ESP traction control – What is it and how does it work?

ESP traction control

ESP traction control was the most hyped phrase in 2007, including words like ‘corporate accountability and ‘safety’ – You either have in on your fleet, or you don’t.

The Electronic Stability Program (ESP) is basically the most essential safety feature to get introduced for vans since the announcement of seatbelts. A device that is closely associated with the factors of safety and corporate accountability.

The recently launched Ford Transit has an ESP as a stock fitment. The Volkswagen Crafter and the Mercedes-Benz Sprinter also have it too.

The rest of the 2.6-3.5 tonne GVW vans in the UK sell ESP as an addon option or don’t have it at all.

Therefore, a further hierarchy can be seen fragmenting between safe and not so safe vehicles.

ESP Traction Control – How does it work?

There is a higher risk of drift and rollover in a van due to the ever-shifting centre of gravity due to payload placement.

Bosch has created a specific system for light-duty vehicles to adapt the control system in every situation automatically.

Bosch couples the algorithm to detect the load under the namesake Load Adaptive Control (LAC).

The algorithm specifies the equatorial position of the vehicle’s centre of gravity to elevate the way the vehicle behaves according to the weight shift when the braking is accelerated.

Additionally, the Load Adaptive Control (LAC) specifies the fleet’s characteristic speed depending heavily on the vehicle’s weight to determine the vehicle’s initial reaction to steering operation.

In the case of vans, the control provided by the Electronic Stability Program (ESP) conjoined with the LAC has significantly decreased the risk of rolling over while keeping the vehicle under control in even the most critical situation.

The safety factor in vans could be improved invariantly by the functions added further by ESP; i.e., the rollover risk drops even lower if the acute lateral acceleration forces are predicted even before they arise and the stabilising intervention they initiate.

The vehicle is under the influence of ESP to dynamically decide the braking of individual wheels. Therefore, increasing the safety while reducing the engine torque. Creating a distributed force across the axles following the present load leads to low maintenance costs.
