Patent number: 7503876Abstract: In a departure standby state in which a transmission is shifted to a drive stage and a mechanical clutch is disengaged, if a vehicle speed is greater than or equal to a predetermined value, the transmission is shifted to the neutral, and then the mechanical clutch is engaged. Then, it is determined whether the transmission is being rotated in reverse or not based on a rotational fluctuation on the driving side or the driven side in the process for engaging the mechanical clutch. When an accelerator pedal is pressed down at an angle greater than or equal to a predetermined angle, or when a gear shift instruction is input from the shift lever, if the transmission is being rotated in reverse the transmission is inhibited from being shifted to the drive stage, while if the transmission is not being rotated in reverse the transmission is shifted to the drive stage according to the pressed down state of the accelerator pedal, or a gear shift in instruction.Type: GrantFiled: March 29, 2005Date of Patent: March 17, 2009Assignee: Nissan Diesel Motor Co., Ltd.Inventors: Toshio Kitamura, Isao Okamoto, Osamu Isobe, Akihisa Hayashi, Yuuichi Ichikawa

Patent number: 7311637Abstract: In an automatic transmission control system, an operating amount of a throttle due to a driver's depression of an accelerator pedal is detected, and the rotating number of an engine suitable for the detected throttle operating amount is detected. The automatic transmission control system includes a shift map defined by the throttle operating amount and the engine rotating number. The actuation of upshift or downshift of a transmission is automatically controlled based on the shift map. The driver can be informed of a point where a shift map is switched by a depression operation of the accelerator pedal so that generation of unnecessary downshift and delay of upshift are prevented to allow a vehicle to be efficiently driven.Type: GrantFiled: September 27, 2005Date of Patent: December 25, 2007Assignee: Nissan Diesel Motor Co., Ltd.Inventors: Toshio Kitamura, Yuuichi Ichikawa, Akihisa Hayashi, Isao Okamoto, Osamu Isobe

Patent number: 7261673Abstract: In an automatic transmission having a clutch and a gear type transmission, a control unit for inputting detected signals from the operating condition detecting device, and outputting control signals to the gear changing device and the clutch drive device based on the detected signals. The control unit determines whether a stop intention condition of a driver is satisfied or not, and performs first gear change control for, if the stop intention condition is determined to be satisfied, disengaging the friction clutch and changing the gear type transmission to a neutral position, and second gear change control for, when an accelerator opening becomes greater than or equal to a predetermined value, after the friction clutch is disengaged and the gear type transmission is changed to the neutral position by the first gear change by the first gear change control, changing the gear type transmission to a gear according to a vehicle speed, and engaging the friction clutch.Type: GrantFiled: October 21, 2003Date of Patent: August 28, 2007Assignee: Nissan Diesel Motor Co., Ltd.Inventors: Toshio Kitamura, Yuuichi Ichikawa, Akihisa Hayashi, Isao Okamoto, Osamu Isobe
