Embodiment Construction

[0027] The method according to the invention can preferably be implemented by carrying out the low-speed variant described below and the so-called "micro-slip" variant or by means of the corresponding two operating phases described below.

[0028]With regard to the first operating phase "low speed method", it should first be stated that in the pure internal combustion engine operation of the internal combustion engine involved here, for example a four-cylinder gasoline engine, the idling speed is generally not lower than 750 min -1 (=U / min). However, when carrying out the electric start according to the invention and the electric operation of the internal combustion engine associated with the electric start in the mentioned traction operation, the nominal idling speed can be reduced, because there is no need for Sustaining torque or minimum idle speed for smooth operation. Considering the torque of the electric machine, the idling speed of the internal combustion engine can i...

Abstract

The invention rlates to a method for start-up of a motor vehicle with a coupled hybrid drive comprising an internal combustion engine (100) and a motor (110). The internal combustion engine (100) and the motor (110) are directly coupled (105). A clutch (120), electronically controlled, is configured between the internal combustion engine (100) and a speed changer (115). It is particularly stipulated that rotating speed of the internal combustion engine (100) is decreased (505) to the lowerest in the first start-up phase from the idle state, the internal combustion engine (100) is operated by the motor (100) in the traction state and operates in the sliding state at the constant speed of the electronically-controlled cluth (120).

Description

technical field [0001] The invention relates to a motor according to the preamble of claim 1 for controlling a hybrid drive having an internal combustion engine and an electric machine coupled to the internal combustion engine and having an electronically controlled gear clutch. A method for starting a motor vehicle. Furthermore, the invention relates to a computer program, a machine-readable data carrier for storing the computer program, and an electronic controller, by means of the computer program, the machine-readable data carrier and the electronic A controller is able to implement the method according to the invention. Background technique [0002] Motor vehicles with a manual transmission and an automated clutch are known, which can be stopped simply by actuating the brake pedal and / or the gas pedal or the accelerator pedal without actuating the clutch pedal. and boot. In this case, in a stop-start motor vehicle, the internal combustion engine is temporarily switch...
