Embodiment Construction

[0035] refer to figure 1 with image 3 , the device 1 for assisting driving on a roadway according to the first embodiment of the invention is intended to be incorporated in a motor vehicle 4 moving on a roadway 6 . Auxiliary equipment 1 in figure 1 China-Israel box figure 2 Schematically illustrated, the block diagram shows the position control of a vehicle 4 in a roadway 6 .

[0036] The roadway 6 is bounded laterally by two boundaries 8 and 10 . In the example shown, boundaries 8 and 10 are white dashed lines made on the road. However, consideration of other examples of roadway boundaries (eg solid lines, curbs, or even reflective markings such as Bott points) clearly does not depart from the scope of the present invention. Vehicle 4 includes a steering system 12 . Alternatively, the vehicle comprises several steering systems, as in the case of vehicles equipped with four-wheel steering.

[0037] refer to figure 1 , in the box figure 2 The steering system 12 is s...

Abstract

An assistance device (1) for driving in a traffic lane (6) for a motor vehicle (4) includes a module (14) for determining at least one input variable chosen from among variables related to the vehicleand variables related to the traffic lane, a module for producing (20) a correction instruction ([alpha]ijk) according to the input variable, and an assistance module (22) capable of implementing a driving assistance action according to the correction instruction ([alpha]ijk). Said input variable includes a lateral position (y4 / 6) of the vehicle (4) in the traffic lane (6) and a lateral deflection speed (V4 / 6) of the vehicle (4).

Description

technical field [0001] The invention relates to the field of driving assistance devices for motor vehicles on a roadway, and more particularly to devices for keeping or centering a vehicle in its roadway. Background technique [0002] Today, driver assistance devices for motor vehicles on roadways are known in the prior art. For example, a device for keeping a motor vehicle in a roadway is often referred to as "Lane Keeping Assist" or the corresponding abbreviation "LKA". Likewise, a device for centering a motor vehicle in its lane is often referred to as "Lane Centering Assist" or the corresponding abbreviation "LCA". [0003] Such systems are usually integrated in the vehicle computer and are in data communication with cameras and network controllers. A network controller is a conventional computer incorporated in the vehicle and is more commonly known as a "Controller Area Network" or the corresponding abbreviation "CAN". A driver assistance device integrated in this w...
