Method for operating a motor vehicle and motor vehicle

Abstract

The invention relates to a method for operating a motor vehicle (1) comprising: a navigation system (2) and a speed regulation device (3), the navigation system having at least one stored Distance information, the speed adjustment device adjusts the actual speed of the motor vehicle (1) to the stored distance information determined based on the stored distance information by controlling the driving device (5) or braking device (6) of the motor vehicle (1) The theoretical speed of the said navigation system (2) is supplied with at least one information about the changed route of the changed route, and the speed regulation device (3) adjusts the actual speed of the motor vehicle (1) or to A stored setpoint speed determined on the basis of stored distance information or an adjustment to a changed setpoint speed determined on the basis of changed distance information, with the aid of this evaluation parameter for a temporally earlier passage of the changed distance section (15) Make an assessment.

Description

technical field [0001] The invention relates to a method for operating a motor vehicle, the motor vehicle comprising a navigation system with at least one stored route information describing a route section, and a speed regulation device via which the speed regulation device The drive or braking device of the motor vehicle is controlled to adjust the actual speed of the motor vehicle to a stored setpoint speed determined on the basis of the stored distance information. Background technique [0002] Driver assistance systems are known which assist the driver of the motor vehicle in following the permissible maximum speed for the route segment or regulating the actual speed of the motor vehicle to the permissible maximum speed. In this case, the driver can specify a setpoint speed of the motor vehicle, to which the actual speed of the motor vehicle is set. Furthermore, various systems are known which regulate the actual speed of the motor vehicle on the basis of a suitable ch...

AI Technical Summary

Problems solved by technology

The above situation may be unfavorable in certain situations, because some influencing factors cannot be known only by the course of the road or the turning radius

For example no information is given about how wide the road is, how well visible the road is, or whether there are other potential hazards e.g. due to road structure at the edge of the lane

[0004] Furthermore, it is disadvantageous with the systems known from the prior art that when new route information is given, for example a new navigation map, changed route information must be disclosed for the speed control device

For this purpose, the changed route must usually be traversed by reference travel in order to disclose the route, which is complicated
