Abstract
A controller as a control apparatus controls a shock absorber of a control target wheel (a rear wheel) located in back of a detection target portion (a front wheel) of an unsprung acceleration sensor based on a detection value detected by the unsprung acceleration sensor on the front wheel side provided on a vehicle. In this case, the controller identifies a movement distance (a delay distance) from the detection target portion (the front wheel) and controls the shock absorber of the control target wheel (the rear wheel) located in back thereof based on the detection value of the unsprung acceleration sensor and a vehicle speed for each control period.
Claims6
A control apparatus configured to, based on a detection value detected by at least one vehicle behavior detection portion provided on a vehicle, control a force generation mechanism of a control target wheel located in back of a detection target portion of the vehicle behavior detection portion by a predetermined length,
- wherein the control apparatus is operable to
- identify a movement distance from the detection target portion per the control period of the detection value,
- store the detection value per distance by dividing the predetermined length by a predetermined step size,
- shift the stored detection value by a predetermined distance corresponding to the movement distance,
- refer to the detection value in one of positions where the shifted distance corresponds to the predetermined length, and
- control the force generation mechanism of the control target wheel located in back of the detection target portion, based on the control period of the control apparatus and a vehicle speed for the control period,
- wherein the stored detection value is shifted by the number of regions according to a quotient resulting from dividing the movement distance by the step size, and a remainder of the division is added to the movement distance identified at the time of a next control period in the control period.
