Problems solved by technology

However, there is still room for improvement in the method of utilizing the first relationship to the third relationship
For example, in US 2014 / 0191689 A1, there is no detailed study on the use of the first relationship on the basis of the second relationship and the third relationship
[0005] In addition, regarding power priority control, in US 2014 / 0191689 A1, the case where the sum P1+P2 of the power of the left and right motors is zero is mainly explained ([0197], [0217]), but for the sum of power P1+P2 There is still room for research when P2 is not zero

Abstract

The present invention provides a vehicle (10) and a control method thereof, wherein the motor control device (28) is based on the supplyable power (β) of the power source (20), and the left motor (16) and the right motor (18) respectively The power loss (L1, L2) corresponding to the rotation state quantity (Nmot), the target power difference (ΔTT) of the left motor (16) and the right motor (18), the target power sum of the left motor (16) and the right motor (18) (TRT_req) to set target left power (TM1) and target right power (TM2), and use target left power (TM1) and target right power (TM2) to control left motor (16) and right motor (18).

Description

technical field [0001] The present invention relates to a vehicle including a left motor mechanically connected to a left wheel and a right motor mechanically connected to a right wheel, and a control method thereof. Background technique [0002] US Patent Application Publication No. 2014 / 0191689 (hereinafter referred to as "US 2014 / 0191689 A1") discloses power control of left and right motor generators (electric motors) in a vehicle. That is, in US 2014 / 0191689 A1, a first relationship including the sum of the left wheel torque etc. and the right wheel torque etc., a second relationship including the difference between the left wheel torque etc. and the right wheel torque etc. are assumed, and A third relationship including the sum of the left power generated or consumed by the left motor generator and the right power generated or consumed by the right motor generator is included (claim 1). Furthermore, based on at least one of the first relationship and the second relatio...
