摘要： PURPOSE:To enable comfort in driving to be improved when a car runs on an extremely rough road accidentally by controlling a suspension device in such a manner that a rear wheel suspension characteristic is changed when a front wheel has passed over the extremely rough road accidentally, then the characteristic is returned to the original condition after the rear wheel has cleared the above said rough road. CONSTITUTION:In a configuration where a suspension (c), the characteristic of which is changeable, is arranged between a body (a) and a rear wheel (b), a front and a rear wheel ground clearance detecting means (e) and (g) are arranged between the body (a) and the wheels at the front (d) and the rear (b) as the ground clearance. In addition, No.1 and No.2 decision means (f) and (h) are arranged so as to decide whether or not the detected ground clearance data are out of the stated range. When the ground clearance is decided to be out of the stated range by No.1 decision means (f), the suspension characteristic of the rear wheel is changed. Furthermore, a rear wheel suspension characteristic change means (i) is arranged so that the changed characteristic is returned to the original one, when the ground clearance is decided to be out of the stated range by No.2 decision means.

摘要： PURPOSE:To ensure the diagnosis of a vehicle, by storing, in a memory, a group of data consisting of the speed and travel distance of the vehicle and the identification of wheels when a control and computing circuit is energized to deliver a signal for operating an actuator. CONSTITUTION:A back-up memory 41 is stored therein with information concerning the speed of a vehicle upon starting, information concerning a travel distance after control and information concerning the identification of control hydraulic systems together with information of diagnosis. A control and computing circuit 3 indicates the thus stored information on an indicating lamp 57 which therefore flushes. Of the thus flushing waveforms, a first group of information indicates the travel distance subsequent to the initiation of control while a second group of information indicates the vehicle speed subsequent to the initiation of control, and a third group indicates the identification of hydraulic systems to be controlled. Further, in accordance with the instructions from a CPU in the control and computing circuit 3, a control and computing monitor circuit 7 observes the control and computing circuit 7 while wire breakage detecting circuit 22 detects sensors 11 through 13, and an output monitor circuit 55 observes the operation of an actuator 53. The above-mentioned information is used as a reference for trouble shooting.

摘要： PURPOSE:To stop a pulse motor correctly at any optional rotating angle and allow multi-step switching by driving to open or close, via a pulse motor, a valve device determining the flow opening through fluid chambers partitioned by the piston of a shock absorber. CONSTITUTION:A piston 10 partitioning an oil reservoir chamber into two is inserted in the lower structure of a shock absorber, the opening of the first rotary valve housed in the piston 10 is controlled by a control rod 12 penetrating a piston rod 11. A valve operating chamber 15 communicated to an upper structure via the second rotary valve 17 and a sub-air chamber 16 are also provided. Accordingly, the first rotary valve is operated by a pulse motor driven and controlled in response to the difference between the target opening and the actual opening, and in this case, the actual opening data are counted up (or counted down) for every positive (reverse) step of the pulse motor 1 to update the flow opening data.

摘要： PURPOSE:To maintain a constant speed of a vehicle, by adjusting a gear position and a throttle valve in accordance with a specified speed of a vehicle. CONSTITUTION:In case when a load put on an engine of a vehicle is increased when going up a slope, etc., a speed of the vehicle becomes slower than a specified speed of the vehicle, and the duty ratio of an output signal from a comparing circuit 20 becomes large. An actuator 28 is controlled by this signal, but when the speed of the vehicle is further decreased, an output of a comparing circuit 51 becomes on, a transistor 62 is turned on, a solenoid 66 is made a non- conducting state, and the gear is shifted down to No.3-speed from No.4-speed. As a result, the vehicle maintains a constant speed since decrease of the vehicle speed is compensated by increase of tractive force.

When brake is not applied, a correction coefficient calculating means V calculates the correction coefficient for correcting the deviation of the wheel speed as the correction object from a specific wheel speed as standard out of a plurality of calculated wheel speeds, on the basis of the signal supplied from the car speed sonsor I . A correction calculating means VI performs multiplication between the calculated correction coefficient and the wheel speed as correction object, and the wheel speed is corrected. An electronic control circuit IV outputs a control signal into a brake hydraulic pressure control signal III on the basis of the corrected wheel speed.

摘要： PURPOSE:To prevent the excessive reduction of a brake pressure during high mu level traveling by judging the mu level of a frictional coefficient and controlling the decompression gradient so as to be gentle for a certain period after decompression, during the time when the high mu level is judged. CONSTITUTION:The wheel speed signal supplied from a car speed sensor (b) is input into a control circuit (c). The mu level judging means (d) of the control circuit (c) estimates the frictional coefficient mu between a tire and a road on the basis of the above-described signal. When the mu level is judged high, the decompression gradient switching means (e) in the control circuit (c) outputs the instruction signal for obtaining the gentle decompression gradient at least for a certain period after the star of decompression, into a brake hydraulic pressure adjusting member (a) during the time when the high mu level is judged and controls the adjusting member (a) for the brake hydraulic pressure.

摘要： PURPOSE:To reduce the number of mechanical elements of solenoid valves by selectively connecting a wheel brake to the high pressure/low pressure of a brake pressure source by a selector valve means and executing the gently decompression, holding, and gentle pressure increase by a brake pressure control means. CONSTITUTION:By the operation of an ECU 10, wheel brakes 6-9 are selectively connected with the high pressure 18, 18A or low pressure 20, 20A of a brake pressure source 2 by the selector valve means 3, 3A, and 4, 4A according to the presence in an antiskid brake pressure control start region or not. In this case, the brake pressure control means of the ECU 10 supplies the pressure corresponding to the gently reduced pressure, holding state, and the gently increased pressure into wheel brakes 6-9 in the repetitive duty of the OFF (high pressure)/ON (low pressure) of the selector valve means 3, 3A, and 4, 4A. Thus, the necessary quantity of the selector valves can be reduced, for example, from eight in the prior art to four, and the exclusively used space of the valve device can be economized.

摘要： PURPOSE:To achieve a higher accuracy with a higher noise compression effect, by arithmetically averaging the number of pulses and a section time separately to determine a speed or an acceleration of a vehicle rotating section from an average number of pulses and an average section time. CONSTITUTION:An antiskid brake system is made up of an object 10 desired to detect rotation provided on a wheel, a magnetic sensor 12 as opposed to the object 10, a speed/acceleration detector 14 for detecting a speed and acceleration of the wheel from an output of the sensor 12 and a brake controller 18 for controlling a brake oil pressure to a brake cylinder 16 from the speed and acceleration thus detected. The speed/acceleration detector 14 has a speed pulse generation circuit 20, a measuring circuit 22 for the number of speed pulses and a section time and a speed/acceleration computing circuit 24. Then, the number of speed pulses and the section time are arithmetically averaged separately to determine the speed and acceleration from the average number of pulses and the average section time.
