Patent number: 10158320Abstract: A shift range switchover control ECU controls a motor of an actuator provided to switch over a shift range of a vehicle and includes a temperature estimation part and a driving control part. The temperature estimation part estimates a temperature of the motor 11 based on a driving state of the motor. The driving control part controls driving of the motor and limits the driving of the motor when an estimated temperature exceeds a protection temperature. The temperature estimation part calculates, based on a final temperature indicating the estimated temperature of a system stop time, a restart-time temperature, which is the estimated temperature at time of turning on a starting switch of the vehicle again after turning off the starting switch, and a delay period, during which the temperature estimation part continues to calculate the estimated temperature after turning off of the starting switch. It is thus possible to properly estimate the temperature of the motor.Type: GrantFiled: August 16, 2016Date of Patent: December 18, 2018Assignee: DENSO CORPORATIONInventor: Tsuyoshi Kawabata

Patent number: 10145470Abstract: A continuously variable transmission (CVT) for use with a torque generating mechanism includes an input member connectable to the torque generating mechanism, an output member, a variator assembly, and a controller. The controller is programmed to control a change-of-mind shift of the CVT requesting a transition from an initially-requested shift to a next-requested shift before completion of the initially-requested shift. Additionally, the controller is programmed to execute a method by detecting the change-of-mind shift, determining an acceleration profile of the input member for the change-of-mind shift using a calibration map indexed by a starting and target ratio of the variator assembly, and calculating a required ratio of the input and output pulleys using the acceleration profile. The controller then commands a clamping pressure of the variator assembly to thereby achieve the calculated required ratio. A vehicle includes an engine and the CVT noted above.Type: GrantFiled: February 9, 2016Date of Patent: December 4, 2018Assignee: GM Global Technology Operations LLCInventors: Zhen J. Zhang, Paul G.
