摘要:
Information storage element 102 and transmitter-receiver 103 are molded in resin connector part 101 of fuel injection valve 100 which projects outside of the engine by molding. The precise control of an injection amount is enabled by using directly the characteristic of injection amount stored in information storage element 102, and obtaining the width of the injection command pulse corresponding to the injection amount instruction value. Thereby, the minimum injection amount which is the minimum value of the fuel supply amount which can be controlled is reduced.

In a radio wave radar system using a two-frequency CW modulation method, it is possible to detect a distance between a host vehicle and a forward vehicle and to realize a stable ACC following travel, even in a condition in which the relative speed is 0. By combining the two-frequency CW modulation method with the frequency pulse CW modulation method, that is, by using combination with the two-frequency CW method when the relative speed occurs and the frequency pulse CW method when the relative speed is close to 0, even if the relative speed is 0, the IF signal obtained from the reflected wave from the forward vehicle can be generated to detect the existence of the ACC target vehicle, so that it is possible to realize a stable ACC following travel.

An intelligent cruise control system is capable of maintaining a car-to-car distance allowing a collision to be avoided and carrying out follow-up running control without providing a sense of incompatibility to the driver. A radar circuit employed in a radar unit calculates a relative speed Vr of a car running ahead of a vehicle with an intelligent cruise control system installed therein with respect to the vehicle and a distance dr from the vehicle to the preceding car from a wave reflected by the preceding car. An ICC unit adjusts the speed of the vehicle by controlling the output of the engine of the vehicle in accordance with information such as the relative speed Vr and the distance dr received from the radar unit. In a follow-up running mode, the ICC unit controls the cruise of the vehicle in such a way that the speed of the vehicle and the distance from the vehicle to the preceding car are maintained at a target speed and a target car-to-car distance respectively. When the ICC unit forms a judgment that deceleration of the vehicle is not enough if only deceleration based on the engine brake is relied on, giving rise to fear of a rear-end collision of the vehicle with the preceding car, the ICC unit calculates a target deceleration and operates an automatic brake unit, letting the automatic brake unit generate a braking force appropriate for the target acceleration.

A ATM communication system can satisfy various requests from a node system, a link system, and the like, by performing a self-format transform between a format to be transmitted and a format receiving an ATM switch, and using a cell processing function for performing polishing/shaping, counting of passed cells, counting of discarded cells, drop/insertion of OAM cell, and the like.

In order to consider an optimum control method and an optimum mounting method needed, a UWB having a communication function and a radar function are used. For an obstacle vehicle in front, the distance between two cars is measured using the radar function, and according to this distance, a hazard warning is issued to a driver or a pre-crash operation is carried out. Moreover, by informing its own position to each other between vehicles using the communication function, the distance to a vehicle near to the own vehicle is measured regardless of clutter, and according to this distance, a hazard warning is issued to a driver or a pre-crash operation is carried out. Moreover, the operating frequency and transmission power of a radar are changed based on its own location information, thereby reducing influence to and from other wireless system.

Telephones are coupled with data terminal equipments through data lines. The data lines are used to transfer the terminal data between the data terminal equipments and the telephones. Speech signals are transferred between the telephones and a PCM telephone exchange through speech lines. Control lines are used for transferring a time-division-multiplexed signal made of telephone control signals such as lamp energizing signals, and the terminal data, and also used for transferring another time-division-multiplexed signal made of function signals such as function key actuation signals and the terminal data. With such a connection, a speech signal is transferred between telephones through the PCM telephone exchange and speech lines and the terminal data are transferred through the control lines and the PCM telephone exchange.
摘要:
A cruise control device and an obstacle detection device are provided which achieve a safe and appropriate tracking control by avoiding a sudden recognition of a short following distance when a preceding vehicle is found in an uphill or downhill gradient, in a curve, or at an intersection, or by reducing the damage of a crash when the crash cannot be avoided. An obstacle determination process section is provided which receives information from a sensor which detects an obstacle, receives terrain information of the position of the host vehicle from a navigation device, and determines the presence of the obstacle when a predetermined condition is satisfied after the sensor detects the obstacle. The predetermined condition to determine the presence of the obstacle is changed based on the terrain information of the position of the host vehicle received from the navigation device.
