Los sistemas ADAS (sistemas avanzados de ayuda a la conducción) instalados en el vehículo, ¿pueden ser desconectados en algún momento?
Can the ADAS systems (advanced driver assistance systems) fitted in the vehicle be switched off at any time?
- APueden desconectarse de forma permanente pero nunca de forma temporal.They can be switched off permanently, but never temporarily.
- BSí, de forma permanente o temporal.Yes, permanently or temporarily.
- CNo pueden desconectarse en ningún caso.They can never be switched off.
ExplanationUsing sensors and smart cameras, ADAS (Advanced Driver Assistance Systems) greatly improve the vehicle's active safety. They give the driver useful information that helps with decisions and creates a safe environment in the vehicle. Where applicable, they can also intervene safely in driving when the driver does not respond to a dangerous situation. However, the driver must remember that these systems are only a driving aid, and some of them may not work properly in certain conditions such as rain, fog, ice, snow, dust clouds or smoke. Dirt can make a sensor or camera ineffective, and in that case it would be advisable to switch it off if necessary. These systems can usually be switched off permanently, or temporarily at a given moment by the driver, who must have complete control of the vehicle. So using them does not free the driver from responsibility for causing an accident or dangerous situation by using these systems wrongly, by trusting them too much or by ignoring a signal or order from a traffic officer.
En cuanto a los sistemas de ayuda a la conducción, ¿cómo funciona el sistema avanzado AEB-PCD o de frenado de emergencia frente a peatones y ciclistas?
Regarding driver assistance systems, how does the advanced AEB-PCD system, or emergency braking for pedestrians and cyclists, work?
