Abstract
Provided is a vehicle behavior device including: a variable damper, which is provided between a vehicle body side and a wheel side of a vehicle, and is configured to adjust a force to be generated; a camera device configured to measure a road surface state forward of the vehicle; a future vehicle state estimation unit configured to predict a sprung behavior of the vehicle from a road surface displacement acquired by the camera device and a vehicle speed; and a command value calculation unit configured to obtain a force to be generated by the variable damper based on a predicted value obtained by the future vehicle state estimation unit, and output a command signal.
Claims8
A vehicle behavior device, comprising:
- a force generation mechanism, which is provided between a vehicle body side and a wheel side of a vehicle, and is configured to adjust a force to be generated;
- a road surface state acquisition unit configured to acquire a road surface state forward of the vehicle;
- a vehicle sprung behavior prediction unit configured to predict a sprung behavior of the vehicle from a road surface displacement acquired by the road surface state acquisition unit;
- and
- a force generation mechanism control unit configured to obtain a force to be generated by the force generation mechanism for reducing a vehicle sprung behavior such that a value of an evaluation function is minimized based on a predicted value obtained by the vehicle sprung behavior prediction unit, and to output a command signal.
