A Study on the Improvement of EV One-Pedal Driving System Interface and Cost Reduction
In this study, big data analysis and user survey of driving records were conducted to investigate frequency of use and ease of operation of the regen paddle to control one-pedal driving system in electric vehicle. According to3.8 million driving record big data analysis result, it was found that the driver manipulates 3.31 times on average during a single trip, mainly during the early stages of driving. According to user observation research result, 41.8% of participates did not used or used less than 5 time of regen paddle during one single trip. Also 336 participants, which is 83%, responded that the regen paddle manipulated for one-pedal driving was inconvenient. In conclusion, because the use frequency of the regen paddle is low and the operation convenience is bad, it seems necessary to change the design of the regen paddle.
