Control system for ride characteristics of motor vehicle - corrects estimated characteristic index in accordance with control signal dependent on ride, movement and route evaluations.

摘要

The state of ride is identified by detectors of steering wheel position (33), vehicular acceleration (34) in terms of throttle flap position, and brake pedal pressure (35). The conditions of motion are assessed from yaw rate (31) and road speed (32). A microprocessor (37) operates on these inputs and other from a decimal keyboard (38a) and changeover switch (38b) used for entry of learning data and renewal of combination coeffts. and threshold values in a parameter memory (37e). A driver circuit (39) operates an electric control (21) of the rear wheel steering. USE/ADVANTAGE - In a vehicle equipped with four-wheel steering, a neural net affords precise control of ride.
