DRIVE SOURCE CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/066464

Kind Code:

A1

Abstract:

Provided is a drive source control device that is able to output the torque indicated by a supplied command value and is able to stabilize vehicle behavior even when a change in the angular speed occurs in a left drive wheel and/or a right drive wheel. This drive source control device (67) controls two drive sources (2L, 2L) in a vehicle. The drive source control device (67) is equipped with: the two drive sources (2L, 2L); left and right drive wheels (61L, 61R); and a power transmission device (3) that is arranged between the two drive sources (2L, 2L) and the left and right drive wheels (61L, 61R) and distributes power from the two drive sources (2L, 2L) to the left and right drive wheels (61L, 61R), thereby driving the left and right drive wheels (61L, 61R). The drive source control device (67) also is equipped with: an angular acceleration calculation means (71) that determines the angular acceleration of the drive wheels (61L, 61R) and/or the angular acceleration of the drive sources (2L, 2L); and a torque correction means (68) that uses the angular acceleration determined by the angular acceleration calculation means (71) to correct a command value regarding the respective outputs of the two drive sources (2L, 2L) and supplied from a command means (66a).
