  • Patent number: 9283948
    Abstract: In a vehicle that includes an engine, a motor, a generator, a battery electrically connected to the motor and the generator, and a transmission provided between the motor and an output shaft coupled to a drive wheel, an ECU executes “battery-less travel control” in which, at the time of a failure of the battery, the battery is isolated from the motor and the generator, the generator is caused to generate electric power by generating a torque, corresponding to an accelerator pedal operation amount, from the generator, and the vehicle is caused to travel by driving the motor using the electric power generated by the generator. The ECU suppresses losing a balance of input and output electric powers between the generator and the motor by filtering the accelerator pedal operation amount when a vehicle speed exceeds a limit vehicle speed during the battery-less travel control.

  • Patent number: 9273777
    Abstract: In a manual transmission mode, a downshift instruction signal is outputted by a position sensor, and a shift range is lowered by one gear, as a result of an operation of a shift lever by the driver. The driving force of the vehicle is increased through downshifting. The number of times of downshifting within a predefined time is limited to a predefined number of times.

  • Patent number: 9216664
    Abstract: In a hybrid vehicle including an engine, a motor, a generator, and a battery that is electrically connected to the motor and the generator, an ECU performs “battery-less travel control” enabling the vehicle to travel when a fault occurs in the battery by disconnecting the battery from an electrical system including the motor and the generator and driving the motor using power that is generated by the generator using the power of the engine. When the battery-less travel control is underway and a vehicle speed V exceeds a vehicle speed limit Vsh, the ECU implements a vehicle speed limitation. As a result, a control mode of the motor is less likely to shift to a rectangular control mode during the battery-less travel control.

  • Patent number: 8057357
    Abstract: An object oil temperature is determined by adopting a gradual change process for an oil temperature of a cooling lubricant oil, which is used to lubricate and cool down a motor and a transmission constructed to cause an output power of the motor to be subjected to speed change and to be transmitted to a driveshaft. A load factor of the motor is subsequently set based on the set object oil temperature and a motor coil temperature. A motor torque command is set with the load factor, and the motor is then driven and controlled to ensure output of a torque equivalent to the set motor torque command. This arrangement drives and controls the motor with consideration of the oil temperature of the cooling lubricant oil and thus ensures more adequate actuation of the motor, compared with a conventional drive control without consideration of the oil temperature of the cooling lubricant oil.

  • Patent number: 5881288
    Abstract: A program development system in which the debugging apparatus is informed of all of the optimization processes which have been performed. A primitive storage unit stores record information for the optimization processes. The input unit receives an input of a variable and a value, or an input of a line where execution is to be halted. The primitive combining unit obtains record information showing the optimization processes. The code execution unit executes the execution code. The variable operation unit obtains the value of a variable based on relations between variables and resources. The output unit displays the obtained value of the variable. The line display unit displays the program or the generated execution code. The line information display unit displays, in line units, information relating to the optimization performed for each line, The operation-possible variable display unit displays, for each line, variables which can be set and referred to in the line.
