A PTO shaft driving device in a working machine, includes a parking switch to detect parking of a vehicle body, a first switch located on a manipulator located on the vehicle body to output a PTO shaft control command that is either a driving command to drive a PTO shaft located on the vehicle body or a stopping command to stop the PTO shaft, a second switch located at a position different from the manipulator to output a PTO shaft control command that is either a driving command to drive the PTO shaft or a stopping command to stop the PTO shaft, a first permission switch to selectively permit or prohibit a stationary work when the parking switch detects the parking, and a controller configured or programmed to control driving of the PTO shaft. The controller is configured or programmed to selectively drive or stop the PTO shaft according to the PTO shaft control command from the first switch or the second switch when the stationary work is permitted by the first permission switch.

Systems and methods of stopping propulsion of an electric vehicle in an emergency situation are provided. One method includes receiving a command to stop propulsion of the electric vehicle while the electric vehicle is in motion, and in response to the command, attempting to regulate an operation of an electric motor of the electric vehicle toward a no-load operating state of the electric motor while the electric vehicle is in motion. When the operation of the electric motor is outside a prescribed range of the no-load operating state after attempting to regulate the operation of the electric motor toward the no-load operating state, the method includes causing braking of the electric motor.

An engine control device for an industrial vehicle includes a seating detector configured to detect a seating state of a driver relative to a driver seat, a neutral detector configured to detect whether a direction operating member of the industrial vehicle is positioned in a neutral position, a fuel supply member configured to supply a fuel to the engine, a first controller configured to stop an output of a driving force from the engine when the seating detector detects that the driver is away from the driver seat, and a second controller configured to restart the output of the driving force from the engine in case that the seating detector detects that the driver is seated on the driver seat and the neutral detector detects that the direction operating member is positioned in the neutral position, after the first controller stops the output of the driving force from the engine.

The invention relates to a machine (1) for handling loads (24), comprising: —a wheeled chassis (2), —a drive system (3) for moving the wheeled chassis (2), —a load handling system (4) carried by the chassis (2), —a control unit (5), a device (6) for controlling the load handling system (4) that can be manually actuated by an operator, the control unit (5) being configured to receive control signals from said control device (6), a member (7) for activating the manually actuatable control device (6). The handling machine (1) comprises a sensor (8) of a parameter representative of a movement of the machine (1), and the control unit (5) is configured to allow the control of the handling system (4) with the control device (6) as a function of at least the parameter representative of a movement of the machine (1).

The present invention relates to an occupant monitoring method and apparatus therefor. A monitoring apparatus according to one aspect of the present invention may include a camera obtaining an image in a vehicle and a processor processing the image. Moreover, the processor may include a detecting module separating each region in which an object exists from the image, a classifying module classifying the object existing in the each separated region and a recognizing module recognizing a pose of an occupant if the object corresponds to the occupant.

A vehicle kill switch assembly includes a switch that is coupled to a vehicle. The switch is positioned beneath a driver's seat of the vehicle and the switch is electrically coupled to the ignition system of the vehicle. The ignition system is turned off when the switch is disengaged. A biasing unit is coupled to the vehicle and the driver's seat is coupled to the biasing unit. The biasing unit biases the driver's seat upwardly in the vehicle and the biasing unit is compressed when the driver sits in the driver's seat. The switch is engaged when the biasing unit is compressed to facilitate the vehicle to be driven. Conversely, the switch is disengaged when the biasing unit biases the driver's seat upwardly to inhibit the vehicle from being driven.

A working vehicle includes a prime mover, a driver's seat selectively set in either a first posture where a driver can sit thereon or a second posture where the driver cannot sit thereon, a speed controller to receive power from the prime mover and perform a speed-changing of the power, a PTO shaft to receive the speed-changed power from the speed controller, a posture switch to detect whether the driver's seat is set in the first or second posture, a parking switch to detect parking of a vehicle body, and a first actuator. During driving of the prime mover, the first actuator maintains the driving of the prime mover when both the parking and the driver's seat set in the second posture are detected, and stops the driving of the prime mover when neither the parking nor the driver's seat set in the second posture is detected.
