Sensor system for dynamic control of vehicle - has pair of sensors straddling each axis and with central processor

Pairs of sensors are mounted each side of each of the three axes through the centre of gravity of the vehicle. The sensor outputs are collected by a central processing unit and the rotational and linear movements about and along each axis are computed. This enables the vehicle dynamics to be controllled, e.g. steering, active suspensions etc. The sensor pairs are directed in opposite ways and thus together provide the required information for each axis. The system can compute the dynamic condition for any selected point of the vehicle to enable, e.g. the separate suspension elements to be controlled. USE/ADVANTAGE - Predicting behaviour of motor vehicle. Centrallised control; min. of sensors; active dynamic control.

Vehicle suspension system with variable-damping force shock-absorbers - has dead zone in stepping-motor control whose boundaries are raised and lowered according to measured vertical velocity

Each shock-absorber (SA) incorporates a reservoir chamber between oil-filled coaxial cylinders and is adjusted by a stepper motor (3) under central control (4) responsive to the signals from vertical accelerometers (1) at associated points on the bodywork. The controller incorporates a dead-zone circuit whereby the damping characteristics of the shock-absorbers are adjusted to their min. only while the control signal remains within a dead zone for the vertical velocity, whose magnitude governs the variation of upper and lower bounds of the dead zone. ADVANTAGE - The life of the system is extended and its energy consumption reduced by prevention of unnecessary reaction to insignificant fluctuations in e.g. high-speed travel over a straight dry road.

DEVELOPMENT AND ENHANCEMENT OF A SMART AND ACTIVE FOUR-WHEEL SUSPENSION SYSTEM

Abstract This innovation is about designing, creating, assessing and evaluating an adjustable suspension device for a vehicle. This system is designed to improve car performance from rough to flat surfaces in all field conditions. A adjustment to the double-triangle four-bar connecting suspension completes the proposed design. The changes allow the upper links of the suspension system, in order to meet operator's requirements, to adjust vertical location on the fly. The change of location changes the suspension geometry of the vehicle; in particular the anti-squatter that affects the slope of the vehicle and consequently traction. Traction is also directly regulated by the suspension system modification. We have extensively tested the effects of the adjustable suspension system through film motion analysis of a prototype vehicle before and after the proposed design amendments. Future implementations of this design should boost cars of all sizes, from mobile robots to vehicles. The results ...
