Abstract
A method and a device for the control/regulation of the heat flows caused by heat generators and heat consumers in a motor vehicle, at least on the basis of a momentary load state of the motor vehicle engine and the momentary vehicle operating conditions and ambient conditions. A control/regulation device makes a forecast of the load state of the engine cooling system lying ahead, on the basis of a model that takes into consideration driving condition-relevant quantities and the thermal inertia of the engine cooling system and of engine load-relevant ambient conditions lying ahead, recorded by a satellite navigation system, and carries out a corresponding control/regulation of all heat flows in the motor vehicle, especially of the engine cooling system.
Claims13
A method for controlling heat flows produced by heat generators and heat consumers in a motor vehicle, comprising:
- making a forecast of upcoming load conditions of an engine cooling system of the motor vehicle, as a function of a model that considers quantities relevant to a driving condition and a thermal inertia of the engine cooling system, and of recorded load-relevant ambient conditions that lie ahead in a direction of travel;
- and
- controlling heat flows in the motor vehicle as a function of present vehicle operating states and ambient conditions, a present load condition of an engine of the motor vehicle, and the forecast of the upcoming load conditions of the engine cooling system.
A device for thermal management of heat flows in a motor vehicle, comprising:
- a control device making a forecast of upcoming load conditions of an engine cooling system of the motor vehicle, as a function of a model that considers quantities relevant to a driving condition and a thermal inertia of the engine cooling system, and of recorded load-relevant ambient conditions that lie ahead in a direction of travel, the control device controlling heat flows in the motor vehicle as a function of present vehicle operating states and ambient conditions, a present load condition of an engine of the motor vehicle, and the forecast of the upcoming load conditions of the engine cooling system.
An air conditioning system of a motor vehicle, comprising:
- a control device making a forecast of upcoming load conditions of an engine cooling system of the motor vehicle, as a function of a model that considers quantities relevant to a driving condition and a thermal inertia of the engine cooling system, and of recorded load-relevant ambient conditions that lie ahead in a direction of travel, the control device controlling heat flows in the motor vehicle as a function of present vehicle operating states and ambient conditions, a present load condition of an engine of the motor vehicle, and the forecast of the upcoming load conditions of the engine cooling system;
- sensors operationally coupled to the control device;
- and
- actuating mechanisms operationally coupled to the control device.
