While Anti-lock Braking System (ABS) is already mandated as a regulatory compliance as per Central Motor Vehicle Rules for all CVs above 12 ton GVW, ESC in heavy vehicles is a fresh start. It extends the safety further by providing vehicle stability under arduous road conditions during handling maneuvers. The technology can predict instability scenarios and automatically intervene by braking, thus averting rollover, skidding and jack-knifing. It reckons the lateral acceleration and vertical axis constancy of the vehicle through sensors, only to apply brakes on selective wheels to tackle instability. Tata´s `ESCsmart´ ESC technology kick-starts a whole new beginning in vehicular safety in the Indian CV segment, and will prompt other OEs to bring in similar technologies into the market.

ESC can will preventing jack-knifing in tractor-trailer, improve directional stability during dynamic maneuvers, prevent roll over during turning at high speed.

The Automatic Traction Control, on the other hand, prevents wheel spin during acceleration under slippery surface conditions. This will address loss of traction of one or more wheels, while also enduring the life of tyres by curbing unnecessary spins. The Hill Start Aid can avoid roll back of vehicles on an uphill gradient after a stop, thereby drivers can move the vehicle with ease. It will also reduces clutch and brake liner wear.
