摘要： A braking force increasing device composed of a pump and a control valve continuously increases brake-fluid pressure of wheel cylinders when a brake pedal is operated by a driver and a variation of driver's operation of the brake pedal is within a predetermined range. As a result, even when the driver keeps the brake pedal depression at a certain stroke substantially, braking force can be gradually increased. Therefore, it is not necessary for the driver to depress down the brake pedal more strongly to cause braking force to be applied to the vehicle.

摘要： A spatial bulletin board system for virtually writing a memo in an actual space and displaying the memo superimposed on a picked-up image of the actual space. The system includes an input device that converts drawing movement during the creation of content in an actual space to three-dimensional coordinate information and acquires positional information which specifies a place in which the memo is written and saves the information in a spatial communication server. In the image-pickup place, the picked-up image is displayed on a spatial bulletin board display device and a browsing request is sent to the spatial communication server.

摘要： An object of the present invention is to execute an optimum control of vibrations due to a driver's operation of an accelerator pedal, steering wheel and brake pedal. The operation instructions are inputted into a vibration calculating means (kinetic model) comprising a vehicle body model, suspension model and tire model. Conventional kinetic model controlled the suspension in order to suppress the vehicle body vibration. However, in the kinetic model of the present invention, the tire vibration due to a change in the engine output is first absorbed by the suspension, whereby a residual vibration which was not be absorbed yet by the suspension is transferred to the vehicle body. The operation inputs are compensated by the three feed-back loops between the outputs of the above-mentioned three portions and input of the tire portion, giving the highest priority on the vehicle body model.

摘要： In an obtainer for obtaining speed feeling of a driver of a movable object, a gaze point setter sets a gaze point of the driver, and a motion detector detects relative motion of an environmental field around the mobile object with respect to the mobile object. A divergent component calculator projects the relative motion of the environmental field in a coordinate system. The coordinate system is formed by modeling a retina sphere of the driver of the mobile object. The divergent calculator calculates each of divergent components of the projected relative motion of the environmental field radially expanding from the gaze point. A speed feeling calculator calculates speed feeling of the driver based on the divergent components of the projected relative motion of the environmental field radially expanding from the gaze point calculated by the divergent component calculator.

摘要： A method and an apparatus for estimating behaviors of a vehicle are provided. At least two GPS antennas are located along a longitudinal axis of a vehicle so that speed vectors at the positions where the GPS antennas are located can be determined based on GPS signals received by the GPS antennas. The speed vectors are known to be estimated with high accuracy based on the GPS signals. The positions of the GPS antennas on the local coordinate system are estimated based on such highly accurate speed vectors, so that the estimated positions may also have high accuracy. Based on a line connecting these highly accurate positions of the GPS antennas, an inclination of the longitudinal axis of the vehicle is estimated. Use of the high-accuracy speed vectors enables high-accuracy estimation on the positions of the GPS antennas and the vehicle direction on the local coordinate system.

摘要： A vehicle stability control system includes a base required driving force calculation unit, an estimated driving force estimation unit, and a required driving force correction unit. The base required driving force calculation unit calculates a physical quantity to generate the base required driving force at a driving wheel. The estimated driving force estimation unit estimates a driving force as being generated in the vehicle. The required driving force correction unit obtains a correction to suppress a potential pitching vibration in the vehicle. The physical quantity calculated by the base required driving force calculation unit is corrected on the basis of the correction. The corrected required driving force obtained by the required driving force correction unit is generated at the driving wheel.

摘要： A vehicle control system estimates the vibration states of tires by using a vehicle vibration model that is separated into a vehicle body vibration model, a chassis vibration model, and a tire vibration model with high precision. The tire vibration model in the vehicle vibration model is formed of a rear wheel tire vibration model, a front wheel tire vibration model, and a virtual coupling element vibration model that virtually couples the rear wheel tire vibration model and the front wheel tire vibration model. Influence of the vibration state that is conducted between the front wheel tires and the rear wheel tires is considered while the tire vibration model and the chassis vibration model are separated from each other, thereby making it possible to estimate the vibrations that occur in the front wheel tires and the rear wheel tires.

摘要： While a driving torque TD outputted to a driving shaft via an AT from an engine is detected, a road-surface transmitting torque Td_tire is detected based on rotation speeds Vwdr, Vwdl of vehicle driving wheels, a vehicle body speed Vd, and driving torques Tdr, Tdl, all of which are previously detected. The driving torque TD and the road-surface transmitting torque Td_tire are then compared to each other. When TD>Td_tire, the driving torque from an engine is controlled so as to decrease a value of (TD−Td_tire). The vibrations of individual vehicle parts are thereby decreased.
