Abstract
The output signals of sensors, which sense the operations of the driver of a vehicle, are input to a central control unit which determines, based thereon, the operating conditions of the driver and generates, as a result of such determination, instruction signals to a power controller for controlling an engine, a transmission, etc., and a drive controller for controlling a steering system, a suspension system, a brake system, an air conditioner, etc., in a comprehensive way. The controllers are also directly connected to the sensors so that they can control the corresponding control means independently of the central control unit. The controllers generate instruction signals to the corresponding control means, which are sub-systems of the total system, so that actuators provided on the respective control means are thereby controlled to operate in conjunction with all the control means through the intermediary of the respective controllers, while priority is given to an instruction from the central control unit. The control means are each provided with sensors in addition to an actuator so that if there is a fault in the data transmission line between the central control unit and the respective control means, the individual control means can properly control the corresponding actuators based on the output signals of the corresponding sensors provided thereon so as to ensure continued travel of the vehicle.
