摘要:
A deceleration control apparatus for a vehicle, which performs deceleration control on the vehicle by an operation of a brake system that applies a braking force to the vehicle and a shift operation which shifts a transmission of the vehicle into a relatively low speed or speed ratio, changes, as the deceleration control, the braking force applied to a non-driven wheel of the vehicle and the braking force applied to a driven wheel of the vehicle based on a deceleration F applied to the vehicle and an engine braking force Fe that acts on the driven wheel of the vehicle. The engine braking force includes inertia force and changes in the engine braking force produced by a shift, as well as engine braking force produced as a result of the accelerator being turned off.

A declaration control apparatus and method for a vehicle, which performs deceleration control such that a deceleration acting on the vehicle becomes equal to a target deceleration by an operation of a brake system which applies a braking force to the vehicle and a shift operation which shifts a transmission of the vehicle into a relatively low speed or speed ratio, increases the target deceleration over time at a predetermined gradient to a predetermined value when a determination that there is a need to shift the transmission into a relatively low speed or speed ratio has been made, and after the target deceleration reaches the predetermined value, maintains the target deceleration at a generally constant value. As a result, a deceleration transitional characteristic of the vehicle is able to be improved.

摘要:
A target deceleration for running on a curved road ahead of a vehicle is obtained, based on a driver's intention which is input or estimated, and a driver's driving skill level which is input or estimated; and deceleration control is performed so that deceleration applied to the vehicle becomes equal to the target deceleration. In a case where the driver's intention is to cause the vehicle to respond to driving operation relatively quickly, the target deceleration may be set to a relatively small value; and in a case where the driving skill level is relatively high, the target deceleration is set to a relatively small value. Further, the target deceleration is decided based on a state of a road where the vehicle runs.

In a deceleration control method for a vehicle, by which deceleration control of the vehicle is performed based on a distance between the vehicle had an obstacle including a preceding vehicle ahead of the vehicle, a target deceleration at which the vehicle is to be decelerated is obtained based on the distance; a speed or speed ratio that will apply a deceleration equal to, or less than, the target deceleration to the vehicle is selected as the speed or speed ratio of a transmission of the vehicle during a shift operation; and the deceleration control is executed by an operation of a brake system which applies a braking force to the vehicle and a shift operation which shifts the transmission of the vehicle into a relatively low speed or speed ratio.

It is an object of the invention to provide a shift control apparatus which does not cause a vehicle driver to feel uncomfortable when shift control means resumes normal shift control using a predetermined shift pattern. Where return-to-normal determining means 105 determines that a condition or conditions under which the shift control means 102 resumes shift control using a MEDIUM MODE shift pattern is/are satisfied, return-to-normal permitting means 116 permits the shift control means 102 to resume the shift control using the MEDIUM MODE shift pattern when an output control member release determining means 108 determines that an accelerator pedal 58 has been released. In this arrangement, the driver does not feel uncomfortable even if the transmission is shifted up immediately after the shift control means 102 resumes the shift control using the MEDIUM MODE shift pattern.

A deceleration control apparatus for a vehicle including a controller that performs deceleration control based on a first target deceleration set based on a distance to a starting point of an upcoming curve, when the deceleration control for the curve is started at a position distant from the starting point of the curve; and that performs the deceleration control based on a second target deceleration set based on a lateral acceleration that is estimated to be detected when the vehicle passes the starting point of the curve, when the deceleration control for the curve is started at a position close to the starting point of the curve. With this apparatus, it is possible to perform the deceleration control that provides drive assist according to the intention of the driver and that enhances driving convenience for the driver.

A deceleration control apparatus and method for a vehicle, which performs deceleration control on the vehicle by an operation of a brake system which applies a braking force to the vehicle and a shift operation which shifts a transmission of the vehicle into a relatively low speed or speed ratio, performs the shift operation and the operation of the brake system such that a target deceleration set based on a curvature or curvature radius of a curve in a road ahead of the vehicle, a distance to the curve, and a vehicle speed, acts on the vehicle. As a result, a desired deceleration according to the distance to the curve is able to be applied to the vehicle.

A lock-up clutch slip control system for controlling a lock-up clutch, which is arranged in parallel with a hydraulic power transmission for connecting a prime mover and a speed change unit, selectively into a slip state. It is decided whether or not a slip control of changing the lock-up clutch from a complete apply state to a slip state is to be executed according to the operation of lowering the output of the prime mover. The output of said prime mover is changed to suppress the output fluctuation of the prime mover when it is decided that the slip control of the lock-up clutch is to be executed.
摘要:
In a driving force control apparatus and a driving force control method, a curve ahead of a vehicle is detected; a target vehicle speed is set to pass the curve; a starting-point shift speed is set to pass the starting point of the curve; and an end-point shift speed is set to pass the end point of the curve. After a shift speed is changed to the starting-point shift speed, it is determined whether an additional engine brake is required at the starting-point shift speed. If it is determined that the engine brake is not required, the shift speed is changed to the end-point shift speed. Alternatively, if a vehicle speed is lower than or equal to a value corresponding to the target vehicle speed after the shift speed is changed to the starting-point shift speed, the shift speed is changed to the end-point shift speed.
