METHOD FOR CONTROLLING AN AUTOMATIC TRANSMISSION OF A VEHICLE

A method for controlling an automatic transmission of a vehicle includes: sensing a speed of the vehicle; sensing an acceleration of the vehicle along three spatial axes; determining that the vehicle is in a jump state associated with the vehicle being off a ground surface, the jump state being defined at least in part by the acceleration of the vehicle along the three spatial axes and the speed of the vehicle; and controlling the transmission according to a jump strategy in response to determining that the vehicle is in the jump state. Other methods for controlling an automatic transmission of a vehicle are also contemplated.

Control device

A control device performs upshifting in a state in which an operating point of a rotating electrical machine for outputting requirement-based torque at wheel-based rotational speed falls within an operable range of the rotating electrical machine both before and after shifting a shift speed by the upshifting, and in which before shifting the shift speed, output torque from the rotating electrical machine is less than or equal to determination torque (T1), the wheel-based rotational speed being rotational speed of the rotating electrical machine based on rotational speed (V) of a wheel, the requirement-based torque being output torque from the rotating electrical machine based on required wheel transmission torque, and the determination torque (T1) being torque obtained by subtracting an amount of increased torque (ΔTmg) resulting from torque increase control from maximum torque (Tmax) that can be outputted from the rotating electrical machine at the wheel-based rotational speed.

Transmission shifting control system

A vehicle includes a powerplant, at least one drive wheel, a transmission, and a controller. The powerplant is configured to generate power to propel the vehicle. The transmission is configured to deliver power from the powerplant to the at least one drive wheel. The controller is programmed to, in response to a scheduled upshift of the transmission and detection of a set of conditions that are indicative of the vehicle climbing while on loose terrain, override upshifting the transmission and maintain a current gear of the transmission. The controller is further programmed to, in response to the scheduled upshift of the transmission and non-detection of at least one condition of the set of conditions that are indicative of the vehicle climbing while on loose terrain, upshift the transmission.

The disclosure provides a vehicle and a method for controlling the vehicle. The vehicle includes: an engine; a transmission configured to transmit power from the engine to drive wheels; a deceleration factor detection device configured to detect a deceleration factor that is present ahead of the vehicle; and an electronic control unit configured to maintain a speed ratio of the transmission as a current speed ratio on condition that the deceleration factor is detected by the deceleration factor detection device, and change the speed ratio stepwise to a lower speed side than the current speed ratio and maintain the changed speed ratio, in response to a deceleration request from a driver.

CONTROL METHOD FOR VEHICLE AND CONTROL DEVICE FOR VEHICLE

A vehicle selects a parking position when a state in which a P range button (2) is operated overlaps a state in which an N range button (4) is operated. Thereafter, the vehicle maintains the parking position when the operation of P range button (2) is released and switched to the state in which N range button (4) is operated. This allows the vehicle to suppress the selection of a shift position that is different from the intention of the driver.

Method and device for controlling a transmission of a vehicle

A method for controlling a transmission of a vehicle includes: determining whether a controller receives an acceleration pedal off signal corresponding to a lift foot up (LFU) shift request signal from an acceleration pedal sensor; determining whether an output signal value of a brake pedal sensor detecting a position value of a brake pedal is less than a brake reference value when the acceleration pedal off signal is received; determining whether a gear shifting progressing rate of the transmission performing a LFU shift in response to the LFU shift request signal is less than a progressing rate reference value when an output signal value of the brake pedal sensor is equal to or greater than the brake reference value; and controlling the transmission to hold the LFU shift when the gear shifting progressing rate of the transmission is less than the progressing rate reference value.
