Patent number: 6847880Abstract: A vehicle speed control system for a vehicle with an engine and an automatic transmission is comprised of a coast switch for decreasing a set vehicle speed and a controller connected with the coast switch. The controller controls a vehicle speed at the set vehicle speed by controlling the engine and the automatic transmission, and maintains a gear ratio of the automatic transmission at the gear ratio set at the moment before decreasing the set vehicle speed when the coast switch is being operated to decrease the set vehicle speed. Therefore, even if the throttle opening is opened to accelerate the vehicle, the engine rotation speed is never radically increased under such a transmission condition. This prevents the engine from generating noises excessively.Type: GrantFiled: May 14, 2001Date of Patent: January 25, 2005Assignee: Nissan Motor Co., Ltd.Inventors: Takeshi Ishizu, Kazutaka Adachi, Junsuke Ino, Hideki Sudo

Patent number: 6746368Abstract: A vehicle speed control system is adapted to a vehicle equipped with an automatic transmission with a torque converter. The vehicle speed control system detects whether the automatic transmission is put in a lock-up condition, and corrects a command drive torque according to the lock-up condition of the automatic transmission. Particularly, the vehicle speed control system decreases a correction quantity of the command drive torque when the automatic transmission is put in the un-lockup condition. Therefore, the vehicle speed control system can adapt its response characteristic to a controlled system response characteristic which varies according to the lock-up condition of the transmission.Type: GrantFiled: May 14, 2001Date of Patent: June 8, 2004Assignee: Nissan Motor Co., Ltd.Inventors: Kazutaka Adachi, Hideki Sudo, Junsuke Ino, Takeshi Ishizu

Patent number: 6732039Abstract: A vehicle speed control system is installed to a vehicle equipped with an engine and a continuously variable transmission (CVT). The vehicle control system is comprised of a controller arranged to execute a vehicle speed control, to suspend the vehicle speed control when a throttle opening is increased to be greater than a target throttle opening for the vehicle speed control and to restart the suspended vehicle speed control when the throttle opening becomes smaller than the target throttle opening. Further, the controller is arranged to decrease the throttle opening and to execute a shift down of the CVT when the vehicle speed at the moment of restarting the vehicle speed control is greater than or equal to the target vehicle speed. Therefore, this vehicle speed control system can quickly and smoothly decelerate the vehicle without generating shift shocks when the vehicle speed control is restarted.Type: GrantFiled: January 11, 2002Date of Patent: May 4, 2004Assignee: Nissan Motor Co., Ltd.Inventors: Junsuke Ino, Kazutaka Adachi, Takeshi Ishizu, Hideki Sudo

Patent number: 6076172Abstract: Accompanied by turning on power, power ON reset pulse from a power ON reset generation circuit is input to CPU and a fail determining circuit. After receiving the power ON reset pulse, the fail determining circuit intentionally outputs a fail detection signal. The CPU intentionally stops output of PRUN signal after confirming that fail detection signal. WDT confirms that output of the PRUN signal from the CPU is stopped in a predetermined time interval T and outputs PRUN abnormality signal. A reset pulse generation circuit confirms that PRUN abnormality signal is supplied from the WDT and outputs a reset pulse. A fail determining circuit receives a reset pulse and stops output of fail detection signal. When the fail determining circuit stops output of the fail detection signal, the CPU determines that the WDT, the reset pulse generation circuit and the fail determining circuit are in normal state.Type: GrantFiled: April 9, 1997Date of Patent: June 13, 2000Assignee: Nissan Motor Co., Ltd.Inventors: Takashi Kimura, Junsuke Ino
