摘要:
The invention relates to circuits which increase the reliability of a passenger restraint system. In one embodiment, the connection layout with respect to a main power source, such as a vehicle battery, prevents accidental activation in the event certain portions of the wiring become grounded and which enables the activation when required even when some of the wiring is cut. Another embodiment increases the time for a which a diagnostic system can be maintained operative should the connection with the vehicle battery be lost. A third and more complex embodiment features circuits which can estimate the amount of damage which has occurred to the vehicle and predict the displacement of person under the influence of the acceleration (deceleration) caused by a collision.

The present invention has an object to provide a vehicle control device which does not require a complicated operation to start an engine even if an idle-stop function has been executed. Thus, the present invention includes a mechanical automatic transmission, an idle-stop device (1) for stopping the engine when the vehicle is stopped, a slope detection device (2) for detecting a slope of a road, and a control unit (10), and is characterized in that the control unit (10) has a function for disengaging a clutch and selecting a gear appropriate for the detected slope, when the slope detected by the slope detection device (2) is at or above a threshold value and an operation of the idle-stop device (1) has been requested.

An object is to provide a vehicle start-up control, mechanism capable of preventing the occurrence of clutch judder with no need of paying excessive attention thereto for a driver. For this purpose, the present invention is provided with a clutch judder detection device (1) for. detecting the occurrence of clutch judder, a clutch state detection, device (3) for detecting a partially engaged clutch state, and a control unit, (10), wherein the control unit (10) has a function, for storing an accelerator opening (position) in the partially engaged clutch state in a case where the clutch judder has occurred during start-up and a function, for comparing an accelerator opening during next start-up with an accelerator opening in case where the clutch judder has occurred during previous start-up.

A passenger protecting apparatus for inflating an air bag or tightening a seat belt is provided that is smaller in size and more reliable than any previously known passenger protecting apparatus. The passenger protecting apparatus has two switches connected in series with a squib. The switches are controlled by a control unit using independent program routines in a redundant manner. The control unit combines front collision and side collision detection in one unit. The control unit controls the switches based on the outputs of several acceleration sensors, by comparing their respective outputs to threshold values.

A control circuit for an air-bag mounted in a motor vehicle comprises an acceleration sensor for producing an acceleration signal indicative of acceleration of the vehicle, an ignition timing circuit for processing the acceleration signal to predict the time when a passenger's head will reach a front surface of the air-bag in fully deployed condition and producing a first air-bag deploying signal in accordance with the predicted time, and a damage discrimination circuit for processing the acceleration signal and judging the need of activation of the air-bag when the cumulative effect of the acceleration exceeds a predetermined limit. The damage discrimination circuit produces a second air-bag deploying signal when judging the need of activation of the air-bag. A so-called AND circuit is further employed which actually activates the air-bag when receiving the first and second air-bag deploying signals concurrently.
