Speed Control System and Method Having a Distance Sensor, Intended for a Motor Vehicle

Принадлежит: Bayerische Motoren Werke AG

A motor vehicle speed control system having a distance sensor operates in a first mode when the vehicle is traveling on a clear stretch of road in which a predetermined desired vehicle speed is set. In a second mode when the vehicle is following another vehicle, a predetermined minimum distance from a selected target object is set. The target object is selected by a first selection process that screens out stationary objects. When a defined condition prevails, the first mode switches into a third mode in the form of deceleration, wherein a second selection process is started which also evaluates stationary target objects. Until a target object is selected, the vehicle travels on a clear road with deceleration initiated which is reduced relative to following another vehicle. If a target object is selected by the second selection process, the system switches over without delay from the third mode into the second mode.

Vehicles feature various forms of automated driving control, such as speed control and braking distance monitoring. However, the parameters of automated control may conflict with the user driving behaviors of the user; e.g., braking distance maintained with respect to a leading vehicle may seem overcautious to users who prefer shorter braking distances, and unsafe to users who prefer longer braking distances. Presented herein are techniques for controlling vehicles according to the user driving behaviors of users. While a user operates a vehicle in a driving context, a device monitors various driving features (e.g., acceleration or braking) to determine various user driving behaviors. When requested to control a driving feature of the vehicle, a controller may identify the user driving behaviors of the user in the driving context, and control the driving features according to the user driving behaviors, thus personalizing automated driving to the preferences of the user. 1.
