  • Patent number: 10538267
    Abstract: An embodiment of a system of a vehicle includes a power steering system that operates as commanded by control commands, and a control module configured to receive a first control command. The control module is also configured to generate a range signal indicative of a range of command values based on a plurality of input signals, generate a second control command based on a subset of the plurality of input signals, determine whether the first control command is out of the range for longer than a predetermined duration of time, and send the second control command to the power steering system in response to determining the first control command is out of the range for longer than the predetermined duration of time.
    Type: Grant

  • Patent number: 9598102
    Abstract: A method of mitigating abnormalities in a first control command for controlling a power steering system is provided. The method generates a range signal indicative of a range of command values based on a plurality of input signals. The method determines whether the first control command is out of the range for longer than a predetermined duration of time. The method limits the first control command to the range and sends the limited first control command to the power steering system in response to determining that the first control command is out of the range for shorter than or equal to the duration of time.

  • Patent number: 8630771
    Abstract: The invention relates to a control method for a steering system with electric power assistance, comprising a steering wheel, an electric power assist motor, an electric control unit, which includes a memory for storing digital data, a motor driver unit which based on a target engine torque that is delivered to the motor driver unit, determines and sends out electrical signals for controlling the electric power assist motor, at least one sensor device for determining a control variable introduced into the steering wheel, for example a manual torque, wherein in the control unit with the help of the control variable a preset value is determined for a engine torque of the power assist motor, characterized in that in the memory an upper threshold value for the target engine torque is stored and for a case A, in which the preset value exceeds the upper threshold value, the control unit sends out the upper threshold value as the target engine torque to the motor driver unit and in a case B, in which the preset value
