Помощь в стабильности трейлера

(Опция/аксессуар.)

Trailer Stability Assist (TSA¹) is part of the ESC² stability system and is a function designed to help stabilize a vehicle that is towing a trailer when the vehicle and trailer have begun to sway. The function is added when installing a towbar. Contact a Volvo retailer for more information.

Причины раскачивания

Буксировка автомобиля прицепа может начать качаться по разным причинам. Normally this only occurs at high speeds. However, if the trailer is overloaded or unevenly distributed, e.g. Слишком далеко назад, существует риск покататься даже на низких скоростях.

Качание может быть вызвано такими факторами, как:

• Транспортное средство и трейлер пострадали от внезапного, сильного бокового ветра.
• Транспортное средство и трейлер путешествуют по неровной дороге или над ударом.
• Внезапные движения рулевого колеса.

Как только раскачивается, может быть трудно или невозможно остановить его. This makes the vehicle and trailer difficult to control and there is a risk of swerving into oncoming traffic or driving off the road.

Функция помощи в стабильности трейлера

Trailer Stability Assist continuously monitors the vehicle's movements, particularly lateral movements. If swaying is detected, the brakes are applied individually on the front wheels, which has a stabilizing effect on the vehicle and trailer. This is often enough to enable the driver to regain control of the vehicle.

If the Trailer Stability Assist function's first attempt is not adequate to stop the swaying motion, the brakes are applied on all wheels and engine power is temporarily reduced. As the swaying motion begins to decrease and the vehicle and trailer have once again become stable, TSA stops regulating the brakes/engine power and the driver regains control of the vehicle.

Trailer Stability Assist may not intervene if the driver tries to compensate for the swaying motion by moving the steering wheel rapidly, because the system will then not be able to determine if it is the trailer or the driver causing the swaying.

When Trailer Stability Assist is activated, the ESC symbol is displayed in the instrument panel.
