acquiring current load information of the vehicle; and setting the accelerator response of the vehicle according to the current load information.

2 . The method according to claim 1 , wherein acquiring the current load information includes:
acquiring tire information of the vehicle, the tire information including at least one of a tire pressure or a tire deformation; and calculating the current load information according to the tire information.

3 . The method according to claim 2 , wherein setting the accelerator response includes:
acquiring no-load vehicle weight information and a no-load accelerator response of the vehicle; obtaining current total weight information of the vehicle according to the current load information and the no-load vehicle weight information; and setting the accelerator response according to the no-load accelerator response and the current total weight information.

4 . The method according to claim 2 , wherein:
the tire information includes the tire pressure, and calculating the current load information includes calculating the current load information of the vehicle according to a current tire pressure and a no-load tire pressure.

5 . The method according to claim 4 , wherein setting the accelerator response includes:
acquiring no-load vehicle weight information and a no-load accelerator response of the vehicle; obtaining current total weight information of the vehicle according to the current load information and the no-load vehicle weight information; and setting the accelerator response according to the no-load accelerator response and the current total weight information.

6 . The method according to claim 2 , wherein:
the tire information includes the tire deformation, and calculating the current load information includes calculating the current load information according to a current tire deformation and a no-load tire deformation.

7 . The method according to claim 6 , wherein setting the accelerator response includes:
acquiring no-load vehicle weight information and a no-load accelerator response of the vehicle; obtaining current total weight information of the vehicle according to the current load information and the no-load vehicle weight information; and setting the accelerator response according to the no-load accelerator response and the current total weight information.

8 . The method according to claim 1 , wherein setting the accelerator response includes:
acquiring no-load vehicle weight information and a no-load accelerator response of the vehicle; obtaining current total weight information of the vehicle according to the current load information and the no-load vehicle weight information; and setting the accelerator response according to the no-load accelerator response and the current total weight information.

9 . A device for setting an accelerator response of a vehicle, comprising:
a controller; and a memory for storing instructions that, when executed by the controller, cause the controller to:
acquire current load information of the vehicle; and
set the accelerator response of the vehicle according to the current load information.

10 . The device according to claim 9 , wherein the instructions further cause the controller to:
acquire tire information of the vehicle, the tire information including at least one of a tire pressure or a tire deformation; and calculate the current load information according to the tire information.

11 . The device according to claim 10 , wherein the instructions further cause the controller to:
acquire no-load vehicle weight information and a no-load accelerator response of the vehicle; obtain current total weight information of the vehicle according to the current load information and the no-load vehicle weight information; and set the accelerator response according to the no-load accelerator response and the current total weight information.
