Vehicle control system

The vehicle control system includes a braking force generating device () configured to generate a braking force to shift a load of a vehicle to a side of front wheels thereof at an initial stage of a cornering, and a control device () configured to control the braking force generated by the braking force generating device. The control device calculates an additional deceleration (Gxadd) according to vehicle state information, calculates a requested fore and aft acceleration (Gxr) according to a requested fore and aft force (Fxr) for the vehicle, calculates a correction coefficient (K) for weakening the additional deceleration according to the requested fore and aft acceleration, corrects the additional deceleration by the correction coefficient, and calculates an additional braking force (Fbadd) to be generated by the braking force generating device according to the corrected additional deceleration.

A control device includes an additional deceleration calculation unit that calculates an additional deceleration (G&#xd7;add) to be applied to the vehicle based on the steering angle, a target control amount calculation unit that calculates the control amount for the vehicle behavior changing device based on the additional deceleration, a rough road level calculation unit that calculates a rough road level of a road based on a wheel speed, and a control amount correction unit that corrects the control amount based on the rough road level, the rough road level calculation unit being configured to correct the wheel speed so as to remove a change thereof caused by the cornering maneuver of the vehicle, and to calculate the rough road level by using the corrected wheel speed.

A vehicle motion control system includes: a steering angle sensor for detecting a steering angle; a vehicle speed sensor for detecting a vehicle speed; a lateral acceleration sensor for detecting an actual lateral acceleration of a vehicle body; a reference lateral acceleration calculation unit configured to calculate a reference lateral acceleration from the steering angle and the vehicle speed; a required longitudinal force calculation unit configured to calculate a required longitudinal force for reducing a deviation of the actual lateral acceleration relative to the reference lateral acceleration; and a longitudinal force control unit configured to control an output of at least one of a brake and a power plant such that the required longitudinal force is generated.

A vehicle behavior stabilization system includes a yaw moment applying device configured to apply a yaw moment to the vehicle, a vehicle behavior stabilization control unit configured to selectively control the yaw moment applying device in such a way to stabilize a vehicle behavior according to a computed rear wheel slip angle in relation to a start threshold value and an end threshold value, and a threshold value correcting unit configured to correct the start threshold value and the end threshold value according to a change rate of the computed rear wheel slip angle and/or a change rate of a computed vehicle body slip angle.

Vehicle behavior stabilization system

At least a pair of electrodes comprising semiconductors or a semiconductor compounds are arranged to be submerged in water or a liquid of a hydrogen-containing organic compound. Applying pulse electric power between the at least one pair of the electrodes activates hydrogen atoms contained in the water or the hydrogen-containing organic compound to produce hydrogen gas. The hydrogen activating apparatus thus constructed eliminates the necessity of doping electrolysis or the like for improving an electric conductivity of the water and allows production of hydrogen from materials containing hydrogen atoms such as water and the hydrogen-containing compound or the like with a low energy.
