    摘要: There is provided a delay time calculating method for use in a hierarchical design, capable of accurately calculating the delay amount at a boundary between different level layers in a hierarchical structure. A whole chain (T$01 to T$13) is divided into a first partial chain (T$04 to T$10) and a second partial chain (T$01 to T$03, T$11 to T$13). A first delay amount (TD(4-10)) of the first partial chain (T$04 to T$10) is calculated. A third partial chain (T$01 to T$05, T$09 to T$13) consisting of the second partial chain (T$01 to T$03, T$11 to T$13) and a plurality of chain elements (T$04 to T$05, T$09 to T$10) included in an end region of the first partial chain (T$04 to T$10), is generated, and a second delay amount (TD(1-5), TD(9-13)) of the third partial chain (T$01 to T$05, T$09 to T$13) is calculated. An end chain element (T$05, T$09) of the above mentioned plurality of chain elements (T$04 to T$05, T$09 to T$10) is separated from the third partial chain (T$01 to T$05, T$09 to T$13), and a third delay amount (D(5), D(9)) of the end chain element (T$05, T$09) is calculated. The third delay amount (D(5), D(9)) is subtracted from the second delay amount (TD(1-5), TD(9-13)) to obtain a fourth delay amount (TD(1-4), TD(10-13)). The fourth delay amount (TD(1-4), TD(10-13)) is overwritten to the first delay amount (TD(4-10)) in units of chain elements to calculate the delay amount (TD(1-13)) of the whole chain. Thus, an inaccurate value is canceled, so that an accurate relation between the delay amount of a partial chain and the delay amount of the whole chain can be obtained.

    摘要: A brake system for a vehicle includes a liquid pressure generating device for generating a liquid pressure dependent upon a manual operation, actuators having output ports for outputting a liquid pressure dependent upon an electrical command signal from a controller, and which are adapted to be connected to a reservoir when the actuators are non-operative, and switchover valves switchable between a state in which wheel brakes are connected to the liquid pressure generating device, and a state in which the wheel brakes are connected to the actuators. In the brake system, on-off valves are connected between the output ports of the actuators and the switchover valves, and are opened when the liquid pressures output from the actuators is equal to or higher than a predetermined value.

    摘要: A traction control device for a vehicle includes a control unit for operating wheel brakes for left and right driven wheels connected to a power source through a differential, when an excessively slipping tendency is produced in one or both of the driven wheels. In the traction control, an input torque supplied from the power source to the differential is detected by an input torque detecting device. A limit driving torque is determined based on a detection value detected by the input torque detecting device at the time when it is detected by a slip detecting device that only one of the driven wheels is fallen into the excessively slipping tendency. A braking torque to be applied to the one driven wheel is determined based on a value resulting from the subtraction of the limit driving torque from a current detection value detected by the input torque detecting device. Consequently, it is possible to reduce the control system into a relatively small size and to improve the control responsiveness and the hysteresis characteristic.

    摘要: A braking force control system of a vehicle includes a deviation reference control quantity determining device for determining an operation control quantity for the actuator on the basis of a deviation between a target deceleration determined on the basis of a quantity of operation of a brake operating member and a detected deceleration of the vehicle. In this control system, the level of operation speed is judged in accordance with whether or not the variation per unit time in quantity of operation of the brake operating member exceeds a preset value. Following two states are switched over from one to another by a switch device: a state 1) in which the operation of the actuator is controlled with an operation control quantity determined in the deviation reference control quantity determining device, when it is decided that the operation speed is slow or low, and a state 2) in which the operation of the actuator is controlled with an operation control quantity determined in an operation quantity reference quantity determining device for determining the operation control quantity on the basis of the quantity of operation of the brake operating member, when the operation speed is fast or high. Thus, the generation of an overshooting can be avoided to improve the responsiveness.
