An electromagnetic levitation force type propulsion device includes an integrated electromagnet structure, an auxiliary propulsion structure and a power supply control structure. The integrated electromagnet structure includes a mounting frame, a propulsion outputting shaft capable of moving back and forth relative to the mounting frame and extending out of the mounting frame, and two electromagnets opposite to each other. One of the electromagnets is assembled to the mounting frame to form a stationary electromagnet and the other electromagnet is fastened to the propulsion outputting shaft to form a movable electromagnet. The movable electromagnet is provided at the other side of the mounting frame and can move back and forth relative to the stationary electromagnet. The auxiliary propulsion structure drives the movable electromagnet back and forth relative to the stationary electromagnet. The power supply control structure provides a power supply for the integrated electromagnet structure and/or the auxiliary propulsion structure.

Various embodiments provide for platooning control via accurate synchronization that will not result in string instability. Some embodiments provide a distributed control scheme for platoon motion control that provides a decentralized implementation of the leader information controller. These control techniques are able to manage the performance of the string of vehicles by maintaining a desired spacing distance between any two successive vehicles in the presence of communications induced delays. In order to regulate the spacing between a vehicle and its predecessor in the string, every vehicle (with the exception of the leader vehicle) uses the relative distance from itself to its predecessor (e.g., as measured using a laser ranging sensor) and a control signal of the predecessor (e.g., received via a wireless link). Various embodiments are capable of dealing with non-homogeneous strings of vehicles and non identical controllers for each vehicle in the string.

A work vehicle including: a hydraulic stepless transmission that shifts a speed of a driving force from an engine; a gear shift pedal that performs an acceleration/deceleration operation of a shifted output from the hydraulic stepless transmission; a control section that controls the engine and the hydraulic stepless transmission based on an operation amount of the gear shift pedal; and acceleration/deceleration switches that increase and reduce a vehicle speed in performing an auto-cruise mode. The control section stores a set maximum vehicle speed. In a case where the acceleration/deceleration switches are operated in the auto-cruise mode, the control section increases and reduces the vehicle speed stored in shifting to the auto-cruise mode based on the amount of change in accordance with the maximum vehicle speed.

A vehicular driving assist system includes a forward-viewing camera and a side object detection system disposed at a vehicle equipped with the vehicular driving assist system. The side object detection system includes a driver side-sensing radar sensor and a passenger side-sensing radar sensor. Image data captured by the forward-viewing camera is processed to detect traffic lane markers for a lane departure warning system of the equipped vehicle. Responsive at least in part to one of the radar sensors detecting a vehicle travelling in the same direction as the equipped vehicle and approaching from rearward of the equipped vehicle in a traffic lane that is to the respective side of the traffic lane that the equipped vehicle is travelling in, the vehicular driving assist system alerts a driver of the equipped vehicle of presence of the detected vehicle regardless of turn signal usage by the driver of the equipped vehicle.

In one aspect, a system for regulating the operating distance defined between work vehicles during the performance of field operations may include a sensor configured to emit an output signal for reflection off of a component of a first work vehicle or a second work vehicle and detect the reflected output signal as a return signal. A controller of the system may be configured to monitor an operating distance between the first and second work vehicles within the field based on data received from the sensor associated with at least one of the output signal or the return signal. Additionally, the controller may be configured to initiate a control action associated with adjusting a relative positioning between the first and second work vehicles within the field when it is determined that the monitored operating distance has fallen outside the predetermined operating distance range.

A cruise control device has a white line recognition unit recognizing a white line defining a lane having the own vehicle, based on an image captured by an image capturing device and a lane entering and leaving determination unit carrying out lane entering determination and lane leaving determination of the own vehicle with respect to a preceding vehicle traveling ahead of the own vehicle based on the relative position of the own vehicle in the vehicle width direction with respect to the white line. In the lane entering determination and lane leaving determination, a preceding vehicle on the lane to which the own vehicle is moving is determined to be an entering lane vehicle whose lane the own vehicle is entering, and a preceding vehicle on the lane from which the own vehicle is moving is determined to be a leaving lane vehicle whose lane the own vehicle is leaving.

This vehicle control device includes: a distance measurement unit that measures the distance between a vehicle and a preceding vehicle; and an engine control unit that starts up an engine when, in comparison to a distance measured by the distance measurement unit once a host vehicle has stopped and an engine mounted in the host vehicle has stopped, a distance newly measured by the distance measurement unit increases by at least an offset amount that indicates the amount of increase in distance used to determine whether to start up the engine.

A travel control device assists automatic traveling of a vehicle by controlling a target vehicle speed, which is a target value of an actual vehicle speed, when making the vehicle travel to a target point. The travel control device includes a setting unit for executing a setting process for setting the course of the target vehicle speed until the vehicle reaches the target point, based on the actual vehicle speed and the target point. If a request to change the vehicle speed occurs during execution of the automatic traveling and the actual vehicle speed is changed based on the request, the setting unit executes a resetting process for resetting the course of the target vehicle speed, based on the actual vehicle speed when the request is canceled and a remaining distance from a position of the vehicle when the request is canceled to the target point.
