    • A system for selecting between automatic and manual control of a number of gear ratios of a semiautomatic transmission includes an internal combustion engine coupled to a semiautomatic transmission having a number of manually selectable gear ratios and a number of automatically selectable gear ratios wherein the engine and transmission are both subject to management and control thereof by a control computer. A memory unit includes a software algorithm for controlling shifting between the automatically selectable gear ratios and the control computer is operable to execute the software algorithm. A switch is provided, which is preferably a cruise control enable/disable switch, wherein the control computer is responsive to a cruise control disable position of the switch to inhibit execution of the software algorithm and thereby subject the automatically selectable gear ratios to manual control thereof. The control computer is also responsive to a cruise control enable position of the switch to allow execution of the software algorithm to thereby subject the automatically selectable gear ratios to automatic control thereof. In one embodiment, the software algorithm is only inhibited after it has been determined that the engine fueling rate is below a fueling rate threshold if one of the automatically selectable gear ratios is currently engaged. According to another aspect of the invention, a gear down protection algorithm is instituted whenever the software algorithm for controlling automatic gear selection is disabled.
    • 用于在半自动变速器的多个齿轮比的自动和手动控制之间进行选择的系统包括联接到具有多个可手动选择的变速比的半自动变速器的内燃机和多个可自动选择的变速比,其中发动机和变速器 都由控制计算机进行管理和控制。 存储单元包括用于控制可自动选择的传动比之间的换档的软件算法,并且控制计算机可操作以执行软件算法。 提供了一种开关,其优选地是巡航控制启用/禁用开关,其中控制计算机响应于开关的巡航控制禁止位置以禁止软件算法的执行,从而使自动选择的变速比受到其手动控制 。 控制计算机还响应于开关的巡航控制使能位置以允许执行软件算法,从而使自动选择的变速比受到其自动控制。 在一个实施例中,如果当前使用自动可选择的变速比之一,则在确定发动机加油速率低于加油速率阈值之后,仅限制该软件算法。 根据本发明的另一方面,每当禁止用于控制自动档位选择的软件算法时,就进行减档保护算法。

    • A system for controlling automatic transmission downshift points includes a control computer for electronically controlling an internal combustion engine and a transmission having at least one automatically selectable gear. The control computer is responsive to at least a throttle signal, provided by either a manually actuatable accelerator pedal or a cruise control system, to compute an engine load value, and is further responsive to either an engine speed signal or a vehicle speed signal to compute a deceleration value. The control computer is operable to compute a downshift engine RPM value based on the deceleration value and either the throttle signal or the engine load value, wherein the downshift engine RPM value is lower than a default downshift engine RPM if the deceleration value indicates a relatively slow deceleration rate and the throttle signal or the engine load value indicates high throttle or engine load. Conversely, the downshift engine RPM value is higher than the default downshift engine RPM value if the deceleration value indicates a relatively high deceleration rate and the throttle signal or the engine load indicates high throttle or engine load.
    • 用于控制自动变速器降档点的系统包括用于电子控制内燃机的控制计算机和具有至少一个可自动选择的齿轮的变速器。 控制计算机响应至少一个由手动可启动的加速器踏板或巡航控制系统提供的油门信号来计算发动机负载值,并且还响应于发动机转速信号或车速信号来计算 减速度值。 控制计算机可操作以基于减速值和油门信号或发动机负载值来计算降档发动机RPM值,其中如果减速度值指示相对较慢,则降档发动机RPM值低于默认降档发动机RPM 减速率和油门信号或发动机负载值表示高油门或发动机负荷。 相反,如果减速度值指示相对较高的减速率,并且油门信号或发动机负载指示高油门或发动机负载,则降档发动机RPM值将高于默认的降档发动机RPM值。

    • A system for controlling operation of an internal combustion engine includes a control computer responsive to a number of engine/vehicle operating conditions to control engine operation to thereby control engine speed and engine or vehicle acceleration. In one embodiment, the control computer is configured to determine an engine or vehicle acceleration limit value based on current engine or vehicle speed, and an engine speed limit value based on current engine load, and to control engine fueling and/or speed to thereby limit engine speed to the engine speed limit value and/or engine/vehicle acceleration to the engine/vehicle acceleration limit value. In another embodiment, the control computer is configured to determine a pseudo-load value, which is preferably a vehicle mass value and/or road grade value estimated from current vehicle acceleration and engine fueling conditions, determine an engine speed limit value based on the pseudo-load value and current vehicle speed, and control engine speed and/or fueling to thereby limit engine speed to the pseudo-load-based engine speed limit value. In either case, the concepts of the present invention provide for increased fuel economy by limiting engine speed and/or acceleration during shifting, while providing for additional engine speed, and correspondingly higher engine power, when there exists a legitimate need therefore.
