Embodiment Construction

[0025] figure 1 An embodiment of a drive system 10 of a hybrid vehicle is shown schematically with an internal combustion engine 11 and an electric machine 12 , which are connected via a belt drive 13 and connected to a common coolant circuit 14 . The air conditioner controller 15 and the cooling water pump 16 are also connected to the belt drive 13 . The motor 12 is connected to a battery 18 through an inverter 17 . An external energy input 20 is also possible via the charging device 19 . The electric machine 12 can be used to heat the coolant in the coolant circuit 14 and to heat the internal combustion engine 11 and the passenger compartment.

[0026] figure 2 An exemplary embodiment of a parking heating system 21 is shown. Here, the power loss P of the motor 22 is adjusted by the regulating unit 23 V Adjust to the desired target value P VSoll . The power loss generated in the motor 22 changes the coolant in the coolant circuit 29 from the inflow temperature T Zula...

Abstract

The invention relates to a parking heating system for a motor vehicle driven by an electric motor and a method for implementing a parking heating function in a motor vehicle with an electric drive train.

Description

technical field [0001] The invention relates to a heating system for a motor vehicle driven by an electric motor and to a method for implementing a heating function in a motor vehicle with an electric drive train. Background technique [0002] The function of the parking heating system is provided as special equipment for motor vehicles with an internal combustion engine. For this function, for example, fuel is burned in specially installed hardware and the heat generated is used to heat the internal combustion engine and the interior of the vehicle. However, the required additional hardware leads to higher costs, higher weight and installation space requirements. [0003] Various alternatives have been proposed to conventional parking heating systems that can be used in electric or hybrid vehicles. [0004] A method and a device for controlling waste heat management are known from DE 10 2014 112 201 A1. Here, the waste heat generated by the electronic components of the h...
