Systems and methods for switching between autonomous and manual operation of a vehicle are described. In one embodiment, there is a mechanical
control system that receives manual inputs from a mechanical operation member to operate the vehicle in manual mode. There is further an
actuator that receives
autonomous control signals generated by a controller. When the
actuator is engaged, it operates the vehicle in an autonomous mode, and when disengaged, it operates the vehicle in manual mode. In another embodiment, there is an E-Stop
system to disengage systems that cause the vehicle to move, such as the engine, while still leaving power in the systems that do not cause the vehicle to move. There is a method for autonomous mode starting of a vehicle, comprising receiving a
signal indicating autonomous mode, determining that a
parking brake lever is set and the brakes are engaged, disengaging the brakes while maintaining the lever in the set position, and engaging in autonomous mode. There is a safety
system with a mechanical bias to suppress moveable systems of the vehicle, comprising a
clutch that releases the mechanical bias to permit movement of the moveable
system when the
clutch is engaged. In another embodiment a system comprises a mechanical linkage with a restoration member that permits control of an operation system of the vehicle by a
remote operation member when the restoration member is engaged. There is also an
actuator that prohibits control of the operation system by the
remote operation member when the actuator is engaged.
