Output torque control device

Abstract

The output torque of the driving source is made into the detected torque determined when the value corresponding to the operation of the accelerator pedal exceeds a predetermined value, the first torque determined based on the vehicle speed and the gear ratio, the detected torque and the first rotational speed The second torque determined based on the accelerator pedal operation amount and the second torque, the third torque determined based on the accelerator pedal operation amount and the fourth torque determined based on the accelerator pedal operation amount, as long as the third torque is smaller than the fourth torque torque, the output torque is limited to the third torque. When the torque at the time of detection is greater than the first torque, the third torque is determined so as to suppress the increase compared to the case where the torque at the time of detection is not more than the first torque.

Description

technical field [0001] The present invention relates to an output torque control device that controls the torque output from a drive source of the vehicle when the vehicle is started. Background technique [0002] Conventionally, as a control device that controls the output torque of a drive source when a vehicle starts, for example, a control device described in Patent Document 1 below has been proposed. According to this control device, the target output torque is set, and the output torque of the driving source is controlled so that the output torque approaches the target torque, so that when the vehicle is accelerated when the accelerator pedal is operated, it is possible to obtain smooth acceleration without affecting the acceleration response. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2008-280926 [0004] However, when the actual output torque is controlled so that the actual output torque approaches the target torque, the control process becomes comp...

Problems solved by technology

[0004] However, when the actual output torque is controlled so that the actual output torque approaches the target torque, the control process becomes complicated and the control process is delayed, compared with the case where the output torque is determined by the state of the driving source or the transmission.
