Commission Implementing Regulation (EU) 2016/799Show full title

3.2 Speed, position and distance measurement U.K.

(21) The motion sensor (possibly embedded in the adaptor) is the main source for speed and distance measurement. U.K.

(22) This function shall continuously measure and be able to provide the odometer value corresponding to the total distance travelled by the vehicle using the pulses provided by the motion sensor. U.K.

(23) This function shall continuously measure and be able to provide the speed of the vehicle using the pulses provided by the motion sensor. U.K.

(24) The speed measurement function shall also provide the information whether the vehicle is moving or stopped. The vehicle shall be considered as moving as soon as the function detects more than 1 imp/sec for at least 5 seconds from the motion sensor, otherwise the vehicle shall be considered as stopped. U.K.

(25) Devices displaying speed (speedometer) and total distance travelled (odometer) installed in any vehicle fitted with a recording equipment complying with the provisions of this Regulation, shall comply with the requirements relating to maximum tolerances (see 3.2.1 and 3.2.2) laid down in this Annex. U.K.

(26) To detect manipulation of motion data, information from the motion sensor shall be corroborated by vehicle motion information derived from the GNSS receiver and optionally by other source(s) independent from the motion sensor. U.K.

(27) This function shall measure the position of the vehicle in order to allow for the automatic recording of: U.K.

• positions where the driver and/or the co-driver begins his daily work period;

• [F1 positions where the accumulated driving time reaches a multiple of three hours;]

• positions where the driver and/or the co-driver ends his daily work period.

Textual Amendments

F1 Substituted by Commission Implementing Regulation (EU) 2018/502 of 28 February 2018 amending Implementing Regulation (EU) 2016/799 laying down the requirements for the construction, testing, installation, operation and repair of tachographs and their components (Text with EEA relevance).

3.2.1 Measurement of distance travelled U.K.

(28) The distance travelled may be measured either: U.K.

• so as to cumulate both forward and reverse movements, or

• so as to include only forward movement.

(29) The recording equipment shall measure distance from 0 to 9 999 999,9 km. U.K.

(30) Distance measured shall be within the following tolerances (distances of at least 1 000 m.): U.K.

• ± 1 % before installation,

• ± 2 % on installation and periodic inspection,

• ± 4 % in use.

(31) Distance measured shall have a resolution better than or equal to 0,1 km. U.K.

3.2.2 Measurement of speed U.K.

(32) The recording equipment shall measure speed from 0 to 220 km/h. U.K.

(33) To ensure a maximum tolerance on speed displayed of ± 6 km/h in use, and taking into account: U.K.

• a ± 2 km/h tolerance for input variations (tyre variations, …),

• a ± 1 km/h tolerance in measurements made during installation or periodic inspections,

the recording equipment shall, for speeds between 20 and 180 km/h, and for characteristic coefficients of the vehicle between 4 000 and 25 000 imp/km, measure the speed with a tolerance of ± 1 km/h (at constant speed).

Note: The resolution of data storage brings an additional tolerance of ± 0,5 km/h to speed stored by the recording equipment. U.K.

(34) The speed shall be measured correctly within the normal tolerances within 2 seconds of the end of a speed change when the speed has changed at a rate up to 2 m/s². U.K.

(35) Speed measurement shall have a resolution better than or equal to 1 km/h. U.K.

3.2.3 Measurement of position U.K.

(36) The recording equipment shall measure the absolute position of the vehicle using the GNSS receiver. U.K.

(37) The absolute position is measured in geographical coordinates of latitude and longitude in degrees and minutes with a resolution of 1/10 of a minute. U.K.
