Over 50% of incidents, while driving on hilly terrains, slopes or gradients occur due to unintentional rollback of vehicles. Driving on a slope is a litmus test even for well-experienced drivers. Oftentimes, CVs are equipped with inadequate safety technologies to aid drivers. The need for safety technologies become crucial to support drivers while driving on gradients or slopes. Hill Start Aid (HSA) is one-of-a-kind technology introduced for commercial vehicles that prevents vehicles from unintended rollbacks while driving on slopes and maximizes driver safety and comfort.
Did you know HSA is an add-on functionality to Antilock Braking System (ABS)? Yes, HSA can simply be activated on the ABS system and does not require any additional hardware / modifications on the vehicle. The safety feature supports the driver by giving them the time required to take the vehicle back into control on inclines, optimizes vehicle stability, and averts unintended collision due to rollbacks.
Hill Start Aid improves safety during ‘stop and go’ situations on hilly terrains or slopes. The feature is supplemented with Automatic Traction Control which offers greater vehicle stability and increased tyre life.
The technology automatically gets activated through the flick of a switch when drivers shift their foot off the accelerator pedal and presses the brake. It stabilizes and holds the vehicle on a slope, after disengaging the brakes thereby giving the time needed for drivers to launch the vehicle forward. It uses a pressure sensor that measures the driver’s braking demand and enables them to accelerate gently, without the intervention of the brakes or clutch.
As a technology leader in the commercial vehicle industry, ZF has been synonymous with innovating active safety technology for over five decades worldwide. ZF has been the choice of leading vehicle manufacturers by developing technology that assists in vehicle stability, reducing accident risk, repair cost and improving vehicle uptime. With a proven track record of making vehicles safer, Hill Start Aid offers a great deal of benefits ranging from aversion of unintended rollback to maximizing driver comfort and safety.
