Launch control acceleration method

Abstract

The present invention relates to a launch control acceleration method, which is used in a vehicle. The vehicle includes an engine, a driving power generation system, a battery and an engine control unit. The engine is provided with a crankshaft. The driving power generation system includes a driving power generation controller, a driving power generator and a position sensor. The driving power generation controller can receive a key switch signal, an engine start signal, a throttle opening signal, a vehicle speed signal and a launch control signal. The driving power generator is coaxially arranged with the crankshaft. The battery is electrically connected to drive the power generation controller. The engine control unit communicates with the engine, driving power generator controller and battery to control the engine's fuel injection and ignition. Wherein, through the launch control acceleration method of the present invention, before the vehicle is ready to start accelerating, it drives the generator to output power in advance to increase the engine speed to a speed close to the clutch engagement point of the continuously variable transmission mechanism. When the driver turns the throttle, the engine speed rises rapidly, and the continuously variable transmission mechanism engages the engine in a very short time, so that the driver has the shortest starting response time and a faster initial speed.
