  • Patent number: 10166953
    Abstract: When a P lock state is set on the basis of a predetermined request signal for setting the P lock state, a P position indicator lamp (62) is turned on or off on the basis of the status of power supplied to the vehicle (10). For example, when the P lock state is set, the P position indicator lamp (62) is turned off when the power status is an ALL-OFF status where a combination meter (56), or the like, is not turned on or is raised to an ACC-ON status; whereas, when the P lock state is set, the P position indicator lamp (62) is turned on when the power status is an IG-ON status, when the power status is changed from the IG-ON status during vehicle driving to the ACC-ON status, or within a predetermined period of time from when the power status is changed from the IG-ON status to the ALL-OFF status.

  • Patent number: 9611932
    Abstract: When initial drive control for an actuator driving a shift switch mechanism is completed, a P-ECU determines whether an IG signal is received. In the case where the P-ECU has not received the IG signal at the time when the initial drive control is completed, the P-ECU temporarily keeps the actuator in a state where the initial drive control is completed. In the case where the P-ECU receives the IG signal in the period from completion of the initial drive control to the time when a predetermined time T2 has elapsed since completion of the initial drive control, the P-ECU executes P wall press control when the P-ECU receives the IG signal.

  • Patent number: 9221350
    Abstract: When a charge connector has been removed from a vehicle-side connector while parking lock is set, an ECU determines whether or not there is return history that a momentary shift lever has moved to a home position after removal of the charge connector from the vehicle-side connector. When there is return history and when a brake-on state is set, the shift lever has been operated from the home position to any position of N, D and R, and the resultant position is continuously maintained for a prescribed period of time, the ECU unlocks the parking lock.

  • Patent number: 8914185
    Abstract: 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.

  • Patent number: 8738253
    Abstract: An ECU controls an automatic transmission that can be manually shifted. The ECU executes a program that includes i) the step of, when there are a plurality of allowed gears that are allowed at the time of a downshift operation, continuously determining whether the engine speed NE after a downshift will be in a preset overspeed region for each allowed gear when the second and subsequent allowed gears are lower than an output gear, and when there is an allowed gear that will result in the engine speed NE being in the overspeed region, ii) the step of cancelling that allowed gear. Thus this control appropriately suppresses overspeeding of the engine while executing a manual shift in response to an operation by the driver without bothering the driver.

  • Patent number: 8630775
    Abstract: When an automatic transmission is in a manual mode, a transmission ECU calculates a speed sftrng manually requested by the driver and a speed sftrngmap set by a shift map and then performs a shift prohibition procedure. In this procedure, if the engine coolant temperature is equal to or lower than a predetermined coolant temperature or the AT fluid temperature is equal to or lower than a predetermined fluid temperature, a prohibition, determination flag xthlow is set to “on”, and if the engine coolant temperature is higher than the predetermined coolant temperature and the AT fluid temperature is higher than the predetermined fluid temperature, the prohibition determination flag xthlow is set to “off”. When the prohibitions determination flag xthlow is “on”, the speed sftrngmap is set as the upper limit of the speed sftrng.

  • Patent number: 8265840
    Abstract: A control device for an automatic transmission is disclosed wherein a shift point depending on a variation in vehicle acceleration is modified on a real time basis in accordance with not only a corrected result on a shift point depending on piece-to-piece variations of automatic transmissions, but also actual acceleration for shortening a time required for learning with high precision with no need to be matched. Shift point real-time modifying means is provided for modifying the altered shift point based on a value of a ratio between a value of actual engine-rotation acceleration at an upshift-determining timing during a power-on running and a value of reference engine-rotation acceleration obtained by substituting a value of actual engine-rotation acceleration to a value for a reference running state having no impact on acceleration of a vehicle, and a target maximum engine rotation speed.

  • Patent number: 8175778
    Abstract: If a mode-detection value is switched from an automatic shift-mode to a manual shift-mode, a T-ECU changes a shift-stage to a speed lower than a speed that is obtained before the switching of the mode-detection value. The T-ECU determines that a state of the T-ECU returns to a recognizable-state, in which a mode-selection value can be recognized, from an unrecognizable-state, in which the mode-selection value cannot be recognized. The T-ECU sets the shift-stage to a hold value after the return. The T-ECU controls the shift-stage in the automatic shift-mode “D” over a standby-period after the return. The T-ECU controls the shift-stage in the automatic shift-mode “D” until the detection of the operation of the shift-lever after the standby-period passes.
