摘要： An acceleration detection device for detecting detected acceleration of a vehicle is provided with a stopped acceleration detector, an acceleration change detector, an acceleration estimating unit and a correcting unit. The stopped acceleration detector detects a detected stationary acceleration value when the vehicle is stopped on a sloping road based on an acceleration sensor signal from an acceleration sensor mounted on the vehicle. The acceleration change detector detects an acceleration change associated with the vehicle transitioning from a stationary state to a driving state on the sloping road based on the acceleration sensor signal. The acceleration estimating unit estimates an estimated stationary acceleration value based on the acceleration change that was detected by the acceleration change detector. The correcting unit corrects the detected stationary acceleration value based on a deviation between the estimated stationary acceleration value and the detected stationary acceleration value.

摘要： An engine rotational speed control apparatus is provide to prevent a degradation of fuel efficiency caused by an unnecessary increase of the rotational speed of an engine when a depression amount of an accelerator pedal is briefly increased and then immediately decreased. In particular, when the vehicle is accelerated, an optimum fuel efficiency operating point along an optimum fuel efficiency curve is not moved immediately to another optimum fuel efficiency operating point corresponding to a new target drive force. Instead, the target drive force is reached by increasing the engine load while increasing the engine rotational speed as little as possible, and thus using an operating point that does not lie on the optimum fuel efficiency curve.

摘要： A shift control apparatus for a continuously-variable transmission includes an operating condition sensing section; a normal-time speed ratio determining section; a normal-time control section; a kickdown-acceleration request determining section; a kickdown-acceleration-time control section; and an accelerator-operation-quantity variation-rate limiting section. The kickdown-acceleration-time control section is configured to set a kickdown-acceleration-time target speed ratio in accordance with a vehicle speed and an accelerator operation quantity, to cause an output rotational speed of the transmission to increase substantially linearly with an increase of input rotational speed of the transmission, when the kickdown-acceleration request determining section determines that a kickdown acceleration request is present, and to control the speed ratio in accordance with the kickdown-acceleration-time target speed ratio. The accelerator-operation-quantity variation-rate limiting section is configured to calculate a corrected accelerator operation quantity by imposing a limitation on a variation rate of the accelerator operation quantity, when a predetermined variation of the sensed accelerator operation quantity occurs during the speed ratio control of the kickdown-acceleration-time control section, and to output the corrected accelerator operation quantity to the kickdown-acceleration-time control section in order to set the kickdown-acceleration-time target speed ratio.
