摘要:
An automatic speed control apparatus for controlling the running speed of a vehicle at a constant set speed includes an auxiliary intake passage providing direct communication between portions of a main intake passage upstream and downstream from a throttle valve so as to bypass the throttle valve, an auxiliary intake air valve adapted for controlling the flow rate of air in the auxiliary intake passage, and a fuel supply cut-off means for suspending the supply of fuel to the engine from a moment at which a fuel supply cut-off condition is met, which requires the throttle valve to be set at the minimum opening position and the engine speed to be higher than a predetermined fuel supply cut-off engine speed, until the moment at which a predetermined fuel supply recovery condition is met. An actuator for actuating the throttle valve is controlled so as to vary the degree of opening degree of the throttle valve and enable the vehicle to run at the constant set speed. The auxiliary intake air valve is controlled in such a manner that the flow rate of air in the auxiliary intake passage is reduced before the fuel supply cut-off condition is met during motion of the vehicle under the control of the automatic driving apparatus. The rate of fuel supply to the engine has therefore been reduced before the fuel supply is actually cut-off so that the amount of change in the engine output torque and, hence, the level of shock produced by the change in the engine output torque are reduced when cut-off of the fuel supply is executed.

A constant speed cruise control system of duty ratio control type for approximating an actual car speed to a stored target car speed, by on/off control of a control valve of an actuator to adjust the throttle valve opening degree by an output duty ratio D obtained from a control line having a gradient showing a conversion characteristic of car speed and duty ratio.The system has a controller in whicha set duty ratio DS corresponding to the target car speed is calculated asSD=SD1+(DM-SD1)/nand the output duty ratio D is calculated asD=G.times.V+SDwhereG: gradient of control lineV: car speed deviationDM: integrating element responding quickly to duty ratio changeSD1: integrating element responding slowly to duty ratio changen: coefficientand the controller corrects to integrate the set duty ratio SD in a direction of approximating the output duty ratio D.
摘要:
A constant-speed control device for a vehicle including a fuel cut device and a suspending device which suspends a fuel cut operation. An actuator is provided for controlling a throttle valve so that the vehicle runs at a constant speed. The fuel cut device carries out a fuel cut when the degree of opening of the throttle valve is smaller than a predetermined value. The suspending device suspends operation of the fuel cut device until the vehicle speed becomes higher than a target value by a predetermined value.

A collision absorption system including a collapsing armrest. The armrest is configured to provide support for vertical loading during use. During a side impact collision, the armrest is configured to deform or collapse in a lateral direction. The collapsing armrest may include multiple layers with at least one layer having grooves and channels, or containing cross-ribs, to allow greater deflection in a lateral direction during a side impact collision.

According to one embodiment, there is provided an electric-vehicle driving apparatus which consumes regenerative energy by a brake resistor and can decrease harmonic components generated by a brake-chopper switching circuit. Plural brake-chopper switching circuits are provided in parallel for each inverter. Harmonic components generated by the brake-chopper switching circuits are decreased by changing phases or frequencies of triangular carrier waves of the switching circuits, relatively to each other.

Provided is a shrinkable label having a hologram layer that suffers no whitening even after shrink processing with relatively large shrinkage. The label therefore fits even complicated dimensions of an article and, in addition, provides a superior holographic expression.The shrinkable label includes a shrinkable film and a hologram layer present on or above at least one side of the shrinkable film. The hologram layer has been formed by curing a radically curable resin composition by the action of an active energy ray. The resin composition contains 45 to 95 percent by weight of an acrylic monomer and 5 to 55 percent by weight of a bifunctional or higher-functional urethane acrylate, based on the total amount of the acrylic monomer and the bifunctional or higher-functional urethane acrylate.

An apparatus for detecting a position of a wheel tilting angle adjustment member, which can detect the position of the wheel tilting angle adjustment member in accordance with irregularity in a position of the wheel tilting angle adjustment member caused by the irregularity in an entry position of each vehicle or difference in a relative position of the wheel tilting angle adjustment member with respect to the wheel of each vehicle type without visual observation by an operator, is to be provided. A horizontal direction position of the table 3 is detected by table position detection means 5a and 5b while a wheel 2 mounted on a vehicle W is seated on a table 3 which is freely floated in an arbitrarily horizontal direction, and the position of a wheel tilting angle adjustment member A coupled to the wheel 2 is calculated on the basis of the detection result and relative position information on the wheel tilting angle adjustment member A with respect to the wheel 2, which is stored in storage means ROM.
