Dynamic Driving Task. 5.2.1. The activated system shall keep the vehicle inside its lane of travel and ensure that the vehicle does not cross any lane marking (outer edge of the front tyre to outer edge of the lane marking). The system shall aim to keep the vehicle in a stable lateral position inside the lane of travel to avoid confusing other road users.
5.2.2. The activated system shall detect a vehicle driving beside as defined in paragraph 7.1.2. and, if necessary, adjust the speed and/or the lateral position of the vehicle within its lane as appropriate.
5.2.3. The activated system shall control the speed of the vehicle.
5.2.3.1. The maximum speed up to which the system is permitted to operate is 60 km/h.
5.2.3.2. The activated system shall adapt the vehicle speed to infrastructural and environmental conditions (e.g. narrow curve radii, inclement weather).
5.2.3.3. The activated system shall detect the distance to the next vehicle in front as defined in paragraph 7.1.1. and shall adapt the vehicle speed in order to avoid collision. While the ALKS vehicle is not at standstill, the system shall adapt the speed to adjust the distance to a vehicle in front in the same lane to be equal or greater than the minimum following distance. In case the minimum time gap cannot be respected temporarily because of other road users (e.g. vehicle is cutting in, decelerating lead vehicle, etc.), the vehicle shall readjust the minimum following distance at the next available opportunity without any harsh braking unless an emergency manoeuvre would become necessary. The minimum following distance shall be calculated using the formula: dmin = vALKS* tfront Where: dmin = the minimum following distance vALKS = the present speed of the ALKS vehicle in m/s tfront = minimum time gap in seconds between the ALKS vehicle and a leading vehicle in front as per the table below: Present speed of the ALKS vehicle Minimum time gap Minimum following distance 7.2 2.0 1.0 2.0 10 2.78 1.1 3.1 20 5.56 1.2 6.7 30 8.33 1.3 10.8 40 11.11 1.4 15.6 50 13.89 1.5 20.8 60 16.67 1.6 26.7 For speed values not mentioned in the table, linear interpolation shall be applied. Notwithstanding the result of the formula above for present speeds below 2 m/s the minimum following distance shall never be less than 2 m.
5.2.4. The activated system shall be able to bring the vehicle to a complete stop behind a stationary vehicle, a stationary road user or a blocked lane of travel to avoid a collision. This shall be ensured up to the ma...
Dynamic Driving Task. The fulfilment of the provisions of this paragraph shall be demonstrated by the manufacturer to the technical service during the inspection of the safety approach as part of the assessment to Annex 4 (in particular for conditions not tested under Annex 5) and according to the relevant tests in Annex 5.

5.2.1. The activated system shall keep the vehicle inside its lane of travel and ensure that the vehicle does not unintentionally cross any lane marking (outer edge of the front tyre to outer edge of the lane marking). The system shall [drive smoothly], aiming to keep the vehicle in a stable lateral [and longitudinal] position motion inside the lane of travel to avoid confusing other road users [or requiring them to take unnecessary avoiding action.]
5.2.2. The activated system shall detect a vehicle driving beside as defined in paragraph 7.1.2. and, if necessary, adjust the speed and/or the lateral position of the vehicle within its lane as appropriate.
5.2.3. The activated system shall control the speed of the vehicle.
Dynamic Driving Task. 5.2.1. The activated system shall keep the vehicle inside its lane of travel and ensure that the vehicle does not unintentionally cross any lane marking (outer edge of the front tyre to outer edge of the lane marking). The system shall aim to keep the vehicle in a stable lateral and longitudinal motion inside the lane of travel to avoid confusing other road users. The system shall aim to recover the original safe state of motion after disturbances not requiring an emergency manoeuvre.
5.2.1.1. A vehicle with ALKS enabled, and equipped with a sensing system to the front, side and rear that is sufficient to assess the criticality of crossing into another lane, is permitted to intentionally cross lane markings when:
(a) performing an LCP according to paragraph 5.2.6.;
(b) performing an evasive lane crossing during an EM according to paragraph 5.3.;
(c) forming an access corridor for emergency and enforcement vehicles according to paragraph 5.2.1.2.;
(d) partly entering into the adjacent lane according to paragraph 5.
