20110098881 | VEHICLE CONTROL DEVICE - A vehicle control device having an actuator operative to prevent a movement of a vehicle and a shift operating device including a shift position detection means detecting a shift position, the vehicle control device outputting, when the shift operating device is shift-operated to a predetermined shift position to release prevention of the movement of the vehicle, a control signal for permitting the actuator to release the prevention of the movement of the vehicle, the vehicle control device includes: an abnormality detecting means that detects an abnormality in at least part of the shift position detection means; a shift operation determining means that determines, based on a detection signal from the shift position detection means, whether the shift operating device is shift-operated or not by a driver, and a vehicle movement prevention control means that, in a case where the movement of the vehicle is prevented by the actuator and in a case where the abnormality in part of the shift position detection means is detected by the abnormality detecting means, permits the actuator to release the prevention of the movement of the vehicle if it is determined by the shift operation determining means that the shift operating device is shift-operated by the driver, the shift operation determining means determining that the shift operating device is shift-operated by the driver if the shift position changes from a predefined pre-operation position to a position other than the pre-operation position after the abnormality in part of the shift position detection means is detected by the abnormality detecting means. | 04-28-2011 |

20110202231 | VEHICLE CONTROL DEVICE - An ECU is connected to a multi-system shift sensor detecting a shift lever position in a shift direction associated with detection of the R position, and to a multi-system select sensor detecting a shift lever position in a select direction not associated with detection of the R position. When only one or more, but not all, of sensors in the select sensor are abnormal, the ECU controls the shift range according to the shift position detected based on the remaining proper sensor. When only one or more of sensors in the shift sensor are abnormal, the ECU maintains the current range until an operation of a shift lever is detected, and switches the shift range to the N range at the point of time of detecting an operation of the shift lever. | 08-18-2011 |

20120010793 | SHIFT CONTROL DEVICE FOR VEHICLE - A shift control device for vehicle is provided in which a first operating state (running state of a P-ECU | 01-12-2012 |
20120022756 | SHIFT CONTROL DEVICE FOR VEHICLE - A shift control device is provided for a vehicle of shift-by-wire type having shift operation detecting means electrically detecting a shift operation of a driver, range switching means switching a shift range in response to the shift operation of the driver, failure detecting means detecting a failure in a shift operation detection executed by the shift operation detecting means, and vehicle state detecting means detecting a vehicle state upon detection of the failure in the shift operation detection, the range switching means being switched to a fail-safe mode, when the shift operation detection is recovered from a failed state to a normal state and the range switching means is switched from the fail-safe mode to a normal control mode, a recovery condition for determining switching of the fail-safe mode to the normal control mode being altered depending on the vehicle state. | 01-26-2012 |
