    Abstract: During changing of a shift range (for example, from P-range to NotP-range), an SBW-ECU determines whether it is in a range-change delay condition (a switching completion time of the shift range is delayed than a normal switching completion time). When it is determined that it is in the range-change delay condition, it is determined whether a target range should be changed to a safer range (for example, P-range). As a result, when it is determined that the target range should be changed to the safer range, the target range is changed to the safer range. Thereby, even if a driver determines that the shift range cannot be changed before the switching completion of the shift range and the driver gets off the vehicle, the shift range can be changed to the safer range (P-range).

    Abstract: At least some implementations of a gear shift control system include first and second drive members, a drivetrain selectively driven by the first and second drive members and a retainer. The drivetrain includes a first input driven by the first drive member, a second input and an output coupled to and selectively driven by both the first input and the second input. The second drive member is coupled to the second input to drive the output through the second input during a second mode of operation to cause a transmission gear shift. The retainer is selectively coupled to the second input and movable between first and second positions to permit movement of the second input during the second mode of operation and prevent such movement during a first mode of operation.

    Abstract: A method for updating shift position thresholds for a multi-speed transmission is provided. The multi-speed transmission includes an input member for connection to a prime mover and an output member, the output member selectively couplable to the input member via a plurality of gear ratios, and a position sensor for providing data indicative of a position of a shift actuator for selecting between the plurality of gear ratios. The method includes: detecting a request to change the gear ratio between the input member and the output member; and subsequent to detecting the request to change the gear ratio, i) comparing a velocity of the output member to a prescribed velocity, ii) upon the velocity of the output member increasing and being less than the prescribed velocity, storing the position provided by the position sensor as a synchronization position, iii) upon the velocity of the output member corresponding to the prescribed value, storing the position provided by the position sensor as an endstop position, and iv) calculating a threshold position for the shift actuator based on the synchronization position and the endstop position.

    Abstract: A SBW-ECU switches over a shift range to a selected range by rotationally driving a motor to a target position corresponding to the selected range. When a direction of rotation of the motor is the same as a direction toward the target position and a difference between the target position and a present position is larger than a threshold value in a case that the selected range is changed during rotational driving of the motor, the target position is updated to a post-change target position. When the direction of rotation of the motor is opposite to the direction toward the target position or the difference between the target position and the present position is smaller than the threshold value in the case that the selected range is changed during rotational driving of the motor, the target position is updated to the post-change target position after completing the switchover to the pre-change selected range.

    Abstract: A transmission operating mechanism includes an operating housing, wherein an inner shifting shaft is provided in the operating housing, and the operating housing is provided with, from left to right, a first position-limiting structure installation hole, a shifting block installation cavity, a second position-limiting structure installation hole and a balancing spring installation cavity; and a shifting block is installed in the shifting block installation cavity and is connected to the inner shifting shaft via a shifting block positioning pin. The spatial position of the operating housing is fully utilized to effectively arrange each functional component, and the requirement for modification is fully considered within the limited dimensional range. Therefore, various operation modes may be achieved by simply providing several modified parts without changing the operating housing.
