Abstract
A heater system for preheating a vehicle and method of operating the same, wherein the method of operation is dependent upon the temperature of the coolant fluid In the vehicle coolant system.
Claims28
A method of operating a heater for preheating components of a vehicle via a fluid in a heat exchanger, the fluid having a parameter value indicative of flow capability, the method being operable prior to starting an engine of the vehicle, the method comprising:
- a) receiving a wake signal to commence heating;
- b) initiating a heating profile sequence of the heater to commence heating of the fluid, the heating profile sequence being selected from at least two heating profile sequences, the at least two heating profile sequences comprising a first heating profile sequence for use when the flow capability of the fluid is above a predetermined threshold value and a second heating profile sequence for use when the flow capability of the fluid is below a predetermined threshold value.
A control system for a heater for preheating vehicle components via fluid in a heat exchanger, the control system being for controlling a heating profile sequence of the heater, the heating profile sequence being selected from at least two heating profile sequences, the at least two heating profile sequences comprising a first heating profile sequence for use when the flow capability of the fluid is above a predetermined threshold value and a second heating profile sequence for use when the flow capability of the fluid is below a predetermined threshold value, the control system comprising a memory with at least two algorithms for controlling the heater, wherein:
- a first one of the at least two algorithms being executable when the controller receives a signal to initiate the heating profile sequence according to the first heating profile sequence;
- and
- a second one of the at least two algorithms being executable when the controller receives a signal to initiate the heating profile sequence according to the second heating profile sequence.

A method of operating a heater for preheating vehicle components via fluid in a heat exchanger, the method comprising:
- receiving a wake signal to commence heating;
- determining the value of a parameter indicative of the flow capability of a fluid to be heated;
- determining a start-up sequence of the heater based upon the determined parameter value;
- and
- initiating the selected start-up sequence to commence heating of the fluid.
