Anti-pump-slip algorithm for hydraulic steering system

A method for operating a steering system of a vehicle, comprising:

• using a hydraulic steering system, controlling, in response to a steering input provided at a steering mechanism of the vehicle, a pump to control a steering device to steer the vehicle;
• sensing, at a sensor, an angle or position associated with the steering input provided at the steering mechanism;
• receiving, at an electric power steering system, a signal from the sensor and providing powered steering assistance to the hydraulic steering system based on the signal and a pump-slip offset associated with the pump;
• and
• determining the pump-slip offset, wherein the pump-slip offset corresponds to a difference between the angle or position associated with the steering input and an actual position of the steering device achieved by the pump.

A processing device configured to execute one or more instructions stored in memory, wherein executing the one or more instructions causes the processing device to:

• control a hydraulic steering system configured to, in response to a steering input provided at a handwheel of a vehicle, control a pump to control a steering device to steer the vehicle;
• receive, from a sensor, an angle or position associated with the steering input provided at the handwheel;
• control an electric power steering system to receive a signal from the sensor and provide powered steering assistance to the hydraulic steering system based on the signal and a pump-slip offset associated with the pump;
• and
• determine the pump-slip offset, wherein the pump-slip offset corresponds to a difference between the angle or position associated with the steering input and an actual position of the steering device achieved by the pump.
