Publication number: 20230146809Abstract: There is provided a method and control system for limiting a driver acceleration request of a vehicle. The vehicle comprises a controller arrangement that receives a driver acceleration request and determines whether the driver acceleration request is below an acceleration threshold. If so, it initiates a limiting protocol and dependent on the distance between a preceding vehicle and the host vehicle limits the acceleration of the vehicle in comparison to the driver acceleration request. The invention further relates to a vehicle comprising such as control system.Type: ApplicationFiled: November 9, 2022Publication date: May 11, 2023Inventor: Tommy Johansson
