Abstract: A device for controlling a braking force of the vehicle has a braking force boosting control portion that increases the braking force in response to a detection of a possibility of a collision with an obstacle in the driving course of the vehicle, and a boost-reducing control portion that controls the boosting control portion so as to reduce the braking force when a steering operation is executed by a driver of the vehicle as compared to a braking force to be generated when no steering operation is executed. The braking forces on individual wheels are reduced depending upon the lateral force on the corresponding wheel. In the device, the precrash safety braking operation does not interfere with the steering operation of the driver so that the steering controllability may be ensured while the vehicle is slowed down.

Abstract: 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.

Abstract: A deceleration control apparatus for a vehicle provided with a brake system for generating braking force in the vehicle, and a transmission, controls the brake system and the transmission such that a deceleration acting on the vehicle matches a target deceleration set as a deceleration to be applied to the vehicle by a brake operation of the brake system and a shift operation which shifts the transmission into a relatively low speed or speed ratio.

Abstract: A follow distance control apparatus controls a follow distance without giving an uncomfortable feel to a driver during a deceleration control regardless of a selected control mode. A front-vehicle running ahead of an own-vehicle is detected by a sensor such as a radar. A deceleration apparatus, which decelerates the own-vehicle, is controlled by a controller based on an output signal of the sensor. The controller controls the deceleration apparatus according to selected one of a short distance control mode and a long distance control mode. In the short distance control mode, an actual value of the following distance is controlled to be shorter. In the long distance control mode, the actual value of the following distance is controlled to be longer.

Abstract: A new and novel device for controlling a braking force of the vehicle comprises a braking force boosting control portion that increases the braking force in response to a detection of a possibility of a collision with an obstacle in the driving course of the vesicle; and a boost-reducing control portion that controls the boosting control portion so as to reduce the braking force when steering operation is executed by a driver of the vehicle as compared to a braking force to be generated when no steering operation is executed. The braking forces on individual wheels are reduced depending upon the lateral force on the corresponding wheel. In the device of the present invention, the preclash safety braking operation does not interfere with steering operation of the driver so that the steering controllability may be ensured while the vehicle is slowed down.
