Patent number: 11002635Abstract: A lean signal processing method, a bearing monitoring unit and a wheel monitoring unit using the lean signal processing method are presented that are especially suitable for embedded systems. The invention is based on the basic inventive idea of digitally adjusting measured signals that are to be analyzed in different frequency bands to thereby enable to have a single common analogue front end and a single common digital spectrum analyzer back end. This will save analogue components and relax the need for memory in addition to a lean signal processing.Type: GrantFiled: March 14, 2019Date of Patent: May 11, 2021Assignee: Aktiebolaget SKFInventors: Simon Hubert, Jens Graf, Damien Joucgnoux

Patent number: 8352126Abstract: The system of the invention includes sensors (11, 12, 13) for measuring physical values useful for driving assistance, a path correction electronic calculator (20) including a Hill Assist (HA) module for hill start assistance and a Hill Descent Control module for limiting the downhill speed, and actuators (31 to 35) controlled by said calculator for acting on the different driving parameters. The calculator further includes a Hill Assist Descent Control (HADC) for driveability control assistance in slopes, that enables or disables the Hill Assist (HA) and Hill Descent Control (HDC) modules based on specific control rules for managing intermediate life situations between the situations managed by the Hill Assist (HA) module and those managed by the Hill Descent Control (HDC) module. The invention also relates to automobiles and to automobile driving assistance systems.Type: GrantFiled: April 9, 2008Date of Patent: January 8, 2013Assignees: Peugeot Citroen Automobiles SA, Robert Bosch GmbHInventors: Philippe Blaise, Emmanuel Charpin, Damien Joucgnoux

Patent number: 8275532Abstract: An anti-skid device for the driving wheels (10) of a vehicle, in particular an automotive vehicle, includes an active braking device (16) of the torque to be transmitted to the driving wheels; a torque regulator (12) providing a control signal (Cb) to the active braking device (16) according to information on the regulation deviations (?v) relative to a set predetermined regulation; a control unit (20) providing the regulator (12) with regulation initialization information (In). The control unit (20) obtains the regulation initialization information (In) from evolution parameters of the vehicle on all terrains, such as the adhesion and the speed of the driving wheels, the slope and/or slant of the terrain. Application: anti-skid device for the wheels of an automotive vehicle.Type: GrantFiled: August 10, 2007Date of Patent: September 25, 2012Assignees: Peugeot Citroen Automobiles SA, Robert Bosch GmbHInventors: Philippe Blaise, Emmanuel Charpin, Damien Joucgnoux
