  • Patent number: 6847880
    Abstract: A vehicle speed control system for a vehicle with an engine and an automatic transmission is comprised of a coast switch for decreasing a set vehicle speed and a controller connected with the coast switch. The controller controls a vehicle speed at the set vehicle speed by controlling the engine and the automatic transmission, and maintains a gear ratio of the automatic transmission at the gear ratio set at the moment before decreasing the set vehicle speed when the coast switch is being operated to decrease the set vehicle speed. Therefore, even if the throttle opening is opened to accelerate the vehicle, the engine rotation speed is never radically increased under such a transmission condition. This prevents the engine from generating noises excessively.

  • Patent number: 6591181
    Abstract: A method and a device are for setting the longitudinal speed of a vehicle to a setpoint speed, in particular on the basis of a regulation, having controllable brakes. In operation of a cruise control system, the cruise control may be activated when the instantaneous driving speed is significantly higher than a stored setpoint speed. In this situation, there may be unwanted braking responses by the regulator, which may endanger the driver and the following road users. In such a situation, the method prevents a breaking measure from being implemented and ensures that the vehicle will coast, being braked only by the road resistance and the drag on the engine, until reaching the set speed. The driving response of the cruise control system approximates that of a human driver, so the responses of the automatic cruise control seem more intelligible for the driver.

    Abstract: A vehicle travel control apparatus makes an own vehicle automatically follow a vehicle in front by setting a target acceleration/deceleration G0 using travel data expressing behavior of the vehicle, travel environment, driving operations and others. Here, during vehicle travel based on driver control, multiple travel data are sampled a predetermined number of times to perform multiple regression analysis on that sampled data. Preference data expressing preferences of the driver (multiple regression coefficients) are thereby obtained, and target acceleration/deceleration computation data are updated using these multiple regression coefficients. As a result, it is possible to control the behavior of the vehicle in accordance with preferences of the driver during automatic following control execution.

    Abstract: The speed of an automobile is limited by a throttle controller between the gas pedal and the throttle valve. The controller is actuated by a digital or analog processor in a speed limiter control module. The speed limiter control module receives vehicle speed and has a maximum speed input device such as a keypad and a readout display panel which indicates the maximum speed set. When the vehicle speed exceeds the set speed, the throttle controller disengages the gas pedal from the throttle valve to prevent the gas pedal from causing further speed increase. The speed limiter control module is lockable so that only authorized persons are allowed to reset the maximum speed. This allows the owner to preset a maximum speed and loan the automobile to his offspring or others knowing that they will be speed limited. In the same manner, maximum acceleration and/or engine RPM can be preset and controlled.

  • Patent number: 6473684
    Abstract: To provide an auto-cruise canceling device for maintaining a good operating response of the vehicle. A DC servo-motor is used as an actuator for regulating a throttle opening during auto-cruising. When a throttle grip is turned during regulation of the throttle opening by the servo-motor, namely, during a cruising state, a turning force transmitted to a throttle drum through a throttle cable causes a variation in the load on the motor. An ECU detects load variations based on the current in the servo-motor. If the load variation is not less than a predetermined value, it is judged that a rider's cruise canceling action has been made, and bias of the servo-motor is stopped, thereby canceling the cruising state.

  • Publication number: 20020120385
    Abstract: A method and apparatus for controlling the throttle position of a vehicle by modifying the pedal to throttle progression typically used by the electronic throttle controller to a throttle progression based on the driver's target acceleration and vehicle speed. Target acceleration is determined using a lookup table with inputs current vehicle speed and accelerator pedal displacement. Another lookup determines the end vehicle speed the driver will attain if the pedal displacement does not change. A signal indicating the new throttle position is the output of a controller whose input is the difference between end vehicle speed and current vehicle speed and whose gain is based on the target acceleration. Changes in throttle position can be limited based on an arbitration incorporating information received from other vehicle control systems. Preferably, control of the throttle will revert to the idle control system whenever the accelerator pedal is not displaced.

  • Patent number: 6427111
    Abstract: A process for the automatic regulation of the distance between a vehicle to be regulated and another vehicle is employed in a vehicle which has a distance regulating device and a braking system which is actuable by the distance regulating device. When the distance regulating device emits a brake actuation signal to the braking system, a brake control device actuates the brakes thereby regulating the distance between the vehicle to be regulated and the other vehicle. Prior to emitting the brake actuation signal, the distance regulating device emits a braking readiness signal to the braking system thereby causing the braking system to assume a braking readiness state. The distance regulating device emits the braking readiness signal when it detects, based on the travel and road conditions surrounding the vehicle to be regulated, that braking will occur shortly.

  • Patent number: 6418370
    Abstract: A distance control is performed to maintain a target distance between two traveling vehicles by controlling an acceleration/deceleration actuator based on a physical quantity representing an actual distance between the two traveling vehicles. A temporary distance control is performed to suppress a deceleration degree of a succeeding vehicle to a smaller value compared with a deceleration degree attainable during an ordinary distance control, when the two traveling vehicles are departing from each other under a condition where the actual distance between the two traveling vehicles is already shorter or will soon become shorter than a standard target distance.

  • Patent number: 6405820
    Abstract: The invention relates to a distance-related electronic driving speed regulating system for motor vehicles, wherein a predetermined constant speed is maintained during a first regulating mode until a predetermined minimal distance to a preceding vehicle is reached or surpassed. When the predetermined minimal distance is reached or surpassed during a second regulating mode, the speed is regulated in such a way that the predetermined minimal distance is maintained in the form of a distance-regulated follow-on drive. If the gas pedal is actuated during the first or the second regulating mode to accelerate to an increased actual speed exceeding the momentarily predetermined speed, a new speed is predetermined by actuating a set operating element depending on the increased actual speed.

  • Patent number: 6405119
    Abstract: In a method for limiting the traveling speed of a motor vehicle to a variable maximum speed a limiting system action takes place in the situation where the speed demanded by the driver via the actual accelerator pedal position is higher than the preset maximum speed. In this case, taking account of vehicle state and operating variables, control signals can be produced in order to select a specific gear in the transmission. At the time when the preset maximum speed is switched off, an accelerator pedal substitute variable which correlates with the preset maximum speed is compared with an actual accelerator pedal position. When the actual accelerator pedal position is greater than the accelerator pedal substitute variable at the time when the maximum speed is switched off, a defined minimum gear is preset as the lower gear limit in the transmission.
