A control system for a vehicle uses one or more inputs of a velocity request, a brake request, a speed request, travel direction indication, engine speed, and vehicle speed to determine a control strategy for a continuously variable transmission. A target engine speed is selected based upon the inputs, and the engine and continuously variable transmission ratio are controlled to achieve the target engine speed while controlling the vehicle according to the inputs. In some embodiments, the control strategy further selects the target engine speed according to accessory system demands, such as a hoist or lift system.

Controlling a maximum vehicle speed for an industrial vehicle includes determining, by a processor of the industrial vehicle, a torque applied to the traction wheel of the industrial vehicle; converting the torque to an equivalent force value; and determining an acceleration of the industrial vehicle while the torque is applied to the traction wheel. Additional steps include calculating a load being moved by the industrial vehicle, based at least in part on the acceleration and the equivalent force value; and controlling the maximum speed of the industrial vehicle based on the calculated load being moved by the industrial vehicle.

A vehicle includes a vehicle controller communicating over a first communication system with actuators for changing the state of vehicle systems. A signal module communicates with the vehicle controller via the first communication system. One or more signal sources communicate with the signal module via a second communication system, and transmit signals to the signal module. Based on one or more signals and one or more user inputs, the signal module generates and transmits control signals to the vehicle controller. The vehicle controller actuates the actuator based on the control signal.

A vehicle-initiated cadenced operator interaction system introduces an operational concept to a vehicle operator via a machine-initiated interaction. Thereafter, interaction is initiated by the industrial vehicle according to a cadence that provides a gap between interactions so that the operator can demonstrate the behavior associated with the introduced concept. Industrial vehicle data associated with the content of the interaction(s) is analyzed and evaluated against pre-defined operational criteria to determine whether the operator is demonstrating the appropriate skill/behavior associated with the interaction(s). Responsive to the operator's demonstrated ability, the system can modify operation of the vehicle to tune the industrial vehicle to the operator. The system can also extend to the operating environment, by interacting with electronic devices, vehicles, machines, etc., in the operating environment to tune the environment to the operator.

An industrial vehicle includes an object detector configured to detect a position of an object, a notification unit configured to perform notification, a controller configured to control the notification unit according to the position of the object, and an intention-of-starting detector configured to detect whether an operator of the industrial vehicle has an intention of starting the industrial vehicle. The controller stops the notification by the notification unit when the intention-of-starting detector does not detect the intention of starting. The controller permits the notification by the notification unit when the intention-of-starting detector detects the intention of starting.

A method and system of controlling a work machine having an object detection system. The method comprises capturing an image with a camera and then recognizing an object in the image with the object detection. In next steps, the method includes defining the recognized object as a target object and operating the work machine wherein the object detection system is configured to execute a function of the work machine when the object is recognized. Finally, the method includes overriding the execution of the function of the object detection system when the object is defined as the target object.

A wheel load estimation device includes an obtaining unit obtaining angular velocities and angular accelerations of a rigid body including an element, accelerations of the rigid body in a front-rear direction and in a lateral direction, a weight of the element, and a position including a height of the element. The element fluctuates a center of gravity of the rigid body.

A wheel load variation calculation unit calculates variation amounts of wheel loads that each act on a corresponding one of a plurality of wheels supporting the rigid body. A wheel load estimation unit estimates the wheel loads.

An obstacle notification device includes an obstacle detection unit configured to detect a positional relationship between an industrial vehicle and an obstacle, a display unit, and processing circuitry. The processing circuitry displays an image for notifying an operator of the presence of the obstacle on the display unit, and executes at least one of restriction of traveling of the industrial vehicle and warning when the obstacle is a causal obstacle meeting a specific condition. The processing circuitry displays a first image on the display unit when notifying the operator of the presence of an obstacle different from the causal obstacle, and displays a second image that is different from the first image on the display unit when notifying the operator of the presence of the causal obstacle.
