摘要： A continuously variable transmission (CVT) for a vehicle includes an input member, an output member and a variator assembly including a first pulley rotatably coupled to the input member and a second pulley rotatably coupled to the output. The first and second pulleys are rotatably coupled by a flexible continuous rotatable device. A control system is provided including an instruction set executable to determine an initial variator speed ratio of the variator assembly and detect an event causing a change in an operational state of the vehicle. The control system determines a compensation strategy to adjust the variator speed ratio in response to the change in the operational state of the vehicle and generates an adjusted variator speed ratio based upon the compensation strategy. The control system transmits the adjusted variator speed ratio to the variator assembly.

摘要： A system and method for controlling a vehicle having a continuously variable transmission (CVT) comprises a control system having at least one controller, an accelerometer and one or more sensors in communication with the at least one controller to monitor and detect a change in an operational state of the vehicle. The control system determines a vehicle acceleration rate with the accelerometer in response to the change in the operational state of the vehicle. An adjusted vehicle speed is computed based, at least in part, on the vehicle acceleration rate. A variator speed ratio is generated based upon the adjusted vehicle speed and transmitted to the variator assembly of the CVT.

摘要： Problems of work efficiency reduction by tire slip; durability reduction by tire damage; and large tire-changing costs for users are solved by preventing repeated tire slip occurrence in situations where tire slip likely occurs such as during excavation. A working vehicle of this invention has a work equipment, and an engine power is transmitted as driving force to the tires via a driving force transmission path. Driving force variation means for freely varying the driving force transmitted to the tires is provided in the transmission path of the working vehicle. Tire slip detection means detects tire slip occurrence. When the tire slip detection means detects tire slip, driving force measurement means measures the driving force at the time of tire slip detection. Driving force control means controls the driving force variation means such that the driving force becomes smaller than that at the time of tire slip detection.

摘要： When it is determined that the torque output from a power source is being automatically controlled, an ECU prohibits torque-boosting control of the power source during the torque phase when up-shifting, and performs up-shifting without performing torque-boosting control. In performing torque-boosting control, the driver demanded torque in response to the accelerator operation amount is used as the reference in setting amount of torque demanded from the power source.

摘要： A shift control system that controls gear shifts in a vehicle includes a transmission and a controller. The controller detects driving conditions of the vehicle, estimates a traction load of the vehicle and determines a current traction load of the vehicle. The controller shifts the transmission based on the current traction load and the estimated traction load if the driving conditions are met. The current traction load is based on a lateral acceleration signal and a longitudinal acceleration signal. The estimated traction load is based on a curb weight of the vehicle, a weight transfer gain and an acceleration signal.
