摘要:
An installation structure of a one-way clutch (5) having an inner ring (5a) and an outer ring (5b) is provided. In order to prevent malfunction of the one-way clutch caused by a damage of a rivet (33), a first clearance (C1) between one face of a flywheel (4) and a top face of a head (34) of the rivet (33) is reduced to be narrower than a thickness (T1) of a stopper plate (32).

A control system for hybrid vehicle (Ve) to eliminate the shortage of drive force within the low-to-mid speed range in the hybrid mode. In a differential mechanism (5, 30, 40, 50, 60, 70, 80), a first rotary element (5a, 30a, 40a, 50a, 60a, 70a, 80a) is connected to an engine (1), a second rotary element (5b, 30b, 40b, 50b, 60b, 70b, 80b) is connected to a first motor (2), a third rotary element (5c, 30c, 40c, 50c, 60c, 70c, 80c) is connected to a second motor (3), and a fourth rotary element (5d, 30d, 40d, 50d, 60d, 70d, 80d) is connected to an output unit (7, 201, 221). A third motor (4) is connected to the output unit (202, 222). When the controller (11) determines that the hybrid vehicle (Ve) is propelled by the torque of the engine (1), the first motor (2) and the second motor (3) generate torques in a same direction as an engine torque to propel the vehicle (Ve) in a forward direction, and the third motor (4) generates a torque in the forward direction to propel the vehicle (Ve) together with the engine torque.

A vehicle control system vehicle control system to remove deposition from the purification system without generating noises and vibrations is provided. The vehicle control system comprises a controller (8) that operates the vehicle (Ve) having an engine (1) autonomously, and that removes deposition from a purification system (35). The controller (8) is configured to: obtain an amount of deposition on the purification system (35); determine a presence of a passenger in the vehicle (Ve); and execute the removal control when an amount of the deposition on the purification system (35) exceeds a threshold value (α, ß). The threshold value (α, ß) includes a first threshold value (α) used when the vehicle (Ve) is propelled while carrying a passenger, and a second threshold value (ß) used when the vehicle is propelled autonomously without carrying a passenger that is smaller than the first threshold value (α).

An electric motor (10) comprising: - a rotor member (16) rotatably coupled to a rotation shaft (20) of longitudinal axis (X) and a surrounding stator member (18) comprising a first and a second opposite winding heads (18b,18c) having each inner and outer radially located sides, - a cooling system (CS) comprising: a cooling fluid pipe (24) arranged above the stator member and having cooling fluid projecting orifices (24a-c) for projecting cooling fluid downwardly towards the outer side (18b1) of a winding head (18b), a rotating member (26) rotatably coupled to shaft (20) and having an outer peripheral surface (26a) arranged inwardly relative to the inner side (18b2), the rotating member (26) configured to collect on its surface (26a) cooling fluid that has flown downwardly through the winding head from its outer side to its inner side and to distribute collected cooling fluid towards the latter by centrifugal force, while the rotating member (26) rotates.
摘要:
A control system for a power transmission (1) unit configured to shift an operating mode smoothly by manipulating engagement devices (CL1, CL2), and to simplify a structure of the power transmission unit (1). The control system is configured to reduce a speed difference between an axially stationary engagement element (20) and a reciprocatable engagement element (21) of a second engagement device (CL1) when shifting from a first continuously variable mode to a second continuously variable mode by engaging the second engagement device (CL1). After the second engagement device (CL1) has been engaged completely, a first engagement device (CL2) is disengaged.
摘要:
A control system for a vehicle that prevents an unintentional mode change when a command signal cannot be transmitted to an engagement device. In the vehicle, HV-Lo mode is established by connecting a carrier 14 to a carrier 20 by a first clutch CL1 while disconnecting the carrier 20 from a ring gear 18 by a second clutch CL2, and HV-Lo mode is established by disconnecting the carrier 14 from the carrier 20 by the first clutch CL1 while connecting the carrier 20 to the ring gear 18 by the second clutch CL2. A normally stay clutch is used as at least one of the first clutch CL1 and the second clutch CL2.
摘要:
When an engine (6) is started by causing a first motor (7) coupled to first drive wheels to motor the engine (6) while a hybrid vehicle (1) is turning with the engine (6) stopped, an electronic control unit (15) controls output torque of a second motor (11) coupled to second drive wheels, in such a direction as to curb change of a steering characteristic of the hybrid vehicle (1) due to change of drive torque of the first drive wheels induced by motoring of the engine (6) by the first motor (7).
