The present invention comprises: a synchronization start determination unit 110 for determining a synchronization start of a synchronization device 70; a half-clutch determination unit 130 for determining whether a clutch device 20 is in a half-clutch state where the clutch device has not been switched from a connection state to a disconnection state; and a damage determination unit 140 which, when the synchronization start determination unit 110 has determined the synchronization start and if the half-cutch determination unit 130 has determined a half-clutch state, determines that damage is applied to the synchronization device 70 caused by the differential rotation between the power transmitted from a driving force source 10 side via the clutch device 20 and the power transmitted from a driving wheels 16L, 16R side.

A steering apparatus of a smart mobility vehicle includes: a cockpit module disposed in front of a driver seat and a passenger seat within a vehicle; a steering wheel part connected to the cockpit module, and switchable between a position toward the driver seat and a position toward the passenger seat in a longitudinal direction of the cockpit module; and a locking part to fix the steering part according to a preset condition. The cockpit module includes a first flat section disposed in front of the driver seat and a second flat section disposed in front of the passenger seat; and a locking section curved upward to connect the first flat section and the second flat section.

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.

A system and method for compensating reduced track speed because of engine droop for a work machine is disclosed. The system may comprise a frame, an attachment coupled to the frame, a ground-engaging mechanism adapted to support the frame, an engine, a motor, a track speed sensor, an engine speed sensor, and a controller. The engine may drive the ground-engaging mechanism and attachment. The engine may be coupled through a variable speed transmission to the ground-engaging mechanism and the attachment. They variable speed transmission may include a hydrostatic circuit. The controller may be adapted to send an increased transmission command signal based on a drop in the engine speed signal when the work machine engages an increased load. The increased transmission command signal may increase a motor speed to cause an increase in track speed to compensate at least a portion of the reduced track speed from the engine speed droop.

A vehicle corner module (VCM) is provided for regulating motion of a host vehicle which comprises a vehicle-onboard vehicle-controller. The VCM comprises a sub-frame mountable to a reference frame of the host vehicle; a wheel-hub assembly comprising a wheel-hub; VCM-sub-systems mediating between the sub-frame and the wheel-hub assembly, e.g., a drive subsystem, a steering subsystem, a suspension subsystem and/or a braking subsystem; and an VCM-onboard VCM-controller, comprising one or more processors and a computer-readable medium storing program instructions that, when executed by the one or more processors, cause the one or more processors to establish a communication link with a vehicle-controller, including electronically transferring information about the VCM from the VCM-controller to the vehicle-controller, and to perform, in response to an installation of the VCM on a vehicle, a post-installation validation-process that includes validating the VCM-subsystems and communicating a result of the validating to the vehicle-controller.

A four-wheel drive vehicle includes: a drive-power distribution device for distributing a drive power from an engine to main and auxiliary drive wheels with a drive-power distribution ratio between the main drive wheels and auxiliary drive wheels; and a control apparatus for controlling an electric motor such that the drive-power distribution ratio becomes a target distribution ratio value, by setting an electric-current command value for driving an electric motor. The control apparatus is configured, in a drive-power transmitted state in which the drive power is transmitted to the drive-power distribution device, to execute a command-value reduction control operation for causing the electric motor to be driven with the electric-current command value being set to a value smaller than in a drive-power non-transmitted state in which the drive power is not being transmitted to the drive-power distribution device.
