摘要:
A control system for hybrid vehicles, in which a second prime mover is connected to an output member to which a power is transmitted from a first prime mover through a transmission in which a torque capacity is varied in accordance with an oil pressure, and which has a first hydraulic pump driven by the first prime mover for establishing an oil pressure to be fed to the transmission, and a second hydraulic pump arranged in parallel with the first hydraulic pump and driven by an electric motor. A torque limiter limits an output torque of the second prime mover temporarily to a predetermined torque which is lower than a maximum output torque, at a starting time of the first prime mover.

A control system for a hybrid vehicle that is capable of absorbing an inertial force which is generated during shifting of a stepped transmission. During shift control of the stepped transmission by a shift control device and before the shift control is completed, a during-shift drive control element controls a driving force which is output from a second drive unit such that a total driving force which is output from first and second drive units to the drive wheels equals a driver request output. Further, the during-shift drive control elements executes control so as to reduce a difference between the total driving force output to a drive wheel and the driver request output based on a change in a transmission force of the stepped transmission caused by a switch-over between a first brake and a second brake. Moreover, in an inertial phase of the switch-over between the first brake and the second brake, the during-shift drive control means controls a driving force of a second motor so as to absorb an inertial force which is generated by change in a rotational speed of the second motor with respect to the rotational speed of the drive wheel.

Methods and apparatus for a vehicle drive control apparatus changes in the transfer torque capacity of a power transfer device according to various states of operation with respect to at least one drive power source. The vehicle drive control apparatus includes a power transfer device that has a variable transfer torque capacity and the drive power sources that rotate a drive wheel via the power transfer device. A controller is included that causes a vehicle to selectively run in a variety of run modes that differ in states of operation with respect to at least one of the drive power sources. The controller changes the transfer torque capacity of the power transfer device in accordance with the various run modes. According to the vehicle drive control apparatus, a target oil pressure is raised by a predetermined amount when the mode of run is change, or when the vehicle descends in a direction opposite to a vehicle starting direction at the time of a hill climb start.
摘要:
A control system for a hybrid drive unit wherein an assist prime mover is connected through a transmission mechanism to an output member to which a torque outputted by a main prime mover is transmitted, a torque of said assist prime mover is limited within a preset range. Specifically, said torque is limited to an upper limit side in case the speed of said assist prime mover exceeds the preset value, and a lower limit value of the torque of the assist prime mover is set in case the output torque of said assist prime mover acts as a driving torque.

A control device of a hybrid drive unit, wherein an output member is connected to a first prime mover, and wherein a second prime mover capable of outputting at least one of a positive torque and a negative torque is connected through a transmission to said output member, comprising: a running restriction judger for judging that a running control of at least one of said first prime mover and said second prime mover is restricted, and a shift point changer for changing a shift point, in which a decision of a gear shift of said transmission is to be satisfied when the running restriction judger judges that the running control is restricted, different from the shift point of a case in which the running control is not restricted.
摘要:
A control system of a continuously variable transmission for a vehicle compensates for delays in an estimated input torque TINE based on a gradient value (variation) of the estimated input torque TINE,. For example, a friction force being applied to a driving belt of a continuously variable transmission is regulated according to the compensated estimated input torque TINE. Accordingly, an appropriate torque transmitting capacity is maintained in the transmission even at a rapid accelerating operation of the vehicle, while realizing good fuel efficiency.

A control apparatus for a drive system, in which a power source is activated to output a torque by an energy fed from an energy source so that the torque is transmitted to rotary members through a torque transmission element having a variable transmission torque capacity. The stop of the power source due to the exhaustion of energy is predicted to increase the transmission torque capacity of the torque transmission element.
摘要:
A control apparatus of a hybrid vehicle having a first drive unit, a second drive unit, a HV battery, a shift control element, a battery state detection element, and a shifting-time drive control element. Furthermore, in the control apparatus, a battery balance control element is formed by an engine control element, a first motor control element, a second motor control element and the shifting-time drive control element. If the shift control element determines there is a need for shifting carried out by a stepped transmission, the battery balance control element calculates the amount of increase/decrease in the amount of charge of the HV battery in accordance with the state of the HV battery, and changes the engine operation point on the basis of the calculated amount of increase/decrease in the battery charge, prior to the shifting.
