Unsure about Electronic Stability Control in your RV or caravan?
Here’s the lowdown.
Electronic Stability Control (ESC) is one of the greatest improvements in caravan safety to have been introduced in recent times. The technology has been adapted for vans from one pioneered by the auto industry for use in motor vehicles. The complicated vehicular system, such as those found in motorhomes, senses and compares the vehicle’s trajectory with the driver’s steering input. When things are starting to look troubling, the system reduces engine power and applies selective braking to bring the vehicle back under control.
The ESC system in a caravan is a bit more straightforward, since it doesn’t need to account for steering and engine output, it merely has to keep the van in its rightful orientation.
It’s easy to appreciate the importance of ESC when you consider that shaking and sway leading to loss of control is a major contributor to accidents involving vans. No matter how careful a driver is to avoid sway, it’s almost impossible to eliminate the on-road factors that can set a van to shaking; these can include anything from road surface, buffeting slipstreams from oncoming trucks, uneven tyre pressures, poor packing and wind. When left unchecked, these can build up to the point where a van loses balance and topples over, sometimes taking a vehicle over with it.
