A device for the steering assistance of a vehicle combination of a towing vehicle and an attached implement in which the attached implement swivels at a rear coupling point of the towing vehicle. The implement includes wheels that are arranged on opposite sides, which can be acted on by the control of corresponding individual wheel drives, independently of one another, with a drive torque. An electronic control unit applies a yawing moment to the implement by the asymmetrical control of the individual wheel drives in such a way that a transverse force exerted on the towing vehicle through the rear coupling point, builds up in the sense of the attainment of a pre-specified steering behavior of the vehicle combination.

A travelling apparatus including a controller that adds, when receiving a turning instruction, a first correction amount calculated based on rider's centroid information to a first rotation amount of a first driving wheel calculated based on the turning instruction to rotationally drive the first driving wheel and adds a second correction amount calculated based on rider's centroid information to a second rotation amount of a second driving wheel calculated based on the turning instruction to rotationally drive the second driving wheel is provided.

A riding lawn care vehicle (10) includes first and second drive wheels (32), a steering lever (34), a brake assembly (110), and a mechanical brake linkage assembly (120) including a cable tensioner (250). The brake assembly (110) may be operably coupled to at least one of the first and second drive wheels (32) to enable brakes to be selectively applied to the first and second drive wheels (32) based on a position of the steering lever (34). The cable tensioner (250) may be configured to activate the brake assembly (110) relative to the at least one of the first and second drive wheels (32) in response to the steering lever (34) being moved outwardly to an outboard position. The mechanical linkage assembly (120) may be configured to provide a greater amount of rotation of the cable tensioner (250) than a magnitude of rotation of the steering lever (34) when the steering lever (34) is moved from the inboard position to the outboard position.

Various embodiments of the present invention are generally directed to a systems and methods for assessing turns made by one or more vehicles. According to various embodiments, the system is configured to identify, based telematics data captured from the vehicles, turns executed by the vehicle during a particular time period. The system is further configured to analyze the identified turns to determine and display various turn segment attributes to a user in order to provide an indication of turns having an abnormal or excessive duration and/or to provide overall efficiency-indicative information relating to the vehicle turns.

A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. Each driven wheels is driven by a hydraulic motor with a continuous adjustment of the motor displacement, with the motor being driven by a pump also having continuous displacement. The motor displacement is controlled by an electronic controller in response to stroking of the speed control lever to manage the displacement to provide required drive torques at different points in the stroke. There is provided an automatic steering system having a guidance controller arranged to receive GPS position information which controls the steering by differentially adjusting the displacement of the motors so that the automatic steering is independent of the manual steering which controls the pumps.

An electric steering device includes an electric actuator which generates a steering assist force for a steering mechanism of a vehicle, a control unit which controls the steering assist force generated from the electric actuator based on an operation of a steering wheel by a driver, an ignition signal detection unit which detects presence or absence of an ignition signal of the vehicle, and a speed acquisition unit which acquires a running speed of the vehicle. In a case that the ignition signal is not detected and the running speed is a predetermined speed or more, the control unit reduces an upper limit of the steering assist force generated from the electric actuator so as to be smaller than an upper limit in a case that the ignition signal is detected.

A control system for a work vehicle includes an acceleration detection device and a controller. The acceleration detection device detects an acceleration of the work vehicle. The controller determines whether the acceleration is greater than a first threshold and reduces the a vehicle speed when the acceleration continues to be equal to or greater than the first threshold over a predetermined first determination time period.

A two-wheel, self-balancing vehicle is disclosed. In one aspect, the two-wheel, self-balancing vehicle comprises a first wheel and a second wheel, the first wheel and the second wheel being spaced apart and substantially parallel to one another. The two-wheel, self-balancing vehicle further comprises a foot placement section connecting the first wheel and the second wheel. The two-wheel, self-balancing vehicle further comprises a set of position sensors in the foot placement section, the set of position sensors configured to generate inclination angle signals and velocity signals of the two-wheel, self-balancing vehicle. The two-wheel, self-balancing vehicle further comprises a first gravity sensor and a second gravity sensor in the foot placement section, the first gravity sensor and the second gravity sensor configured to generate weight signals and gravity angle signals. In addition, the two-wheel, self-balancing vehicle comprises a control logic configured to output control signals that control the movement of the two-wheel, self-balancing vehicle in response to the inclination angle signals, the velocity signals, the weight signals, and the gravity angle signals.

A working machine includes a controller configured or programmed to perform an automatic deceleration for automatically decelerating a left traveling motor and a right traveling motor rotated at a second speed by shifting from the second speed to the first speed, and to determine a deceleration threshold that is used for judging whether the automatic deceleration has to be performed or not.
