Patent number: 11040718Abstract: A launch control method is provided for a vehicle having an accelerator, a brake and a continuously variable transmission (CVT). The method comprises determining: (i) a braking torque set by a vehicle operator by pressing a brake pedal of the vehicle; and (ii) a holding torque required to hold the vehicle in a stationary position. The method also determines that the operator has released the brake pedal. The brake is released whilst engaging a launch clutch of the CVT, wherein the launch clutch is engaged by increasing a clutch engagement pressure at a first pressure ramp rate, such that the sum of the braking torque and a clutch torque of the clutch remains equal to the holding torque. An acceleration torque requested by the operator via the accelerator is determined. The clutch engagement pressure is increased at a second pressure ramp rate when it is determined that the braking torque is substantially zero, such that the clutch torque is increased by the acceleration torque.Type: GrantFiled: September 17, 2018Date of Patent: June 22, 2021Assignee: Perkins Engines Company LimitedInventors: Michael Beyer, Michael Cronin, Steven Spencer, Matthew Mauritzson, Kevin Stutzman

Patent number: 7882920Abstract: A braking force application control is performed when a change in a driver's posture takes place while a brake pedal is turned on when a vehicle is stopped. As a consequence, in a case in which the driver's posture changes such as when the driver turns to a rear seat side to get something without intending to release depression of the brake pedal, creep of the vehicle that the driver does not intend to happen can be inhibited. Furthermore, the vehicle stop retention is only performed when a travelling direction is a forward direction or a seatbelt is worn. As a result, performance of the vehicle stop retention can be inhibited when it is considered that the driver intentionally desires to let the vehicle creep.Type: GrantFiled: November 5, 2008Date of Patent: February 8, 2011Assignees: Advics Co., Ltd., Aisin AW Co., Ltd., Aisin Seiki Kabushiki KaishaInventors: Chihiro Nitta, Kazuhide Adachi, Hideaki Morita, Manabu Matsuda, Kazushi Konno, Shoko Yokoyama

Publication number: 20040067818Abstract: The life of a clutch is prolonged via bypassing a clutch of a gearbox and engaging a machine braking system. A change in speed or direction of a gearbox output shaft is accomplished by a management controller sending a signal through a signal transmission system to bypass the clutch and engage the machine braking system. The method includes the steps of generating a signal; processing the signal by the management controller, sending a signal to bypass the clutch; and sending a signal to engage the vehicle braking system to change the speed or direction of rotation of the gearbox. Because changes of speed and/or direction of rotation of the output shaft are assisted by the machine braking system and the clutch is at least partially bypassed, it is ensured that the braking function of the starting clutch is considerably reduced or even eliminated. This leads to a considerable reduction in wear on the clutch, so that its service life can be greatly increased.Type: ApplicationFiled: October 2, 2002Publication date: April 8, 2004Applicant: CLAAS Industrietechnik GmbHInventors: Robert Obermeier-Hartmann, Ulrich Blumenthal

Patent number: 6155956Abstract: A vehicle equipped with a system (30) for automatically disengaging and engaging a friction clutch (13) coupling between an engine (11) and a transmission (16). The vehicle is also equipped with an automatic brake system (34) for automatically applying and releasing a brake to and from wheels (43). The automatic clutch disengagement/engagement system (30) performs high speed clutch engagement at the time of restarting the vehicle. The automatic brake system (34) releases the brake upon completion of the quick clutch engagement. The quick clutch engagement occurs in a clutch play range. The amount of quick clutch engagement is determined by depression of an accelerator pedal (10). Since the accelerator depression varies from when the vehicle is started on a flat road to when on an inclination, an optimum brake releasing is effected regardless of the road inclination if the timing of brake release is determined in this manner.Type: GrantFiled: March 14, 2000Date of Patent: December 5, 2000Assignee: Isuzu Motors LimitedInventor: Masahiko Hayashi
