Embodiment Construction

[0034] exist figure 1 shows an internal combustion engine 1 in which a piston 2 can move up and down in a cylinder 3 . The crankshaft 14 is set into a rotational movement by means of the pistons, through which at least one motor wheel is ultimately driven with a drive torque. For this purpose, the crankshaft is connected to a drive chain, which generally has a transmission, clutch, brake, electric motor, etc.

[0035] The cylinder 3 is equipped with a combustion chamber 4 on which an intake pipe 6 and an exhaust gas pipe 7 are connected via a valve 5 . The intake pipe 6 and the exhaust gas pipe 7 are connected through an exhaust gas return valve 13 having a valve flap 13a, which serves as an adjustment link for the return of exhaust gas to the outside. The valve flap 13 a can be controlled by a signal EGR from a controller (ECU) 16 . Furthermore, an injection valve 8 , which is controlled by the signal TI, and an ignition plug 9 , which is controlled by the signal ZW, are c...

Abstract

The invention relates to a method for preparing an acceleration process of a motor vehicle, wherein at least one wheel of the motor vehicle is driven by an internal combustion engine, wherein, as a result of a first event (102) that indicates the acceleration process, a first variable that influences drive torque on the at least one wheel is modified such that the drive torque is increased (103) on the at least one wheel, and a second variable that influences drive torque on the at least one wheel is modified such that the drive torque is reduced (103) on the at least one wheel, and wherein, as a result of a second event that triggers the acceleration process, the second variable that influences the drive torque on the at least one wheel is modified such that the drive torque is increased (106) on the at least one wheel.

Description

technical field [0001] The invention relates to a method for preparing an acceleration process of an internal combustion engine. Background technique [0002] Many systems are used in motor vehicles which make the driving behavior more comfortable and which reduce the fuel consumption of the motor vehicle. For example, automatic or semi-automatic transmissions, in particular double clutch transmissions, enable fast and automatic switching processes. Reduced fuel consumption can thus be achieved by automatically advancing the transmission into a higher gear. The maximum engine torque and the maximum engine power of the internal combustion engine can be achieved with a turbocharger and provide the driver with a comfortable and sporty driving feeling. [0003] However, if the driver wants to carry out the acceleration process spontaneously and wants to increase the engine torque quickly, a delayed response behavior of the system can occur. The system may initially be switche...
