Embodiment Construction

[0032] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. figure 1 A hybrid vehicle constituted by an embodiment of the present disclosure is shown.

[0033] The hybrid vehicle (hereinafter referred to as "HEV") is a vehicle that includes not only a general passenger car but also a bus, a truck, a small truck, and the like, and includes a hybrid system 30 that has a function of changing the operating state of the vehicle according to the operating state of the vehicle. The engine 10 and the motor generator 31 are controlled in a complex manner. Further, this HEV includes a drum brake 92 as a braking system that applies friction braking force to each wheel. Furthermore, the HEV includes a relative relationship acquiring device 85 that acquires the relative relationship between the host vehicle and the preceding vehicle.

[0034] In the engine 10 , the crankshaft 13 is rotationally driven using thermal energy gener...

Abstract

The control device (80) is configured such that when a deceleration command (C1) is issued and the overall braking force (B1) is set to a required braking force (B2) based on the deceleration command (C1), the control device (80) performs control based on the relative The relative relationship (R1) acquired by the relationship acquiring means (85) is to increase only the regenerative braking force (B5) of the motor generator (31) to make the overall braking force (B1) larger than the required braking force (B2).

Description

technical field [0001] The present disclosure relates to a hybrid vehicle and a control method thereof, and more particularly, to a hybrid vehicle and a control method thereof that increase the amount of regenerative power generated by a motor generator during deceleration of the hybrid vehicle to improve fuel economy. Background technique [0002] In recent years, attention has been paid to a hybrid vehicle (hereinafter referred to as "HEV") including a hybrid system that is complexly controlled in accordance with the operating state of the vehicle from the viewpoints of fuel economy improvement and environmental measures. engine and motor generator. In this HEV, when the vehicle is accelerating or starting, the motor generator is used to assist the driving force, and on the other hand, the motor generator is used to perform regenerative power generation when coasting or decelerating. [0003] In order to efficiently increase the regenerative power generation amount of the...
