Abstract: In an automatic transmission system in which a gear transmission and a clutch are electronically controlled so as to shift the transmission to the optimum gear position, the system comprises a first generator for generating a set of initial map data corresponding to the position of a selector, the initial map data being for determining an initial target gear position to which the gear should be initially shifted after the position of the selector is changed, and a second generator for generating a set of normal map data corresponding to the position of the selector, the normal map data being for determining a normal target gear position to which the gear should be shifted after the gear is shifted to the determined initial target position. One of the outputs of the first and second generators is selected and applied to a calculator in which the target gear position is calculated in accordance with the selected map data. The gear transmission is automatically shifted to the calculated gear position.

At least an outer layer of the cylindrical portion and a cap layer closing an end opening of the cylindrical portion is fabricated from the soft synthetic resin so as to provide reliably effective annular sealing defined between the cylindrical portion of the rivet and the interior peripheral surfaces of the holes defined within panels within which the rivet is to be disposed.

Abstract: In an apparatus for controlling a vehicle with an automatic transmission which includes a gear transmission and a clutch and is responsive to the operation of a selector and an acceleration member, the selector has a special position and a low-speed running mode is allowed when the special position is selected. During the low-speed running mode, the vehicle can be driven even when the amount of operation of the acceleration member is zero level, reducing the work of the driver, especially in heavy traffic.

Abstract: An automatic transmission system having a gear transmission comprises a detector responsive to the operation of switching OFF an ignition switch for detecting whether or not the actual gear position of the gear transmission matches the position set by a selector. When the result of the detection is that the actual gear position does not match the set gear position, the gear position of the gear transmission is changed to the right position corresponding to the position of the selector at the time the ignition switch is turned off. Thus, the gear transmission is sure to be in the right gear position whenever the ignition switch has been switched OFF.

Abstract: In an apparatus for controlling an internal combustion engine for a vehicle provided with an electronically controlled automatic transmission system including a friction-type clutch and a gear-type transmission, the speed of the engine is controlled in accordance with a target speed determined by whether the clutch is engaged or not, and at the moment the clutch becomes engaged, the target engine speed gradually changes from the target speed for the disengaged condition of the clutch to that for the fully engaged condition of the clutch, whereby the mechanical shock occurring at the time of the engagement of the clutch is remarkably reduced.

Abstract: In an automatic transmission system for a vehicle having a gear-type transmission, a clutch connected to the gear-type transmission and an actuator for operating the gear-type transmission and the clutch, the system has a controller for controlling the operation of the actuator in accordance with the magnitude of load of the vehicle at each instant so as to shift the gear-type transmission into the target gear position. Thus, good fuel economy can be realized together with smooth driving performance even when the vehicle load is changed.

Abstract: A filter device for a fuel tank includes a suction pump main body contained within a fuel tank, a generally cylindrical mounting member mounted upon a bottom portion of the pump main body, and a filter attached to the bottom portion of the pump main body through means of the mounting member. The filter comprises a net. The net is folded over upon itself such that an upper net piece and a lower net piece are vertically overlapped with respect to each other. The upper net piece is formed with a through hole for permitting an upper portion of the mounting member to pass therethrough. The peripheral portions of the net pieces are welded to each other so that the filter is formed as a flat, bag-shaped structure defining an inner enclosed space. The upper portion of the mounting member is connected with the bottom portion of the pump main after passing through the through hole. The inner enclosed space of the filter is in fluid communication with the pump main body by means of the mounting member.

Abstract: In an automatic start controlling apparatus for a vehicle having a friction clutch in which the engaging operation of the clutch is automatically carried out in response to the depression of an accelerator pedal in order to carry out the automatic start operation of the vehicle, the apparatus has a first controller for controlling the engine speed in the isochronous control mode in response to the amount of the depression of the accelerator pedal so as to maintain the engine speed at a target speed and a second controller for controlling the engagement of the clutch by controlling the slip rate of the clutch with the passage of time in accordance with a predetermined characteristics, whereby the engine speed is maintained at the target speed during the operation of the engagement of the clutch. As a result, the change in the slip rate of the clutch follows a constant pattern corresponding the characteristics.

Abstract: In an apparatus for controlling a vehicle clutch which is located between an internal combustion engine and a transmission device whose gear shift position is determined in accordance with the operating position selected by a selector, the apparatus comprises a control signal generator which determines the operating pattern for engaging the clutch in response to at least a position signal showing an operating position selected by the selector and produces a control signal for operating the clutch according to the determined operating pattern in response to the output of a command signal for commanding the beginning of the starting of the vehicle. Thus, the clutch is engaged in accordance with an engaging pattern corresponding to the selected operating position of the selector at that time in response to the output of the command signal.

Abstract: An automatic transmission system for a vehicle in which the gear change operations are carried out in response to a condition signal relating to the speed of an internal combustion engine, which is determined by detecting the operating speed of a brake pedal of the vehicle and a variable filter circuit for receiving the condition signal and for removing any high frequency component of the condition signal, the frequency response characteristics of the variable filter circuit being changeable in response to the operating speed of a brake pedal means.
