Method for controlling vehicle propulsion, comprises computer program which disconnects the engine braking effect when rallying and reconnects it under particular conditions of slope

摘要

A computer program detects rallying and disconnects the engine by use of the clutch. The engine braking effect is then used or not according to slope and a compromise between saving fuel and pollution and brake wear. The computer program includes stages such as, rallying commenced (105), is speed above zero (110), has brake pedal operated (115), has set time expired (120), speed tests (125) and cut engine options (130,135).
