traveling drive unit that causes said vehicle to travel based upon an acceleration command by said acceleration operation device and a braking command by said braking operation device, characterized in that;
said traveling drive unit comprises;
an external input terminal for inputting another acceleration command and another braking command from an exterior;
an acceleration command selecting unit that selects a larger acceleration command by comparing said other acceleration command input from said external input terminal and said acceleration command by said acceleration operation device; and
a braking command selecting unit that selects a larger braking command by comparing said other braking command input from said external input terminal and said braking command by said braking operation device, whereina traveling drive of said vehicle is controlled based upon said acceleration command selected by said acceleration command selecting unit and said braking command selected by said braking command selecting unit.

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).
