Patent number: 8494708Abstract: A controller for determining whether a previously-detected vehicle malfunction still exists. If the malfunction is no longer detected in the sensor signals, a vehicle control system operates in a first operational state or normal operational state with respect to the previously-malfunctioning sensor (e.g., signals from the sensor are used to control the vehicle). If the malfunction continues to be detected, the vehicle control system operates in a second operational state or malfunction state with respect to the malfunctioning sensor in which the signals from the sensor are not used to control the vehicle.Type: GrantFiled: August 20, 2010Date of Patent: July 23, 2013Assignee: Robert Bosch GmbHInventors: Henrik Bechtler, Ravi Bhadange, Nachiket Patil, Takeshi Tokonaga, Stefan Mallmann, Michael Schwab, Dietmar Stapel, Willy Klier, Joerg Eesmann

Patent number: 8489270Abstract: The invention relates to a method and corresponding device for diagnosing the dynamics of an exhaust gas sensor, which is disposed in an exhaust gas duct of an internal combustion engine in the direction of flow of the exhaust gas upstream or downstream of a catalytic converter and with which the air/fuel ratio of the gas mixture supplied to the internal combustion engine is controlled via a control circuit. During diagnosis, provision is made for at least one actuator intervention to be specified by means of a control algorithm of a diagnostic controller specifically m the direction of an asymmetric behavior, which is achieved by an extension of one of the two ramps, until the actuator intervention is compensated by an asymmetric dynamic error of the exhaust gas sensor, a reaction to said actuator intervention being used as criterion for assessing an asymmetric dynamic error of said exhaust gas sensor.Type: GrantFiled: September 28, 2010Date of Patent: July 16, 2013Assignee: Robert Bosch GmbHInventors: Kersten Wehmeier, Michael Pfeil, Siyun Chu, Albrecht Clement

Patent number: 8478474Abstract: A diagnostic apparatus and a diagnostic method are provided for a belt squeezing force adjusting mechanism of a continuously variable transmission in which a belt is wound around a primary sheave that receives driving force and a secondary sheave that outputs force to a drive line, and which continuously changes the output rotation speed by adjusting the width of the groove the primary sheave and the secondary sheave by shift control. This diagnostic determines, as a precondition, whether a target control value calculated in shift control is in a low region, and performs a diagnostic on the belt squeezing force adjusting mechanism based on the relationship between an actual control value and the target control value during control to reduce a control value when it is determined that the precondition is satisfied. According to this diagnostic apparatus and diagnostic method, an erroneous diagnosis can be prevented so the diagnostic can be performed accurately.Type: GrantFiled: January 30, 2009Date of Patent: July 2, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yasunari Matsui, Akira Hino, Shinya Toyoda, Naoto Tanaka

Patent number: 8467929Abstract: A controller for determining whether a previously-detected vehicle wheel speed sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one wheel speed sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one wheel speed sensor. A tell-tale indicator is deactivated and/or a vehicle control system resumes normal operation if the wheel speed sensor passes the signal check.Type: GrantFiled: August 20, 2010Date of Patent: June 18, 2013Assignee: Robert Bosch GmbHInventors: Henrik Bechtler, Ravi Bhadange, Nachiket Patil, Takeshi Tokonaga, Stefan Mallmann, Michael Schwab, Dietmar Stapel, Willy Klier, Joerg Eesmann

Patent number: 8447460Abstract: A control state of the vehicle is switched upon operation of a control switch. Besides, a mode of travel for a travel of a vehicle is selected by operation of a travel mode selection portion. Then, it is determined whether the recommended control state recommended for the selected mode of travel and the actual control state are the same. If it is determined that they are not the same, that is, that there is a deviation between the recommended control state and the actual control state, an operation method for a control switch for realizing the control state recommended for the selected mode of travel is presented to a driver.Type: GrantFiled: November 4, 2008Date of Patent: May 21, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshihisa Nihei, Yasushi Kobayashi

Patent number: 8447418Abstract: A control system has regular ECUs and a recovery ECU. Each regular ECU controls driving of current consumers, respectively, drivable by driving methods and connected through output channels. The recovery ECU has output drivers, respectively, producing driving currents based on the driving methods and channel changing blocks corresponding to the respective driving methods. When receiving information indicating failure of an output channel of one regular ECU, the recovery ECU specifies the driving method of the failed channel, controls the driver of the specified driving method to produce a driving current, and controls the changing block of the specified driving method to select one output channel, through which the current consumer connected with the failed ECU through the failed channel is also connected with the changing unit. The recovery ECU performs substitute driving instead of the failed ECU to supply the current to the consumer.Type: GrantFiled: March 1, 2011Date of Patent: May 21, 2013Assignee: Denso CorporationInventor: Kenji Katou
