摘要:
A vehicle air-conditioning system limits electric power used by an electric motor for a compressor in a prescribed fashion that quickly removes fog from the windows when a defroster mode is selected. When the defroster mode is selected, the limit on the electric power used by the electric motor is lifted, and the number of revolutions of the compressor is set to a high level to raise the dehumidifying and cooling capability to quickly remove moisture from the windows.

In a compressor control system for a vehicle air conditioner, a hybrid ECU of the vehicle controls a rotation speed of a compressor electric motor. In this case, an output circuit, which outputs a driving signal for driving the compressor electric motor, only needs to be newly provided in the hybrid ECU when a hybrid vehicle or an electric vehicle is manufactured based on an engine vehicle. Therefore, a high cost is not caused even when the output circuit is provided in the hybrid ECU which should be newly designed and manufactured. In addition, because the output circuit does not need to be provided in an air-conditioning ECU which is an existing component of the engine vehicle, the air-conditioning ECU in the engine vehicle can be directly applied to that in the hybrid vehicle without a substantial hardware change. Therefore, design cost can be reduced.

In an air conditioner for a hybrid vehicle, when a residual charging degree of a battery becomes equal to or lower than a target degree, the electrical motor generator is driven by a vehicle engine so that the battery is charged through the electrical motor generator. When the engine is driven, the target degree of the battery is set higher than that when the engine is stopped so that a charging operation tends to be required while the engines driven. Accordingly, the frequency for starting the engine only for charging the battery is reduced.

When an after-evaporation temperature TE remains below the wet-bulb temperature Twet, the compressor 231 is intermittently operated for a predetermined time after the elapse of a first time To from compressor 231 stopping. On the other hand, when the after-evaporation temperature TE is higher than the wet-bulb temperature Twet, the intermittent operation mode stops. This reduces dispersion of offensive smells from the evaporator.

In a hybrid vehicle including an engine and an electric motor both for running the vehicle, an air conditioner includes a compressor driven by the engine, and an engine controller controls the operation of the engine based on a condition of the air conditioner and a condition of the vehicle except the air conditioner. While the air conditioner performs a defrosting control for a windshield, the engine controller drives the engine irrespective of the condition of the vehicle except the air conditioner. On the other hand, when the defrosting control is not performed, the operation of the engine is controlled in accordance with the condition of the vehicle, for example.

In a vehicle air-conditioning system, a supply of electric power to a first electric heater and a supply of electric power to a second electric heater are duty controlled at the same duty ratio in such a manner that the supply of the electric power to the second electric heater is phase shifted by one half of a period from the supply of the electric power to the first electric heater.
摘要:
In an electrical compressor having a motor and an electrical circuit integrated with a compression portion, a part of electrical components of the electrical circuit is disposed in spaces between a cylindrical outer surface of a motor housing and an imaginary flat surface that imaginarily contacts the cylindrical outer surface. Therefore, the spaces can be used effectively, and the electrical compressor can be downsized. Further, the part of the electrical components can be effectively cooled by refrigerant in the motor housing. On the other hand, the outer surface of the motor housing is used as one surface defining an inner space of a casing for accommodating the electrical circuit. In this case, the electrical circuit can be effectively cooled by refrigerant in the motor housing.

An automotive air conditioning system is provided to be able to minutely control the air blow temperature independently of the ambient temperature to maintain the compartment always pleasant. The difference between the revolution speed of a compressor with a temperature setting lever for setting the revolution speed of the compressor set in the left end position and the revolution speed of the compressor with the temperature setting lever set in the left end position is increased in the mid summer or mid winter and reduced in the spring or autumn, whereby the air blow temperature can be minutely controlled to make the inside of the compartment always pleasant.

A steering angle indicating system for a vehicle includes a plurality of rotational angle sensors arranged within a steering wheel of the vehicle, each thereof producing an electric signal indicative of a turn angle of the steering wheel, an indicating unit responsive to the turn angle signals from the rotational angle sensors to compute the turn direction and the turn angle of the steering wheel and to indicate a result of the computation, and a power supply circuit supplied with electric power from a load side of a horn switch prearranged within the steering wheel. The system prevents the occurrence of a collision caused by careless starting of the vehicle by the driver.

A learning device that affects only the input-output relationships that should be additionally learned. A learning NN unit 8 capable of executing additional learning is provided separately from a learned NN unit 4 which is a basic control unit. The learned NN unit 4 produces a basic output in response to an input signal from a signal input unit 14, the learning NN unit 8 produces a correction amount desired by an individual person, and a desired control is performed based on the total value. When the output is changed, a difference is calculated between the changed output value and the basic output value from a first output unit 15, and the learning NN unit 8 executes the additional learning based upon the difference and the input value at this moment in compliance with a back-propagation method.
