摘要： A control system is provided for a vehicle regulating engine speed during shifts so as to reduce driveline torque and shift shock. The control system includes separate microprocessor based engine and transmission controllers which communicate via a data link. When a shift is initiated, the transmission controller delays a period of time sufficient for the transmission to disengage the old gear ratio and then produces a CTSSPEED signal. The transmission controller continues to produce the CTSSPEED signal for a second period of time which corresponds to the time required for the transmission to engage the new gear ratio.The engine controller receives the desired engine speed signal and regulates engine speed into correspondence with the desired speed. During upshifts, the CTSSPEED signal is set to a speed which is a predetermined amount above the synchronization speed of the new gear for an upshift. Conversely, during downshifts, the CTSSPEED is set to a speed which is a predetermined amount below the synchronization speed in the new gear.
摘要翻译： 提供一种控制系统，用于在换档期间调节发动机转速的车辆，以减少传动系扭矩和换档冲击。 控制系统包括通过数据链路进行通信的基于微处理器的引擎和传输控制器。 当发生换挡时，变速器控制器延迟足够的时间以使变速器脱离旧齿轮比，然后产生CTSSPEED信号。 变速器控制器继续产生CTSSPEED信号第二个时间段，这对应于变速器接合新传动比所需的时间。 发动机控制器接收期望的发动机速度信号并且将发动机速度调节为与期望速度相对应。 在升档期间，CTSSPEED信号被设定为高于用于换高档的新档的同步速度的预定量的速度。 相反，在降挡期间，CTSSPEED被设定为低于新齿轮中的同步速度的预定量的速度。
