Electric vehicle regenerative antiskid braking and traction control system

TLDR
In this paper, an antiskid braking and traction control system for an electric or hybrid vehicle having a regenerative braking system operatively connected to an electric traction motor, and a separate hydraulic braking system includes one or more sensors for monitoring present vehicle parameters and a processor, responsive to the sensors, for calculating vehicle parameters defining the vehicle behavior not directly measurable by the sensors and determining if regenerative anti-skid braking control, requiring hydrualic braking control or requiring traction control are required.
Abstract
An antiskid braking and traction control system for an electric or hybrid vehicle having a regenerative braking system operatively connected to an electric traction motor, and a separate hydraulic braking system includes one or more sensors for monitoring present vehicle parameters and a processor, responsive to the sensors, for calculating vehicle parameters defining the vehicle behavior not directly measurable by the sensors and determining if regenerative antiskid braking control, requiring hydrualic braking control, or requiring traction control are required. The processor then employs a control strategy based on the determined vehicle state and provides command signals to a motor controller to control the operation of the electric traction motor and to a brake controller to control fluid pressure applied at each vehicle wheel to provide the appropriate regenerative antiskid braking control, hydraulic braking control, and traction control.

Brake control system

TL;DR: In this article, a target braking force to a normal brake apparatus is calculated on the basis of a result of detection by a malfunction detecting portion, in such a way that a total of braking forces generated in the brake apparatuses in respective wheels becomes as equal as possible to a requested braking force, at a time when a malfunction is generated in either a brake apparatus or a braking force control portion.
