Abstract
First and second parameter maps used for vehicle vibration control are generated or updated. When generating or updating the first parameter map, an in-phase input for left and right wheels is calculated as the first parameter related to vertical motion of a reference point. The second parameter map is generated or updated at the same position as the position at which the first parameter map is generated or updated. In the generating or updating the second parameter map, an anti-phase for left and right wheels of the first and second wheels is calculated as the second parameter related to vertical motion of the reference point.
Claims7
A computer implemented method for managing a control map used for vibration control of a vehicle,
- wherein the control map includes first and second parameter maps,
- wherein the first and second parameter maps each represent a correspondence between a position and a parameter related to vertical motion of a reference point based on two or more wheel positions of the vehicle,
- wherein the method comprises generating or updating the first parameter map, and generating or updating the second parameter map for the same position as the position at which the first parameter map is generated or updated,
- wherein the generating or updating the first parameter map includes calculating (i) an in-phase input for left and right wheels derived from same vertical displacement of a first wheel and a second wheel as the first parameter related to vertical motion of the reference point, based on time series data of parameters related to the vertical motion of the first wheel and time series data of parameters related to the vertical motion of the second wheel, wherein the first wheel is one of a left wheel and a right wheel of the vehicle and the second wheel is the other of the left wheel and the right wheel of the vehicle,
- wherein the generating or updating the second parameter map includes calculating (ii) an anti-phase input for left and right wheels derived from different vertical displacements of the first wheel and the second wheel as the second parameter related to vertical motion of the reference point, based on the time series data of parameters related to the vertical motion of the first wheel and the time series data of parameters related to the vertical motion of the second wheel.
A system for managing the control map used for vibration control of a vehicle, comprising:
- one or more processors;
- and
- one or more memory devices in which the control map is stored,
- wherein the control map includes first and second parameter maps,
- wherein the first and second parameter maps each represent a correspondence between a position and a parameter related to vertical motion of a reference point based on two or more wheel positions of the vehicle,
- wherein the one or more processors are configured to execute processing to generate or update the first parameter map, and processing to generate or update the second parameter map for the same position as the position at which the first parameter map is generated or updated,
- wherein the processing to generate or update the first parameter map includes processing to calculate (i) an in-phase input for left and right wheels derived from same vertical displacement of a first wheel and a second wheel as the first parameter related to vertical motion of the reference point, based on time series data of parameters related to the vertical motion of the first wheel and time series data of parameters related to the vertical motion of the second wheel, wherein the first wheel is one of a left wheel and a right wheel of the vehicle and the second wheel is the other of the left wheel and the right wheel of the vehicle,
- wherein the processing to generate or update the second parameter map includes processing to calculate (ii) an anti-phase input for left and right wheels derived from different vertical displacements of the first wheel and the second wheel as the second parameter related to vertical motion of the reference point, based on the time series data of parameters related to the vertical motion of the first wheel and the time series data of parameters related to the vertical motion of the second wheel.
