A method is provided for alternately triggering driving states of a utility vehicle. The method includes providing a control element and a transmission selectively engageable in a forward driving state (F) for forward travel of the utility vehicle, a reverse driving state (R) for reverse travel, and a standstill driving state (S) for a stationary output of the transmission without disconnection of the drivetrain in the utility vehicle. The method further includes operating the transmission in a current driving state, operably selecting a target driving state while operating in the current driving state, and controllably triggering the transmission to the standstill driving state before shifting the transmission to the target driving state.

A traveling work vehicle includes a gear-shifting control unit that outputs a gear-shifting control command to a main gear-shifting apparatus for shifting gears without cutting off power transmission, a sub gear-shifting apparatus for shifting gears by cutting off power transmission, and a first operation unit and a second operation unit that provide gear-shifting, upshifting or downshifting, operation commands to the gear-shifting control unit. The gear-shifting control unit has a first travel control section that generates a gear-shifting control command for shifting gears in the main gear-shifting apparatus in response to the gear-shifting operation command from the first operation unit in a work traveling mode, and a second travel control section that generates a gear-shifting control command for shifting gears in the sub gear-shifting apparatus in response to the gear-shifting operation command from the second operation unit in the work traveling mode.

A drive system and remote control for a light electric vehicle. The drive system includes a power unit, a main gearing connected to the power unit and a remote control connect to the power unit. The power unit includes an assist motor arranged to provide torque output to a torsion shaft of the light electric vehicle, and a control motor arranged to adjust transmission ration of the main gearing. The remote control further includes an operating switch arranged to switch the remote control between a first and a second operating state for controlling the assist motor and control motor, respectively.

The invention relates to a rotary control device for a vehicle comprising a user interface surface, in particular a knob, that is embodied to rotate with respect to a housing of the device around a rotational axis of the device, further comprising a sensor unit for monitoring the orientation and/or rotational movement of the user interface surface with respect to the housing, a processing unit, and a communications interface for transmitting control signals according to an output from the processing unit, said output being generated by the processing unit on the basis of sensor data from the sensor unit.

A control unit is provided for an automatic transmission of a vehicle. The vehicle has a gear selection operating element which allows a user of the vehicle to set different gear stages of the transmission by actuating the gear selection operating element, and the vehicle has at least one setting operating element which allows the user to change the value of a parameter of a function of the vehicle by actuating the setting operating element when the function of the vehicle is activated. The control unit is designed to detect an actuation of the gear selection operating element for a period of time which is equal to or longer than a minimum duration and to determine that the function of the vehicle is deactivated. In response thereto, the control unit is additionally designed to allow a manual change of the transmission gear by actuating the at least one setting operating element.

The invention relates to an arrangement for reading off predetermined positions of a gear lever (11). A sensor arrangement (1) with a first sensor component (10) moves with the gear lever (11) and a plurality of second sensor components (S21-S25) interacts with the first sensor component (10), wherein in each of the predetermined positions of the gear lever (11), the first sensor component (10) interacts with at least one second sensor component (S21-S25). A position determination unit (30) compares the current sensor output values with stored sensor output values in a table (40). When a faulty condition is detected in one of the sensor components (S21-S25), the stored sensor output values for the faulty sensor component are updated with the faulty output value of the faulty sensor component in the table (40) of expected sensor output values.

A working machine includes a machine body, a prime mover, a traveling device mounted on the machine body, a traveling motor to provide a power to the traveling device and to switch between a first speed and a second speed higher than the first speed, a traveling pump to be driven by the prime mover and to supply operation fluid to the traveling motor, and a controller device including an automatic shifter to automatically shift the traveling motor to the first speed or to the second speed, a timer to count an elapsed time from the automatically shifting, and a shift prohibitor to prohibit the automatically shifting by the automatic shifter when the elapsed time counted by the timer is less than a threshold.
