摘要

A method for selection of motion during traction of a vehicle at a condition of traction on the rise severe.The present invention relates to a method for selection of motion during traction of a vehicle at a condition of traction in severe rise, said vehicle comprising an engine (1),An automated mechanical transmission (9), a clutch (3), a control unit (45) for receiving input signals including signals indicative of the speed of the vehicle.The transmission ratio is engaged, rotational speed of the engine.Rotational speed of an input shaft and displacement of a control throttle (48 for requirement of engine torque.And for processing these signals in accordance with rules logic programmed to issue signals out of command to the engine (1),For such transmission (9) and the clutch (3).In accordance with the present invention, when sensing a condition of traction in severe rise, a motion target is determined for that condition of traction in severe rise,The motion target with the highest possible with respect to the lowest possible where the vehicle in view of at least current circumstances.There will be at least theoretically capable of holding a vehicle speed or constant acceleration at least somewhat.And where additional screening of reduction of March will be adjusted so that no idle running lower than said target will be selected and engaged.
