摘要:
A drive control apparatus for an automotive vehicle having an electric motor and an engine operated by combustion of a fuel, the drive control apparatus including a drive source selecting device for selecting an engine drive mode or a motor drive mode on the basis of a first value in the engine drive mode of a physical quantity relating to a condition of the engine and a second value of the same physical quantity reflecting energy conversion efficiencies of the electric motor, an electric generator and an electric energy storage device during an electricity generating mode. The physical quantity is preferably a fuel consumption amount by the engine. The drive control apparatus may also include an engine output determining device that optimizes the efficiency of the system by determining the output of the engine so as to power the vehicle and also provide surplus power to operate the electric generator and charge the electric energy storage device. An enlarging device may also be included to increase the output of the electric motor to prevent excessive charging of the electric energy storage device.

A hybrid drive system for a motor vehicle, wherein a controllable device such as an automatic transmission or a center differential device is disposed between drive wheels of the vehicle and a drive power source consisting of an engine operated by combustion of a fuel, and an electric motor operated with an electric energy, and the engine and/or the electric motor is/are operated for driving the motor vehicle in different running modes. The controllable device is controlled by a control device on the basis of an input torque received by the controllable device. The control device is adapted to estimate the input torque of depending upon a currently selected one of the running modes, or effect learning control of the controllable device in different manners corresponding to the different running modes.
摘要:
A hybrid drive system including an engine and an electric motor at least one of which is operated as drive power source to drive a motor vehicle in a selected one of different operation modes. The system is adapted to prevent concurrent operations to change the operation mode and the speed ratio of a power transmitting device or the ratio of torque distribution to front and rear drive wheels, or concurrent operations to change the operation mode and switch the power transmitting device from a non-drive state to a drive state, for avoiding a shock due to a torque variation which would arise from the concurrent operations. The system is alternatively adapted to cut a power transfer from the drive power source to the power transmitting device, or hold the output of the drive power source substantially constant, when the power transmitting device is switched from the non-drive state to the drive state.

摘要:
A controller for a hybrid vehicle (HV) idles first an internal combustion engine (ICE) when it is determined in advance that a load on the HV or a motor will increase, and thereafter switches to a travelling mode in which the ICE is used. Based on output of a vehicle weight sensor, a gradient sensor, a towing sensor, a start/power mode switch and other on-board sensors or switches, it is determined in advance that a load on the HV or the motor will increase. Otherwise, based on information obtained from a navigation system or from another vehicle to be towed, it is determined in advance that a load on the HV or the motor will increase. Based on a difference of output between an open air temperature sensor and a cabin temperature sensor, a load on an on-board appliance is detected, and based on the detected load, it is determined in advance that a load on the HV or the motor will increase. Thus, a delay in following the ICE in response to the switching of travelling modes can be decreased or remedied.
