Abstract: A vehicle operation control apparatus for controlling a running state of a vehicle based on a relative positional relationship between the vehicle and a preceding vehicle running in a predetermined area ahead of the vehicle. The vehicle operation control apparatus comprises a controller that determines a target deceleration of the vehicle based on the relative positional relationship between the vehicle and the preceding vehicle. The controller controls a deceleration of the vehicle so that the deceleration of the vehicle approaches the target deceleration and maintains the target deceleration until a predetermined condition is satisfied.

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.

Abstract: Stereo image data depicting the lane on which the vehicle is running is rectified into a planar image on which one or more level lines can be generated in a manner to intersect one or both of the edges of the lane. Angles are measured between lines which extend from these the points if intersection in directions normal to the level line or lines and lines which extend tangentially to any curvature which occurs in the road edges at the point of intersection. These angles are recorded, the difference therebetween determined and compared in a manner which determines the attitude of the vehicle on the road. The curvature of the road and the vehicle speed are determined and the best steering angle for the road wheels determined in accordance With a schedule which is recorded in terms of attitude and a parameter variable with the vehicle speed and road curvature.

Abstract: An autonomously running vehicle and method for autonomously running the vehicle on a route of travel are disclosed in which using a plurality of control rules defining predetermined steering controlled variables according to magnitude classifications of previously classified deviations on steering operations and membership functions indicating certainties corresponding to respective classifications of actual deviations (offset), the certainties corresponding to each magnitude classification are correlated to the control rules to determine the steering controlled variable. In the autonomously running vehicle, the vehicle's running scenes are automatically detected on the basis of the image data derived by an image processing unit. Reference membership functions are varied (constricted or reduced) according to any one of the running scenes so that the membership functions are automatically set according to the running scenes. Control rules are previously set only to the reference membership functions.

Abstract: An autonomous vehicle controls the steering of the vehicle on a road by fuzzy control. A camera forms an image of the road, and an image processor processes the image to calculate the deviation dx between a plurality of reference points on a road and the direction in which the vehicle is traveling. Each reference point is associated with a visual point on the road ahead of the vehicle. The product of the deviation dx for each visual point and a membership function .mu. indicating the degree of importance attached to the visual point is calculated, and a total deviation equal to the sum of the products is calculated. The steering of the vehicle is controlled on the basis of the total deviation. The membership functions .mu. are varied in accordance with the time rate of change of the deviations dx.

Abstract: An image processing section receives data from cameras mounted on the vehicle and produces an image or images from which a first set of so called "local" data is derived and compiled. A sensor section senses the rotational characteristics of two vehicle wheels and the conditions prevailing on either side of the vehicle and complies a second set of so called "global" data. The local and global data are compared and data is only accepted in the event that the differences between the two sets of data fall within predetermined limits and data which falls outside of the ranges deemed erroneous and rejected.

Abstract: The present invention relates to an access request control apparatus and more specifically to an apparatus for determining priority between a plurality of access requests in a memory control apparatus which uses a pipeline. One of the access requests from a plurality of channel processing devices CHP's is selected by a first priority determination circuit. The selected CHP request, the requests from a plurality of central processing units and the request in the loop-back of the pipeline control circuit are considered for selection by a second priority determination circuit. In case a CHP request, selected by the first priority determination circuit, is not selected by the second priority determination circuit or selected but nullified in the course of the pipeline, the CHP request is returned to the first priority determination circuit. But, in this case, a higher priority is given to the CHP request in the first priority determination circuit.

In particular, in a storage system where the buffer storage BS and main storage MS are provided, access is first made to BS based on and access request and if the desired data is not found in BS, access is made to MS. When the desired data is not found in BS and access is then made to MS, acces to BS is carried out based on the next access request from the same access requesting unit in parallel with the access to MS by the first access request.

Abstract: The present invention discloses a data processing system having a program structure and execution mode where an actual argument is bound to a formal argument of a function to be called by storing a pair of a variable name as the formal argument and a variable as the actual argument into a First-In-Last-Out type stack memory which is an environment list, the function called executes processings using a latest bind value of said environment list when referring to variable values, when a value of such function is obtained, the function value is returned by deleting the formal argument variable of the function from the environment list. The system includes an associative buffer memory provided externally to the stack memory, where at least the variable name and location data of variable on the environment list are stored in the associative buffer memory, and thereby the access time for referring to variables stored in the stack memory can be curtailed.
