Suspension control apparatus and method for controlling a suspension control apparatus

A suspension control apparatus configured to control a suspension apparatus including a force generator configured to adjust a force between a vehicle body and a wheel of a vehicle, the suspension control apparatus comprising:

• a first instruction calculation portion configured to output a first target amount using a learning result acquired from machine learning in advance by inputting a plurality of different pieces of information;
• and
• a control instruction output portion configured to output a control instruction to the force generator based on the first target amount, the control instruction output portion being configured to limit the first target amount and output it as the control instruction in a case where the first target amount works in a direction leading to a vehicle state amount greater than a predetermined amount due to the control of the force generator based on the first target amount,
• wherein the vehicle state amount is a roll amount of the vehicle body, and
• wherein, in a case where the roll amount further increases due to the control of the force generator based on the first target amount when the vehicle is in a state that the roll amount is greater than a predetermined amount, the control instruction output portion limits the first target amount and outputs it as the control instruction.

• wherein the vehicle state amount is a pitch amount of the vehicle body, and
• wherein, in a case where the pitch amount further increases due to the control of the force generator based on the first target amount when the vehicle is in a state that the pitch amount is greater than a predetermined amount, the control instruction output portion limits the first target amount and outputs it as the control instruction.

• wherein the vehicle state amount is a vertical vibration amount of the vehicle body, and
• wherein, in a case where the vertical vibration amount further increases due to the control of the force generator based on the first target amount when the vehicle is in a state that the vertical vibration amount is greater than a predetermined amount, the control instruction output portion limits the first target amount and outputs it as the control instruction.

A method for controlling, with a suspension control apparatus, a suspension apparatus including a force generator configured to adjust a force between a vehicle body and a wheel of a vehicle, the suspension control apparatus including a first instruction calculation portion configured to output a first target amount and a second instruction calculation portion different from the first instruction calculation portion, the second instruction calculation portion configured to output a second target amount,

• the method comprising:
• a first step of outputting the first target amount output from the first instruction calculation portion using a learning result acquired from machine learning in advance by inputting a plurality of different pieces of information;
• and
• a second step of limiting the first target amount and outputting it as a control instruction to the force generator in a case where the first target amount works in a direction leading to a greater vehicle state amount than a predetermined amount due to output of the control instruction to the force generator on the first target amount, and
• a third step of outputting a value within a predetermined deviation relative to the second target amount as the control instruction, in a case where a deviation of the first target amount from the second target amount output from the second instruction calculation portion is greater than the predetermined deviation.
