Title: Control device for internal combustion engine
Inventor: KAKIHARA TAKAYUKI
IPC: F02D45/00
Filed: 2000-06-16
Abstract: PROBLEM TO BE SOLVED: To improve fuel economy and emission, by setting a cut space of a map calculating various control quantities for controlling an internal combustion engine, in accordance with a combustion form and an operating condition. SOLUTION: As a combustion form and an operating condition of an internal combustion engine, whether specific stratified combustion (step S102), homogeneous lean combustion (step S104), or ordinary homogeneous combustion are during execution or not is decided. Of a plurality of maps having a different cut space in accordance with these combustion form and operating condition, the necessary map is selectively used. Here when a fine conformed value is necessary, various control quantities are calculated based on the map with the fine cut space (step S103, step S105). That is, by giving a memory capacity and man-hours to only a map with a fine cut space necessary of a plurality of the maps, a more suited operating condition of the internal combustion engine can be attained by the small memory capacity and small man-hours, as a result fuel economy and emission can be improved.

Title: Traction controller for vehicle
Inventor: HOSOMI SOJI
IPC: B60T8/175
Filed: 2000-06-27
Abstract: PROBLEM TO BE SOLVED: To effectively and surely reduce an unfavorable influence to an engine and a drive system resulting from traction control, and effectively restrain drive slippage. SOLUTION: A pressure variation ΔPi of braking pressure is computed based on an acceleration slippage ΔVwi of wheels and a wheel acceleration αwi (S20-40). In the traction control and an increasing process of braking force, an upper limit pressure increase ΔPmaxi of the braking force is computed to get small as an engine speed Ne or an estimated value Pbi of the braking force gets high based on thereon (SH50-70), and the upper limit increase ΔPmaxi of the braking force is corrected to be brought to a higher value as a reduction ratio of a transmission 14 is low (S80, 90). The variation ΔPi of the braking force is limited to the upper limit increase ΔPmaxi in a condition where the pressure variation ΔPi of the required braking force is too high and where the increase of the braking pressure is to be limited (S100, 110).
