    摘要: An obstacle sensing apparatus for vehicles is provided in which detection of obstacles is performed efficiently by predicting the traveling path of the vehicle appropriately when detection of obstacles by a radar unit is limited to a region along the traveling path. The apparatus is provided with a radar unit for transmitting radar waves ahead of the vehicle and sensing obstacles present ahead of the vehicle, a steering angle sensor for sensing the steering angle of the vehicle, and a yaw rate sensor for sensing the yaw rate produced by the vehicle. First traveling-path predicting device predicts a traveling path of the vehicle based upon the steering angle, and second traveling-path predicting device predicts a traveling path of the vehicle based upon the yaw rate. One of these traveling paths is selected in dependence upon the operating state of the vehicle and detection of articles by the radar unit is carried out within a limited region along the traveling path selected.

    摘要: 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.

    摘要: Disposed between a sprung element and an unsprung element is a shock absorber of multi-degree variable-damping-coefficient type. A damping coefficient of the shock absorber is changed so that an actual damping force generated by the shock absorber becomes equal to a target damping force that causes no sprung vertical motion. Such a change is inhibited when the difference between the damping force and the target force falls in the range of a predetermined value. The value is changed according to the magnitude of an damping coefficient now in selection of the shock absorber. This allows the shock absorber to effectively produce damping forces while at the same time preventing the damping coefficient from being changed too often to avoid the occurrence of chattering. Additionally, control delay due to the presence of a dead band zone is lessened. Traveling stabilization and riding comfort is improved.

    摘要: Periodic first vibrations generated from the engine are reduced by the interference with the second vibrations generated from the speakers disposed in the vehicle compartment of the vehicle. The second vibrations are set in a cycle unit of the first vibrations, and they are corrected (optimized) on the basis of the signals from the microphones detecting the vibrations within the vehicle compartment and the transmission characteristic between the microphones and the speakers. During a transient period of time during which the cycles vary (during which the data lengths of the data of the second vibrations vary), such as by acceleration or deceleration, the data on the vibration wave form of the previous vibrations is corrected in anticipation (i.e. the data length is corrected), the current vibration wave form is set. The correction of the data length is made by inserting a given number of estimated data values into the previous data length or by deleting a given number of the data values from the previous data length. Further, the data length can be corrected by extending or contracting the previous vibration wave form as a whole so as to provide the data length in accordance with the current vibration wave form.

    摘要: 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.

    摘要: A suspension system for a vehicle has shock absorbers, each provided so as to be associated with one wheel and between sprung parts and unsprung parts, step motors, each being adapted for changing damping force characteristics of one of the shock absorbers by open loop control, and a controller for outputting control signals to the step motors. The controller is adapted for outputting control signals every predetermined time interval so as to make the damping force characteristics of the shock absorbers harder. According to the thus constituted suspension system for a vehicle, it is possible to prevent the driving stability from being lowered even when at least one of the step motors is thrown out of synchronism.
