<p>#CMT# #/CMT# The method involves increasing an engine brake by successive increments (4) until falling beyond a maximum acceleration threshold if acceleration of a vehicle is above the threshold. The acceleration of the vehicle is compared with a minimal acceleration threshold (5) when the acceleration of the vehicle is less than the maximum acceleration threshold. The engine brake is decreased by successive increments (6) until falling above the minimal acceleration threshold when the acceleration of the vehicle is lower than the minimal acceleration threshold. #CMT# : #/CMT# An independent claim is also included for a control device for controlling an electrical motor of a car. #CMT#USE : #/CMT# Method for controlling an electrical motor of a vehicle e.g. electric vehicle such as battery electric vehicle, and hybrid vehicle. #CMT#ADVANTAGE : #/CMT# The method enables controlling engine torque actively so as to generate the engine brake when the vehicle is in descent while enabling increase and decrease of the engine brake by successive increments, thus assuring effective management of different levels of the engine brake. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart illustrating a method for controlling an electrical motor of a car. 1 : Step for determining speed, acceleration, number of revolutions of engine and degree of depression of accelerator pedal 2 : Step for comparing depression degree of accelerator pedal with a preset depression threshold 4 : Step for increasing engine brake 5 : Step for comparing acceleration of vehicle with minimal acceleration threshold 6 : Step for decreasing engine brake.</p> |
