Embodiment Construction

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

[0033] This hybrid vehicle (hereinafter referred to as "HEV") is a vehicle including not only a general passenger car but also a bus or a truck, a pickup truck, etc., and includes a hybrid system 30 having The engine 10 and the motor generator 31 are controlled complexly. In addition, this HEV includes drum brakes 92 as a braking system that applies frictional braking force to each wheel. Furthermore, this HEV includes a relative relationship acquiring device 85 for acquiring a relative relationship between the host vehicle and the preceding vehicle.

[0034] In the engine 10 , a crankshaft 13 is rotationally driven by thermal energy generated by combustion of fuel in a plurality (four in this example) of cylinders 12 formed in an engine body 11 . A diesel engine or a gasoline engine...

Abstract

If a deceleration command (C1) is provided and the total braking force (B1) is set to the demand braking force (B2) based on the deceleration command (C1), this hybrid vehicle is configured in such amanner that a control device (80) implements control to set the total braking force (B1) to be greater than the demand braking force (B2) by increasing only the regenerative braking force (B5) generated by a motor generator (31) on the basis of the relative relation (R1) acquired by a relative relation acquisition device (85).

Description

technical field [0001] The present disclosure relates to a hybrid vehicle and a control method thereof, and more specifically, to a hybrid vehicle and a control method thereof that increase fuel economy by increasing the amount of regenerative power generated by a motor generator during deceleration of the hybrid vehicle. Background technique [0002] In recent years, a hybrid electric vehicle (hereinafter referred to as "HEV") including a hybrid system that is comprehensively controlled according to the operating state of the vehicle has attracted attention from the viewpoint of fuel economy improvement and environmental measures. engine and motor generator. In this HEV, the motor generator is used to assist driving force during acceleration or start of the vehicle, and the motor generator is used to perform regenerative power generation during coasting or deceleration. [0003] Coordinated regeneration is known in which the frictional braking force of a braking system tha...
