  • Patent number: 10689001
    Abstract: A method of controlling a dual clutch transmission power on up shift including an on-coming clutch and an off-going clutch. The method includes implementing a prep phase comprised of decreasing torque on the off-going clutch, monitoring the off-going clutch speed to determine a slip point, and adding a bump torque to the off-going clutch when the off-going clutch reaches the slip point. The method implements a torque phase transferring torque from the off-going clutch to the on-coming clutch by increasing torque on the on-coming clutch towards an engine torque, decreasing torque on the off-going clutch, and simultaneously keeping the combination of torques greater than the slip point.

It is determined whether a second signal from a second ECU is received, which second signal indicates successful engagement of the park function. If it is not received, a second audio function is implemented and, if it has been received, a third audio function is implemented. The second audio function produces sound that is dissonant with respect to the sound produced by the first audio function, and the third audio function produces sound that is consonant with respect to the first audio function.

    Abstract: In a hybrid vehicle provided with a continuously variable electric transmission mechanism capable of sequential shift mode, a minimum engine rotational speed is specified for each gear specified in the sequential shift mode so that the lower the gear, the greater the minimum engine rotational speed. When the engine rotational speed has decreased to the minimum rotational speed while driving in the sequential shift mode, an upshift lamp of a gear shift indication device is turned on to prompt the driver to manually shift to a higher gear. As the driver shifts to a higher gear in response to the prompt, the minimum engine rotational speed is specified to a lower value. That allows for further decrease of the engine rotational speed and improves fuel consumption rate.

    Abstract: A control device for controlling a front wheel drive force and a rear wheel drive force of a vehicle that includes a transmission comprises: a first controller for controlling a drive force of a main drive wheel and a drive force of an auxiliary drive wheel, the drive force of the main drive wheel being one of the front-wheel drive force and the rear-wheel drive force, and the drive force of the auxiliary drive wheel being another of the front-wheel drive force and the rear-wheel drive force; and a second controller for detecting whether a speed-change ratio of the transmission has changed. In a case that the second controller has detected that the speed-change ratio has changed, the first controller increases the drive force of the auxiliary drive wheel and reduces the drive force of the main drive wheel.

  • Patent number: 8725367
    Abstract: In a control apparatus and a control method for a vehicle automatic transmission in which a plurality of gears with different speed ratios are achieved by selectively engaging a plurality of friction engagement devices and a one-way clutch, if an acceleration request is made in the case where the one-way clutch is in an idling state when a first predetermined gear is to be achieved by engaging the one-way clutch, a pre-synchronization control is executed to transmit torque through a predetermined friction engagement device used to achieve a second predetermined gear at which the one-way clutch is maintained in an idling state, and to continue to change a rotational direction of the one-way clutch toward a rotational direction in which the one-way clutch is brought to a synchronized state, according to the acceleration request.

  • Patent number: 8688339
    Abstract: A method and system provides a Neutral Tow mode in a vehicle with a shift-by-wire transmission by displaying a Neutral Tow mode option when the transmission control mechanism has been used to select Park, an ignition switch is on, and an engine is off or an information button has been pushed and entering a Neutral Tow mode upon detecting a triggering event. The Neutral Tow mode is canceled upon detecting a certain sequence of events, such as turning on the ignition switch, depressing and holding a brake pedal, and selecting Park. When in Neutral Tow mode the transmission will stay in Neutral, without automatically shifting to Park or using battery power, thereby enabling the vehicle to be towed long distances without draining battery power.

  • Patent number: 8682548
    Abstract: A method of controlling a vehicle washing mode for a vehicle equipped with shift-by-wire shifting device, may include performing an N-range-off determining step that determines whether a shift lever is in an N-range when an engine stops, performing an ACC determining step that determines whether the vehicle is in an ACC state, and performing a shifting step that shifts a P-range state of a transmission to a N-range state thereof by operating an actuator, when the N-range-off determining step determines that the shift lever is in the N-range when the engine was stopped, and when the ACC determining step determines that the vehicle is in the ACC state.

  • Patent number: 8676483
    Abstract: Guidance control device, methods and programs control an in-vehicle apparatus of a vehicle. The devices, methods, and programs access vehicle state information that specifies a state of the vehicle and determine whether a vehicle state condition is established based on the accessed vehicle state information. The devices, methods, and programs access driving environment information that specifies a driving environment of the vehicle and determine whether a driving environment condition is established based on the accessed driving environment information. The devices, methods, and programs generate guidance based on whether the vehicle state condition is established and whether the driving environment condition is established and cause the generated guidance to be output on a display.

  • Patent number: 8649951
    Abstract: A shifting apparatus includes an actuator to direct a travel range setting of a vehicle transmission, a selector to indicate a desired travel range setting, a transmission controller to move the actuator into the travel range setting in response to the desired travel range setting of the selector, and a restrictor to restrict an output of a drive motor if the vehicle transmission is in a travel range setting other than the desired travel range setting. A method to control a vehicle transmission includes detecting a travel range setting of the vehicle transmission, detecting a desired travel range setting of a selector, and entering a limp-home mode if the detected travel range setting is different from the desired travel range setting and a detected vehicle travel direction corresponding to the detected travel range setting is the same as a desired travel direction corresponding to the desired travel range setting.

  • Patent number: 8634995
    Abstract: A voting strategy is used to determine the mode state of a transmission when a vehicle is restarted. A Powertrain Control Module, a Transmission Range Control Module, and a Gear Shift Module communicate through a communication network during execution of the voting strategy. Each module stores a remembered mode state (Normal, Neutral Hold, Neutral Tow, etc.) of the transmission in non-volatile memory. Upon module initialization, the Powertrain Control Module will compare its own remembered mode state of the transmission with the remembered mode state reported by the other two modules. A basic voting strategy is that if two of the three modules report the same remembered mode state then the Powertrain Control Module changes the transmission to that same mode state.

  • Patent number: 8630781
    Abstract: A regeneration energy shunt system utilizes a module to monitor the power bus voltage and can divert excess regeneration energy to a resistor array to dissipate the excess regeneration energy. The module can monitor the state of charge of an energy storage device to ascertain when excess regeneration energy condition exists. The resistor array can include a plurality of resistors. The module can ascertain the number of resistors needed dissipate the excess regeneration energy and selectively direct the excess regeneration energy to the required number of resistors. The module can dynamically switch which resistors are used to dissipate the excess regeneration energy and can thereby even out the loading across the resistors. The module can ascertain a state of health of the individual resistors and remove unhealthy resistors from service, report the state of health of the resistors, and initiate changes in operation based thereon.
