The purpose of this study is to research the feasibility of an integrated autombile control system, which has various control functions realized by conventional 4WS, ABS, etc. For this purpose we developed a new drive control system in which front wheels are driven by an engine, while rear wheel are driven by two electric motors. Yaw rate control yields additional moment by drive force differrence between two rear wheels. Slip control regulates the slip ratio of each rear wheel. Motor control executes high speed torque control. These controls are performed by a sophisticated multi-microprocessor system. The following results have been derived; (1) The robustness against disturbances caused by external forces was improved. (2) The acceleration and braking capabilities on low friction roads were improved. (3)The cornering stability on low friction roads was augumented by distributing the driving forces appropriately onto three drive axles.In conclusion, this study has revealed that various automobile control functions can be integrated in a single mechanism by means of independent wheel drive system.
