Abstract
A vehicle temperature control device for temperature control of a vehicle when the engine is stopped is provided, comprising: an engine-stop signaling device providing an engine-stop signal (MS) indicating an engine-stop; and an off-time temperature controller receiving a signal from the engine-stop signaling device and comprising at least an off-time temperature control automatic which can be switched on and off. The off-time temperature controller is adapted such that, when the off-time temperature control automatic has been switched on and when a heating demand is given, off-time temperature control is automatically started upon receipt of an engine-stop signal (MS).
Claims12
A construction vehicle having a temperature control device for heating a hydraulic liquid of the construction vehicle when an engine of the construction vehicle is stopped, comprising:
- the temperature control device having a vehicle engine-on and engine-stop signaling device;
- a temperature controller which is switchable on and off;
- and
- wherein the temperature controller is configured such that when the temperature controller has been switched on and upon receipt of a heating demand, the temperature controller automatically commands a construction vehicle heat source to heat the hydraulic liquid upon receipt of an engine-stop signal from the engine-on and engine-stop signaling device.
A method for controlling temperature of a hydraulic liquid of a construction vehicle, comprising the steps of:
- switching on a temperature controller;
- sensing and signaling an engine stop to the temperature controller;
- and
- demanding a construction vehicle heat source, by the temperature controller, to heat the hydraulic liquid, if necessary, when the temperature controller is switched on and upon receiving an engine stop signal.
