A method for shifting a transmission in a machine. The method includes detecting a request for a directional shift of the transmission and determining a ground speed of the machine in response to the request. The method further includes overriding the request if the ground speed is above a ground speed threshold. Further, the method includes preparing the machine for the directional shift by limiting an output speed of a power source of the machine and by issuing a command to a brake unit of the machine to reduce the ground speed of the machine. Furthermore, the method includes validating and raising the request to the transmission to execute the directional shift if the ground speed is below the ground speed threshold.

The present invention prevents occurrence of abnormal noise and swing of a vehicle in mitigating braking force of a steered wheel while reducing a steering load at the time of stationary steering to reduce a burden of a steering device and reducing stress accumulation due to stationary steering to reduce burdens of a tire, a suspension device and the steering device. The present invention includes a stop braking force control unit 202 that individually controls braking forces of steered wheels 51 and 52 and non-steered wheels 53 and 54 at the time of deceleration of the vehicle, and a pre-detection unit 203 that detects steering in a stopped state of the vehicle in advance, in which the stop braking force control unit executes, when the steering in a stopped state of the vehicle is detected in advance by the pre-detection unit, braking force mitigation control to decrease the braking forces of the steered wheels to be lower than the braking forces at the time of normal braking.

A method of controlling a mobile work machine having a reversing gearbox. The driving direction reversal is initiated by detecting a driving direction reversal command. A change of the torque transmission from a current driving direction to a new driving direction is carried out as a powershift. Braking for the driving direction reversal occurs in a manner so as to recuperate energy. Furthermore, a device for controlling a mobile work machine, in particular for implementing the method, is also disclosed.

When a vehicle control interface receives information indicating “Forward” from a VP, the vehicle control interface sets a value 0 in a signal indicating a rotation direction of a wheel. When the vehicle control interface receives information indicating “Reverse” from the VP, the vehicle control interface sets a value 1 in the signal indicating the rotation direction of the wheel. When the vehicle control interface receives information indicating “Invalid value” from the VP, the vehicle control interface sets a value 3 in the signal indicating the rotation direction of the wheel. The vehicle control interface provides the signal indicating the rotation direction of the wheel to an ADK.

A motor vehicle for operation by a driver has a frame with wheels and a motor connected to the frame. A steering control is connected to the wheels to establish a steering angle. A controller is operably connected to the steering control, to the motor, and to the wheels, and is operable to selectably drive the wheels in a forward direction in a drive mode and in a rearward direction in a reverse mode. The controller is operable to select a direction for driving the wheels in response to a pattern of steering angle movements, without operator indication of a direction.

In various embodiments, a system and method for determining a gross combined weight of a vehicle and its load is disclosed. A method includes: providing predetermined calibration settings relating force to engine speed for a specific vehicle travelling in a reverse direction, altering accelerometer data based on filtered vehicle pitch and roll data, determining that one or more vehicle performance parameters fall within a threshold range, storing a plurality of data pairs that include longitudinal acceleration and drive force, and determining a slope of a line that linearly approximates the plurality of data pairs, the slope indicating a total weight, the total weight comprising a weight of the vehicle and a weight being hauled by the vehicle; and transmitting the total weight to a remote system for display.
