    Abstract: A method is provided to control the acceleration of a motor vehicle from a current speed, wherein the motor vehicle includes an accelerator pedal system able to generate on the accelerator pedal an added reaction force when the depression of the accelerator pedal reaches a given depression level. The method includes the steps of: a) measuring the current vehicle speed; b) determining a target speed of the motor vehicle in function at least of the current vehicle speed or determining from the current vehicle speed a maximum acceleration rate; c) determining at least one threshold depression level of the accelerator pedal that corresponds to the stabilization of the vehicle speed at the target speed or that corresponds to maximum acceleration rate; d) generating an added reaction force on the accelerator pedal if the depression of the accelerator pedal reaches or is about to reach the threshold depression level; wherein at least steps a), b), and c) are automatically repeated as vehicle speed increases.

    Abstract: A method of and system for controlling the speed of a motor vehicle based on a control characteristic so that the speed of the vehicle follows a target speed. The system estimates a dynamic characteristic of the motor vehicle to adjust the control characteristic when the motor vehicle is under a cruising control. The system includes a sensor for detecting a speed of the motor vehicle and a sensor for detecting an operating position of an actuator which adjusts a travelling speed of the motor vehicle. In the system, the detected vehicle speed and actuator operating position are converted into data in terms of an imaginary operating point. The imaginary operating point remains constant because it is not affected by variations of a static characteristic of the motor vehicle. The dynamic characteristic of the motor vehicle is estimated on the basis of the conversion data. This arrangement can accurately estimate the dynamic characteristic of the motor vehicle.

    Abstract: A cruise control system for a vehicle having an internal combustion engine provided with a throttle valve operated by a diaphragm actuator irrespective of a depression of an accelerator pedal by an operator of the vehicle. The system is provided with a system for controlling a vehicle speed in a so-called "dead zone" where hunting usually occurs if a normal feedback control is executed. A time-interval integrating unit is provided for integrating the deviation of the acutal speed with respect to the target speed with a time interval as well as a weight factor, so that the integrated value corresponds to the change in the deviation in the dead zone. The integrated value is compared with a predetermined value corresponding to a change in the vehicle speed which is obtainable when the least significant bit in the control signal output to the actuator is changed. When the integrated value becomes equal to or higher than the predetermined value, the least significant bit is incremented or decremented, and thus speed control in the "dead zone" becomes possible.

    Abstract: A vacuum actuator for actuating the throttle valve of a vehicle is driven by a surge tank via three valves which are actuated by their respective solenoids. These solenoids are energized by their respective driver circuits. The input signal applied to each solenoid is compared with the output signal delivered from the solenoid by a comparator. The comparators for the solenoids are incorporated in a microcomputer. If any one of the comparators indicates disagreement between its two input signals, and if this disagreement persists for a given period, then the microcomputer deenergizes the corresponding solenoid. A timer for measuring the duration of the disagreement is also incorporated in the microcomputer. For example, the invention can be employed in a velocity-sustaining device for a vehicle.

    Abstract: A cruise control system for a vehicle having an automatic transmission comprises a vehicle speed sensor for detecting the actual vehicle speed, an engine output power control mechanism, and a vehicle speed controller which compares the actual vehicle speed detected by the vehicle speed sensor with a set speed and controls the engine output power control mechanism in accordance with the result of the comparison so that the vehicle speed is converged upon the set speed at a predetermined rate. The automatic transmission is caused to downshift when the actual vehicle speed is lowered from the set speed by a predetermined amount while the vehicle speed controller operates to fix the vehicle speed, and when the automatic transmission is shifted down, the predetermined rate of convergence is reduced so that the vehicle speed is converged upon the set speed at a reduced rate.
