Patent number: 7323976Abstract: A control system (18) for an automotive vehicle (10) has a first roll condition detector (64A), a second roll condition detector (64B), a third roll condition detector (64C), and a controller (26) that uses the roll condition generated by the roll condition detectors (64A-C) to determine a wheel lift condition. Other roll condition detectors may also be used in the wheel lift determination. The wheel lift conditions may be active or passive or both.Type: GrantFiled: July 31, 2006Date of Patent: January 29, 2008Assignee: Ford Global Technologies LLCInventors: Jianbo Lu, Michael Edward Brewer, Todd Allen Brown, Joseph Carr Meyers

Patent number: 7308351Abstract: A vehicle dynamics control system for a motor vehicle having an active normal force adjustment system with which the normal force acting on a wheel may be adjusted is described. For coordinating the vehicle dynamics control system with the active normal force adjustment system, information about a change in the normal force is to be supplied to a control unit of the vehicle dynamics control system and may be taken into account in the vehicle dynamic control.Type: GrantFiled: June 23, 2004Date of Patent: December 11, 2007Assignee: Robert Bosch GmbHInventors: Michael Knoop, Martin Kieren, Andreas Schumann

Patent number: 7269494Abstract: A method of estimating the slope of a road surface on which is positioned a motor vehicle. The slope is determined by measuring the velocity and longitudinal acceleration of the vehicle by means of a mathematical model based on the relation Ax={dot over (?)}+g sin ?, where Ax is longitudinal acceleration, {dot over (?)} indicates the component of longitudinal acceleration of the vehicle along the road surface, g is the gravitational acceleration, and ? represents the angle of inclination of the road surface.Type: GrantFiled: September 13, 2006Date of Patent: September 11, 2007Assignee: C.R.F. Societa Consortile per AzioniInventors: Emanuel Corigliano, Pandeli Borodani

Patent number: 7239952Abstract: A system that detects a lateral acceleration and roll rate of the vehicle and estimates a mass distribution parameter. The system then generates a tuned mass distribution parameter that is based on the the lateral acceleration, the roll rate, and the mass distribution parameter and introduces the tuned mass distribution parameter to a rollover stability control system.Type: GrantFiled: December 8, 2004Date of Patent: July 3, 2007Assignee: Continental Teves, Inc.Inventor: Geoffrey Burke Bauer

Patent number: 7233235Abstract: Method and devices for disabling detection of a safety system activation condition. One embodiment of the invention provides a method that includes disregarding information from a first set of sensors when detection of a safety system activation condition is disabled; determining if information from a second set of sensors in available; when information from a second set of sensors is not available, generating a warning signal; when information from the second set of sensors is available, determining a value of the information from the second set of sensors; and when the value of the information from the second set of sensors indicates that a vehicle is in use, enabling detection of the safety system activation condition.Type: GrantFiled: November 1, 2004Date of Patent: June 19, 2007Assignee: Robert Bosch GmbHInventor: David L. Pavlish

Patent number: RE40268Abstract: A system for detecting wheel lift of an automotive vehicle has a speed sensor (22) coupled to a wheel (12) of automotive vehicle (10). A torque control system (20) is coupled to wheel (12) to change the torque at the wheel. A controller (18) is coupled to the torque control system and a speed sensor. The controller (18) determines lift by changing the torque of the wheel, measuring the change in torque and indicating lift in response to change in torque which may be indicated by wheel speed.Type: GrantFiled: December 21, 2004Date of Patent: April 29, 2008Assignee: Ford Global Technologies, LLCInventors: Joseph Carr Meyers, Todd Allen Brown
