A vehicle includes an engine, a torque converter, a transmission, and a control device. The torque converter is coupled to the engine. The transmission is coupled to the torque converter. The control device is configured to control operation of the transmission. The control device includes a controller configured to perform shift hold control to prevent upshift of the transmission based on a lateral acceleration value of the vehicle. The controller is configured to permit the upshift of the transmission by only one gear shift stage in a case where a predetermined condition is met in the shift hold control. The predetermined condition includes a condition that an index value indicating a rotation speed of an output shaft of the torque converter be higher than a first threshold value.

A shifting system for a human-powered vehicle comprises a controller. The controller is configured to receive a driving torque and a cadence of the human-powered vehicle from at least one sensor. The controller is configured to determine a permitted shift timing based on the driving torque and the cadence. The controller is further configured to control a shift mechanism to perform a gear shift during the permitted shift timing in accordance with a permitted cadence range and a first threshold of the driving torque.

A human-powered vehicle control device is provided for controlling a human-powered vehicle. The human-powered vehicle control device includes an electronic controller controls a transmission device in accordance with a control state including first and second control states. The electronic controller changes the transmission ratio in accordance with a shifting condition including a reference value related to a traveling state of the human-powered vehicle in the first control state. The electronic controller changes the transmission ratio in accordance with an operation performed on an operation portion in the second control state. The electronic controller changes the shifting condition in accordance with a converging reference value for a case where the human-powered vehicle is in a riding converging state. The electronic controller changes the shifting condition in accordance with the converging reference value for a case where the control state is the second control state.

A method for standardizing a plurality of motor vehicles may include determining a characteristic value of an individual vehicle (50) based on transmission data for the individual vehicle from a data gathering device (6) associated with the individual vehicle. The transmission data for the individual vehicle may be associated with shifting characteristics of a transmission of the individual vehicle for at least one of an operation interval of the individual vehicle or a mileage of the individual vehicle. Additionally, the method may include assigning the individual vehicle to one of a plurality of profiles (10.1, 10.2, 10.3, 10.4, 10.5) of a classification (10) based at least in part on a magnitude of the characteristic value. The classification may be determined based at least in part on average values and a magnitude and frequency of deviations from the average values of transmission data gathered for a plurality of vehicles (5).

A manual mode training system for a vehicle having a manual transmission or a “manual mode” transmission controlled by a paddle shifter. The system includes a sensor to obtain force and position information from a foot pedal of the vehicle, and a processor to receive the information. Based on the information, the processor may predict an intended vehicle response, determine an appropriate gear to achieve the intended vehicle response, and notify a driver, through a haptic feedback mechanism, how to shift the transmission of the vehicle to reach the appropriate gear. A corresponding method is also disclosed and claimed herein.
