Embodiment Construction

[0020] figure 1 As the central element of the longitudinal adjustment or speed adjustment system, a control unit SE is shown, which receives the different input signals SHOS, sKS, fv, sS and v and generates an output signal a.

[0021] Basically, the control unit SE is constructed in such a way that it is based on the signal sS of the sensor system S and a driver preset value fv predetermined by the driver by means of the input unit mEE (for example, the theoretical speed and / or the actual speed to be followed) The distance range of the preceding vehicle) sends an acceleration signal a to the corresponding actuation mechanism Ak, which includes a drive unit A and a brake unit B to achieve the desired acceleration. In this case, the sensor system S is configured in such a way that by means of the radar system and / or the camera system it is possible to detect the traffic in front and therefore in particular the preceding vehicle which is important for speed regulation. These import...

Abstract

The invention relates to a longitudinal control system for a motor vehicle, comprising a sensor system for detecting a traffic event lying ahead, in particular in order to locate vehicles traveling ahead, and comprising a control unit for automatically controlling the speed or the acceleration of the motor vehicle to a standstill on the basis of the traffic event lying ahead. An automatic drive-off is allowed without a driver confirmation within a specified time interval after reaching the standstill, and after the time interval has expired, an automatic start-up is allowed after a start-up confirmation is triggered by the driver. According to the invention, a start-up confirmation is triggered if a contacted state of the steering wheel is detected starting from a non-contacted state of the steering wheel.

Description

Technical field [0001] The invention relates to a longitudinal adjustment system for a motor vehicle according to the preamble of claim 1. Background technique [0002] Motor vehicles with a longitudinal control system or a speed control system have long been known. Most currently available speed control systems adjust the speed of the motor vehicle to a predetermined desired or theoretical speed. [0003] In addition to these longitudinal adjustment systems, some manufacturers have now also obtained longitudinal adjustment systems with extended distance adjustment, so-called distance-dependent longitudinal adjustment systems or speed adjustment systems. This longitudinal adjustment system or speed adjustment system, for example, the system provided by the applicant under the name "Active Cruise Control" can achieve the desired or the desired distance while maintaining the desired distance from the preceding vehicle. The vehicle is automatically guided at a correspondingly lower ...
