A driving force distribution and controlling apparatus and method for a vehicle is disclosed by which control interference which may occur between control by a driving force distribution mechanism and control by an antiskid brake system (ABS) is suppressed while the behavior of the vehicle is stabilized.

Driving force distribution and controlling apparatus for vehicle and driving force distribution and controlling method for vehicle

When a brake pedal is operated by the vehicle driver, and detection signals from hydraulic pressure sensors and a brake switch, for detecting pressure of the brake pedal, are supplied to an ECU, the ECU performs a determination according to the detection signals as to whether or not the hydraulic pressure PM is a maximum pressure gradient d(PM)/dtmax. When the determination result of the braking condition is an emergency braking condition, an intake valve is opened. Thereafter, atmosphere is forcibly supplied to atmospheric chambers of a booster, to assist the braking force.

Braking apparatus and braking method for vehicle

A control apparatus for controlling the output of a vehicle equipped with an internal combustion engine. The control apparatus includes a torque control unit and an electronic control unit, is electrically connected to various sensors for detecting the running conditions of the vehicle, and is capable of controlling, e.g., the operations of a throttle valve and an ignition plug, to thereby control the driving torque of the engine. The control apparatus calculates a reference driving torque of the engine on the basis of the vehicle speed, and also calculates a slippage of the driving wheels on the basis of a deviation of peripheral speed between the driving and driven wheels. A correction torque for the reference driving torque, which is calculated by the control apparatus on the basis of the detected slippage, is subjected to restriction in accordance with the vehicle running conditions, and the reference driving torque is corrected in accordance with the restricted correction torque, to obtain a target driving torque. Thus, the control apparatus controls the operations of the throttle valve and ignition plug such that the actual driving torque of the engine coincides with the target driving torque.

An output control apparatus for a vehicle includes a torque reduction device for reducing driving torque of an engine independent of manipulation by the driver and a vehicle speed detection device for detecting a vehicle speed. It further includes a reference driving torque setting device for setting a reference driving torque according to the vehicle speed detected by the vehicle speed detection device. A reference torque setting device is further included for setting a reference driving torque according to a slip amount of the driving wheels. A target driving torque setting device is further included for setting a target driving torque from the reference driving torque set by the reference torque setting device according to a peripheral speed of the driving wheels. A torque control unit is also included for controlling operation of the torque reduction device so that the driving torque is that of the target driving torque set by the target driving torque setting device. Finally, a turning correction device is included for correcting the target driving torque according to the steering angle, to adequately control the driving force of the vehicle during turning, separately from that of straightforward traveling, thereby enabling safe and smooth traveling of the vehicle.

Output control apparatus for vehicle

An output control apparatus for a vehicle which includes a torque reduction device for reducing driving torque of an engine independent of manipulation by the driver and a filter device for outputting a corrected longitudinal direction acceleration, varying according to changes in longitudinal direction acceleration of the vehicle body with a predetermined delay time and maintaining the output during a speed shift above the value immediately before the speed shift. A reference torque setting device is further included for setting a reference driving torque according to a slip amount of the driving wheels. A target driving torque setting device is also included for correcting the reference driving torque according to the slip amount of the driving wheels to set a target driving torque. Finally, a torque control unit is included for controlling operation of the torque reduction device so that the driving torque is that of the target driving torque set by the target driving torque setting device, thereby preventing a stalling feeling of the vehicle immediately after the speed shift, and improving the acceleration feeling.
