An electric power-steering device has a speed-reducing mechanism (17) for reducing the speed of an output shaft (16) of an electric motor (15). The speed-reducing mechanism (17) has an internal gear (39) engaged and rotated with the output shaft (16) and an external gear (40) with which the internal gear (39) internally meshes. A drive pulley (41) rotatable together with the external gear (40) and a driven pulley (42) provided so as to surround a steering shaft are connected by an endless belt (43). Speed reduction is obtained by the internal gear (39) and the external gear (40), and the speed-reducing mechanism (17) as a whole achieves a high reduction ratio without greatly reducing the diameter of the drive pulley (41).

A declaration control apparatus and method for a vehicle, which performs deceleration control such that a deceleration acting on the vehicle becomes equal to a target deceleration by an operation of a brake system which applies a braking force to the vehicle and a shift operation which shifts a transmission of the vehicle into a relatively low speed or speed ratio, increases the target deceleration over time at a predetermined gradient to a predetermined value when a determination that there is a need to shift the transmission into a relatively low speed or speed ratio has been made, and after the target deceleration reaches the predetermined value, maintains the target deceleration at a generally constant value. As a result, a deceleration transitional characteristic of the vehicle is able to be improved.

A driving/braking force manipulation control input of a k-th wheel, which denotes one or more specific wheels among a plurality of wheels of a vehicle, is determined such that a required condition concerning a relationship among a road surface reaction force that may act from a road surface on the k-th wheel on the basis of the detected values or estimated values of a side slip angle and a friction characteristic of the k-th wheel, a feedback control input related to the driving/braking force of the k-th wheel for bringing a difference between a state amount of the vehicle and a reference state amount close to zero, a driving/braking force feedforward control input based on a drive manipulated variable supplied by a driver of the vehicle, and a k-th wheel driving/braking force manipulation control input is satisfied. This arrangement makes it possible to properly control a motion of an actual vehicle to a desired motion while properly considering the characteristics of a road surface reaction force acting from a road surface on a wheel.

PURPOSE: To regulate braking force in response to a change in engine brake characteristics, so as to improve accuracy in automatic braking control by judging the necessity of braking of a vehicle by a braking device by means of the of an operating condition detecting means, calculating a target braking value, and correcting the braking force according to a detected engine brake force. CONSTITUTION: Target deceleration being a target braking value is calculated according to an inter-vehicle distance, vehicle speed, relative speed and longitudinal G detected by the radar head parts 33 and 34 and a longitudinal G sensor 43 as an operating condition detecting means, and reference brake pressure is set according to a detected shift position, and brake pressure is controlled in a feedback process so as to be converged to the target deceleration by using the reference brake pressure as a reference. Anticipative judgment is made on whether or not deceleration fuel cut is released by an EG160, and when it is judged that release is carried out, the brake pressure is increased temporarily by an automatic braking control unit 45.

Automatic braking device for vehicle

PURPOSE: To provide an automatic automobile brake control device capable of improving the rotational efficiency of a vehicle correspondingly to steering operation only in the necessary case while maintaining the braking property of the vehicle. CONSTITUTION: When driver's steering operation is detected in the automatic automobile brake control device for detecting a distance between a self-vehicle and an obstacle and a relative speed, judging the possibility of contact between the vehicle and the obstacle, and at the time of judging the possibility of contact, automatically acting braking pressure on respective wheels to brake the vehicle, the braking pressure is controlled at every wheel so as to improve the rotational property of the vehicle in the operation direction and the control of braking pressure at every wheel is executed only when operator's steering operation is detected, the self-vehicle and the obstacle are in an approaching state and the device judges to the effect that contact between the self-vehicle and the obstacle can not be evaded only by the braking operation of the vehicle based upon the control of braking pressure.

PURPOSE:To provide an automatic brake controller for a vehicle which can obtain the constant brake characteristic even if the supplied voltage to a solenoid valve lowers and provide an electricity supply controller for an automobile which can suppress the lowering of the supplied voltage to the solenoid valve. CONSTITUTION:As for an automatic brake controller for a vehicle which is constituted so that the desired brake characteristic is obtained by adjusting the brake pressure by duty-controlling the solenoid valves 11, 12 and 13 installed in a brake pressure control circuit, the voltage of an on-vehicle battery B is detected by a voltage monitoring part 62, and a control part 60 which suspends the duty control when the battery voltage is less than a prescribed value, and fixes the control position of the solenoid valve at the position corresponding to the prescribed brake pressure is provided. Further, as for an electricity supply controller for an automobile which is equipped with an automatic brake controller for a vehicle, the electric power supply quantity to the electric part which does not contribute to the traveling of the vehicle is reduced during the operation of the automatic brake controller.

When the judgment is Yes, it is judged that collision of a vehicle is caused, and an air bag device is actuated. COPYRIGHT: (C)1996,JPO

Overall control device of vehicle

PURPOSE:To achieve fault diagnosis without giving sense of instability to a driver by providing a changing means for changing the condition of fault judgment from a fault judgment means in the direction where the result of fault judgment is output soon, for a specific period of time, to carry out diagnosis for a point of fault memorized in a memory means at the time of starting operation of a controller after an engine is re-started. CONSTITUTION:When fault judgment is carried out by a fault judgment means 32, a sensor, for which fault is judged is recognized and memorized by a memory means 34, and the memory is retained until a controller is started to be activated after an engine is re-started. The condition of fault judgment is changed in the direction where the result of fault judgment is output soon, by a fault judgment means 32, for a specific period of time, to carry out diagnosis for a fault sensor stored in the memory of the memory means 34, by a judgment condition changing means 35, at the time of activation of the controller after the engine is re-started. It is diagnosed fast and accurately whether the fault judgment is caused by true fault of the controller by judging fault in the condition different from the fault judgment at the time of re-starting the engine.
