Problems solved by technology

It is difficult for the driver to drive his vehicle solely by the electric motor, since the driver does not know when the nominal torque, usually preset via the accelerator pedal, is greater than the torque provided by the electric motor

Embodiment Construction

[0028] exist figure 1 shows the accelerator pedal angle 1 , the setpoint drive torque 2 and the actual drive torque 3 or propulsion torque over time t of a hybrid vehicle comprising an electric motor and an internal combustion engine for driving. At the point in time t=0 the electric motor is started, but the internal combustion engine is not activated, so that the vehicle initially travels purely electrically.

[0029] To accelerate the vehicle, the driver continues to depress the accelerator pedal of the vehicle, which is indicated by the curve of the accelerator pedal angle 1 rising continuously. The curve of the setpoint drive torque 2 as a function of the accelerator pedal angle 1 essentially corresponds to the curve of the accelerator pedal angle 1 .

[0030] At the point in time t=x, the setpoint drive torque 2 corresponds to the torque 4 that can be provided by the electric motor. In hybrid vehicles according to the prior art, the internal combustion engine is starte...

Abstract

The vehicle (10) comprises, in addition to the internal combustion engine (7), an electric motor (8) for respectively driving the vehicle (10), when the rated drive torque (2) is greater than the drive torque (4) currently available by the electric motor (8) ) and the additional torque (5), the internal combustion engine (7) is automatically activated. In this case, the additional torque (5) is greater than zero.

Description

technical field [0001] The invention relates to a method for activating an internal combustion engine of a vehicle, in particular a hybrid vehicle, for driving the vehicle, as well as a correspondingly designed control device and a correspondingly designed vehicle. Background technique [0002] WO 02 / 26520 A1 discloses a torque manager which operates an electric motor and an internal combustion engine as a function of the desired wheel torque. [0003] DE19637210A1 describes a drive train control device which controls a drive source and a reduction unit depending on the positions of the accelerator pedal and the brake pedal. [0004] DE69831468T2 describes a drive control system by which shocks that may occur when starting an internal combustion engine during operation of a vehicle by an electric motor are prevented. [0005] According to the prior art, in a hybrid vehicle which includes both an electric motor and an internal combustion engine for driving, the internal comb...
