Abstract
Provided are a power steering method and a power steering device applied in a vehicle including a power steering assembly. The method includes detecting whether a direction changing wheel of the vehicle is a driving wheel; determining a power assisted gear position of the power steering assembly according to whether the direction changing wheel of the vehicle is the driving wheel; and controlling the power steering assembly to generate a power steering torque according to the power assisted gear position of the power steering assembly. The direction changing wheel of the vehicle is a front wheel or a rear wheel of the vehicle.

A power steering method, applied to a vehicle comprising a power steering assembly, the power steering method comprising:
- detecting whether a direction changing wheel of the vehicle is a driving wheel, wherein the direction changing wheel of the vehicle is a front wheel or a rear wheel of the vehicle;
- determining a power assisted gear position of the power steering assembly according to whether the direction changing wheel of the vehicle is the driving wheel, comprising:
- determining that a drive mode of the vehicle is a second all-wheel drive mode when the direction changing wheel of the vehicle is the driving wheel and the direction changing wheel is in a locked differential state;
- and
- determining that the power steering assembly is in a target power assisted gear position according to the second all-wheel drive mode of the vehicle;
- and
- controlling the power steering assembly to generate a power steering torque according to the power assisted gear position of the power steering assembly.
A power steering device, applied to a vehicle comprising a power steering assembly, the power steering device comprising:
- a controller configured to
- detect whether a direction changing wheel of the vehicle is a driving wheel, wherein the direction changing wheel of the vehicle is a front wheel or a rear wheel of the vehicle;
- determine a power assisted gear position of the power steering assembly according to whether the direction changing wheel of the vehicle is the driving wheel;
- and
- control the power steering assembly to generate a power steering torque according to the power assisted gear position of the power steering assembly;
- wherein the controller is specifically configured to:
- determine that a drive mode of the vehicle is a second all-wheel drive mode when the direction changing wheel of the vehicle is the driving wheel and the direction changing wheel is in a locked differential state;
- and
- determine that the power steering assembly is in a target power assisted gear position according to the second all-wheel drive mode of the vehicle.
