Embodiment Construction

[0033] figure 1 A road 2 is shown on which a motor vehicle 4 is traveling.

[0034] A motor vehicle 6 driving ahead is driving ahead of the motor vehicle 4 . Motor vehicle 6 driving ahead accelerates and becomes faster than motor vehicle 4 , which is indicated by the correspondingly different length arrows on motor vehicles 4 , 6 . The distance D between the motor vehicles 4 , 6 increases, which is greater than the setpoint distance Ds to be maintained by the distance control system 7 of the motor vehicle 4 .

[0035] On the road 2 there is a curve 8 . The curve 8 has a radius of curvature R, which is measured in the present embodiment from the center of the curve to the middle of the roadway 2.1. The distance regulation system 7 of motor vehicle 4 (in figure 2 (described in more detail in ) includes a route detection device, by means of which the course of the road on the road 2 can be determined. This detection can occur continuously. With the aid of the route detection...

Abstract

The present invention relates to a distance control system (7) for automatically adjusting a distance (Ds) between a motor vehicle (4) and a motor vehicle (6) traveling ahead of the vehicle (4). The distance control system (7) has at least one sensor (10) for detecting the distance (D) with respect to the vehicle (6) traveling ahead. A route detecting device (18) for detecting a front road (8) is also arranged. The distance control system (7) also has a control device (12) for transmitting an acceleration command to a driver (17) of the motor vehicle (4) to perform acceleration at a preset accelerated speed (A1) when the distance (D) with respect to the preceding vehicle (6) is increased or in free straight driving; and determining an expected lateral accelerated speed (Aq) and adjusts the longitudinal accelerated speed (Al) according to the expected lateral accelerated speed (Aq) when the route detecting device (18) recognizes a front curve. The invention also relates to the corresponding motor vehicle (4) and to a corresponding computer program product.

Description

technical field [0001] The invention relates to a distance control system, a motor vehicle and a computer program product. The distance control system is used to automatically adjust the distance of a motor vehicle to a motor vehicle driving ahead. Background technique [0002] Distance control systems of the type mentioned at the outset are known in the prior art. Corresponding distance-regulated systems are generally also referred to as distance-regulated speed controllers. Known systems measure the distance to a motor vehicle driving ahead and keep the motor vehicle equipped with the distance control system at a certain distance from the motor vehicle driving ahead. This distance will be related to speed. If the motor vehicle driving ahead leaves there and thereby increases the distance between the two motor vehicles, the distance control system accelerates the motor vehicle with a predetermined acceleration. This acceleration is maintained until the preset speed is r...
