Abstract:
A behavior control apparatus for a vehicle is disclosed which allows a driver to select permission or inhibition of control. The apparatus includes a braking control section for performing, when the vehicle behavior detected is displaced to the behavior instability side with respect to a control start reference, braking control to stabilize the vehicle behavior, and an engine output suppressing control section for performing, when the vehicle behavior detected is displaced to the behavior instability side with respect to another control start reference, control to suppress the engine output power to stabilize the vehicle behavior. If it is selected by a selection section that the engine output suppressing control should be inhibited, then the engine output suppressing control is inhibited, and further, if it is decided by a decision section that the driver has an acceleration intention, then the braking control for the stabilization of the vehicle behavior is ended.
Abstract:
A drive controller for hybrid vehicles, the hybrid vehicle comprising: an engine; a motor which is able to assist the driving force from the engine; an automatic clutch mechanism which is able to engage/disengage the transmission of the driving force between the engine and the motor; an automatic transmission disposed downstream of the motor; a filter for collecting particulates in exhaust gas; and a controller for controlling operations of these devices, wherein the controller operates in such a way that, for regenerating the filter, the idling speed while the vehicle is halted is set higher, and the predetermined rotational speed for initiating the clutch engagement is set higher than the rotational speed at the time of non-regeneration of the filter in light of increase in the engine rotational speed for the fast-idle control.
Abstract:
A hybrid electric vehicle is arranged such that a driving force of an electric motor can be transmitted to driving wheels and that a rotary shaft of the electric motor can be coupled with an output shaft of an engine. The vehicle comprises a starter motor provided separately from the electric motor, an electric power source provided separately from a battery that supplies power to the electric motor, to supply power to the starter motor, and a braking force maintaining device configured to be activated by power from the power source to maintain a braking force on the vehicle. When a request for starting the engine is made, if a specified abnormal condition which makes the starting of the engine by the electric motor impracticable is detected, an ECU causes the engine to be started by the starter motor when the braking force maintaining device is not active.
Abstract:
The invention provides a roll-over suppressing control apparatus for a vehicle which can suppress roll-over of the vehicle sufficiently also upon steering back turning wherein the turning direction of the vehicle changes over halfway. The roll-over suppressing control apparatus includes a roll-over suppressing control section for controlling, if a roll rate sensor detects that, upon turning of the vehicle, the vehicle is in an excessive rolling state, a braking mechanism so as to apply or increase braking force to a turning outer wheel to perform roll-over suppressing control. If a decision section decides during the roll-over suppressing control that all of the left and right wheels of the vehicle remain in contact with the road, then the roll-over suppressing control section carries out all wheel braking control of controlling the braking mechanism so as to apply the braking force to all of the left and right wheels of the vehicle.

Abstract:
The invention provides a technique for learning a stability factor of a vehicle by which the stability factor of the vehicle can be calculated in response to a state of the vehicle. To this end, a state of the vehicle during traveling is detected, and it is decided based on the detection information whether or not the current traveling state of the vehicle is a stable turning state. If it is decided that the current traveling state of the vehicle is a stable turning state, then the stability factor of the vehicle is calculated in accordance with a predetermined arithmetic operation expression based on a vehicle speed, a steering angle and a yaw rate detected during traveling, and the calculated value is determined as a learned value of the stability factor of the vehicle thereby to determine the stability factor in the current state of the vehicle.
Abstract:
The invention provides a roll-over suppressing control apparatus for a vehicle wherein appropriate braking force can be applied to a turning outer wheel in response to a situation and a rolling state of the vehicle to suppress otherwise possible roll-over of the vehicle while assuring the traveling performance. A roll parameter value detection section detects a parameter value corresponding to a rolling state of a vehicle, and a turning type decision section decides a type of turning of the vehicle. A roll-over suppressing control section controls a braking mechanism in a predetermined period so that, when the rolling state of the vehicle upon turning of the vehicle is excessive with respect to a first reference state, an amount of braking force corresponding to the magnitude of the roll parameter value and the type of turning. By the control, while the traveling performance of the vehicle is assured, roll-over of the vehicle can be suppressed effectively to assure the stability of the vehicle.

Abstract:
A roll-over suppressing control apparatus for a vehicle is disclosed which can carry out roll-over suppressing control appropriately in response to the type of turning. Upon turning of the vehicle, if a parameter corresponding to the rolling behavior of the vehicle becomes higher than a control start criterion value set in advance, then roll-over suppressing control of suppressing rolling of the vehicle is started. Then, if the parameter becomes lower than a control end criterion value set in advance, then the roll-over suppressing control is ended. As the control end criterion value, a steady turning control end criterion value is used when the turning of the vehicle is steady turning, but when the turning of the vehicle is non-steady turning such as lane change turning, a non-steady turning control end criterion value set to a value lower than that of the steady turning control end criterion value is used.
