The electro-dynamically controlled leveling system includes a central control module in electrical communication with the one or more sensors and the one or more electro-pneumatic valves. The central control module receives the sensory input from the one or more sensors, calculates a dynamic condition of the vehicle based on the sensory input, determines a desired air pressure for each air spring based on the calculated dynamic conditions of the vehicle, and transmit a command to the electro-pneumatic valves to adjust the air pressure of the air springs.

摘要： A powertrain control ECU sets a target driving force, and controls an internal combustion engine and a transmission of a vehicle. A first processor of the powertrain control ECU includes a driving force adjustment portion, a filter, a mode-switch, an environmental information-obtaining device, and a steering sensor. The driving force adjustment portion sets the target driving force based on at least one of instructions from a driver and from a second processor. The filter corrects the target driving force to suppress vibration on a spring of the vehicle. The mode-switch sets the running mode. The environmental information-obtaining device obtains information on the environment around the vehicle. The steering angle sensor determines the running condition. A correction amount, by which the filter corrects the target driving force, is adjusted according to the running mode, the environment, and the running condition.

摘要： An apparatus for estimating a road traffic condition and for controlling a vehicle running characteristic includes a controller having a fuzzy inference function and a neural network function. The controller carries out frequency analysis on vehicle driving parameters such as vehicle speed, steering angle, accelerator opening degree, and longitudinal acceleration and lateral acceleration of a vehicle, to thereby determine a mean value and variance of each parameter. It implements fuzzy inference based on a traveling time ratio, an average speed, and an average lateral acceleration, which are obtained from vehicle speed and/or steering angle, to thereby calculate road traffic condition parameters, including a city area degree, a jammed road degree, and a mountainous road degree. According to the neural network function, the controller further determines an output parameter, indicative of the vehicle maneuvering state, by subjecting the mean value and variance of the vehicle driving parameters and the weighted total sum of the road traffic condition parameters to nonlinear conversion. Then, it variably controls the operating characteristic of a vehicle-mounted apparatus such as a rear-wheel steering controlling unit in accordance with the output parameter, thereby variably controlling the vehicle running characteristic.

摘要： A discriminating value approximately corresponding to the amount of a change in mean effective pressure is calculated on the basis of the revolution period of an internal combustion engine, and a cause for the vibration of the vehicle and conditions in driving on a rugged road are indirectly detected from a misfire-originated change in engine torque. The natural frequency of the suspension of the vehicle with the internal combustion engine mounted thereon is adjusted based on the result of the detection, thereby automatically preventing comfortable riding from being deteriorated by a misfire-originated change in torque or by a drive on a rugged road.

摘要： A suspension control apparatus and a method for a vehicle having a plurality of suspension units each disposed between a road wheel and the body of a vehicle for suspending the corresponding road wheel from the vehicle body. The suspension control apparatus includes a control unit which is connected to receive the output signals from an acceleration sensor, a vehicle-speed sensor and a steering sensor for calculating the rolling state of the vehicle due to a transverse acceleration thereof and controlling the respective suspension units based on the calculated rolling state of the vehicle so as to suppress the rolling thereof. The control unit serves to determine the period or frequency of change or reversal of the direction of the detected transverse acceleration of the vehicle, and control the suspension units so as to stop the roll-suppression control when the frequency of reversal exceeds a prescribed level. The control unit further performs the first roll-suppression control operation and stop subsequent roll-suppression control operations from the instant when the frequency of reversal of the direction of the transverse acceleration exceeds the prescribed level.

摘要： Disclosed is a suspension control apparatus for a vehicle having a plurality of suspension units each disposed between a road wheel and the body of a vehicle for effectively and quickly correcting any deviation of the vehicle height from a normal height level immediately upon finishing of active suspension control operations. Priority is determined for vehicle-height control and various active suspension control operations such as roll control, nose-dive and squat control, and pitching and bouncing control so that normal vehicle-height control is stopped or inhibited during active suspension control operations are being carried out, thereby preventing the traveling attitude of the vehicle from being made unstable. Also, a vehicle-height control determining time interval from the instant when active suspension control operations has been finished until the time when vehicle-height control is restarted is substantially reduced as compared with that required in the case when the vehicle is traveling in a normal attitude without any active suspension control operation, whereby any deviation of the vehicle height from a target height level can be quickly removed to make the actual vehicle height match with a target height level in a very short time immediately after the finishing of the active suspension control operations.

摘要： An automatic tilting vehicle comprises left and right front wheels and a rear wheel. A control unit controls a vehicle tilting device so that the tilt angle of the vehicle becomes the target tilt angle. The control device is configured to swingingly vibrates the vehicle in the lateral direction by tilting the vehicle by the vehicle tilting device, to estimate a height of the center of gravity of the vehicle based on a resonance period of swinging vibration of the vehicle, and to correct the target tilt angle such that a perpendicular passing through the estimated center of gravity passes within a range of a triangle formed by connecting grounding points of the left and right front wheels and a grounding point of the rear wheel.
