Hassle Free Vehicle Launch System
Abstract: During heavy traffic & uphill conditions, a critical task in driving a Manual Transmission vehicle is manoeuvring Launch Condition. This can be simplified by introducing Hassle Free Vehicle Launch (HFVL) assist feature. Implementation of proposed electro-mechanical sub-system in the vehicles under HFVL feature will lead to reduced clutch pedal efforts and give Engine ECU controlled automated seamless Vehicle Launch during bumper to bumper stop go driving conditions. HFVL incorporate a servo motor on clutch pedal to optimize the clutch engagement rate during clutch modulation zone and algorithm for engine torque demand control based on the clutch slippage during vehicle launch. HFVL will facilitate the smooth launch of the vehicle avoiding an engine stall events during launch event on a gradient road. With the developed algorithm, HFVL will be active only during vehicle launch events and will not affect the clutch engagements during on the fly gear shifts. Figure-1
