The control unit is further programmed to, based on the registered first and second parameters, adjust as set vehicle overspeed for a brake cruise control in the cruise control to a new value. A vehicle speed increase resulting in a vehicle speed that exceeds due to delays in the cruise control and braking devices can be avoided.11-08-2012
20120290185SCHEDULING SYSTEM AND METHOD FOR A TRANSPORTATION NETWORK - A system is provided that includes a control unit configured to be disposed on-board at least one of a first vehicle or a second vehicle. The control unit also is configured to receive an updated time of an event involving the first vehicle and the second vehicle traveling in a transportation network. The control unit also is configured to change a speed of said at least one of the first vehicle or the second vehicle in response to the updated time to arrive at the event. A method is provided that includes, at one of a first vehicle or a second vehicle, receiving an updated time of an event involving the first vehicle and the second vehicle in a transportation network. The method also includes changing a speed of said one of the first vehicle or the second vehicle in response to the updated tune to arrive at the event.11-15-2012
20120029785Method for Determining the Wheel Pressure in an Electronically Actuable Motor Vehicle Brake Control System - A method is described in which the wheel pressure in an electronically controlled motor vehicle brake system is determined. The brake system includes inlet valves and outlet valves in the wheel circuits. At least one of the valves allows adjusting the valve current. The basis for this are previously determined calibration values which describe the opening current behavior of the outlet valve. A verification of the wheel pressure is performed during a wheel pressure control operation by briefly opening the outlet valve of one brake circuit. The current prevailing in this case can be taken into account as an indicator for determining the wheel pressure.02-02-2012
20130197773DESCENT CONTROL OF VEHICLE SPEED - The present disclosure provides a method of automatically controlling ground speed of a vehicle in which the vehicle includes a control system having a controller, a throttle, a brake sensor, and a braking mechanism. The method includes enabling a descent control function in the controller, detecting a change in a vehicle operating condition, determining current vehicle ground speed, establishing a desired vehicle speed based on the current vehicle ground speed, and controlling the braking mechanism to maintain vehicle ground speed at or below the desired vehicle speed.08-01-2013
