摘要： An electronic control (31) is provided for a vehicle (10) having an engine (12), a main drive (14) driven by the engine (12), a fluid pump (36) driven by the engine (12) for providing pressurized fluid, and a supplemental drive driven (30) by the pressurized fluid. The electronic control (31) includes a main drive sensor (54) for sensing the speed of the main drive (14) and responsively producing a main drive speed signal. A vehicle speed sensor (64) senses the speed of the vehicle (10) relative to the ground and produces a vehicle ground speed signal. A pressure sensor (74) senses the pressure of the pressurized fluid supplied to the supplemental drive (30) by the pump (36) and responsively produces an actual pressure signal. A processor (52) receives the main drive speed, vehicle ground speed, and actual pressure signals, produces a slip ratio signal responsive to a ratio of the main drive speed and vehicle ground speed signals, produces a desired pressure signal responsive to the slip ratio signal, produces an error signal responsive to a difference between the desired and actual pressure signals, and controls the fluid pressure in the supplemental drive (30) in response to the error signal.

摘要： A control system (30) is provided for a vehicle (10) regulating engine speed during shifts so as to reduce driveline torque and shift shock. The control system (30) includes separate microprocessor based engine and transmission controllers (32, 34) which communicate via a data link. When a shift is initiated, the transmission controller (34) delays a period of time sufficient for the transmission (14) to disengage the old gear ratio and then produces a CTSSPEED signal. The transmission controller (34) continues to produce the CTSSPEED signal for a second period of time which corresponds to the time required for the transmission (14) to engage the new gear ratio. The engine controller (32) receives the desired engine speed signal (NOP) and regulates engine speed (NA) 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：为车辆（10）提供控制系统（30），用于调整变速时的发动机转速，以减少传动系扭矩和换档冲击。控制系统（30）包括经由数据链路进行通信的分离的基于微处理器的发动机和变速器控制器（32,34）。当发生换档时，变速器控制器（34）延迟足够的时间以使变速箱（14）脱离旧的齿轮比，然后产生CTSSPEED信号。变速器控制器（34）继续产生CTSSPEED信号，该第二时间段对应于变速器（14）接合新传动比所需的时间。发动机控制器（32）接收期望的发动机转速信号（NOP）并且调节与期望速度相对应的发动机转速（NA）。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。
