Tata Motors has introduced Electronic Stability Control (ESC) for its medium and heavy commercial vehicles. The CV maker is claimed to be the first to introduce the technology in India. Developed in partnership with Wabco India, the technology, according to Girish Wagh, Head – Commercial Vehicles, Tata Motors, will help to strengthen the safety performance of its products. Apart from ESC, Tata Motors has also introduced Automatic Traction Control (ATC) and Hill Start Aid (HSA) safety technology for its range of trucks and buses. According to Dr. AK Jindal, Head – Engineering, Commercial Vehicles, Tata Motors, ESC adds to the Anti-lock Braking (ABS) system, which was introduced as a part of regulatory compliance by the government for vehicles with 12-tonne GVW and above. Taking safety to the next level under demanding conditions, ESC predicts forthcoming instability and automatically intervenes by applying brakes to avoid rollover, skidding and jack-knifing. It measures vehicle’s lateral acceleration, roll about its vertical axis through sensors, and applies brakes on selective wheels to control instability. Benefits to fleet operator would include jack-knifing prevention in tractor-trailer, improve directional stability during dynamic manoeuvres, prevent roll over during turning at high speed. Where automatic Traction Control prevents wheel spin during acceleration on tricky, slippery surface, Hill Start Aid (HSA) prevents roll back of vehicle during ‘Stop & Go’ when going up-hill.
