发明名称 Vehicle drive torque estimation device and drive torque estimation method, and four-wheel drive vehicle
摘要 The estimated drive torque calculation unit, is configured such that if the running condition determination unit determines that the transmission mechanism is in gear, and if the speed of rotation of the output shaft of the torque converter measured by the rotation speed measurement sensor is equal to or less than a predetermined speed of rotation, and if the rotation speed of the wheels measured by the wheel speed sensor is equal to or greater than a predetermined rotation speed, the torque combination unit calculates the first estimated drive torque as the engine estimated drive torque even if the slip ratio of the torque converter is equal to or less than a predetermined value, and even if the first estimated drive torque calculated by the first drive torque calculation unit is greater than the second estimated drive torque calculated by the second drive torque calculation unit.
