Patent number: 6704641Abstract: Automotive control system designed to control a plurality of controlled elements installed in the vehicle is provided. The control system includes control circuits and a manager circuit. The control circuits are designed to perform given control tasks using pre-defined controlled variables. The manager circuit is designed to determine a target value of a preselected output parameter of at least one of the controlled elements in the form of a second controlled variable different from one of the controlled variables employed in the control circuit for the one of the controlled elements. The control system also includes an adaptor designed to translate the second controlled variable indicative of the target value of the output parameter into a value of the corresponding controlled variable.

Patent number: 6466851Abstract: In a vehicle control system of this invention, a CVT ECU does not executes the calculations such as a gear ratio, etc., but simply controls the gear ratio of a CVT on the basis of the target gear ratio and a CVT input torque transmitted from a manager ECU by way of a communication line. Accordingly, when mounting a CVT unit constructed with the CVT and the CVT ECU in a vehicle, the vehicle control does not need to tune the CVT ECU one by one, even though the types and engines of vehicles are varied. Therefore, it is possible to configure the CVT unit independently of the types of vehicles, which achieves standardization or generalization of the CVT unit in terms of both the hardware and the software.Type: GrantFiled: June 8, 2001Date of Patent: October 15, 2002Assignee: Denso CorporationInventors: Yoshifumi Kato, Tsutomu Tashiro, Noboru Miyamoto, Takehito Fujii
