Tata Prima’s Advanced Driver Assistance System (ADAS) Technology Explained
The Advanced Driver Assistance Systems (ADAS) offered in Tata Prima are developed in collaboration with WABCO India, with extensive testing and validation over the past five years.

Tata Motors has set a new benchmark in the Indian commercial vehicle space with the commercial introduction of ADAS option in its flagship heavy trucks range – the Prima. The list of active and passive safety features on offer includes Collision Mitigation System (CMS), Lane Departure Warning System (LDWS), Driver Monitoring System (DMS), Electronic Stability Control (ESC), and Tyre Pressure Monitoring System (TPMS).
The truck maker was indeed the first to demo and offer Electronic Stability Control (ESC) in heavy trucks in the country back in 2017. With the additional safety features, drivers and operators of the trucks can benefit from enhanced safety capabilities and integration (say, with fleet telematics) to take on various risk factors involved in the vehicle operations.
The ADAS features rely on a host of sensors (including radar and camera systems) and ECUs to compute and control a variety of road hazards including driver errors. The systems ensure that mitigatory indications are given to the driver at the event of a risk scenarios, and may even take over the braking controls at the last moment to prevent accidents.

At the launch event, Tata Motors showcased its flagship, ADAS-equipped Prima 5530.S tractor and Prima 3530.K heavy tipper in ‘Premium Tough’ avatar, with refreshed cabin styling and fresh interiors. It is expected that the manufacturer will extend the ADAS options to the top-end Signa variants as well in the coming months.
Collision Mitigation System (CMS)
Known as OnGuardASSIST in WABCO’s parlance, the CMS alerts the driver via audible signals in case of potential hazard, may it be a show moving vehicle or a stationary object. If the driver fails to respond with corrective measures immediately, the systems engages active braking to prevent the vehicle from hitting the objects on its way.

The CMS uses a powerful 77GHz radar sensor that guarantees system’s fool-proof performance in all weather and visibility scenarios. The radar’s high bandwidth ensures accuracy in detection of objects of all kind.
Lane Departure Warning System (LDWS)
WABCO’s OnLaneALERT, adapted by Tata Motors, identifies unintentional lane departures of the vehicle, using a forward-looking, windshield-mounted camera. It calculates and monitors the truck’s position relative to the lane in which it is moving, and makes warning noise if the vehicle transgresses to the next lane without the driver’s activation of turn signals.

This feature is a big boon for truck drivers, especially for multi-axle and tractor-trailers, as unintentional lane drift is a common phenomenon that puts both the vehicle and other road users at high risks. Alarm signals also make the drivers mindful of their lane sense and orientation in multi-lane highways at higher speeds.
