Operating device for controlling the operation of a motor vehicle comprising an electric motor, and motor vehicle

Abstract

A control device for controlling operation of a motor vehicle having an electric motor in at least three operating states. In a first operating state, the motor vehicle is off; in a second operating state, the motor vehicle is on and the electric motor is not controllable; and in a third operating state, the motor vehicle is on and the electric motor is in operation. The control unit includes a basic control element for turning the motor vehicle on and off, and a gear-shift control element for selecting a gear-shift stage. The motor vehicle can be switched from a first operating state to a second operating state by a signal from the basic control element when the motor vehicle is turned on, and from the second operating state to the third operating state with the gear-shift control element by selecting a gear-shift stage associated with the third operating state.

Description

technical field [0001] The invention relates to an operating device for controlling the operation of a motor vehicle comprising an electric motor in at least three operating states, wherein in a first operating state the motor vehicle is switched off and in a second operating state the motor vehicle is not steerable by the electric motor In the case of switching on, in the third operating state the motor vehicle is switched on and the electric machine is running. Furthermore, the invention relates to a motor vehicle having such an operating device. Background technique [0002] In motor vehicles with an internal combustion engine, it is already known to use three different positions of an operating device, for example an ignition key. In addition to simply switching on the motor vehicle—this means that systems that can be operated by the driver, such as the infotainment system, can be operated, for example by continuing to turn the ignition key, and the internal combustion ...

AI Technical Summary

Problems solved by technology

[0003] In motor vehicles with an electric motor, especially in hybrid vehicles in which only the electric motor is initially used at low speeds, there is no acoustic feedback of the internal combustion engine, so that the different operating states of the motor vehicle are no longer clearly distinguishable to the driver Minute

There are therefore multiple operating states from which the driver can poorly separate

[0004] Another major disadvantage of the known motor vehicle is that, in order to start the motor vehicle, not only the operating element for switching on the motor vehicle must be actuated, but also additional operating actions must be carried out, irrespective of the drive position inserted in the automatic transmission. , most often by depressing the brake in the form of a brake pedal

Furthermore, this known operating device is ultimately unreliable, since it is ultimately not clear to the driver whether the electric motor is running, since no acoustic feedback is present

This also results in additional risks, such as the risk of the motor vehicle leaving while the drive engine is running, wherein the motor vehicle can move automatically or even a battery discharge occurs due to the continuous activation of the motor vehicle
