Abstract: A curve's radius of a road on which a vehicle shall run is estimated based on actual speed, yaw rate, and steering angle of the vehicle. Accordingly, during a transition state of the vehicle, the curve's radius can be estimated with the actual yaw rate taking into account the actual steering angle that can reflect more accurately turning behavior of the vehicle than the actual yaw rate. Therefore, errors in the estimation of the curve's radius due to response delay of the actual yaw rate can be easily reduced even though the yaw rate is used for such estimation.

Abstract: A characteristics measurement device is applicable to various kinds of measurement devices for measuring characteristics subjected to a measurement in a certain environment. The characteristics measurement device measures a noise level in the environment, and determines the noise state based on the obtained noise level. Then, the characteristics measurement device determines the number of times of measurement of the characteristics based on the noise state, and executes synchronized addition of the characteristics obtained by the plural measurements to output the characteristics. Thus, when the noise state in the environment of the measurement execution is preferable, the measurement is completed in the smallest number of times of measurement. Additionally, when the noise state of the environment is not preferable, the plural measurements are executed in order to obtain the desired noise state (e.g., S/N), and the results are synchronized and added.

Abstract: A running control apparatus and method control the state of running of a vehicle based on a relative positional relationship between the vehicle and a preceeding vehicle. In a case where a brake is actuated if the deceleration deviation obtained by subtracting an actual deceleration from a target deceleration is at least a third threshold &Dgr;&agr;s3, the brake is actuated provided that an object body detected by a laser radar device is a preceeding vehicle and that the same-lane probability that the preceeding vehicle is running in the same lane as the vehicle is at least a set probability. Thus, the brake is actuated when there is a high probability that braking is needed. Therefore, erroneous operation of the brake can be reduced.

Abstract: In a vehicular braking control apparatus and method, the hydraulic pressure on a wheel cylinder is gradually reduced with a relatively gentle gradient of reduction (k3) at the time when a braking operation member, operated by an operating person of the vehicle, is detected to have been operated to a predetermined position. At the time when a state of the braking operation is detected to have reached a predetermined threshold, the hydraulic pressure on the wheel cylinder is reduced with a relatively great gradient of reduction (k2). Therefore, it is possible to reduce vibrations of a brake pedal or the change in deceleration while adopting a relatively simple construction.
