Control of vehicle traction motor torque before stall launch

摘要

A controller (104) for controlling torque generated by at least one traction motor (116a, 116b) of a vehicle (100) before a vehicle launch, comprising: means to determine that torque demand increases while simultaneously at least one brake (111) of the vehicle is in an applied state; means to, in dependence on the determination, limit torque generation by the traction motor in response to torque demand; and means to remove the limit in dependence on release of the at least one brake.
