The present invention relates to a method and an apparatus for controlling a car equipped with an automatic transmission having a lockup clutch. According to the control method of the present invention, when the lockup clutch is in the lockup state, a variation of a generated torque is detected. When the range of the torque variation detected exceeds a predetermined value, an engine torque is reduced by controlling the engine, and the automatic transmission is controlled to compensate for a reduction of the driving torque due to a reduction of the engine torque. Thus, the speed change ratio is changed to the low gear side. The control unit of the present invention includes a unit for controlling an output torque of an engine according to a command value, a unit for changing the transmission ratio of the automatic transmission, a unit for detecting a variation of the engine torque, a unit for deciding a target driving torque, a unit for reducing a torque command value when the range of a detected variation of the torque has exceeded a predetermined value when the lockup clutch was in the lockup state, and a unit for deciding a transmission ratio at which the reduction of the driving torque due to the reduction of the engine torque is compensated for.

In an attempt to accomplish an object to absorb a driving torque difference caused by a difference in a change gear ratio between before and after shifting and to reduce a shift shock, adopted is such a constitution that target driving torque characteristics with which said driving torque before and after shifting will become nearly equal are stored, and engine torque control will be effected according to said characteristics. The control device is so constituted that, during shifting, the engine torque is decreased to suppress a driving torque variation resulting from inertia variation, and the engine torque before a specific period from the completion of shifting is outputted higher than the normal torque, and the engine torque before a specific period from the completion of shifting is outputted higher than the normal torque to reset to the normal engine torque after the specific period after the completion of shifting.

The present invention can realize a vehicle running control apparatus including ACC function and map information data recording medium to obtain effective information for safety driving capable for running control meeting a driver's feeling. The first running speed is decided on the basis of the distance between the vehicles and the relative speed. The position detecting means detects the position of own vehicle on a map. The map information getting means gets road information, the width of the road, the radius of curvature, and slope on the basis of the map information. The visible distance estimating means estimates the visible distance on the basis of the map information, deciding the second running safety speed with the estimated visible distance. The running control means decides the object running speed of smallest one of the set speed, the first running speed, and the second running speed.
摘要:
When a throttle is fully open, a maximum torque set value is corrected based on the ratio between the maximum air volume set value under fully-open throttle conditions and the actual maximum air volume detected by an intake air volume meter such as an air flow sensor. Based on the corrected maximum torque set value, both the relation between the degree of accelerator opening and target torque and the relation between the target torque (target air volume) and the degree target throttle opening are corrected. Thus, even when various types of disturbances relating to torque error are generated, such as variations in air density generated in association with variations in temperature or altitude, variations over time such as contaminations of throttle chambers, or difference between machines such as engine bodies or auxiliary machines, it is possible to generate actual torque with respect to a target torque with a high degree of accuracy, while maintaining a desired relation between the degree of accelerator opening and the throttle opening.

A control device for giving an existing gear type transmission a parking lock function to lock a vehicle; a control method thereof; and an automobile having an improved transmission. The gear type transmission comprises a gear type speed change mechanism (5) provided with a mesh type clutch (3), and a second friction clutch (4) installed between the shafts of the speed change mechanism to enable torque transfer during shifting. A parking demand detecting means (9) detects the driver's parking demand. And, when it detects the driver's parking demand, a control device (10) sends an instruction signal to an actuator to instruct the latter to engage both the mesh type clutch (3) and the second friction clutch (4).
