TL;DR: In this paper, a determining function of which the sign varies when the slip ratio is equal to the target value, and a switching function comprising a time integral of the determining function, are set, and the drive torque target value is set such that it is directly proportional to the switching function.

TL;DR: In this paper, a damping force controller of a suspension system which can precisely damp sprung vibration by exhibiting a dampening force characteristic that takes into consideration either a vertical vibration characteristic or a pitching characteristic according to the operating condition of the suspension system is presented.

TL;DR: In this article, a damping force variable shock absorber is equipped with a target value setting means 15 for setting a specified constant, that is, a basic damping constant target value, and with a correction value operating means operating a clamping constant correction value out of an ideal clamping force operated based on relative speeds and relative displacements.

TL;DR: In this article, the authors proposed a method to make the behavior of a vehicle stable and to shorten a braking distance when the brakes are applied to the vehicle by calculating braking torque based on the value of a judgement function for changing a sign when the slip ratiocoincides with the aiming value and by adding correction responsive to the angular acceleration of the wheel to the aim value.

TL;DR: In this paper, the drive torque regulation device detects the velocity of the driven wheels and the car's velocity and calculates the corresponding drive slip from the detected velocities, for regulation of drive torque until the slip factor reaches a given value.
