Abstract

A system for operating a vehicle includes at least one processor and at least one memory. The at least one memory includes computer program code. The at least one memory and the computer program code are configured, with the at least one processor, to cause the system to at least: receive information regarding temperatures from different temperature sensors at different locations, and impose, based on a difference between the temperatures, a restriction affecting an effect of a user input applying on the vehicle. The user input is configured to affect at least one of a position, orientation, velocity, or acceleration of the vehicle by a predetermined amount.

First claim

What is claimed is:

1 . A system for operating a vehicle, comprising:
at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the system to at least:
receive information regarding temperatures from different temperature sensors at different locations;
impose, based on a difference between the temperatures, a restriction affecting an effect of a user input applying on the vehicle, the user input being configured to affect at least one of a position, orientation, velocity, or acceleration of the vehicle by a predetermined amount.

2 . The system of claim 1 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the system to at least:
determine a reference temperature, the reference temperature being an estimated internal temperature of a battery operably coupled to the vehicle.

3 . The system of claim 2 , wherein:
the temperatures include a first temperature and a second temperature; and the at least one memory and the computer program code are further configured, with the at least one processor, to cause the system to at least:
determine the reference temperature by comparing the first temperature with the second temperature.

4 . The system of claim 3 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the system to at least:
in response to the first temperature being less than the second temperature:
determine the reference temperature to be less than the first temperature by a predetermined value; or
determine the reference temperature by multiplying the first temperature by a predetermined number, the reference temperature being less than the first temperature.

5 . The system of claim 3 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the system to at least:
determine the reference temperature to be equal to the first temperature in response to the first temperature being greater than or equal to the second temperature.

6 . The system of claim 1 , wherein:
the temperatures include a first temperature and a second temperature; and the at least one memory and the computer program code are further configured, with the at least one processor, to cause the system to at least:
in response to the first temperature being less than the second temperature, impose the restriction to restrict an operator of the vehicle to have less control over operation of the vehicle as compared to when the first temperature is equal to or greater than the second temperature.

7 . The system of claim 1 , wherein:
the temperatures include a first temperature and a second temperature; and the at least one memory and the computer program code are further configured, with the at least one processor, to cause the system to at least:
in response to the first temperature being less than the second temperature, impose the restriction to control the vehicle to enter a warm up mode.

8 . The system of claim 1 , wherein the temperatures include:
a temperature of a battery operably coupled to the vehicle; and a temperature of an environment surrounding the vehicle.

9 . The system of claim 1 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the system to at least:
compare one of the temperatures with a temperature threshold; and in response to the one of the temperatures being below the temperature threshold, impose the restriction to prevent the vehicle from taking off.

10 . The system of claim 1 , wherein the at least one memory and the computer program code are further configured, with the at least one processor, to cause the system to at least:
impose the restriction by attenuating the effect of the user input applying on the vehicle.

11 . The system of claim 10 , wherein a same user input given by a user has an attenuated effect on the vehicle under the restriction as compared to the vehicle under no restriction.

12 . The system of claim 10 , wherein:
the user input affects a change in at least one of the position, orientation, velocity, or acceleration of the vehicle; and under the restriction, the change occurs more gradually as compared to under no restriction.

13 . A method for operating a vehicle, comprising:
receiving information regarding temperatures from different temperature sensors at different locations; imposing, based on a difference between the temperatures, a restriction affecting an effect of a user input applying on the vehicle, the user input being configured to affect at least one of a position, orientation, velocity, or acceleration of the vehicle by a predetermined amount.

14 . The method of claim 13 , wherein:
the temperatures include a first temperature and a second temperature; and imposing the restriction includes in response to the first temperature being less than the second temperature, restricting an operator of the vehicle to have less control over operation of the vehicle as compared to when the first temperature is equal to or greater than the second temperature.

15 . The method of claim 13 , wherein:
the temperatures include a first temperature and a second temperature; and imposing the restriction includes in response to the first temperature being less than the second temperature, controlling the vehicle to enter a warm up mode.

16 . The method of claim 13 , wherein the temperatures include:
a temperature of a battery operably coupled to the vehicle; and a temperature of an environment surrounding the vehicle.

17 . The method of claim 13 , further comprising:
comparing one of the temperatures with a temperature threshold; and in response to the one of the temperatures being below the temperature threshold, imposing the restriction to prevent the vehicle from taking off.

18 . The method of claim 13 , wherein imposing the restriction by the effect of the user input applying on the vehicle includes attenuating the effect of the user input applying on the vehicle.

19 . The method of claim 18 , wherein a same user input given by a user has an attenuated effect on the vehicle under the restriction as compared to the vehicle under no restriction.

20 . The method of claim 18 , wherein:
the user input affects a change in at least one of the position, orientation, velocity, or acceleration of the vehicle; and under the restriction, the change occurs more gradually as compared to under no restriction.
