    • The invention relates to a method for cruise control of an automotive vehicle, including: determination of a target value (vtar) stating a desired velocity of the vehicle, determination of an actual value (vact) stating the current speed of the vehicle, repeated calculation of an integrated control factor (Ip ) in dependence of the current difference between said actual value (vact) and said target value (vtar), and generation of an output signal ( alpha ) from a control unit (1) in dependence of the size of said control factor (Ip ), said output signal ( alpha ) being utilised for controlling the vehicle engine (2) to a corresponding output torque. The invention is characterised by including a limitation of said integrated factor (Ip ) to a maximum value, preselected in dependence of the current rotational speed (n) of said engine (2). The invention also relates to a device for cruise control. Thanks to the invention, an improved cruise control is provided, with an optimum tuning of said integrated control factor.

    • Control unit (1) for a cruise control system for a motor vehicle including at least one manually operated movable switch (4) for operating the cruise control system. The switch (4) has a neutral position (6) and can, when moved away from the neutral position (6) in a first direction, assume a first position (8) in which the switch (4) gives a control unit (21) a signal for temporarily switching off the system without cancellation of set speed. The switch (4) can also, when moved away from the neutral position (6) in the first direction, assume a second position (10) in which the switch (4) conveys signals to the control unit (21) in order to facilitate for the cruise control system to access, in some predetermined manner, a set speed stored in a memory unit situated in the control unit (21), where the second position (10) can only be reached by the switch (4) passing through the first position (8).
    • 一种用于机动车辆巡航控制系统的控制单元(1),包括用于操作巡航控制系统的至少一个手动操作的可移动开关(4)。 开关(4)具有中间位置(6),并且当第一方向移动离开中立位置(6)时,可以采用第一位置(8),开关(4)在其中给出控制单元(21) )用于暂时关闭系统而不取消设定速度的信号。 开关(4)也可以在第一方向远离中立位置(6)移动时采取第二位置(10),开关(4)将信号传送到控制单元(21),以便于 用于巡航控制系统以某种预定的方式访问存储在位于控制单元(21)中的存储单元中的设定速度,其中第二位置(10)只能由穿过所述控制单元的开关(4)到达 第一名(8)。

    • A speed management device for limiting a motor vehicle to a predetermined speed comprising an apparatus for interfacing a throttle with a control therefor. The apparatus comprises a linkage including a solenoid (143) for selectively connecting and disconnecting the throttle from the control, and a sensing means in the form of a microswitch (151) to sense a relative position at which the solenoid (143) may operate to latch the linkage. The apparatus includes a circuit (173) for operating the solenoid (143), and controlling a servo (127) which controls the throttle to maintain the predetermined speed while the linkage disconnects the throttle from the control. Instantaneous speed information is derived by the circuit (173) from a speed sensor (175), and the predetermined speed is selected on a selector arrangement (177). An option switch (179) is provided to enable or disable the function of the device, and to select other functions that the device may optionally possess. The device functions by operating the solenoid (143) when the circuit (173) determines that the predetermined speed has been reached, and overrides control of the throttle from the driver until the driver desires to slow the vehicle, at which point the circuit (173) senses the relative position and deactuates the solenoid (143) to restore control of the vehicle speed to the driver. An "impact drive" bistable solenoid is also disclosed.
    • 一种用于将机动车限制到预定速度的速度管理装置,包括用于将节气门与其控制接口的装置。 该装置包括一个联动装置,该联动装置包括用于选择性地将节气门与控制器连接和断开的螺线管(143)和微型开关(151)形式的感测装置,用于感测螺线管(143)可操作的相对位置 锁定连杆。 该装置包括用于操作螺线管(143)的电路(173),并且控制在控制器将节流阀与控制装置断开的情况下控制节气门以维持预定速度的伺服机构(127)。 由速度传感器(175)的电路(173)导出瞬时速度信息,并且在选择器装置(177)上选择预定速度。 提供选项开关(179)以使能或禁用装置的功能,并且选择装置可选择地拥有的其他功能。 当电路(173)确定已经达到预定速度时,该装置通过操作螺线管(143)起作用,并且重写来自驾驶员的节流阀的控制,直到驾驶员期望使车辆减速,此时电路(173 )感测相对位置并且停用螺线管(143)以恢复对驾驶员的车辆速度的控制。 还公开了一种“冲击驱动”双稳态螺线管。
