Motor vehicle managing method, involves activating function e.g. security function such as anti-accident function according to vehicle displacement speed and plot of trip as vehicle travels along predefined route set by navigation system

摘要

The method involves calculating a characteristic value of movement of a vehicle (1) along a predefined plot of a trip according to speed of actual displacement and the plot. A function e.g. security function such as anti-accident function, of the vehicle is activated based on the value. The anti-accident function is activated under a regulation form reducing the speed of displacement. The method involves activating a safety function, in particular an accident-prevention function, e.g. 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. The method can also activate a driver information function, e.g. in the form of feedback regarding a forthcoming, critical curve, 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. The method also provides information 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, and which 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.
