| 20100056337 | Cruise Control System for Motor Vehicles - A cruise control system for motor vehicles controls the vehicle speed to a preset desired speed. The cruise control system includes an operating unit for switching the cruise control on and off, an accelerator pedal, normally present in the vehicle, for activating the cruise control and for presetting the desired speed, and a brake pedal, also normally present in the vehicle, for interrupting the active cruise control. The operating unit is configured as a single operating element, during whose actuation the cruise control is switched on or off as a function of the actual operating condition of the cruise control system. | 03-04-2010 |
| 20100100281 | Cruise Controller for Motor Vehicles and Method of Operating Same - A cruise controller and method are provided for motor vehicles for the purpose of adjusting the vehicle speed on the basis of a predefined setpoint speed. The cruise controller includes a monitoring device, which is designed to evaluate the vehicle state variables steering wheel angle, lateral acceleration, and/or yaw rate. If one of the evaluated vehicle state variables exceeds a predefined first vehicle state variable limit value, the cruise control function is switched into a standby mode. | 04-22-2010 |
| 20100114450 | Method for Reactivating Operation of a Cruise Control System That Had Been Interrupted - A method for reactivating an interrupted cruise control function of a cruise control system of a vehicle is provided. When the vehicle is not in the stationary state, in order to allow the driver to reactivate intuitively the interrupted cruise control function, the driver may reactivate the interrupted cruise control function by actuating a gas pedal of the vehicle. | 05-06-2010 |
