Method of determining a preconditioning status of a vehicle component or system
A method of determining a preconditioning status of a vehicle component or system. The method includes receiving a preconditioning status request for a vehicle component or system; determining the preconditioning status by a preconditioning model estimating the preconditioning status without activating the corresponding vehicle component or system.
1. A method of determining a preconditioning status of a vehicle component or system, the method comprises:
receiving a preconditioning status request for the vehicle component or system;
determining the preconditioning status by a preconditioning model estimating the preconditioning status, wherein the preconditioning model estimates the preconditioning status without activating the vehicle component or system that is subject to the preconditioning status request, wherein the determining of the preconditioning status is not periodically cycled, and
heating and/or cooling the vehicle component or system in response of determining that the preconditioning status is outside of a predetermined range.
2. The method according to claim 1 , wherein the preconditioning status is a temperature status, and the preconditioning status request comprises a request for the temperature of the vehicle component or system.
3. The method according to claim 1 , comprising providing the preconditioning model, wherein the preconditioning model utilizes known temperature characteristics of the vehicle component or system to estimate a current temperature of the vehicle component or system.
4. The method according to claim 1 , wherein the preconditioning model utilizes an ambient temperature of the vehicle to estimate a current temperature of the vehicle component or system.
5. The method according to claim 4 , further comprising measuring the ambient temperature of the vehicle, and providing the ambient temperature as input data to the preconditioning model.
6. The method according to claim 1 , comprising comparing the estimated preconditioning status with a reference value, and in response of determining that the estimated preconditioning status differs from the reference value by a set threshold, retrieving the actual preconditioning status of the vehicle component or system by activating the vehicle component or system, respectively.
7. The method according to claim 1 , wherein the vehicle component or system is an energy storage system or fuel cell system of the vehicle.
8. A non-transitory computer program comprising program code for performing the method according to claim 1 , when the program code is run on a computer.
9. A control unit for determining a preconditioning status of a vehicle component or system, the control unit being configured to:
receive a preconditioning status request for the vehicle component or system;
determine the preconditioning status by using a preconditioning model to estimate the preconditioning status, wherein the preconditioning model estimates the preconditioning status without activating the vehicle component or system that is subject to the preconditioning status request, wherein the determine of the preconditioning status is not periodically cycled, and
activate heating and/or cooling of the vehicle component or system in response of determining that the preconditioning status is outside of a predetermined range.
10. The control unit according to claim 9 , wherein the control unit is configured to measure an ambient temperature of the vehicle, and to provide the ambient temperature as input data to the preconditioning model.
11. The control unit according to claim 9 , configured to compare the estimated preconditioning status with a reference value, and in response of determining that the estimated preconditioning status differs from the reference value by a set threshold, retrieve the actual preconditioning status of the vehicle component or system by activating the vehicle component or system, respectively.
12. The control unit according to claim 9 , wherein the control unit is a control unit for an energy storage system or a fuel cell system of the vehicle.
13. A vehicle comprising the control unit of claim 9 .
