摘要:
A failure determination threshold value HSH used for making a failure determination for a control apparatus, for example, a lock-up clutch (26) by failure determining means (116) is corrected by failure determination threshold value correcting means (114) based on a continuation quantity qNG, for example, a duration tNG, of an operation state in which a predetermined failure precondition for the control apparatus mounted on a vehicle is satisfied. Therefore, a failure determination is performed by the failure determining means (116) using the failure determination threshold value HSH obtained in consideration of individual differences such as variations between vehicles. As a result, it is possible to prevent an erroneous determination regarding a failure, and to improve sensitivity of a failure determination.

An electronic control unit is provided with two types of gear change maps: a first gear change map based on the vehicle speed and the accelerator pedal operation amount; and a second gear change map based on the vehicle speed and the required drive force of the vehicle. The electronic control unit determines whether the automatic transmission should downshift with reference to the first gear change map, and determines whether the automatic transmission should upshift with reference to the second gear change map.

A shift output torque control unit executes a shift output torque control to control an engine torque so as to reduce a driving force difference, which is a variation width of a driving force due to downshift of an automatic transmission. Thus, in comparison with the case in which the shift output torque control is not executed, it is possible to smooth a variation in driving force associated with the downshift. As a result, occupants' comfort and controllability to driving operation may be improved.

A control apparatus for a hybrid vehicle provided with an electrically operated continuously-variable transmitting portion and a step-variable transmitting portion, which control apparatus permits an adequate control of a shifting action of the step-variable transmitting portion, while reducing deterioration of fuel economy of the hybrid vehicle.The control apparatus is configured to implement concurrent controls of a movement of an operating point of an engine and a shifting action of the step-variable transmitting portion, such that an electric energy generation/consumption balance value in an overall transmission mechanism consisting of the electrically operated continuously-variable transmitting portion and the step-variable transmitting portion is controlled by controlling a change of a rotary motion of each of at least one of a sun gear corresponding to a g-axis, a carrier corresponding to an e-axis and a ring gear corresponding to an m-axis, so that a shifting shock of the step-variable transmitting portion can be reduced while controlling the electric energy generation/consumption balance to a desired value.

A power transmission controlling apparatus of a vehicle includes a clutch capable of connecting/disconnecting power transmission between an engine and a motor/generator, and a torque converter enabling power transmission between the engine or/and the motor/generator and an automatic transmission. When the engine is started by motoring torque with engagement of the clutch during rotation of the motor/generator, the power transmission controlling apparatus sets a torque compensation amount by the motor/generator based on an estimated torque capacity of the clutch, and suppresses torque fluctuations on a power transmission path accompanying engagement of the clutch by power of the motor/generator containing the torque compensation amount. The power transmission controlling apparatus corrects the torque capacity or the torque compensation amount based on input torque of the torque converter.

A vehicle information record-collection system includes a plurality of drive recorders, and a center system. The center system sends setting change request information that includes vehicle information designated to be a record object to the drive recorder of each investigation object vehicle through wireless communication. The drive recorder of each vehicle, upon receiving the setting change request information from the center system through wireless communication, changes the setting of the vehicle information in terms of the record object on the basis of the setting change request information. After the setting change in terms of the record object, the drive recorder records the vehicle information, and sends the recorded vehicle information to the center system through wireless communication.

Disclosed is a slip detecting device for a motor vehicle mounted with an automatic transmission. The slip detecting device is provided with a device for detecting a rotational speed of the specific part in a driving system, whereby occurrence of a driving wheel slip is detected based on the speed variation state in the rotational speed such as the gradient of variation in the output shaft rotational speed when shifting. Therefore, a driving wheel slip can be detected at a low cost, regardless of the accelerator pressed condition.

In order to correctly detect the frictional state of a running road surface, the running road surface is determined as a low-friction road surface, when tire lock is detected by tire lock detection device, and besides a state in which vehicle deceleration obtained by vehicle deceleration detection means is greater than a predetermined value, is shorter than a predetermined time in a period extending from the start of braking until the tire lock.
