Embodiment Construction

[0025] A control system 1 of an electric heating unit of a motor vehicle comprises a power limiting device 2 and a temperature regulating device 3 . These two means cooperate to determine the control signals intended for the electric heating unit. "Electric heating unit" means any device capable of heating a heat transfer fluid, such as air or a stream of liquid, in order to generate air for heating the passenger compartment of a motor vehicle. Among these heating units, mention is made in particular of positive temperature coefficient devices comprising ceramics that become hot when electric current is applied. The control signal takes into account a temperature measurement of the heat transfer fluid of the electric heating unit, a temperature set point of the heat transfer fluid of the electric heating unit, a power measurement of the electric heating unit, and an authorized power level of the electric heating unit. figure 1 , 2 and 5 illustrate various embodiments of the ...

Abstract

System for operating an electric heating element provided on a motor vehicle equipped with an electric motor power unit comprising at least one electric motor, the electric heating element comprising a heat transfer fluid circuit, the operating system comprising means for limiting Means (2) for the power consumed by the electric heating element and means (3) for regulating the temperature, which cooperate so as to depend on the temperature measurement of the heat transfer fluid of the electric heating element, the temperature data of the heat transfer fluid of the electric heating element, the electric heating The power measurement of the element and the authorized power of the electric heating member issue a control signal.

Description

technical field [0001] The field of the invention relates to air conditioning control systems, and more particularly to the limitation of the power consumed by an air conditioning control system of a motor vehicle comprising a compressor and a heating unit. Background technique [0002] In electric or hybrid vehicles, the passenger compartment is generally heated by an element powered by a high-voltage battery. In some cases (when energy is needed for traction, or when the battery is low), it is necessary to limit the power consumed for thermal comfort. In addition, the power of heating units varies according to the market area and climate. It is therefore necessary to add a configuration dependent on the type of climate in order to adapt the limitation of the power of the heating unit to the various existing variants. This configuration is difficult to manage. [0003] Document US 6040561 discloses a high voltage network system and auxiliary heating control. This docume...
