Title:
VEHICLE DRIVE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/043077
Kind Code:
A1
Abstract:
A vehicle drive control device of the present invention, in a vehicle provided with left and right motors (6, 6) that individually drive left and right drive wheels (2, 2), has a torque control means (30) that controls the torque of each motor (6) in accordance with a command torque through the use of a command current. The drive control device is provided with a motor temperature detection means (Sc) that respectively detects the temperatures of the left and right motors (6, 6) and a steering angle detection means (Sa) that detects the steering angle. The drive control device is further provided with a command current correction means (33) that, when the difference between the detected motor temperatures is at or above a threshold value and the steering angle is at or below a set value, corrects the command current so that output-torques output from the left and right motors (6, 6) will be the same torque with respect to the command torque applied to the torque control means (30).
