Method for operating a vehicleMethod for operating a vehicle description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090177360, Method for operating a vehicle. Brief Patent Description - Full Patent Description - Patent Application Claims
This application is a continuation of prior application U.S. Ser. No. 10/896,184 filed Jul. 21, 2004, which claimed priority to German Patent Application No. 103 33 962.0, which was filed in Germany on Jul. 25, 2003, and which is hereby incorporated by reference in its entirety. The present invention concerns a method for operating a vehicle. There are methods for operating a vehicle, in which a route is predefined by a navigation device, and in which the vehicle moves on the predefined route at a current traveling velocity. The exemplary method of the present invention for operating a vehicle may have the advantage that a value characteristic of the vehicle movement along the predefined route is precalculated as a function of the current traveling velocity and the predefined route, and that a vehicle function is activated as a function of this value. In this manner, a safety function may be activated when the predicted vehicle movement represents a safety risk. In addition, information as to how the driver of the vehicle should drive the vehicle as economically and/or safely as possible, based on the expected vehicle movement, may be generated for or transmitted to him. Consequently, the driving safety may be increased and the fuel consumption may be reduced, and a better or more effective exhaust-gas composition may also be attained. It may be advantageous when a safety function, in particular an accident-prevention function, which may be in the form of a traveling-velocity limitation system, a function for occupant protection, which may provide precharging of the brake system or conditioning of at least one restraint system, or a driver-information function, which may be in the form of feedback regarding a forthcoming, critical curve, is activated as a vehicle function. In this manner, a safety risk derived from the predicted vehicle movement may be more easily or effectively minimized or reduced beforehand. In addition, it may be advantageous when a function relating to vehicle operation, in particular along the lines of optimizing fuel consumption or exhaust-gas composition, which may be within the scope of feedback regarding the fuel consumption or exhaust gas, is activated as a vehicle function. In this manner, an optimum fuel consumption or an optimum exhaust-gas composition may be produced for a predicted vehicle movement. It may be advantageous that when the feedback is carried out or performed haptically, in particular at an accelerator pedal. In this manner, it may be ensured that the driver also senses the feedback and can initiate proper measures, for example, completely releasing the accelerator pedal. An additional advantage may be provided when a yaw rate is selected as a characteristic value for the vehicle movement along the predefined route. The yaw rate represents a reliable value, in particularly for cornering, the driving safety to be expected for the predefined route and the current traveling velocity being able to be quantified with the aid of this value. It may also be advantageous when it is assumed that, during the calculation of the characteristic value, an accelerator pedal of the vehicle is not operated. In this manner, the safety risk may be deduced from the vehicle movement predicted by the current thrust of the vehicle and the predefined route alone, which means that a safety risk is also detected when the driver is no longer accelerating at all. A further advantage may be provided when the route of the vehicle is predetermined, in particular by a navigation system, in the form of a set of route points, and when the path between the route points is interpolated with the aid of continuous and differentiable functions. First of all, this allows the predefined route of the vehicle to be approximated in a particularly simple and complete manner, and secondly, the characteristic value for the expected vehicle movement may be derived from this predefined route with the aid of mathematical functions. A further advantage may be provided when the characteristic value is determined as a function of a steering angle, and when the steering angle is determined as a function of a traveling-direction vector and a vector tangent to the traveling direction. In this manner, the characteristic value may take into account the windiness of the predefined route in a particularly reliable manner. A further advantage may be provided when the traveling-direction vector is determined as a function of a radian measure of the predefined route, and when the radian measure is determined from a range of the vehicle. In this manner, the travel-direction vector may be ascertained with the aid of mathematical relationships. A further advantage may be provided when the range of the vehicle is ascertained as a function of a vehicle acceleration, and when the vehicle acceleration is ascertained with the aid of a pulling-force equation. In this manner, the range of the vehicle may also be determined in a particularly simple and reliable manner with the aid of mathematical and physical relationships.
