New Hyundai tech can adjust performance based on payload

Korean manufacturer Hyundai has unveiled a system that can adjust the performance of an electric light commercial vehicle depending on the gross vehicle weight.

The system uses acceleration sensors to optimise the vehicle’s settings based on current gross weight estimate. This means an electric vehicle’s torque output can be optimised to maximize estimated remaining range. It reduces potential wheel spin and reduced traction when a vehicle is carrying less payload, increasing efficiency.

This technology also allows for changes in torque output based on topography, altering the amount of torque needed to propel a vehicle uphill based on its gross weight and allowing small business owners to effectively reduce unnecessary vehicle-related costs.

Chae Mo Yang, Group Leader of Eco-Technology Performance Development Group, said: “We are preparing for a future where we will be able to offer commercial EVs that operate at its optimum specifications under any given road condition and regardless of how much payload it is carrying. These vehicles will be very economical to operate.”

With this system, the vehicle estimates the distance it can drive and adjusts its maximum torque output. The potential vehicle range estimate is based on the accurate measurement of the current weight and speed of the vehicle, enhancing efficiency for commercial use.

For example, when the vehicle is carrying a heavy load, the vehicle automatically informs the driver of the estimated drive range to secure sufficient battery life to reach the destination safely.

Hyundai is currently considering using the technology in future electric LCVs.
