Filed: 2000-03-07
Abstract: PROBLEM TO BE SOLVED: To control a vehicle according to road conditions by deciding the upper limit of the shift gear stage based on the curvature radius of a corner from road information and the vehicle speed, deciding the upper limit of the shift gear stage according to the road gradient, and setting the shift gear stage within a range of the lower one. SOLUTION: A corner curvature radius is found from the road information of a navigation processing part 11, and the means curvature and the altitude change rate are found by the distance from the own vehicle position to the corner entrance. Secondly, the vehicle speed, a shift mode, etc., are obtained by a vehicle state detection part 30, etc., and the upper limit shift gear stage is decided based on the distance, the corner curvature radius, and the vehicle speed by a corner control shift decision routine. Thirdly, when the altitude change rate is a reference value or more by a zone control shift decision routine, the mode is changed to a power mode, and when it is not more than that, the present shift mode is held and the upper limit of the shiftable shift gear stage is decided from the means curvature and the vehicle speed.  Lastly, the upper limit shift gear stage is set to one lower than the present one by a slope control shift decision routine and the upper shift gear stage is set to the lowest one from among the respective upper shift gear stages. The shift gear stage set control can be thus performed according to the road conditions.
