Hyundai develops world’s first performance control for commercial EVs with weight estimation

&NewLine;<p>Hyundai Motor Group has developed and revealed a system that estimates the gross vehicle weight of a light duty commercial electric vehicle and optimizes performance accordingly&period; The development of the system is a first-ever for the industry&comma; utilizing acceleration sensors to optimize the vehicle’s settings based on current gross weight estimate&period; This technology is being considered by Hyundai Motor Group for use on future light duty electric commercial vehicles&period;<br><br> A statement signed by JH So&comma; head&comma; Global PR Team and made available to OpenLife&comma; Hyundai stated that the ability to calculate the gross weight of a vehicle on the move means that an electric vehicle’s torque output can be optimized to maximize estimated remaining range&period; This reduces potential wheel spin and reduced traction when a vehicle is carrying less payload&comma; increasing commercial efficiency&period; The new technology also allows for changes in torque output based on topography&comma; 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&period;<br><br> &OpenCurlyDoubleQuote;Hyundai developed this technology because we realize that we need to take a different approach when it comes to developing electric vehicles for commercial use&comma;” said Chae Mo Yang&comma; Group Leader of Eco-Technology Performance Development Group&period; &OpenCurlyDoubleQuote;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&period; These vehicles will be very economical to operate&period;”<br><br> Price competitiveness is key to the success of future electric light duty commercial vehicles for small business owners&period; Keeping this in mind&comma; Hyundai Motor Group developed the gross weight estimation technology by utilizing acceleration sensors instead of weight sensors&semi; developing the technology in this manner means that it can be applied to a vehicle not equipped with a costly air suspension system&period;<br><br> Using acceleration sensors&comma; gross weight is estimated through Newton’s law of acceleration&period; In short&comma; the less mass and more energy put on matter&comma; the faster speed it moves&period; So&comma; when pushing an object at a constant speed&comma; the weight of the object can be calculated depending on its acceleration rate&period;<br><br> Through this process&comma; the vehicle estimates the distance it can drive and adjusts its maximum torque output&period; Specifically&comma; the potential vehicle range estimate is based on the accurate measurement of the current weight and speed of the vehicle&comma; enhancing efficiency for commercial use&period;<br><br> For example&comma; when the vehicle is carrying a heavy load&comma; the vehicle automatically informs the driver of the estimated drive range to secure sufficient battery life to reach the destination safely&period;<br><br> Hyundai Motor Group has been making a great effort to develop environment-friendly commercial vehicles to contribute to global greenhouse gas reduction&period; Last year&comma; Hyundai Motor Group signed an MOU with the Swiss company H2 Energy to establish a joint venture&comma; Hyundai Hydrogen Mobility&comma; through which it will provide one thousand heavy duty fuel cell electric trucks for five years&period; <&sol;p>&NewLine;
