Title: Dynamic, hysteresis-free control of vehicle horizontal level - using one computer to control level on straights and round bends and another to control force distribution during braking
Inventor: KLAUE HERMANN DR ING
IPC: B60G17/016
Filed: 1989-12-18
Abstract: Dymnamic, hysteresis-free control of the horizontal level of a motor vehicle involves sensors working in the longitudinal and transverse directions which control the level during travel in a straight line and round turns via one computer unit.

Title: Anti-skid brake control system - has continuously variable characteristics to match braking to vehicle dynamics
Inventor: MASAKI SHOUICHI
IPC: B60T8/62
Filed: 1990-07-11
Abstract: The anti-skid control system has wheelspeed monitors and a proce-ssor to determine the blocking state of each wheel w.r.t. wheelspeed , and the speed of the vehicle.
