  • Patent number: 7676167
    Abstract: An apparatus for forming an image according to the present invention includes a coverage rate finder, a developing unit, and a control unit. The coverage rate finder finds the coverage rate of the image. The developing unit holds developer in it and includes a stirring means for stirring the held developer at a stirring speed. The developing unit supplies the stirred developer to a surface of an image carrier. When the apparatus forms the image consecutively on sheets of paper, the control unit changes the stirring speed in proportion to the coverage rate. When the apparatus forms an image with a higher coverage rate consecutively on sheets of paper, the control unit makes the stirring speed higher.

  • Patent number: 5841366
    Abstract: A traveling-path temporary-setting unit 21 sets a plurality of temporary traveling paths with different curvatures, and a calculation unit 22 calculates distances between the temporary traveling paths and preceding vehicles detected by a radar unit 1. In case of a properly-set temporary traveling path, the path and running loci of the preceding vehicles are on a concentric circle. In this case, the preceding vehicles are running along this temporary traveling path, and a time change amount of calculated distances is approximately "0". A traveling-path determination unit 23 determines, one temporary traveling path having the minimum time change amount in the distances, as a traveling path of the vehicle.

  • Patent number: 5680097
    Abstract: When information of an obstacle is not outputted from a radar device, a presumption device presumes at least a present value of a distance between a vehicle and the obstacle based on information in a memory part obtained until the time, and a contact-possibility judgment device judges a possibility of contact of the vehicle with the obstacle based on the information from the presumption device. A detection device is provided for detecting conditions at the time when the information of the obstacle is not outputted from the radar device, for example, a relation of relative position of the obstacle to the vehicle. Further, a restriction device is provided for restricting the presumption by the presumption device according to the relation of relative position. Thus, a possibility of contact of the vehicle with the obstacle running forward of the vehicle is appropriately judged and mis-operations of an alarm, an automatic braking and the like are prevented, while ensuring running safety.

  • Patent number: 5598337
    Abstract: A suspension control system for feedback-controlling the sprung mass acceleration signal y.sub.m and a method for introducing the unsprung mass acceleration signal y.sub.L into a tuning circuit to tune gain of an FIR filter. In this system, tuning is performed so as to cancel the road surface input y.sub.m close to a reference frequency (around 10-12 Hz). As a result, the sprung mass acts as a dynamic damper upon the road surface input y.sub.m close to the reference frequency (around 10-12 Hz), however, frequency bands other than the reference frequency band do not receive the contribution of the second term in the equation (6). That is, output from the tuning circuit to an adder becomes almost zero, and normal sky-hook control is performed. Though the sprung mass system acts as a dynamic damper, the unsprung mass system exceeds the sprung mass system in mass, and excessive resonance does not occur.

  • Patent number: 5585798
    Abstract: An obstacle detection system for an automotive vehicle detects obstacles ahead of the vehicle and finds the dynamic relativity between the vehicle and each of the obstacles. Based on the dynamic relativity, information relating to a danger level between the vehicle and each obstacle is operated on so as to make a danger judgement. A frequency, at which the operations on the information relating to danger level are made, is increasingly or decreasingly varied according to the danger levels of the obstacles.

  • Patent number: 5574644
    Abstract: An automatic brake control system produces a warning before automatically making the braking action of a driving vehicle according to the velocities of the driving vehicle and the vehicle ahead. The system calculates the desired vehicle distance according to the velocities of the driving vehicle and the vehicle ahead, and sets a warning distance which is longer than the desired vehicle distance. The warning distance is set in accordance with the driver's feeling. According to the present invention, the system is prevented from producing undesirable warning.

  • Patent number: 5540298
    Abstract: An integrated controller for a vehicle comprises a contact preventive device for detecting a distance between a vehicle and an obstacle and a relative speed, and deciding whether the vehicle may come in contact with the obstacle based on the results of detection so as to perform automatic braking or automatic steering, and a characteristic changing device for causing the suspension or steering characteristic of the vehicle to be changed. The control part of the characteristic changing device changes the suspension or steering characteristic based on information from the control part of the contact preventive device when operating the contact preventive device. In case the characteristic changing device is an active suspension device, the control part changes the suspension characteristic so as to increase a control gain when performing automatic braking and to inhibit the vehicle from being rolled when performing automatic steering.

  • Patent number: 5530651
    Abstract: The vehicle is provided with a radar unit for detecting an obstacle existing ahead in the course of the running way along which the vehicle is running. When the radar unit detects a variation in its detectable region, such as a detectable distance or a detectable area range in left and right directions, from the detectable region to be detectable during ordinary running, a safety unit such as an alarm unit or an automatic brake unit is operated. A control logic for operating a collision-avoiding system for avoiding a collision with the obstacle existing ahead, such as an alarm unit or an automatic brake unit, is altered to a safe side on which safety in driving the vehicle is improved, when the detectable region is varied.

  • Patent number: 5495254
    Abstract: A method to determine a horizontal error of a radar device mounted on a vehicle along with the mounting error or imbalance in the diameters of wheels based on an echo signal from a reflector provided on a road. A vehicle's traveling locus is stored in advance as a reference locus obtained from the distance L between the vehicle and reflector and the direction .theta..sub.R. A traveling locus when the vehicle is actually traveling in a straight line where the steering handle is kept in a neutral position is compared with the previously stored reference locus. A horizontal error is obtained from the traveling locus on the coordinate axis .theta..sub.R and the shift from the reference locus.

  • Patent number: 5483453
    Abstract: When the vehicle has deviated or is deviating from a lane on which the vehicle has been or is running, the deviation of the vehicle from the lane can be suppressed, for example, by allowing the steering wheel to be operatively rotated prior to an intention of the operator. The timing of suppressing the deviation of the vehicle can be altered in accordance with conditions including, for example, the existence of a lane in the direction of deviation of the vehicle on which another vehicle is running in the same direction, the existence of an obstacle in the direction of deviation of the vehicle, the existence of an adjacent lane in the direction of deviation of the vehicle on which another vehicle is running in the opposite direction, a state of the lane on which the vehicle is running, such as a curved lane or a straight lane, a direction of deviation is outside or inside the curved lane or a lane width, a vehicle speed, a steering angle of a steering wheel, an extent of vision, and so on.
