175 The navigator tells the system of the unit of measurement in force in the country in which you are travelling and converts the value consistently with the unit of measurement selected by the user. In this way, the speed limitation suggested by the ISA system or the speed offered by the IACC system will always be correct, regardless of the unit of measurement chosen by the user. The system can display the shape of the signs consistently with the current shape of the country in which you are travelling. Using the information contained in the navigator, the system can recognise motorway, urban and non-urban scenarios and to use the limits provided by the navigator to provide the most plausibly accurate speed limit. In addition, the system can recognise turns and provide, where necessary, the limit detected by the navigator in place of that recognised by the camera. INTELLIGENT SPEED ASSIST The "Intelligent Speed Assist" system can be used to set a speed limit on the "Speed Limiter" system equal to the one detected on the road signs by means of the "Traffic Sign Recognition" system, signalled to the driver on the instrument panel display. The minimum speed that can be set is 30 km/h (20 mph). The "Intelligent Speed Assist" system can be activated if the following systems are active: Speed Limiter (see the chapter in this section) Traffic Sign Recognition (see the chapter in this section) When the "Intelligent Speed Assist" system recognises a new road sign, it will suggest the new speed limit to the driver with a specific message and dedicated alerts depending on whether the road sign is higher (fig. 175) or lower (fig. 176) than the current speed stored by the Speed Limiter. Consider both unconditional speed limits and those valid in rain, snow or fog to be valid for speed limitation. 90 70 km/h km D POWER 123456 C 23° km RANGE 216 75 % 90 175 F0S1187 70 90 km/h km D POWER 123456 C 23° km RANGE 216 75 % 70 176 F0S1188 You can confirm by pressing the RES button the speed limit setting equal to the suggested sign. Once the speed limit provided by the "Traffic Sign Recognition" system has been acquired as the new Speed Limiter value, the activation of Intelligent Speed on the display and the relevant road sign is shown surrounded by green. |
