CONTROL DEVICE FOR GEAR SELECTION IN AN ELECTRICALLY DRIVEN VEHICLE AND A METHOD FOR GEAR SELECTION CONTROL IN AN ELECTRICALLY DRIVEN VEHICLE
The present disclosure relates to a control system for gear selection of a transmission for an electrically driven vehicle, wherein said control system comprises a gear selection control device and a gear selection input device, the gear selection input device comprising a user input element for selectively holding a constant gear, and wherein said control system is adapted to hold a constant gear of the transmission while the user input element is activated. The disclosure also relates to a transmission arrangement, a powertrain, a vehicle and a method.
Gear Shifting Process for Powertrain Transmission
A transmission associated with a powertrain receives torque from a power source and includes a plurality of gear sets that can be selectively engaged and released. To shift gear sets, a shifting process conducted by an electronic controller may estimate a torque assist capacity of the power source to provide or accommodate changes in torque during the gear shift. If the torque assist capacity is less than a gear shift torque value, the shifting process prevents or ignores the gear shift.
